PG - 615-621 LID - S0006-291X(16)31651-5 [pii] LID - 10.1016/j.bbrc.2016.09.166 [doi] AB - Prostate transmembrane protein, androgen induced 1 (PMEPA1) is highly expressed in various solid tumors and is known to play important roles in the transforming growth factor-beta (TGF-beta) signaling pathway. Here, we demonstrate a novel relationship between PMEPA1 and hypoxia, a common microenvironmental stress condition in solid tumors. We showed that induction of PMEPA1 expression occurred during hypoxia in a manner dependent on both TGF-beta signaling and hypoxia-inducible factor-1 (HIF-1) pathways. Furthermore, overexpression and knockdown experiments revealed that PMEPA1 enhanced HIF-1 transcription activity. Bioinformatics analyses of PMEPA1-correlated genes using a gene expression database in clinical settings showed significant enrichment of gene sets defined by TGF-beta and hypoxia and these two signaling pathways-related angiogenesis and epithelial-mesenchymal transition in many types of solid tumors. Collectively, our findings indicated that PMEPA1 participates in TGF-beta- and hypoxia-regulated gene expression networks in solid tumors and thereby may contribute to tumor progression.
