CCK-8 (orange, 2 g/kg body weight) or vehicle (black) injection on cumulative ad libitum food intake in 12- to 18-week-old male WT ( G ) and Bbs5 / ( H ) mice over 24 hours ( n = 79 per group)
First, GLP-1RA can activate the first messenger adenylate cyclase (AC) after binding to the receptor, which stimulates an increase in the secretion level of the intracellular second messenger cyclic adenosine phosphate (cAMP) and subsequently activates the intracellular secondary messenger protein kinase A (PKA) (48)
This is why a thorough screening process is so vital
For the measurement of the cell-internalized activity, the surface-bound radioactivity was removed by incubation with acid stripping buffer (50 mmol/L glycineHCl/100 mmol/L NaCl, pH 2.8) at room temperature for 20 min
The solution was incubated at 37 C and samples collected at timepoints [0, 1, 2, 4, 8, 12 h]
If compounded options are discussed, it should be with full transparency and proper medical supervision
