BECN1 and neoplasm: Recently, studies found that the expression of autophagy-related proteins (ATGs) at CAFs or cancer cells, such as microtubule-associated protein light chain 3 (MAP1LC3/LC3), Beclin-1 (BECN1) and sequestosome 1 (SQSTM1 /p62) et al., might be promising indicators of for tumor recurrence and prognosis [6, 7].
