We selected the adenosine receptor 2B (A2BAR), specifically expressed in cancer cell lines compared with stromal cells, to explore the use of fluorescent ligands that can be used for target visualization. Fluorescent probes allowed semi-quantitative receptor mapping in living cells and validated the specific expression of A2BAR in CRC cell lines. a potential pharmacological tool in CRC, using selective antagonists, finding a reduction in tumor cell

In conclusion, we demonstrated that in GH3 cells SST2 and SST5 can form both homo- and hetero-dimers

Stimulation of AVPR2 with a selective agonist desmopressin promoted CRPC cell proliferation through cAMP In contrast, blocking AVPR2 with a selective FDA-approved antagonist, tolvaptan, reduced cell growth. Combinatorial use of AVPR1A and AVPR2 antagonists promoted apoptosis synergistically in CRPC cells. Furthermore, we found that castration-resistant cells produced AVP, the endogenous ligand for arginine vasopressin receptors, and knockout of AVP in CRPC cells significantly reduced proliferation suggesting
