ETHNOPHARMACOLOGICAL RELEVANCE: The mushroom Inonotus hispidus is traditional Chinese medicine, which has been used to treat tumor illness for many years in China. However, the potential anti-tumor mechanisms of I. hispidus remain unclear.
OBJECTIVE: This study aimed to reveal the anti-tumor mechanism of I. hispidus petroleum ether extract (IPE) on H22 tumor-bearing mice from the point of view of metabonomics.
MATERIALS AND METHODS: The model of H22 tumor-bearing mice was constructed according to the histopathological data and biochemical parameters, while the serum metabolomics was analyzed by non-targeted ultra-high performance liquid chromatography and high-resolution mass spectrometry (UPLC-MS/MS) to study the potential anti-tumor mechanisms of IPE.
RESULTS: These results indicated that IPE has significant anti-tumor effect on H22 tumor-bearing mice and no obvious adverse reactions were observed. After the intervention of IPE, the biosynthesis of cortisol and corticosterone as the metabolics in the downstream of steroid biosynthesis pathway and the biosynthesis of succinate, fumarate and malate as the metabolics in the downstream of tricarboxylic acid cycle pathway were inhibited; but the metabolic pathways of the amino acids as tryptophan, lysine degradation, alanine, aspartate and glutamate and other amino acid were activated.
CONCLUSION: IPE has significant anti-tumor effect in H22 tumor-bearing mice, and the anti-tumor activity of IPE is main through the regulation of energy, amino acids, and steroid hormone biosynthesis pathways expression.
