Hindbrain catecholamine neurons control rapid switching of metabolic substrate use during glucoprivation in male rats.

Li AJ, Wang Q, Dinh TT, Wiater MF, Eskelsen AK, Ritter S (2013) Hindbrain catecholamine neurons control rapid switching of metabolic substrate use during glucoprivation in male rats. Endocrinology 154(12):4570-4579. doi: 10.1210/en.2013-1589

Summary: Previous work has shown that corticosterone secretion in response to glucoprivation is at least in part controlled by hindbrain catecholamine neurons in the paraventricular nucleus of the hypothalamus (PVH). In this work the authors investigate the metabolic consequences of lesioning these neurons. Rats received bilateral 82-ng infusions of Anti-DBH-SAP (Cat. #IT-03) into the PVH. Saporin (Cat. #PR-01) was used as a control. Although lesioned animals had the same energy expenditure and locomotor activity as controls, they also had a higher respiratory exchange ratio, indicating a reduced ability to switch from carbohydrate to fat metabolism in response to glucoprivation.
