Weight reduction itself provides cardiovascular benefits and can improve overall quality of life for many people
Thyroid C-cell tumor signals observed in rodent studies have not been confirmed in human data, but the boxed warning remains for both classes
Membranes were sequentially incubated with primary antibodies (anti-GLP-1 [Santa Cruz, sc-80603, 1:1,000], anti-MPC2 [Proteintech, 20049-1-AP, 1:2000], anti-GAPDH [Cell Signaling, D4C6R-97166, 1:5,000]) overnight at 4 C, followed by HRP-conjugated secondary antibodies (Santa Cruz, sc-2354, 1:5,000) for 1 h at RT
