Abstract Background and Aims: The number of new cancer cases with considerable mortality is increasing worldwide. Since the inability of current therapies in treatment of patients and prevention the progress of tumors with fewer side effects, implementation of new methods is needed. Gene therapy has widespread systemic cytotoxic effects against tumor cells. Rotavirus NSP4 has been shown to...

rotavirus nonstructural glycoprotein nsp4 can induce diarrhea in newborn mice. it has been suggested that nsp4 may be a key determinant for rotavirus pathogenesis and a target for vaccine development. in order to study the biological and morphological role of nsp4 a large amount of the purified protein and antibody against it are required. simian rotavirus sa11 was propagated in bscl cell, puri...

The NSP4 protein of a simian rotavirus was reported to induce diarrhea following inoculation of mice. If NSP4 is responsible for rotavirus diarrhea in humans, attenuation of a human rotavirus may be reflected in concomitant mutations in the NSP4 gene. After 33 passages in cultured monkey kidney cells, a virulent human rotavirus (strain 89-12) was found to be attenuated in adults, children, and ...

Nonstructural protein 4 (NSP4), encoded by group A rotavirus genome segment 10, is a multifunctional protein and the first recognized virus-encoded enterotoxin. The NSP4 gene has been sequenced, and five distinct genetic groups have been described: genotypes A-E. NSP4 genotypes A, B, and C have been detected in humans. In this study, the NSP4-encoding gene of human rotavirus strains of differen...

A rotavirus (RV) nonstructural protein, NSP4, has recently been proposed to function as an enterotoxin in the pathogenesis of RV diarrhea. The role of NSP4 in the pathogenesis of RV diarrhea was examined by infecting cystic fibrosis transmembrane conductance regulator (CFTR) knockout mice with virulent murine RV and by comparing deduced amino acid sequences of RV gene 10 encoding NSP4 from thre...

Rotavirus nonstructural glycoprotein NSP4 can induce diarrhea in newborn mice. It has been suggested that NSP4 may be a key determinant for rotavirus pathogenesis and a target for vaccine development. In order to study the biological and morphological role of NSP4 a large amount of the purified protein and antibody against it are required. Simian rotavirus SA11 was propagated in BSCl cell,...

Objective(s): The rotavirus nonstructural protein 4 (NSP4) is responsible for the increase in cytoplasmic calcium concentration through a phospholipase C-dependent and phospholipase C-independent pathways in infected cells. It is shown that increasing of intracellular calcium concentration in rotavirus infected cells is associated with the activation of some members of protein kinases family su...

Rotavirus (RV)-infected piglets are presumed to be latent sources of heterologous RV infection in humans and other animals. In RVs, non-structural protein 4 (NSP4) is the major virulence factor with pleiotropic properties. In this study, we analyzed the nsp4 gene from porcine RVs isolated from diarrheic and non-diarrheic cases at different levels of protein folding to explore correlations to di...
