ATG5 and melanoma: The analyses of autophagy genes by means of real-time PCR showed that the treatment with complex 1 induced the downregulation of ATG5 (Fig. 7J) and ATG7 (Fig. 7K) genes in melanoma B16F10 in both concentrations tested and in sarcoma 180 induced the upregulation of ATG5 (Fig. 7L) and ATG7 (Fig. 7M) in the lower concentration of complex 1.
