Nuestra compañera Beatriz Cicuéndez reconoce que necesita «tener aficiones que la saquen del laboratorio porque investigar engancha».

at the CNIC
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).
ELEGIBILITY CRITERIA
If you are interested, please send your CV, academic record, a letter of interest and contact details of previous references to Laura Grau (lgrau@cnic.es) 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 ).

During the first weeks of postnatal heart development, cardiomyocytes undergo a major adaptive metabolic shift from glycolytic energy production to fatty acid oxidation. This metabolic change is contemporaneous to the up-regulation and activation of the p38γ and p38δ stress-activated protein kinases in the heart.
We demonstrate that p38γ/δ contribute to the early postnatal cardiac metabolic switch through inhibitory phosphorylation of glycogen synthase 1 (GYS1) and glycogen metabolism inactivation. Premature induction of p38γ/δ activation in cardiomyocytes of newborn mice results in an early GYS1 phosphorylation and inhibition of cardiac glycogen production, triggering an early metabolic shift that induces a deficit in cardiomyocyte fuel supply, leading to whole-body metabolic deregulation and maladaptive cardiac pathogenesis. Notably, the adverse effects of forced premature cardiac p38γ/δ activation in neonate mice are prevented by maternal diet supplementation of fatty acids during pregnancy and lactation.
These results suggest that diet interventions have a potential for treating human cardiac genetic diseases that affect heart metabolism.
