MOLECULAR METABOLISM AND DISEASE

Department of Biochemistry and Molecular Biomedicine Faculty of Biology. University of Barcelona

Our research group is focused on the study of the molecular and physiological basis of control of energy metabolism, and how it relates to human pathologies. We study the molecular mechanisms of brown, beige and white adipocyte plasticity, as well as muscle and hepatic metabolism. Molecular actors conveying new metabolic and endocrine functions of cells, tissues and organs are identified and characterized. Identification of the signaling molecules determining cellular and organ cross-talk is a main research subject.

Since the affiliation of our research team at Institut de Recerca Sant Joan de Deu, a fruitful program of collaborative research in pediatric endocrinology has developed with the team leaded by Dr. Lourdes Ibàñez. Recent results on the importance of sex differences in brown fat activity in the first year of life and the role of the batokine CXCL14 have been presented at the III IRSJD Scientific Meeting  held at Facultat de Biologia, University of Barcelona, the last  October, 28 These results have been recently published at J Clin Endocr Metab.



 




Obesity is expanding in dogs leading to disease conditions in these domestic pets and affecting their quality of life and that from their owners. Moreover, management of obesity in pets has relevant economic implications. F.Villarroya participated as invited speaker in the on-line symposium with a presentation on the mechanisms involved in the pathogenic consequences of hypertrophied fat, plasticity of adipose tissue and evidence of these phenomena in dogs.

 




The event of presentation of Sanna Laurila thesis, from the PET laboratory at the University of Turku, took place last 13 August, with Francesc Villarroya acting as opponent, a honorary role for doctorate qualification in the Finish University. The work by S.Laurila was related to the role of secretin in the control of human brown adipose tissue activity and was developed in the laboratory of K.Virtanen and P.Nuutila, international leader in research on human brown fat.





In line with our affiliation to Institut de Recerca Sant Joan de Déu (IRSJD), we participated in a study published recently in Science Translational Medicine (DOI: 10.1126/scitranslmed.abb0322), the prestigious journal from the Science group. This research, led by Dr. Carles Lerin at IRSJD, identified an inverse relationship between maternal breast milk betaine content and infant growth, and it was demonstrated that  maternal betaine supplementation during lactation induced a transient increase in offspring intestinal Akkermansia abundance, and reduced early weight gain. Furthermore, it was shown that maternal betaine supplementation decreased adiposity and improved glucose metabolism throughout adulthood, demonstrating a link between breast milk betaine content and long-term metabolic health. Our participation in this study is a follow up of  our long standing research on the molecular basis of the healthy properties of breastfeeding.

The  Integrase Strand Transfer Inhibitor (INSTI) antiretrovirals are  among the last generation drugs to treat HIV-infected patients. Recent data indicate that these patients show abnormally increased adiposity after treatment. Thus, the HIV infection and global obesity epidemics meet to confer to HIV patients increased metabolic and cardiovascular comorbidities.The coordinated research projects  will assess the molecular and cellular basis of such phenomenon and will identify potential targets of preventive intervention.



That system, in which bradykinin is a main actor, has been traditionally associated with the physiology of the renal and cardiovascular systems and processes of inflammation and pain. Our study, led by Dr.M.Peyrou, Juan de la Cierva researcher at our lab, reports that the kallikrein-kinin system acts as mechanism of molecular self-control of brown and beige adipose tissue thermogenic activation, and could help prevent the harmful effects of excessive activation of brown adipose tissue occurring in some pathological conditions such as cachexia or recovery from severe burns.The full article is accessible at:   https://rdcu.be/b3Ud4



A project on hepatocarcinogenesis and metabolic lipotoxity, led by Francesc
Villarroya, has been one of the initiatives selected by the AECC, in the category of Ideas Semilla 2019. F. Villarroya was in charge of representing the project in the commemorative act that the AECC held on September 24, in the Reina Sofía Museum in Madrid, on the occasion of World Research Day in Cancer (World Cancer Research Day).
In this edition, the AECC Scientific Foundation Research programs awarded 171 projects worth about 21 million euros, which integrate from great innovative and disruptive ideas to projects financed in a coordinated manner with large European foundations. Our focus is to investigate whether brown fat activation could be protective against liver cancer, as preliminary studies in our laboratory suggest.

Ruben Cereijo is a post-doctoral researcher, assistant professor at UB, member of our research team. The “Societat Catalana de Biologia” Young Researcher Award is for his doctoral thesis “Nous actors moleculars en la fisiologia del teixit adipós i pathologies associades”, read in the University of Barcelona in 2015, and the award to the best article is for the paper “CXCL14, a brown adipokine that mediates brown-fat-to-macrophage communication in thermogenic adaptation”, published in the prestigious scientific journal Cell Metabolism in 2018  (https://www.ncbi.nlm.nih.gov/pubmed/30122557). According to this study, the CXCL14 protein –formerly related to tumor progression and organogenesis- is synthetized by the brown adipose tissue and can activate cells with anti-inflammatory activity –M2 macrophages-, which have beneficial effects on metabolism and protect against type II diabetes and obesity. The prizes were given to the winners in the ceremony of the 4th Night of Biology, held in the Ramon Margalef Auditorium of CosmoCaixa Barcelona on July 10.

Meteorin-like/Meteorin-β protects heart against cardiac dysfunction

Meteorin-like/Meteorin-β (Metrnl/Metrnβ) is a secreted protein produced by skeletal muscle and adipose tissue that exerts metabolic actions that improve glucose metabolism. The role of Metrnβ in cardiac disease is completely unknown. Here, we show that Metrnβ-null mice exhibit asymmetrical cardiac hypertrophy, fibrosis, and enhanced signs of cardiac dysfunction in response to isoproterenol-induced cardiac hypertrophy and aging. Conversely, adeno-associated virus-mediated specific overexpression of Metrnβ in the heart prevents the development of cardiac remodeling. Furthermore, Metrnβ inhibits cardiac hypertrophy development in cardiomyocytes in vitro, indicating a direct effect on cardiac cells. Antibody-mediated blockage of Metrnβ in cardiomyocyte cell cultures indicated an autocrine action of Metrnβ on the heart, in addition to an endocrine action. Moreover, Metrnβ is highly produced in the heart, and analysis of circulating Metrnβ concentrations in a large cohort of patients reveals that it is a new biomarker of heart failure with an independent prognostic value.
