In ovarian cancer, the association of PBX1 and proliferation was observed to be NOTCH3-dependent (Park et al., 2008), and PBX1-mediated chemoresistance to be related to PBX1 binding to STAT3 promoter, positively regulating its transcription (Jung et al., 2016). The gene discussed is PBX1; the disease is ovarian carcinoma.
