[The structure and specific features of the cDNA expression of the human gene MRPL37].

A 147-bp cDNA fragment was isolated from human lymphocytes activated with concanavalin A using the method of direct selection. A complete copy of the selected gene having total homology with the mitochondrial ribosomal gene MRPL37 was obtained by the RACE (rapid amplification of cDNA ends) technique. The MRPL37 gene was localized on human chromosome 1 using a DNA panel composed of somatic cellular human-hamster hybrids.

The human RIL gene: mapping to human chromosome 5q31.1, genomic organization and alternative transcripts.

The ril gene encoding a LIM domain protein of an unknown function was previously identified by differential expression cloning as a candidate tumor suppressor gene in rat fibroblasts (Kiess, M., Scharm, B., Aguzzi, A.

[Effect of the topography of the signal peptidase site on the effectiveness of secretion of recombinant human granulocyte-macrophage colony-stimulating factor into Escherichia coli periplasm].

Synthesis of an artificial gene encoding the signal peptide of the Yersinia pestis capsule antigen (Caf1) was accomplished. A set of plasmids coding for hybrid proteins in which a modified sequence of the Caf1 signal peptide is connected to the amino acid sequence of the mature granulocyte-macrophage colony stimulating factor (GM-CSF) were constructed. Topography of the cleavage site of signal proteases was studied.

[Cytotoxic activity of normal killers and the lymphocytic proliferative response to specific viral antigens in influenza in mice].

Inoculation of CBA mice with pathogenic influenza A/PR8/34 (H1N1) virus and non-pathogenic A/Krasnodar/101/59 (H2N2) virus demonstrated that the pathogenic strain enhanced the synthesis of serum interferon and activated the function of normal killers, but had a relatively low capacity of causing in vitro proliferative response of spleen lymphocytes of intact and in vivo primed animals. In contrast, the nonpathogenic virus had less marked interferon-inducing capacity and that of activating normal killers, but induced a very high proliferative response of lymphocytes in culture.
