*Glycolysis↑, BA elevates the rates of cellular glucose uptake and aerobic glycolysis in mouse embryonic fibroblasts with concomitant reduction of glucose oxidation.
*GlucoseCon↑, BA increases cellular glucose uptake
*Apoptosis↓, Without eliciting signs of obvious cell death BA leads to compromised mitochondrial function, increased expression of mitochondrial uncoupling proteins (UCP) 1 and 2, and liver kinase B1 (LKB1)-dependent activation AMP-activated protein kinase.
*UCP1↓,
*AMPK↑, AMPK activation accounts for the increased glucose uptake and glycolysis which in turn are indispensable for cell viability upon BA treatment.
GLUT1↑, The expression of glucose transporter GLUT1 was elevated upon BA treatment for 16 h
mt-ROS↑, We observed increased production of mitochondrial ROS (Fig. 4A) and elevated expression of uncoupling proteins UCP1 and UCP2 in BA-treated MEF
