αENaC Lentiviral Activation Particles (h) | sc-401123-LAC | 200 µl | $455.00 |
SCNN1A encodes the human epithelial sodium channel alpha subunit (αENaC), a pore-forming component of the amiloride-sensitive ENaC complex that mediates electrogenic Na⁺ entry across apical membranes in epithelial tissues. By controlling sodium absorption and coupling to osmotic water movement, αENaC supports airway surface liquid homeostasis, renal tubular sodium reabsorption, and epithelial volume regulation. ENaC activity is tuned by proteolytic processing, ubiquitin-dependent trafficking via NEDD4L, and hormonal signaling pathways including aldosterone-regulated SGK1, linking SCNN1A to ion transport and epithelial barrier physiology. Dysregulation of ENaC-mediated sodium handling is associated with disorders of salt and fluid balance and has been studied in the context of airway hydration phenotypes and renal electrolyte abnormalities.
αENaC Lentiviral Activation Particles (h) address this need by packaging the complete synergistic activation mediator (SAM) transcriptional activation system into transduction-ready, high-titer lentiviral particles, enabling efficient SCNN1A upregulation across a broader range of human cell types.
αENaC Lentiviral Activation Particles (h) deliver all functional components of the synergistic activation mediator (SAM) system via lentiviral transduction. The system comprises three particle preparations co-transduced into target cells: one encoding catalytically inactive dCas9 (D10A and N863A mutations) fused to the VP64 transactivation domain with a blasticidin resistance gene; one encoding the MS2-p65-HSF1 fusion protein with a hygromycin resistance gene; and one encoding a target-specific 20 nt sgRNA fused to two MS2 RNA aptamers with a puromycin resistance gene. Following lentiviral transduction and genomic integration of the expression cassettes, the SAM components are stably expressed and assemble at the target locus within the proximal promoter region upstream of the SCNN1A transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous αENaC expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native SCNN1A genomic locus and regulatory architecture.
The lentiviral format offers several practical advantages: stable genomic integration supports heritable activation across cell divisions; high-titer particle preparations eliminate the need for in-house viral production; and compatibility with primary, non-dividing, and transfection-resistant cell types expands experimental accessibility. Successful transduction can be confirmed and enriched through triple antibiotic selection using puromycin, hygromycin, and blasticidin.
