GC11 Metabolism and Adipocyte Differentiation-Metabolic Syndrome

The research team on Adipobiology is a consolidated research group working on the identification and characterization of novel markers of adipose tissue dysfunction in obesity. Our research is aimed at elucidating the cellular and molecular mechanisms underlying the development of obesity-related comorbidities, including insulin resistance and type 2 diabetes. This research has a two-pronged approach: (a) targeted analyses of the regulation of insulin signaling and lipid storage and mobilization in adipocytes at the cellular and molecular levels, using a wide variety of cellular and molecular methodologies on adipocyte cell lines and primary human adipocytes, and (b) untargeted omics studies.

We employ in vitro models of insulin resistance to mimic different aspects of obesity and metabolic disease, as well as different approaches for the identification of protein networks relevant to adipose tissue function. Likewise, the relevance of impaired organelle function and inter-organelle contacts in obese adipocytes are also explored. Regarding the second approach, we employ several proteomic techniques to identify novel biomarkers and pathways activated and/or impaired in the two major fat depots, subcutaneous and visceral, and its separate components in lean and obese individuals with different degrees of insulin sensitivity. We have also established the protein fingerprint of the adipose tissue in lipodystrophy and after bariatric surgery-induced weight loss. Our omic studies also include the evaluation of the impact of obesity and insulin resistance on the activation and modification (phosphorylation, acetylation) of proteins of the adipose tissue. In collaboration with Dr. Feliciano Priego (GC-21 Metabolomics Identification/quantification of Bioactive Components) and Eduardo Chicano (The Proteomics Research Support Unit of IMIBIC), we have extended our omic studies to the lipidome, including MALDI Imaging, for comparative analyses of the adipose tissue from obese subjects with different degrees of insulin resistance or lipid droplets isolated from adipocytes.

Our current research projects are aimed at characterizing the impact of extracellular matrix composition and remodeling in obesity-associated adipocyte dysfunction and changes in macrophage phenotype in order to decipher novel molecular mechanisms that could pave the way to devise effective therapies in obesity and metabolic disease. Both 2D and 3D culture systems are employed as platforms for testing drugs, sera, or nanotechnology products with the aim of translating research findings to clinical applications.
