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.
