肿瘤细胞经常对顺铂产生耐药性,这极大地损害了化疗的效果。识别耐药性的机制对于开发新的治疗方法非常重要。发现 ISG15 在许多人类癌症和癌细胞系中升高。在这里,我们发现与药物敏感的 A549 细胞相比,耐药 A549/DDP 细胞中 ISG15 和 ISG15 缀合系统的表达下调。 ISG15 的沉默显着提高了对顺铂的耐药性,表明 ISG15 在顺铂耐药性中发挥着重要作用。定量蛋白质组学鉴定了对照细胞和 ISG15 敲低细胞之间的 1296 个差异表达蛋白,表明 ISG15 沉默 p53 通路、粘附连接和核苷酸切除修复 (NER) 通路中上调的蛋白。我们还发现,ISG15 沉默通过稳定 p53 和增加 HnRNP K 表达来诱导细胞周期停滞,从而延长细胞修复顺铂损伤的 DNA 的时间。综上所述,我们证明 ISG15 下调激活 DNA 损伤/修复途径,增强肿瘤细胞对顺铂的耐药性。
Tumor cells frequently evolved resistance to cisplatin that greatly compromises the efficacy of chemotherapy. Identification of the mechanisms underlying drug resistance is important for developing new therapeutic approaches. ISG15 is found to be elevated in many human carcinomas and cancer cell lines. Here, we identified that the expressions of ISG15 and ISG15-conjugating system were downregulated in drug resistant A549/DDP cells compared to drug sensitive A549 cells. Silencing of ISG15 robustly elevated the resistance to cisplatin, suggesting ISG15 plays an important role in cisplatin resistance. Quantitative proteomics identified 1296 differentially expressed proteins between the control and ISG15 knockdown cells, showing that ISG15 silencing upregulated proteins in p53 pathway, adherens junction and nucleotide excision repair (NER) pathway. We also found that ISG15 silencing induced cell cycle arrest through stabilizing p53 and increasing HnRNP K expression, which allowed the prolonged time for cells to repair cisplatin-damaged DNA. Taken together, we proved that ISG15 downregulation activated the DNA damage/repair pathway to enhance cisplatin resistance in tumor cells.
