Dormant Cancer Cells Rely on Cellular Self-cannibalization to Survive
from Science Daily
A single tumor-suppressing gene is a key to understanding, and perhaps
killing, dormant ovarian cancer cells that persist after initial
treatment only to reawaken years later, researchers at the University
of Texas M. D. Anderson Cancer Center report in a recent issue of
Journal of Clinical Investigation. The team found that expression of a
gene called ARHI acts as a switch for autophagy, or
self-cannibalization, in ovarian cancer cells. More
Celgene Warns that Anticlot Drug Innohep may be Linked to Deaths
from FDA MedWatch
A drug used to treat blood clots formed primarily from deep vein
thrombosis or in kidney failure increases the death rate among elderly
patients, its maker has warned physicians. The biotech company Celgene
Corp. has alerted doctors in a letter on the U.S. Food and Drug
Administration Web site, stating that clinical trials using the drug
Innohep showed a death increase incidence in patients over age 70 of 13
percent, compared to a death rate of five percent when another
anti-clotting drug, Heparin, was used. More
Study Links Osteoporosis Drugs to Jaw Trouble
from The Washington Post
The proportion of people taking widely prescribed oral osteoporosis
drugs who develop a nasty jaw condition may be much higher than
previously thought, a new study suggests. Previous reports had
indicated that the risk of developing osteonecrosis of the jaw from
bisphosphonates in pill form were "negligible," although there was a
noted risk in people taking the higher-dose intravenous form of the
drug. More
Grape-seed Extract Kills Laboratory Leukemia Cells, Proving Value of Natural Compounds
from Science Daily
An extract from grape seeds forces laboratory leukemia cells to commit
cell suicide, according to researchers from the University of Kentucky.
They found that within 24 hours, 76 percent of leukemia cells had died
after being exposed to the extract. The investigators, who report their
findings in the recent issue of Clinical Cancer Research, also teased
apart the cell signaling pathway associated with use of grape seed
extract that led to cell death, or apoptosis. More
Lab Research: Lose the Mice
from KCEN-TV
Laboratory mice have played a huge rule in many of medicines most
important breakthroughs. But a new era may be dawning in the world of
lab research, one that may mean fewer mice and more humans.
Immunologist Mark Davis, Ph.D., a researcher at Stanford University in
Palo Alto, Calif., says the time has come for immunologists to start
weaning themselves off of experimental rodents and to embark on bolder
research of the causes and treatments of human-specific diseases. More
Linking Disease to Gene Variations
from Genetic Engineering & Biotechnology News
As researchers and clinicians continue to unravel the mysteries of the
human genome, they are looking to technology companies to provide
next-generation sequencing and genome analysis tools to accelerate
whole-genome and targeted DNA sequencing, SNP genotyping, and
copy-number variation (CNV) analysis. More
Doctor Used Patients' Liposuctioned Fat as Car Fuel
from Medical News Today
A plastic surgeon who practised in Beverly Hills, California, is being
accused of using human fat liposuctioned from former patients to fuel
his car. According to Forbes.com, Alan Bittner allegedly collected the
human fat and turned it into biodiesel for his own SUV and his
girlfriend's car. He is being investigated by California's public
health department. More
Hospital Investigates "Possible Infection Threat"
from WSMV-TV via MSNBC
If you've had a colonoscopy at the Veterans Administration Hospital in
Murfreesboro, Tenn., you may be at risk of infection from the equipment
they used. The hospital has known of a potential problem since Dec. 1. More
Bacteria Could Limit Dengue Spread
from The Wall Street Journal
The simple model of mosquito-borne illness: A mosquito eats a blood
meal from an infected person, then passes on the disease when it bites
someone else. But the simple model omits a key piece in some disease
stories. The bug causing the illness has to incubate inside the
mosquito for a while — about two weeks in the case of dengue — before
the mosquito infect other people. More
Scientists Identify New Congenital Neutropenia Syndrome and Causative Gene Mutation
from Infection Control Today
A team of scientists has discovered a new syndrome associated with
severe congenital neutropenia, a rare disorder in which children lack
sufficient infection-fighting white blood cells, and identified the
genetic cause of the syndrome. Severe congenital neutropenia is a rare
disorder, with an incidence of less than one in 200,000 births. More
