01General information

Description

KYSE180细胞系是一种源自原发肿瘤的人食管鳞状细胞癌(ESCC)模型。该细胞系被归类为中度分化型,并表现出一系列ESCC特有的遗传改变,包括NRF2(NFE2L2)信号通路的突变。 具体而言,KYSE180细胞携带NRF2 D77V突变,该突变导致NRF2过度活化——NRF2是一种参与氧化应激反应和肿瘤进展的转录因子。

KYSE180细胞被广泛用于研究食管鳞状细胞癌的分子机制,包括化疗耐药性和致癌信号传导。KYSE180细胞中NRF2活性的升高已被证实与化疗和放疗耐药性相关,因为NRF2能增强细胞的抗氧化防御能力和代谢适应能力。 近期研究已鉴定出嘧啶胺等能够抑制NRF2信号传导的化合物,从而降低KYSE180细胞的增殖能力和致瘤性。此类研究凸显了在NRF2高表达的癌症中靶向NRF2的治疗潜力。

此外,KYSE180细胞已被用于评估醛酮还原酶(AKR)家族酶(特别是AKR1C1和AKR1C2)在药物代谢和化学预防中的作用。 这些酶在KYSE180细胞中的表达上调,从而增强了该细胞系对乙基-3,4-二羟基苯甲酸酯(EDHB)等药物的敏感性。该化合物可诱导凋亡和自噬,表明该细胞系在探索食管鳞状细胞癌(ESCC)的药物反应及细胞应激机制方面具有实用价值。

Subculturing
去除粘附细胞上的旧培养基,用不含钙和镁的 PBS 冲洗。T25 烧瓶用 3-5 毫升 PBS,T75 烧瓶用 5-10 毫升。然后用 Accutase 完全覆盖细胞,T25 烧瓶用 1-2 毫升,T75 烧瓶用 2.5 毫升。让细胞在室温下孵育 8-10 分钟,使其分离。孵育后,用 10 毫升培养基轻轻混合细胞使其重悬,然后用 300xg 离心 3 分钟。弃去上清液,用新鲜培养基重悬细胞,并将其转移到已装有新鲜培养基的新烧瓶中。

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。
