TGM2 and central nervous system cancer: We next compared the effects of LM11 versus TTGM 5826 on the viability of glioma cells, using two different cell lines that expressed varying levels of TG2, namely U87-MG cells (U87) which highly express TG2, and T98G cells that express lower levels of TG2 (Fig. 5c, Full gel image in Fig. S7b).
