HSD17B3 encodes human 17β-HSD3, a microsomal oxidoreductase that catalyzes the NADPH-dependent conversion of androstenedione to testosterone, a key step in androgen biosynthesis. This enzyme functions within steroid hormone metabolic networks that shape androgen receptor signaling and downstream transcriptional programs affecting sexual development and reproductive physiology. HSD17B3 activity contributes to tissue-specific androgen availability through intracrine steroid metabolism and intersects with broader pathways governing steroidogenic flux and redox balance. Altered HSD17B3 function or expression is studied in the context of disorders of sex development and androgen-dependent endocrine phenotypes, as well as mechanisms of steroid metabolism in gonadal and peripheral tissues.
17β-HSD3 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the HSD17B3 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within HSD17B3. 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 HSD17B3 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 HSD17B3-disrupted clones.
