To determine whether an absence of GPIHBP1 expression would influence the growth of glioma tumors, CT-2A glioma cells that had been stably transfected with a Gaussia luciferase reporter were injected into the brains of wild-type and Gpihbp1–/– mice (n = 11/group). The gene discussed is GPIHBP1; the disease is central nervous system cancer.
