Gene expression profiling aids in ovarian cancer prognosis
...artly dependent upon which genes are turned on and off
in tumor cells, researchers have long suspected that a better understanding of the genetic profile of the tumors of individual patients could help in making a more accurate prognosis. "With the advent of microarray analysi...
Antipsychotic drugs stop fatal viral infection in brain cells
... Atwood said. "These are generic drugs we can take off
the shelf that may help a lot of people." "It is likely that there are many other drugs with none of the potential side effects of antipsychotic drugs that will also block infection," said co-author Bryan Roth, professor of biochemistry at the Case S...

Random gene activation helps ulcer bug escape immune system

Down Syndrome protein reduces tumor growth

their production. Thus, DSCR-1 acts as a circuit breaker in agonist signaling, and serves in a negative feedback loop to inhibit endothelial cell activation and growth. More importantly, Dr. Minami and his colleagues discovered that when DSCR-1 is ov...
