Small molecule inhibitors of protein kinases are key tools for signal transduction research and represent a major class of targeted drugs. Recent developments in quantitative proteomics enable an unbiased view on kinase inhibitor selectivity and modes of action in the biological context. While chemical proteomics techniques utilizing quantitative mass spectrometry interrogate both target specif...

nephrotic syndrome is the commonest glomerular disease. typical symptoms could be proteinuria, low serum albumin and oedema. the mechanism of proteinuria in nephrotic syndrome is a defective glomerular filtration barrier. renal biopsy is the gold standard for diagnosis of nephrotic syndrome currently which is invasive and based on histopathological features, therefore it seems to be necessary to...

introduction: during the last 3 decades, human is exposed to extremely low frequency electromagnetic fields (elf-emf) emitted by power lines and electronic devices. it is now well accepted that elf-emf are able to produce a variety of biological effects, although the molecular mechanism is unclear and controversial. investigation of different intensities effects of 50 hz elf-emf on cell morphol...

Breast cancer in men (MBC) is an uncommon malignancy and accounts for only 1% of all diagnosed breast cancers. By using genomic and transcriptomic approaches, researchers have been able to expand our insight into the genetic basis of breast cancer, by providing new biomarkers. We currently know that gene analysis by itself does not show the complete picture. Along with the genomic approach, pro...

Hectares of genetically modified (GM) crops have increased exponentially since 1996, when such crops began to be commercialized. GM biotechnology, together with conventional breeding, has become the main approach to improving agronomic traits of crops. However, people are concerned about the safety of GM crops, especially GM-derived food and feed. Many efforts have been made to evaluate the uni...

Publication in 1975 by Patrick O'Farrell of a procedure to separate the proteins of Escherichia coli in a two-dimensional array on polyacrylamide gels marked the birth of the field now called proteomics. Although O'Farrell's contribution was soon to have wide ranging effects on research in many fields, the initial impact was greatest in the arena of whole cell physiology. Refinements and amplif...

Functional proteome analysis is not restricted to the sequence information but includes the broad spectrum of structural modifications and quantitative changes of proteins to which they are subjected in different tissues and cell organelles and during the development of an organism. Cell biology has provided the means required for the analysis of the composition and properties of purified cellu...

background: today, despite the many advances in early detection of diseases, cancer patients have a poor prognosis and the survival rates in them are low. recently, microarray technologies have been used for gathering thousands data about the gene expression level of cancer cells. these types of data are the main indicators in survival prediction of cancer. this study highlights the improvement...

After the genomic era, proteomic corresponds to a wide variety of techniques that study the protein content of cells, tissue, or organism and that allow the isolation of protein of interest. It offers the choice between gel-based and gel-free methods or shotgun proteomics. Applications of proteomic technology may concern three principal objectives in several biomedical or clinical domains of re...

The availability of complete genome sequences for a large number of pathogenic organisms has opened the door for large-scale proteomic studies to dissect both protein expression/regulation and function. This review highlights key proteomic methods including two-dimensional gel electrophoresis, reference mapping, protein expression profiling and recent advances in gel-free separation techniques ...
