Research Description

Our lab studies (a) the regulation of DNA replication in normal and cancer cells using genetics and genomics, (b) the DNA damage response of a mammalian cell and (c) the role of small RNAs (including microRNAs) in control of cell proliferation.How DNA replication is initiated in human cells, and how dysregulation of this process leads to the genomic instability seen in cancers has been a major theme of research over the last two decades. We are also interested in how tumor suppressor genes and chromatin remodeling factors co-ordinate the response of a cell to DNA damage to prevent the appearance of mutations in the progeny. Finally, we are exploring the role of microRNAs in cell-cycle regulation with an emphasis on microRNAs that inhibit cell proliferation.

Following are some references for the research being conducted in our lab according to the area of research.

GENOMICS

The ENCODE program is the post-genomics program initiated by National Human Genome Research Institute to annotate the human genome. We use genome tiling microarrays to determine origins of replication, replication profile, replication factor binding sites and epigenetics of the human genome. Obviously the next step will be to see how these are changed in cancers. (http://genome.bioch.virginia.edu/encode)

 CANCER GENOMIC INSTABILITY

that stems from an imbalance of replication factors

RESPONSE TO DNA DAMAGE

that stems from abnormalities of DNA replication or from external agents such as chemotherapeutic agents or radiation. The response pathways often use tumor suppressor proteins like p53, Fanconi Anemia complex or BRCA1. A related area of research focuses on two putative AAA+ ATPases (Rvb1 and 2) that are part of the TIP60 chromatin-remodeling complex that responds to DNA damage.

DETECTING GENOMIC INSTABILITY

in cell lines and cancers by ultra highthroughput DNA sequencing.

MICRO-RNAs

We are examining how the new "dark matter" of the genome, microRNAs and newly discovered non-micro-short RNAs, regulate cell proliferation and differentiation in muscle differentiation and in prostate cancer cells.
