The Rosetta Institute of Biomedical Research is an independently funded medical research institute founded by Dr. Ryan Holzer, PhD. The institute is funded by internally generated revenue, and by private donations. We conduct basic and translational research on apoptosis in multiple myeloma and other malignancies. Current research projects include discovering novel mechanisms of bortezomib (Velcade) resistance in multiple myeloma, characterizing proapoptotic signaling pathways activated by Type 1 interferon, the identification and characterization of ubiquitin ligases that regulate cell survival, transcriptomic analysis and miRNA profiling of clonal evolution in cancer and the discovery of novel roles for IL-6 family cytokines in hematologic malignancies. A variety of techniques are being used at the institute to address these questions, including bioinformatic analyses, CRISPR/Cas9 gene editing, tissue culture and mouse models of cancer.
