HOXA9 encodes the homeobox transcription factor HoxA9, a key regulator of embryonic anterior–posterior patterning and hematopoietic lineage specification. In human cells, HoxA9 controls gene expression programs that govern stem/progenitor self-renewal, differentiation, and cell-cycle progression through HOX/MEIS regulatory networks and chromatin-associated transcriptional control. Dysregulated HOXA9 expression is strongly associated with aberrant myeloid differentiation and leukemogenic transcriptional states, making it a widely studied node in hematopoietic malignancy biology. HOXA9-dependent pathways are also used to model developmental gene regulation, epigenetic rewiring, and oncogenic cooperation in transcription factor–driven systems.
HoxA9 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous HOXA9 expression without altering the underlying DNA sequence.
HoxA9 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the HOXA9 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 HOXA9 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous HoxA9 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native HOXA9 locus and enabling the study of HoxA9-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of HoxA9 pathway restoration in tumor cells with silenced or reduced HOXA9 expression.
