Mouse Dmd encodes dystrophin, a large cytoskeletal protein that links F-actin to the dystrophin–glycoprotein complex at the sarcolemma, stabilizing myofiber membranes during contraction and organizing costameres. Dystrophin supports mechanotransduction and membrane integrity, influencing calcium handling, nitric oxide signaling, and muscle regeneration programs. Loss or reduction of dystrophin disrupts the dystrophin-associated protein complex, leading to sarcolemmal fragility, inflammation, and remodeling pathways that are widely used to model Duchenne/Becker muscular dystrophy biology in mouse systems. Dmd is therefore central to studies of skeletal and cardiac muscle homeostasis, stress responses, and gene regulation in striated muscle.
dystrophin Lentiviral Activation Particles (m) address this need by packaging the complete synergistic activation mediator (SAM) transcriptional activation system into transduction-ready, high-titer lentiviral particles, enabling efficient Dmd upregulation across a broader range of human cell types.
dystrophin Lentiviral Activation Particles (m) 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 Dmd transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous dystrophin expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native Dmd 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.
