Glycodelin plays an important role in normal and abnormal reproductive growth. The in vitro properties of glycodelin have been studied in K562 cells. The role of glycodelin in vivo in the peripheral circulation has not been determined.
To determine if circulating leukocytes in normal subjects express the glycodelin gene, with a view to understanding its contribution to various disease processes.
RT-PCR analysis of mononuclear cells isolated from the blood of healthy volunteers was used to show glycodelin mRNA expression. Immunocytostaining was performed using anti-glycodelin antibody.
PCR analysis illustrated the expression of the glycodelin gene in peripheral mononuclear cells. Glycodelin protein in these cells was confirmed with immunostaining.
The presence of glycodelin in peripheral white blood cells was demonstrated. The ability of glycodelin to stimulate angiogenesis and act as an immunosuppressive agent could be an indicator of the role of peripheral leukocytes in various disease states.
糖蛋白在正常和异常生殖生长中起重要作用。已在K562细胞中研究了糖蛋白的体外特性。糖蛋白在体内外周循环中的作用尚未确定。
确定正常受试者循环白细胞是否表达糖蛋白基因,以了解其对各种疾病过程的作用。
采用逆转录聚合酶链反应(RT-PCR)分析从健康志愿者血液中分离的单核细胞,以显示糖蛋白信使核糖核酸(mRNA)的表达。使用抗糖蛋白抗体进行免疫细胞化学染色。
聚合酶链反应(PCR)分析表明外周单核细胞中存在糖蛋白基因的表达。通过免疫染色证实了这些细胞中存在糖蛋白。
已证实在外周白细胞中存在糖蛋白。糖蛋白刺激血管生成和作为免疫抑制剂的能力可能表明外周白细胞在各种疾病状态中的作用。
