Analysis of programmed cell death during maturation of oocytes in miniature and normal

다국어 초록 (Multilingual Abstract)

In the present study of this experiment was to understand the expression of apoptotic gene expression in the ovary of miniature pigs and pigs on the 15th day of estrus. Also the compare and analyze of programmed cell death type(Apoptosis and autophagy) expression pattern during mature oocyte on the miniature and normal pig cells. Analysis of mRNA gene expression of ovary in miniature and normal pigs on the 15th day of estrus showed that the expression of genes related to Autophagy (ATG13, MAP1LC3, Beclin1) was high in normal pigs but the expression of ATG1 and ATG5 genes was low. In addition, the expression of genes related to apoptosis (Casp-3, BAX) was high in the mini pigs, and the gene related to the LH hormone was high in the miniature pigs, whereas the expression of the gene related to the FSH hormone was high in the normal pigs. On the other hand, the result of muture oocyte on the miniature and normal pig cells is the expression of Casp-3 protein was moust high from treatment of FL+rapa (FSH+LH and Rapamycin) of the oocyte on the miniature pig cell. However, MAP1LC3 expression was higher in the oocytes of treatment of rapanycine treatment on the nomal pig cells. There was no gene expression in cumulus cells of matured oocytes in mini pig cells, whereas MAP1LC3 expression was higher in oocyte cumulus cells matured in normal pig cells. It was confirmed that the miniature and normal pigs showed different programmed cell death patterns, In the case of oocytes matured in miniature pig cells, MAP1LC3 gene expression was found to be low in spite of treatment with Autophagy regulator.
