 note = {application/pdf, The effects of specific antibodies against growth factors and receptors on deoxyribonucleic acid (DNA) synthesis in two established human glioma cell lines, A172 and TM-1, were examined. Anti-platelet-derived growth factor (PDGF), anti-basic fibroblast growth factor (bFGF), and anti-epidermal growth factor receptor (EGF-R) antibodies inhibited thymidine incorporation by both cell lines in serum-free medium. Antibody specific to transforming growth factor-α only slightly suppressed DNA synthesis by both cell lines. Although the antiproliferative effects of anti-PDGF and anti-bFGF antibodies decreased in serum-supplemented medium, the effect of anti-EGF-R antibody was little changed. The combination of anti-PDGF, anti-bFGF, and anti-EGF-R antibodies significantly inhibited thymidine incorporation by the two cell lines even in serum-supplemented medium. This preliminary study suggests that simultaneous blockade of multiple autocrine loops may provide a new approach to the treatment of human malignant gliomas.
 成長因子と成長因子受容体に対する特異的抗体を用いて、ヒト培養グリオーマ細胞2株(A172, TM-1)の増殖抑制作用を検討した。抗PDGF、抗bFGF、抗EGF-Rは、単独で両グリオーマ細胞の無血清培地中におけるDNA合成を抑制した。これら抗体のDNA合成抑制作用は、前2者では血清添加培地中では減弱したが、抗EGF-Rの作用は変わらなかった。抗TGF-αのDNA合成抑制作用は弱く、血清添加培地中ではその作用は認められなかった。抗PDGF、抗bFGF、抗EGF-Rの3抗体を同時に作用させると両細胞のDNA合成は、血清添加培地中においても著しく抑制された。複数のオートクリンループを遮断することは、培養グリオーマ細胞の増殖抑制には有意義な手段であると考えられた。, Article},
