Circ-DNMT1 was reported to interact with both p53 and AUF1 (AU-rich element-binding factor 1) and promote the nuclear translocation of both proteins, and nuclear translocation of p53 induced autophagy, while nuclear translocation of AUF1 increased the stability of DNMT1 mRNA, leading to an increased translation of DNMT1, which ultimately increases the proliferation of breast cancer cells by stimulating cellular autophagy [33]. Here, TP53 is linked to breast cancer.
