New Genetic Findings On Depression

In a new study, scientists have found genetic markers associated with depression in people of European descent. In what is by far the largest study of its kind focused on major depressive disorder, researchers from Pfizer, Massachusetts General Hospital and 23andMe identified 17 single nucleotide ...

Genetics And Well Being

In one of the largest-ever genome wide association study for behavioral traits, researchers have found three genetic variants associated with a person’s sense of well-being. The study published this week in the journal Nature Genetics, also looked at genetic associations with depression and what is called ...

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: Taking Stock of Dengue Shock

We all know that mosquitoes can be annoying. In many parts of the world, however, mosquitoes are more than just annoying--they are killers. Most people have heard of the mosquito-transmitted disease malaria, which has recently received much publicity through the work of The Bill & Melinda Gates Foundation ...

SNPwatch: Researchers Identify Genetic Variant That May Affect Liver Cancer Risk in Those Chronically Infected with Hepatitis B Virus

Hepatocellular Carcinoma (HCC) is the fourth most common cancer in the world.  More than half a million new cases of this form of liver cancer are reported each year.  Excessive alcohol consumption and obesity have long been linked to HCC, but the main cause of the disease is chronic hepatitis B virus (HBV) ...

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 ...
