Data for: Jiadifenolide induces expression of cellular communication network factor (CCN) genes, and CCN2 possesses neurotrophic activity in neuronal precursor cells derived from human induced pluripotent stem cells

Jiadifenolide induces expression of cellular communication network factor (CCN) genes, and CCN2 possesses neurotrophic activity in neuronal precursor cells derived from human induced pluripotent stem cells Jiadifenolide has been reported to have neurotrophin-like activity in primary rat cortical neurons, and also possesses neurotrophic effects in neuronal precursor cells derived from human induced pluripotent stem cells (hiPSCs), as we have previously reported. However, the molecular mechanisms by which jiadifenolide exerts its neurotrophic effects in rat and human neurons are unknown. Thus, we aimed to investigate the molecular mechanisms and pathways by which jiadifenolide promotes neurotrophic effects. Here, we found that jiadifenolide activated cellular communication network factor (CCN) signaling pathways by up-regulating mRNA level expression of CCN genes in human neuronal cells. We also found that CCN2 (also known as connective tissue growth factor, CTGF) protein promotes neurotrophic effects through activation of the p44/42 mitogen-activated protein kinase (MAPK) signaling pathway. This is the first discovery which connects neurotrophic effects with CCN signaling.
