Transcriptome Analysis of Protective Mechanism of Gastrodiae Rhizoma on Neurons of Parkinson Mice
Objective: To study on the therapeutic effect of Gastrodiae Rhizoma decoction on A53T α-synuclein transgenic Parkinson mice and its influence on the expression of apoptosis related pathways. Method: A53T α-synuclein transgenic mice with Parkinson disease were used as experimental subjects
and model group
Gastrodiae Rhizoma group
blank group and positive group(madopar group) were also set up.The pathological changes of substantia nigra neurons in mice were determined by genotype identification
hematoxylin-eosin(HE) staining and behavioural experiment to judge the success of the model establishment
the Illumina HiSeq 2500 platform sequencing technologies was used to detect differential expression of transcripts of all genes in Gastrodiae Rhizoma group.The genes related to Parkinson's protection and metabolic pathways were screened by functional annotation and enrichment analysis. Result: It could improve the substantia nigra neuron pathological changes in A53T α-synuclein transgenic Parkinson mice after treating Gastrodiae Rhizoma decoction
and transcriptome analysis showed that the mechanism mainly involved the inhibition or activation of proto oncogene of rat sarcoma(Ras)
p38 mitogen activated protein kinase(p38 MAPK) and Ca2+ related apoptosis pathways.Compared with the model group
the expression of dopamine third receptor(DRD3)
neuropeptide Y(NPY)
Ras protein specific guanine nucleotide releasing factor 1 (RASGRP1)
calcium/calmodulin-dependent 3'
5'-phosphodiesterase 1A(PDE1A) in Gastrodiae Rhizoma group were up-regulated
and apoptotic genes
such as proto oncogene of c-Fos
p38 MAPK and protein kinase 3 activated by human mitogen activated protein kinase (MAPKAPK3) were down-regulated. Conclusion: Gastrodiae Rhizoma decoction has a certain therapeutic effect on A53T α-synuclein transgenic Parkinson mice
its mechanism may be mainly related to the inhibition of many apoptotic related signaling pathways.
