For protein identification, MS/MS peak lists were extracted (merge MSn scans with the same precursor at +/ 30 s retention time and +/ 0.05 m/z tolerance) and compared with the protein databases by using the Spectrum Mill MS proteomics workbench (Agilent Technologies, Rev B.04.00.127)
Concurrent measurements of metabolic markers, including BMI, HbA1c, fasting glucose, and insulin, were also obtained
As there is no meaningful expression of GLP-1 receptors on hepatocytes, the major effect of GLP-1 agonists on MASH is likely to be indirect and may be related to a reduction in calorie intake, body weight and insulin resistance, all of which would lead to reduced liver lipid accumulation and hepatic inflammation 7,8
