Salidroside improves porcine oocyte maturation and subsequent embryonic development by promoting lipid metabolism
THERIOGENOLOGY(2022)
摘要
An optimal lipid droplet (LD) content is essential for successful mammalian embryonic development. Salidroside (SAL) is a traditional Chinese medicine and one of the important active components of the Rhodiola plant. SAL possesses antioxidative, anti-aging, and cardiovascular properties. Here, we studied the effects of SAL on in vitro maturation (IVM) of porcine oocytes and the subsequent embryonic development after parthenogenetic activation (PA). We found that 100 mu M of SAL had no effect on the extrusion rate of the first polar body of porcine oocytes but significantly improved the subsequent blastocyst formation rate and embryo quality. Our study further revealed that SAL treatment altered the morphology, increased the lipid content in oocytes, increased mitochondrial number. Further analysis revealed that SAL upregulated the expression of genes related to lipid metabolism (FASN, FADS1, HSL, and CPT1a) and the mitochondria function-related genes (PGC-1 alpha). These results suggest that SAL supplementation enhances oocyte maturation and subsequent embryonic development by promoting lipid metabolism, providing the necessary energy for the aforementioned processes.
