EXPRESSION OF COL6A1 IN SARCOMA TISSUE AND ITS SIGNIFICANCE

Objective To investigate the expression of COL6A1 in sarcoma tissue and its significance based on bioinformatics analysis. Methods The GEO database was used to download the GSE16088, GSE21122, and GSE49972 datasets to analyze the expression level of COL6A1-3. The Kaplan-Meier survival curves were used to analyze the impact of the expression level of COL6A1-3 on the prognosis of patients with sarcoma. A Spearman correlation analysis was performed using GSVA package to investigate the correlation between the expression level of COL6A1 and immune cell infiltration. The LinkedOmics database was used to analyze the genes co-expressed with COL6A1, and the ggstatsplot package of R software was used to investigate the correlation between COL6A1 and COL6A2. The ClusterProfiler package of R software was used to perform GO functional enrichment analysis and KEGG pathway analysis of the genes co-expressed with COL6A1. The GSEA analysis was used to investigate the important kinase, miRNA, and transcription factor targets
