Drug resistance is a challenge in treatment of acute leukemia. To investigate novel protein changes involved in resistance, protein expression profiles between leukemia cell line HL-60 and adriamycin-resistant HL-60 (HL-60/ADR) were compared based on a proteomic approach-2D-DIGE followed by MALDI-TOF/MS. 13 protein spots were identified as up-regulated and(More)
Despite tremendous advances in the targeted therapy for various types of hematological malignancies with successful improvements in the survival rates, emerging resistance issues are startlingly high and novel therapeutic strategies are urgently needed. In addition, chemoprevention is currently becoming an elusive goal. Plant-derived natural products have(More)
BACKGROUND Baicalin, a flavone present in Scutellaria baicalensis Georgi, inhibits the growth of human leukemia and myeloma cells through induction of apoptosis. METHODS The present study was undertaken to ascertain whether cultured Burkitt lymphoma cells undergo apoptosis when treated with baicalin. Growth rates were measured using MTT and colony(More)
This study is to investigate the effect of emodin on inducing human myeloid leukemia cell line HL-60 apoptosis and the role of Akt signal pathway in the apoptosis. HL-60 cells were exposed to various dosages of emodin. MTT assay was used to detect HL-60 cell proliferation. Distribution of HL-60 cells in cell cycle was analyzed by flow cytometry and cell(More)
The study was aimed to investigate the effects of emodin on proliferation inhibition and apoptosis induction in human chronic myeloid leukemia cell line K562 cells, and to explore the role of P210 protein and activation of caspase 3 in these processes. K562 cells were exposed to emodin at different doses. The proliferation inhibition was detected by MTT(More)
The aim of study was to investigate the effect of a traditional Chinese medicine, emodin, on proliferation and apoptosis in T lymphocytic leukemic cell line Jurkat and its mechanisms. Cell proliferation inhibition was detected by MTT assay. Cell apoptosis was measured by DNA ladder and terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling(More)
OBJECTIVE To investigate the effects of emodin on apoptosis induction and proliferation inhibition in human apoptosis and on c-myc protein and mRNA expression in human myeloid leukemia cell line HL-60 cells. METHODS HL-60 cells were exposed to emodin at different dosages. Growth inhibition was detected by MTT assay and colony formation assay, and cell(More)
AIM Invasive fungal infections pose a severe health threat to patients. Despite recent advances in drug development, treatment of recurrent fungal infections remains difficult. Posaconazole is a broad-spectrum triazole antifungal drug available for oral administration. Although initial studies have described its use in treating various fungal infections,(More)
BACKGROUND Invasive fungal infection (IFI) is common in neutropenic patients with acute myelogenous leukemia (AML) or myelodysplastic syndrome (MDS). Posaconazole is a broad-spectrum triazole antifungal drug with efficacy in prevention of IFI; however, it has not been previously studied as prophylaxis in a Chinese population. METHODS This multicenter,(More)
Near haploidy (23-29 chromosomes) is a numerical cytogenetic aberration in childhood acute lymphoblastic leukemia (ALL) associated with particularly poor outcome. In contrast, high hyperdiploidy (51-67 chromosomes) has a favorable prognosis. Correct classification and appropriate risk stratification of near haploidy is frequently hampered by the presence of(More)
