[Progress of experimental study on myelodysplastic syndrome -- review].

The myelodysplastic syndrome (MDS) is an abnormal clonal proliferation disease resulting from disorder of hematopoietic stem cells/progenitor cells and is characterized by ineffective hematopoiesis and high risk of transforming into acute leukemia. The present experimental studies in gene, chromosome, cytokines and biochemical aspects may put the genetically models for clarifying the pathogenesis of MDS, help to early evaluation of disease prognosis and eventually develop the strategies of more effective prevention and treatment methods for MDS. In this article, the advances of chromosome, gene, cytokines and biochemical aspects in pathogenesis of MDS are summarized on basis of proceedings of ASH meeting in 2007 years.

[Possible mechanism underlying apoptotic induction effect of vitamin K2 on human MDS cell line MUTZ-1].

The study was aimed to investigate the possible mechanism of vitamin K(2) (VK(2)) on myelodysplastic syndrome (MDS) cell line MUTZ-1 in vitro. The flow cytometry was used to analyze apoptosis rate and the change of cell cycle. The expression of apoptosis-related genes bcl-2, survivin and bax were detected by reverse transcription-polymerase chain reaction (RT-PCR).
