Inactivation of the Retinoblastoma 1 (RB) tumor-suppressor gene is a hallmark of cancer. Loss of RB function results in the transcription of genes required for cell growth but surprisingly also cell death. Profiling of RB-deficient cells showed that these cell death mRNAs are induced but not made into protein. Dr. Miles aims to identify the factors that block the production of cell death proteins and determine which of these factors prevent RB-lacking cancer cells from dying. As the RB pathway is disabled in almost all tumors, his research will provide insights into the mechanisms supporting cancer cell survival and as well as those preventing the death of cancer cells.
