  1. Nogueiras R, Williams L, Dieguez C. Ghrelin: new molecular pathways modulating appetite and adiposity. Obes Facts. 2010;3:285-92 pubmed publisher
    ..This review aims to summarize novel roles of ghrelin in energy balance, focusing particularly on both the newly identified neuronal pathways mediating the effects of ghrelin and on peripheral mechanisms leading to increased adiposity. ..
  2. Folgueira C, Beiroa D, González Rellán M, Porteiro B, Milbank E, Castelao C, et al. Uroguanylin Improves Leptin Responsiveness in Diet-Induced Obese Mice. Nutrients. 2019;11: pubmed publisher

  5. Quiñones M, Al Massadi O, Folgueira C, Bremser S, Gallego R, Torres Leal L, et al. p53 in AgRP neurons is required for protection against diet-induced obesity via JNK1. Nat Commun. 2018;9:3432 pubmed publisher
    ..Finally, p53 in AgRP neurons regulates the ghrelin-induced food intake and body weight. Overall, our findings provide evidence that p53 in AgRP neurons is required for normal adaptations against diet-induced obesity. ..
  6. Liñares Pose L, Rial Pensado E, Estévez Salguero Á, Milbank E, González García I, Rodriguez C, et al. Genetic Targeting of GRP78 in the VMH Improves Obesity Independently of Food Intake. Genes (Basel). 2018;9: pubmed publisher
    ..Overall, these results indicate that the modulation of GRP78 in the VMH may be a target against obesity. ..
  7. Quiñones M, Al Massadi O, Fernø J, Nogueiras R. Cross-talk between SIRT1 and endocrine factors: effects on energy homeostasis. Mol Cell Endocrinol. 2014;397:42-50 pubmed publisher
    ..In addition, we analyze the potential of targeting SIRT1 for the treatment of obesity and type 2 diabetes mellitus. ..
  8. Al Massadi O, López M, Fernø J, Diéguez C, Nogueiras R. What is the real relevance of endogenous ghrelin?. Peptides. 2015;70:1-6 pubmed publisher
    ..Despite the numerous reports using different genetically engineered mouse models targeting the ghrelin system, its endogenous relevance in metabolism seems to be less important than its pharmaceutical options. ..
  9. Al Massadi O, Müller T, Tschop M, Dieguez C, Nogueiras R. Ghrelin and LEAP-2: Rivals in Energy Metabolism. Trends Pharmacol Sci. 2018;39:685-694 pubmed publisher
    ..Here, we discuss not only the current understanding of LEAP-2 in metabolic regulation, but also the potential of this peptide in the treatment of obesity and other diseases that involve dysregulation of the ghrelin system. ..
