[Objectives]To distinguish loquat flesh color,thereby guiding early-age selection in loquat hybrid progeny.[Methods]Molecular markers based on the phytoene synthase gene(PSY)of loquat were applied to a hybrid progeny population derived from a cross between‘Zaozhong 6’and a local wild white-fleshed loquat resource‘DB1’.[Results]Among the 49 hybrid progeny,24 were identified as white-fleshed loquat resources and 25 as yellow-fleshed loquat resources.[Conclusions]The molecular marker of the PSY gene can effectively distinguish loquat flesh color and is of significant importance for guiding early-age selection in loquat hybrid breeding. 展开更多

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. 展开更多

Stichopus chloronotus is a tropical sea cucumber with facultative asexual reproduction in the Indo-Western Pacific,yet its wild populations are decreasing due to extensive harvesting.Understanding the species’genetic characteristics is essential for effective management and conservation.To develop novel microsatellite markers and assess the genetic diversity,clonality,and genetic structure of eight populations of S.chloronotus in the South China Sea,193 individuals from eight populations across Wuzhizhou and Fenjiezhou(Boundary)islands were analyzed using nine newly developed microsatellite markers and five previously established markers.RNA-Seq was employed to obtained 62662 unigenes and identified 16926 microsatellite loci.Fourteen polymorphic microsatellite loci were developed,of which 11 were highly polymorphic(polymorphic information content>0.5).The number of alleles(N_(a))ranged from 3 to 6 per locus,and the average Shannon diversity index(I)was 1.107.All the populations exhibited asexual reproduction,with regional variations in reproductive modes.Asexual reproduction was predominant in the northwestern Wuzhizhou Island population(SY 7)and the Fenjiezhou Island population(LS 8),where four and five predominant clones represented more than 89%of the individuals,which led to reduced genetic diversity.Overall,genetic diversity was moderately low,with significant genetic differentiation among populations(F_(ST)=0.33;P<0.001),suggesting limited gene flow(the number of migrants(N_(m))<1).These findings highlight the role of reproductive strategies in shaping fine-scale genetic differentiation in S.chloronotus.The limited recruitment success of sexually produced larvae and habitat heterogeneity likely constrain clone dispersal,contributing to distinct genetic restructuring.This study provided key insights into the interplay between reproductive strategies and genetic patterns in sea cucumbers,offering a scientific basis for targeted conservation efforts. 展开更多

Emerging and powerful genome editing tools,particularly CRISPR/Cas9,are facilitating functional genomics research and accelerating crop improvement(Jiang et al.2021;Cao et al.2023;Chen C et al.2023;Liu et al.2023a).However,the detection and screening of transgenic lines remain major bottlenecks,being time-consuming,labor-intensive,and inefficient during transformation and subsequent mutation identification.A simple and efficient visual marker system plays a critical role in addressing these challenges.Recent studies demonstrated that the GmW1 and RUBY reporter systems were used to obtain visual transgenic soybean(Glycine max) plants(Chen L et al.2023;Chen et al.2024). 展开更多

Peel color is an important appearance quality of melons that significantly affects consumer preferences.In this study,a near-isogenic line NIL-G(dark green peel)was generated from B8(grey-green peel)and B15(white peel).The F_2 population constructed by crossing NIL-G and B15 was used to study the inheritance pattern of peel color,and bulked-segregant analysis sequencing(BSA-seq)was employed to identify the interval in which the target gene was located.Genetic analysis showed that a dominant gene controls the dark green peel trait at maturity.BSAseq and molecular markers were used to localize the candidate gene in a 263.7 kb interval of chromosome 4,which contained the CmAPRR2 gene with known functions.Moreover,allelic sequence analysis revealed four SNP variations of the CmAPRR2 gene in B15,of which SNP.G614331A was located at the junction of the 6th exon and 6th intron.The G-to-A mutation caused alternative splicing of the transcript of CmAPRR2 in B15,generating two transcripts(CmAPRR2-A and CmAPRR2-B)with premature termination codons.Furthermore,the Kompetitive Allele Specific PCR(KASP)marker,APRR2-G/A,was developed based on this SNP and shown to co-segregate with the peel color phenotype in the F_(2) population.Compared to white-peel B15,the expression level of CmAPRR2 in dark green peel NIL-G was higher at each growth stage.Therefore,CmAPRR2 may be the key gene controlling the fruit color of melons.This study identified a novel allelic variant of CmAPRR2 that leads to white peel formation in mature melons.We also provides a theoretical basis for further research on the gene regulatory mechanism of melon peel colors,which promotes using molecular marker-assisted selection to modify melon peel colors in the future. 展开更多

Chinese chestnut is an important economic forest tree species with enormous application value in the wood,medical,and chemical industries.Currently,the limited genome-wide SSR molecular marker information on chestnut resources significantly restricts research on the genetic diversity and identification of chestnut resources.To address this issue,we used GMATA to screen simple sequence repeat(SSR)markers throughout the Chinese chestnut genome.A total of 312,302 molecular markers were obtained with a density of 434.38 Mb-1.Subsequently,all SSR markers were examined for polymorphism using the Hip STR program and 138,208 polymorphic loci were ultimately obtained.To verify the capability of the developed SSR for identification,we randomly selected 36 markers on 12 chromosomes to construct fingerprint maps of 96 ancient Chinese chestnut resources from the Yanshan Mountains.The results showed that only six pairs of primers were required to create a unique DNA fingerprint of the tested ancient trees,showing that the developed markers have good potential for identification.We then evaluated the inter-specific universality and polymorphism of these markers using 91 Castanea plants of three different species.The molecular markers amplified 94%of the interspecies with a polymorphic information content(PIC)value of 0.859.Cluster analysis revealed that the resources can be well differentiated using these developed markers,and these markers can be widely used to identify interspecific boundaries.The results of this study proved that the developed molecular markers have the potential for assessing genotypic diversity,which can provide references for genetic diversity research,variety identification,kinship analysis,the selection of good products,and the construction of core germplasm resources of chestnut and even chestnut plants.Also these markers provide a solid foundation for the molecular design of hybrids,improved breeding and development of germplasm resources. 展开更多

BACKGROUND The deleterious effects of surgical trauma and subsequent postoperative complications pose significant challenges to the smooth recovery of patients after gastric cancer(GC)resection despite the substantial curative benefits provided by surgical interventions for GC.Hence,the investigation of more optimal and efficacious treatment approaches has become an urgent necessity in the medical community.AIM To investigate the association of Sijunzi decoction plus chemotherapy with the gastrointestinal function and serum markers of patients after GC surgery.METHODS This study included patients who underwent GC surgery from June 2022 to February 2024.The control group included 45 patients who received chemotherapy(oxaliplatin+calcium folinate+5-fluorouracil),whereas the research group consisted of 54 patients who received Sijunzi decoction therapy in addition to the treatment administered in the control group.Comparative analyses were conducted from the following perspectives:Gastrointestinal function(defecation time,intestinal gas discharge time,and hospitalization time),serum markers[carcinoembryonic antigen(CEA),carbohydrate antigen(CA)125,and CA199],nutritional indicators total protein(TP)and transferrin(TRF),traditional Chinese medicine(TCM)syndrome score,and grades Ⅲ–Ⅳ adverse events(gastrointestinal reactions,renal/liver function impairment,and myelosuppression).RESULTS The two groups demonstrated similar defecation time(P>0.05),but the intestinal gas discharge time and hospitalization time were significantly shortened in the research group(P<0.05).Further,the research group exhibited significant CEA,CA125,and CA199 reductions after treatment,which were lower compared to the control group,as well as notable increases in TP and TRF that were statistically higher than the control group(all P<0.05).Furthermore,the research group demonstrated an evident decrease in TCM syndrome scores in areas,such as poor appetite,epigastric distension and pain,fatigue and weakness(P<0.01),and abdominal distension after eating,which are notably lower than those in the control group(P<0.01),with a comparable incidence of grades Ⅲ-Ⅳ adverse events(P>0.05).CONCLUSION Our research results indicate that Sijunzi decoction plus chemotherapy exerts a good rehabilitation-promoting effect on gastrointestinal function in patients after GC surgery and significantly downregulates abnormally increased CEA,CA125,and CA199 levels. 展开更多

BACKGROUND An increasing number of studies to date have found preoperative magnetic resonance imaging(MRI)features valuable in predicting the prognosis of rectal cancer(RC).However,research is still lacking on the correlation between preoperative MRI features and the risk of recurrence after radical resection of RC,urgently necessitating further in-depth exploration.AIM To investigate the correlation between preoperative MRI parameters and the risk of recurrence after radical resection of RC to provide an effective tool for predicting postoperative recurrence.METHODS The data of 90 patients who were diagnosed with RC by surgical pathology and underwent radical surgical resection at the Second Affiliated Hospital of Bengbu Medical University between May 2020 and December 2023 were collected through retrospective analysis.General demographic data,MRI data,and tumor markers levels were collected.According to the reviewed data of patients six months after surgery,the clinicians comprehensively assessed the recurrence risk and divided the patients into high recurrence risk(37 cases)and low recurrence risk(53 cases)groups.Independent sample t-test andχ2 test were used to analyze differences between the two groups.A logistic regression model was used to explore the risk factors of the high recurrence risk group,and a clinical prediction model was constructed.The clinical prediction model is presented in the form of a nomogram.The receiver operating characteristic curve,Hosmer-Lemeshow goodness of fit test,calibration curve,and decision curve analysis were used to evaluate the efficacy of the clinical prediction model.RESULTS The detection of positive extramural vascular invasion through preoperative MRI[odds ratio(OR)=4.29,P=0.045],along with elevated carcinoembryonic antigen(OR=1.08,P=0.041),carbohydrate antigen 125(OR=1.19,P=0.034),and carbohydrate antigen 199(OR=1.27,P<0.001)levels,are independent risk factors for increased postoperative recurrence risk in patients with RC.Furthermore,there was a correlation between magnetic resonance based T staging,magnetic resonance based N staging,and circumferential resection margin results determined by MRI and the postoperative recurrence risk.Additionally,when extramural vascular invasion was integrated with tumor markers,the resulting clinical prediction model more effectively identified patients at high risk for postoperative recurrence,thereby providing robust support for clinical decision-making.CONCLUSION The results of this study indicate that preoperative MRI detection is of great importance for predicting the risk of postoperative recurrence in patients with RC.Monitoring these markers helps clinicians identify patients at high risk,allowing for more aggressive treatment and monitoring strategies to improve patient outcomes. 展开更多
