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...

Newly Discovered Compound Blocks Known Cancer-Causing Protein

Duke Comprehensive Cancer Center scientists have discovered a potential new drug that inhibits destructive cell signals that drive the growth of one-third of all cancers. The scientists showed they could block the growth of cultured colon cancer cells using this new compound, called cysmethynil. Their finding, reported in the March 22, 2005, issue of Proceedings of the National Academy of...

Scientists identify molecule that regulates well-known tumor suppressor

Scientists have discovered that a molecule called DJ-1 is likely to be involved in the generation of human tumors through negative regulation of the well-known tumor suppressor, PTEN. The research, published in the March issue of Cancer Cell, has important implications for determining the prognosis of some human cancers, and may prove to be a suitable target for cancer therapy. The phospha...

Researchers say most of these patients were also...

Little Known DNA Repair Enzyme May Be A Tumor Suppressor Gene

Researchers at the University of Pittsburgh have demonstrated that loss of DNA // repair enzyme’s activity in mouse cells leads to dramatic chromosomal instability. The DNA in our cells is constantly subject to environmental, chemical and cellular impacts. Thanks to nature, our cells contain several enzymes dedicated to detecting and repairing any damage caused by these impacts. Failu...
