Fig. 5From: Effect of starvation on brain glucose metabolism and 18F-2-fluoro-2-deoxyglucose uptake: an experimental in-vivo and ex-vivo studyMetabolic machinery of starved brain. In each panel, green bars represent the brain homogenate of control (CTR) mice and the blue bars represent the brain homogenate of starved (STS) mice. a The PFK activity expressed in mU × mg of proteins−1 ± SD of at least three experiments. The catalytic activity was reduced in STS brain homogenate with respect to CTRBack to article page
