HCT116-Dual™ Cells

HCT116-Dual™ cells are adherent epithelial cells that have been derived from the human HCT116 colorectal carcinoma cell line by stable integration of two inducible reporter constructs.

HCT116-Dual™ cells  express a secreted embryonic alkaline phosphatase (SEAP) reporter gene under the control of the IL-12 p40 minimal promoter fused to five NF-κB and AP-­1 binding sites.

HCT116-Dual™ cells also express the Lucia luciferase gene, which encodes a secreted luciferase, under the control of an ISG54 minimal promoter in conjunction with five IFN-stimulated response elements.

As a result, HCT116-Dual™ cells allow to simultaneously study the NF-κB pathway, by assessing the activity of SEAP, and the interferon regulatory factor (IRF) pathway, by monitoring the activity of Lucia luciferase.
Both reporter proteins are readily measurable in the cell culture supernatant when using QUANTI-Blue™, a SEAP detection reagent, and QUANTI-Luc™, a Lucia luciferase detection reagent.

• 1 vial of HCT116-Dual™ cells (3-7 x 106 cells) in Freezing Medium
• 100 μl Zeocin™ (100 mg/ml)

HCT116-Dual™ cells express numerous pattern recognition receptors (PRRs), including the NOD-like receptors (NLRs) NOD1 and NOD2 [1, 2], the RIG-I-like receptor (RLR) RIG-I [3, 4], and the Toll-like receptors (TLRs) TLR3 and TLR5 [5] but not TLR2 or TLR4 [2].

Upon recognition of their cognate PAMPs, these receptors induce signaling pathways leading to the activation of the transcription factors NF-kB and/or IRF3/7. Stimulation of HCT116-Dual™ cells with the following PAMPs, Poly(I:C) (TLR3), flagellin (TLR5), Tri-DAP (NOD1), and MDP (NOD2), leads to the activation of NF-kB. Stimulation with RLR ligands, such as transfected poly(I:C) or poly(dA:dT), or the STING agonist, 2’3’-cGAMP, triggers the IRF pathway.

HCT116-Dual™ cells are resistant to the selectable markers blasticidin and Zeocin™.
