RNA molecules can orchestrate gene activity across vast portions of the human genome

Large, seemingly useless pieces of RNA - a molecule originally considered only a lowly messenger for DNA - play an important role in letting cells know where they are in the body and what they are supposed to become, researchers at Stanford University School of Medicine have discovered.

Call for change in regulations surrounding xenotransplantation

A new article in The Journal of Law, Medicine and Ethics calls for a change in the regulations surrounding xenotransplantation, the transplanting of animal cells, tissues or organs into humans.

Induction chemotherapy adds to survival rates in lung cancer patients

Patients with inoperable non-small cell lung cancer who receive an initial high dose of chemotherapy before their treatment begins can expect an increase in overall survival, according to a study in the July 1 issue of the International Journal of Radiation Oncology-Biology-Physics, the official journal of ASTRO.

Phosphatidylglycerol holds promise for psoriasis, age-related skin damage

The body may hold a secret to normalizing skin cell growth that is over zealous in psoriasis and non-melanoma skin cancers and too slow in aging and sun-damaged skin, researchers say.

Researchers increase in vivo lifetime of nanoparticles

Researchers at the University of California, Santa Barbara have discovered that attaching polymeric nanoparticles to the surface of red blood cells dramatically increases the in vivo lifetime of the nanoparticles.

New type of drug shows promise for chronic lymphocytic leukemia

A new type of engineered drug candidate has shown promise in treating chronic lymphocytic leukemia in both test tube and early animal tests, a new study shows.

Link between ciliary signaling and cancer

Submarines have periscopes. Insects have antennae. And increasingly, biologists are finding that most normal vertebrate cells have cilia, small hair-like structures that protrude like antennae into the surrounding environment to detect signals that control cell growth.

Injections of autologous myoblasts and fibroblasts could relieve stress urinary incontinence in women

Myoblasts are a type of muscle stem cell, while fibroblasts are cells which form the structural framework for many tissues in the body. Autologous cells are ones which the patient is the source of.

Protein ATM prevents DNA damage from persisting through generations

A protein long known to be involved in protecting a cell from genetic damage has been found to play an even more important role in protecting the cell's offspring.

Key finding on ALS related protein

Chemists from UCLA and the University of Florence in Italy may have solved an important mystery about a protein that plays a key role in a particular form of amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, a progressive, fatal neurodegenerative disorder that strikes without warning.

Support for chromosomal theory of cancer found in cancers' development of drug resistance

Thirty-six years into the war on cancer, scientists have not only failed to come up with a cure, but most of the newer drugs suffer from the same problems as those available in the pre-war days: serious toxicity, limited effectiveness and eventual resistance.

New type of mouse embryonic stem cell discovered

Scientists have discovered a new type of mouse embryonic stem cell that is the closest counterpart yet to human embryonic stem (ES) cells, the National Institutes of Health (NIH) have announced.

Scientists discover role of ataxia telangiectasia mutated protein in DNA repair

Scientists from the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), National Cancer Institute (NCI), and Integrative Bioinformatics Inc. have made an important discovery about the role of an enzyme called ataxia telangiectasia mutated protein (ATM) in the body's ability to repair damaged DNA.

New model for signal transduction in cells

Among the key communication systems within a cell is the Wnt signaling pathway, which regulates embryonic development and whose deregulation can also contribute to cancer development.

New genetic test advances detection and diagnosis of muscular dystrophy

A new genetic test targeting the most common types of muscular dystrophy--those caused by mutations in the dystrophin gene--is far quicker with greater accuracy and sensitivity than existing tests.

Bayer and Onyx submit supplemental NDA for Nexavar

Bayer HealthCare Pharmaceuticals and Onyx Pharmaceuticals have announced that a Supplemental New Drug Application (sNDA) for Nexavar (sorafenib) tablets has been submitted to the U.S. Food and Drug Administration (FDA) for the treatment of patients with hepatocellular carcinoma (HCC), the most common form of liver cancer. Nexavar is currently approved in more than 50 countries for the treatment of advanced kidney cancer.
