In order to explore whether the autophagy induced by chronic exposure with respect to butyrate was related to AMPK/ACC and Akt/mTOR signaling pathways, immunoblot analysis was performed in PT, AT1.6, AT6.4, and BR colon cancer cells of HCT116, HT29, and SW480 (Figure 5). The gene discussed is AKT1; the disease is malignant colon neoplasm.
