Part 1 – Cigall Kadoch, Ph.D. (30 min.)
Exome- and genome-wide sequencing studies in human cancer have revealed a striking frequency of mutations in the genes encoding subunits of the mammalian SWI/SNF (BAF) family of ATP-dependent chromatin remodeling complexes. We recently determined these mutations to be broadly recurrent in over 20% of all cancers. I will present studies focused on the assembly and topological architecture of mammalian SWI/SNF complexes, cancer-specific complex subunit and associated protein factor composition, and novel approaches toward the identification of small molecule therapeutics for this class of human tumors.
Part 2 – Chris Fry, Ph.D. (30 min.)
The robustness and reliability of chromatin immunoprecipitation (ChIP) and ChIP-seq data is highly dependent on the quality of the antibodies and chromatin preparation used in the immunoprecipitation. I will provide an overview of the development and validation of new high quality recombinant rabbit monoclonal antibodies that show improved specificity, sensitivity, and reproducibility in ChIP and ChIP-seq assays. In addition, I will discuss important factors to consider for optimizing different types of target proteins, including histones, transcription factors, and transcription cofactors.
