SNPwatch: Genetic Clues to Bowel Disease Found in Mice and Men

Inflammatory bowel disease (IBD), which can appear as either ulcerative colitis or Crohn's disease, damages the lining of the digestive tract and leads to abdominal cramps, incomplete digestion and nutritional deficiencies. Previous research on IBD gave researchers reason to suspect that the CD39 gene, ...

SNPwatch: Evidence for Gene-Environment Interaction in Alcoholism

Addiction to alcohol is associated with the brain’s reward system, which reinforces behaviors that feel good — like drinking — by releasing neurotransmitters such as dopamine and endorphins. With prolonged alcohol consumption, a person's brain can gradually adapt to the point that excessive amounts of ...

SNPwatch: Genetic Flaw that Causes Rare Metabolic Condition May Also Increase Risk of Severe Liver Disease in Cystic Fibrosis

New research suggests the primary genetic mutation that causes alpha-1 antritrypsin deficiency, a condition that results in liver damage and a wide variety of other problems, also affects risk for liver disorders associated with cystic fibrosis. Cystic fibrosis is an inherited, childhood-onset disorder ...

SNPwatch: Genetic Variations May Increase Risk Of Prostate Cancer In Japanese Men

This MRI of a man's pelvis shows that his prostate is enlarged to almost three times the regular size, which may be a sign of cancer. The prostate is marked by a cross. Prostate cancer, the most common cancer to affect men, kills 30,000 men of all ethnicities each year. The disease is known to have a ...

SNPwatch: Genetic Variations May Increase Risk for ALS

Scientists are narrowing in on two regions of the human genome that could be responsible for ALS (amyotrophic lateral sclerosis), also known as Lou Gehrig's disease. ALS is a neurodegenerative disorder that weakens muscles and paralyzes patients within three years of onset, and has no known cure. The ...

What Makes Us Human? Study Finds Hints By Comparing Chimp and Human DNA

We may be another step closer to discovering what makes us human. A new study published online this week in Genome Research has pinpointed three genes in humans that may genetically differentiate us from chimps and other primates. Genetically we are very similar to chimps, so most of the differences ...

Study Sniffs Out Genes Behind Doggy ‘Dos

New genetic research may explain why Fluffy is so fluffy. A study led by researchers at the National Human Genome Research Institute scanned 1,000 dogs from 80 breeds, looking for genes associated with different hair types: curly, wavy, straight, wiry, long and any combination of these. Their results, ...

Very Personalized Medicine: Sequencing of Second Cancer Patient Reveals Potentially Significant Mutations

A new genetic screening process has helped researchers understand the genetic causes of cancer, such as how mutations accumulated in a person's life can cause leukemia. The study shows that by comparing a person's own DNA to that of their cancerous cells, researchers can find DNA mutations that may have ...

Whence Rover? Genetic Study Suggests Africa May Have Whelped Man’s Best Friend

The Rexes and Spots of the world have been man's best friend for 15,000 years. But when and where did humans begin domesticating these furry companions? Previous theories suggested that the domesticated dog originated in East Asia and then spread to Africa, Oceania and the Americas. But a recent study by ...
