SOX10 and breast carcinoma: Consistent with our TCGA analysis (also see [23, 37]) and murine data, we observed that 43% of TNBC cores were Sox10hi and that all Sox10hi nuclei in those cores also showed a pSox9 S181hi signal (Fig. 3d), suggesting that the activation of Sox9 and Sox10 induction is also observed in human breast cancer samples.
