Briefly, while the extracellular domain (ECD) of GLP-1R, which is responsible for ligand recognition and specificity, engages the C-terminus of the GLP-1, the interhelical transmembrane crevice of the GLP-1R helps in docking of the N-terminus of the GLP-1, triggering downstream signaling ( FIGURE 2 However, the naturally secreted GLP-1 is quickly hydrolyzed and rendered inactive by dipeptidyl peptidase-4 (DPP-4), a transmembrane amino peptidase
Quantitative real-time polymerase chain reaction (qRT-PCR) was performed using SYBR Green Real-time PCR Master Mix (Toyobo, Osaka, Japan) on a Quant-Studio 1 Real-Time PCR System (Applied Biosystems)
The fundamental principle is to maintain the product within its labelled temperature range throughout the journey and to avoid freezing or excessive heat exposure
