The human immunodeficiency virus type 1 (HIV-1) reverse transcriptase (RT) is a heterodimer comprised of two structurally distinct subunits (p51 and p66). Since p51 and p66 are derived from the same coding region, subunit-specific structure-function studies of RT have been conducted exclusively by in vitro biochemical approaches. To study RT subunit function in the context of infectious virus, ...
Inefficient secretion of the human coagulation factor (hFVIII) in mammalian expression systems is one ofthe main causes of the hFVIII low expression level, attributed to its interaction with a chaperone known asBiP/GRP78. In order to improve secretion efficiency of the hFVIII, based on the higher secretion level of theporcine FVIII and analysis of the hFVIII A110 region, that ...
Low threshold Ca2+ currents mediated by T-type channels underlie burst spike activities of relay neurons in the thalamus. We have previously reported that knock-out mice for T-type channels show an enhanced nociceptive response to visceral pain, accompanied by an increase in tonic spikes in the absence of burst spikes in thalamic relay neurons. These results raised a possibility that T-type cha...
Background : Probiotics are defined as different microorganisms that may have positive effects on preventing or treatment of special pathologic conditions. Lactobacillus casei and L. paracasei as probiotics could induce the apoptosis in human cancer cells in vitro. Chronic myeloid leukemia is categorized as a blood cells cancer and the most common type of leukemia. The expression of mutant p53 ...
abstract in this study a greenhouse experiment was conducted to evaluate the role of acc deaminase enzyme on alleviation of salinity stress of canola plant. canola plants were exposed to pseudomonas fluorescens strain p12 which contains a rhizobacter capable of producing pseudomonas fluorescens in comparison with plants exposed to mutant pm12 unable to produce the required enzyme. the mutant wa...
Background:Tenofovir is among the first-line treatments for chronic hepatitis B (CHB) virus infection. We evaluated the efficacy of Tenofovir in the treatment of Iranian adult patients with CHB. Methods: In a retrospective study, we evaluated 154 HBsAg positive patients referred to Sadoughi hospital in Yazd-Iran for treatment ...
The structural requirements for the inhibitor activity of various furan carboxanilide derivatives against succinate dehydrogenase complex (SDC) activity in mitochondria of either wild or mutant strains of Ustilago maydis were investigated with the aid of Hansch QSAR analysis. It has been found that the inhibitor activity against both types of enzymes is best related to the ??? or ??M of th...
Objective(s): Adeno-associated virus type 2 (AAV2) vectors are widely used for both experimental and clinical gene therapy. A recent research has shown that the performance of these vectors can be greatly improved by substitution of specific surface-exposed tyrosine residues with phenylalanines. In this study, a fast and simple method is presented to generate AAV2 vector helper plasmids encod...
