From a Lowly Yeast, Researchers Divine a Clue to Human Disease

...teinmetz, compared normal yeast to a strain with a mutated form of Sen1 that does not see the stop signal. "The Sen1 mutant reads right through the stop sign and keeps going," Brow says. Without a properly functional Sen1, RNA polymerase II "reads through" the end of the gene and builds longer and longer R...

Regulatory Mechanism for Tumor Suppressor Protein Identified

...out the body, the p53 protein has been found to be mutated and dysfunctional in more than half of human cancers. When working properly, p53 acts by binding to DNA to activate genes that direct cells with damaged DNA to cease dividing until the damage can be repaired. Cells with such damage include cancer cel...
