Autism Susceptibility Genes Identified

Two genes have been associated with autistic spectrum disorders (ASD) in a new study of 661 families. Researchers writing in BioMed Central’s newly launched journal Molecular Autism found that variations in the genes for two brain proteins, LRRN3 and LRRTM3, were significantly associated with susceptibility to ASD. Check the end of this report for a […]

One Gene Lost Equals One Limb Regained? Potential Implications For Human Limb Regeneration

A quest that began over a decade ago with a chance observation has reached a milestone: the identification of a gene that may regulate regeneration in mammals. The absence of this single gene, called p21, confers a healing potential in mice long thought to have been lost through evolution and reserved for creatures like flatworms, […]

Brain Plaques May Explain Higher Risk Of Alzheimer’s Disease Based On Mom’s History

A family history of Alzheimer’s is one of the biggest risk factors for developing the memory-robbing disease, which affects more than 5 million Americans and is the most common form of senile dementia. Now an international collaboration led by NYU Langone Medical Center researchers has found the likely basis for this heightened familial risk – […]

Autism Consortium Study In Pediatrics Shows CMA Finds More Genetic Abnormalities Than Current Tests

The Autism Consortium, an innovative research, clinical, and family collaboration dedicated to catalyzing research and enhancing clinical care for families with autism spectrum disorders (ASDs), announced today that the results of its comparison study of genetic testing methods for autism spectrum disorders is available from the journal Pediatrics through early online release in their eFirst […]

Studies On Nutrients And Gene Expression Could Lead To Tailored Diets For Disease Prevention

Personal health recommendations and diets tailored to better prevent diseases may be in our future, just by focusing on genetics. Researchers at Kansas State University recently published an academic journal article discussing the potential for nutrigenomics, a field that studies the effects of food on gene expression.

(click to enlarge) Canine retina two years post injection.  Retinal photograph taken more than two years after subretinal injection of AAV2-hRPE65v2 in the second eye of a dog model of Leber's congenital amaurosis due to RPE65 mutations. The AAV-exposed portion of the retina, with the overlying inner retinal blood vessels, appears yellow due to reflective changes in the underlying tapetum.

Second Dose Of Gene Therapy For Inherited Blindness Proves Safe In Animal Studies

Gene therapy for a severe inherited blindness, which produced dramatic improvements last year in 12 children and young adults who received the treatment in a clinical trial, has cleared another hurdle. The same research team that conducted the human trial now reports that a study in animals has shown that a second injection of genes […]

MIT Neuroscientists Develop Promising Treatments That Could Reverse Autism, Mental Retardation, And Alzheimer’s Disease

In his own words, MIT neuroscientist Mark Bear admits he did not “wake up one day and say, ‘Hey, I’m going to cure autism.’” But, after decades of painstaking basic research on how the brain rewires itself in response to external cues, Bear has discovered a way to reverse the symptoms of Fragile X Syndrome, […]
