ROMO1 and glioblastoma: We found that the clodronate liposomes significantly inhibited the in-vivo growth of GL261 cells (p<0.05 at Day 15 or 17 after injection, Figure 2B) and prolonged the survival curve of the mice transplanted with Romo1-overexpressed bone marrow cells (p<0.05, Figure 2C), indicating that the overexpression of Romo1 in bone marrow cells, mainly in the macrophages, promoted the progression of glioblastoma.
