 The study aims to provide an easily accessible M-INA profile of endogenous signaling repertoire in four commonly used cell lines for GPCR research, HEK293, ATT20, BV2, and N18. Microarrays were utilized to measure the M-INA levels of a comprehensive profile of non-chemosensory GPCRs and over 100 GPCR signaling related gene products in these cell lines. The results provide valuable information for researchers to choose the most appropriate cell line for studying GPCRs and related signaling proteins, as well as better understanding potential interactions between them.
