Differential Proteomic Analysis of AML Patients at Low and Intermediate Altitudes after Chemotherapy

Abstract

Chemotherapy is the primary treatment for patients with acute myeloid leukemia (AML). In addition to factors such as patient age, physical condition, and choice of medication, we have noticed that environmental factors such as altitude may also have a significant impact on post-chemotherapy bone marrow suppression in AML patients in clinical practice. The results indicate that there are differences in the proteomics of the two groups of patients during the bone marrow suppression period after chemotherapy. Differentially expressed proteins are primarily located in the cytoplasm, extracellular space, and nucleus, followed by mitochondria and membranes. These differentially expressed proteins mainly participate in biological processes such as cell and metabolism. For differential protein KEGG pathway enrichment analysis, it was found that metabolic pathways were mainly enriched in the metabolic category, while the PI3K-Akt signaling pathway, HIF-1 signaling pathway, NF-{kappa}B signaling pathway, and calcium signaling pathway were enriched in the signaling pathways.
