Fig. 1 Fig. 1. Calcium imaging in zebrafish embryos. The developing trunk muscle (DTM) of 48 h post-fertilization (hpf) zebrafish embryos were used to test the rapid effects of cortisol on Ca2+ dynamics using the FURA-2AM method. The treatments included cortisol antibody to sequester cortisol, EGTA to chelate extracellular Ca2+ (eCa2+), BAPTA-AM (BAPTA) to chelate intracellular Ca2+ (iCa2+), and RU486 as a GR antagonist. Also, Ca2+ channel blockers, including nifedipine (Nife) to block L-type channel, verapamil (VM) to block T-type channel, cadmium as a non-specific blocker of plasma membrane Ca2+ channels, and CpD5J-4 to block the CRAC channels were utilized. See materials and methods for details.
