EGR1 and hereditary clear cell renal cell carcinoma: At concentrations of 25–100 μM, Cyanidin-3-O-glucoside (C3G) inhibits the proliferation of renal cell carcinoma cells and tumorigenesis by arresting the cell cycle, inducing apoptosis and autophagy by regulating the expression of early growth response protein 1 (EGR1), selenoprotein W1 (SEPW1), p62 or sequestosome 1, and autophagy related gene 4 (ATG4) (93).
