CYP19 Lentiviral Activation Particles (h) | sc-400604-LAC | 200 µl | $455.00 |
Human CYP19A1 encodes aromatase (CYP19), a cytochrome P450 enzyme in the endoplasmic reticulum that catalyzes the terminal step of estrogen biosynthesis by converting androgens into estrogens. Through control of local and systemic estradiol production, CYP19A1 modulates steroid hormone signaling networks that influence reproductive biology, adipose tissue function, bone homeostasis, and neuroendocrine regulation. Its activity integrates with steroidogenic pathways and feedback regulation along the hypothalamic–pituitary–gonadal axis, shaping transcriptional programs mediated by estrogen receptors. Dysregulated CYP19A1 expression or aromatase activity is implicated in hormone-dependent phenotypes and is frequently studied in contexts such as breast and endometrial tumor biology, polycystic ovary syndrome, and aromatase excess or deficiency syndromes.
CYP19 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 CYP19A1 upregulation across a broader range of human cell types.
CYP19 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 CYP19A1 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous CYP19 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native CYP19A1 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.
