Exploring the Role of Oleic Acid in Muscle Cell Differentiation: Mechanisms and Implications for Myogenesis and Metabolic Regulation in C2C12 Myoblasts.

: Myogenesis, the process by which myoblasts differentiate into multinucleated muscle fibers, is tightly regulated by transcription factors, signaling pathways, and metabolic cues. Among these, fatty acids have emerged as key regulators beyond their traditional role as energy substrates. Oleic acid, a monounsaturated fatty acid, has been shown to modulate muscle differentiation, potentially influencing myogenic pathways.

Pharmacological potential of endocannabinoid and endocannabinoid-like compounds in protecting intestinal structure and metabolism under high-fat conditions.

The intestine plays a crucial role in nutrient absorption, digestion, and regulation of metabolic processes. Intestinal structure and functions are influenced by several factors, with dietary composition being one of the most significant. Diets rich in various types of fats, including saturated, monounsaturated, and polyunsaturated fats, have distinct effects on intestinal cell metabolism and overall intestinal health.

Insight into the Regulation of NDRG1 Expression.

The N-Myc Downstream Regulated Gene 1 (NDRG1) protein, a member of a family of four, has emerged as a key regulator of various physiological and pathological processes. Extensive knowledge has been gained on the modulation of NDRG1 expression during endoplasmic reticulum stress, autophagy, and hypoxia. Moreover, new functions have emerged in recent years.

M1-derived extracellular vesicles polarize recipient macrophages into M2-like macrophages and alter skeletal muscle homeostasis in a hyper-glucose environment.

Background: Macrophages release not only cytokines but also extracellular vesicles (EVs). which are small membrane-derived nanovesicles with virus-like properties transferring cellular material between cells. Until now, the consequences of macrophage plasticity on the release and the composition of EVs have been poorly explored.
