The suppression of the immune system creates a permissive environment for development and progression of cancer. One population of immunosuppressive cells that have become the focus of intense study is myeloid derived suppressor cells , immature myeloid cells able to induce immune-escape, angiogenesis, and tumor progression. Two different subpopulations have been identified and studied: granulocytic and monocytic myeloid derived suppressor cells with a different immunophenotype and immunosuppressive properties
Chronic myeloid leukemia (CML) is a myeloproliferative neoplasm companies with the BCR-ABL fusion gene encoded by the Philadelphia (Ph) chromosome. The BCR-ABL fusion protein(the formation of the chimeric gene BCR/ABL on chromosome 22 and a reciprocal ABL/BCR on chromosome 9,it has no expanded name) plays key role on CML leukemogenesis by activating its downstream signaling pathway of survival and proliferation. Imatinib, a targeted competitive inhibitor of a BCR-ABL tyrosine kinase, changed the clinical treatment and prognosis of CML. As its optimized generation, other tyrosine kinase inhibitors (TKIs), dasatinib and nilotinib have more potent anti-leukemic activity and less side-effect. However, acquired resistance to TKIs is one of the main obstacles to effective CML treatment and is involved in gene amplication of ABL tyrosine kinase point mutations. The outcomes of patients with these ABL tyrosine kinase point mutations have linked to worse prognosis and higher mortality generally. Metabolic adaptations are common in cancer cells, and cancer cells become more dependent on mitochondrial biogenesis. Tigecycline, as a broad-spectrum antibiotics, inhibits mitochondrial biogenesis as its an interesting "side-effect".In recent study,researchers indicated that tigecycline can eradicate cancer stem cells by targeting mitochondrial.Here, the investigators test tigecycline's anti-leukemic activity to chronic myeloid leukemia in vitro.
This is a efficacy and safety study of imatinib Mesylate Capsule as First line treatment in patients with chronic phase of Chronic Myeloid Leukemia.
