KRAS Resistance Cancer Cell Line Screening

KRAS Resistance Modeling

Acquired resistance remains a central challenge for KRAS-directed drug discovery. ICE Bioscience provides drug-resistant cancer cell models spanning KRAS G12C, KRAS G12D, and pan-RAS inhibitor programs across pancreatic, colorectal, and lung cancer backgrounds.

Generated through in vitro drug-induced resistance selection, these models support resistance-focused pharmacology studies, comparative response profiling, and mechanism-of-action investigations using genomic and transcriptomic analysis.

Service Capabilities
A connected framework for KRAS resistance studies
01 · Model Selection

Select resistant models by cancer indication, inhibitor, and KRAS target class.

02 · Comparative Pharmacology

Compare parental and resistant models to characterize changes in compound response.

03 · MOA Investigation

Combine whole-exome sequencing and RNA-seq to investigate candidate resistance mechanisms.

Validated Model Portfolio
KRAS inhibitor-resistant cancer cell lines

The current portfolio includes 13 resistant models generated by in vitro drug-induced resistance selection. Additional models are continually being developed and added to the portfolio.
