dc.description.abstractAmyotrophic lateral sclerosis (ALS) is the most common fatal neurodegenerative disease, resulting in loss of voluntary muscle control, atrophy, paralysis, and eventually death. Although the pathophysiology of ALS is not completely understood, recent research in Dr. Chin's lab has identified alterations in skeletal muscle proteins in ALS mice. The purpose of this study was to investigate alterations in proteins involved in calcium handling (SERCA1 and SERCA2), endoplasmic reticulum (ER) stress (Grp78/BiP, PDI, and CHOP) and protein synthesis (Akt) in human ALS skeletal muscle. The ER chaperone protein Grp78/BiP and Akt, a protein involved in protein synthesis, were higher in ALS compared to CON. The calcium pump SERCA1 was lower in diaphragm compared to quadriceps muscles of ALS cases. These data highlight alterations in skeletal muscle proteins not only between ALS and CON, but also between different muscles in ALS, which are helpful for informing future research study designs.en_US
