Web21 de abr. de 2011 · Further study of HIF TADs reveals that not all are essential for HIF function. In particular, deletion of the putative ARNT C-terminal TAD has a minimal effect on transactivation of endogenous targets (5–7), whereas deletion of the two HIF-α TADs (N-TAD and C-TAD) eliminates hypoxia-induced transactivation ().Consequently, study of … Web15 de mar. de 2024 · It is feasible that a high ARNT isoform 1:3 ratio, which corresponds to a general reduction in AhR activity, might instead promote ARNT-HIF-α activity . Moreover, HIF-2α (encoded by EPAS1 ) is an essential mediator of Treg suppressor cell function, and deletion of EPAS1 in Treg cells drives reprogramming toward interleukin-17–secreting …
