Deciphering the skeletal interoceptive circuitry to control bone homeostasis

BMEMat, EarlyView.
This review introduces the skeletal interoceptive circuitry, covering the ascending signals from bone tissues to the brain (sensors), the central neural circuits that integrate this information and dispatch commands (CPU), and the descending pathways that regulate bone homeostasis (effectors).

Anticontractile effect of perivascular adipose tissue and leptin are reduced in hypertension

Frontiers in Pharmacology, 2012
Leptin causes vasodilatation both by endothelium-dependent and -independent mechanisms. Leptin is synthetized by perivascular adipose tissue (PVAT). The hypothesis of this study is that a decrease of leptin production in PVAT of spontaneously rats (SHR ...

Impact of Menstrual Cycle and Oral Contraceptives on Haematological and Inflammatory Biomarkers in Highly Trained Female Athletes

Drug Testing and Analysis, EarlyView.
In highly trained female athletes, haematological and inflammatory biomarkers were found to be independent of menstrual cycle phase, but oral contraceptive use increased transferrin, reticulocyte count and triglycerides and decreased interleukin‐6.

Psychobiological Exercise Response: A Pilot Investigation of a Laboratory Exercise Assessment Paradigm Among Young Women With Eating Disorders

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Compulsive exercise is a common feature of eating disorders (EDs) but understanding of factors that drive this symptom remains limited. This pilot trial evaluated psychobiological response to in‐laboratory exercise among females (14–22 years) with and without restrictive eating pathology.

Leptin Promotes the Expression of Pro-inflammatory Mediator Genes but Does Not Alter Osteoclastogenesis and Early Stage Differentiation of Osteoblasts

Journal of Physiological Investigation
Leptin, a hormone secreted by adipose tissue, plays a pivotal role in maintaining energy metabolism and bone quality. Dysregulation of leptin can lead to the development of various pathological conditions.

Decreased leptin concentration in neonates is associated with enhanced postnatal growth during the first year

Kaohsiung Journal of Medical Sciences, 2012
Leptin regulates maternal metabolism and fetal growth by reducing food intake and increasing energy expenditure, particularly during the third trimester.

Systemic aging fuels heart failure: Molecular mechanisms and therapeutic avenues

ESC Heart Failure, Volume 12, Issue 2, Page 1059-1080, April 2025.
Abstract Systemic aging influences various physiological processes and contributes to structural and functional decline in cardiac tissue. These alterations include an increased incidence of left ventricular hypertrophy, a decline in left ventricular diastolic function, left atrial dilation, atrial fibrillation, myocardial fibrosis and cardiac ...

Multilevel regulation of leptin storage, turnover, and secretion by feeding and insulin in rat adipose tissue

Journal of Lipid Research, 2006
The mechanisms of the increased serum leptin in response to feeding are poorly understood. Therefore, we used metabolic labeling to directly assess leptin biosynthesis, secretion, and turnover in adipose tissue from 14 h-starved compared with fed 12–14 ...

Commonalities of platelet dysfunction in heart failure with preserved ejection fraction and underlying comorbidities

ESC Heart Failure, Volume 12, Issue 2, Page 1013-1028, April 2025.
Abstract Heart failure with preserved ejection fraction (HFpEF) is characterized by a lack of a specific targeted treatment and a complex, partially unexplored pathophysiology. Common comorbidities associated with HFpEF are hypertension, atrial fibrillation, obesity and diabetes.

Differential modulation of arcuate nucleus and mesolimbic gene expression levels by central leptin in rats on short-term high-fat high-sugar diet.

PLoS ONE, 2014
ObjectiveLeptin resistance is a common hallmark of obesity. Rats on a free-choice high-fat high-sugar (fcHFHS) diet are resistant to peripherally administered leptin. The aim of this study was to investigate feeding responses to central leptin as well as
