Abstract:SCD1 (stearoyl-coenzyme A desaturase 1) gene is the key regulatory gene for the synthesis of monounsaturated fatty acids, and plays an important role in lipid metabolism of tumor. Studies have shown that SCD1 is overexpressed in many malignant tumors and involved in many aspects of tumor development, including cell proliferation, cell cycle, apoptosis and metastasis. SCD1 has become a new target for tumor therapy and its inhibitors have shown significant antitumor activity in in vivo and in vitro experiments. The function of SCD1 in tumor and the development of SCD-1 inhibitors as anti-cancer agents in recent years are reviewed in this article.
