Researchers discover enzyme that is a natural tumor suppressor

Building on their 2005 discovery of an enzyme that is a natural tumor suppressor, researchers at the University of California, San Diego (UCSD) School of Medicine have now identified two variants of that enzyme which could provide new targets for therapies to treat diabetes, heart and neurological disease.

Immunological catch-22 with chronic infections

After a viral infection, a small percentage of the T cells generated to kill virus-infected cells remain on guard to establish long-term immunity.

Critical receptor in liver regeneration identified

In studies in mouse models, researchers at the University of California, San Diego (UCSD) School of Medicine have found that a cellular receptor involved in triggering cell death is also a necessary component of tissue repair and regeneration immediately following liver injury.

Preventing cancer without killing cells

Inducing senescence in aged cells may be sufficient to guard against spontaneous cancer development, according to a paper published online this week in EMBO reports.

New cardiovascular treatment approaches

In an era of increasing death and illness from heart and blood vessel disease - which also can impair kidney function - Mayo Clinic researchers have designed two promising new cardiovascular treatment approaches.

Scientists discover new approach for treating virus-induced lymphomas

Kaposi's sarcoma herpesvirus (KSHV) is a human tumor virus and an etiological agent for Kaposi's sarcoma and primary effusion lymphoma (PEL). PELs are aggressive lymphomas with reported median survival time shorter than six months after diagnosis.

New anti-cancer target in enzyme MAP4K3

Scientists working at the Institute for Cancer Research have found a new anti-cancer target in MAP4K3, an enzyme which is able to 'switch on' the growth-promoter mTOR.

Researchers discover a new mechanism that regulates stem cell division

Errors in stem cell division can give rise to tumours. By studying stem cells in the fruit fly, scientists at the Institute for Research in Biomedicine (IRB Barcelona) have identified one of the mechanisms that govern how these cells divide.

MIT researchers develop technique to encourage the survival and growth of adult stem cells

Adult stem cells, found in many tissues in the body, are precursor cells for specific cell types. For example, stem cells found in the bone marrow develop into blood cells, bone cells and other connective tissues, and neural stem cells develop into brain tissue.

Vitamin D deficiency widespread among women during pregnancy

Even regular use of prenatal multivitamin supplements is not adequate to prevent vitamin D insufficiency, University of Pittsburgh researchers report in the current issue of the Journal of Nutrition, the publication of the American Society for Nutrition.

Aspirin offers help for Barrett's esophagus

Researchers at Fred Hutchinson Cancer Research Center have found that people with the most-aggressive form of Barrett's esophagus, a precancerous condition that can lead to esophageal cancer, may benefit the most from preventive therapy with aspirin, ibuprofen and other nonsteroidal anti-inflammatory drugs, or NSAIDs.

Experts condemn the sexualisation of girls in the media

Experts in the United States are warning about the way young women are portrayed by the media.

Translationally controlled tumor protein key to organ growth

When amounts of a small protein called TCTP (translationally controlled tumor protein) are reduced in the cells of fruit flies, they are smaller than normal, indicating that the protein plays a major role in the growth and proliferation of cells, said researchers at Baylor College of Medicine in a report in current issue of the journal Nature.

Researchers discover markers that identify breast cancer subtypes resistant to Herceptin

Using gene chips to profile tumors before treatment, researchers at Harvard and Yale Universities found markers that identified breast cancer subtypes resistant to Herceptin, the primary treatment for HER2-positive breast cancer. They say this advance could help further refine therapy for the 25 to 30 percent of breast cancer patients with this class of tumor.

Psychologists call for replacing sexualized images of girls in media and advertising with positive ones

A report of the American Psychological Association (APA) released found evidence that the proliferation of sexualized images of girls and young women in advertising, merchandising, and media is harmful to girls' self-image and healthy development.

Countries should find balance between affordable drugs, development incentives, WHO Director-General says in letter to Thai Health Minister

World Health Organization Director-General Margaret Chan in a letter to Thai Health Minister Mongkol na Songkhla said that although the Thai government was fully within its rights to issue a compulsory license for Abbott Laboratories antiretroviral drug Kaletra, countries should find the "right balance" between providing affordable medicines and incentives for drug companies to develop new treatments.

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.

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.

Serious proliferation of multiresistant Staphylococcus in intensive care units

Multiresistant bacteria are a severe problem that costs lives at hospitals the world over. A new doctoral thesis from Karolinska Institutet in Sweden shows that the spread of disease between seriously ill patients in intensive care units is surprisingly rife.
