In rubella virus-infected cells, genomic 40S and subgenomic 24S RNAs are present in the cytoplasm of infected cells. However, encapsidation by rubella virus capsid protein is specific for 40S genomic RNA. As a first step toward understanding the assembly of rubella virus nucleocapsid at the molecular level, the interaction between capsid protein and genomic(More)
Transgenic animals expressing genes capable of repairing DNA may be a valuable tool to study the effect of DNA-damaging agents on tissuespecific carcinogenesis. For this reason, we constructed a chimeric gene consisting of the promoter-regulatory region of the phosphoenolp) ruvate carboxykinase (GTP) (EC (PEPCK) gene linked to the Escherichia coli(More)
This study evaluated the effect of 3-hydroxyflavone (a flavonoid having hydroxyl group at 3 carbon position) on embryos using parthenogenetic activation (PA) and cloned pig embryos as model system. There was no evidence for embryo toxicity of 3-hydroxyflavone in a wide concentration range of 1-100 μM. On the contrary, 3-hydroxyflavone significantly improved(More)
The emerging class of B cell superantigens includes HIV-1 gp120, which binds to many members of the V(H)3 Ig gene family. The present study addresses the structural features of V(H)3 antibodies conferring gp120 binding activity using a panel of recombinant full-length and Fab Ig proteins. Binding activity was fully conferred by the Fab portion of the Ig(More)
Background: B-cell translocation gene 2 (BTG2) belongs to antiproliferative (ARPO) gene family and the expression of BTG2, human ortholog of rat PC3 and mouse TIS21 gene, has been shown to render cancer cells more sensitive to doxorubicin treatment by upregulating MnSOD expression without regulating any other reactive oxygen species (ROS) scavenging(More)
Several studies have indicated that the necessity for co-receptor engagement during T cell activation depends on the avidity of the TCR-MHC interaction under investigation. Using thymocytes, naive T cells and a long-term T cell line isolated from 2B4 TCR transgenic mice, we have examined the role of the CD4 co-receptor on cells expressing the identical TCR(More)
