From: The growth response to androgen receptor signaling in ERα-negative human breast cells is dependent on p21 and mediated by MAPK activation

Figure 8

p21-/- cells do not stimulate mitogen-activated protein kinase (MAPK) signaling upon androgen receptor (AR) ligand binding. Control cells (MCF-10A p21-/- and p21-/- plus vector) and AR-expressing cells (p21-/- AR-1 and p21-/- AR-4) were cultured under normal propagation conditions in the presence or absence of 20 ng/ml epidermal growth factor (EGF), and treated with either vehicle or 1 nmol/l R1881 for 48 hours. Western blotting was performed on whole-cell lysates. Blots were probed for phosphorylated extracellular signal-regulated kinase (ERK) (Thr-202/Tyr-204) and total ERK. GAPDH antibody was used as a loading control.
