Tumour suppressor gene family may be key to new colon cancer drugs

In the hunt for new cancer drug targets, scientists from the Johns Hopkins Kimmel Cancer Center and the Howard Hughes Medical Institute have discovered mutations in a family of genes linked to more than a quarter of colon cancers, as well as several other common cancers including breast and lung.

A genetic variant (MTHFR C677T) puts half the population at increased risk of neural tube defects

Researchers in Ireland and the United States identified the genetic make-up (genotype) of 395 individuals born with neural tube defects (spina bifida or encephalocele) and 848 controls.

Scientists have taken the first steps towards producing a sustainable and pure source of the healthy fats found in oily fish

Eating such fish is encouraged as part of a healthy diet as their oils are rich in very long chain polyunsaturated fatty acids (VLCPUFAs). However, views on the health-promoting nature of VLCPUFAs have to be balanced against the marine pollution that can cause fish, and the oils extracted from them, to be contaminated with heavy metals and dioxins, and the fact that fish stocks are in global decline.

Causes of hepatitis and potential therapies that may improve care presented in study

Hepatitis, a potentially serious disease caused by a virus that attacks the liver, is a major problem worldwide. Hepatitis A is generally food-borne, while hepatitis B and C spread primarily through parenteral or sexual routes. Hepatitis B and C can be life-long, potentially deadly chronic infections.

Enteric-coated aspirin is less potent than plain aspirin

Enteric-coated aspirin is less potent than plain aspirin, which may make it less effective in preventing heart disease, according to a preliminary small study presented today at the American Heart Association’s 5th Annual Conference on Arteriosclerosis, Thrombosis and Vascular Biology.

Inactivating a protective molecule may help chemotherapy for leukemia but harm bone marrow

Inactivating a protective molecule in leukemic cells to make them more vulnerable to chemotherapy might also make healthy blood-forming cells more sensitive to the toxic effects of those same drugs.

Researcher has learned how to maximize the cancer-fighting power of broccoli

University of Illinois researcher Elizabeth Jeffery has learned how to maximize the cancer-fighting power of broccoli. It involves heating broccoli just enough to eliminate a sulfur-grabbing protein, but not enough to stop the plant from releasing an important cancer-fighting compound called sulforaphane.

Glucose metabolism could be used to selectively destroy cancer cells

Scientists have known for decades that cancer cells consume more glucose than normal cells. A longstanding assumption that the excess glucose metabolism was needed to make energy has not been borne out by research studies.

Vitamin discovery offers clues for cancer chemotherapy

NH-Dartmouth Medical School cancer researchers, in a fusion of biochemistry and genetics, have discovered a new vitamin in a molecular pathway central to such vital processes as gene regulation, metabolism and aging. And, they found that milk contains this nutrient.

New chink in the cellular armor of tuberculosis (TB) and leprosy

The family of bacteria that causes tuberculosis (TB) and leprosy are notoriously sturdy. And although the diseases they cause have been held in check for the past 50 years by antibiotics, some strains are becoming increasingly resistant to existing therapy.
