The identification of autoantibodies to tumor cell proteins by proteomics approaches has great potential impact on cancer biomarker discovery. The humoral immune response represents a form of biological amplification of signals that are otherwise weak due to very low concentrations of antigen, especially in the early stages of cancers. In addition, proteomics can detect immunoreactivity directe...

Chondrosarcoma is the third most common primary bone cancer, requiring surgical resection. However, differentiation of low-grade chondrosarcoma (grade 1) from enchondroma that is benign and only requires regular follow-up is one of the most frequent diagnostic dilemmas facing orthopedic oncologists in clinical management. Although multiple techniques are applied to make the distinction, immunoh...

Few strong and consistent associations have arisen from observational studies of dietary consumption in relation to chronic disease risk. Measurement error in self-reported dietary assessment may be obscuring many such associations. Attempts to correct for measurement error have mostly used a second self-report assessment in a subset of a study cohort to calibrate the self-report assessment use...

Follicular adenoma is a type of benign and encapsulated nodule in the thyroid gland, but some adenomas have the potential to progress to follicular carcinoma. Therefore, it is important to monitor the state and progress of follicular adenoma in the clinic and discover drug development targets for the treatment of follicular adenoma to prevent its worsening to follicular carcinoma. Currently, th...

We have developed a proteome database (DB), BiomarkerDigger (http://biomarkerdigger.org) that automates data analysis, searching, and metadata-gathering function. The metadata-gathering function searches proteome DBs for protein-protein interaction, Gene Ontology, protein domain, Online Mendelian Inheritance in Man, and tissue expression profile information and integrates it into protein data s...

While some potential biomarkers for ocular diseases have been reported, it is difficult to select a single biomarker that is most important in each ocular disease. After reviewing multiple biomarker studies conducted on small sample subgroups, we concluded that newer analysis techniques may result in different and more specific findings. While progress has been made in developing various omics ...

the eukaryotic complexity involves the expression and regulation of genes via rna-dna, rna-rna, dna-protein and rna-protein interactions. recently, the role of rna molecules in the regulation of genes in higher organisms has become more evident, especially with the discovery that about 97% of the transcriptional output in higher organisms are represented as noncoding rnas: rrna, snornas, trna, ...

the aim of this study is to determine whether there is a role of podoplanin and glutathione s-transferases t1 (gst-t1) expression in laryngeal squamous cell carcinoma. the study was completed with 33 patients and gene expression analysis was performed by qrt–pcr. the podoplanin and gst-t1 expression patterns were analyzed to determine their correlation with clinicopathologic parameters of laryn...

Protein profiling using SELDI-TOF-MS has gained over the past few years an increasing interest in the field of biomarker discovery. The technology presents great potential if some parameters, such as sample handling, SELDI settings, and data analysis, are strictly controlled. Practical considerations to set up a robust and sensitive strategy for biomarker discovery are presented. This paper als...
