dc.description.abstractTo investigate the neuroprotective activity of the aqueous extract of Sutherlandia frutescens (SF) against 1-methyl-4-phenylpyridinium (MPP+)-induced toxicity in SH-SY5Y neuroblastoma cells. Methods: SH-SY5Y neuroblastoma cells were divided into different treatment groups: untreated cells, cells treated with MPP+ alone (2 mM), cells pretreated with SF (20 μg) prior to MPP+ (2 mM) treatment and cells treated with SF (20 μg) alone. Twenty-four hours after treatment with MPP+, cell viability was assessed by MTT assay, and changes in cell morphology, intracellular reactive oxygen species (ROS) production, mitochondrial membrane potential (MMP) as well as caspases 3/7 and 9 activities were determined. Results: Treatment of SH-SY5Y cells with MPP+ alone significantly altered cellular morphology, increased ROS production (p = 0.005), induced a significant loss of MMP (p = 0.0011) and caused significant apoptotic cell death, via the activation of caspases 3/7 and 9 (p ≤ 0.0359). These effects were however significantly (p ≤ 0.0359) attenuated in cells pre-treated with the aqueous leaf extract of SF, indicating the possible neuroprotective activity of the SF extract.en_US
