Myokine Probdnf-P75ntr Signaling In Skeletal Muscle Injury And Sterile Inflammation, Katherine Aby
Dissertations and Theses
Originally discovered in the brain, brain-derived neurotrophic factor (BDNF) has been shown to be expressed and released from skeletal muscle as a myokine. However, the function of myokine BDNF is not fully understood. Of interest to this study is the function of the BDNF precursor proBDNF in skeletal muscle. We first show that skeletal muscle expresses unique BDNF splice variants compared to the brain, and at the protein level, skeletal muscle expresses significantly more proBDNF than mature BDNF under basal conditions. Consistent with this, expression of major protein convertases in skeletal muscle were significantly lower. The role of myokine proBDNF …

The Role Of Uchl1 In Skeletal Muscle Development And Regeneration, Ryan Antony
Dissertations and Theses
Ubiquitin C-terminal hydrolase L1 (UCHL1) is a deubiquitinating enzyme that was originally discovered in neurons. UCHL1 is also expressed in skeletal muscle, but its functions remain to be fully understood. Myogenesis is a critical process involved in embryonic development, growth, and regeneration following injury. Skeletal muscle injury is prevalent in trauma and surgical procedures, and skeletal muscle ischemia-reperfusion (IR) injury is a common yet dangerous public health problem. Here we reported that UCHL1 negatively affects muscle growth during aging as well as the regeneration process following IR injury. First, we observed that UCHL1 knockdown in C2C12 myoblasts resulted in increased …
