Decoding Human Placental Cellular and Molecular Responses to Obesity and Fetal Growth

Advanced Science, EarlyView.
Women with obesity often deliver large‐for‐gestational‐age (LGA) infants. Single‐nucleus RNA sequencing of term placenta reveals that hypoxia and TNF‐α signaling in syncytiotrophoblasts are featured in maternal obesity, but inflammatory signatures in Hofbauer cells and response to lipid or carbohydrate metabolism in fibroblasts are specific to LGA.

Mutations in the Human Leptin and Leptin Receptor Genes as Models of Serum Leptin Receptor Regulation [PDF]

Diabetes, 2002
A part of serum Ob leptin, an adipocyte-secreted peptide, is bound to a soluble Ob receptor (sObR). Immunoreactive sObR was measured in 125 lean or obese control subjects (group 1), 18 individuals with a mutation in the leptin gene impairing leptin secretion (group 2), and 10 individuals with a mutation in the ObR gene, leading to production of a ...

PTG‐Dependent Glycogen Metabolic Dysfunction Drives Impaired Adipose Browning: A Novel Mechanism Linking PM2.5 to Metabolic Disorders

Advanced Science, EarlyView.
This study provides the first evidence that PM2.5 impairs iWAT browning via PTG‐mediated glycogen metabolism disruption, which is initiated by ADRB3 inhibition and subsequently triggers VEGFB upregulation. It thereby delineates the ADRB3‐PTG‐VEGFB axis as central to PM2.5‐induced metabolic dysfunction and identifies adipose glycogen metabolism as a ...

Label‐Free Leukocyte Biophysical Profiling Using Impedance‐Deformability Cytometry for Rapid Cardiovascular Risk Stratification

Advanced Science, EarlyView.
This study presents an impedance‐based single‐cell profiling platform that quantifies the electrical and mechanical properties of neutrophils across in vitro, in vivo, and clinical samples. The approach reveals distinct biophysical alterations associated with type 2 diabetes (T2DM) and cardiovascular complications, suggesting its potential utility for ...

Integrin β3 Orchestrates Hepatic Steatosis via a Novel CD36‐Dependent Lipid Uptake Complex

Advanced Science, EarlyView.
In MASH, ITGB3 recruits LYN and drives its ubiquitin‐proteasomal degradation via phosphorylation. This relieves DHHC5 inhibition, enabling ITGB3/DHHC5/CD36 complex assembly to enhance CD36 palmitoylation and fatty acid uptake, thereby exacerbating disease. Targeting ITGB3 blocks this pathogenic axis and ameliorates MASH.

A Simplified Three‐Tailed N‐Alkyl Phosphoramidate Lipid Platform Enables Inguinal Adipose‐Accumulated mRNA Delivery for Anti‐Obesity Therapy

Advanced Science, EarlyView.
This study develops an mRNA therapy encoding a long‐acting GLP‐1/FGF21 fusion protein. A three‐tailed ionizable lipid engineered three‐component lipid nanoparticle delivers the mRNA to inguinal adipose tissue. In obese mice, this targeted, dual‐hormone treatment potently reduces body weight, fat mass, presenting a localized strategy for metabolic ...

Leptin as a Key between Obesity and Cardiovascular Disease

Journal of Obesity & Metabolic Syndrome, 2020
Obesity increases the risk of cardiovascular disease through various influencing factors. Leptin, which is predominantly secreted by adipose tissue, regulates satiety homeostasis and energy balance, and influences cardiovascular functions directly and ...

Leptin and leptin receptor polymorphisms and recurrent pregnancy loss [PDF]

Journal of Perinatology, 2013
Leptin signaling is important in the establishment of pregnancy. We sought to determine if single nucleotide polymorphisms (SNPs) in the leptin and leptin receptor genes are associated with idiopathic recurrent pregnancy loss (RPL).We conducted a case-control study with cases defined as women with idiopathic RPL and controls as parous women without ...

Immunoreactivities of PPARγ2, leptin and leptin receptor in oviduct of Chinese brown frog during breeding period and pre-hibernation

European Journal of Histochemistry, 2014
The Chinese brown frog (Rana dybowskii) is a special amphibian with one unique physiological phenomenon, which is that its oviduct expands prior to hibernation, instead of during the breeding period.
