Genetic ancestry of African-Americans reveals new insights about gene expression

The amount of proteins produced in cells—a fundamental determinant of biological outcomes collectively known as gene expression—varies in African American individuals depending on their proportion of African or European genetic ancestry.

Chromatin packaging helps decipher how cancer develops

To decipher how cancer develops, Johns Hopkins Kimmel Cancer Center investigators say researchers must take a closer look at the packaging.

Researchers focus on phosphoinositide 3-kinase pathway in cancer research

Researchers are taking a closer look at the phosphoinositide 3-kinase (PI3-kinase) pathway as studies continue to demonstrate that inhibiting this biological route suppresses tumor growth, reports Genetic Engineering & Biotechnology News (GEN ).

Discovery of MEDNIK syndrome

Canadian researchers announce the discovery of MEDNIK Syndrome, a debilitating genetic syndrome.

Stem cells derived from bone marrow may offer novel therapeutic option for epidermolysis bullosa

Stem cells derived from bone marrow may serve as a novel therapeutic option to treat a disease called epidermolysis bullosa (EB), a disorder characterized by extraordinarily fragile skin, according to a study prepublished online in Blood, the official journal of the American Society of Hematology.

A new approach improves prioritization of disease-associated SNPs

The more often a gene is differentially expressed, the more likely it is to contain disease-associated DNA variants.

Discovery of new enzyme in cancer growth

While studying the mechanics of blood clots, researchers at the University of Oklahoma Health Sciences Center discovered a new enzyme that not only affects the blood, but seems to play a primary role in how cancer tumors expand and spread throughout the body.

Tobacco plants grown in novel mist bioreactor system provide new soure of interleukin-12

Interleukin-12 is a naturally occurring protein essential for the proper functioning of the human immune system.

Motor neurons derived from human embryonic stem cells provide insight into ALS

Two new research studies use motor neurons derived from human embryonic stem (hES) cells to demonstrate that multiple toxic pathways contribute to the devastating degeneration associated with Amyotrophic Lateral Sclerosis (ALS) and that protective therapeutics will need to oppose the disease on multiple fronts.

Genetic breakdown in Fanconi anemia may have link to HPV-associated cancer

A genetic malfunction that causes DNA instability in people with the blood disorder Fanconi anemia may put them at high risk for squamous cell carcinomas linked to human papillomavirus (HPV), according to a study posted online ahead of print by Oncogene.

Gene therapy used to alleviate sickle cell disease pathology

Using a harmless virus to insert a corrective gene into mouse blood cells, scientists at St. Jude Children's Research Hospital have alleviated sickle cell disease pathology.

Discovery of gene variants that impact the placebo effect

It is a well-known fact in drug trials that individuals can respond just as well to placebos, sugar pills, as to the active drug.

New insights into cellular senescence

Scientists have identified a molecular cause behind the ravages of old age and in doing so have also shown how a natural process for fighting cancer in younger persons can actually promote cancer in older individuals.

Researchers develop human embryonic stem cell-based system for modeling ALS

Long thought of as mere bystanders, astrocytes are crucial for the survival and well-being of motor neurons, which control voluntary muscle movements.

New evidence shows that the heart beats to its own drummer

They've uncovered some of the molecular circuitry within the cardiovascular system itself that controls the daily rise and fall of blood pressure and heart rate. The findings might also explain why commonly used diabetes drugs come with cardiovascular benefits, according to the researchers.

Young researcher identifies binocular vision gene

Dr Catherine Leamey from the School of Medical Sciences at the University of Sydney has been awarded the 2008 Sir Zelman Cowen Universities Fund Prize for Medical Research for her work in identifying the gene that enables binocular vision.

Discovery of a presbycusis related gene

Presbycusis, or age-related hearing loss, accounts for 30 percent of all hearing loss. So, why do some people lose their hearing as they get older but other people can still hear a pin drop?

New technique provides closer look at DNA and mRNA

In a study in the advance online edition of Nature Structural and Molecular Biology, researchers from Albert Einstein College of Medicine describe a technique for looking more precisely at a fundamental step of a cell's life - a gene, DNA, being read into a message, mRNA.
