摘要

ATM、ATR和DNA- pk对于DNA损伤反应(DDR)和序列修复至关重要,从而导致基因组的稳定性。在本研究中,我们发现在THP1分化过程中,PMA显著诱导了这些蛋白的表达,而转录本的水平没有变化。此外,这些蛋白活性的抑制剂可抑制pma诱导的THP1细胞形态学改变。我们的研究结果表明这些DDR蛋白在细胞分化中的潜在作用。

Roles of DNA Damage Response Proteins in Mitogen-Induced Thp-1 Differentiation into Macrophage.

ATM, ATR and DNA-PK are critical for DNA damage response (DDR) and sequential repair, leading to genomic stability. In this study, we found the expression of these proteins is markedly induced by PMA during THP1 differentiation without the change in the level of transcripts. Also, inhibitors of these protein activity suppressed PMA-induced morphological change of THP1 cells. Our results suggest the potential roles of these DDR proteins in cellular differentiation.
