Vanderbilt's Program in Human Genetics will play a key role in identifying genes involved in common diseases, with initial focus on depression and sepsis. The program will utilize cutting-edge technology to analyze DNA samples and develop targeted treatments.
Researchers at Vanderbilt University Medical Center are exploring the role of aspirin and similar drugs in preventing colon cancer. They will study the mechanism of COX2 inhibition and its potential as a therapeutic target for colon cancer prevention.
Researchers at Vanderbilt University Medical Center have identified a critical molecular link between endothelial cells and the development of new blood vessels. This discovery could lead to more targeted treatments for heart disease and cancer with fewer side effects.
Researchers reveal that the Type III TGF-beta receptor plays a crucial role in transforming heart cells and forming valves, providing new insights into congenital heart defects. The discovery could lead to improved treatments for children with heart defects.
A new study published by Vanderbilt University Medical Center researchers found that estrogen replacement therapy (ERT) does not significantly elevate the risk of breast cancer in women with histories of benign breast disease. Women already face a higher risk, but ERT does provide benefits for heart and bone health.
A new study found that women under 65 with certain chronic medical conditions experience substantial morbidity and mortality from acute cardiopulmonary events during influenza season. The study suggests that stronger efforts to reach younger high-risk patients are needed to improve influenza vaccination levels.
Researchers at Vanderbilt University Medical Center discovered that mice lacking the EP2 receptor exhibit salt-sensitive hypertension and reduced fertility. The study found that PGE2 excretion increased in response to high salt diets, leading to unmasked constrictor receptors and development of hypertension.
Researchers discovered that Endermologie, a non-invasive treatment, creates collagen bands parallel to the skin surface, leading to smoothing of cellulite. The study found no evidence of fat metabolism or new blood vessel formation.
The Institute for Coffee Studies will investigate the effects of coffee on the brain, depression, and alcohol dependency. Researchers aim to identify potential medicinal compounds in coffee that could benefit human health, with a focus on chlorogenic acids and their impact on neurotransmitter systems.
Researchers at Vanderbilt Cancer Center found that overproduction of TGF-beta contributes to tamoxifen resistance. They also discovered the importance of immune system's natural killer activity for tamoxifen's effectiveness. This discovery may lead to strategies to prolong tamoxifen response or even reverse resistance.
Researchers discovered that cells in the sensory cortex can sprout new axons and form connections with unimpaired areas of the brain, potentially allowing for recovery from stroke or injury. This newfound ability could lead to breakthroughs in treating brain disorders such as spinal cord injuries or stroke.
Researchers have created a transgenic mouse model of Huntington's disease, exhibiting progressive behavioral and motor dysfunction. The mice developed similar neuropathological changes to those seen in human Huntington's disease, with symptoms worsening as the abnormal gene load increased.
Researchers found that tumors with a specific BRCA2 mutation are more sensitive to radiation and certain chemotherapy drugs. This suggests genetic screening could be used to tailor treatment for patients with this mutation, potentially improving outcomes.
Researchers discovered a gene linked to hydrocephalus and glaucoma in mice, which is also associated with other birth defects. The gene, called mouse forkhead 1 (mf1), produces an incomplete protein that can cause abnormalities in the brain, eyes, and kidneys.
