title: [Comparative study of the influence of renal endogenic factors on the proliferation activity of epithelial cells].
abstract: The proliferation activity of monolayer culture of Madin Darby Canine Kidney (MDSK) cells is suppressed by a thermostable protein factor of renal tissue of white rats and of humans. Under the influence of renal factors (RF), a decrease in cell number, and suppression of DNA synthesis and mitotic activity in MDCK cells occur. The inhibition of proliferative activity of cultured cells under the influence of RF was substantiated also by MTT assay. It was established that the inhibitory influence of RF is stipulated by suppression of RNA synthesis. It follows that RF may inhibit division of MDCK cells via suppression of gene expression in G1-phase. Similar factors were obtained from renal cells of different systematic groups of organisms (snail, frog, fish, pigeon, guinea pig, swine).
