Epigenetics to shape stem cell future

Everyone hopes that one day stem cell-based regenerative medicine will help repair diseased tissue. Before then, it may be necessary to decipher the epigenetic signals that give stem cells their unique ability to self-renew and transform them into different cell types.

Global partnership to launch $10 million initiative that aims to bolster HIV/AIDS care in 10 African countries using cell phones

A new public-private partnership on Tuesday at the 2007 3GSM World Congress in Barcelona, Spain, announced the launch of a new $10 million campaign that will use cell phones to bolster HIV/AIDS care and treatment in 10 African countries, Reuters reports.

Kaiser Permanente launches long term project to collect genetic data

California-based HMO Kaiser Permanente on Wednesday announced the creation of a decades-long research project that will collect and analyze genetic information from hundreds of thousands of adult members, the San Jose Mercury News reports.

Genetic variations contribute to a person's risk for nicotine dependence

Americans are bombarded with antismoking messages, yet at least 65 million of us continue to light up. Genetic factors play an important role in this continuing addiction to cigarettes, suggest scientists at Washington University School of Medicine in St. Louis.

Researchers determine a critical factor in workings of proteins

Scientists know that a better understanding of how proteins bond could lead to more effective treatments for genetic disorders and other life-threatening conditions.

Enzyme important in fetal heart-cell failure - findings provide new targets for treatment

In almost all forms of heart failure, the heart begins to express genes that are normally only expressed in the fetal heart. Researchers have known for years that this fetal-gene reactivation happens, yet not what regulates it.

New targets in cancer mutation puzzle

University of Rochester scientists, while investigating the two most frequent types of mutations in cancer, discovered a possible new route to treatment that would take advantage of the mutations instead of trying to repair them.

Researchers replace organ in mice using 'single-parent' stem cells

Researchers at the University of Pennsylvania School of Veterinary Medicine have derived uniparental embryonic stem cells - created from a single donor's eggs or two sperm - and, for the first time, successfully used them to repopulate a damaged organ with healthy cells in adult mice.

Watercress shows anti-cancer potential

Eating watercress daily can significantly reduce DNA damage to blood cells, which is considered to be an important trigger in the development of cancer, University of Ulster scientists revealed.

HIV protein TAT used to pull protein Bim into cancer cells - helps kill cancer cells

Cancer cells are sick, but they keep growing because they don't react to internal signals urging them to die. Now researchers at Washington University School of Medicine in St. Louis have found an efficient way to get a messenger into cancer cells that forces them to respond to death signals. And they did it using one of the most sinister pathogens around - HIV.

Study shows PanK2 enzyme within mitochondria is triggered by the first step in fatty acid breakdown

Just as homes have smoke detectors, cells have an enzyme that responds to a buildup of fatty acids by triggering the production of a key molecule in the biochemical pathway that breaks them down, according to investigators at St. Jude Children's Research Hospital. This provides the cell energy while reducing the chance that excess fatty acids will accumulate.

Primary targets of HIV-1 infection in human vagina identified

The primary targets of HIV-1 infection in the human vagina have been definitively identified in a new study published in the February 2007 issue of the journal Immunity. The findings are likely to guide development of new strategies that will prevent HIV-1 transmission.

Shortening chromosomes cause for earlier cancer onset in families with Li-Fraumeni syndrome

In families with a high incidence of Li-Fraumeni syndrome, the ends of individuals' chromosomes act somewhat like a lit fuse, according to researchers at The Hospital for Sick Children in Toronto. Their findings detail how telomeres, the ends of the chromosomes, shorten with every successive generation, leading to more severe cancers at an earlier age.

Mechanism driving iron overload in thalassemia identified

Led by researchers at Weill Cornell Medical College in New York City, an international group of scientists has pinpointed a specific genetic relationship as the cause of dangerous iron overload in persons with a form of the inherited blood disease, beta-thalassemia.

New patented technology for next generation of DNA and RNA microarrays

A novel invention developed by a scientist from New York Institute of Technology (NYIT) could revolutionize biological and clinical research and may lead to treatments for cancer, AIDS, Alzheimer's, diabetes, and genetic and infectious diseases.

Biochip allows genes to express themselves

Biochip platforms that work as artificial cells are attractive for medical diagnostics, interrogation of biological processes, and for the production of important biomolecules.

Variation in gene caspase-8 may help protect against breast cancer

A large-scale analysis of data on breast cancer risk has concluded that a common variation in the gene caspase-8 (CASP8) is associated with a somewhat lower risk of the disease. Variants are small changes that occur in a gene sequence.

Women who donate eggs for stem cell research face few health risks

Women who donate their eggs for stem cell research or in vitro fertilization are not at increased risk of health complications, and most of the risks are a result of the hormones used to stimulate their bodies to release more than one egg, according to a report commissioned by the California Institute of Regenerative Medicine and released by the Institute of Medicine, Bloomberg reports.

Researchers discover how to fight iron disorders with a drug against hypertension

We all know that iron deficiencies are dangerous, but also too much iron is bad for our health. Our body stores excess iron in various tissues, where it can lead to organ failure and even death if not treated before irreversible damage has occurred.

Indicators for risk of heart disease are higher in passive smokers

Exposure to second-hand smoke at work, home or elsewhere results in a disproportionate rise in markers that increase the risk of cardiovascular disease, University of Nottingham researchers have found.
