Therefore, ex-miRs have the potential for early breast cancer diagnosis.[55] Wang et al conducted a study on 55 breast cancer patients and 55 healthy controls and discovered that ex-miR-1910-3p promoted the proliferation and migration of breast cancer cells both in vitro and in vivo by downregulating myotubule-associated protein 3 and activating the NF-κB and wnt/β-catenin signaling pathways. The gene discussed is NFKB1; the disease is breast cancer.
