Molecular Regulation of Adipogenesis and Anti-Obesity Mechanisms

The formation of adipose tissue is governed by a tightly orchestrated network of transcription factors, signalling pathways and epigenetic modifiers that guide multipotent precursor cells into lipid-storing adipocytes. Central to this process are peroxisome proliferator-activated receptor γ (PPARγ) and CCAAT/enhancer-binding proteins (C/EBPs), which activate gene programmes for lipid uptake, storage and endocrine function. Upstream signals—including insulin-mediated PI3K/Akt, MAPK cascades and Wnt/β-catenin—coordinate mitotic clonal expansion and lineage commitment, while energy sensors such as AMP-activated protein kinase (AMPK) shift cellular metabolism towards catabolism and thermogenesis. Post-translational mechanisms, notably ubiquitination and deubiquitination, fine-tune the stability of key regulators. In parallel, dietary bioactives and small-molecule inhibitors have emerged as modulators of adipogenic differentiation, either by antagonising master transcription factors or by activating browning programmes in white adipose depots. Together, these insights illuminate molecular entry points for interventions aimed at curbing adipose expansion, improving insulin sensitivity and addressing the global burden of obesity.

Molecular Regulation of Adipogenesis and Anti-Obesity Mechanisms publication trend

The graph below shows the total number of articles in molecular regulation of adipogenesis and anti-obesity mechanisms across all publications each year (not limited to Nature Index journals).

Technical terms

Adipogenesis: Differentiation process by which precursor cells become mature adipocytes capable of lipid storage and endocrine function.

Peroxisome proliferator-activated receptor γ (PPARγ): Nuclear receptor that drives expression of genes essential for adipocyte maturation and lipid metabolism.

CCAAT/enhancer-binding proteins (C/EBPs): Family of transcription factors (notably C/EBPβ and C/EBPα) that sequentially regulate early and late phases of adipogenic gene activation.

Deubiquitinase: Enzyme that removes ubiquitin tags from proteins, rescuing them from proteasomal degradation and modulating their activity or stability.

AMP-activated protein kinase (AMPK): Cellular energy sensor that inhibits anabolic processes and promotes catabolism, including suppression of adipogenic differentiation.

Flavonoids: Polyphenolic compounds from plant sources that modulate oxidative stress, inflammation and signalling pathways involved in adipogenesis.
