The helix-loop-helix transcription factor TWIST is dysregulated in myelodysplastic syndromes.


Patients with low-grade myelodysplastic syndromes (MDS) show high levels of tumor necrosis factor α (TNFα) and up-regulation of apoptosis in the marrow. In contrast, marrow cells in advanced MDS are typically resistant to TNFα-induced apoptosis but are rendered apoptosis-sensitive on coculture with stroma. The present studies show that CD34(+) marrow cells… (More)
