Our results with AML 12 cells indicate that mTORC1 activation upon palmitate treatment downregulated the expression of autophagy genes Atg7 and Beclin1 and increased the accumulation of autophagic cargo SQSTM1/p62, thereby suggesting the autophagic blockade in lipotoxic AML 12 cells. The gene discussed is BECN1; the disease is acute myeloid leukemia.
