Neuherberg, December 9, 2010. Starting in August 2010, The Michael J. Fox Foundation for Parkinson’s Research will fund a project at Helmholtz Zentrum München aimed at determining the structure of the protein LRRK2. The protein is central to the development of Parkinson’s Disease (PD) and is considered to be an important target for effective therapies for the neurodegenerative disease.

Starting in August 2010, an innovative project will be funded at Helmholtz Zentrum München which could pave the way for an effective therapy for PD. The aim of the project is to obtain a crystal structure of the kinase domain of the LRRK2 protein and describe its biochemical and enzymatic functions. Professor Michael Sattler, director of the Institute of Structural Biology, Professor Marius Ueffing, head of the Department of Protein Science and Dr. Johannes Gloeckner led by Dr. Alex Burgin at Emerald Biostructures want to develop new methods in order to be able to purify and biochemically characterize larger quantities of the protein or its relevant domains. Biochemical methods shall be combined with NMR spectroscopy, small-angle X-ray scattering experiments, and ultimately X-ray crystal structure analysis in order to decode the spatial structure of the protein. “Solving the structure of the enzyme believed to be a key molecular mechanism behind Parkinson’s disease could revolutionize the field,” said Dr. Burgin, Emerald BioStructures.

LRRK2 (leucine-rich repeat kinase 2) is considered to be the central factor in the development of a genetic form of PD. The hyperactivity of the enzyme could lead to increased loss of neurons in the midbrain, which is characteristic of this common neurodegenerative disease. “When the structure of LRRK2 is known, we will have legitimate hope for developing new therapeutic approaches, at least for LRRK2-associated PD,” said Professor Sattler. Knowledge of the protein structure is a prerequisite for rationally developing and optimizing active substances against Parkinson’s. “At the same time,” he added, “we will gain new insights into how Parkinson’s develops, enabling an intervention at earlier stages in the future.”


Background:

Parkinson’s Disease is a slowly progressing neurodegenerative disease in which dopaminergic nerve cells in midbrain die. This leads to muscular rigidity (rigor), slowness of movement (bradykinesia), muscle tremors and postural instability, apart from other disturbances. Besides the classic sporadic form (idiopathic Parkinson‘s syndrome), familial, genetically determined forms are also known. Type 8 is the most frequent familial form of Parkinson’s Disease and is caused by mutations in the LRRK2 gene.

The LRRK2 protein consists of multiple domains and belongs to the family of protein kinases. Kinases transfer phosphate groups to target proteins and thus contribute to the control of cellular processes. The mutations of LRRK2 associated with Parkinson’s Disease presumably lead to enhanced kinase activity.

About The Michael J. Fox Foundation MJFF is dedicated to finding a cure for Parkinson's disease through an aggressively funded research agenda and to ensuring the development of improved therapies for those living with Parkinson's today. The Foundation has funded nearly $214 million in research to date. For more information, please visit www.michaeljfox.org.

Drug discovery and testing, with their need for speed, repeatability and verification, are ideally suited to benefit from robot automation. It is therefore not surprising that robots have been at the forefront of automation developments in both these areas.

HP Scalable Network Storage Systems for Life Sciences

Sep 13

Life sciences research today is advancing exponentially, each step bringing us closer to the realization of truly personalized medicine–preventive care and treatments designed specifically for each individual. In the near future, PCPGM healthcare researchers expect to be able to use predictive genetic testing to create custom treatment plans for individuals and deliver dramatic improvements over today’s one-size-fits-all approach. But research capabilities are only part of the equation; current storage and operating capacities must also evolve to accommodate ever-expanding amounts of data before the goal of personalized medicine can be realized.

Step up to the MIQE

Mar 30

Over the years, polymerase chain reaction (PCR) has evolved into a readily automated, high throughput quantitative technology. Real-time quantitative PCR (qPCR) has become the industry standard for the detection and quantification of nucleic acids for multiple application, including quantification of RNA levels. But a lack of consensus among researchers on how to best perform and interpret qPCR experiments presents a major hurdle for advancement of the technology. This problem is exacerbated by insufficient experimental detail in published work, which impedes the ability of others to accurately evaluate or replicate reported results.

Ensuring Quality in Assays Performed with Automated Liquid Handlers

Feb 2

The focus of this presentation is to highlight the need of ensuring quality in important assays performed with automated liquid handlers. Nearly all assays performed within a laboratory are volume-dependent. In turn, all concentrations of biological and chemical components in these assays, as well as the associated dilution protocols, are volume-dependent. Because analyte concentration is volume-dependent, an assay’s results might be falsely interpreted if liquid handler variability and inaccuracies are unknown or if the system(s) go unchecked for a long period.

X-ray crystallography is used routinely by scientists to obtain the three dimensional structure of a biological molecule of interest.Such information can be used to determine how a pharmaceutical interacts with a protein target and what changes might improve functionality. However, the crystallization of macromolecules still remains a serious hindrance in structural determination despite impressive advances in screening methods and technologies.

Attention Deficit & Hyperactivity in a Drosophila Memory Mutant

Attention Deficit & Hyperactivity in a Drosophila Memory Mutant

Nov 9 2009

Action selection is modulated by external stimuli either directly or via memory retrieval. In a constantly changing environment, animals have evolved attention-like processes to effectively filter the incoming sensory stream. These attention-like processes, in turn, are modulated by memory. The neurobiological nature of how attention, action selection and memory are inter-connected is unknown. We describe here new phenotypes of the memory mutant radish in the fruit fly Drosophila.
