Interestingly, higher mRNA expression of PEX 11B/11G/11A/12/19 (PEX11B: HR = 0.75, 95% CI: 0.62-0.91, P = 0.03; PEX11G: HR = 0.71, 95% CI:0.54-0.93, p = 0.012; PEX11A: HR = 0.81, 95% CI: 0.67–0.98, P = 0.029; PEX12: HR = 0.69, 95% CI:0.57-0.83, p = 9.7e-05; PEX19: HR = 0.75, 95% CI:0.62-0.91, p = 0.003;) was significantly associated with longer overall survival (OS) of BC patients (Fig6). This evidence concerns the gene PEX12 and breast cancer.
