The genes are composed of DNA and are carried on the chromosomes. Genes direct the production of all the molecules that form the structures that of a cell. Genes determine the inherited characteristics that distinguish one individual from another. Each human has an estimated 90,000 genes.
Yale researchers discover many genetic keys needed to unlock autism – Investigating 1,000 families reveals hundreds of small genetic variations are associated with autism spectrum disorders, according to a multi-site collaborative study led by researchers at Yale University. These genetic findings can be used to begin unraveling the underlying biology of autism.
New strain of MRSA discovered — Antibiotic resistant bacteria found in both humans and dairy cows – Scientists have identified a new strain of methicillin-resistant Staphylococcus aureus (MRSA) which occurs both in human and dairy cow populations. The study, led by Dr Mark Holmes at the University of Cambridge, identified the new strain in milk from dairy cows while researching mastitis (a bacterial infection which occurs in the cows’ udders).
Low vitamin D levels seen as multiple sclerosis risk for African-Americans, UCSF study finds – Vitamin D levels in the blood are lower in African Americans who have the disease, compared to African Americans who do not, revealed by researchers exploring the connection between vitamin D and multiple sclerosis in African Americans.
Autism changes molecular structure of the brain, UCLA study finds — Discovery points to a common cause for multifaceted disease – A new UCLA study is the first to reveal how the autism disorder makes its mark at the molecular level, resulting in an autistic brain that differs dramatically in structure from a healthy one.
‘Master switch’ gene for obesity and diabetes discovered — Researchers have found that a gene linked to type 2 diabetes and cholesterol levels is in fact a ‘master regulator’ gene, which controls the behavior of other genes found within fat in the body – A team of researchers, led by King’s College London and the University of Oxford, have found that a gene linked to type 2 diabetes and cholesterol levels is in fact a ‘master regulator’ gene, which controls the behaviour of other genes found within fat in the body.
Gene expression changes in nasal cells may help identify lung cancer in earliest stages – A simple, minimally-invasive technique using cells from the interior of the nose could help clinicians detect lung cancer in its earliest – and most treatable – stages, according to a study conducted by researchers in Boston.
Cancer scientists discover new way breast cancer cells adapt to environmental stress – An international research team led by Dr. Tak Mak, Director, The Campbell Family Institute for Breast Cancer Research at Princess Margaret Hospital (PMH), has discovered a new aspect of “metabolic transformation”, the process whereby tumour cells adapt and survive under conditions that would kill normal cells.
What decides neural stem cell fate? — A gene called SOX2 acts as a stem cell gatekeeper — only cells expressing it have the potential to become neurons – Early in embryonic development, the neural crest ? a transient group of stem cells ? gives rise to parts of the nervous system and several other tissues. But little is known about what determines which cells become neurons and which become other cell types.
Activation of Biomarker Appears Associated With Improved Survival Among Obese Patients With Colorectal Cancer – Among obese patients, activation of the protein biomarker CTNNB1 was associated with better colorectal cancer-specific survival and overall survival, whereas post-diagnosis physical activity was associated with better colorectal cancer-specific survival among patients negative for CTNNB1.
Protein levels could signal that a child will develop diabetes – Decreasing blood levels of a protein that helps control inflammation may be a red flag that could help children avoid type 1 diabetes, researchers say.
Low carbohydrate diet may reverse kidney failure in people with diabetes – Researchers from Mount Sinai School of Medicine have for the first time determined that the ketogenic diet, a specialized high-fat, low carbohydrate diet, may reverse impaired kidney function in people with Type 1 and Type 2 diabetes.
Researchers identify genes causing antimalarial drug resistance – Using a pair of powerful genome-search techniques, researchers from the Harvard School of Public Health (HSPH), Harvard University, and the Broad Institute have identified several genes that may be implicated in the malaria parasite’s notorious ability to rapidly evade drug treatments.
