White adipose tissue distribution and amount are associated with increased white matter connectivity

Jean-Philippe Thiran, Gabriel Girard, Elda Fischi Gomez, Philipp Johannes Koch

Obesity represents a significant public health concern and is linked to various comorbidities and cognitive impairments. Previous research indicates that elevated body mass index (BMI) is associated with structural changes in white matter (WM). However, a ...

Hippo-YAP/TAZ signalling coordinates adipose plasticity and energy balance by uncoupling leptin expression from fat mass

Johan Auwerx, Jun Yong Kim, Maroun Bou Sleiman, Xiaoxu Li

Adipose tissues serve as an energy reservoir and endocrine organ, yet the mechanisms that coordinate these functions remain elusive. Here, we show that the transcriptional coregulators, YAP and TAZ, uncouple fat mass from leptin levels and regulate adipocy ...

Proliferation-driven mechanical compression induces signalling centre formation during mammalian organ development

Sangwoo Kim

Localized sources of morphogens, called signalling centres, play a fundamental role in coordinating tissue growth and cell fate specification during organogenesis. However, how these signalling centres are established in tissues during embryonic developmen ...

Synergetic Support of Cartilage Homeostasis via Coupled Thermal-Hydrostatic Pressure Stimuli

Yanheng Guo

Cartilage homeostasis, crucial for musculoskeletal function, is orchestrated by interconnected biophysical cues. In healthy cartilage, repetitive compressive loading not only elicits a range of mechanical stimuli but also induces a gradual transient temper ...

Mitochondrial matrix protein LETMD1 maintains thermogenic capacity of brown adipose tissue in male mice

Johan Auwerx, Jun Yong Kim, Maroun Bou Sleiman, Xiaoxu Li

Brown adipose tissue (BAT) has abundant mitochondria with the unique capability of generating heat via uncoupled respiration. Here, Park et al. identify LETMD1 as a mitochondrial matrix protein enriched in brown adipose tissue (BAT) and reveal a crucial ro ...

Cross-anatomical single-cell definition and characterization of human adipose progenitor niche

Radiana Ferrero

Adipose tissue is a key metabolic and highly-dynamic organ whose dysregulation may cause clinical conditions of concern such as obesity and lipodystrophy. Its function varies based on the anatomy, in fact, visceral adipose tissue expansion carries a greate ...

A single-cell-based characterization of mammalian adipose stem and progenitor cell heterogeneity and function

Pernille Yde Rainer

White adipose tissue (WAT) is a cellularly heterogeneous endocrine organ that not only serves as a reservoir for storing and releasing energy but also actively participates in metabolic homeostasis. Given the current rise in obesity and its associated como ...

SIRT7 suppresses energy expenditure and thermogenesis by regulating brown adipose tissue functions in mice

Johan Auwerx

Brown adipose tissue plays a central role in the regulation of the energy balance by expending energy to produce heat. NAD(+)-dependent deacylase sirtuins have widely been recognized as positive regulators of brown adipose tissue thermogenesis. However, he ...

Colchicine stimulates browning via antagonism of GABA receptor B and agonism of? 3-adrenergic receptor in 3T3-L1 white adipocytes

Sulagna Mukherjee

Colchicine has been used for therapeutic purposes and has attracted considerable attention because of its association with tubulin and the inhibition of small tubular polymerization. Although several studies have examined the possible preventive role of co ...

Mammalian adipogenesis regulator (Areg) cells use retinoic acid signalling to be non- and anti-adipogenic in age-dependent manner

Bart Deplancke, Daniel Alpern, Julie Marie Russeil, Maria Litovchenko, Pernille Yde Rainer, Magda Zachara, Radiana Ferrero, Horia Hashimi

Adipose stem and precursor cells (ASPCs) give rise to adipocytes and determine the composition and plasticity of adipose tissue. Recently, several studies have demonstrated that ASPCs partition into at least three distinct cell subpopulations, including th ...

eNAMPT actions through nucleus accumbens NAD + /SIRT1 link increased adiposity with sociability deficits programmed by peripuberty stress

Johan Auwerx, Maria del Carmen Sandi Perez, Olivia Zanoletti, João Pedro de Matos Rodrigues, Simone Astori, Jocelin Grosse, Marie-Isabelle Guillot de Suduiraut, Ioannis Zalachoras, Laia Morato Fornaguera, Sriparna Ghosal

Obesity is frequently associated with impairments in the social domain, and stress at puberty can lead to long-lasting changes in visceral fat deposition and in social behaviors. However, whether stress-induced changes in adipose tissue can affect fat-to-b ...

Trans-anethole Induces Thermogenesis via Activating SERCA/SLN Axis in C2C12 Muscle Cells

Sulagna Mukherjee

Recently, adaptive non-shivering thermogenesis has attracted considerable attention because it can elevate energy expenditure and help treat obesity. Despite the numerous reports related to UCP1-driven thermogenesis, little is known regarding UCP1-independ ...
