The effect of hsa_circ_0013401 knockdown on apoptosis and autophagy was clear since the authors demonstrated an increase in the protein levels of Bax, cleaved caspase-3, LC3B-II/I ratio, and Beclin 1, and hence this molecule may be affecting the tumour growth, proliferation and migration steps (steps 1–2 and 4) [34]. Here, BECN1 is linked to neoplasm.
