Comparison of the AIB1 and ERα expression profile in normal versus long-term estrogen deprived breast cancer cells. (A,B) Western blotting analysis of AIB1 and ERα protein expression in LTED and UMB-1Ca cells treated with either vehicle (0.1% ethanol) or various doses of estradiol for 5 days. Results of immunoblotting with anti-AIB1 and anti-ERα are shown in duplicate. (Lanes 1–2 represent 10−12 M; lanes 3–4 represent 10−11 M; lanes 5–6 represent 10−10 M; lanes 7–8 represent 10−9 M; lanes 9–10 represent 10−8 M; lanes 11–12 represent 10−7 M; lanes 13–14 represent 10−6 M; lanes 15–16 represent vehicle control.) (C,D) Blots were striped and reprobed for β-actin and corrected for the internal loading control. Bands were quantitated by densitometry using Molecular Dynamics Software (ImageQuant) and values were corrected for by normalizing to the β-actin internal control and represented as a percentage of the vehicle control±SEM (n=3).
