英文摘要
Loss or reduction in function of tumor suppressor genes contributes to tumorigenesis. Here, by allelic DNA copy number analysis, we report homozygous deletion in glioblastoma multiformes (GBMs) at chromosome 13q21, where DACH1 gene is located. We found decreased cell proliferation by forced expression of DACH1. Exogenous bFGF, a target gene of DACH1, rescues spheroid-forming activity and tumorigenicity of the U87-DACH1-high cells, suggesting that loss of DACH1 increases the number of tumor-initiating cells through transcriptional repression of bFGF. These results illustrate that DACH1 is a novel tumor suppressor, which does not only suppress growth of tumor cells but also regulates bFGF-mediated tumor-initiating activity of glioma cells.
