viruses
The transposed genome was then used to transfect Sf21 insect cells, and a library of mutant viruses capable of expressing green fluorescence protein was obtained.
      
Two mutant viruses, B9F and Li6A were isolated, and the sites of transposon insertion were determined to be within the coding regions of the 94k and p10 genes, respectively.
      
Foamy viruses (FVs) have broad cellular tropism infecting vertebrates from fish to human being, which indicates that Env protein has a high capability for membrane fusion.
      
Many recent findings have demonstrated that viruses can also encode their own miRNAs.
      
This article introduces the miRNAs encoded by viruses and reviews the advances of the interaction of the mammalian host miRNAs and viral infection.
      
The recent progress in molecular biology techniques made it possible to obtain the fundamental data on the detection of latent viruses in different insect species as well as on the mechanism of latent infection induction, which are reviewed below.
      
Ecology of Allochthonous and Autochthonous Viruses in the Black Sea by O.
      
They have been recognized in all pro- and eukaryotic organisms and also in pox and herpes viruses.
      
All eukaryotic organisms have apoptosis inhibitors, which might be introduced by viruses.
      
The action of proteinase inhibitors from plants upon the enzymes from pathogenic microorganisms and viruses is reviewed.

Analysis of interactions of DNA polymerase β and reverse transcriptases of human immunodeficiency and mouse leukemia viruses wit
      
Over many decades, viruses have proven their invaluable and pioneering role as tools in molecular genetics.
      
These cells are involved in distribution and persistence of viruses in the organism and also influence the regulation of immune reactions.
      
Specific biochemical features of replication of clinical influenza viruses in human intestinal cell culture
      
Influenza A viruses isolated from the respiratory tract of patients with influenza were cultured in human intestinal epithelium cells (CACO-2 line).
      
The CACO-2 cells were found to be 100-fold more susceptible to the clinical viruses than MDCK cells and chicken embryos.
      
The increased tropism to the human CACO-2 cells correlated with higher adsorption of the clinical viruses on cellular receptors.
      
Thus, clinical influenza viruses are shown to possess a specific mechanism of sorption and entry into human epithelial cells, which is responsible for their higher tropism to human cells and is unlike such a mechanism in canine cells.
      
Expression of the STAT1 gene belonging to the group of interferon-regulated genes was analyzed in cervical tumors and cell lines harboring the genome of human papilloma viruses (HPV) of so-called high risk group.
