  • Title: [Genetic transformation of somatic cells. V. Inheritability of the rate of loss of the trait and the stabilization of the transformant phenotype].
    Author: Glebov OK, Abramian DS, Smirnova TM.
    Journal: Tsitologiia; 1985 Jun; 27(6):670-7. PubMed ID: 2992136.
    Abstract:
    Subclones were isolated both on selective and nonselective medium from the Chinese hamster cells transformed by thymidine kinase gene (TK-gene) of Herpes simplex virus (HSV-1) and varying in the rate of the loss of transformant phenotype. The study of the stability of thymidine kinase-positive (TK+) phenotype in cell populations the subclones shows that the nonstability and the rate of the loss of transformant phenotype are the characters that are inherited in the cell generations. Durable cultivation on a HAT-selective medium may lead to a complete or partial (expressed as a reduced rate of the loss of the character) stabilization of TK+-phenotype of the cells of transformant clones. The rate of stabilization of TK+-phenotype may differ depending on the structure of transforming DNA introduced into cells of transformant clones.
