Hepatocyte nuclear factor (HNF)-1β and its physiological importance in endometriosis

Hepatocyte nuclear factor-1β (HNF-1β) promotes glucose uptake and glycolytic activity in ovarian clear cell carcinoma.

Ovarian clear cell carcinoma (OCCC) is a morphologically and biologically distinct subtype of ovarian carcinomas that often arises in ovarian endometriosis. We previously reported that a unique carcinogenic environment, especially iron-induced oxidative stress in endometriotic cysts may promote development of OCCC. We also identified a gene expression profile characteristic of OCCC (the "OCCC s...

Hepatocyte nuclear factor-1ß(HNF-1ß) in human urogenital organs: Its expression and role in embryogenesis

often involved in tumorigenesis. Recent exhaustive cDNA microarray analyses in human neoplasms expanded knowledge of such molecules. Hepatocyte nuclear factor-1ß (HNF-1ß) is a homeobox transcription factor that functions as a homodimer or heterodimer with HNF-1α. In contrast to HNF-1α, HNF-1ß is very weakly expressed in the liver and is commonly expressed in the kidneys. During human embryonic ...

Orphan nuclear receptor SHP interacts with and represses hepatocyte nuclear factor-6 (HNF-6) transactivation.

SHP (small heterodimer partner; NR0B2) is an atypical orphan NR (nuclear receptor) that functions as a transcriptional co-repressor by interacting with a diverse set of NRs and transcriptional factors. HNF-6 (hepatocyte nuclear factor-6) is a key regulatory factor in pancreatic development, endocrine differentiation and the formation of the biliary tract, as well as glucose metabolism. In this ...

Nuclear importin α and its physiological importance

Importin α is recognized as a classical nuclear localization signal (cNLS) receptor which mediates nucleocytoplasmic transport. However, it rapidly accumulates in the nucleus in response to cellular stresses, including oxidative stress, causing a blockade of the classical nuclear import pathway. We set out to determine whether importin α performs roles in the nucleus after cellular exposure to ...
