Metabolism of bioactive lipids
The Laboratory focuses on the analysis of lipid mediators (eicosanoids, docosanoids, endocannabinoids) using the UPLC-MS/MS method, in particular to identify the source of production of various mediators and their effect on metabolism and immune cells (i.e. adipocytes vs. macrophages). Currently, the lab is exploring new anti-diabetic lipids, fatty acid esters of hydroxy fatty acids and lipid-related metabolic pathways using stable isotopes and LIMeX platform.

White adipose tissue (WAT) is a complex endocrine organ and its low-grade inflammation in obesity contributes to the development of metabolic disorders. In 2014, a class of WAT-born lipid mediators - fatty acid esters of hydroxy fatty acids (FAHFA) was discovered. FAHFAs are endogenous lipids with anti-inflammatory and anti-diabetic properties, including the enhancement of glucose tolerance, and insulin and glucagon-like peptide 1 (GLP-1) secretion while reducing inflammatory responses [1-5].

Naturally occurring long-chain omega-3 PUFA, namely eicosapentaenoic acid (EPA; 20:5 ω-3), docosapentaenoic acid (DPA; 22:5 ω-3), and docosahexaenoic acid (DHA; 22:6 ω-3) exert multiple biological effects...

MetaboAnalyst is a great tool for analysis of metabolomics data. Here are some tips how to install MetaboAnalyst locally on a linux workstation. Such installation could be tailored to meet individual requirements (default setting, fonts, etc.).
Starting point is a runnig installation of Ubuntu 18.04.3 LTS.

CRediT (Contributor Roles Taxonomy) is high-level taxonomy, including 14 roles, that can be used to represent the roles typically played by contributors to scientific scholarly output. The roles describe each contributor’s specific contribution to the scholarly output. This web tool helps to summarize contributions of individual authors and prepare the Author contributions paragraph for a scientific journal.

The main objective of this project is to explore structure, mechanisms of action, anti-inflammatory and anti-diabetic effects of novel lipokines – branched fatty acid esters of hydroxy fatty acids derived from polyunsaturated fatty acids of n-3 series (Omega-3) using obesity and inflammation models.

Obesity is associated with an increased risk of developing metabolic syndrome, type 2 diabetes and cardiovascular disease. The adipose tissue significantly affects the whole-body metabolism of carbohydrates and lipids, which also involves fatty acid esters of hydroxy fatty acids (FAHFA), lipid mediators that affect glucose uptake and insulin sensitivity in target tissues. Our goal is to identify the metabolic pathways between lipid synthesis and antioxidant defense involved in FAHFA biosynthesis, to examine the substrate specifity of the candidate enzyme, and to introduce a methodology for the quantification of metabolic fluxes through redox reactions linking central carbon metabolism and nicotinamidadene cofactor-driven reductive biosynthesis.
