PTPN4 and cervical cancer: Analysis of function of the annotated genes in the 161-gene panel, however, indicated that apoptosis-related genes (BNIP3, BCL2L11, TNFSF13, PERP, ATF6, BPTF) and phosphatases (DUSP1, PPP2R5E, PTPN4) were underexpressed whereas genes involved in transcriptional activation (ATF2, GTF3C1, TFE3, MCRS1) and signaling, and migration of cells (MAPRE3, PAK7, PIK3R1) were overexpressed in advanced stage as compared to early-stage cervical cancer.
