Pharmacological mechanism of mylabris in the treatment of leukemia based on bioinformatics and systematic pharmacology

Abstract

Leukemia is a common blood cancer, whose treatment usually necessitates chemo/radiotherapy and bone marrow transplant. Hence, safer and more effective options are urgently needed. Mylabris, the dried body of blister beetles, has been used extensively in traditional Chinese medicine. This study applied bioinformatics and systematic pharmacology to investigate the mechanism of action of mylabris in the treatment of leukemia. Five effective components and 35 corresponding target proteins were identified by screening the TCMSP database; whereas 776 genes related to leukemia were selected using OMIM, GeneCards, and the Therapeutic Target Database. Eight genes common to mylabris and leukemia were identified. Protein-protein interaction network analysis and a component-target-pathway diagram identified TP53 and PTEN as key gene targets of mylabris in the treatment of leukemia. GO enrichment analysis pointed to DNA damage and cell cycle disorder caused by p53 signaling as the most significant processes; whereas KEGG enrichment pointed to the p53 signaling pathway. In summary, mylabris may exert a therapeutic effect on leukemia by triggering DNA damage, inducing apoptosis, as well as inhibiting the growth and proliferation of tumor cells through the regulation of TP53 and PTEN. These findings provide a mechanistic rationale for the treatment of leukemia with traditional Chinese medicine.

Danggui Jixueteng decoction for the treatment of myelosuppression after chemotherapy: A combined metabolomics and network pharmacology analysis

“…The lack of selectivity in most cancer chemotherapy drugs and their primary side effect of inhibiting bone marrow hematopoietic stem cells results in MAC [ 25 ]. In this study, cyclophosphamide, commonly used in clinical settings, was employed to construct a MAC animal model.…”

Integrated bioinformatics analysis and network pharmacology to explore the potential mechanism of Patrinia heterophylla Bunge against acute promyelocytic leukemia

“…Recent advances in clinical research have shed more light on the potential of Chinese herbal medicines and their extracts for the treatment of leukemia. [ 39 ] Pharmacological studies have revealed that PHEB is widely used in clinical settings for the treatment of leukemia. [ 40 ] PHEB contains compounds that inhibit the growth of tumor cells in APL, a rare but highly curable form of leukemia.…”

Downregulation of REST in the cochlea contributes to age-related hearing loss via the p53 apoptosis pathway

“…This was further confirmed by the elevated p53 expression seen in the cochlea of Rest cKO mice. The endogenous p53 pathway, induced by stresses such as acute DNA damage, plays a critical role in apoptosis, cell growth and senescence [ 35 – 37 ]. p53 induces cell apoptosis through different methods, inducing the self-cleavage and activation of downstream caspase-3 [ 38 ].…”
