Metformin, a first-line treatment for type 2 diabetes mellitus (T2DM), has garnered attention due to its pleiotropic effects beyond glycemic control. In addition to improving insulin sensitivity and inhibiting hepatic gluconeogenesis, metformin modulates inflammation, oxidative stress, and cellular metabolism, particularly within adipose tissue. Adipose tissue is a crucial endocrine organ that plays a central role in metabolic homeostasis and is integral to obesity and T2DM pathogenesis. This review discusses the actions of metformin on white and brown adipose tissues, extracellular matrix remodeling, mature adipocytes, and adipose-derived stem cells. Through both AMP-activated protein kinase-dependent and independent pathways, metformin influences adipogenesis, lipolysis, adipokine secretion, fibrosis, and cellular senescence. We also focus on how the drug concentration influences its biological effects, emphasizing the necessity of physiologically relevant experimental models. These insights deepen our understanding of metformin's therapeutic potential in metabolic and age-related disorders.

Adipose tissue is rapidly expanding early in life. Elucidating the queues facilitating this process will advance our understanding of metabolically healthy obesity. Using single-cell RNA sequencing, we identified compositional differences of prewean and adult murine subcutaneous adipose tissue.

Human Dental Pulp Stem Cells (hDPSCs) represent a remarkable cell source for tissue engineering and regenerative medicine, offering significant potential for use in personalized medicine and autologous therapies. Decellularized extracellular matrix (ECM)-derived biological scaffolds show excellent properties for supporting cell delivery and growth in both in vitro and in vivo applications. These scaffolds provide essential biochemical cues that regulate cellular functions and offer a more accurate representation of the in vivo environment.

Obesity is a multifactorial disease characterized by excessive accumulation of adipose tissue, resulting from an imbalance between energy intake and expenditure. Mouse models have emerged as invaluable tools for elucidating the complex genetic, environmental, and physiological mechanisms driving to obesity. This chapter provides an overview of the methodologies employed to establish and study obesity in mice, highlighting their relevance to human disease.

Young females have higher circulating docosahexaenoic acid (DHA) levels than males, though the metabolic basis remains incompletely understood. Building on previous findings demonstrating higher hepatic synthesis of the DHA precursor, docosapentaenoic acid (DPAn-3) in males, this study extends the investigation to n-3 PUFA turnover in extrahepatic tissues of male and female C57BL/6N mice using compound-specific isotope analysis (CSIA). Animals were fed a 12-week diet enriched in either α-linolenic acid (ALA), eicosapentaenoic acid (EPA), or DHA, starting with a 4-week phase containing low carbon-13 (δC)-n-3 PUFA, followed by an 8-week phase with high δC-n-3 PUFA (n = 4 per diet, time point, sex).

Objective: This study aimed to enhance major adverse cardiovascular events (MACEs) prediction by pericoronary adipose tissue attenuation (PCATa) in non-obstructive coronary artery disease (CAD) patients when combined with lipoprotein (a) (Lp(a)).
Methods: A total of 1052 patients with non-obstructive CAD were included. Detailed clinical data and CCTA features were analyzed.
