To study further the factors providing for cellular quiescence, we used okadaic acid (OA) at concentrations (0.1, 1, 10 or 100 nM) inhibiting type 1 and/or type 2A protein phosphatases in mammalian cell cultures. Brief (2 h) exposure of resting (0.2%

There is evidence that resting cells are able to produce molecules with antiproliferative activity, some of which behave as short-lived repressor proteins. We suggest that transient inhibition of protein synthesis in resting cells would lead to a dec

Control over cell growth in eukaryotes is predominantly achieved by regular transition of cells from proliferation to rest and vice versa as a result of a co-ordinated inter-relationship between intracellular growth inhibitors and extracellular growt

Incubation of resting (serum-deprived) NIH 3T3 mouse fibroblasts for 12 hours with PDGF1) stimulates the onset of DNA synthesis. A brief exposure (45 minutes) of resting cells to inhibitors of protein synthesis (cycloheximide or puromycin) exerts sim

The effects of various cytotoxic chemicals, as measured by viable cell counts, colony-forming ability and proliferative capacity, have been studied using Chinese hamster cells in exponential and plateau (stationary) phases of growth. The proliferatin

A comparative study was performed on the duration of mitosis and interkinesis in the corneal epithelium, uterine epithelium, ear epidermis and bone marrow of albino mice. The colchicine technique and total irradiation were employed. Shortcomings and

In comparison with the usual mitotic activity during estrus, the mitotic activity of the epithelium uterine mucous membrane rises on the 2nd and 3rd days, decreases considerably on the 5th and ceases entirely on the 8th day of pregnancy. These change

Estrone administration stimulates mitosis of the uterine epithelium in castrated mice, inhibiting it, however, in repated injections. Discontinuance of estrone administration at the time of intensive cell multiplication leads to reduction of mitotic

Only individual mitoses are observed in the epithelium of the uterine mucous membrane of mice on the 20th day after ovariectomy. Following 2 folliculin injections the number of cell divisions is considerably increased; after 6 injections—the number

Spayed female mice received a daily injection of 2.3 γg of esterone. Intraperitoneal injection of 13 γCH3 thymidine was given to mice after a various number of estrone injections. The mice were killed 4 h later. The mitotic index of the uterine epi
