Biomarker Bulletin: June 20, 2011

Biomarker Bulletin is an occasionally recurring update of news focused on biomarkers aggregated at BiomarkerCommons.org. Biomarkers are physical, functional or biochemical indicators of normal physiological or disease processes. The individualization of disease management — personalized medicine — is dependent on developing biomarkers that promote specific clinical domains, including early detection, risk, diagnosis, prognosis and predicted response to therapy.

  • Results of Highly Cited Biomarker-disease Associations Often Overestimated

    Although new biomarkers are regularly proposed to serve as potential determinants of disease risk, prognosis or response to treatment, many markers only get evaluated in one or a small number of studies. A review in the June 1st edition of JAMA reports that the results of highly cited biomarker-disease associations that appear in major journals are often substantially overestimated, with effect sizes exceeding those found when the association is evaluated in larger studies.

  • Roche, UCLA Announce Biomarker Research Collaboration

    Roche said last week that it will provide UCLA scientists with a range of genomics tools as part of a research collaboration to study stem cells and cancer, and for the development of new predictive biomarkers for future therapeutics and diagnostics for a host of diseases.

  • Stemina Biomarker Discovery, Children’s Hospital of Orange County Sign Agreement to Study Autism

    Stemina Biomarker Discovery announced on Friday that it has signed an agreement with Children’s Hospital of Orange County (CHOC) to conduct a study of neural cells from autistic patients using Stemina’s proprietary biomarker discovery platform.

  • Indiana CTSI, GVK Biosciences Partner to Provide National Access to Biomarkers Database

    The Indiana Clinical and Translational Sciences Institute (CTSI), a statewide collaboration of Indiana University, Purdue University and the University of Notre Dame, as well as public and private partnerships, which facilitates the translation of scientific discoveries in the lab into clinical trials and new patient treatments in Indiana and beyond, announced on Friday that they have partnered with GVK Biosciences. GVK Biosciences will provide researchers across the United States access to their clinical biomarker database.

  • Biomarker Briefs: June 13, 2011

    Biomarker Briefs is an occasionally recurring series highlighting particularly interesting articles on biomarkers and/or personalized medicine. This edition includes articles on personalized medicine, a new online tool for analyzing personal genome data, a blood test for depression, and a kidney injury biomarker initiative.

Genetic Risk Factor for Peanut Allergies Identified

It is difficult to find a school, camp or other facility catering to children these days that is not nut free. The prevalence of peanut allergies in preschool and school age children in the UK, the US and Canada is between 1.2 – 1.6%, which is about twice the rate at which it occurs in adults in these countries. Nut allergies, especially peanut allergies, are scary. And although they have been on the rise, no one really knows why. Researchers in Scotland recently reported in The Journal of Allergy and Clinical Immunology that mutations in the gene for filaggrin, a protein found in skin, are a “significant risk factor for peanut allergy” [1].

  • MedTrust Online, Avantra Biosciences Collaborate to Involve Clinicians in Assay Development

    MedTrust Online and Avantra Biosciences recently announced that they will collaborate on involving clinicians in early-stage development of molecular diagnostic assays to run on Avantra Biosciences’ QPDx multiplex immunoassay system.

  • Biomarker May Prove Useful for Diagnosing Knee Injury

    Researchers from Stanford University School of Medicine recently discovered a biomarker that may enable doctors to diagnose a common form of knee injury. The study, published in the Journal of Bone and Joint Surgery, has identified a specific protein complex in the knee fluid of patients with painful meniscal tears.

  • OncoTrack Launches Search for Novel Genomic Cancer Diagnostics

    A new European consortium called OncoTrack has just launched one of Europe’s largest collaborative academic-industry research projects to develop and assess novel approaches for the identification of new biomarkers for colon cancer. The five year project, Methods for systematic next generation oncology biomarker development, brings together top European academic researchers with a wide range of expertise and partners them with pharmaceutical companies.

  • Discovery of Diagnostic and Prognostic Prostate Cancer Serum Biomarkers Guided by Cancer Genetics

    An interdisciplinary team of researchers from ETH Zurich, University Hospital Zurich and the Cantonal Hospital of St. Gallenhas has defined biomarkers in patients’ blood serum that indicates the presence of prostate cancer. The method used has the potential to be applied to other types of tumors.

  • SciClips Launches Diagnostic and Prognostic Biomarker Database

    In the era of personalized medicine, drugs will be targeted to patients based upon his or her unique genetic profile. Biomarkers are a critical component for tailoring treatments to individual patients. Biomarkers will be used as tools for target discovery, noninvasive early stage diagnosis of diseases, for evaluation of mode of action of a drug, dose determination and prediction of the drug effect. They will accelerate not only the development of effective and non-toxic drugs but also help in monitoring patient health and response to treatment.

Abnormal Heart Rate Turbulence May Predict Heart Disease

According to a study in the February 15 edition of the Journal of Cardiovascular Electrophysiology, abnormal heart rate turbulence is associated with an increased risk of heart disease death in otherwise older, low-risk individuals [1]. Additional studies need to be done in order to understand whether this potential biomarker will be a clinically valuable tool.
