About this Seminar

Loss of skeletal muscle mass is associated with functional impairments, disability and increased mortality. Treatments to prevent muscle loss are an urgent unmet clinical need.  Therefore, understanding the mechanisms that regulate muscle mass will provide potential clinical targets to improve quality of life and survival of aged individuals, and those suffering from a wide variety of chronic disorders. In this seminar, Dr. Nader will present mechanistic evidence demonstrating that muscle anabolism is determined by the ability of the muscle to synthesize ribosomes. He will focus the discussion on the regulation of ribosomal DNA transcription by RNA Polymerase I and will provide evidence for a role of the mechanistic target of Rapamycin (mTOR) in both transcriptional and epigenetic regulation of rDNA genes. Dr. Nader will also discuss how alterations in proteostasis negatively impact rDNA transcription and muscle mass.
