PMID Text
24703425 Hepatic OSTalpha-OSTbeta expression is induced by hypoxia.
24264050 OSTbeta is a target of RARalpha-mediated (by binding to DR5 response element) gene regulation pathways
22535958 Ostbeta is required for both proper trafficking of Ostalpha and formation of the functional transport unit, and identify specific residues of Ostbeta critical for these processes.
21691099 The present report summarizes the evidence for a pleiotropic role of Ostalpha-Ostbeta in different tissues.
20649839 OSTbeta is localized to steroidogenic cells of the brain and adrenal gland, and it modulates DHEA/DHEAS homeostasis
18847488 interaction of solute transporter beta with human organic solute transporter alpha.
18469300 The mRNA expression of OSTalpha-OSTbeta was significantly reduced (OSTalpha: 3.3-fold, P = 0.006; OSTbeta: 2.6-fold, P = 0.03) in normal-weight but not overweight gallstone carriers
17332473 Demonstrate association of OST-alpha and OST-beta to determine trafficking to plasma membrane and activity.
16423920 These results indicate that expression of Ostalpha and Ostbeta are highly regulated in response to cholestasis and that this response is dependent on the FXR bile acid receptor.
16317684 the selective localization of OSTalpha and OSTbeta to the basolateral plasma membrane of epithelial cells responsible for bile acid and sterol reabsorption.
16269519 OSTalpha/OSTbeta expression is induced by bile acids through ligand-dependent transactivation of both OST genes by the nuclear bile acid receptor/farnesoid X receptor (FXR).
16251721 overexpression of human OSTalpha and OSTbeta facilitated the uptake of conjugated chenodeoxycholate and the activation of FXR target genes
12719432 OSTbeta has roles in biological transport and is widely expressed in human tissues
