A Model for the Regulation of delta-Aminolaevulinate Synthetase Induction in Rat Liver

Padmanaban, Govindarajan; Rao, M R S; Malathi, Krishnamachari (The Biochemical Society, 1973-08)

A reciprocal relationship exists between the cytochrome P-450 content and δ-aminolaevulinate synthetase activity in adult rats. In young rats the basal δ-aminolaevulinate synthetase activity is higher and the cytochrome ...
On the Sequence of Reactions Leading to Cytochrome P-450 Synthesis-Effect of Drugs

Rajamanickam, Chellam; Rao, M R S; Padmanaban, Govindarajan (The American Society for Biochemistry and Molecular Biology Inc, 1975)

The effect of phenobarbital on the rates of the synthesis of the protein and heme moieties of cytochrome P-450 has been studied. For this purpose, cytochrome P-450 has been partially purified as its P-420 derivative and ...
Effect of allylisopropylacetamide on Nuclear Ribonucleic Acid synthesis in rat liver

Sardana, M K; Rao, M R S; Padmanaban, G (Portland Press, 1975)

The porphyrogenic drug allylisopropylacetamide, a potent inducer of delta-aminolaevulinate synthetase, specifically increases nucleoplasmic RNA synthesis in rat liver. The drug-mediated increase in nucleoplasmic RNA synthesis ...
Antigenically active nonhistone chromatin proteins in cancer cells

Busch, Harris; Yeoman, Lynn C; Busch, Rose K; Jordan, John J; Rao, M R S; Taylor, Charles W; Wu, Benjamin C (American Association for Cancer Research, 1976-09)

Two-dimensional polyacrylamide gel electrophoresis shows that in nuclei of Novikoff hepatoma ascites cells there are approximately 75 proteins in the chromatin fraction soluble in 3 m NaCl:7 m urea. Dialysis of this fraction ...
Effects of U1 Nuclear RNA on Translation of Messenger RNA

Rao, M R S; Blackstone, Marilyn; Busch, Harris (American Chemical Society, 1977-06)

U 1 nuclear RNA has the 5’-terminal sequence m32,2,7Gpp(p)AmUmACUUACCUGGCAGGGAGAUACCAGG- [Reddy, R., et al. (1974), J. Biol. Chem. 249, 6486; Ro-Choi, T. S., et al. (l974), Fed. Proc., Fed. Am. Soc. Exp. Biol. 33, ...
Isolation and Characterization of Binding Proteins for Retinol from the Cytosol, Nucleosol and Chromatin of the Oviduct Magnum of Laying Hens

Rao, M R S; Prasad, V R; Padmanaban, Govindarajan; Ganguly, Jagannath (The Biochemical Society, 1979)

Protein fractions that bind retinol were isolated from the cytosol, nucleosol and chromatin of the oviduct magnum of laying hens. The proteins isolated from the three sources showed similar elution profiles on chromatography ...
A Comparative Study of the Early Effects of Phenobarbital and 3-Methylcholanthrene on the Synthesis and Transport of Ribonucleic Acid in Rat Liver

Kumar, Ashwani; Rao, M R S; Padmanaban, Govindarajan (The Biochemical Society, 1980)

At 2-3 h after phenobaribtal administration, the drug has no effect on nucleoplasmic RNA synthesis and decreases nucleolar RNA synthesis. However, at this time there is an increase in the labelling of cytoplasmic ...
Localization of testis-variant histones in rat testis chromatin

Rao, M R S; Rao, Basuthkar Jagadeeshwar; Ganguly, Jagannath (The Biochemical Society, 1982)

Nucleosome core particles and oligonucleosomes were isolated by digesting rat testis nuclei with micrococcal nuclease to 20% acid-solubility, followed by fractionation of the digest on a Bio-Gel A-5m column. The core ...
Structural organization of the meiotic prophase chromatin in rat testes

Rao, Basuthkar Jagadeeswar; Brahmachari, Samir K; Rao, M R S (American Society for Biochemistry and Molecular Biology, 1983)

Pachytene nuclei were isolated from rat testes by the unit gravity sedimentation technique and contained histone variants H1a, H1t, TH2A, TH2B, and X2 in addition to the somatic histones H1bde, H1c, H2A, H2B, H3, and H4. ...
A quantitative analysis of germ cells and the histone variants in the testes of vitamin A-deficient rats and during subsequent repletion with vitamin A

Unni, Emmanual; Rao, M R S (Indian Academy of Sciences, 1985-06)
