background: analysis of many proteins produced during the transition into the stationary phase and under stress conditions (including starvation stress) demonstrated that a number of novel proteins were induced in common to each stress and could be the reason for cross-protection in bacterial cells. it is necessary to investigate the synthesis of these proteins during different stress condition...
Background: Radiotherapy is an effective and important therapeutic method for breast cancer, but at the same time it has a radiation-induced bystander effect on normal tissue around the tumor. Repair of double-strand breaks (DSBs) by normal cells can reduce the extent of damage caused by this effect. Caveolin-1 (Cav-1) is an important regulatory molecule in cell signal transduction. However, th...
Introduction: Cerebral ischemia-reperfusion causes complex pathological mechanisms that lead to tissue damage, such as neuronal apoptosis. Usnic acid is a secondary metabolite of lichen and has various biological properties including antioxidant and anti-inflammatory activities. This study aimed to investigate the neuroprotective effects of usnic acid on apoptotic cell death and apoptotic-relat...
a proteomic approach was conducted to further understand the mechanism of plant responses to salinity in hordeum bulbosom. three-week-old seedlings were treated with 300 mm of nacl for 21 days. total proteins of fourth leaf were extracted and separated by two-dimensional gel electrophoresis. more than 500 protein spots were reproducibly detected, including 46 spots that were up-regulated and 16...
The production of biotechnological drug proteins plays an important role against disease. The process of producing drug recombinant proteins is not a direct path, because it requires a lot of work and on the other hand, one of the important and significant aspects in the production of proteins is the discussion of their stability and solubility during the expression and purification process. Pr...
background: lipopolysaccharides (lpss) and several antigenic proteins of brucella have been considered for preparation of diagnostic reagents and subunit vaccines. the objective of this study was to identify and compare immunogens of b. abortus s19 which induce humoral immune responses in human, goat and rabbit. material and methods: the bacterial whole cell extract was prepared in extraction...
background: viscerotropic leishmaniasis caused by leishmania tropica poses a significant problem in the diagnosis and treatment management. since differential gene expression is more important in outcome of the infection, we employed proteomic approach to identify potential proteins involved in visceralization of l. tropica . methods: the proteomes profiling of l. tropica isolated from cutan...
Platinum is a metallic element, which may react with our cellular component through its involvement in cancer chemotherapy medications. Cisplatin is one of the most useful antineoplastic drugs against human ovarian carcinoma, which has the central element of platinum in its structure. The nature of chemical interaction between platinum and cellular macromolecules is yet to be understood. We exa...
