Major technological advances have made proteomics an extremely active field for biomarker discovery and validation in recent years. These improvements have lead to an increased emphasis on larger scale, faster and more efficient methods for protein biomarker discoveries in human tissues, cells and biofluids. However, most current proteomic methodologies for biomarker discovery and validation ar...

For a diallelic marker locus, the parental-asymmetry test (PAT) based on case-parents trios and its extensions to accommodate incomplete unclear families (1-PAT and C-PAT) are simple and powerful approaches to test for parent-of-origin effects. However, haplotype analysis is generally regarded as advantageous over single-marker analysis in genetic study of common complex diseases. This is mainl...

The advances in mass spectrometry-based proteomics technologies have enabled the generation of global proteome data from tissue or body fluid samples collected from a broad spectrum of human diseases. Comparative proteomic analysis of global proteome data identifies and prioritizes the proteins showing altered abundances, called differentially expressed proteins (DEPs), in disease samples, comp...

Increased research efforts are currently focusing on Atlantic cod (Gadus morhua) and its significance for monitoring the contaminant situation in marine environments. Polycyclic aromatic hydrocarbons (PAHs) are well known toxic and carcinogenic compounds, thus continuous monitoring is required to ensure ecosystem sustainability and human food safety. A sensitive biomarker of PAH exposure in hum...

during the past two decades, a variety of serum or cerebrospinal fluid (csf) biochemical markers in daily clinical practice have been recommended to diagnose and monitor diverse diseases or pathologic situations. it will be essential to develop a panel of biomarkers, to be suitable for evaluation of treatment efficacy, representing distinct phases of injury and recovery and consider the tempora...

introduction: hydatid cyst disease is caused by the protoscolices of echinococcus granulosus. alkaline phosphatase (alp) enzyme is required for metabolism, physiology, immunology, and nutrients absorption in parasite. the aim of this study was to compare the level of alp activity (as a pathological biomarker) in hydatid cyst protoscolices (hcp) with that of sheep liver tissue and to determine t...

PURPOSE Chronic allograft nephropathy (CAN) remains the leading cause of renal graft loss after the first year following renal transplantation. This study aimed to identify novel urinary proteomic profiles, which could distinguish and predict CAN in susceptible individuals. EXPERIMENTAL DESIGN The study included 34 renal transplant patients with histologically proven CAN and 36 patients with ...

in 2006 to provide researchers engaged in biomarker discovery with a high-throughput, high-sensitivity approach to protein expression profiling. The ProteinChip system incorporates chip-based applications with top-down mass spectrometry (MS) for protein profiling, an area of research that has typically relied on more conventional approaches such as 2-D gel electrophoresis. Since its introductio...

It is becoming increasingly clear that no single marker will have the sensitivity and specificity necessary to be used on its own for diagnosis/prognosis of tumors. Interpatient and intratumor heterogeneity provides overwhelming odds against the existence of such an ideal marker. With this in mind, our laboratory has been applying a long term systematic approach to identify multiple biomarkers ...
