TNFSF11 encodes RANKL, a TNF superfamily cytokine that functions as a key ligand for the receptor RANK (TNFRSF11A) to regulate osteoclast differentiation, activation, and survival. RANKL-driven signaling engages TRAF adaptors to activate NF-κB and MAPK cascades, coupling immune cues to bone remodeling and inflammatory responses. In addition to its roles in osteoimmunology, RANKL contributes to lymph node organogenesis and influences dendritic cell–T cell communication. Dysregulated RANKL/RANK/OPG axis activity is associated with pathological bone loss and remodeling phenotypes, and is frequently investigated in contexts of inflammation-associated skeletal changes and tumor–bone microenvironment interactions.
RANKL CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous TNFSF11 expression without altering the underlying DNA sequence.
RANKL CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the TNFSF11 locus in human cell lines. The system is built around a catalytically inactive Cas9 (dCas9) carrying two inactivating mutations (D10A and N863A) that eliminate nuclease activity while preserving DNA binding. This dCas9 is fused to VP64, a potent transcriptional activator, and is co-expressed with a blasticidin resistance gene for selection. The second plasmid encodes the MS2-p65-HSF1 fusion protein, a secondary activator complex that works in concert with dCas9-VP64, alongside a hygromycin resistance gene. The third plasmid encodes a target-specific 20 nt sgRNA fused to two MS2 RNA aptamers that recruit the MS2-p65-HSF1 complex to the activation site, accompanied by a puromycin resistance gene. The three plasmids are delivered at a 1:1:1 mass ratio for balanced expression of all system components.
Once assembled at the target locus, the SAM complex binds within approximately 200 bp upstream of the TNFSF11 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous RANKL expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native TNFSF11 locus and enabling the study of RANKL-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of RANKL pathway restoration in tumor cells with silenced or reduced TNFSF11 expression.
