Getting Long in the Telomeres

Robin Smith, Health Content Scientist Barring injury, disease or capture, some scientists believe that a lobster could live virtually forever. They are amongst a select group of animals, including tortoises, clams and jellyfish, that are "negligibly senescent." They don't age much. So why aren't we ...

SNPwatch: Four More DNA Variations Linked to Testicular Cancer

British researchers have identified four new genetic variants that may influence a male's risk for testicular cancer.  These results, published recently in the journal Nature Genetics, along with variations in three genetic regions previously identified by the same group, are beginning to shed some light on ...

SNPwatch: New Genetic Associations Revealed for Nasopharyngeal Carcinoma

Nasopharyngeal cancer (NPC) arises in the upper part of the throat, behind the nose.  It is rare in most areas of the world—affecting only about 1 in every 100,000 people—but about 25 times more common in southern China, earning it the name "Cantonese Cancer."  NPC rates are also high in southeastern Asia, ...

SNPwatch: Genetic Variant Associated with Food Allergy-related Disorder Eosinophilic Esophagitis

For the millions of children and adults with severe food allergies, ingesting even tiny quantities of some of the most basic foods can result in a potentially deadly reaction.  Milk, eggs, nuts, fish, shellfish, soy and wheat are some of the most common offenders. Some people with food sensitivities have ...

SNPwatch: Researchers Identify Variation Associated with Biological Aging

The candles on your birthday cake tell you how many years you've lived through, but they might not be a reflection of your biological age. Little bits of DNA called telomeres protect the ends of chromosomes.  Over time, through repeated rounds of cell division, telomeres get shorter and shorter.  Thus, ...

SNPwatch: More Common Genetic Variants Associated with Risk of Pancreatic Cancer

Cancer of the pancreas, which strikes more than 40,000 men and women in the United States each year, is an especially deadly malignancy.   There is no effective screening test for the disease and it is usually not detected until it has spread throughout the body.  The five-year survival rate is only about ...

SNPwatch: Two More Genetic Variants Linked to Cleft Lip and Palate

A new study has identified more common genetic variants associated with increased risk for cleft lip and palate.  Combined with two previous studies (more here and here), there are now four variations that have been associated with this birth defect that affects about one out of every 700 children ...

SNPwatch: Three New Genetic Variants Associated With Rheumatoid Arthritis Risk

The most common type of arthritis, osteoarthritis, occurs due to accumulated wear and tear – welcome to old age! – or from repetitive movements or injury.  Rheumatoid arthritis, on the other hand, is caused by an autoimmune attack on the lining of the joints, resulting in stiffness, muscle aches, and general ...
