[Activation of the RIG-I gene, coding for DEXH/D-protein in infection of RH cells by tick-borne encephalitis virus].

It was demonstrated by subtractive hybridization that the infection of a human embryonic kidney cell line with tick-borne encephalitis virus causes an approximately tenfold transcription activation of the RIG-1 gene, which encodes a protein of the DExH/D-box-containing RNA helicase family. A possible involvement of the protein in antiviral cell systems is discussed. The English version of the paper: Russian Journal of Bioorganic Chemistry, 2004, vol.

[Late activation of interferon-induced genes IFI-54k and IFI-56k in human RH cells infected with tick-borne encephalitis virus].

The genes that were induced and suppressed in human embryonic kidney cell line RH upon the infection with tick-borne encephalitis virus were studied by the method of subtractive hybridization. The expression of interferon-induced genes IFI-54K and IFI-56K in the infected cells was found to increase 50-100-fold.

[Isolation and characteristics of an ordered library of transcribed sequences of human chromosome 19 from hybrid human-hamster cells].

A new technique based on Alu-PCR amplification of hn-RNA is described for the extraction of human-specific transcribed sequences from a hybrid cell line. Arrayed library of hn-cDNA was constructed and characterized by sequencing about 80 individual clones. A high enrichment by human-specific sequences (about 95%) was demonstrated.

[The hormonal regulation of mRNA Na,K-ATPase expression in rat kidneys in postnatal ontogeny].

A study was made of effects of aldosterone, aldosterone+dexamethasone, and aldosterone+spironolactone on Na,K-ATPase mRNA expression in renal cortex of adult and 10 day old rats, when kidney is not sensitive to the hormone injection. It is shown that hormonal induction of synthesis of Na,K-pump mRNA occurs in the early postnatal period apart from mineral corticoid receptors. It seems probable that aldosterone exerts its action in 10 day old rats by interaction with glucocorticoid receptors inducing synthesis of different amounts of alpha- and beta-subunits of Na,K-ATPase.
