Kanlikilicer et al. showed that exosomes from paclitaxel-resistant ovarian cancer (OC) cells could transfer miR-1246 to M2-type macrophages, allowing miR-1246 to bind to the 3′UTR of caveolin-1 (Cav1) and function through platelet-derived growth factor receptor (PDGFR) tyrosine signaling to inhibit cell proliferation [63]. The gene discussed is CAV1; the disease is ovarian cancer.
