A gene's first 'kiss' sets off that affair known as puberty

Puberty, that awkward phase when boys and girls are primed for their sexual reproductive years as men and women, appears to be triggered by the brain's own version of "It takes two to tango," whereby a signal literally gets turned on by a molecule that is produced by a gene aptly named KiSS-1. The couple ?a biochemical equivalent to Adam and Eve ?makes its sudden appearance in a region of...

Man and mouse share genome structures

In the most detailed large-scale study to date of the proteins that package DNA, researchers have mapped a family of switches that turn genes on and off. Their findings may help scientists understand regulatory mechanisms underlying cancer and human development. The research team includes first author Bradley Bernstein, recipient of a Howard Hughes Medical Institute (HHMI) physician postd...

Novel Asthma Study Shows Multiple Genetic Input Required; Single-gene Solution Shot Down

For patients with high-risk breast cancer treated with radical mastectomy and adjuvant chemotherapy, the addition of radiation therapy leads to better survival outcomes with few long-term toxic effects, according to a 20-year follow-up of a randomized trial, which appears in the January 19 issue of the Journal of the National Cancer Institute. The British Columbia randomized radiation the...

Genes In The Interferon System Important In Systemic Lupus Erythematosus

Two genes with very strong associations withthe disease systemic lupus erythematosus (SLE) have been identified bya team of scientists headed by researchers at the Department of MedicalSciences at Uppsala University. The findings are being published todayon the Web page of the highly prestigious American Journal of HumanGenetics. "These findings are probably the first genetic pieces of ahug...

Human Genome Project Achieves Technological Triumph

The completion of rough draft sequence of the human genes is a major scientific milestone and was achieved on 26.06.2000. The project began more than 10 years ago to map out almost 35 billion chemical letters that make up the recipe of human life. This breakthrough is expected to revolutionize the practice of medicine by paving the way for new drugs and medical therapies.Specific sequ...

Bypass Heart Surgery Performed Without General Anesthesia

A minimally invasive direct coronary artery bypass (MIDCAB) procedure was performed at Pittsburgh while the patient was awake. The operation was done under thoracic epidural anesthesia. This approach may help in discharging the patient early from the hospital. Dr. Zenati from the team of doctors who performed the surgery said that patients who are operated in this way may not have to go t...

PRIMARY PULMONARY HYPERTENSION GENE DISCOVERED

The discovery of the gene associated with the inherited form of primary pulmonary hypertension (PPH) by Drs. Jane H. Morse of Columbia University and James A. Knowles of the Columbia Genome Center is indeed a major breakthrough. Their study, funded in part by the National Heart, Lung, and Blood Institute at the National Institutes of Health and published in the September issue of th...

Blood Cells Capable of Regenerating Liver

Livers can be regenerated using stem cells from blood -- an important discovery that means patients may be able to grow their own liver transplants using bone marrow. This adds to a growing body of evidence that stem cells, known as "master cells" because they can produce a variety of different kinds of cells, might one day be manipulated to create custom-grown organ transplants....

Potential New Cancer Gene Identified

A Johns Hopkins University research team has discovered a new family of genes that contributes to the process of malignancy, shedding new light on the abnormalities that give rise to the aggressive childhood cancer, Burkitt's lymphoma - as well as lymphoma, leukemia, prostate, ovarian, lung, and breast cancer. Characterized by rapidly growing abdominal tumors, Burkitt's lymp...
