Musashi-1 is an RNA binding protein involved in Notch-1 signaling pathway: Götte et al. showed an increased expression of Musashi-1 protein in endometriosis and endometrial carcinoma and expression of Small interfering-RNA (siRNA), able to inhibit Musashi- 1, in EC cells, reduces cell proliferation inducing also apoptosis [89]. Here, MSI1 is linked to endometriosis.
