Fig. 7From: Deciphering the impact of circRNA-mediated autophagy on tumor therapeutic resistance: a novel perspectiveDysregulated circRNAs are involved in autophagy-mediated resistance to chemotherapy and radiotherapy in cancer. The majority of circRNAs act as miRNA sponges, which sequester miRNAs and prevent them from regulating their downstream mRNA targets, thereby affecting the initiation of autophagy. Only a few circRNAs directly interact with proteins to modulate autophagyBack to article page
