Am J Physiol Cell Physiol 2021 09 8. Epub 2021 Sep 8.

Novo Nordisk Foundation Center for Basic Metabolic Research, Faculty of Health and Medical Sciences, University of Copenhagen, Denmark.

Skeletal muscle is an endocrine organ secreting exercise-induced factors (exerkines), which play a pivotal role in inter-organ crosstalk. Using mass spectrometry (MS)-based proteomics, we characterized the secretome and identified thymosin beta-4 (TMSB4X) as the most upregulated secreted protein in the media of contracting C2C12 myotubes. TMSB4X was also acutely increased in plasma of exercising humans irrespective of the insulin resistance condition or exercise mode. Read More

Biglycan: A regulator of hepatorenal inflammation and autophagy.

Matrix Biol 2021 06 10;100-101:150-161. Epub 2021 Jun 10.

Institute of Pharmacology and Toxicology, Goethe University, Frankfurt, Germany. Electronic address:

Soluble biglycan, a small leucine-rich proteoglycan, plays a significant role in several pathologies as it has emerged as an extracellular matrix-derived danger-associated molecular pattern. Biglycan is released from the extracellular matrix in response to tissue injury and, as a canonical danger signal, interacts with innate immune receptors, Toll-like receptors 2 and 4, thereby triggering a sustained inflammatory response. Recent evidence indicates that biglycan acts as a molecular switch between inflammation and autophagy by a specific interaction with the Toll-like co-receptor CD14 and CD44, respectively. Read More

Adipocyte PHLPP2 inhibition prevents obesity-induced fatty liver.

Nat Commun 2021 03 23;12(1):1822. Epub 2021 Mar 23.

Department of Medicine, Columbia University, New York, NY, USA.

Increased adiposity confers risk for systemic insulin resistance and type 2 diabetes (T2D), but mechanisms underlying this pathogenic inter-organ crosstalk are incompletely understood. We find PHLPP2 (PH domain and leucine rich repeat protein phosphatase 2), recently identified as the Akt Ser473 phosphatase, to be increased in adipocytes from obese mice. To identify the functional consequence of increased adipocyte PHLPP2 in obese mice, we generated adipocyte-specific PHLPP2 knockout (A-PHLPP2) mice. Read More

Zhe Huang Aimin Xu

Front Immunol 2021 25;12:608680. Epub 2021 Feb 25.

The State Key Laboratory of Pharmaceutical Biotechnology, The University of Hong Kong, Hong Kong, China.

Adipose tissue (AT) is a highly heterogeneous and dynamic organ that plays important roles in regulating energy metabolism and insulin sensitivity. In addition to its classical roles in nutrient sensing and energy storage/dissipation, AT secretes a large number of bioactive molecules (termed adipokines) participating in immune responses and metabolic regulation through their paracrine and/or endocrine actions. Adipose-derived extracellular vesicles (ADEVs), including exosomes, microvesicles (MVs), and apoptotic bodies, have recently emerged as a novel class of signal messengers, mediating intercellular communications and inter-organ crosstalk.

The Role of Exercise in the Interplay between Myokines, Hepatokines, Osteokines, Adipokines, and Modulation of Inflammation for Energy Substrate Redistribution and Fat Mass Loss: A Review.

Nutrients 2020 Jun 26;12(6). Epub 2020 Jun 26.

Tecnologico de Monterrey, Escuela de Medicina y Ciencias de la Salud, Ave. Morones Prieto 3000, Monterrey N.L. 64710, Mexico.

Exercise is an effective strategy for preventing and treating obesity and its related cardiometabolic disorders, resulting in significant loss of body fat mass, white adipose tissue browning, redistribution of energy substrates, optimization of global energy expenditure, enhancement of hypothalamic circuits that control appetite-satiety and energy expenditure, and decreased systemic inflammation and insulin resistance. Novel exercise-inducible soluble factors, including myokines, hepatokines, and osteokines, and immune cytokines and adipokines are hypothesized to play an important role in the body's response to exercise. To our knowledge, no review has provided a comprehensive integrative overview of these novel molecular players and the mechanisms involved in the redistribution of metabolic fuel during and after exercise, the loss of weight and fat mass, and reduced inflammation.
