Effect of miRNA34a inhibition on autophagy. Schematic representation of promoter methylation, which represents the most common cause of miRNA34a decreased expression in tumors and of the principal effects of miRNA34a low expression in the sustainment of cancer proliferation. Particularly, we highlighted the main pathway involved in the regulation of autophagy by miRNA-34a.
