Whereas, for HIF-2α-mediated EMT, researches in this area remained scarce.
WebLW 6 (CAY10585, AC1-001) is a hypoxia-inducible factor 1 (HIF) inhibitor which potently inhibits HIF-1α accumulation by degrading HIF-1α without affecting the HIF-1a mRNA levels during hypoxia. LW6 inhibits HIF and MDH2 expression with IC50 values of 4.4 and 6.3 μM, respectively. Sci Adv, 2024, 9 (1):eabo7555.

WebIntroduction. HIF-1, a member of a family of hypoxia-inducible transcription factors (HIFs), was discovered in 1992, during studies on the oxygen-dependent regulation of erythropoietin expression. 1 It is a heterodimer containing a novel α subunit (HIF-1α) and a previously characterized β subunit (HIF-1β or aryl hydrocarbon receptor nuclear translocator [ARNT]).
