Abstract:Sickle cell anemia (SCA) is associated with an increased hypoxic response from anemia and vaso-occlusion-impaired tissue perfusion. The effects of hypoxia are mediated by hypoxia transcription factors (HIFs). Chuvash erythrocytosis (CE) is an inherited condition due to homozygosity for the missense mutation in VHL gene (VHLR200W) that impairs interactions of VHL with HIF-α subunits, thereby augmenting transcription of HIF-regulated genes. CE and SCA share increased expression of erythropoietin (EPO) and other … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
