OBJECTIVE To investigate the relationship between bortezomib resistance and mutations in the proteasome beta5 subunit (PSMB5) gene. MATERIALS AND METHODS Various bortezomib-resistant lymphoblastic lymphoma/leukemia lines were established by repeated cycles of bortezomib selection. Mutations were detected by sequencing the complementary DNA of the PSMB5(More)
BACKGROUND In acute myeloid leukemia (AML), the leukemia initiating cells (LICs) or leukemia stem cells (LSCs) is found within the CD34+CD38- cell compartment. The LICs subpopulation survives chemotherapy and is most probable the cause of minimal residual disease (MRD), which in turn is thought to cause relapse. The aim of this study was to determine the(More)
OBJECTIVES To explore the combination therapy of all-trans retinoic acid (ATRA) and arsenic trioxide (ATO, As2O3) on acute promyelocytic leukemia (APL). METHODS A meta-analysis of six studies was performed. Among 415 included cases, 165 cases were in the ATRA + ATO group, 129 cases in the ATRA-alone group, and 121 cases in the ATO-alone group. The(More)
OBJECTIVE To investigate the patients' characteristics and efficacy of prognosis evaluation by International Prognosis Scoring System (IPSS) and Revised International Prognosis Scoring System (IPSS-R) in patients with myelodysplastic syndrome (MDS). METHODS Prognostic value of IPSS and IPSS-R was evaluated on clinical data from 159 MDS patients, according(More)
The aim of the present study was to evaluate the effectiveness of bortezomib combined with epirubicin, dexamethasone, and thalidomide (BADT) for the treatment of multiple myeloma (MM). The BADT regimen consisted of a maximum of eight 4-week cycles of: intravenous bortezomib (1.0 mg/m(2)) and intravenous epirubicin (12 mg/m(2)) on days 1, 4, 8, and 11;(More)
High expression of proviral integration site for Moloney murine leukemia virus-1 (PIM-1), a serine/threonine kinase, is associated with many cancers. The main purpose of this study were to investigate that the correlation between PIM-1 mRNA levels and clinicopathologic features and its clinical significance in acute myeloid leukemia (AML). qRT-PCR was(More)
Acute myeloid leukemia (AML) is generally regarded as a disorder of stem cells, known as leukemic initiating cells (LICs), which initiate the disease and contribute to relapses. Although the phenotype of these cells remains unclear in most patients, they are enriched within the CD34+CD38− population. In core-binding factor (CBF) AML, the cytogenetic(More)
BACKGROUND Hypocellular acute myeloid leukemia (Hypo-AML) is a rare disease entity. Studies investigating the biological characteristics of hypo-AML have been largely lacking. We examined the clinical and biological characteristics, as well as treatment outcomes of hypo-AML in our institutes over a seven years period. DESIGN AND METHODS We retrospectively(More)
The pleiotropic cytokine interleukin (IL)-10 is best characterized by its ability to downregulate inflammation and promote peripheral tolerance. On the other hand, IL-10 was also found to maintain the effector response of CD8+ T cells and promote the expansion of tumor-resident CD8+ T cells. In diffuse large B cell lymphoma (DLBCL), the role of IL-10 has(More)
