background : glioblastoma multiforme (gbm) or grade iv astrocytoma is the most common and lethal adult malignant brain tumor. several of the molecular alterations detected in gliomas may have diagnostic and/or prognostic implications, proteomics has been widely applied in various areas of science, ranging from the deciphering of molecular pathogen nests of discuses. method: we extracted protein...

The increase in sequencing capacity led to a new wave of metagenomic projects, enabling and setting the prerequisite for the application of environmental proteomics technologies. This review describes the current status of environmental proteomics. It describes sample preparation as well as the two major technologies applied within this field: two-dimensional electrophoresis-based environmental...

proteins are fundamental components of cells which mediate many essential biological processes. proteomics is a rapidly growing field for the study of proteome, the protein complement expressed by the genome of an organism or cell type. the large-scale analysis of proteins leads to a more comprehensive view of molecular and cellular pathways that improves the overall understanding of the comple...

To facilitate genome-based representation and analysis of proteomics data, we developed a new bioinformatics framework, proBAMsuite, in which a central component is the protein BAM (proBAM) file format for organizing peptide spectrum matches (PSMs)(1) within the context of the genome. proBAMsuite also includes two R packages, proBAMr and proBAMtools, for generating and analyzing proBAM files, r...

Proteomics approaches enable interrogation of large numbers of proteins to provide a more comprehensive understanding of biological systems. High throughput proteomics typically utilizes liquid chromatography – mass spectrometry technology for data acquisition. Bioinformatic analysis tools are essential to manage and mine resulting high volume proteomics data sets. Data analysis is a current bo...

High-density lipoprotein (HDL) is a lipid and protein complex that consists of apolipoproteins and lower level HDL-associated enzymes. HDL dysfunction is a factor in atherosclerosis and decreases patient survival. Mass spectrometry- (MS-) based proteomics provides a high throughput approach for analyzing the composition and modifications of complex HDL proteins in diseases. HDL can be separated...

Proteomics is defined as the system-wide characterization of all the proteins in an organism in terms of their sequence, localization, abundance, post-translational modifications, and biomolecular interactions. Modern proteomic investigations are increasingly quantitative and comprehensive [1]. Examples include the relative quantification of over 4,000 proteins in haploid and diploid yeast, whi...

background: transforming growth factor-beta (tgf-β) activation appears to be crucial for tissue injury in diabetic nephropathy (dn). fibromodulin, the small leucine-rich proteoglycan, has been proposed to be the potent tgf-β modulator. in this study, the therapeutic effects of fibromodulin in the kidneys of streptozotocin (stz)-induced diabetic rats were investigated. methods: diabetic rats rec...

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...
