Effect of RR and HC-030031 on naringenin-induced CCK release. Cells were pre-incubated with 100 µM RR or 50 µM HC-030031 for 30 min before exposure to various concentrations of naringenin in Hepes buffer containing 1.2 mM Ca²⁺ at 37℃ for 60 min. Values are expressed as mean ± SEM from three separate experiments performed in triplicate (n = 9). ^*P < 0.05, ^**P < 0.01 vs. naringenin only.
