TGFB1I1 and central nervous system cancer: To confirm the role of TGFB1I1 in EMT process, we performed correlational analyses in 310 samples with genome expression in CGGA database (5 NBTs, 126 grade II, 51 grade III and 128 grade IV gliomas) and obtained a cluster of the top 308 genes (354 probes, supplementary table 5) which were significantly positively correlated with TGFB1I1 expression (R>0.6, p<10−30).
