background ghrelin, a 28 amino acid peptide, is effective in control of appetite and body weight. acylated ghrelin peptide is the active form of this peptide which plays a major role in the body’s energy balance. objectives this study aimed to investigate the possible effect (s) of intensive resistance exercise on acylated ghrelin, growth hormone, glucose, insulin, and cortisol plasma levels. p...

administering growth hormone increases growth rate of cultured fish. the aim of this study was isolation and synthesize of persian sturgeon gh cdna. the total rna was extracted from pituitary gland of persian sturgeon and cdna was synthesized. the full-length cdna sequence of persian sturgeon contains a 645 nucleotide open reading frame, which encoding a 214 amino acid residues. the position of...

Pro-vasopressin and pro-oxytocin are prohormones processed in the neurointermediate lobe pituitary to form the biologically active peptide hormones, arginine vasopressin (AVP) and oxytocin. Neurointermediate lobe pituitaries from normal (+/+), heterozygous (+/-), PC2-Null (-/-), PC1/3-Null and oxytocin-Null mice were analyzed by SELDI-TOF mass spectroscopy for the peptide hormone products, AVP,...

The CLE (CLAVATA3/Endosperm surrounding region-related) peptide family is one of the best-studied secreted peptide families in plants. Accumulated data have revealed that CLE genes play vital roles on stem cell homeostasis in different types of meristems. Additionally, CLE genes have been found to perform various biological roles in plant growth and development, and in response to environmental...

Peptide hormones and neuropeptides are packaged and stored in a specialized intracellular organelle called the dense core vesicle. It remains elusive how peptide cargoes are correctly sorted. In the present study, we show that a highly conserved Golgi-localized protein named HID-1 acts to prevent mis-sorting of peptide cargoes to lysosomes for degradation via a PtdIns3P-dependent trafficking pa...

Various ketogenic diet (KD) therapies, including classic KD, medium chain triglyceride administration, low glycemic index treatment, and a modified Atkins diet, have been suggested as useful in patients affected by pharmacoresistant epilepsy. A common goal of these approaches is to achieve an adequate decrease in the plasma glucose level combined with ketogenesis, in order to mimic the metaboli...

The barnacle Balanus amphitrite is a globally distributed marine crustacean and has been used as a model species for intertidal ecology and biofouling studies. Its life cycle consists of seven planktonic larval stages followed by a sessile juvenile/adult stage. The transitional processes between larval stages and juveniles are crucial for barnacle development and recruitment. Although some stud...
