Molecular studies of a family of genes are pruning branches from the old evolutionary tree.
Genetic studies confirm that one gene mutation plays a major role in inherited deafness; the importance of another genetic mutation is called into question.
HHMI researchers discover a gene responsible for triggering embryonic cells in the inner ear to develop into sound- and motion-sensing hair cells.
HHMI researchers have found a protein whose activity controls the shape of a developing organ.
HHMI researchers have discovered a molecule that resembles a component of snake toxins, but has a dramatically different effect on the nervous system.
Research to improve vaccines for infectious diseases must move forward. At the same time, according to HHMI investigator Barry Bloom, scientists should be perfecting vaccines that tackle pathogens associated with other diseases, such as cancer and heart disease.
Nitric oxide prevents programmed cell death by handcuffing the molecular executioner.
Studies of a molecule that causes severe weight loss in cancer patients may yield new drugs to treat obesity.
Two HHMI labs discover a new molecular road sign that directs axons to their proper destination in the central nervous system.
HHMI researchers find that the mahogany protein suppresses obesity and plays a role in the immune system.
With odorant receptor genes from Drosophila in hand, researchers hope to learn how odors influence behavior.
How does the nose discriminate between different odors?
HHMI researchers have developed a versatile method for improving binding properties of potential drugs.
HHMI researchers have identified a gene that influences formation of the chambers of the heart.
Mouse geneticists get a boost with the release of an encyclopedia containing more than 360,000 genetic sequences.
By studying flies that have mutations similar to some cancer patients, HHMI researchers have found a new type of tumor suppressor gene.
Dopamine transporter knockout mice developed by HHMI investigator Marc Caron and colleagues have provided a wealth of information about the molecular nature of some behavioral disorders.
A human cell surface protein that maintains the structural integrity of tissues is also the portal of entry for bacteria and viruses.
HHMI investigators have produced an image of the active form of the HIV enzyme reverse transcriptase. This work may clarify how mutations render HIV resistant to antiviral drugs.
A team of scientists from the Howard Hughes Medical Institute at the University of Chicago has found that a ubiquitous protein may explain how relatively sudden changes in body shape occur in a species.
Un equipo de científicos del Instituto Médico Howard Hughes en la Universidad de Chicago ha encontrado que una ubicua proteína puede explicar cómo se llevan a cabo los cambios relativamente repentinos en la forma del cuerpo de una especie.
The most common genetic cause of infant mortality happens because cells cannot properly process messenger RNA. The search for drugs to correct this defect is underway.
HHMI investigators have found a cellular target of survival signals that can override programmed cell death.
Genetic studies have uncovered a host of new genes involved in the formation of spores in yeast. The studies may illuminate germ cell production in vertebrates.
HHMI researcher Leonard Zon leads a team that has cloned a zebrafish anemia gene, producing one of the first fish models of a human disease. The achievement opens a new avenue for studying the genetics of human diseases.
