HEK-Blue™ RANKL Cells signaling pathway
HEK-Blue™ RANKL cells were engineered from the human embryonic kidney HEK293 cell line to detect bioactive human and murine RANKL by monitoring the activation of the NF-κB and AP-1 pathways. In addition, these cells can be used for screening anti-RANKL antibodies, or inhibitors targeting the RANKL/RANK signaling pathway.
Receptor Activator of NF-κB Ligand (RANKL) exists as a soluble or transmembrane protein produced by osteoblasts and activated T cells [1]. RANKL binding to its receptor RANK and the subsequent signaling events play a pivotal role in bone remodeling and dendritic cell survival, thereby enhancing the induction of T cell responses [1].
Cell line description:
HEK-Blue™ RANKL cells were generated by stable transfection of human embryonic kidney HEK 293 cell line with the human gene for RANK (with all three functional TRAF-binding motifs) and an NF-κB/AP1-inducible SEAP (secreted embryonic alkaline phosphatase) reporter gene.
The binding of RANKL to its receptor on the surface of HEK-Blue™ RANKL cells triggers a signaling cascade leading to the activation of NF-κB/AP1, and the subsequent production of SEAP. For your convenience, InvivoGen provides QUANTI‑Blue™ Solution, an easy and rapid means to detect and quantify SEAP activity in the cell culture supernatant.
Features of HEK-Blue™ RANKL cells:
- Fully functional RANKL signaling pathway
- Readily assessable SEAP reporter activity
- Functionally tested
- Guaranteed mycoplasma-free
Applications of HEK-Blue™ RANKL cells:
- Detection of both human and mouse RANKL
- Screening of anti-RANKL antibodies
- Screening of inhibitors targeting RANKL/RANK signaling

Details
Receptor Activator of NF-κB Ligand (RANKL), also known as member 11 of the tumor necrosis factor (TNF) superfamily (TNFSF11) or TNF-related activation-induced cytokine (TRANCE), exists as a transmembrane or soluble protein produced by osteoblasts and activated T cells [1]. RANKL binds to its receptor RANK via an obligate trimer configuration [1, 2].
RANKL/RANK signaling plays a pivotal role in bone remodeling and dendritic cell survival, thereby enhancing the induction of T cell responses [1]. Upon RANKL binding, RANK trimers recruit TNF receptor-associated factor (TRAF) adaptor proteins, such as TRAF6, to TRAF-binding motifs within their cytoplasmic domains [1].
The TRAF6 signaling cascade results in the activation of NF-κB and AP-1 transcription factors. Multiple efforts have focused on the development of anti‑RANKL antibodies or small‑molecule inhibitors for blocking RANKL/RANK signaling to reduce osteoporosis, prevent skeletal-related events (SREs) from bone metastasis in cancer, or improve anti-tumor immunity [1-3].
