The present invention discloses a substance for inhibiting the KCNK3
gene and its application in regulating fat
metabolism or
ferroptosis. The present invention uses the
CRISPR / Cas9 technology to construct
gene knockout and overexpression
cell lines, and finds that the knockout of KCNK3 inhibits lipid synthesis and accumulation in porcine preadipocytes and promotes
lipolysis thermogenesis. Further, by using the technology of combined
transcriptome and
lipidome analysis, the KCNK3
gene knockout cells are analyzed, and it is found that KCNK3 regulates the biological processes of fat
metabolism and
ferroptosis. By detecting the
iron content, ROS level,
glutathione level, mitochondrial morphological characteristics, etc. in KCNK3 knockout PK15 cells, it is proved that the knockout of KCNK3 promotes
ferroptosis. The present invention discovers for the first time the role of the KCNK3 gene in promoting porcine fat formation and inhibiting ferroptosis, and this discovery has important significance for regulating porcine fat deposition by using the KCNK3 gene and for the treatment of human
obesity and ferroptosis-related diseases.
