However, it is unclear whether the activation of autophagy in breast cancer DTP cells is related to their overexpression of the transcriptional regulatory factor CDCA7.<h4>Methods</h4>We analyzed CDCA7 expression using public datasets and clinical samples and established breast cancer cell lines with CDCA7 overexpression and knockdown to assess the role of CDCA7 in breast cancer. Here, CDCA7 is linked to breast cancer.
