“Microbial dark matter" undoubtedly contains key information about how our microbiome contributes to human health and disease. But how do you study something you can’t see?
Effective interpretation and identification of causative and actionable mutations in disease states is still a major hurdle to the delivery of personalized genomics.
Assistant Professor Zhengqing Ouyang, Ph.D., received a one-year, $100,000 Research Starter Grant in Informatics from the Pharmaceutical Research and Manufacturers of America (PhRMA) Foundation.
In an article published the week in the journal Human Molecular Genetics, Gayle Collin, working in the laboratory of Patsy Nishina at the Jackson Laboratory in Bar Harbor, describes a new murine model of the human vision disorders.
Most cases of amyotrophic lateral sclerosis (ALS) are sporadic, meaning that there is no family history of the disease.
The National Institute of Biomedical Imaging and Bioengineering, an institute of the National Institutes of Health (NIH), awarded Associate Professor Jeffrey Chuang was awarded a three-year, $390,000 grant for “Big Genomic Data Skills Training for Professors.”
In an article published in Nature Genetics in November, Candice Baker and Stephen Murray of JAX Bar Harbor were members of a team investigating genes that may be responsible for heterotaxy in humans.
New multi-institutional group of leading microbiome researchers seeks to deepen our knowledge of the microbiome and apply lessons from this emergent area of research.
Charcot-Marie-Tooth (CMT) diseases are the most common family of inherited diseases called peripheral neuropathies. The junctions between muscles and nerves and the nerves themselves that carry signals between brain and muscles degenerate over time, leading to impaired movement, including balance problems and difficulty walking. CMT diseases have a range of severity but are rarely life-threatening.
As we age, it becomes more difficult to maintain good health, and we become more susceptible to diseases such as cancer, heart disease and stroke with each passing year. That fact seems so basic that it’s surprising that no one really understands the basic mechanisms underlying aging and why the aging process has such a large impact on wellbeing. And as researchers delve deeper into the subject, answers remain elusive.
Retroviruses are known to spread between cells in vitro, but mechanisms for spread in vivo are not well understood. Knowledge of how the spread occurs is important for improving HIV prevention and therapies.
Assistant Professor Gareth Howell, Ph.D., received a two-year grant from the National Institute of Neurological Disorders and Stroke (NINDS) to more accurately model the role of the human complement cascade for disease research.
The single-cell technology, methods and expertise Paul Robson brings to JAX have the potential to advance many of the ongoing research programs.
New research from the University of California Davis and The Jackson Laboratory provides more evidence that patient-derived xenografts (PDXs), human tissues implanted in immunocompromised mice, can provide powerful insight into cancer mechanisms and therapies.
Professor Karolina Palucka, M.D., received an RO1 grant award for “Humanized mouse models to dissect in vivo the interplay between melanoma and the immune system."
Mice that receive sporadic, high-level doses of antibiotics—emulating typical prescriptions for children—experience significant changes in body composition and microbiome.
CHDI Foundation, The Jackson Laboratory, and PsychoGenics, Inc. have developed a new field guide for researchers studying Huntington's disease.
Working with research partners, the Jackson Laboratory genetically engineers new mouse models, from construct creation and microinjection to evaluation and characterization.
The term epilepsy refers to a spectrum of brain disorders resulting from a disturbance of the normal pattern of neuron activity.
