Abstract: Intrauterine growth restriction (IUGR) is a disease that affects many pregnant women and their growing fetuses. Hypoxia and shallow invasion are key characteristics of IUGR. A lack of oxygen has been shown to affect the mitochondria, which produces the energy in the cell. Pyruvate Kinase M2 (PKM2) is a metabolic enzyme known to be involved during hypoxia. Our objective was to determine the role of hypoxia in mitochondrial function, trophoblast cell invasion, and PKM2.

Human placenta tissues were collected at term to characterize the mitochondria in the cells. Human trophoblast cells were used to determine PKM2 expression. Treatment was with hypoxia, Shikonin, or Rapamycin to observe mitochondrial function and invasion characteristics of the trophoblast cells. The cells were lysed after treatment and western blots were performed to view PKM2 expression.

Hypoxic treated cells showed a decrease in mitochondrial function, invasion, and nuclear and cytostolic PKM2. Shikonin treated cells showed a decrease in invasion and nuclear PKM2, and an increase in mitochondrial function. โ€ข Keywords: Human cytotrophoblast Sw71 cells
