Comparative enzymatic degradation of H1 subfractions from Syrian hamster tissues.

Distribution of the H1 histone subfractions in Syrian hamster chromatin fractions.

Chromatin from two Syrian hamster tissues: the Kirkman-Robbins hepatoma and the liver, has been separated into soluble (S) and insoluble (P) fractions. Both fractions contain the complete set of five main histones but differ in respect of H1 subfractions. The hepatoma chromatin is known to contain an unusual H1 subfraction, H1 slow [12, 13], probably identical with a similar subfraction present...

Distribution of the H I Histone Subfractions in Syrian Hamster Chromatin Fractions

Chromatin from two Syrian hamster tissues: the Kirkman-Robbins hepatoma and the liver, has been separated into soluble (S) and insoluble (P) fractions. Both fractions contain the complete set of five main histones but differ in respect of HI subfractions. The hepatoma chromatin is known to contain an unusual HI subfraction, HI slow [12, 13], probably identical with a similar subfration present ...

A low-electrophoretic-mobility H1 histone subfraction from Kirkman-Robbins hamster hepatoma.

A protein showing lower electrophoretic mobility in acidic urea polyacrylamide gels than did the usual histone H1 subfractions has been detected among the H1 histones extracted from chromatin of a transplantable hamster hepatoma, originally induced by Kirkman and Robbins. It was proved to be a true H1 histone subfraction. It differs from the remaining ones by the total chain length, amino acid ...

Insulin deficiency and reduced expression of lipogenic enzymes in cardiomyopathic hamster.

Evidence is given that the heart of the cardiomyopathic UM-X7.1 hamster has a lipid composition different from that of the same tissue isolated from animals of the Syrian hamster parent strain. Also, noncardiac tissues from cardiomyopathic and healthy hamsters exhibit significant compositional differences. On the basis of these preliminary observations, a comparative study of the hepatic biosyn...
