Activation of c-Jun N-terminal kinase (JNK) signaling pathway in MCF-7 and MCF-7:2A cells in response to buthionine sulfoximine (BSO) and 17β-estradiol (E2) treatment. a MCF-7 and MCF-7:2A cells were treated with ethanol vehicle (control), 1 nM E2, 100 μM BSO, or BSO plus E2 for 48 h and protein levels of phosphorylated JNK, JNK, phosphorylated c-Jun, and c-Jun were analyzed by western blotting. β-Actin was used as a loading control. Data shown is representative of 3 separate experiments yielding similar results
