Bilobalide exhibits many biological activities, but its effects on morphine stimulation have not been elucidated. The research aims to explore the function and underlying mechanisms of bilobalide in morphine-led hippocampal neuron cells. Cells were treated with or without morphine or oxaliplatin (OXA), bilobalide, or SCH772984 dilutions. miR-101 inhibitor and negative control were transfected into cells. Western blot and quantitative reverse transcription-polymerase chain reaction were, respectively, conducted to measure the relative expression of proteins or RNAs. Morphine improved the expression levels of orexin1 receptor (OX1R) and c-FOS, the p/t-ERK/PKC as well. The c-FOS protein level and p/t-ERK/PKC were significantly elevated by morphine + OXA. Bilobalide had no effect on OX1R and p/t-PKC but evidently decreased the c-FOS and p/t-ERK. The p-ERK and the c-FOS accumulation levels were remarkably reduced by SCH772984. The production of miR-101 was promoted by bilobalide but inhibited by the miR-101 inhibitor. miR-101 inhibitor abolished bilobalide's inhibitory effects on p/t-ERK. Bilobalide exhibited morphine-induced effects on hippocampal neuron cells by upregulating miR-101.
