在活跃增殖的瑞士3 T3成纤维细胞中,原癌基因c-jun的表达在有丝分裂完成后立即在G1早期被最大程度地诱导。在2小时内,c-jun mRNA水平下降到约为最大值的30%的基础量。这一点在G1的其余部分都得到了保持。为了获得这种c-jun表达模式的功能意义,将c-jun特异性的反义寡聚体加入到活跃增殖或同步化的Swiss 3 T3细胞中,并测定其抑制DNA合成和分裂的能力。我们的研究结果表明,如果瑞士3 T3细胞与抗c-jun处理,而积极增长或在G1期完成有丝分裂后的任何时间,他们表现出降低的能力进入S期,随后分裂。这些结果表明,有丝分裂后G1期进展的调节依赖于原癌基因c-jun的表达和功能。
In actively proliferating Swiss 3T3 fibroblasts, expression of the protooncogene c-jun is maximally induced early in G1, immediately after completion of mitosis. Within 2 hours, c-jun mRNA levels drop to a basal amount that is approximately 30% of the maximum. This is maintained throughout the remainder of G1. To access the functional implications of this pattern of c-jun expression, antisense oligomers specific to c-jun were added to either actively proliferating or synchronized Swiss 3T3 cells, and their ability to inhibit DNA synthesis and division was determined. Our results show that if Swiss 3T3 cells are treated with anti-c-jun while actively growing or at any time during G1 after completion of mitosis, they exhibit a reduced ability to enter S-phase and subsequently divide. These results demonstrate that the regulation of G1 progression following mitosis depends on the expression and function of the protooncogene c-jun.
