Read About Dr. Costello's Current Research ►

Dr. Costello's laboratory investigates the role of genetic and epigenetic alterations in the development of sporadic cancers, with a focus on brain tumors. Most sporadic cancers have been described by molecular pathways involving gain and loss of chromosomal regions corresponding to oncogene activation and tumor suppressor gene inactivation, respectively. Such genetic characterizations of sporadic tumors do not take into account epigenetic alterations that may similarly result in abnormal loss or gain of gene activity. Methylation of cytosine in DNA is such a modification that can influence gene expression and chromosome stability. Although DNA methylation patterns can be significantly altered in human cancers, such changes are not detected by typical genetic screening methods.

The Costello lab uses a DNA fingerprinting technique termed Restriction Landmark Genomic Scanning (RLGS) to simultaneously assess the genetic and epigenetic (methylation) status of thousands of gene-associated CpG islands. Their studies have shown that in many human tumor types, the pattern of methylation of CpG island-containing genes is non-random and displays distinct tumor type-specificity. Further results suggested that there are a large number of genes in which methylation, rather than genetic alteration, is the primary mechanism of inactivation. These findings support the proposal that many potentially important cancer genes have remained undiscovered for decades due to the exclusively genetic screening methods used. It is now critically important to identify these genes to determine how the aberrant methylation contributes to malignancy.
