New Effort to Identify Parkinson’s Biomarkers

Last month, the National Institutes of Health announced a new collaborative initiative that aims to accelerate the search for biomarkers — changes in the body that can be used to predict, diagnose or monitor a disease — in Parkinson’s disease, in part by improving collaboration among researchers and helping patients get involved in clinical studies. As part of this program, launched by the National Institute of Neurological Disorders and Stroke (NINDS), part of the NIH, Clemens Scherzer, MD, a neurologist and researcher at Brigham and Women’s Hospital (BWH), was awarded $2.6 million over five years to work on the development of biomarkers and facilitate NINDS-wide access to one of the largest data and biospecimens bank in the world for Parkinson’s available at BWH. This NINIDS initiative is highlighted in an editorial in the March issue of Lancet Neurology.

“There is a critical gap in the research that leads to lack of treatment for diseases like Parkinson’s,” said Scherzer. “Biomarkers are desperately needed to make clinical trials more efficient, less expensive and to monitor disease and treatment response. We are hopeful that this initiative will fast track new discoveries in this area.”

According to Scherzer, most of our knowledge of the human brain is based on the analysis of just 1.5 percent of the human genome that encodes proteins. The first part of Scherzer’s project will examine the function of the remaining 98.5 percent of the genome that, so far, has been unexplored in the human brain. While this remainder had been previously dismissed as “junk”, it is now becoming clearer that parts of it actively regulate cell biology. Scherzer and colleagues believe that “dark matter” RNA transcribed from stretches of so called “junk” DNA is active in brain cells and contributes to the complexity of normal dopamine neurons and, when corrupted, Parkinson’s disease.

“This offers a potentially ground breaking opportunity for biomarker development. Initially, the team will search for these RNAs associated in brain tissue of individuals at earliest stages of the disease. Then, this team will look for related biomarkers in the bloodstream and cerebrospinal fluid in both healthy brains and those with Parkinson’s,” Scherzer said.

Scherzer’s lab has been spearheading biomarker research in this field since 2004 and the team already has 2,000 patients enrolled and being followed in a longitudinal study with rich clinical data and one of the largest biobanks in the world for Parkinson’s tissue with support from the Harvard NeuroDiscovery Center. The biobank was designed as an incubator for Parkinson’s research and until now was chiefly available for research collaborations within the Harvard-affiliated community. As part of this new project, this vast resource will be open to all NIH-funded investigators.

“Our ultimate goal is to personalize treatment for our patients with Parkinson’s.” said Scherzer. “By opening up this vast collection of specimens, we are exploding the resources that are available to NIH-funded investigators looking at this disease. We hope to harness the power of collaboration to speed up biomarkers discovery.”

NIH Launches Collaborative Effort to find Biomarkers for Parkinson’s

A new initiative aims to accelerate the search for biomarkers — changes in the body that can be used to predict, diagnose or monitor a disease — in Parkinson’s disease, in part by improving collaboration among researchers and helping patients get involved in clinical studies.

NIH to Fund Studies on the Clinical Utility of Extracellular RNA for Biomarker Development

The National Institutes of Health announced last week that the National Institute of Neurological Disorders and Stroke (NINDS) on behalf of the NIH Common Fund Program on Extracellular RNA Communication will support studies that promote the identification and validation of extracellular RNA (exRNA)-based biomarkers readily available from human body fluids and to facilitate the assessment and qualification of biomarkers for their utility in the clinical setting.

NHI to Support Biomarker Discovery for Phase II Parkinson’s Disease Clinical Trials

Last month, the National Institutes of Health announced that the National Institute of Neurological Disorders and Stroke (NINDS) will support hypothesis driven clinical research to discover biomarkers that will improve the efficiency and outcome of Phase II clinical trials for Parkinson’s Disease (PD) and support the collection of clinical data and new biological specimens that will be used for biomarker exploratory efforts under the NINDS Parkinson’s Disease Biomarkers Program (PDBP).

International Research Team Discovers Genes and Disease Mechanisms Behind a Common Form of Muscular Dystrophy

Continuing a series of groundbreaking discoveries begun in 2010 about the genetic causes of the third most common form of inherited muscular dystrophy, an international team of researchers led by a scientist at Fred Hutchinson Cancer Research Center has identified the genes and proteins that damage muscle cells, as well as the mechanisms that can cause the disease. The findings are online and will be reported in the Jan. 17 print edition of the journal Developmental Cell.
