Abstract:

In order to explore the expression of uncoupling protein 3(UCP3)in different tissues of Min pig and its effect on the expression of mitochondrial-related genes and ATP synthase-related genes in Min pig preadipocytes,the back adipose tissue of 1-month-old Min pig was collected as the research material.The preadipocytes were isolated by enzymatic digestion and cultured in vitro.At the same time,axillary fat,chest fat,back fat,inguinal fat,perirenal fat and intramuscular fat were collected to construct tissue expression profiles.Real-time Quantitative PCR was used to detect the expression of MCU family genes(MCU,MICU1,MICU2),ATP synthase(ATP5B,ATP5E)and 1,4,5-trisphosphate inositol receptor type 1(ITPR1)genes and the expression of UCP3 gene in different adipose tissues by in vitro transfection of UCP3 gene overexpression vector or interference fragment.The results showed that the enzymatic digestion method could quickly obtain sufficient preadipocytes in the back adipose tissue.The cell edge had good refractive index,clear boundary,and similar morphology to fibroblasts.UCP3 gene was expressed in different adipose tissues,with the highest expression in dorsal adipose tissue and the lowest expression in abdominal fat.After overexpression of UCP3 gene,the expression levels of MCU family genes and ITPR1 genes were significantly increased,and the expression level of ATP5B gene was significantly decreased.After UCP3 gene interference,the expression levels of MCU family genes and ITPR1 genes were significantly decreased,and the expression levels of ATP synthase genes were significantly increased.The results showed that UCP3 gene was differentially expressed in different adipose tissues,which could promote the expression of MCU family genes and ITPR1 genes and inhibit the expression of ATP5B gene.

Key words: Min pig, Uncoupling protein 3, Real-time PCR, Preadipocytes, Heat-related genes
