Stearoyl-CoAdesaturase-1 (SCD-1) is a key regulator of monounsaturated fatty acid synthesis. It plays a vital role in lipid synthesis and metabolism. Ca²⁺ is an important cation in the body and plays an important role in the organism. The aims of this study were to investigate the correlation of SCD-1 gene overexpression with lipid indexes and calcium ion level. The pcDNA3.1 (+) + SCD-1 +Flag eukaryotic expression vector and cultured duck uterine epithelial cells were co-transfected. The overexpression of SCD-1 gene was measured using the Flag Label Detection Kit. Ca ions and lipid contents were detected through Fluo-3/AM Calcium Ion Fluorescence Labeling method and Lipid Measuring Kit, respectively. SCD-1 gene overexpression was negatively correlated with triglyceride (TG) and high-density lipoprotein cholesterol (HDL-C), and positively correlated with Ca ion, total cholesterol (TC), very low-density lipoprotein cholesterol (VLDL-C) and low density lipoprotein cholesterol (LDL-C) levels. Meanwhile, Ca ion was positively correlated with TG, LDL-C and HDL-C contents, and negatively correlated with TC and VLDL-C levels. Overexpression of SCD-1 gene could regulate Ca ion secretion, as well as lipid synthesis and transport in duck uterine epithelial cells.
