Figure 4. Regulation of endogenous αB-crystallin protein levels by Ets1 in basal-like breast cancer cells.

Figure 4

(A) MDA-MB-231 pools stably expressing pBABE vector or pBABE-Ets1 were created by retroviral transduction. Ets1, αB-crystallin and actin levels were determined by immunoblotting. (B) MDA-MB-231 cells were transiently transfected with 25 µM Ets1 siRNA or a control (C) lamin A/C siRNA. Ets1, αB-crystallin and actin levels were determined by immunoblotting 72 h later.
