Exposure of mouse resident and thioglycollate-elicited peritoneal macrophages to IFN-gamma leads to a marked increase in the TNF-alpha (tumor necrosis factor/cachectin), IL-1 and u-PA (urokinase-type plasminogen activator) mRNA levels. Nuclear run-on experiments show that IFN-gamma acts by enhancing the transcription of these three genes. Transcription of these three genes is also rapidly and transiently induced by cycloheximide, an inhibitor of protein synthesis, indicating that they are under the control of short-lived repressors.
将小鼠驻留的和经巯基乙酸盐诱导的腹腔巨噬细胞暴露于γ干扰素下,会导致肿瘤坏死因子α(肿瘤坏死因子/恶病质素)、白细胞介素-1和尿激酶型纤溶酶原激活剂(u-PA)的mRNA水平显著升高。细胞核连续转录实验表明,γ干扰素通过增强这三个基因的转录起作用。这三个基因的转录也会被蛋白质合成抑制剂放线菌酮迅速且短暂地诱导,表明它们受短命阻遏物的控制。
