Is the Future of Genetic Testing on the Line?
from Clinical Laboratory News
Trying to follow the debate around gene patents can leave you wondering whether anyone is really talking about the same thing. On one side, it almost seems that elements of patientsí very bodies are somehow being traded by corporations, while from the other, gene patents are benign legal tools spurring innovation in the biotech industry, including molecular diagnostics. But clinical laboratorians and other scientists might feel squeezed in between, not totally comfortable with either characterization of what patenting a gene really means. More    E-mail article

from Reuters via Medscape Medical News
Although uncommon, progression to cirrhosis is possible in inactive carriers of hepatitis B virus (HBV), according to a report in The American Journal of Gastroenterology. The annual rate of reactivation of HBV was 1.55 percent, the authors report, and the annual rate of the development of cirrhosis in patients with reactivated hepatitis B was estimated to be 0.25 percent.

Cell Adhesion Molecule Predicts Joint Replacement with Arthritis
from Reuters via Medscape Medical News
High levels of vascular cell adhesion molecule 1 (VCAM-1) in the blood identify patients with osteoarthritis who are at increased risk for requiring hip or knee joint replacement, according to a new report. The results show that subjects in the highest VCAM-1 tertile were nearly four times more likely to undergo joint replacement in the future than were their peers in the lowest tertile (p < 0.001).

Experts Find New Targets to Stop Breast Cancer
from Reuters
One of the most aggressive forms of breast cancer may originate in the cells lining the mammary ducts, which can be targeted in the fight against the disease, experts in Australia say. Basal breast cancers account for 20 percent of all breast cancers and are among the most aggressive. They occur in women carrying mutations of the tumor-suppressing gene BRCA1 and have long been thought to originate in breast stem cells. More    E-mail article

Researchers Identify New Strain of HIV Derived From Gorillas
from CNN
French researchers have identified a new human immunodeficiency virus, the first derived from gorillas, a report said. The three previous HIV variants came from chimpanzees. The new findings indicate that gorillas, in addition to chimpanzees, are likely sources of HIV, the researchers concluded in a report published in the weekly Nature Medicine journal.

Leukemia Relapse After Stem-Cell Transplantation Due to "Genetic Trickery"
from Medscape Medical News
Italian researchers have described a series of patients with acute myeloid leukemia in whom the leukemic cells underwent some "genetic trickery" in order to escape immune surveillance, resulting in a relapse of the disease. More    E-mail article

Study: Immune Cells Cause More Post-stroke Brain Damage
from Reuters
Scientists have identified a class of immune cells that floods the brain soon after a stroke, causing inflammation and more neurological damage. In an experiment, Japanese researchers showed how mice that were deficient in these immune cells suffered far less brain damage after a stroke compared to normal mice. More    E-mail article
