AIM To investigate the role of the Notch1 signaling pathway in growth arrest of an esophageal carcinoma cell line (EC109) in vitro and the mechanism involved. METHODS An intracellular domain of Notch1 (ICN) was transfected into cultured EC109 cells by lipofectamine transfection. Subsequently, the proliferation of the transfected cells was measured by an(More)
OBJECTIVE At present there is no effective therapeutic approach for stage IV neuroblastoma. We report our experience with allogenic hematopoietic stem cell transplantation as a means of treating this disorder in one child. METHODS A 7-year-old boy with stage IV neuroblastoma received allogenetic hematopoietic stem cell transplantation. The donor was his(More)
This study was aimed to investigate the expression of FLT3 internal tandem duplication (FLT3-ITD) in pediatric patients with acute myeloid leukemia (AML) and to analyse the clinical features of patients with mutations and the relation of FLT3-ITD with multidrug resistance gene 1 (mdr1). RT-PCR was used to determine the expressions of FIT3-ITD and mdr1 gene(More)
Objective of this study was to establish a method for simultaneous detection of FLT3/ITD and NPM1 gene mutations in AML. A double PCR was firstly designed and optimized to amplify both exon 12 of NPM1 and exon 14-intron 14-exon 15 of FLT3, with the aim of detecting almost all reported mutations. After optimization, a touchdown PCR was chosen for the(More)
In order to investigate the mechanisms of phenylhexyl isothiocyanate (PHI) inhibiting the proliferation of multiple myeloma cell RPMI8226 in vitro, the RPMI8226 cells were co-cultured with PHI of various concentrations. The inhibition of proliferation was measured by MTT test and the cell apoptosis was assayed by DAPI staining. The changes of Notch1,(More)
This study was aimed to investigate the expression and clinical significance of forkhead box protein O3a (FoxO3a) in the patients with acute myeloid leukemia (AML). Western blot was used to detect the FoxO3a protein expression in bone marrow samples from 44 newly diagnosed AML patients and 5 healthy donors. Additionally, 14 patients' samples were(More)
The aim of study was to explore the expression of pituitary tumor-transforming gene (pttg) in acute myeloid leukemia (AML) and its relationship with the pathogenesis of AML, simultaneously to investigate the difference of the pttg expression among AML different subtypes. The expressions of pttg mRNA were quantitatively detected by real-time fluorescence(More)
