background: studies have shown that obese individuals are at increased risk of breast cancer development and poorer prognosis. leptin, an adipose tissue-derived hormone, has pro-inflammatory and proliferative effects and a well-established association with several comorbidities of obesity. this study was designed and conducted to compare the serum levels of leptin in patients with malignant and...

Leptin, a peptide hormone secreted by adipocytes in proportion of the amount of energy stored in fat, plays a central role in regulating human energy homeostasis. In addition, leptin plays a significant permissive role in the physiological regulation of several neuroendocrine axes, including the hypothalamic-pituitary-gonadal, -thyroid, -growth hormone, and -adrenal axes. Decreased levels of le...

Leptin is a hormone secreted by the adipocytes that regulates food intake and energy expenditure. It is known that growth hormone (GH) secretion is markedly influenced by body weight, being suppressed in obesity and cachexia, and recent data have demonstrated that GH release is regulated by leptin levels. Although one of the sites of action of leptin is likely to be the hypothalamus, since lept...

Aeromonas salmonicida subsp. is the causative agent of furunculosis, a disease affecting numerous fish species worldwide. It highly pathogenic bacterium for turbot, whose farming production represents an important economic activity in several European countries and China. To better understand response this organism to A. , we conducted RNA-Seq analysis head kidney from experimentally infected u...

The rising global prevalence of obesity presents a diminished quality life and expectancy. Though myriad factors contributes to obesity, one the leading is excessive adipose tissue accumulation increases body’s production leptin satiety hormone resulting in resistance. Leptin resistance results increased vulnerability through improper regulation insulin, decline metabolic functions, decreased s...

BACKGROUND Beta-thalassemia is the most common hematology disease in human and leptin is one of the hormone that produce by adiposities cells. The purpose of this study was to investigate the relationship between serum leptin level and thyroid hormones in children with major beta-thalassemia. MATERIALS AND METHODS This descriptive-cross sectional study was performed on 90 children aged 6-16 y...

objective(s):leptin is a novel and interesting hormone for anyone trying to lose weight, but its effects on male gonad structure in longitudinal study is unknown. the present study was designed to explore morphometrical changes of mouse testicular tissue after long-term administration of leptin. materials and methods:thirty healthy mature male mice were randomly assigned to either control (n=15...
