RHBDF1 Knockout Cell Line (A549)

The choice depends on whether you are studying RHBDF1 (iRhom1)'s role in lung cancer EGFR ligand shedding or its emerging functions in NSCLC biology. The Knockout line is appropriate for asking whether iRhom1 is required for ADAM17-mediated shedding in lung cancer contexts — iRhom1 may be the dominant iRhom in lung epithelial cells in many tissue contexts. Overexpression is useful for studying iRhom1 in lung cancer progression and EGFR autocrine loops. For lung cancer research, the EDITGENE RHBDF1 Knockout in A-549 enables study of iRhom1's contribution to lung cancer EGFR ligand shedding in an NSCLC context. This product complements the parallel RHBDF1 Knockout in HEK293 and the RHBDF1 & RHBDF2 Double Knockout in A-549; the lung cancer context is preferred for disease-relevant studies. Rescue with wild-type or non-functional iRhom1 variants enables comprehensive structure-function studies.

Primary applications: • Lung cancer EGFR shedding: EGFR ligand release analysis in NSCLC context — iRhom1 may be the dominant iRhom in lung epithelial cells. • Tumor cell-intrinsic shedding: contribution of iRhom1-mediated shedding to autocrine signaling versus tumor-microenvironment-derived effects. • iRhom1 versus iRhom2 in lung cancer: side-by-side comparison with parallel RHBDF2 Knockout in A-549 reveals paralog-specific contributions. • Combined analysis: synergy with the RHBDF1 & RHBDF2 Double Knockout in A-549 for complete iRhom-ADAM17 disruption studies. EDITGENE recommends this A-549-based model for tumor cell-intrinsic iRhom1 functions in lung cancer; HEK293 parallel knockout is preferred for biochemistry.

Yes. iRhom1 rescue in A-549 is well-suited for lung cancer EGFR pathway research: • Construct design: use a codon-modified RHBDF1 sequence with a small C-terminal tag (FLAG, HA). Preserve the 7-transmembrane rhomboid family architecture. • Lung cancer-relevant rescue: assessment of iRhom1's contribution to lung cancer EGFR ligand shedding through wild-type or non-functional iRhom1 rescue. • Paralog comparison: side-by-side rescue analysis with parallel iRhom2 rescue (in RHBDF2-null A-549) reveals paralog-specific contributions in identical lung cancer background. • Functional readout: rescue should restore ADAM17 maturation, EGFR ligand shedding, and EGFR autocrine signaling phenotypes. A-549 transduces efficiently with lentivirus and supports stable rescue line generation.
