Ancient mechanism for coping with stresses also gives cancer a boost

An ancient mechanism for coping with environmental stresses, including heat and toxic exposures, also helps cancerous tumors survive, reveals a new report in the Sept. 21, 2007, issue of Cell, a publication of Cell Press.

Discovery of cause of Job's syndrome

The rare immunodeficiency disorder known as Job's syndrome is caused by a specific genetic mutation that both overstimulates and understimulates the human immune system, leading to harmful bacterial and fungal infections and the physical features characteristic of the syndrome, according to two independent groups of scientists, one from the National Institutes of Health (NIH) and the other from the Tokyo Medical and Dental University.

Researchers provide genetic associations from a genome-wide scan for cardiovascular disease traits

Researchers from Boston University School of Medicine (BUSM), Boston University School of Public Health (BUSPH), and the National Heart, Lung and Blood Institute (NHLBI), have completed analyses of a genome-wide scan on a group of two generations of participants from the landmark Framingham Heart Study (FHS).

DNA microarray chips improved therapy in some patients with incurable cancer

Like many oncologists, Eric P. Lester, M.D., was faced with a dilemma: seven patients with advanced, incurable cancer, an arsenal of drugs that may or may not help them, and not enough solid proof about treatment efficacy to guide him.

Drug resistance gene has spread from East Coast to Midwest

A resistance gene that allows bacteria to beat an important class of antibiotics has started to appear in microorganisms taken from Midwestern patients, according to researchers at Washington University School of Medicine in St. Louis.

Researchers question genetic screening programs

The study by a team at Shaare Zedek Medical Centre in Jerusalem, is the first to examine what couples actually did when they learned their unborn child had a condition called Gaucher disease, an inherited condition which can be effectively treated.

Test for lung cancer looks for discomforting quiet among protective genes

When it is quiet – "almost too quiet" – in movies, it is a sign that something is about to go wrong for the good guys.

Re-engineered human T cells effectively target and kill cancerous B cells

Human white blood cells, engineered to recognize other malignant immune cells, could provide a novel therapy for patients with highly lethal B cell cancers such as acute lymphoblastic leukemia (ALL), according to researchers at Memorial Sloan-Kettering Cancer Center (MSKCC).

New cell death pathway involved in sperm development

Heavy and bulky sperm would not be good swimmers. To trim down, sperm rely on cell death proteins called caspases, which facilitate the removal of unwanted cellular material and radically remodel these cells into their sleek, light shape.

Gene profiling can single out the worst cases of multiple myeloma and guide therapy

Multiple myeloma patients vary widely in how they respond to treatment, but now researchers at the Myeloma Institute for Research and Therapy at the University of Arkansas for Medical Sciences have identified a small subset of genes whose activity could predict high-risk cases and potentially guide therapy in the future.
