ST6GALNAC1 is highly expressed in ovarian cancer and mediates the Akt signaling pathway. a Comparison of the differentially expressed genes in GSE14407, GSE18520, GSE38666, and GSE66957, and 5 intersecting differentially expressed genes; b the relationship between ITLN1, GADL1, CD24, FOLR1, ST6GALNAC1, and ovarian cancer. Relationship between GADL1 and ST6GALNAC1 and ovarian cancer is not shown in the figure; c the interaction network of differentially expressed genes and disease genes in ovarian cancer, red diamonds represented differentially expressed genes, and purple circles represented disease genes; d, e the heat maps of the first 50 differentially expressed genes in GSE14407 and GSE38666. The abscissa indicated the sample number, the ordinate indicated the differentially expressed genes, and the upper right histogram was the color scale. Each rectangle corresponded to a sample expression value; f, g the expression changes of ST6GALNAC1 in GSE18520 and GSE66957; h KEGG enrichment analysis of ovarian cancer differentially expressed genes and disease genes
