To address these issues, Dr. Meltzer and colleagues utilize several genomic technologies, especially DNA microarray hybridization.

Philipp Oberdoerffer, Ph.D.
Genomic instability and changes in gene expression are conserved hallmarks of eukaryotic aging. The accumulation of mutations and chromosomal aberrations, as well as the progressive loss of "youthful" gene expression patterns, have been associated with altered cell function and a greater propensity for age-related diseases, including a variety of neurodegenerative disorders and malignant transformation. The potential of DNA damage to affect cell function both through direct DNA alterations and through indirect, epigenetic changes in chromatin structure puts it at a critical position to influence the aging of eukaryotes. The long term goal of Dr. Oberdoerffer's group is to understand how DNA damage and its repair affect the (epi-)genome over a lifetime, and how these changes impinge on tissue homeostasis, cancer and aging.

Shalini Oberdoerffer, Ph.D.
Alternative pre-mRNA splicing is a major mechanism of transcriptome diversification in cells of the immune system. The goal of Dr. Oberdoerffer's laboratory is to study the extent and mechanism by which trans-factor mediated global shifts in alternative pre-mRNA splicing occur.
