Taurine upregulated gene 1 (TUG1) is a lncRNA upregulated by taurine treatment [54], and reportedly, TUG1 is downregulated in glioma tissues; this downregulation is associated with the inhibition of caspase 3/9 activation and the induction of Bcl2, which are considered to be responsible for indicators of poor prognosis in glioma patients [55]. This evidence concerns the gene BCL2 and central nervous system cancer.
