Does cancer run in families?

...Iceland's National-University Hospital go some way toward answering that question. They analyzed comprehensive data on the most common forms of cancer from Iceland's National Cancer Registry in the context of deCODE's nationwide genealogy database. This enabled Dr. Amundadottir and her team to establish how...

'From the Sidelines' describes the making of a scientific revolution

...singer's earlier research made major contributions toward deciphering the genetic code, understanding the nature of frameshift mutations, and the structure of the T4 phage genome.

Brain tumor study reveals why treatment efforts fail in genetic disorder

...pies." The research team already has made progress toward that goal. Too much RAS and too little Nf1 are both known to result in a cascade of events, including activation of another protein called Rac1, which in turn activates LIM kinase. Gutmann and his colleagues found that that effect could be mimicked i...

Protein in urine may warn of preeclampsia risk in pregnant women

...ith another important piece of evidence as we work toward developing the means to diagnose, and eventually to treat, this serious condition," says Benjamin P. Sachs, MBBS, DPH, Chairman of the Department of Obstetrics and Gynecology at BIDMC and an investigator on the study. "This is of especially critical ...

Healthy cleavage: How statins protect against Alzheimer disease

...ight modulate APP processing and shift the balance toward "healthy" (non-amyloidogenic) cleavage. In their quest to understand how statins affect APP processing, Gandy and colleagues focused on a molecule called ROCK, a kinase enzyme that had recently been implicated in APP processing. Working in mouse n...

New cancer gene identified by Memorial Sloan-Kettering scientists

... a main switch in the molecular network that leads toward cancer," Dr. Pandolfi added. "If we could turn Pokemon off, it may block this oncogenic circuitry and stall the malignant process." The investigators confirmed Pokemon's cancer-causing role by inserting the oncogene into mice. Pokemon does its damage...

By age 6, children of overweight mothers are also prone to obesity

The fact that increased body weight at age four is followed by increased body fat at age six indicates that prevention efforts should begin by age four for overweight children of overwe...

NYU biologists find new function for pacemaker neurons

They not only relay visual signals to target cells, but are also act as filters, using their molecular clocks to adjust the intensity of the transm...

Parents' attitudes to sperm donation still some concerns about being open

In patients who become anemic, blood transfusions replenish the red blood cell supply in the body. The team further found that differences among patients in their ability to process nitric oxide in ...

New insight into regulation of blood stem cells

Scientists have made a significant advance toward understanding the regulation of blood stem cells and the complex, lifelong process of blood cell formation. A research study published in the February issue of Developmental Cell expands on previous studies by using adult animals to examine the role ...
