Adolescent's weight, socioeconomic status may affect cancer later in life

Overweight adolescents were twice as likely as their normal weight peers to later develop esophageal cancer in a recent study from Israel. The study, which is published early online in CANCER, a peer-reviewed journal of the American Cancer Society, also found that lower socioeconomic status as well as immigration from higher risk countries were important determinants of gastric cancer.

Kidney failure can complicate long-term outcomes in children receiving solid-organ transplants

Children who undergo transplants of solid organs have a high risk of developing advanced kidney disease, according to a new national study. Among these children, the highest risk is in those receiving lung or intestinal transplants, followed by heart and then liver transplants. The researchers say their findings reinforce the importance of continued screening of kidney function in pediatric transplant recipients.

Football-shaped particles bolster the body's defense against cancer

Researchers at Johns Hopkins have succeeded in making flattened, football-shaped artificial particles that impersonate immune cells. These football-shaped particles seem to be better than the typical basketball-shaped particles at teaching immune cells to recognize and destroy cancer cells in mice.

Choreographed origami

An important step in building ribosomes – the cell's protein factories – is like a strictly choreographed dance, scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have discovered. To build these factories, other 'machines' inside the cell have to produce specific RNA molecules and fold them into the right shape, then combine the folded RNA with proteins to form a working ribosome. Like a budding origami artist pencilling in the folds, the cell uses tags called methyl groups to help mark where and how an RNA molecule should be folded.

Study shows that diet and lifestyle advice for those with diabetes should be 'no different' from that for general public

New research published in Diabetologia (the journal of the European Association for the Study of Diabetes [EASD]) suggests that lifestyle advice for people with diabetes should be no different from that for the general public, although those with diabetes may benefit more from that same advice. The research is by Dr Diewertje Sluik, Department of Epidemiology, German Institute of Human Nutrition Potsdam-Rehbruecke, Nuthetal, Germany, and colleagues.

In a surprise finding, gene mutation found linked to low-risk bladder cancer

WASHINGTON — An international research team led by scientists from Georgetown Lombardi Comprehensive Cancer Center has discovered a genetic mutation linked to low-risk bladder cancer. Their findings are reported online today in Nature Genetics.

Study identifies 4 genetic variants linked to esophageal cancer and Barrett's esophagus

SEATTLE – An international consortium co-led by researchers at Fred Hutchinson Cancer Research Center and the QIMR Berghofer Medical Research Institute in Australia has identified four genetic variants associated with an increased risk of esophageal cancer and its precursor, a condition called Barrett's esophagus.

Database of disease genes shows potential drug therapies

Researchers at Washington University School of Medicine in St. Louis have created a massive online database that matches thousands of genes linked to cancer and other diseases with drugs that target those genes. Some of the drugs are approved by the U.S. Food and Drug Administration, while others are in clinical trials or just entering the drug development pipeline.

The role of 'master regulators' in gene mutations and disease

Researchers at the University of California, San Diego School of Medicine have developed a new way to parse and understand how special proteins called "master regulators" read the genome, and consequently turn genes on and off.

McMaster researchers "fish new pond" for antibiotics

Hamilton, ON (Oct. 13, 2013) -- Researchers at McMaster University are addressing the crisis in drug resistance with a novel approach to find new antibiotics.

"We have developed technology to find new antibiotics using laboratory conditions that mimic those of infection in the human body," said Eric Brown, professor in the Department of Biochemistry and Biomedical Sciences.

Spanish researchers sequence non-infiltrating bladder cancer exome

Bladder cancer represents a serious public health problem in many countries, especially in Spain, where 11,200 new cases are recorded every year, one of the highest rates in the world. The majority of these tumours have a good prognosis -- 70-80% five-year survival after diagnosis -- and they do not infiltrate the bladder muscle at the time of diagnosis -- in around 80% of cases.

Outside influence: Genes outside nucleus have disproportionate effect

New research from the University of California, Davis, shows that the tiny proportion of a cell's DNA that is located outside the cell nucleus has a disproportionately large effect on a cell's metabolism. The work, with the model plant Arabidopsis, may have implications for future treatments for inherited diseases in humans.

CNIO researchers discover a new regulator of drug detoxification

Drug abuse and alcohol are some of the most frequent causes of liver damage, particularly in developed countries. Such kind of liver damage can cause irreversible liver failure and even cancer. Researchers from the Spanish National Cancer Research Centre (CNIO) have discovered an important new protective role of the Fra-1 protein, which neutralizes the damage caused by agents, such as the analgesic drug acetaminophen (Paracetamol). This is the first study to reveal a function of Fra-1 in protecting this important organ. The study is published today in the journal Hepatology.

Immune system discovery could lead to EBV vaccine to prevent mono, some cancers

Development of a vaccine against Epstein-Barr virus (EBV) has taken a step forward with the Canadian discovery of how EBV infection evades detection by the immune system.

EBV causes infectious mononucleosis and cancers such as Hodgkin's lymphoma and nasopharyngeal carcinoma, which is the most common cancer in China, as well as opportunistic cancers in people with weakened immune systems. A member of the herpes virus family that remains in the body for life, the virus infects epithelial cells in the throat and immune cells called B cells.

Disrupting an antioxidant pathway prevents heart disease caused by reductive stress

(SALT LAKE CITY)—University of Utah researchers have found that deficiency of an antioxidant response protein called nuclear erythroid-2 like factor-2 (Nrf2) delays or prevents hypertrophic cardiomyopathy, a type of a heart failure in which the heart muscle grows abnormally thick.

This new finding, published in the Oct. 1, 2013, issue of Cardiovascular Research, suggests that restoring the normal balance of reduction-oxidation chemical reactions in the body could prevent heart disease and other conditions caused by reductive stress.
