Studies on chromatin. II. Effects of carcinogens and hormones on rat liver chromatin.
Nuclei were isolated from rat liver during the prolonged feeding of the 2 carcinogens, N-hydroxy^-acetylaminofluorene and 3'-methyl-4-dimethylaminoazobenzene, and during the pro longed feeding of the noncarcinogen, 2-methyl-4-dimethylaminoazobenzene. Nuclei were also isolated from rat liver tumors induced by the above carcinogens. Chromatin was isolated from these nuclei and analyzed for RNA, t...
متن کاملAllele-Specific Chromatin Immunoprecipitation Studies Show Genetic Influence on Chromatin State in Human Genome
Several recent studies have shown a genetic influence on gene expression variation, including variation between the two chromosomes within an individual and variation between individuals at the population level. We hypothesized that genetic inheritance may also affect variation in chromatin states. To test this hypothesis, we analyzed chromatin states in 12 lymphoblastoid cells derived from two...
متن کاملBiophysical studies of cholesterol effects on chromatin[S]
Changes in chromatin structure regulate gene expression and genome maintenance. Molecules that bind to the nucleosome, the complex of DNA and histone proteins, are key modulators of chromatin structure. Previous work indicated that cholesterol, a ubiquitous cellular lipid, may bind to chromatin in vivo, suggesting a potential function for lipids in modulating chromatin architecture. However, th...

متن کاملStudies on the chromatin of barley leaves during senescence.
1. The activity of soluble ribonuclease and deoxyribonuclease first declined during senescence, but later increased during advanced stages of senescence. 2. Young leaves had very low ribonuclease or deoxyribonuclease activity associated with the chromatin, but the activity of these enzymes increased progressively during senescence until the leaves died. 3. No significant changes in the composit...
