This review highlights genes, proteins and subcellular mechanisms, recently shown to influence cortical neuronal migration. A current view on mechanisms which become disrupted in a diverse array of migration disorders is presented. The microtubule (MT) cytoskeleton major player migrating neurons. Recently, variable impacts MTs have been revealed different cell compartments. Thus there are multi...

Salmonella Typhi is the primary causative agent of typhoid fever; an acute systemic infection that leads to chronic carriage in 3–5% individuals. Chronic carriers are asymptomatic, difficult treat and serve as reservoirs for outbreaks. Understanding factors contribute key development novel therapies effectively resolve fever. Herein, although we observed no distinct clustering isolates via phyl...

The dimorphic fungal pathogen Histoplasma capsulatum causes respiratory and systemic disease. Within the mammalian host, pathogenic Histoplasma yeast infect, replicate within, and ultimately kill host phagocytes. Surprisingly, few factors have been identified that contribute to Histoplasma virulence. To address this deficiency, we have defined the constituents of the extracellular proteome usin...

BACKGROUND Protein secretion is a fundamental process in all living cells. Gluconeogenic enzymes are secreted when Saccharomyces cerevisiae are grown in media containing low glucose. However, when cells are transferred to media containing high glucose, they are internalized. We investigated whether or not gluconeogenic enzymes were associated with extracellular vesicles in glucose-starved cells...

esophagus cancer is the eighth most common cancer worldwide and particularly high in an area extending from the southern border of the caspian sea in iran across central asia to china. since information about this mysterious disease is poor, proteomics may be solving this enigma. altering gene expression in cancer cell is a remarkable indicator can be detected by proteomics techniques and bioin...

Sustainable development in the bio-treatment of large-scale biomass bulks requires high performance enzymes adapted to extreme conditions. An extracellular keratinolytic extract was obtained from the culture broth of a halotolerant strain of Salicola marasensis. Keratin hydrolyzing activity of the concentrated enzyme extract was observed on a 100 mg of pretreated feather waste...

Diabetic retinopathy (DR) is a retinal disease representing one of the main causes vision loss in developed countries. In early stage DR, disruption blood barrier (BRB) observed, and it will lead to vascular permeability visual impairment. Therefore, protection against breakdown BRB may be useful strategy for prevention DR. Matrix metalloproteinases (MMPs) plays an important role degradation ex...

To analyse the proteome of Bacillus subtilis extracellular proteins, extracellular protein samples were prepared from culture media (minimal medium containing 0.4% glucose) of parental B. subtilis 168, a secA-temperature sensitive mutant and an ffh conditional mutant, and examined by two-dimensional gel electrophoresis. Approximately 100 to 110 spots were visualized in a gel of B. subtilis 168 ...

Extracellular proteins of Cryptococcus neoformans are involved in the pathogenesis of cryptococcosis, and some are immunoreactive antigens that may potentially serve as candidates for vaccine development. To further study the extracellular proteome of the human fungal pathogen Cry. neoformans, we conducted a proteomic analysis of secreted and cell wall-bound proteins with an acapsular strain of...
