LPIN1 encodes lipin-1, a Mg2+-dependent phosphatidic acid phosphatase that catalyzes conversion of phosphatidic acid to diacylglycerol, a key step in glycerolipid and triacylglycerol biosynthesis. Beyond its enzymatic role, lipin-1 influences lipid droplet dynamics and coordinates transcriptional programs controlling fatty acid oxidation and mitochondrial metabolism through interactions with nuclear receptors and co-regulators. LPIN1 activity integrates nutrient and hormonal cues within adipocyte differentiation, hepatic lipid handling, and muscle energy homeostasis pathways. Dysregulation of LPIN1 has been linked to metabolic phenotypes and lipid storage abnormalities, and human variants are associated with susceptibility to lipid-related and muscle metabolic disorders.
Lipin-1 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous LPIN1 expression without altering the underlying DNA sequence.
Lipin-1 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the LPIN1 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 LPIN1 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous Lipin-1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native LPIN1 locus and enabling the study of Lipin-1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of Lipin-1 pathway restoration in tumor cells with silenced or reduced LPIN1 expression.
