Infertility, heart disease, osteoporosis and genetic mutations

Mutations in a gene called FIGLA cause premature ovarian failure in at least 1% of women who suffer from the disorder, said researchers from Baylor College of Medicine in Houston and Shandong University in China in a report that appears online in the American Journal of Human Genetics. Premature ovarian failure, which means that the ovaries […]

Heart cells grown from stem cells

Cardiomyocytes 
Stem cells have been used to create heart cells under lab conditions by researchers from the McEwen Centre for Regenerative Medicine in Toronto.
By supplying the right growth factors at the right time, they encouraged the cells to grow into immature versions of three different types of cardiac cell.
The three cell types they created - cardiomyocytes, […]

Genetic basis for painful peripheral artery disease

Peripheral artery disease image showing ‘furring up’ of arteries 
Peripheral vascular disease (PVD) can affect the arteries, the veins or the lymph vessels. The most common and important type of PVD is peripheral artery disease, which affects about 8 million Americans.  It becomes more common as a person gets older, and by age 65, about 12 to 20 % of […]

Snoring linked to heart disease

 (Courtesy Daniel P Urban DDS) 
More than 12,000 people were interviewed in their homes and questioned about snoring.
It is estimated that about 40% of adult males and 24% of adult females are habitual snorers.  For several years now, scientists have been aware of a relationship between snoring and cardiovascular disease.  However a team of Hungarian scientists interviewed […]

Genetic adaptations to surviving a cold climate linked to diabetes, obesity and heart disease

 
Our early human ancestors originated from a hot, humid climate where natural selection focused on dispersing heat.  As humans migrated to colder climates there would have been evolutionary pressure to adapt to their new settings by boosting the processes that produce and retain heat.
Genes involved in energy metabolism are therefore likely to be central to heat and cold […]

Genetically Engineered Pigs Make Omega-3 Fatty Acids

Pork containing omega-3 fatty acids, which may reduce the risk of heart disease, could be available in the future. Researchers at Harvard University are also working on cows that make omega-3’s in their milk and chickens that have the fatty acids in their eggs.

PCSK9 Gene and Heart Disease

Low density lipoprotein (LDL) cholesterol is the main culprit in causing clogged arteries and atherosclerosis. About half of the variation in LDL cholesterol in the blood is due to genetics. Thus far, eight different genes have been identified with the PCSK9 gene having three forms that are associated with lower plasma LDL levels.

Two […]
