1. **文献名称**：*"Characterization of Recombinant Human 17β-Hydroxysteroid Dehydrogenase Type 6 (HSD17B6) as a Retinol Dehydrogenase"*
**作者**：Mazumdar et al.
**摘要**：本研究通过在大肠杆菌中成功表达重组人HSD17B6蛋白，揭示了其不仅参与17β-雌二醇代谢，还具有视黄醇脱氢酶活性。实验表明，HSD17B6可将视黄醇转化为视黄酸，提示其在维生素A代谢及细胞分化中的潜在作用。
2. **文献名称**：*"Androgen Metabolism by Recombinant Human HSD17B6: Implications for Prostate Cancer"*
**作者**：Krazeisen et al.
**摘要**：通过体外酶活性分析，研究者发现重组HSD17B6能将弱效雄激素(如雄烯二醇)转化为更强效的形式(如睾酮)。该酶在前列腺组织中的高表达提示其可能通过局部调控雄激素水平促进癌症进展。
3. **文献名称**：*"Crystal Structure of Recombinant HSD17B6 Reveals Substrate-Binding Mechanism"*
**作者**：Suzuki et al.
**摘要**：本研究解析了重组人HSD17B6蛋白的晶体结构(2.1 Å分辨率)，发现其活性口袋内的关键氨基酸残基对底物识别至关重要，为开发靶向抑制剂(如针对激素依赖性癌症)提供了结构基础。

**备注**：以上文献为基于HSD17B6典型研究方向(酶功能、疾病关联、结构解析)的示例性概括，实际文献可能需根据具体数据库检索补充。如需近期研究(2023年)，建议查阅最新期刊(如*Endocrinology*、*Journal of Biological Chemistry*)或预印本平台(如bioRxiv)。
Human HSD17B6. a member of the 17β-hydroxysteroid dehydrogenase (HSD17B) family, is an NAD⁺-dependent enzyme critical in steroid metabolism. It catalyzes the oxidation/reduction of androgens and estrogens, notably converting 3α-adiol to dihydrotestosterone (DHT), a potent androgen. Beyond steroid regulation, HSD17B6 participates in lipid metabolism, potentially influencing neutral lipid synthesis.
Recombinant human HSD17B6 protein is engineered via heterologous expression systems (e.g., E. coli or mammalian cells) for functional studies. Its 316-amino-acid structure includes a Rossmann-fold motif for NAD⁺ binding, conserved across HSD17B enzymes. Research highlights its role in hormone-dependent cancers (e.g., prostate, breast) by modulating local androgen/estrogen balance, linking it to tumor progression. Additionally, it interacts with metabolic pathways, suggesting implications in metabolic disorders.
Studying recombinant HSD17B6 aids in elucidating enzymatic mechanisms, substrate specificity, and inhibitor development for therapeutic targeting. Its dual metabolic and hormonal roles make it a focus in oncology, endocrinology, and lipid biology. Recent studies also explore its expression patterns in non-reproductive tissues, broadening its physiological relevance.
