The synthesis of many peptides involves several post-translational steps which converts precursors into bioactive peptide. One of these steps results in the α-amidation of the C-terminal from a glycine through a bifunctional enzyme called the peptidylglycine α-amidating monooxygenase (PAM). Although the physiological role of Kisspeptin (KP) in the control of GnRH secretion is well known, the exact molecular form of the bioactive hypothalamic KP remains elusive. By ...

SLDP is where the onset of puberty is more than 2-2.5 standard deviations later than the population mean age and is often familial with strong genetic determinants. The reproductive axis is regulated by gonadotropin-releasing hormone (GnRH), which plays a crucial role in initiating puberty and maintaining fertility through its pulsatile secretion. Disruption in GnRH neuron development or hypothalamic function can lead to DP. UK Biobank data has identified negative health outco...

Objective: In order to investigate the effect of precocity and gonadotropin-releasing hormone analogists (GnRHa) GnRHa treatment on glucose metabolism in female rats, the possible mechanism was studied through the changes of leptin, estrogen, growth hormone, insulin-like growth factor 1 and insulin receptor signal crosslinking pathway.Methods: Forty-eight 2-day-old female Sprague-Dawley (SD) suckers were randomly divided...

Introduction: In healthy adolescents, there is significant inter-individual variation in the timing of peak height velocity (PHV) and the total growth achieved during puberty. The relationship between physical changes of puberty and pubertal growth has been studied previously, but further detail is needed for use in clinical practice, especially where there are worries that early or late pubertal onset will curtail the magnitude of the pubertal growth spurt. O...

Introduction: Numerous studies highlighted a secular trend toward earlier puberty. Several factors, including nutrition and migration, may explain this trend. It is known that girls born small for gestational age (SGA) start puberty at a younger age compared to those born average for gestational age (AGA) and that overweight in childhood may be a risk factor for central precocious puberty (CPP), especially in girls. This study mainly aims to compare the evolut...

Introduction: The pubertal transition is accompanied by voice break in boys. Studies asking men to retrospectively recall their age at voice break report an average age of voice break corresponding to 13.4-14.0 years. However, it may be difficult to remember precisely when your voice broke, and recall bias is quite large. Little is known about voice frequency in boys and girls in relation to pubertal timing.Aim: To asses...
