  • Abstract
  • Look Inside

Propentofylline (PPF) has been reported to stimu-late the synthesis/secretion of nerve growth factor (NGF) by cultured mouse astroglial cells. In the present study, we examined whether PPF stimulatesNGF synthesis in human glioma cell lines, the same as in mouse astroglial cells, and if so, whether NGF has a biological effect on glioma cells. After admini-stration of PPF into the glioma cell lines, we inves-tigated morphological changes and gene and protein expression of NGF, trkA, Fas and bcl-2 by using GFAP staining, Western blotting, and RT-PCR.
