Brain-derived neurotrophic factor (BDNF) plays a key role in neuronal development, synaptic plasticity, and the central control of energy homeostasis. Peripheral metabolic signals such as leptin and glucose regulate hypothalamic BDNF gene expression. However, the effects of long-term hyperglycemia and/or hyperinsulinemia on BDNF mRNA levels in the(More)
Galanin-like peptide (GALP) neurones participate in the metabolic control of reproduction and are targets of insulin and leptin regulation. Phosphoinositide 3-kinase (PI3K) is common to the signalling pathways utilised by both insulin and leptin. Therefore, we investigated whether PI3K signalling in neurones expressing GALP plays a role in the(More)
Hypothalamic kisspeptin neurons integrate and translate cues from the internal and external environments that regulate gonadotropin-releasing hormone (GnRH) secretion and maintain fertility in mammals. However, the intracellular signaling pathways utilized to translate such information into changes in kisspeptin expression, release, and ultimately(More)
