LRRC4 and glioma: The ultrastructure of glioma cell Tet-on-LRRC4/NGL-2 underwent a significant change, the nucleo-cytoplasmic ratio lessened, the nuclear shape became regular, heterochromatin in nuclei decreased while euchromatin increased, the volume of nucleoli lessened, rough ER increased significantly, the Golgi apparatus was well-developed and Golgi vesicles increased and were regularly arranged, most mitochondria were oval and their crista grew in number and were regularly arranged, and finally polyribosomes reduced while free ribosomes increased [26].
