Human MLXIPL encodes carbohydrate-responsive element-binding protein (ChREBP), a glucose-sensing transcription factor that heterodimerizes with MLX and binds carbohydrate response elements to regulate genes involved in glycolysis, de novo lipogenesis, and triglyceride metabolism. ChREBP activity is modulated by nutrient and hormonal cues and integrates signaling from glucose metabolism with transcriptional programs in liver, adipose tissue, and pancreatic islets. Dysregulated MLXIPL/ChREBP signaling is linked to metabolic remodeling observed in insulin resistance, nonalcoholic fatty liver disease, and broader lipid homeostasis phenotypes. As a central node in nutrient-responsive transcription, ChREBP is widely studied for its effects on cellular energy balance, redox state, and metabolic flux.
ChREBP CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous MLXIPL expression without altering the underlying DNA sequence.
ChREBP CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the MLXIPL 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 MLXIPL transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous ChREBP expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native MLXIPL locus and enabling the study of ChREBP-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of ChREBP pathway restoration in tumor cells with silenced or reduced MLXIPL expression.
