The growth of Swiss 3T3 cells can be inhibited by the addition of a plasma membrane enriched fraction from 3T3 cells [Whittenberger, B & Glaser, L. (1977) Proc. Natl. Acad. Sci. USA 74, 2251--2255]. We report conditions for the extraction of the inhibitory components from the membranes with octylglucoside. The solubilized components reversibly inhibit the rate of cell division of 3T3 but not of simian virus 40-transformed 3T3 cells. The inhibitory activity is heat labile and nondialyzable. The inhibition observed with the soluble extract can be reversed by mitogenic factors present in serum.
添加来自3T3细胞的富含质膜的组分能够抑制瑞士3T3细胞的生长[惠滕伯格,B和格拉泽,L.(1977年)《美国国家科学院院刊》74,2251 - 2255]。我们报告了用辛基葡糖苷从膜中提取抑制成分的条件。溶解的成分可逆地抑制3T3细胞的细胞分裂速率,但不抑制猿猴病毒40转化的3T3细胞的细胞分裂速率。抑制活性对热不稳定且不可透析。血清中存在的促有丝分裂因子可逆转可溶性提取物所观察到的抑制作用。
