Abstract:
Objective:To explore the function of LIM and calponin homology domains 1(LIMCH1)in the development and progression of oral squamous cell carcinoma(OSCC),along with their potential clinical applications.Methods:By utilizing transcriptome sequencing data from two groups of oral squa-mous cell carcinoma patients,along with bioinformatics analytical techniques such as Gene Ontology(GO)and gene co-expression networks,we identified genes that might play a pivotal role in the patho-genesis of oral squamous cell carcinoma.We employed real-time quantitative PCR and Western blotting to validate the expression patterns of these genes across twelve patient tissue samples.Furthermore,we con-ducted CCK-8 assays,flow cytometry analyses,and scratch wound healing assays to assess the impact of key genes on the biological behaviors of both the Ca127 oral squamous cell carcinoma cell line and the po-tentially malignant DOK oral lesion cell line.Additionally,we examined correlations between these key genes and clinical disease parameters in 214 oral squamous cell carcinoma patients using The Cancer Ge-nome Atlas(TCGA)data;gene set enrichment analysis(GSEA)analysis results were also incorporated to enhance our findings from real-time quantitative PCR and Western blotting regarding potential mecha-nisms underlying the action of these key genes.Results:The integrated analysis of sequencing data and bioinformatics revealed that LIMCH1 exhibited significantly reduced mRNA(P＜0.001)and protein levels(P＜0.01)in the oral squamous cell carcinoma tissues compared with normal control tissues.In the Ca127 cells,the low LIMCH1 level group demonstrated a larger wound healing area within 24 hours than the control group(P＜0.01),enhanced proliferation capacity over 72 hours relative to the control group(P＜0.01),and an increased apoptosis rate within 24 hours compared with the high expression group(P＜0.05).However,no significant differences were observed between the low and high level groups in DOK cells.Furthermore,it was determined that low LIMCH1 level correlated with poor prognosis in the patients(P=0.013)and a higher lymph node metastasis rate(P＜0.05).Investigations into the poten-tial mechanisms of action indicated that LIMCH1 did not influence the onset or progression of oral squa-mous cell carcinoma via the epithelial-mesenchymal transition pathway.Conclusion:LIMCH1 level may function as a promising biomarker to aid in the prognostic assessment of oral squamous cell carcinoma;however,its precise mechanistic role requires further investigation.
