- Disease: Cancer
- Growth properties: Semi-adherent
- Model: Knock-Out
- Model description: NRAS KO using CRISPR/Cas9 to promote a stronger dependency on oncogenic G12C KRAS
- Crispr: Yes
- Conditional: No
- Description: Murine Lewis lung adenocarcinoma engineered cells represent a model for study of the effect of KRAS-G12C inhibitors on oncogenic cells. The cell line was established from 3LL cells by NRAS knocking out using CRISPR-Cas9 to promote a stronger dependency on oncogenic G12C KRAS. It was used in development of combination therapies to maximize the impact of G12C KRAS inhibitors in lung cancer
- Application: Development of combination therapies
- Production details: NRAS CRISPR/Cas knockout: To knock out NRAS, 3LL cells were transiently transfected with the pSpCas9(BB)-2A-GFP vector (PX458, Addgene) expressing a GFP expression cassette and with the gRNA 5’-gRNA-‘3 ACTGGACACAGCTGGACATG, PAM: ATG. GFP-positive cells were sorted using a MoFlo XDP sorter and single cell cloned manually. Clones were amplified and NRAS protein was quantified by Western blot
- Biosafety level: 1

Target Details
- Target: KRAS (V-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog); also known as ras; p21B; K-Ras; K-ras; Kras2; Ki-ras; Kras-2; K-Ras 2; c-K-ras; c-Ki-ras
- Target background: The KRAS gene is an oncogene that encodes a small GTPase transductor protein called KRAS. KRAS is involved in the regulation of cell division as a result of its ability to relay external signals to the cell nucleus. Activating mutations in the KRAS gene impair the ability of the KRAS protein to switch between active and inactive states, leading to cell transformation and increased resistance to chemotherapy and biological therapies targeting epidermal growth factor receptors [PMID: 20617134]
