文摘Oral squamous cell carcinoma(OSCC)is a prevalent malignancy with high morbidity and mortality.Globally,about 400000 people are affected,often with a poor quality of life.Its high mortality is mainly due to its aggressive growth and tendency to spread.Epithelial-mesenchymal transition(EMT)is a central regulatory hub driving tumor cell migration and invasion by enabling changes in cell characteristics.During EMT,epithelial cells gradually take on mesenchymal traits,gaining mobility and spreading mo re easily.Recent multi-omics studies show that many cancer cells exist in a hybrid or partial-EMT state,which lies between the full epithelial and mesenchymal forms.Cells in this state are especially invasive and metastatic,with high plasticity that promotes tumor progression.This review summarizes the role of partial-EMT in OSCC,with a focus on how it alters the tumor microenvironment(TME),promotes invasion and metastasis,and influences cancer stem cells(CSCs).We also highlight the link between partial-EMT and treatment resistance in OSCC.Based on these insights,we discuss therapeutic strategies targeting partial-EMT to improve outcomes.Targeting partial-EMT may offer promising strategies to enhance treatment effectiveness and improve patient survival and quality of life.
文摘Hepatocellular carcinoma presents with three distinct immune phenotypes,including immune-desert,immune-excluded,and immune-inflamed,indicating various treatment responses and prognostic outcomes.The clinical application of multi-omics parameters is still restricted by the expensive and less accessible assays,although they accurately reflect immune status.A comprehensive evaluation framework based on“easy-to-obtain”multi-model clinical parameters is urgently required,incorporating clinical features to establish baseline patient profiles and disease staging;routine blood tests assessing systemic metabolic and functional status;immune cell subsets quantifying subcluster dynamics;imaging features delineating tumor morphology,spatial configuration,and perilesional anatomical relationships;immunohistochemical markers positioning qualitative and quantitative detection of tumor antigens from the cellular and molecular level.This integrated phenomic approach aims to improve prognostic stratification and clinical decision-making in hepatocellular carcinoma management conveniently and practically.
文摘BACKGROUND Regorafenib is approved as a second-line treatment for advanced hepatocellular carcinoma(HCC),but its comparative efficacy remains under evaluation.AIM To evaluate the efficacy and safety of regorafenib vs other second-line therapies in advanced HCC.METHODS This systematic review and meta-analysis were conducted in accordance with PRISMA guidelines.A comprehensive search of PubMed,EMBASE,Web of Science,and the Cochrane Library was performed on June 6,2025.Studies were included if they reported at least one relevant clinical outcome:Overall survival,progression-free survival,objective response rate,or disease control rate.Data was extracted independently by two reviewers.Quality was assessed using the Cochrane Risk of Bias 2.0 tool for randomized controlled trials and the Newcastle-Ottawa Scale for cohort studies.Pooled effect estimates were calculated using random-or fixed-effects models depending on the degree of heterogeneity.Sensitivity analyses and Egger’s test were performed to evaluate the robustness of the results and potential publication bias.RESULTS Nine studies met inclusion criteria.Regorafenib significantly improved overall survival compared to controls[weighted mean difference=2.54 months;95%confidence interval(CI):0.26-4.81;P<0.05],but no significant benefit was observed for progression-free survival(weighted mean difference=1.04;95%CI:-1.27 to 3.36).The pooled objective response rate showed no overall difference,though regorafenib was inferior to nivolumab in subgroup analysis(odds ratio=0.34;95% CI:0.20-0.58).Disease control rate did not differ significantly.No publication bias was detected.CONCLUSION Regorafenib offers a survival advantage in advanced HCC but does not significantly improve tumor response rates compared to alternative therapies.
文摘BACKGROUND Data comparing the outcomes of hepatocellular carcinoma(HCC)ablation by multibipolar radiofrequency ablation(mbp-RFA)and microwave ablation(MWA)are lacking.This study compares safety and efficacy of the two techniques in treatment-naive HCC.AIM To compare the risk of local tumor progression(LTP)according to the technique;secondary endpoints included technique efficacy rate at one-month,overall survival and major complication rate.METHODS A bi-institutional retrospective analysis of patients undergoing treatment-naive HCC ablation by either technique was performed.Inverse probability of treatment weighting was used to compare the two groups.Mixed effects multivariate Cox regression was applied to identify risk factors for LTP.RESULTS A total of 362 patients(mean age,66.1±6.2 years,308 men)were included,of which 242(323 tumors)treated by mbp-RFA and 120(168 tumors)by MWA.After a median follow-up of 27 months,cumulative LTP was 11.4%after mbp-RFA and 25.2%after MWA.Independent risk factors for LTP at multivariate analysis were MWA(hazard ratio=2.85,P<0.001)and tumor size(hazard ratio=1.08,P<0.001).Two-year LTP-free survival was higher after mbp-RFA than MWA regardless of size(<3 cm:96%vs 87.1%,P<0.01;≥3 cm:87.5%vs 74%,P=0.04).Technique efficacy rate was higher after mbp-RFA(94.1%vs 87.5%,P=0.01).No difference was observed in major complication rate(9.5%vs 7.5%,P=0.59),nor 5-year overall survival(63.6%vs 58.3%,P=0.33).CONCLUSION Mbp-RFA leads to better local tumor control of treatment-naïve HCC than MWA regardless of tumor size and has better primary efficacy,while maintaining a comparable safety profile.

文摘Background:Laparoscopic anatomic hepatectomy of segment 7(LAH-S7)is a challenging surgery.In this study we aimed to investigate surgical and oncological outcomes of various approaches of LAH-S7 in patients with hepatocellular carcinoma(HCC).A particular focus was placed on identifying the Glissonean pedicle of segment 7(G7)and the intersegmental plane.Given the scarcity of comprehensive reviews or comparative studies on clinical outcomes,we also sought to analyze the experiences and advantages associated with different approaches in relation to the anatomic variations of G7.Methods:The clinical data of 124 patients who underwent LAH-S7 for HCC across seven tertiary referral medical centers in China were retrospectively analyzed.Three surgical approaches were categorized based on the procedures used for G7 identification:the indocyanine green(ICG)fluorescence positive staining approach(IFPA),the Glissonean approach(GA),and the hepatic vein-guided approach(HVGA).Subsequently,the postoperative short-term results and oncological outcomes of the three different approaches were compared.Results:The distribution of surgical approaches among the patients was as follows:IFPA in 16(12.9%),GA in 62(50.0%),and HVGA in 46(37.1%)patients.Complications were observed in 27(21.8%)patients.The 1-,3-,and 5-year overall survival(OS)rates were 99.1%,89.2%,and 84.7%,respectively.The 1-,3-,and 5-year recurrence-free survival(RFS)rates were 99.0%,84.7%,and 69.3%,respectively.The OS and RFS rates were comparable across the three approaches.Conclusions:Following a standardized surgical procedure,LAH-S7 is demonstrated to be safe and yields favorable oncological outcomes.Surgeons performing LAH-S7 should select the appropriate surgical approach based on the anatomical characteristics and variations of G7.
文摘Objective:To investigate the correlation between the expression of glucose-6-phosphate dehydrogenase(G6PD)and the clinicopathological characteristics,prognosis and immune cell infiltration of hepatocellular carcinoma(HCC).Methods:The expression of G6PD in liver cancer tissues and normal tissues is extracted from TCGA and GEO databases,validated by immunohistochemistry,and the correlation between G6PD expression and clinical features is analyzed.The clinical significance of G6PD in liver cancer is assessed by Kaplan-Meier,Cox regression,and prognostic line graph models.Functional enrichment analysis is performed by protein-protein interaction(PPI)network,GO/KEGG,GSEA and for G6PD-associated differentially expressed genes(DEGs).TIMER and ssGSEA packages are used to assess the correlation between expression and the level of immune cell infiltration.Results:Analysis of TCGA and GEO datasets revealed that G6PD expression is significantly upregulated in hepatocellular carcinoma tissues(P<0.001).G6PD expression is associated with histological grade,pathological stage,T-stage,vascular infiltration,and AFP level(P<0.05);HCC patients in the low G6PD expression group had longer overall survival and better prognosis compared with the high G6PD expression group(P<0.05).The level of G6PD expression affects the levels of macrophages,dendritic cells,B cells,and follicular helper T cells in the tumor microenvironment.Conclusion:High expression of G6PD is a potential biomarker for poor prognosis of hepatocellular carcinoma,and G6PD may be a target for immunotherapy of HCC.

文摘Atractylodes macrocephala Koidz.(A.macrocephala)is a medicinal and edible plant species belonging to the Compositae family.Its rhizome serves both therapeutic and nutritional purposes in China.This investigation led to the isolation of thirteen novel rearranged 9(8→7)-abeo-eudesmane-type sesquiterpenoid dimers(SDs),atramacronins A-M(1-13),three eudesmane-type SDs,atramacronins N-P(14-16),and two previously identified meroterpenoids,atrachinenin G(17)and atrachineninΙ(18),from Atractylodes macrocephala.Structure elucidation was accomplished through comprehensive spectroscopic analysis and single-crystal X-ray diffraction.Compounds 1,4-7,9,and 10 exhibited notable cytotoxicity against Hep3B,HepG2,and Huh7 cell lines,with half maximal inhibitory concentration(IC_(50))values ranging from 3.71 to 13.99μmol·L^(-1).
文摘This commentary critically appraises the study by Li et al which pioneered the exploration of the triglyceride-glucose(TyG)index as a prognostic marker in hepatitis B virus-related advanced hepatocellular carcinoma patients undergoing combined camrelizumab and lenvatinib therapy.While we acknowledge the study’s clinical relevance in proposing an easily accessible metabolic biomarker,we delve into the mechanistic plausibility linking insulin resistance to immunotherapy response and angiogenic inhibition.We further critically examine the methodological limitations,including the retrospective design,the populationspecific TyG cut-off value,and unaddressed metabolic confounders.We highlight the imperative for future research to validate its utility across diverse etiologies and treatment settings,and to unravel the underlying immunometabolic pathways.

文摘Background:Liver transplantation(LT)provides an option to radically eliminate hepatocellular carcinoma(HCC)on the premise that recipients are thoroughly evaluated for posttransplant tumor recurrence risk before operation.This study aimed to optimize the Milan criteria(MC)by combining circulating prognostic markers,including interleukin-6(IL-6)and alpha-fetoprotein(AFP).Methods:We retrospectively enrolled 449 HCC cases receiving LT in three medical centers in China and divided them into the training cohort(n=254)and the validation cohort(n=195).Cox regression analysis was applied to identify recurrence-related risk factors based on patients’clinical and pathological characteristics,pretransplant plasma IL-6 and AFP levels.The collaborative prediction method was presented in the form of a decision tree.Kaplan-Meier analysis showed the predictive results of independent risk factors and the newly established prediction tree.Results:In the training cohort(n=254),we established a predictive decision tree based on three independent risk factors:pretransplant plasma IL-6(>15 pg/mL),AFP(>60 ng/mL),and the MC(beyond the MC),and named it as MIA(MC-IL-6-AFP)tree.According to the MIA tree,patients beyond the MC but with IL-6≤15 pg/mL and AFP≤60 ng/mL(n=39)had comparable 3-year recurrence-free survival(RFS)rates as patients within the MC(n=121):66.8%vs.74.7%(P=0.520).Likely,in the validation cohort(n=195),the 3-year RFS rates of patients beyond the MC but with IL-6≤15 pg/mL and AFP≤60 ng/mL(n=26)were close to those of patients within the MC(n=87):71.8%vs.76.6%(P=0.660).Conclusions:We proposed that pretransplant plasma IL-6 and AFP were valid prognostic biomarkers for HCC-related LT.The MIA tree could refine the MC by combining IL-6 and AFP and define an extra subset of eligible candidates without significant sacrifice in RFS.
文摘BACKGROUND Sorafenib has been the conventional treatment for advanced hepatocellular carcinoma(HCC)since 2008.While radiological complete responses are extremely rare,improved supportive care and multidisciplinary approaches in clinical practice may explain the recent increase in case reports and retrospective series documenting such responses.CASE SUMMARY This case series describes 3 patients with advanced HCC who achieved durable complete responses using first-line sorafenib therapy,even in the presence of portal vein thrombosis or extrahepatic spread,and highlights the potential for sustained remission in selected patients.Dermatologic toxicity and non-viral etiology may correlate with favorable outcomes;however,reliable predictive biomarkers for sorafenib response are lacking.CONCLUSION Future research into the etiology and molecular differences in HCC is necessary to develop more personalized therapy options.
文摘BACKGROUND The treatment technology of liver cancer is progressing.In addition to traditional surgical resection,combined therapies of immunotherapy based on immune checkpoint inhibitors,chemotherapy,and transcatheter arterial chemoembolization for hepatocellular carcinoma are more and more widely used.Accurate preoperative diagnosis of liver cancer will provide important information for comprehensive treatment and prognosis evaluation of liver cancer.Sonazoidcontrast-enhanced ultrasound is not only helpful for the qualitative diagnosis of liver lesions,but also has great potential in the diagnosis of histological differentiation of liver cancer.AIM To assess the differentiation of hepatocellular carcinoma(HCC)by utilizing the parameters and imaging features of Sonazoid-contrast-enhanced ultrasound(CEUS).METHODS A retrospective analysis was conducted on the CEUS data of 239 lesions through case-control study.These patients received Sonazoid-CEUS within one week before surgery and were confirmed as HCC by postoperative pathology.Within the cases,patients were further categorized into well-differentiated and poorlydifferentiated group.Time-intensity curves of the region of interest in both arterial and Kupffer phases were generated,allowing for the acquisition of quantitative parameters to assess the diagnostic efficacy in distinguishing lesions between these two groups and determining an appropriate cut-off value.RESULTS Univariate analysis showed that the absolute value of enhancement intensity(EIAV),intensity ratio(IR)and intensity difference(ID)in Kupffer phase were statistically different between the groups with different degree(P=0.015,P=0.000,P=0.000).The sensitivity and specificity were 40.2%,82.4%,80.4% and 78.1%,86.9% and 74.5%,respectively,for differentiating HCC lesions with EIAV≥56.384 dB,IR≥1.215 and ID≥9.184 dB.The area under the receiver operating characteristic curve were 0.590,0.877,0.815.There was no significant difference in the parameters of arterial phase,including peak time,initial growth time,rise time and the absolute value of peak intensity of lesions between the two groups(P>0.05).Multivariate analysis showed that the level of alphafetoprotein(AFP)and IR were risk factors for poor differentiation(P=0.001).CONCLUSION Among the parameters of Sonazoid-CEUS,IR in Kupffer phase exhibits superior diagnostic efficacy with high sensitivity and specificity in the diagnose of pathological differentiation of HCC.Combined with preoperative AFP level,a more accurate diagnosis will be obtained.Compared with portal vein phase,Kupffer phase showed the ability to identify HCC lesions more sensitive.These findings hold significant guiding implications and reference value for clinical practice.

文摘Prostatic carcinoma(PCa)has become one of the most common cancers among men worldwide,with both incidence and mortality rates steadily rising.Although current treatments are effective in the early stages of PCa,many cases eventually progress to castration-resistant prostate cancer(CRPC),and led to treatment failure.To develop new therapeutic strategies to ameliorate the survival of PCa patients then has pressed the need on medicinal researchers.Of traditional Chinese medicinal herbs,Angelica gigas Naka(AGN),and its major pyranocoumarins were broadly reported on the effect of anti-PCa.However,existing reviews mainly focus on decursin(D),decursinol angelate(DA),and decursinol(DOH),without fully exploring other coumarins in AGN.Moreover,most reviews discuss general anticancer effects,with limited emphasis on PCa specifically.This review made a comprehensive summary of the coumarin components of AGN,and depicted the anti-PCa effects and mechanisms,giving a solid research support for drug discovery and development.This review also featured pharmacokinetic advantages and therapeutic potential of DOH,in order to suggest possibilities to overcome the in vivo transformation limitations of D and DA,and shed light on CRPC treatment.We also recommend future studies focus on more in vivo evidence,safety and toxicity evaluation,and clinical validation in humans.
文摘For early hepatocellular carcinoma(HCC),curative therapies include surgical excision and radiofrequency ablation.Other treatment modes for advanced HCC involve transarterial chemoembolization.For HCC patients who do not fit the Milan criteria or are waiting for liver transplantation(LT),studies of transarterial radioembolization with Yttrium-90(Y-90)demonstrated that Y-90 may accomplish a good downstaging or bridging effect before LT and can even achieve complete pathological necrosis.The present review discussed Y-90 radioembolization as a local regional treatment option for advanced and unresectable HCC,with a focus on neoadjuvant intervention before LT.

文摘BACKGROUND Rhabdomyosarcoma(RMS)is a type of malignant tumor originating from rhabdomyocytes or mesenchymal cells differentiating into rhabdomyocytes.Hepatic pleomorphic RMS is a rare malignant liver tumor.Hepatic sarcomatoid carcinoma is also a rare epithelial malignant tumor originating from the liver;it is characterized by the coexistence of both carcinomatous and sarcomatoid spindle cell components.CASE SUMMARY This paper reports a special case of an elderly woman whose initial liver puncture biopsy showed pleomorphic RMS.After chemotherapy with the vincristine+doxorubicin+cyclophosphamide regimen,the alpha-fetoprotein level increased significantly.Therefore,a second liver puncture was performed,the pathological result of which was hepatic sarcomatoid carcinoma.Next-generation sequencing revealed MET gene amplification with an average copy number of 9 in the tumor tissue;however,both fluorescence in situ hybridization and immunohistochemical tests were negative for MET amplification.The treatment regimen was adjusted to chemotherapy combined with immunotherapy;however,the disease progressed rapidly,and the overall survival was only 6 months.CONCLUSION By sharing the diagnosis and treatment process of this patient and reviewing the relevant literature,we aim to help clinicians enhance their understanding of two rare diseases,namely pleomorphic RMS and sarcomatoid carcinoma of the liver.
文摘Background:Sarcomatoid carcinoma of the ureter(SCU)is a highly aggressive and relatively uncommon malignant tumor of the urinary tract.Its frequency is quite low,and its prognosis is very bad when compared to other cancers of the urinary system.SCU clinical reports are still hard to come by.MRI and PEI/CT imaging of ureteral sarcomatoid cancer is presented in this case to promote diagnostic awareness and comprehension of the imaging characteristics of this uncommon illness.Method:The patient had ureteral sarcomatoid cancer,which was verified by pathological investigation after ureteroscopic biopsy.The patient’s clinical information,imaging results,surgical outcomes,and pathological findings were gathered.A retrospective study was carried out in combinationwith pertinent national and international literature.Results:An 84-year-old female patient was admitted for“left flank discomfort lasting over one month.”MRI revealed an irregular soft tissue mass in the middle-lower segment of the left ureter.T2-weighted imaging showed an unevenly slightly hyperintense signal.Diffusion-weighted imaging demonstrated restricted diffusion.Contrastenhanced imaging exhibited heterogeneous enhancement.PET/CT demonstrated significantly increased fluorodeoxyglucose metabolism in the mass with secondary left upper urinary tract obstruction.Concurrent findings included a solitary metastatic lesion in hepatic segment S6 and multiple lymph node metastases along the left common iliac and external iliac arteries.Preoperative diagnosis suggested a malignant tumor of the ureter.The patient underwent left nephroureteroscopy with biopsy,and the postoperative pathological diagnosis was ureteral sarcomatoid carcinoma.Conclusion:Ureteral sarcomatoid carcinoma is a rare,highly malignant,and aggressive tumor with nonspecific imaging features,typically presenting as an invasively growing mass.Diagnosis relies on postoperative pathology and immunohistochemical examination.MRI and PET/CT scans are valuable for preoperative localization and characterization,tumor staging,treatment planning,and postoperative follow-up.The prognosis is extremely negative.The main treatment option is radical surgery,although constant monitoring is necessary since early recurrence and metastases are frequent after surgery.

文摘According to the 2024 global cancer data from GLOBOCAN,liver cancer ranks the 6th most common malignancy and the 3rd leading cause of cancer-related mortality worldwide[1].Among these cases,hepatocellular carcinoma(HCC)accounts for approximately 85%−90%[2,3].Its incidence and mortality rates remain persistently high worldwide.However,China has the highest incidence and mortality rates of the disease in the world[4].And the majority of patients are diagnosed at intermediate or advanced stages.Thus,identifying novel tumor biomarkers for early detection and implementing precision therapy has long been a key focus of research.
文摘BACKGROUND Approximately 30%of patients with head and neck cancer experience adverse effects caused by anxiety and depression.Considering the high prevalence,implementing customized interventions to ease adverse emotional states is imperative.AIM To evaluate the efficacy of cognitive behavioral therapy(CBT)-based psychological interventions in improving the psychological well-being and quality of life(QoL)of patients with laryngeal carcinoma.METHODS This study enrolled 120 patients admitted from February 2022 to February 2024.The control group,comprising 50 participants,received standard supportive psychological care,while the research group,consisting 70 participants,underwent CBT-based interventions.Several clinical outcomes were systematically assessed that included postoperative recovery metrics(duration of tracheostomy and nasogastric tube dependence and length of hospitalization),psychological status(Self-Rating Anxiety Scale and Self-Rating Depression Scale),nutritional markers(serum albumin and hemoglobin levels),sleep quality(Self-Rating Scale of Sleep and Athens Insomnia Scale),and QoL(Functional Assessment of Cancer Therapy-Head and Neck).RESULTS The results demonstrated that the research group experienced superior outcomes,with significantly reduced durations of tracheostomy and nasogastric tube dependence,as well as shorter hospital stays,compared with the control group.Additionally,the research group exhibited markedly lower post-intervention Self-Rating Anxiety Scale,Self-Rating Depression Scale,Self-Rating Scale of Sleep,and Athens Insomnia Scale scores,along with minimal but higher change in serum albumin and hemoglobin levels compared with the control group.All five domains of Functional Assessment of Cancer Therapy-Head and Neck showed notable improvements in the research group,exceeding those observed in the control group.CONCLUSION CBT-based psychological support positively affects the mental well-being and QoL of patients with laryngeal carcinoma,highlighting its potential for broader clinical application.

文摘Hepatocellular carcinoma(HCC)remains one of the most prevalent and lethal malignancies worldwide.Long non-coding RNAs(lncRNAs)have emerged as crucial regulators of gene expression and cancer progression,yet the functional diversity of RP11-derived lncRNAs—originally mapped to bacterial artificial chromosome(BAC)clones from the Roswell Park Cancer Institute—has only recently begun to be appreciated.This mini-review aims to systematically synthesize current findings on RP11-derived lncRNAs in HCC,outlining their genomic origins,molecular mechanisms,and biological significance.We highlight their roles in metabolic reprogramming,microRNA network modulation,and tumor progression,as well as their diagnostic and prognostic value in tissue and serum-based analyses.Finally,we discuss therapeutic opportunities and propose future directions to translate RP11-derived lncRNAs into clinically actionable biomarkers and targets for precision liver cancer therapy.

文摘Background:According to the 2022 update of the BCLC strategy,laparoscopic liver resection(LLR)is considered feasible for BCLC stage 0-A hepatocellular carcinoma(HCC)patients with clinically significant portal hypertension(CSPH).However,there is still no research to explore the outcomes of laparoscopic versus open liver resection(OLR)in the specific patients with BCLC stage 0-A HCC and CSPH.Methods:Patients diagnosed with BCLC stage 0-A HCC and CSPH who underwent liver resection at West China Hospital of Sichuan University from February 2018 to December 2022 were analyzed.Demographic characteristics,pathological findings and postoperative outcomes were compared using propensity score matching(PSM).Long-term outcomes after surgery were analyzed using Kaplan-Meier analysis both before and after PSM.Results:A total of 409 patients,including 261 LLRs and 148 OLRs,were enrolled in this study.There were imbalances between the groups in baseline information.After 1:1 PSM,118 patients were included in each group with comparable baseline characteristics.Patients in the LLR group had significantly less intraoperative blood loss compared to those in the OLR group(median 223 vs.318 mL,P<0.001),and fewer postoperative complications(33.9%vs.57.6%,P<0.001),including lower rates of postoperative liver decompensation(16.9%vs.28.0%,P=0.043),postoperative ascites(18.6%vs.31.4%,P=0.024)and pulmonary infections(12.7%vs.29.7%,P=0.001).The long-term follow-up showed that overall survival(P=0.154)and recurrence-free survival(P=0.376)were comparable between the two groups.In subgroup analysis,patients with PLT≤75×10^(9)/L suffered more postoperative liver decompensation(PLD)and ascites than patiens with PLT>75×10^(9)/L.Conclusions:Compared with OLR,LLR had less intraoperative blood loss,fewer postoperative complications and comparable oncological outcomes for patients with BCLC stage 0/A HCC and CSPH.

文摘Background:The regulatory mechanisms governing vasculogenic mimicry(VM)in oral squamous cell carcinoma(OSCC)remain largely undefined.This study aimed to identify critical factors and elucidate the epigenetic mechanisms underlying VM in OSCC.Methods:Bioinformatics analysis was performed utilizing single-cell RNA-seq,bulk RNA-seq,and histone H3 lysine 27 acetylation(H3K27ac)Chromatin Immunoprecipitation(ChIP)-seq data obtained from The Cancer Genome Atlas(TCGA)and Gene Expression Omnibus(GEO)databases.ChIP-qPCR was used to validate the binding of ETS transcription factor ELK4(ELK4)to the dihydrofolate reductase(DHFR)enhancer.In vitro VM formation and invasion of OSCC cells were assessed using Matrigel-based tube formation and Transwell assays,respectively.Results:Elevated expression of VM-related genes predicts unfavorable prognosis in OSCC patients.High-dimensional weighted gene co-expression network analysis(hdWGCNA)identified epithelial subcluster C4 as most strongly associated with VM and metastasis.Three co-expression modules within this subcluster exhibited significant positive correlations with both phenotypic traits.Among the 30 eigengenes from the three modules,DHFR emerged as a key regulator of VM and metastasis.Knockdown or inhibition of DHFR significantly suppressed VM formation and invasion in OSCC cells.Mechanistically,ELK4 activated DHFR transcription through direct binding to its enhancer.DHFR overexpression rescued VM and invasion impairment induced by ELK4 knockdown.Conclusion:DHFR was a pivotal enhancer-regulated gene driving VM and metastasis in OSCC.ELK4 directly binds to DHFR enhancer regions to activate its transcription,thereby promoting these malignant phenotypes.These findings identified the ELK4/DHFR axis as a promising therapeutic target for anti-angiogenic intervention in OSCC.
