TheST2gene, which is specifically induced by growth sti-mulation in fibroblasts, encodes interleukin-1 receptor-rela-tedproteins and iswidely expressed in hematopoietic, helper T, and various cancer cells. However, the physiological as well as pathological functions of the ST2 gene products are not yet fully understood. In this study, we analyzed the expression of theST2gene in human glioma cell lines and human brain tumor samples with real-time polymerase chain reactionmethod,
