换一批摘要Objective: To analyze the changes of gene expression in phenylbutyrate induced differentiation of glioma cells. Methods: The expression levels of 14000 genes in glioma cells before and after inducement with sodium phenyl- butyrate for 2 h or 6 days were evaluated by cDNA array technique and proved by multi-dot blotting. Results: expression of 98 genes in glioma cells showed changes after the inducement. Some genes involved in transcription and translation and some oncogenes are down-regulated, while some gene involved in differentiation or apoptosis are up-regulated. 18 unknown expression sequencing tag (EST) changed too. Conclusion: A gene expression profile associated with differentiation of glioma cells was established.
