Expression of p53 in human adipose tissue correlates positively with FAS and BMI.

Int J Obes (Lond)

December 2024

Division of Pediatric Endocrinology and Diabetology, University Children's Hospital, University of Zurich, Zurich, Switzerland.

Article Synopsis
  • Activation of Fas in adipocytes inhibits the browning process, potentially leading to increased body weight gain in mice, and its expression correlates with higher BMI in humans.
  • The study found that Fas activation decreases energy expenditure through reduced protein levels of p53, a tumor suppressor, in adipocytes.
  • In humans, higher p53 levels in subcutaneous and visceral white adipose tissue were linked to increased BMI, while higher levels in visceral fat were associated with lower insulin sensitivity.

Erythropoietin (EPO) plays a key role in energy metabolism, with EPO receptor (EpoR) expression in white adipose tissue (WAT) mediating its metabolic activity. Here, we show that male mice lacking EpoR in adipose tissue exhibit increased fat mass and susceptibility to diet-induced obesity. Our findings indicate that EpoR is present in WAT, brown adipose tissue, and skeletal muscle.

In adults affected by Major Depressive Disorder (MDD), most findings point to higher electroencephalographic (EEG) theta power during wake compared to healthy controls (HC) as a potential biomarker aiding the diagnostic process or subgrouping for stratified treatment. Besides these group differences, theta power is modulated by time of day, sleep/wake history, and age. Thus, we aimed at assessing if the time of recording alters theta power in teenagers affected by MDD or HC.

Fas (CD95) expression in adipocytes contributes to diet-induced obesity.

Obesity (Silver Spring)

October 2024

Division of Pediatric Endocrinology and Diabetology, University Children's Hospital, University of Zurich, Zurich, Switzerland.

Objective: Induction of browning in white adipose tissue (WAT) increases energy expenditure and may be an attractive target for the treatment of obesity. Since activation of Fas (CD95) induces pathways known to blunt expression of uncoupling protein 1 (UCP1), we hypothesized that Fas expression in adipocytes inhibits WAT browning and thus contributes to the development of obesity.

Methods: Adipocyte-specific Fas knockout (Fas) and control littermate (Fas) mice were fed a regular chow diet or a high-fat diet (HFD) for 20 weeks.

The proneural transcription factor atonal basic helix-loop-helix transcription factor 7 () is expressed in early progenitors in the developing neuroretina. In vertebrates, this is crucial for the development of retinal ganglion cells (RGCs), as mutant animals show an almost complete absence of RGCs, underdeveloped optic nerves, and aberrations in retinal vessel development. Human mutations are rare and result in autosomal recessive optic nerve hypoplasia (ONH) or severe vascular changes, diagnosed as autosomal recessive persistent hyperplasia of the primary vitreous (PHPVAR).

Background: Accelerometers were traditionally worn on the hip to estimate energy expenditure (EE) during physical activity but are increasingly replaced by products worn on the wrist to enhance wear compliance, despite potential compromises in EE estimation accuracy. In the older population, where the prevalence of hearing loss is higher, a new, integrated option may arise. Thus, this study aimed to investigate the accuracy and precision of EE estimates using an accelerometer integrated into a hearing aid and compare its performance with sensors simultaneously worn on the wrist and hip.
