TLX1 (Hox11) is a homeobox transcription factor that regulates embryonic patterning and lineage specification, with prominent roles in hematopoietic differentiation programs. By binding DNA at HOX response elements, Hox11 modulates transcriptional networks that intersect with developmental signaling and chromatin remodeling to control proliferation and cell fate decisions. Dysregulated TLX1 expression is linked to altered developmental gene expression states and has been associated with T-cell acute lymphoblastic leukemia, supporting its use as a node for studying oncogenic transcriptional rewiring. In human cell models, TLX1 serves as a tractable regulator for investigating HOX-driven gene regulatory circuits and context-dependent differentiation phenotypes.
Hox11 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous TLX1 expression without altering the underlying DNA sequence.
Hox11 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the TLX1 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 TLX1 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous Hox11 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native TLX1 locus and enabling the study of Hox11-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of Hox11 pathway restoration in tumor cells with silenced or reduced TLX1 expression.
