An accurate biomarker for the follow-up of women positive for human papillomavirus type 16 (HPV16) DNA may improve the efficiency of cervical cancer prevention. Previously, we analyzed all 113 HPV16 CpGs in cervical cytology samples and discovered differential methylation at different stages of premalignancy. In the current study, we identified a methylation biomarker consisting of a panel of 1...

NMR-based metabolomics has shown considerable promise in disease diagnosis and biomarker discovery because it allows one to nondestructively identify and quantify large numbers of novel metabolite biomarkers in both biofluids and tissues. Precise metabolite quantification is a prerequisite to move any chemical biomarker or biomarker panel from the lab to the clinic. Among the biofluids commonly...

cancer stem cells (csc) are the tumor-associated cells existed within tumors or hematological cancers which share characteristics similar to normal stem cells. the common characteristics of a normal stem cell and a csc are their differentiation capacity and self-renewal in tumors. the expression pattern of csc markers differs depending on the type and location of cancers. cd molecules are proba...

Background To assess the value of serological biomarker testing as a substitute for esophagogastroduodenoscopy (EGDS) in pre-operative assessment of patients referred for bariatric surgery. Methods Sixty-five obese patients with a mean age of 43 years (range: 21-65) and a mean body mass index (BMI) of 44 (range: 36-59) were studied. The patients were tested with a four-biomarker panel: pepsin...

Pancreatic adenocarcinoma is a highly aggressive cancer, with a median patient survival of less than one year. Clinically useful biomarkers capable of accurately assessing prognosis, as well as response to therapy, are urgently needed. At the 2014 ASCO Annual Meeting, Maus et al. (Abstract #e15199) and Neuzillet et al. (Abstract #e15200) present data on use of c-met as a prognostic biomarker, a...

Using photogenerated glycan arrays, we characterized a large panel of synthetic carbohydrates for their antigenic reactivities with pathogen-specific antibodies. We discovered that rabbit IgG antibodies elicited by Bacillus anthracis spores specifically recognize a tetrasaccharide chain that decorates the outermost surfaces of the B. anthracis exosporium. Since this sugar moiety is highly speci...

INTRODUCTION The water proton Apparent Diffusion Coefficient (ADC) has been proposed as a biomarker of the non-viable fraction in tumours. Our aim was to evaluate the correlation between ADC and histopathology in a diverse panel of human tumour xenografts commonly used in preclinical drug efficacy evaluation. We hypothesised that ADC would correlate with histologically quantified necrosis and o...

colorectal cancer remains one of the major cancer- related deaths despite progress in the treatment during past decades. detection of disease at earlier stages reduces its mortality. the aim of current study was to investigate expression of cytokeratin 19 (ck19), cytokeratin 20 (ck20) and guanylyl cyclase c (gcc) mrna in peripheral blood of non- metastatic colorectal cancer patients which may r...

PURPOSE To identify a panel of epigenetic biomarkers for accurate bladder cancer (BlCa) detection in urine sediments. EXPERIMENTAL DESIGN Gene expression microarray analysis of BlCa cell lines treated with 5-aza-2'-deoxycytidine and trichostatin A as well as 26 tissue samples was used to identify a list of novel methylation candidates for BlCa. Methylation levels of candidate genes were quant...

RESEARCH DESIGN AND METHODSdWe evaluated 3,019 JHS participants (mean age, 54 years; 64%women) with measurements for seven biomarkers representing inflammation (high-sensitivity C-reactive protein [CRP]), adiposity (leptin), natriuretic pathway (B-natriuretic peptide [BNP]), adrenal pathway (cortisol and aldosterone), and endothelial function (endothelin and homocysteine).We related the biomark...
