Abstract:

The study was designed to investigate the effects of Src tyrosine protein kinase inhibitor(SAFA320) on transgenic Caenorhabditis elegans strainCL4176, along with its underlying mechanism. In the study, C. elegans CL4176 adminstrated with SAFA320 could reduce the deposition of Aβ oligomer to alleviate nematode paralysis, and decrease ROS production. Results of tissue Src kinase activity spectrophotometry analysis showed that SAFA320 could reduce the activities of Src in C. elegans. Meanwhile, the gene expression of skn-1 and its downstream target gene gst-4 were significantly increased, suggesting that compound inhibited Aβ toxicity may involve in SKN-1 signaling pathway in CL4176. In conclusion, SAFA320 is effective in alleviating Aβ toxicity and improving cognitive functions in C. elegans CL4176, and it is a potent candidate agent against Alzheimer’s Disease(AD).
