EGLN3 encodes prolyl hydroxylase domain-containing protein 3 (HIF PHD3), an oxygen-sensing dioxygenase that hydroxylates HIF-α subunits to promote VHL-dependent ubiquitination and proteasomal turnover under normoxic conditions. By tuning HIF stability, PHD3 regulates hypoxia-responsive transcriptional programs governing angiogenesis, glycolytic metabolism, erythropoiesis, and cell survival, and it is linked to feedback control within the cellular hypoxia pathway. EGLN3 activity is influenced by oxygen tension, iron, and 2-oxoglutarate availability, integrating metabolic state with transcriptional adaptation. Dysregulated EGLN3/HIF signaling has been associated with contexts including tumor hypoxia, ischemia-reperfusion biology, and inflammatory microenvironments, supporting mechanistic studies of oxygen-dependent signaling.
HIF PHD3 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 EGLN3 upregulation across a broader range of human cell types.
HIF PHD3 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 EGLN3 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous HIF PHD3 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native EGLN3 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.
