Los dos proyectos científicos que ofrecemos este año son:
Stress in the brain, metabolic effects: Obesity has become a new pandemic. It is known that obesity induces molecular changes in the brain that are fundamental for the development of diseases and for maintaining excess energy intake. However, little is known about how these changes appear and the molecular mechanisms that mediate them. We will study how modulating stress in the central nervous system induced by high fat diet affects the development of cardiometabolic diseases. For this purpose, genetically modified animals will be used and whole organism metabolism will be evaluated, and how the signalling of this stress in the brain affects the response of distant organs through inter-tissue communication.
Role of adipose tissue controling whole body homeostasis: Cardiometabolic diseases (CMDs)—e.g., diabetes, steatohepatitis, and cardiomyopathy— are the leading cause of death worldwide. Adipose tissue (AT) heterogeneity and dysfunction might be involved in the CMD pathogenesis. We have recently demonstrated that i) AT regulates whole-body metabolism independently of obesity and predisposes to hepatic cancer in mice and humans; and ii) molecules secreted by AT trigger liver steatosis and insulin resistance. Our studies suggest that dysfunctional AT communicates with other organs and induces pathogenic adaptive responses through evolutionarily conserved mechanisms (rodent to humans). Our preliminary results show that AT dysfunction caused by mitochondrial alteration induces cardiomyopathy in lean mice, reinforcing that AT has a central role in controlling heart functionality.
We are seeking a highly motivated candidate, who would like to start a scientific career doing their doctoral thesis working in understanding the molecular mechanisms involved in how metabolic alterations can affect the cardiac disease, focusing on cardiac metabolism and how the rest of the organs affect it. This work will be supervised by Dr. Guadalupe Sabio.
We offer incorporation to CNIC via an FPU predoctoral contract (FPU 2021 call).
This call is open to applicants from all nationalities holding a Master’s degree in Biomedical Sciences and an academic record with average grade over 8,7 (out of 10).
An excellent academic record and previous research experience during their undergraduate period will be valued very positively.
Authorship of publicacions in indexed journal will be valued very positively.
Candidates must have a solid working knowledge of English.
If you are interested, please send your CV, academic record, a letter of interest and contact details of previous references to Laura Grau (firstname.lastname@example.org) indicating in the subject: “FPU2021 Guadalupe Sabio’s lab” no later than December 7th 2021.
Interested candidates will also need to apply officially throught the official governmental application for this predoctoral program (additional information: FPU 2021 call ).
As in previous years, our group is open to master and advanced undergraduate students for extending their scientific training through hands-on experience in our laboratory during the summer recess (1 July – 30 September). In addition to carrying out a supervised research project, the students will also attend CNIC seminars.
The aim of the CICERONE program is to give university students first-hand knowledge of biomedical research so that they can make more informed choices about the possibility of pursuing a scientific career.
For the 2019 call, we are offering the following research projects:
Role of p38MAPK in metabolic diseases: Metabolic syndrome is a medical disorder defined by the co‐occurrence of obesity, impaired glucose tolerance, dyslipidemia and hypertension. Stress activated protein kinases have been shown to control both obesity by itself and diabetes associated to obesity. These stress kinases are activated by several MAPK activated kinases (MKK). We want to investigate the role of MKK3 in this process and the molecular mechanism by which this kinase could affect diabetes.
p38MAPK in heart physiology: The p38MAPK pathway transduces a variety of extracellular signals regulating cellular responses to stress, being implicated in cell proliferation, differentiation and apoptosis. Its implication in the development of human diseases it is being deeply studied. Four p38MAPK family members have been identified: p38α, β, γ and δ. Preliminary data from our laboratory show that these kinases may control cytokine production during acute and chronic inflammatory processes. Moreover, studies with genetically modified mice made in our laboratory confirm that p38MAPKs have a role in the development of the heart. Our main objective is to determine if the regulation of the p38MAPK signalling pathway could have beneficial effects in the cardiac response to exercise.
