Withdrawal: Increased expression of fibroblast growth factor 21 (FGF21) during chronic undernutrition causes growth hormone insensitivity in chondrocytes by inducing leptin receptor overlapping transcript (LEPROT) and leptin receptor overlapping transcript-like 1 (LEPROTL1) expression.

Expression of leptin and leptin receptor transcript in ovine corpus luteum

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-pituitary-gonadal axis have been established. Moreover, the direct and local effect of leptin on bovine oocyte maturation and corpus luteum fu...

LEPROT and LEPROTL1 cooperatively decrease hepatic growth hormone action in mice.

Growth hormone (GH) is a major metabolic regulator that functions by stimulating lipolysis, preventing protein catabolism, and decreasing insulin-dependent glucose disposal. Modulation of hepatic sensitivity to GH and the downstream effects on the GH/IGF1 axis are important events in the regulation of metabolism in response to variations in food availability. For example, during periods of redu...

Altered Expression of Epidermal Growth Factor Receptor (EGFR) in Glioma

      EGFR is a key molecule in cancer cells. EGFR signaling was shown to promote tumor cell proliferation and survival, invasion and angiogenesis and mediate resistance to treatment, including ionizing radiation in preclinical models. We extracted proteins from astrocytoma (III and IV) oligodendroglioma(IV) tumors and normal brain tissues and then evaluated the protein purity by Bradford test ...

Detection of leptin and leptin receptor mRNA expression in the bovine t

Leptin receptor mRNA expression in Taleshi ram gonads

Leptin is secreted mainly by fat, which is involved in energy metabolism and reproduction. Leptin and itsreceptor (Ob-R) have been detected in human spermatozoa and testis, thus it can be concluded leptin involves in male physiology. The goal of this study was determination of the presence of leptin receptor mRNA in the ram testis, epididymis and spermatozoa by reverse transcription polymerase ...
