To further validate their possible contribution to OC mesenchymal subtype, we found that both CXCR7 and CXCL11 strongly correlate with genes associated with ECM and OC invasion, such as PRRX1, TMEM45A, and CTSK, when analyzed in the mesenchymal counterpart of ovarian tumors (Fig. S7). The gene discussed is TMEM45A; the disease is ovarian neoplasm.
