PIEZO1 encodes a mechanosensitive, nonselective cation channel that converts membrane tension and shear stress into Ca²⁺ influx, enabling rapid mechanotransduction in diverse cell types. PIEZO1 signaling shapes calcium-dependent processes including endothelial flow sensing, cytoskeletal remodeling, cell volume control, and downstream transcriptional responses linked to inflammation and tissue homeostasis. In erythrocytes and vascular cells, PIEZO1 activity influences ion balance and membrane stability, connecting it to pathways that regulate hydration status and mechanobiology. Dysregulated PIEZO1 function has been associated with heritable red blood cell disorders and lymphatic or vascular phenotypes, making it a key target for studying force-dependent signaling in human disease models.
PIEZO1 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 PIEZO1 upregulation across a broader range of human cell types.
PIEZO1 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 PIEZO1 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous PIEZO1 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native PIEZO1 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.
