COL5A1 and ovarian cancer: 7 of the 41 genes have significant associations with ovarian cancer patient survival analyzed from TCGA, and their Kaplan-Meier survival plots are shown in Figure 4F. While the expression of ALDH1A3, COL5A1, CPA4, GLIPR1, HABP4, MARCKS and PYGB are unfavorably associated with patient survival, TAP1 and STAT1 expression significantly associated with improved overall survival.
