KISS1R signalling and physiological output in the hormone receptor-negative MDA-MB-231 and BT-20 cell lines MDA-MB-231 cells are metastatic when implanted in mice while BT-20 are not and remain epithelial-like We show that both cell lines express KISS1R mRNA and respond to KP-10 by elevating calcium mobilisation Interestingly, both cell lines displayed different complements of β-arrestin 1 and 2 expression. stimulate migration or pro-metastatic behaviour, as divergent responses were observed in the two TNBC lines

Additionally, we employed optical assays in living cells to thoroughly profile both GPR35 isoforms for constitutive and ligand-induced activation and signaling of 10 different heterotrimeric G proteins, ligand-induced arrestin recruitment, and receptor internalization. Our results reveal that the extended N-terminus of the long isoform limits G protein activation yet elevates and mechanistic insights of our study provide clues for the future design of isoform-specific GPR35 ligands
