Infection with SIVmac251 in some rhesus monkeys (Macaca mulatta) leads to B-cell non-Hodgkin's lymphomas (B-NHL) clinically similar to that of HIV-infected AIDS patients. To further characterize the SIV-associated B-NHL we have generated genetic profiles of malignant cells by subtractive hybridization and Northern blot analysis. We have analyzed 21 clones(More)
DNA polymerase iota (Pol iota) of mammals is a member of the Y family of DNA polymerases. Among many other genome caretakers, these enzymes are responsible for maintaining genome stability. The members of the Y-family DNA polymerases take part in translesion DNA synthesis, bypassing some DNA lesions, and are characterized by low fidelity of DNA synthesis. A(More)
Two-year experiments were performed to evaluate the neurotrophic effect of hypoxia-inducible factors (vascular endothelial growth factor and angiogenin) expressed in recombinant human adenoviruses in amyotrophic lateral sclerosis. Randomized placebo-controlled trial demonstrated safety and good tolerability of the recombinant antiviral drugs. The life span(More)
Transgenic silkworms (Bombyx mori L.) were obtained by microinjection of plasmid pPrC-LTR1.5, which carris 1.5 DNA copies of Rous sarcoma virus (RSV) long terminal repeats (LTRs) inserted in the vector pBR322. The transgene was transmitted over the three generations obtained up to now. Most of the exogenous DNA failed to integrate into the genome and(More)
The effects of pub gene on proliferation and initial stages of differentiation of embryonic mouse stem cells were studied in vitro. To this end we used enhanced expression of human pub gene (hpub) and suppression of expression of mouse endogenous pub gene with RNA-interference in embryonic stem cells. Proliferative activity of genetically modified(More)
Transient expression of recombinant plasmids carrying the lacZ gene under the control of either bovine alphaS1-casein gene tissue-specific promoter-enhancer region or highly homologous goat alphaS1-casein gene promoter-enhancer region with supplementary regulatory sequences of the goat gene were studied in Misgurnus fossilis L. loach embryos. It has been(More)
New functions of well-known genes have been revealed frequently. A new example is described in this report. Earlier we have detected an up-regulation of expression of the mitochondrial 16S rRNA gene in non-Hodgkin's lymphomas. Here we demonstrate that the human mitochondrial 16S rRNA gene encodes a potential oncopeptide, Humanin described recently. This(More)
Diffuse large B-cell lymphoma (DLBCL) is more prevalent and more often fatal in HIV-infected patients and SIV-infected monkeys compared to immune-competent individuals. Molecular, biological, and immunological data indicate that virus-associated lymphomagenesis is similar in both infected hosts. To find genes specifically overexpressed in HIV/SIV-associated(More)
Several novel, differentially transcribed genes were identified in one centroblastic and one immunoblastic HIV-associated B-cell non-Hodgkin's lymphoma (B-NHL) by subtractive cloning. In both lymphomas, we detected an upregulated transcription of several mitochondrial genes. In the centroblastic B-NHL, we found a high level transcription of nuclear genes(More)
In the present research, we have studied an influence of enhanced expression TRIM14 on alphavirus Sindbis (SINV, Togaviridae family) infection. In the HEK293 cells transfected with human trim14 gene (HEK-trim14), SINV yield after infection was decreased 1000-10,000 times (3-4 lg of TCD50/ml) at 24 h p.i. and considerably less (1-2 lg of TCD50/ml) at 48 h(More)
