Evaluation of the leptin receptor in human spermatozoa

open access: yesReproductive Biology and Endocrinology, 2010
Background Leptin, a 167 amino acid peptide hormone, profoundly effects reproduction exerting its biological effects via interaction with the leptin receptor (ObR) which is widely expressed on peripheral tissues.

Estimation of Leptin and Leptin Receptor Concentrations in Seminal Plasma of Primary Infertile Men

open access: yesمجلة كلية الطب, 2017
Background: There are many sources for Leptin secretion, and it is activated by binding with its receptor known as leptin receptor, that play a role in male infertility.

Leptin and Soluble Leptin Receptor in Follicular Fluid [PDF]

open access: yesJournal of Assisted Reproduction and Genetics, 2003
Previous studies suggest that follicular fluid leptin levels predict successful assisted reproduction. The relationship between intrafollicular leptin and the soluble leptin receptor, ovarian hormones, and oocyte quality was examined to determine potential factors contributing to this finding.Follicular fluid leptin, soluble leptin receptor, hormones ...

Associations between serum leptin levels, hyperlipidemia, and cholelithiasis in dogs. [PDF]

open access: yesPLoS ONE, 2017
Leptin and its receptor play several physiological roles in the canine gallbladder, and the dysregulation of leptin might play a role in the pathogenesis of gallbladder diseases such as gallbladder mucocele.

C-Reactive Protein (CRP) and Leptin Receptor in Obesity: Binding of Monomeric CRP to Leptin Receptor

open access: yesFrontiers in Immunology, 2018
While leptin deficiency or dysfunction leads to morbid obesity, obese subjects are characterized paradoxically by hyperleptinemia indicating lack of response to leptin.

Leptin receptor in boar spermatozoa [PDF]

open access: yesInternational Journal of Andrology, 2007
SummaryLeptin is active in both metabolism and reproduction. In fact, it seems to exert an inhibitory action on gonadal functions by reducing testosterone production. The presence of leptin in human and boar seminal plasma and in human spermatozoa has been demonstrated; recently, leptin receptors (Ob‐R) have been localized in human spermatozoa, thus ...

Leptin receptor in the chicken ovary: potential involvement in ovarian dysfunction of ad libitum-fed broiler breeder hens

open access: yesReproductive Biology and Endocrinology, 2004
In hens, the ovarian follicles committed to ovulation are arranged in an ordered follicular hierarchy. In standard broiler breeders hens genetically selected for high growth rate the reproductive function is clearly dysfunctional.

Expression of leptin and leptin receptor transcript in ovine corpus luteum [PDF]

open access: yesIranian Journal of Veterinary Medicine, 2018
Background: Leptin, the product of the obesity (ob) gene, acts as a signaling adipokine for modulating food intake, energy metabolism and reproductive functions in mammals. Leptin’s effects on the reproductive system at various levels of the hypothalamic-

Adipocyte‐Derived Leptolin Enhances Energy Expenditure and Prevents Obesity

open access: yesAdvanced Science, EarlyView.
We identified a novel adipokine, which we named leptolin. In humans, leptolin levels in white adipose tissue were positively correlated with exercise and negatively associated with body mass index. We observed elevated leptolin in serum from athletes and lower leptolin in serum from obese individuals.

Polymorphisms of Leptin (-2548 G/A) and Leptin Receptor (Q223R) Genes in Iranian Women with Breast Cancer

open access: yesInternational Journal of Genomics, 2015
Recent studies have shown that polymorphisms in leptin and leptin receptor genes are associated with increased risk for breast cancer. This study aimed at investigating -2548 G/A polymorphism in leptin gene and Q223R polymorphism in leptin receptor gene ...
