[Semi-centennial history of the nuclear matrix at the turn of the 21st century].

In 1974, Berezney and Coffey described what they called the nuclear matrix (NM), thus ignoring our priority, since we had isolated and characterized virtually the same skeletal structure 25 years before this discovery. The presence of NM in the live cell was doubted, because of unsuccessful attempts to recognize it in vivo. NM comprises the lamina, extracted nucleoli and an intranuclear fibrogranular network.

[Proteins of the nuclear matrix and their phosphorylation in normal and tumor cells].

The protein composition of the nuclear matrix of normal and tumor cells is discussed. A characteristic feature of the latter is the predominance of high molecular weight polypeptides containing mainly glyco- and phosphoproteins. Only few of them are identified.

[Effect of colostrum polypeptide on structure and lipid peroxidation in liver nuclei of rats late after gamma-irradiation].

Rats were irradiated by 8Gr in a doze power of 2.33 R per second. A portion of animals were injected subcutaneously with a cow colostrum polypeptide (CP) in a doze of 1 mg per g of body weight before the irradiation and daily after the irradiation during 4 days.
