A study on Notch signaling in human breast cancer.

Abstract:

:Breast cancer is one of the leading causes of cancer death in women. The Notch family of proteins plays crucial roles in determining cell fates such as proliferation, differentiation and apoptosis. A role for Notch signaling in human breast cancer has been suggested by the development of adenocarcinomas in the murine mammary gland. However, it is not clear currently whether Notch signaling is frequently expressed and activated in breast cancers. Here we show that Notch signaling is overexpressed and highly activated in breast cancers. More significantly, the attenuation of Notch signaling by gamma-secretase inhibitor can inhibit the proliferation of breast cancer cells by both causing cell cycle arrest and apoptosis. Thus, targeting Notch signaling may be of therapeutic value in breast cancers.

  • MicroRNA-363-3p/p21(Cip1/Waf1) axis is regulated by HIF-2α in mediating stemness of melanoma cells.

    abstract::Melanoma is a malignant tumor. The acquisition of stemness of melanoma cells aggravates the malignant transformation, which can be regulated by microRNAs (miRNAs, miR). MiR-363-3p is a key tumor-related miRNA, but its role in stemness and melanoma cells is still unknown. Presently, miR-363-3p, induced by hypoxia induc...
