While these two new approved drugs offer an option for many patients with imatinib, dasatinib and nilotinibresistant CML, novel 6-Carboxy-X-rhodamine better strategies have to be developed. In contrast with bosutinib, our combined treatment with bortezomib and mitotic inhibitors is able to target Bcr-Abl with T315I mutation. Moreover, lower concentrations of each drug can be used in synergistic combinations, which may reduce toxicity. However, the toxicity of our regimens remains to be established. The potential of Bortezomib or Bortezomib-based combination therapies in hematological malignancies is also underscored by their ability to target tumor environment. Tumor microenvironment is a dominant force in inducing resistance to therapy in multiple malignancies. Tumor microenvironment plays a key role in leukemic stem cell maintenance and in modulating signal transduction and resistance in CML and AML. In conclusion, the combination of bortezomib and mitotic inhibitors such as paclitaxel, docetaxel, vincristine or BI 2536 is an 946387-07-1 effective strategy for targeting of both TKIs-resistant and sensitive Bcr-Abl-positive leukemic cells. These regimens are able to inhibit Bcr-Abl activity and its downstream signaling, and to activate caspase-dependent cell death. In addition, these regimens are able to overcome the resistance to imatinib, dasatinib and nilotinib, brought about by Bcr-Abl protein overexpression or Bcr-Abl mutations, making them attractive potential therapies for Bcr-Abl-positive leukemias such as CML, especially for those resistant to current treatments. The incidence of thyroid cancer has increased over the past three decades worldwide. Increased detection of small tumors accounts for half of the increase, although other etiologies for this increase remain to be determined. The most common pathologic types of thyroid cancer originate from follicular and parafollicular thyroid cells. Patients with well differentiated thyroid cancer usually have favorable prognosis. However, there is limited treatment for patients who develop metastatic and radioiodine-refractory thyroid cancer, which is often incurable. ATC is a rare and typically fatal malignancy, with a median sur
