TGFB1 and glioblastoma: HK2 is induced by TGF-β1 in human chondrocytes (C. Wang et al., 2018c), glioblastoma cells (Rodríguez-García et al., 2017), and in multiple mouse and human fibroblast cell lines (Yin et al., 2019), but is repressed in murine thymic Treg cells (Chen et al., 2020; Priyadharshini et al., 2018).
