01General information

Description

NCI-H69AR 是母本小细胞肺癌(SCLC)细胞系 NCI-H69 的耐多药衍生物。它是在多柔比星等化疗药物浓度不断增加的情况下经过不断筛选而培育出来的。因此,NCI-H69AR 是研究 SCLC 获得性耐药机制的关键模型系统。该细胞系保留了其亲本细胞系的许多形态和生化特征,但对多种细胞毒性药物表现出极强的耐药性,因此特别适合研究外排介导的耐药途径。

NCI-H69AR 的主要耐药机制涉及 MDR1 基因编码的多药耐药蛋白 P-糖蛋白(P-gp)的过表达。P-gp 是一种 ATP 依赖性外排泵,可减少细胞内的药物蓄积,尤其是对蒽环类、长春花生物碱和表鬼臼毒素的蓄积。此外,NCI-H69AR 还表现出膜相关蛋白(包括附件蛋白 II)表达的改变,这可能与钙信号转导和囊泡贩运过程的变化有关--这些过程与耐药性和细胞应激反应有关。这些表型的改变使 NCI-H69AR 成为一个宝贵的模型,可用于确定耐药性的调节剂,以及评估针对外排机制或完全绕过耐药性途径的药物的疗效。

NCI-H69AR 还被用于与其亲本品系的比较研究,以确定基因和蛋白质表达的变化、药物敏感性特征以及对药物抑制剂的反应。这种比较框架有助于阐明癌症耐药性的演变,并有助于设计旨在使耐药性肿瘤重新敏感的综合疗法。该品系通常在补充胎牛血清的 RPMI-1640 培养基中培养,并在标准大气条件下保存。它的稳健性和表征良好的耐药性表型确保了它在肺癌耐药性临床前研究中的地位。

Thawing and culturing
  1. Confirm that the vial remains deeply frozen upon delivery, as cells are shipped on dry ice to maintain optimal temperatures during transit.

  2. Upon receipt, either store the cryovial immediately at temperatures below -150°C to ensure the preservation of cellular integrity, or proceed to step 3 if immediate culturing is required.

  3. For immediate culturing, swiftly thaw the vial by immersing it in a 37°C water bath with clean water and an antimicrobial agent, agitating gently for 40-60 seconds until a small ice clump remains.

  4. Perform all subsequent steps under sterile conditions in a flow hood, disinfecting the cryovial with 70% ethanol before opening.

  5. Carefully open the disinfected vial and transfer the cell suspension into a 15 ml centrifuge tube containing 8 ml of room-temperature culture medium, mixing gently.

  6. Centrifuge the mixture at 300 x g for 3 minutes to separate the cells and carefully discard the supernatant containing residual freezing medium.

  7. Gently resuspend the cell pellet in 10 ml of fresh culture medium. For adherent cells, divide the suspension between two T25 culture flasks; for suspension cultures, transfer all the medium into one T25 flask to promote effective cell interaction and growth.

  8. Adhere to established subculture protocols for continued growth and maintenance of the cell line, ensuring reliable experimental outcomes.

07Quality control and cryopreservation

Sterility

使用基于 PCR 的检测方法和基于发光的支原体检测方法排除支原体污染。

为确保没有细菌、真菌或酵母菌污染,每天都要对细胞培养物进行目视检查。

Freeze medium
我们使用完全生长培养基(包括 FBS)+10% DMSO 或 CM-1(Cytion 商品目录编号 800100)作为冷冻保存培养基,以获得足够的解冻后存活率,CM-1(Cytion 商品目录编号 800100)含有优化的渗透保护剂和代谢稳定剂,可提高恢复能力并减少冷冻引起的应激。
Storage conditions

如需长期保存,可将样品瓶放入气相液氮中,温度约为 -150 至 -196 ℃。在-80 °C下保存只能作为转入液氮前的短暂过渡。

Shipping conditions

冷冻保存的细胞系用干冰装运,并用经过验证的隔热包装和足够的制冷剂在整个运输过程中保持约 -78 °C 的温度。收到货后,应立即检查容器,并立即将小瓶转移到适当的储藏室。
