Alteration of transcription factor protein levels by treatments. Immunoblots of nuclear extract were performed after treating cultures with (A, B) 2 μM arsenite (As), or (B) 10 μM vanadate (Va), 10 μM cadmium (Cd), 3 μM chromate (Cr) or 10 μM hemin (He) as indicated. Cultures were harvested for analysis 2 days before confluence or 3, 7 or 11 days after confluence as indicated (−2, 3, 7 11) (A) or 7 days after confluence (B). β-Actin was used as a loading control. The numbers below the lanes show amounts of protein (detected by scanning the blots) which are normalized to β-actin and expressed relative to the untreated value (NT) at day −2 (A) or 11 (B).
