OBJECTIVE To explore the effect of anti-CD44 monoclonal antibody A3D8 on expression of transcription factor AP-1 in acute myeloid leukemia cells. METHODS After acute leukemia cell line HL-60 was treated by different concentrations of A3D8, the proliferation and cell cycle were detected by MTT and FCM respectively. The expressions of c-JUN and c-FOS at(More)
There is no gold diagnostic standard for BCR-ABL fusion gene negative chronic myeloproliterative neoplasm(cMPN). The following detection methods such as comprehensive bone marrow cell morphology, bone marrow pathology, genetic mutation, flow cytometry and immunohistochemical are needed to diagnose the BCR-ABL fusion gene positive cMPN. The JAK2 mutation can(More)
Ginsenoside Rg3 (Rg3) is one of the primary constituents isolated from ginseng, and has been found to exhibit cytotoxic effects against cancer cells. The present study aimed to investigate the effects of Rg3 on human multiple myeloma cell proliferation and apoptosis, and to examine its underlying molecular mechanisms. Cell viability was detected using a(More)
This study was aimed to explore the killing effect of PBMNC induced by IL-23 alone or combined with IL-2 on K562 cells and its mechanism. The PBMNC were induced in vitro by IL-23 (50 ng/ml) alone or IL-23 combined with IL-2 (100 U/ml) for 72 h, and then were co-cultured with leukemia cell line K562. The CCK-8 method was used to detect the effect of PBMNC(More)
Hyperhomocysteinemia (HH) is a factor that predisposes individuals to thrombosis, and the C677T mutation in the 5,10-methylenetetrahydrofolate reductase (MTHFR) is known to give increased plasma homocysteine. However, little is known about their roles in Budd-Chiari syndrome (BCS). This study evaluated the roles of HH and the MTHFR C677T mutation in(More)
The hematopoietic cell phosphatase (HCP or SHP-1), the SH2 domain contain protein tyrosine phosphatase, is a crucial negative regulator in the process of hematopoietic cell development, proliferation and receptor-mediated mitogenic signaling pathways, and its mutation is responsible for the over-expansion and inappropriate activation of myelomonocytic(More)
The SH2 domain containing inositol 5'-phosphatase (SHIP) was initially described as a 145 kD protein phosphorylated on tyrosines upon growth factor and cytokine stimulation. SHIP is predominately expressed in hematopoietic cells, and is a crucial negative regulator in the development of hematopoietic cells. To evaluate the role of the SHIP gene in human(More)
Recently, a mitochondrial ceramidase has been identified and cloned, whose mitochondrial localization strongly suggests the existence of an unexpected mitochondrial pathway of ceramide metabolism that may play a key role in mitochondrial functions, especially in the regulation of apoptosis. To explore the biological effect of mitochondrial ceramidase on(More)
OBJECTIVE To investigate the effect of Panax notoginseng saponin (PNS) on procoagulant activity (PCA) and differentiation induction in NB4 cells. METHODS After NB4 cells were treated with PNS, the recalcification time, PCA and TF-mRNA expression in NB4 cells were tested by RT-PCR. The inhibitory effect of PNS on NB4 cell proliferation was analysed by MTT(More)
We explored the expression of phosphatase and tensin homolog deleted on chromosome 10 (PTEN) and focal adhesion kinase (FAK) mRNA and protein, and analyzed the relationship between expression levels and clinical staging and extramedullary infiltration in patients with multiple myeloma (MM). The expression levels of mRNA and protein were measured by(More)
