Garidi-13 (GRD-13) is one of the most important Mongolian medicines with long history of clinical application in Inner Mongolia of China as well as the Republic of Mongolia [1-3]. Clinical application demonstrated that GRD-13 has remarkably high neuroprotective effect in stroke patients [4]. However, the mechanism of action of GRD-13 is unknown. Herein, we show that rat MCAO model treated with GRD-13 showed significantly improved neurorecovery compared to the non-treated control animals, demonstrated by reduced stroke lesion area and edema, higher neuron survival rate as well as reduced neurological impairment assessed by Bederson scaling. Analysis of transcriptome further elucidated that the mechanism of action of GRD-13 possibly mediated by up-regulating the expression of Igf2 gene in the ischemic area of MCAO model rats. These findings would provide theoretical guidance for the further development of GRD-13 and related Mongolian medicines.
