[Polymorphism of genes of the renin-angiotensin system ACE, AT1R, and AT2R in patients with pulmonary tuberculosis].

The goal of this work was to verify the hypothesis about the possible role of some genes of the renin-angiotensin system in the innate immunity to tuberculosis. The insertion/deletion polymorphism (I/D) of the gene of the angiotensin-converting enzyme (ACE) is known to have an effect on the concentration of the angiotensin II in human body and also an indirect effect on various branches of metabolism. On the one hand, people with homozygote deletion of the ACE gene (DD genotype) are vulnerable to adiposity, arterial hypertension, hypercholesterolemia, and a number of other pathological conditions.

[Dynamics of the biosynthesis of components of the protein synthesizing apparatus of the rat liver at the stage of restoration of translation, inhibited by cycloheximide].

The biosynthesis of proteins, ribosomal RNA and other components of the rat liver protein-synthesizing system during the reparation and subsequent activation of translation inhibited by a sublethal dose cycloheximide (CHI, 3 mg/kg) was studied. It was found that the incorporation of labeled precursors into proteins and ribosomal rRNA isolated from free and membrane-bound polysomes is repaired already 3 hours after CHI injection. 6-9 hours thereafter, the level of component labeling reaches control values, whereas the total protein biosynthesis is retarded.

[Characteristics of [3H]cycloheximide distribution, protein and DNA biosynthesis in rat organs after sublethal blocking of translation].

The kinetics of accumulation and release of [3H]cycloheximide (CHI) as well as protein and DNA biosyntheses in some organs of the rats injected with sublethal doses of CHI were studied. It was shown that in the majority of organs under study (especially in the liver, kidneys and adrenals) the inhibition is completed within 12 hours after CHI injection followed by the resumption of protein and DNA syntheses. In the thymus and pancreas the levels of these biosyntheses remain below control values up to the 72nd hour.

[Activation of nuclear polypeptide synthesis in rat liver cells after inhibition of template protein synthesis. The role of nuclear polypeptide synthesis in the changes of the chromatin structure].

The correlation between the rates of nuclear polypeptide synthesis (NPS) and matrix protein synthesis in rat liver cells was investigated. It was shown that NPS is activated under conditions of protein synthesis inhibition in the cytoplasm. Model experiments revealed that the NPS and ADP ribosylation systems compete for chromatin structure: ADP ribosylation induces condensation, while NPS--decondensation of chromatin.
