SIRT1 Lentiviral Activation Particles (h) | sc-400085-LAC | 200 µl | $455.00 |
SIRT1 encodes sirtuin 1, an NAD⁺-dependent protein deacetylase that coordinates cellular responses to nutrient status, oxidative stress, and DNA damage. By deacetylating substrates such as p53, FOXO transcription factors, NF-κB, and PGC-1α, SIRT1 modulates chromatin accessibility, mitochondrial biogenesis, autophagy, and inflammatory signaling across pathways linked to metabolic homeostasis. SIRT1 activity intersects with AMPK–mTOR signaling and circadian regulation, shaping transcriptional programs that influence cell survival and differentiation. Dysregulated SIRT1 expression or activity has been associated with aging-related biology and with mechanisms relevant to cancer, neurodegeneration, and metabolic disorders, supporting its frequent use as a node for pathway-level studies.
SIRT1 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 SIRT1 upregulation across a broader range of human cell types.
SIRT1 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 SIRT1 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous SIRT1 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native SIRT1 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.
