Leptin May Promote Eosinophilic CRSwNP Progression by Enhancing Eosinophil Chemotaxis and Angiogenesis Under a Type 2 Inflammatory Milieu

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis with nasal polyp (CRSwNP) is a heterogeneous Type 2 inflammatory disease characterized by enhanced eosinophilic infiltration. Both innate and adaptive immunity are involved in the onset and progression of CRSwNP.

Effects of diabetes family history and exercise training on the expression of adiponectin and leptin and their receptors [PDF]

open access: yes, 2009
The daughters of patients with diabetes have reduced insulin sensitivity index (ISI) scores compared with women with no family history of diabetes, but their ISI increase more in response to exercise training(1).

Mapping quantitative trait loci underlying body weight changes that act at different times during high‐fat diet challenge in collaborative cross mice

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Over one billion people worldwide suffer from obesity, and the number is continually rising. Animal models, especially mouse models, are crucial to identifying the genetic components of complex disorders and exploring the potential applications of these genetic findings.

Expression of leptin and its receptor in female breast cancer in relation with selected apoptotic markers.

open access: yesFolia Histochemica et Cytobiologica, 2008
Leptin and its receptor may be engaged in pathogenesis of breast cancer among various human tumors. In vitro investigations showed leptin-mediated escalation of estrogen synthesis and boosted activity of estrogen receptor ERalpha.

Maternal corticotropin-releasing hormone is associated with LEP DNA methylation at birth and in childhood: an epigenome-wide study in Project Viva [PDF]

open access: yes, 2018
BackgroundCorticotropin-releasing hormone (CRH) plays a central role in regulating the secretion of cortisol which controls a wide range of biological processes. Fetuses overexposed to cortisol have increased risks of disease in later life.

Metabolic and biochemical profiling reveals phenotypic heterogeneity in Zucker diabetic fatty rats

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Genetically uniform Zucker Diabetic Fatty (ZDF) rats spontaneously develop four distinct metabolic phenotypes despite identical housing and diet conditions. Each phenotype exhibits unique biomarker signatures encompassing glucose homeostasis, insulin secretion, polyol pathway activation, oxidative stress, inflammatory cytokines, and neurotrophic ...

Fatty acid nitroalkenes ameliorate glucose intolerance and pulmonary hypertension in high-fat diet-induced obesity [PDF]

open access: yes, 2014
Aims Obesity is a risk factor for diabetes and cardiovascular diseases, with the incidence of these disorders becoming epidemic. Pathogenic responses to obesity have been ascribed to adipose tissue (AT) dysfunction that promotes bioactive mediator ...

Acute leptin deficiency, leptin resistance, and the physiologic response to leptin withdrawal [PDF]

open access: yesProceedings of the National Academy of Sciences, 2005
Food restriction and weight loss result in reduced plasma leptin, which is associated with a pleiotropic biologic response. However, because weight loss itself is also associated with changes in numerous other humoral and metabolic signals, it can be difficult to determine the precise features of the biologic response to acute leptin deficiency.

Optimization and verification of high‐fat diet formulation for establishing a rat model of obesity‐related precocious puberty

open access: yesAnimal Models and Experimental Medicine, EarlyView.
We identified 45% HFD as the optimal formulation to establish a juvenile rat model of obesity‐related precocious puberty. It elicits robust phenotypic (early vaginal opening, obesity), histological (advanced ovarian development), and endocrine (elevated HPG axis hormones) alterations, with leptin‐mediated GnRH secretion as a core mechanistic driver ...

Leptin Suppresses Glutamate-Induced Apoptosis Through Regulation of ERK1/2 Signaling Pathways in Rat Primary Astrocytes

open access: yesCellular Physiology and Biochemistry, 2017
Background/Aims: Leptin is a hormone expressed by adipose tissue that regulates body energy homeostasis and weight loss by activating leptin receptors in the hypothalamus. Leptin receptors are also expressed in astrocytes.
