文摘Background Neuroendocrine prostate cancer(NEPC)is an aggressive subtype of castration-resistant prostate cancer(CRPC)that is typically resistant to nearly all current therapies.Methods In this study,single-cell RNA sequencing(scRNA-seq)and bioinformatic analysis identified centrosomal protein 55(CEP55)as a critical factor in the transformation from hormone-sensitive prostate cancer(HSPC)to CRPC and,ultimately to,NEPC.Results Subsequent bioinformatics analyses and clinical sample validation showed that CEP55 is significantly upregulated in NEPC tissues relative to HSPC and CRPC.Furthermore,while CEP55 show no significant association with the immune microenvironment or cancer-associated fibroblasts(CAFs),our findings indicated that it directly mediates the plasticity of prostate cancer cells,thereby driving NEPC progression.Specifically,in vivo and in vitro experiments confirmed that CEP55 enhances cell proliferation,migration,invasion and the expression of NEPC biomarkers in prostate cancer.Importantly,although cisplatin is the primary treatment for NEPC clinically,CEP55 has been shown to regulate cisplatin resistance through the phosphorylation of cyclin-dependent kinase 1(CDK1)at the tyrosine 15(Tyr15)site.Conclusions In summary,our study identifies a key gene that influences the neuroendocrine differentiation process in prostate cancer,suggesting its potential as an important therapeutic target.

文摘Lung cancer is the most common but fatal malignant tumor worldwide.Patients with lung cancer experienced a relatively low 5-year overall survival rate,and issues such as metastasis and drug resistance remain prominent challenges in its clinical management.Neddylation,a novel type of post-translational modification,was overactivated in lung cancer and was closely associated with its occurrence,development,metastasis,and drug resistance.This review systematically summarizes the biological process of neddylation and deeply explores the latest research progress on how neddylation affects lung cancer cell proliferation,metastasis,and drug resistance mechanisms,with a focus on its regulation of key molecules such as Cullin-RING E3 ligases and the SCCRO family.Meanwhile,it concludes the current advances in potential therapeutic agents targeting neddylation-related targets,including small-molecule compounds(such as Pevonedistat)and natural extracts(such as arctigenin).Finally,the review prospectively evaluates the application potential and questions requiring further exploration of neddylation in lung cancer treatment.In conclusion,we aim to systematically summarize the biological process of neddylation,critically explore its roles in lung cancer proliferation,metastasis,and drug resistance,and evaluate the therapeutic potential of neddylation-targeting agents.

文摘BACKGROUND Gastric cancer(GC)is one of the most common malignant tumors of the digestive system worldwide,the prognosis of patients with advanced GC remains poor.AIM To evaluate the combined expression characteristics of cancer stem cell markers CD24 and CD133 in GC pathological tissues,and to explore their association with patients’clinicopathological parameters and postoperative survival outcomes.METHODS A total of 304 GC patients who underwent surgical treatment in our hospital from January 2018 to January 2020 were retrospectively included.Immunohistochemistry was used to detect the protein expression of CD24 and CD133 in tumor tissues,adjacent tissues,and normal gastric mucosa tissues.Based on staining intensity and the proportion of positive cells,expression levels were classified into low and high expression,while clinicopathological parameters were recorded.χ2 test was used to evaluate the correlation between expression and categorical variables,Spearman rank correlation analysis was performed to assess the correlation between the expression intensities of the two markers,and multivariate regression models were applied to identify independent risk factors influencing co-expression.Kaplan-Meier survival curves and Log-rank test were used to compare survival differences among groups with different expression patterns.RESULTS Among the 304 patients,155 cases(50.99%)were CD24 positive,including 91 low-expression and 64 highexpression;133 cases(43.75%)were CD133 positive,including 81 low-expression and 52 high-expression.There were 74 cases(24.34%)with double positivity and 81 cases(26.64%)with double negativity.Compared with tumor tissues,the positive rates of CD24 and CD133 in normal gastric tissues and adjacent tissues were significantly lower(P<0.05).Univariate analysis showed that co-expression of CD24 and CD133 in GC tissues was significantly correlated with tumor size,Lauren classification,T stage,N stage,and vascular invasion(P<0.05),but not with patient age,gender,tumor site,World Health Organization histological classification,or M stage(P>0.05).Further multivariate regression analysis suggested that tumor size,T stage,N stage,and vascular invasion were independent risk factors promoting CD24 and CD133 double positivity.Spearman rank correlation analysis indicated a moderate positive correlation between their expression intensities(r=0.420,P<0.001).During follow-up,29 of 304 patients were lost(loss rate 9.54%);146 deaths occurred.According to expression combination,there were 89 cases of CD24 single positivity(39 deaths),68 cases of CD133 single positivity(31 deaths),81 cases of double negativity(25 deaths),and 66 cases of double positivity(51 deaths).Log-rank test showed significant differences in overall survival among the four groups(χ2=20.89,P<0.001),with CD24+/CD133+group showing the worst prognosis.CONCLUSION CD24 and CD133 exhibit high positive detection rates in GC tissues,and their co-positivity is closely associated with tumor stage progression and significantly indicates unfavorable survival outcomes.The co-expression of CD24/CD133 may reflect higher aggressiveness and metastatic potential of GC,serving as a potential prognostic marker and a direction for targeted therapeutic strategies.However,as this is a single-center retrospective study with limitations such as patient loss to follow-up and sample size,further prospective,multicenter,and mechanistic studies are required to validate its clinical applicability and biological role.
文摘Colorectal cancer remains one of the leading causes of morbidity and mortality worldwide.Despite notable advances in early detection and therapeutic strategies,the molecular mechanisms underlying tumor survival,chemotherapy resistance,and metastasis are not yet fully understood.MicroRNAs(miRNAs)have emerged as pivotal regulators of cancer development,as they modulate gene expression and orchestrate key signaling pathways.However,the epigenetic mechanisms that control miRNA expression and their downstream gene targets remain largely unclear.In this review,we highlight the critical role of the colorectal cancer microenvironment in influencing miRNA expression and discuss how this regulation contributes to tumorigenesis.A better understanding of these processes may lead to the identification of novel therapeutic targets and strategies to prevent recurrence.

文摘Breast cancer(BC)remains the most frequently diagnosed malignancy worldwide,with an estimated 2.3 million new cases and approximately 685,000 deaths reported in 2020.Forecasts suggest a substantial rise in global incidence,with new annual cases projected to reach 3.2 million by 2050,representing a 39%increase.Additionally,BC is expected to account for approximately 7.7%of the anticipated$25.2 trillion global economic burden associated with cancer by 2050.These trends underscore an urgent need for affordable,widely accessible and effective therapeutic strategies,particularly in low-and middle-income countries.Statins,commonly prescribed for the treatment of hypercholesterolaemia via inhibition of 3-hydroxy-3-methylglutaryl-coenzyme A(HMG-CoA)reductase,have garnered increasing interest for their potential anticancer properties.This review focuses on the mechanistic underpinnings and therapeutic implications of statin use,particularly simvastatin,in the context of BC.Statins exert their primary effect through inhibition of the mevalonate pathway,which is crucial for cholesterol and isoprenoid biosynthesis.Disruption of this pathway impairs the prenylation of key signalling proteins,including members of the Ras and Rho GTPase families,which are essential for cancer cell proliferation,survival and metastasis.Preclinical evidence has demonstrated that simvastatin can induce tumour cell apoptosis,arrest cell-cycle progression and inhibit oncogenic signalling pathways.These effects have been particularly pronounced in hormone receptor-negative and triple-negative breast cancer(TNBC)subtypes,which are often associated with poor prognosis and limited treatment options.Epidemiological and observational studies further support a potential association between statin use and reduced BC recurrence and mortality.Nevertheless,robust evidence from randomised controlled trials remains limited,and further investigation is required to establish causality and define optimal therapeutic regimens.Given their well-established safety profile,global accessibility and pleiotropic effects,statins,especially simvastatin,represent a promising class of repurposed drugs in the adjuvant treatment of BC.This review synthesises evidence from the past two decades,highlighting the need for continued clinical research to validate and optimise the use of statins as adjunctive agents in BC therapy.

文摘Objective:This study aimed to evaluate the associations of baseline income,cumulative income exposure,and income volatility with the incidence of pancreatic and biliary tract cancers in a nationwide Korean cohort.Methods:We analyzed 3,361,091 adults aged 30-65 years who underwent the 2012 National Health Insurance Service(NHIS)health screening.Income level was derived from insurance premium data assessed over the five years preceding baseline(2008-2012)and categorized into baseline income quartiles,cumulative exposure to low or high income,and income volatility based on annual percentage changes.Incident pancreatic and biliary tract cancers were identified using diagnostic codes and the copayment reduction registry.Associations were evaluated using Cox proportional hazards models with adjustment for demographic,lifestyle,and clinical covariates,and cumulative incidence was compared using Kaplan-Meier curves.Results:During a median follow-up of 9.6 years,14,469 pancreatic cancers and 6,647 biliary tract cancers were newly diagnosed.Lower baseline income was associated with a higher risk of pancreatic and biliary tract cancers,whereas sustained high-income exposure was associated with reduced risk.Cumulative low-income exposure showed a positive linear trend with pancreatic cancer incidence.Income volatility was modestly associated with pancreatic cancer and was positively associated with biliary tract cancer in the fully adjusted model.These associations were generally consistent across subgroups,with a stronger inverse association between prolonged high-income exposure and pancreatic cancer among individuals without diabetes.Conclusions:Income level and income stability were significantly associated with the incidence of pancreatic and biliary tract cancers.Lower baseline income was associated with higher risk,whereas sustained high-income exposure was protective.Income volatility was associated with increased cancer risk,particularly for biliary tract cancer.These findings highlight the importance of incorporating income dynamics into cancer prevention strategies and addressing socioeconomic instability among vulnerable populations.
