Tobacco Breath Saves Hornworm Caterpillars From Predators
Your morning breath has nothing on the tobacco hornworm. Researchers at the Max Planck Institute of Chemical Ecology in Germany have found a gene that allows the caterpillar to take the nicotine in its diet and puff it into predators' faces to keep them at bay. The research is published in today's
New Hope for Brain, Spinal Cord Injuries
FRIDAY, Dec. 11 (HealthDay News) -- Deleting a gene that suppresses natural growth factors enables regeneration of injured nerve fibers (axons) in mice, a new study shows. The finding may lead to new treatments for people with brain and spinal cord injuries. Researchers at Children's Hospital
In Time, Cream Might Prevent Herpes Transmission
WEDNESDAY, Jan. 21 (HealthDay News) -- A topical treatment that disables genes that play a key role in the transmission of the herpes virus has been developed by U.S. researchers. The treatment uses RNA interference (RNAi) to fight the virus in two ways: by disabling its ability to replicate and by
Gene Tweaks and the Male Pill: Contraception of the Future?
The Pill. Condoms. Intrauterine devices. They are staples of modern birth control. And while they represent some of the best options that men and women have at their disposal today to prevent pregnancy, each is decades old -- and comes part and parcel with a number of its own drawbacks. "We want
Low Levels of 2 Enzymes in Ovarian Cancer Cells Shortened Survival
Finding could lead to new treatments for this deadly disease, researchers say.
Blocking Oncogene Can Stop Spread of Ovarian Cancer
MONDAY, Dec. 15 (HealthDay News) -- Blocking proteins produced by the oncogene MYC can stop the spread of ovarian cancer, researchers say. An oncogene is a gene that has the potential to help cause cancer. In up to 60 percent of human ovarian tumors, MYC is overly active. This causes the ovarian
Colon Cancer Oncogene Discovered
SUNDAY, Sept. 14 (HealthDay News) -- Researchers have identified a new genetic player in the development of colon cancer. The findings implicate CDK8, a protein that regulates gene expression in the proliferation of colorectal cancer, the researchers found. Should the results be validated, they
Gene Linked to 'Dry' Macular Degeneration
Study also uncovers risks associated with treating 'wet' form of the eye disease.
One Gene May Be Key to Myeloma
The discovery holds promise as a treatment target for this diverse disease, experts say.
Researchers Tackle HIV From a New Angle
TUESDAY, April 29 (HealthDay News) -- Most drugs aimed at suppressing HIV target proteins lying on the virus itself, but new research suggests that focusing on the human host's immune cells might work even better. That's because human cells mutate at much slower rates than does HIV, so the virus
