Comments by David Sidransky, Johns Hopkins University School of Medicine

GAINING CREDIBILITY: David Sidransky's lab showed that methylation is an important mechanism of gene inactivation.
Although the phenomenon of methylation has attracted the attention of cancer researchers for some time, scientists have only recently recognized its potential role in the progression of human cancers. Methylation knocks out gene function; methyl groups placed on CpG islands (relatively rare clusters of cytosine and guanine bases connected by a phosphorylation site) effectively prevent gene transcription. If a tumor suppressor gene is methylated, cancerous growth may result. According to David Sidransky,...
