MARCHF9 and colorectal carcinoma: To evaluate the prognostic significance of MARCHF9 expression in CRC, we conducted Kaplan–Meier survival analyses using data from both the Cancer Genome Atlas (TCGA) cohort and a mixed cohort that combined TCGA and Gene Expression Omnibus (GEO) data (GSE12945, GSE13294, GSE14333, GSE143985, GSE17538, GSE18088, GSE26682, GSE30540, GSE31595, GSE33114, GSE34489, GSE37892, GSE38832, GSE39582, GSE41258, and GSE92921) [14].
