Description…

The GPX3 gene product, glutathione peroxidase 3, is a member of the glutathione peroxidase family. Family members are involved in the detoxification of hydrogen peroxide. Glutathione peroxidase is one of the most important antioxidant enzymes in humans. The GPX3 protein is one of only a few proteins known in higher vertebrates to contain selenocysteine, which occurs at the active site of glutathione peroxidase and is coded by UGA, that normally functions as a translation termination codon. Selenoprotein mRNAs contain a conserved secondary structure in the 3' UTR that is required for the distinction of UGA stop from UGA selenocysteine. The selenocysteine insertion sequence (SECIS) is around 60 nt in length and adopts a hairpin structure which is sufficiently well-defined and conserved to act as a computational screen for selenoprotein genes.

New Funding Opportunity: Biomarker Development Laboratories for the Early Detection Network: Applications Due May 23

Update: Pre-application webinar information now available.

The National Cancer Institute's Division of Cancer Prevention has released a new funding opportunity to solicit organ-specific applications for Biomarker Developmental Laboratories (BDLs), one of the four scientific units of the recently funded Early Detection Research Network (EDRN). The EDRN is a national infrastructure funded to discover, develop, and validate biomarkers for risk assessment, detection, and molecular diagnosis and prognosis of early cancer. BDLs are responsible for the discovery, development, characterization, and testing of new, or the refinement of existing, biomarkers and biomarker assays for risk assessment, detection, and molecular diagnosis and prognosis of cancers.

The existing BDLs are primarily focused on ovary and gastrointestinal cancers. The proposed BDLs (to be supported under this funding opportunity) should be focused on one or more of the following cancers: breast, prostate and other genitourinary organs, or lung. In addition, cancers with rapidly rising incidence rates, e.g., endometrial, hepatocellular, kidney, thyroid, oropharyngeal cancers, and/or cancers with unique etiology, e.g., mesothelioma, will be considered.

The newly funded units of the Early Detection Research Network will be announced later in April. Successful applicants have already been notified. Those researchers who were not successful during the last round of applications are encouraged to apply to this opportunity.
