Binase Do Not Change Level of Intracellular RNA in Breast Cancer Cells

Abstract

© 2017, Springer Science+Business Media, LLC. We analyzed changes of intracellular RNA level in breast cancer cells using BT-20, BT-474, and MCF-7 cell lines. It is the continuation of our former studying the effect of bacterial ribonucleases on physiological and biochemical parameters of breast cancer cells. For the first time, we tested ability of Bacillus pumilus RNase (binase) to effect the level of intracellular RNA in these cells. Differences in total RNA level under of the binase action on the cells of triple negative, triple positive, and double positive breast cancer during 48 h of treatment were not detected. The sensitivity of cells to binase was not associated with a reduction of the intracellular RNA level.
