Research Summary:
The body must maintain a pH within a narrow range (7.4±0.05) to sustain life. However, many factors such as kidney disease, diabetes, metabolic diseases, and diet can shift this pH outside the acceptable range. To counter these variations, the body employs a variety of regulatory mechanisms. Although musculoskeletal regulation of pH has been previously reported, the mechanisms by which muscles and bones control acid-base balance are unknown. My lab will focus on elucidating the relationship between the musculoskeletal system and the acid/base balance in the body. I hypothesize that degradation of muscle, bone, and tendon directly regulates pH at the (1) cellular, (2) local, and (3) systemic levels. This understanding will create a foundation of knowledge for developing therapeutic treatments for diseases such as osteoporosis, muscle wasting, and metabolic acidosis.
