Abstract:

OBJECTIVE: To unmask the underlying mechanisms of Yisui granule (益髓颗粒, YSG) for the treatment of Myelodysplastic syndromes (MDS).

METHODS: Our study used an SKM-1 mouse xenograft model of MDS to explore the anti-tumor potential of YSG and its safety, assess its effect on overall survival (OS), and evaluate whether its mechanism is associated with the demethylation of the secreted frizzled related protein 5 (sFRP5) gene and suppressing Wnt/β-catenin pathway. Bisulfite amplicon sequencing was applied to detect the level of methylation of the sFRP5 gene; western blotting, immunofluorescence staining, and real-time Polymerase Chain Reaction were performed to detect DNA methyltransferase 1 (DNMT1), sFRP5, and other Wnt/β-catenin pathway-related mRNA and protein expression.

RESULTS: The results showed that high-dosage YSG exerted an anti-tumor effect similar to that of decitabine, improved OS, and reduced long-term adverse effects in the long term. Mechanically, YSG reduced the expression of DNMT1 methyltransferase, decreased the methylation, and increased the expression of the Wnt/β-catenin pathway antagonist-sFRP5. Furthermore, components of the Wnt/β-catenin pathway, including Wnt3a, β-catenin, c-Myc, and cyclinD1, were down-regulated in response to YSG, suggesting that YSG could treat MDS by demethylating the sFRP5 gene and suppressing the Wnt/β-catenin pathway.

CONCLUSIONS: Our findings demonstrated that YSG could be used alone or in combination with decitabine to improve outcomes in the MDS animal model, providing an alternative solution for treating MDS.
