Long-chain fatty acids are both important metabolites as well as signaling molecules. Fatty acid transport proteins are key mediators of cellular fatty acid uptake and recent transgenic and knockout animal models have provided new insights into their contribution to energy homeostasis and to pathological processes, including obesity and insulin desensitization.

Mitochondrial function is crucial for hepatic lipid metabolism. Current research identifies two types of mitochondria based on their contact with lipid droplets: peridroplet mitochondria (PDM) and cytoplasmic mitochondria (CM). This work aimed to investigate the alterations of CM and PDM in metabolic dysfunction-associated steatotic liver disease (MASLD) induced by spontaneous type-2 diabetes mellitus (T2DM) in db/db mice.

Background: The intestinal microbiota comprises all living microorganisms in the gastrointestinal tract and is crucial for its function. Clinical observations and laboratory findings confirm a central role of the microbiota in chronic inflammatory bowel diseases (IBD). However, many mechanistic details remain unclear.

Currently, the identification of valuable candidate genes affecting milk fat synthesis in dairy cows is still limited, and the specific regulatory mechanism is still unknown. In this study, we used primary bovine mammary epithelial cells(BMECs)as a model and utilized overexpression and knockdown techniques for the PI4K2A gene to investigate the specific mechanisms by which it regulates lipid metabolism in BMECs. We studied whether PI4K2A regulates the inhibition of trans-10, cis-12 conjugated linoleic acid (t10,c12-CLA) on lipid synthesis in BMECs.

Inflammation and oxidative stress play a pivotal role in COPD pathogenesis. Free fatty acids (FFA) as signaling molecules through a series of G-proteins coupled receptors, play an important role in regulation of the immune system and oxidative stress. For this reason, we decided to investigate the profile of FFA in the plasma in the COPD patients.

Cancer cachexia is a multifaceted metabolic syndrome characterized by muscle wasting, fat redistribution, and metabolic dysregulation, commonly associated with advanced cancer but sometimes also evident in early-stage disease. More subtle body composition changes have also been reported in association with cancer, including sarcopenia, myosteatosis, and increased fat radiodensity. Emerging evidence reveals that body composition changes including sarcopenia, myosteatosis, and increased fat radiodensity, arise from distinct biological mechanisms and significantly impact survival outcomes.
