SLC10A1 encodes the sodium/taurocholate cotransporting polypeptide (NTCP), a hepatocyte plasma membrane transporter that mediates sodium-dependent uptake of conjugated bile acids from portal blood. NTCP supports enterohepatic bile acid recirculation and influences bile acid–regulated signaling programs, including FXR- and TGR5-linked transcriptional control of lipid, glucose, and inflammatory pathways. Altered SLC10A1/NTCP activity is associated with disrupted bile acid homeostasis, cholestatic phenotypes, and broader metabolic dysregulation. Because NTCP also functions as an entry factor for hepatitis B and D viruses, it is frequently studied in hepatocyte biology, viral-host interactions, and transporter-mediated xenobiotic handling.
NTCP CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous SLC10A1 expression without altering the underlying DNA sequence.
NTCP CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the SLC10A1 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 SLC10A1 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous NTCP expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native SLC10A1 locus and enabling the study of NTCP-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of NTCP pathway restoration in tumor cells with silenced or reduced SLC10A1 expression.
