Human embryonic stem cell-derived motor neurons are sensitive to the toxic effect of glial cells carrying an ALS-causing mutation
For example, cholesterol oxidation derivatives, such as 7-hydroxycholesterol and 7-ketocholesterol, are significantly elevated in sarcopenia patients and exert cytotoxic effects on myoblasts and myotubes ( 2.4 Factors that aggravate lipid peroxidation Lipid peroxidation drives the pathological progression of sarcopenia through free radical reactions in conditions such as aging, disuse atrophy, denervation, and chronic diseases
Since mitochondrial defects have been broadly observed in many different diseases in which TDP-43 pathology is commonly detected, and because mitochondria are crucially important for maintaining metabolomic homeostasis, one of the key questions that remains unanswered is: What are the metabolomic changes that occur with respect to TDP-43 pathology? We investigated the metabolomic perturbations that occur in the motor cortex of prp-TDP-43 A315T mice, a mouse model which recapitulates many aspects of TDP-43 pathology observed in ALS and ALS/FTLD patients 19
Preliminary experiments on murine models suggest that Ipamorelin may have mitigated the loss of muscle strength, which can occur in artificially-induced catabolic conditions
