[[Length polymorphism of minisatellite repeat B2-VNTR of the bradykinin B2 receptor gene in healthy Russians and in patients with coronary heart disease].

Bradykinin B2 receptor is involved in many processes, including the regulation of blood pressure and smooth muscle contraction, vasodilation, inflammation, edema, cell proliferation, pain. It is suggested that this receptor may be one of the factors that have cardioprotective and infarct-limiting effects. It is assumed that certain genetic variants in both coding and non-coding regions ofBDKRB2 gene may influence its expression.

[Multicenter retrospective analysis of the patients with sarcoidosis with a 10 year interval in observations].

Comparison of the state of 83 patients with histologically confirmed sarcoidosis observed with a 10 year interval revealed remission in 47% of the cases. The main factors having negative effect on prognosis of the disease included extrapulmonary symptoms, the use ofcorticosteroids (at all stages, especially at stage I and in Lofgren syndrome) and antituberculosis drugs, positive TB test. Risk factors of relapses were stage II sarcoidosis, the use of systemic corticosteroids in patients with Lofgren syndrome and antituberculosis drugs, initially low FEV1/FVLC ratio and the number of lymphocytes in peripheral blood.

[Transthyretin gene V30M, H90N, and del9 mutations in cardiomyopathy patients from St. Petersburg].

A search of transthyretin (TTP) gene mutations was conducted in patients with cardiomyopathies from St. Petersburg. Mutations H90N, V30M, G47A, and deletion (del9) of nucleotides GACTTCTCC in position 6776 from the start codon of the TTP gene (in position 98782 according to reference sequence AC079096 (NCBI) was found.

[Human intra-intronic minisatellite UPS29 associated with neurological diseases regulates reporter gene EGFP expression depending on cell type].

Earlier, it was established that polymorphism of minisatellite UPS29 located in one of introns of human gene CENTB5 (ACAP3) was associated with Parkinson's disease and epilepsy. The main aim of this work was to elucidate if that minisatellite could regulate reporter gene activity, and if such activity was tissue (cell)-specific. To this end there was used transient transfection of HeLa cells, mouse embryonal carcinoma line F9, and rat astrocytes cultures with plasmides which contained reporter gene EGFP under eukaryotic promoter ROSA26 and different allelles of minisatellite UPS29.

[Comparison of crude lysate pellets of isogenic strains of yeast with different prion composition: identification of a set of prion-associated proteins].

A new approach: comparative analysis of proteins of the pellets of crude cell lysates of isogenic strains of Saccharomyces cerevisiae differing by their prion composition permitted to identify a large group of prion-associated proteins in yeast cells. 2D-electrophoresis followed by MALDI-analysis of a recipient [psi-] strain and of [PSI+] cytoductant led to identification of 35 proteins whose aggregation state responded to a shift of prion(s) content. Approximately half of these proteins belonged to functional groups of chaperones and enzyme involved in glucose metabolism.
