Skeletal muscle carnitine loading increases energy expenditure, modulates fuel metabolism gene networks and prevents body fat accumulation in humans

…, BT Wall, K Marimuthu, CE Shannon… - The Journal of …, 2013 - Wiley Online Library
Key points • Carnitine is a substrate for the carnitine palmitoyltransferase 1 enzyme, a rate‐limiting
step in fatty acid oxidation within skeletal muscle. • Insulin stimulates carnitine …

Lipid-induced insulin resistance is associated with an impaired skeletal muscle protein synthetic response to amino acid ingestion in healthy young men

…, C Chee, BT Wall, AJ Murton, CE Shannon… - Diabetes, 2015 - Am Diabetes Assoc
The ability to maintain skeletal muscle mass appears to be impaired in insulin-resistant
conditions, such as type 2 diabetes, that are characterized by muscle lipid accumulation. The …

Relative contribution of intramyocellular lipid to whole-body fat oxidation is reduced with age but subsarcolemmal lipid accumulation and insulin resistance are only …

C Chee, CE Shannon, A Burns, AL Selby… - Diabetes, 2016 - Am Diabetes Assoc
Insulin resistance is closely related to intramyocellular lipid (IMCL) accumulation, and both

Increasing skeletal muscle carnitine content in older individuals increases whole‐body fat oxidation during moderate‐intensity exercise

C Chee, CE Shannon, A Burns, AL Selby… - Aging …, 2021 - Wiley Online Library
Intramyocellular lipid (IMCL) utilization is impaired in older individuals, and IMCL accumulation
is associated with insulin resistance. We hypothesized that increasing muscle total …
