Introduction: Substrate accumulation, energy deficiency or complex molecule defects characterize inherited metabolic disorders (IMDs), accounting for their multi-system manifestations. One important aspect of this is endocrinopathy, which is relatively common but underestimated in IMDs, presenting in childhood following diagnosis or sometimes a presenting symptom in adults where there is multi-system or multi-gland involvement. Endocrinopathies may be secondar...

Introduction: GH is widely abused by athletes for its anabolic and lipolytic properties. As the tests for detecting GH abuse develop further, it is possible that athletes will exploit IGF1 as an alternative or additional doping agent. There is currently no evidence to suggest that IGF1 administration improves athletic performance.Objectives: To determine the effects of rhIGF1/rhIGFBP3 administration on body composition and physical fitness in recreationa...

Background: Thyroid hormone (TH) action is mediated by TH receptors (TRs) α&β. Both regulate gene expression by binding TREs on the DNA (canonical signaling) or activate cellular signaling pathways (noncanonical signaling). Bone is a major TH target and noncanonical TR α & β effects on bone metabolism were suggested. We studied mouse model bones to distinguish between signaling types.Methods: Growth of WT mice and mice with ei...
