FOLH1 and carcinoma: Immunohistochemistry was used to investigate differentially expressed hypoxia-associated molecules (hypoxia-inducible factor-1 subunit alpha [HIF-1α], forkhead box O1, prostate-specific membrane antigen, signal transducer and activator of transcription 3 [STAT3], hepatocyte nuclear factor 1β [HNF-1β], aquaporin-3, and vimentin [VIM]) between these carcinomas because of the reported association between CC and ischemia.
