Thyroid hormone and seasonal rhythmicity

Frontiers in Endocrinology, 2014
Living organisms show seasonality in a wide array of functions such as reproduction, fattening, hibernation and migration. At temperate latitudes, changes in photoperiod maintain the alignment of annual rhythms with predictable changes in the environment.

Temporal dynamics and diagnostic utility of kisspeptin and neudesin across the menstrual cycle in polycystic ovary syndrome

Middle East Fertility Society Journal
Background Polycystic Ovary Syndrome (PCOS) is a complex endocrine disorder that is characterized by neuroendocrine dysfunction. While gonadotropin dysregulation is well established, the roles of neuropeptides, such as kisspeptin and neudesin, remain ...

Increased expression of kisspeptin and GnRH forms in the brain of scombroid fish during final ovarian maturation and ovulation

Reproductive Biology and Endocrinology, 2012
Background Kisspeptins (Kiss) are prime players in the control of reproductive function through their regulation of gonadotropin-releasing hormone (GnRH) expression in the brain.

Hyperalgesic Activity of Kisspeptin in Mice

Molecular Pain, 2011
Background: Kisspeptin is a neuropeptide known for its role in the hypothalamic regulation of the reproductive axis. Following the recent description of kisspeptin and its 7-TM receptor, GPR54, in the dorsal root ganglia and dorsal horns of the spinal cord, we examined the role of kisspeptin in the regulation of pain sensitivity in mice.

Reproduction, Smell and Neurodevelopmental disorders: Genetic defects in different hypogonadotropic hypogonadal syndromes.

Frontiers in Endocrinology, 2014
The neuroendocrine control of reproduction in mammals is governed by a neural hypothalamic network of nearly 1500 gonadotropin-releasing hormone (GnRH) secreting neurons that modulate the activity of the reproductive axis across life.

The metastasis suppressor gene KiSS-1 encodes kisspeptins, the natural ligands of the orphan G protein-coupled receptor GPR54

, 2001
Natural peptides displaying agonist activity on the orphan G protein-coupled receptor GPR54 were isolated from human placenta. These 54-, 14,- and 13-amino acid peptides, with a common RF-amide C terminus, derive from the product of KiSS-1, a metastasis ...

Altered expression of kisspeptin, dynorphin, and related neuropeptides in polycystic ovary syndrome: A cross-sectional study

International Journal of Reproductive BioMedicine
Background: Since kisspeptin (KISS1) in the hypothalamus is affected by the inhibitory effect of dynorphin, it raises questions about the controlled balance of these 2 neuropeptides in women with and without polycystic ovary syndrome (PCOS).

Kisspeptin-10 is a potent stimulator of LH and increases pulse frequency in men [PDF]

, 2011
Kisspeptins stimulate GnRH and thus gonadotropin secretion. Kisspeptin-10 is the minimal kisspeptin sequence with full intrinsic bioactivity, but it has not been studied in ...
