Analysis on metabolites with small molecule of serum in bone marrow suppression model mice with metabolomics method

Bone marrow suppression is a common symptom in patients with malignant tumor after chemotherapy. Studying the changes of metabolites caused by bone marrow depression can provide insights for the diagnosis of bone marrow suppression disease and for the development of drug therapy. Male BalB/C mice were injected with cyclophosphamide to establish a bone marrow suppression model. Gas chromatography-mass spectrometry (GC-MS) with fingerprinting was used to analyze the normal and model mice blood metabolites. Principal component analysis and orthogonal to partial least squares discriminant analysis (OPLS-DA) on metabolomics for data multidimensional statistical analysis was also used. Compared to the normal group in terms of the metabolic profile of bone marrow suppression mice, there were 15 endogenous metabolites in mouse plasma, nine of which were statistically significantly different, including glucose-1-phosphate, 4-nitrophenol, acetanilide, cortisone, nicotinamide, loganin, caffeic acid, linoleic acid and oleic acid (P<0.05). These results indicate that metabolite can be used as an important marker in bone marrow suppression, which can help to reveal the pathogenesis of bone marrow suppression induced by chemotherapy and determine the disease development stage and the effectiveness of follow-up treatment.
