Melanoma is the most serious form of skin cancer, diagnosed in more than 50,000 new patients in the United States annually. While the rate of incidences continues to rise, survival rate has not improved and the race is on to find the genetic and cellular changes driving melanoma and to devise new means of detection and treatment. In a study published online in Genome Research, scientists have mapped chemical modifications of DNA in the melanoma genome, finding new markers that will help develop more effective treatment strategies to fight this disease. http://www.physorg.com/news165509319.html Medicine & Health Mon, 29 Jun 2009 15:49:20 EST news165509319 Scientists at Penn State have shed light on some of the processes that regulate genes -- such as the processes that ensure that proteins are produced at the correct time, place, and amount in an organism -- and they also have shed light on the evolution of the DNA regions that regulate genes. The team focused on regulatory regions that, when bound to the protein GATA1, are thought to turn on genes that play an important role in the development of red blood cells. "Our findings could help others to develop drugs to treat people who suffer from sickle-cell anemia and other blood disorders," said Ross Hardison, the T. Ming Chu Professor of Biochemistry and Molecular Biology and the team's leader. The results will be published on 1 December 2008 in the journal Genome Research. http://www.physorg.com/news146833211.html Biology Tue, 25 Nov 2008 11:00:11 EST news146833211 (PhysOrg.com) -- Scientists at Penn State have shed light on some of the processes that regulate genes -- such as the processes that ensure that proteins are produced at the correct time, place, and amount in an organism -- and they also have shed light on the evolution of the DNA regions that regulate genes.
