Slc35d3對脂肪、肝臟、腎臟組織中脂代謝的影響
[Abstract]:Background and objective Obesity is a complex chronic disease and one of the most important manifestations of metabolic syndrome in the 21st century. Obesity is closely associated with risk factors for cardiovascular disease, such as insulin resistance, diabetes, hypertension, and dyslipidemia. The liver is the largest fatty acid synthesis and metabolic organ in the body. The synthesized fatty acids are released into the blood with the help of apolipoprotein and stored in the lipid bank or provide energy for other tissues and organs. Adipose tissue is the largest energy storage organ in the body. The excess energy is stored in the form of fat. When the energy is insufficient, fat mobilization occurs to meet the needs of the body. Fatty degeneration is easy to occur in parenchymal organs such as liver, heart and kidney, in which lipid metabolism is crucial. SLC35D3 gene encodes a nucleotide transporter. It has been reported that Slc35d3 is a candidate gene for obesity or metabolic syndrome, whose protein is located in the endoplasmic reticulum and interacts with D1R. Mice with Slc35d3 gene mutation can attenuate dopamine signal in striatal neurons. This led to metabolic syndrome, and mutations in the SLC35D3 gene were found in two patients with metabolic syndrome. The purpose of this study was to investigate the effect of SLC35D3 gene on lipid metabolism in fat, liver and kidney tissues. Methods the changes of Slc35d3 mRNA transcription in fat, liver and kidney of DIOB6J (diet-induced obesity) mice, ob/ob (leptin deficient) mice and normal control C57BL/6J mice were detected by fluorescence quantitative PCR. Human SLC35D3 gene was electrotransfected into human adipocytes 6 days after differentiation of 3T3-L1. The effects of SLC35D3 gene on differentiation index and mRNA level of lipid metabolism related gene were observed. At the same time, glucose consumption was also detected. At the same time, the SLC35D3 gene was overexpressed in HepG2 cells by liposome transfection. After two days of transfection, the effect of liposome transfection on the mRNA level of lipid metabolism-related genes was detected. On the third day, 1000uM oleic acid and palmitic acid were used to detect the expression of lipid metabolism-related gene mRNA for 24 h, and the normal medium was restored to culture for 24 h after stimulation, and the effect on the mRNA level of lipid metabolism-related gene was detected. Human SLC35D3 gene was transfected into 293T cells by liposome. The changes of lipid metabolism-related gene transcription level were detected after transfection for 2 days. Results in DIO B6J mice and ob/ob obese mice, the transcription level of Slc35d3 in fat and kidney tissues was significantly lower than that in C57BL/6J control group (P0.01). In the liver tissue of obese mice, the transcription level of Slc35d3 was significantly higher than that of control group (P0.01). After 6 days of differentiation of 3T3-L1 preadipocytes, human SLC35D3 gene was overexpressed. The expression of adipocyte differentiation index gene and lipid metabolism-related gene mRNA was significantly decreased, but glucose consumption was not significantly different. HepG2 cells overexpressed human SLC35D3 gene. The mRNA expression of lipid metabolism-related genes was also significantly decreased, and the mRNA expression of lipid metabolism-related genes was also significantly decreased after 293T cells over-expressed the human SLC35D3 gene. Conclusion SLC35D3 can be used as a candidate gene for the study of obesity or metabolic syndrome because of its down-regulation of adipocyte differentiation related genes and lipid metabolism-related genes in adipose, liver and kidney tissues.
