Kinases represent one of the largest druggable families of proteins. Importantly, many kinases are aberrantly activated/de-activated in multiple organs during obesity, which contributes to the development of diabetes and associated diseases. Previous results indicate that the complex between Extracellular-regulated kinase 3 (ERK3) and Mitogen-Activated Protein Kinase (MAPK)-activated protein kinase 5 (MK5) suppresses energy dissipation and promotes fatty acids (FAs) output in adipose tissue and, therefore promotes obesity and diabetes. However, the therapeutic potential of targeting this complex at the systemic level has not been fully explored.

MK5 mRNA levels in subcutaneous adipose tissue in healthy lean subjects obese subjects.

Here we applied a translational approach to target the ERK3/MK5 complex in mice. Importantly, deletion of ERK3 in the whole body or administration of MK5-specific inhibitor protects against obesity and promotes insulin sensitivity. Finally, we show that the expression of ERK3 and MK5 correlates with the degree of obesity and that ERK3/MK5 complex regulates energy dissipation in human adipocytes.

Altogether, we demonstrate that ERK3/MK5 complex can be targeted in vivo to preserve metabolic health and combat obesity and diabetes.

Predoctoral contract in metabolism and cardiac disease

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

  • 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.
Predoctoral contract in metabolism and cardiac disease

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 ).
