Ethanol decreases mTOR pathway signaling in lymphocytes. Representative Western blot analysis of (A) Raji and SUDHL-4, (B) B cells and PBLs, and (C) MCF-7, BT-474, and BT-20 cells after 10 days of ethanol treatment (0-20 mM). A total of 50 μg total protein lysates was loaded, and the abundance of pmTOR, mTOR, pRPS6, RPS6, p-p70S6K, p70S6K, and β-actin was assessed.
