Sea buckthorn oil enhances proliferation, adipocytes differentiation and insulin sensitivity in 3T3-L1 cells. - GreenMedInfo Summary

The objective of this study is to investigate the effects of sea buckthorn oil (SBO) on proliferation, adipogenic differentiation and insulin sensitivity of 3T3-L1 cells. Results showed that SBO increased cell proliferation ability, accompanied by up-regulated proliferating cell nuclear antigen content ( < 0.05) and p38 activity ( < 0.05). SBO also promoted adipogenesis and enhanced adipogenic transcriptional factors expression. Mitochondrial biogenesis related gene expressions were elevated in SBO treated cells ( < 0.05). Of note, SBO also increased glucose uptake and glucose transporter 4 abundance ( < 0.05). Cells treated with SBO exhibited greater phosphorylated insulin receptor substrate 1 ( < 0.05), phosphorylated-Akt ( < 0.05) and phosphorylated AMP-activated protein kinase ( < 0.01) contents. When taken together, these results suggest that SBO promotes 3T3-L1 cells proliferation, adipogenesis and insulin sensitivity.
