G6PD and breast cancer: To investigate a clinical relevance of the lactic acid-responsive G6PDY249/322 Tyr phosphorylation and G6PD-SRC-GSTP1 complex, and to establish their potential correlation with breast cancer types, we obtained 13 human breast cancer (T) samples along with adjacent tissues (N) characterized to be normal, and made lysate for detailed IP analyses (Fig. S6A).
