The Role Of Skeletal Muscle-Synthesized Brain Derived Neurotrophic Factor In The Maintenance Of Motor Neuron Mitochondrial Populations, Mikel Cawley
All NMU Master's Theses
Mitochondria are essential for the high energy demands of the neuromuscular junction and, as a consequence, leave motorneurons susceptible to dysfunction. A potential origin of progressive pathology may be a reduction in brain-derived neurotrophic-factor (BDNF) signaling at the motor unit. We have shown that mice deficient in skeletal muscle-synthesized BDNF (msBDNF) demonstrate progressive motorneuron and muscle pathology at 120d. We hypothesize mitochondrial populations will be altered in motorneurons of msBDNF deficient-mice. At 117d, msBDNF deficient-mice received intramuscular injections of MitoTracker™ dye targeting the right gastrocnemius muscle. At 120d experimental groups underwent a gastrocnemius harvest or a sciatic nerve ligation protocol …
Serum-Based Biomarkers And Magnetic Resonance Imaging Following Mild Traumatic Brain Injury In Collegiate Athletes Post Return-To-Play, Taylor R. Susa
Serum-Based Biomarkers And Magnetic Resonance Imaging Following Mild Traumatic Brain Injury In Collegiate Athletes Post Return-To-Play, Taylor R. Susa
All NMU Master's Theses
Recently there has been an increase in the use of MRI (Magnetic Resonance Imaging), to measure the effects of traumatic brain injury (TBI). Proteins such as BDNF, S100B, UCH-L1, and Tau have been found to have altered levels in blood serum after TBI. However, there is limited knowledge about the relationship between serum-based and MRI-based biomarkers in concussed athletes post return-to-play. This study aimed to bridge this gap by collecting serum samples from 42 participants across two groups. The first group (n = 21) consisted of recently cleared to return-to-play collegiate athletes after experiencing a sports-related concussion. The second group …

Motor protein-based active transport is essential for mRNA localization and local translation in animal cells, yet how mRNA granules interact with motor proteins remains poorly understood. Using an unbiased yeast two–hybrid screen for interactions between murine RNA-binding proteins (RBPs) and motor proteins, here we identified protein interaction with APP tail-1 (PAT1) as a potential direct adapter between zipcode-binding protein 1 (ZBP1, a β-actin RBP) and the kinesin-I motor complex. The amino acid sequence of mouse PAT1 is similar to that of the kinesin light chain (KLC), and we found that PAT1 binds to KLC directly. Studying PAT1 in mouse …
