Abstract:

INTRODUCTION: Oxidative stress and cell apoptosis have both been suggested to be closely associated with the pathogenesis of Parkinson's disease (PD). Previously, bisdemethoxycurcumin (BDMC) has been shown to exhibit several desirable characteristics as a candidate neuroprotective agent, including antioxidant and anti-inflammatory activities in the nervous system. However, whether BDMC can exert cell-protective roles in an in vitro model of PD remains unknown.

MATERIAL AND METHODS: SH-SY5Y cells were pretreated with BDMC, with or without AG490 and SI-201, for 30 min, followed by a co-incubation with rotenone for 24 h. Subsequently, a cell viability assay and western blotting was performed, and SOD and GSH activities were analyzed.

RESULTS: The results revealed that the pretreatment with BDMC enhanced the cell survival, antioxidative stress capacity and the phosphorylation levels of JAK/STAT3 in SH-SY5Y cells treated with rotenone. However, following the incubation with AG490 and SI-201, inhibitors of the JAK/STAT3 signaling pathway, BDMC was unable to exert cell-protective roles in SH-SY5Y cells treated with rotenone.

CONCLUSIONS: In conclusion, the results suggested that BDMC may exert a cell-protective role in SH-SY5Y cells in vitro via JAK2/STAT3 signaling, thus suggesting the possible application of BDMC for the treatment of neurodegenerative diseases related to JAK2/STAT3 signaling.
