background: leptin and adiponectin are the two key metabolic hormones secreted from adipocytes to control food intake and energy expenditure. the action of both hormones in regulation of gonadotropin releasing hormone (gnrh) secretion from the hypothalamus is mediated through kisspeptins. kisspeptins are products of kiss-1 gene. leptin and adiponectin are modulators of kiss-1 expression in the ...

Kisspeptins, the products of KiSS-1 gene, have recently emerged as fundamental regulators of reproductive function in different mammalian and, presumably, non-mammalian species. To date, a single form of KiSS-1 has been described in mammals, and recently, in several fish species and Xenopus. We report herein the cloning and characterization of two distinct KiSS-like genes, namely, KiSS-1 and Ki...

در پژوهش کنونی تاثیر شمار نوزادان شیرخوار و شدت شیرخواری بر میزان بیان kiss-1 mrna در هسته آرکوات موش صحرایی شیرده بررسی شد. سی و شش موش صحرایی آبستن، نژاد اسپراگ داولی، به 9 گروه مساوی تقسیم شدند. گروه کنترل شامل موش های صحرایی تخمدان برداری شده و غیرشیرده بود. سه گروه، موش های صحرایی دارای 5، 10 و 15 نوزاد بودند که از نوزادانشان جدا نشدند، و همواره شیرخواری کردند. سه گروه دیگر با 5 نوزاد، که ...

We present our experiments and results for the DCU CNGL participation in the CLEF-IP 2010 Candidate Patent Search Task. Our work applied standard information retrieval (IR) techniques to patent search. In addition, a very simple citation extraction method was applied to improve the results. This was our second consecutive participation in the CLEF-IP tasks. Our experiments in 2009 showed that m...

Kiss-1 has been identified as a putative metastasis suppressor gene in various human malignancies. However, there is little information about its possible role in gastric carcinoma. In this study, we determined whether the Kiss-1 gene negatively regulates MMP-9 expression. cDNA microarray technology was used to identify the genes associated with metastasis by hepatocyte growth factor (HGF) in t...

This study, conducted in the brain of a perciform fish, the European sea bass, aimed at raising antibodies against the precursor of the kisspeptins in order to map the kiss systems and to correlate the expression of kisspeptins, kiss1 and kiss2, with that of kisspeptin receptors (kiss-R1 and kiss-R2). Specific antibodies could be raised against the preprokiss2, but not the preoprokiss1. The dat...

objective(s): the effect of litter size and suckling intensity on the expression of kiss-1 mrna in the arcuate nucleus (arc) of rats were evaluated. materials and methods: thirty two pregnant and four non-lactating ovariectomized (as control group) rats were used in this experiment. lactating rats were allotted to eight equal groups. in three groups, litter size was adjusted to 5, 10, or 15 pup...

During the past decade, the kisspeptin system has been identified in various vertebrates, leading to the discovery of multiple genes encoding both peptides (Kiss) and receptors (Kissr). The investigation of recently published genomes from species of phylogenetic interest, such as a chondrichthyan, the elephant shark, an early sarcopterygian, the coelacanth, a non-teleost actinopterygian, the sp...
