GDF9 encodes growth differentiation factor 9 (GDF-9), an oocyte-secreted TGF-β superfamily ligand that signals primarily through BMP/TGF-β receptor complexes to activate SMAD2/3-dependent transcriptional programs. It is a key paracrine regulator of granulosa cell proliferation, cumulus expansion, and bidirectional oocyte–somatic cell communication that supports folliculogenesis and oocyte competence. GDF-9 activity intersects with extracellular matrix remodeling and differentiation pathways that coordinate ovarian follicle maturation and ovulation. Dysregulated GDF9 expression or function is associated with impaired follicle development and reproductive endocrine phenotypes, making it a relevant target for mechanistic studies in ovarian biology.
GDF-9 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the GDF9 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within GDF9. When directed to adjacent sites on opposite DNA strands, the two nickases generate offset single-strand nicks that together produce a staggered double-strand break, requiring coordinated on-target activity from both guides. The resulting DNA break is resolved by endogenous cellular repair pathways, most commonly through non-homologous end joining (NHEJ), leading to insertions or deletions that disrupt GDF9 function. By requiring dual sgRNA engagement at the target locus, the double nicking approach enhances editing specificity and provides a complementary CRISPR strategy for applications where additional control over targeting precision is desired.
To support efficient identification of edited cells, one plasmid encodes GFP for fluorescent visualization of transfected populations, while the companion plasmid carries a puromycin resistance gene for antibiotic selection. Together, these features support efficient enrichment of co-transfected populations and simplify the validation of GDF9-disrupted clones.
