Hif2α是什么
WebHIF2α mRNA expression is highest in the lung, a tissue with high oxygen tensions that is unlikely to allow for HIF2α stabilization (Fig. S1). Because HIF2α expression is correlated with the expression of PGC-1α in many tissues, we asked whether PGC-1α could reg-ulate the expression of HIF2α in a variety of cell types. As pre- Web8 de fev. de 2012 · Assuming that HIF2α binds with ARNT through its PAS domains, our data may explain why ARNT is not recruited with HIF2α to the FVII promoter under hypoxia. Notably, the mechanism described in this study is similar to that of constitutive FVII expression under normoxia in breast cancer cells ( 10 ), where the same Sp1-binding …
