Abstract
Background
The CDH1 gene promoter variant C > A (rs16260) is associated with downregulation of E-cadherin, which compromises epithelial integrity and has been linked to poor prognosis in various cancers. This study investigates the association of the CDH1 C > A variant with gene expression and its potential as a prognostic biomarker for cervical cancer in an Indian population.
Methods
This case-control study involved 107 cervical cancer patients and 96 age-matched healthy controls. Genotyping of the CDH1 C > A (rs16260) variant was performed using PCR-RFLP, and gene expression was analyzed through qPCR. Kaplan-Meier and Cox regression analyses were used to correlate genotypes and gene expression with treatment response and survival outcomes. Statistical analysis was conducted using QUANTO (v.1.2), GraphPad Prism (v. 10), SPSS (v. 25).
Results
The CA and CA + AA genotypes of the CDH1 variant were significantly associated with cervical cancer risk (P = 0.011 and P = 0.004, respectively). CDH1 gene expression was significantly downregulated in cervical cancer patients compared to controls (P = 0.023). While the CA genotype was protective against recurrence and treatment toxicity (P < 0.001 and P = 0.050, respectively), the CC genotype was linked to increased toxicity and recurrence. CA genotype shows a trend toward better overall survival (median 27 vs. 19 months; HR < 1), though not statistically significant (P = 0.079).
Conclusion
The CDH1 C > A (rs16260) variant may be a prognostic biomarker to predict toxicity and recurrence of cervical cancer, with implications for personalized treatment strategies. However, further studies in larger, more diverse cohorts are necessary to validate these findings.

期刊介绍:
Gene Reports publishes papers that focus on the regulation, expression, function and evolution of genes in all biological contexts, including all prokaryotic and eukaryotic organisms, as well as viruses. Gene Reports strives to be a very diverse journal and topics in all fields will be considered for publication. Although not limited to the following, some general topics include: DNA Organization, Replication & Evolution -Focus on genomic DNA (chromosomal organization, comparative genomics, DNA replication, DNA repair, mobile DNA, mitochondrial DNA, chloroplast DNA). Expression & Function - Focus on functional RNAs (microRNAs, tRNAs, rRNAs, mRNA splicing, alternative polyadenylation) Regulation - Focus on processes that mediate gene-read out (epigenetics, chromatin, histone code, transcription, translation, protein degradation). Cell Signaling - Focus on mechanisms that control information flow into the nucleus to control gene expression (kinase and phosphatase pathways controlled by extra-cellular ligands, Wnt, Notch, TGFbeta/BMPs, FGFs, IGFs etc.) Profiling of gene expression and genetic variation - Focus on high throughput approaches (e.g., DeepSeq, ChIP-Seq, Affymetrix microarrays, proteomics) that define gene regulatory circuitry, molecular pathways and protein/protein networks. Genetics - Focus on development in model organisms (e.g., mouse, frog, fruit fly, worm), human genetic variation, population genetics, as well as agricultural and veterinary genetics. Molecular Pathology & Regenerative Medicine - Focus on the deregulation of molecular processes in human diseases and mechanisms supporting regeneration of tissues through pluripotent or multipotent stem cells.
