We employ modern technologies - genomics, proteomics, mouse models, multi-color digital imaging, etc. to study cancer mechanisms. We have made major contributions to our understanding of the tumor suppressor ARF and p53 and the oncoprotein Mdm2.
Our lab is interested in how dynamic changes in chromatin structure affect gene expression, cell lineage determination and cancer development. Currently, we are focusing on two epigenetic modifications, DNA methylation and histone methylation.
We recently found that nociceptive (pain-sensing) circuits in mammals are highly organized at molecular and neuroanatomical levels. In our laboratory, we are using molecular, genetic, electrophysiological and behavioral approaches to study these pain circuits in mice. Our ultimate goal is to identify new analgesics so that debilitating chronic pain conditions can be more effectively treated.
Techniques used in our lab include: Molecular biology and cell culture; In situ hybridization and immunofluorescence staining; Construction and characterization of knock-in and transgenic mice; Mouse behavioral experiments; Bioinformatics; FACS of neurons; Expression profiling with
Affymetrix GeneChip arrays; Calcium imaging; Patch Clamp Electrophysiology.
