[ 1 ] - Activation of calcium/calmodulin-dependent kinase II following bovine rotavirus enterotoxin NSP4 expression

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...

[ 2 ] - Surface protein mutations in chronic hepatitis B patients who received hepatitis B vaccine therapy

Objective (s):The aim of this study was to determine the correlation between vaccine therapy and appearance of mutations in hepatitis B surface antigen (HBsAg)-positive chronic hepatitis B virus (HBV) patients. Materials and Methods: 16 patients received the HBV vaccine and another 16 individuals from the control group did not. The surface gene was amplified and directly sequenced from samples...

[ 3 ] - Rotavirus NSP4 protein as a viral biotoxin selectively promotes cytotoxicity

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...
