Does y-box protein 1 stimulate mesangial cell proliferation via activation of ERK1/2?
YB-1 has an apparent stimulatory effect on c-Raf, MEK1/2, ERK1/2 and cell-cycle progression in MCs, after which activated ERK1/2 goes on to upregulate YB-1 expression and augment the proliferative effect of YB-1.
Together, these findings establish WAVE3 as a novel marker for increased risk of breast-cancer-specific mortality and for the metastatic potential of the TNBCs, and also identify WAVE3 as an attractive therapeutic target for the treatment of metastatic BC.
