TREX1 Knockout IRF-Inducible Lucia luciferase reporter mouse macrophages

RAW-Lucia™ ISG-KO-TREX1 cells were generated from the RAW-Lucia™ ISG cell line, which is derived from the murine RAW 264.7 macrophage cell line, through the stable knockout of the TREX1 gene. TREX1 (also known as DNAse III) is a major cellular 3’5’ exonuclease that plays a crucial role in maintaining immune homeostasis.

RAW-Lucia™ ISG-KO-TREX1 and RAW-Lucia™ ISG cells express a secreted reporter gene, Lucia luciferase, under the control of the I-ISG54 promoter which is comprised of the IFN-inducible ISG54 promoter enhanced by a multimeric ISRE.

RAW-Lucia™ ISG-KO-TREX1 and RAW-Lucia™ ISG cells can be used to study the role of TREX1 by monitoring IRF-induced Lucia luciferase activity. The levels of IRF-induced Lucia in the cell culture supernatant can be easily monitored using QUANTI-Luc™, a Lucia luciferase detection reagent.

The response of RAW‑Lucia™ ISG-KO-TREX1 cells to murine type I interferons (IFNs) is unaffected by the knockout of the TREX1 gene. The TREX1 KO appears to have little to no effect on the response to the ligands tested (e.g. VACV70/LyoVec and  2'3'-cGAMP).

RAW-Lucia™ ISG-KO-TREX1 cells are resistant to Zeocin™.

Figures


Response of RAW-Lucia™ ISG-KO-TREX1 cells to various stimuli. RAW-Lucia™ ISG-KO-TREX1 and RAW-Lucia™ ISG cells (parental cell line) were incubated with VACV70/LyoVec™ (1 µg/ml), poly(dA:dT)/LyoVec™ (1 µg/ml), poly(I:C) HMW/LyoVec™ (1 µg/ml), 5'ppp-dsRNA/LyoVec™ (1 µg/ml), 2'3'-cGAMP (3 µg/ml) and c-di-AMP (3 µg/ml). Mouse IFN-α (1x104 U/ml) and IFN-β (1x104 U/ml) serve as positive controls. Non-induced cells (NI) have been included as a negative control. After a 24h incubation, IRF activation was determined by measuring the relative light units (RLUs) in a luminometer using QUANTI-Luc™, a Lucia luciferase detection reagent. The IRF induction of each ligand is expressed relative to that of mIFN-β at 1x104 U/ml (taken as 100%).
