Together with the results shown in Supplementary Figure 10, which indicate that neither forced expression nor depletion of p62 impaired the growth rate of breast cancer cells in a short time frame, as indicated by proliferative assays of up to 4th–6th day, suggesting that p62 is not capable of influencing the short-term proliferative ability of breast cancer cells. Here, SQSTM1 is linked to breast cancer.
