The vitamin A effects on cell proliferation, differentiation and functioning might be due to its influence on genome expression at the level of regulation of the transcription of certain genes, posttranscriptional modification of mRNA levels, or chan

Retinyl phosphate (RP) has been synthesized from retinol (R), using phosphodimorpholine chloride (PDMC) or POCl3. A method for isolating and purifying RP from the reaction mixture has been developed. The RP yield varies from 3 to 6% depending on the

Retinol deficiency in rats was shown to cause atypical changes of DNP-complex in spermatogenic cells and a decrease in their fertility. The final stages of spermiogenesis were found to be the most sensitive: ca. 25% of testicular sperms were characte

The clastogenic and mutagenic activities of a new antifertility and antitumor agent gossypol were studied in the mouse male germ cells. Results of the present work indicate that at the doses 125 and 250 mg/kg the drug does not significantly increase

It has been shown that in rats with alimentary hypovitaminosis A, with a sufficiently pronounced decrease in the content of free retinol in blood serum (below 140 ng/ml) and in the liver tissue (below 360 ng/g), there is a complete regression of Plis

Enzymic hydrolysis of retinyl phosphate in subcellular fractions of the rat liver has been investigated. A quantitative method of measuring activity of retinyl phosphatase has been developed. The method is based on the isolation of labeled retinol, t
