Neuraminidase 1 regulates proliferation, apoptosis and the expression of Cadherins in mammary carcinoma cells.

The link between Neuraminidase 1 (Neu1) and cancer development has been highlighted in numerous studies. In an effort to understand the role of Neu1 in mammary carcinoma cells, we evaluated the effect of Neu1 on controlling cell proliferation and apoptosis, as well as regulating the expression of cadherins. By blocking the activity of Neu1 with oseltamivir phosphate or using siRNA to silence the Neu1 protein, we observed suppression of cell growth in MCF-7 and MDA-MB-231 cells.
