Article Abstract

Adipose tissue is a key regulator of systemic energy homeostasis and improving adipose tissue function provides a brand-new theoretical reference for the prevention and treatment of obesity. FLLL32, a curcumin analog, can hinder various carcinogenic processes, however, its role in adipose tissue has not been fully elucidated. In this study, we observed that FLLL32 treatment significantly improved cold intolerance and reduced white adipose tissue (WAT) adipocyte size in mice, but had no effect on body weight and adipose tissues weight. Furthermore, FLLL32 treatment upregulated the expression level of uncoupling protein 1 and downregulated the expression level of peroxisome proliferator-activated receptor gamma in adipose tissue. Additionally, FLLL32 promoted the mRNA level of transferrin receptor protein 1, a key iron transporter on the cell membrane, and the lipid peroxidation in inguinal WAT. Finally, FLLL32 significantly inhibited the differentiation and maturation of preadipocytes. In summary, our results demonstrated that FLLL32 plays a crucial role in regulating adipose tissue function.

Introduction: Pressure injuries (PIs) in patients with diabetes mellitus (DM) still impacts patients' health and places a heavy burden on healthcare systems. Stage I and stage II PIs are particularly prevalent among individuals with diabetes. Without timely and appropriate interventions, these injuries can progress to more severe stages, requiring prolonged recovery periods.

Objective: Vertical sleeve gastrectomy (VSG) promotes significant metabolic improvements, though the underlying molecular mechanisms are not fully understood. Emerging evidence suggests that small extracellular vesicles (sEVs) contribute to metabolic improvements post VSG, such as improved fatty liver disease or adipose tissue function; however, it is unclear how different organ-specific sEVs interact with various metabolic parameters. The objective of this study is to establish the role of organ-specific sEVs in the metabolic improvements post VSG.

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.
