Scientific Interests

Dr. John Adams is Director of the Orthopaedic Hospital Research Center, where he is charged with building an interschool (the College and School of Medicine), multidisciplinary program of research in musculoskeletal sciences. His bench-to-bedside (translational) and clinical research efforts are targeted at understanding

  1. the concerted role of heterogeneous nuclear ribonucleoproteins and heat shock proteins in hormone-directed chromatin remodeling, transcription, transcript splicing and miRNA regulation of mRNA handling,
  2. the role of vitamin D in the human innate and adaptive immune response, and
  3. the contribution of human vitamin D insufficiency to states of immuno-insufficiency and abnormal skeletal and energy homeostasis.
