SQSTM1 and lip and oral cavity carcinoma: To investigate the effect of resveratrol on the expression of autophagy-related markers (p62, Beclin1, and LC3) in oral cancer cells, proteins extracted from Ca9-22 cell cultures were treated with various non-cytotoxic concentrations (2–100 μM) of resveratrol and for various time periods (0, 4, 8, 12, 24, 48, and 72 h) that were quantified using immunoblot analysis.
