The rate of DNA synthesis and the activity of DNA polymerases and thymidine kinase were measured during the endocrine-regulated cellular growth and differentiation of mouse mammary gland. Using specific assays, the activity of the DNA polymerases, alpha, beta and gamma, was determined in tissue extracts of mammary glands of mice at various stages of(More)
The role of extracellular Ca2+ in the control of DNA synthesis in mouse mammary tissue was studied using mammary gland explants maintained under chemically defined conditions in vitro. Chelation of calcium with ethyleneglycol-bis-(beta-aminoethyl ether) or omission of Ca2+ from the incubation media substantially reduced both basal and insulin-stimulated(More)
