Prothymosin alpha (PTMA) is a small acidic protein abundantly and ubiquitously expressed in mammals and involved in different biological activities. Until now, its specific function in spermatogenesis has never been properly investigated. Recently, t

This study was conducted to verify the effect(s) of melatonin treatment on frog Leydig cells. Morphological observation after melatonin treatment indicates that many frog Leydig cells show degenerative changes (i.e. heterochromatic nuclei, loss of ce

SUMMARY In the present study, we have utilized 17β-estradiol to induce the increase of mast cell number in order to verify the melatonin effect on mast cell accumulation in the frog testicular interstitium. Data obtained from in vivo experiments con

Ethane 1,2-dimethane sulphonate (EDS), a toxin which specifically destroys Leydig cells (LC), has been used to study cellular interactions in the testis of the frog Rana esculenta. Animals received three consecutive EDS injections and were sacrificed

GHRELIN (GHRL) is an acylated peptide that contains 28-amino acids prevalently expressed in the stomach of several species. Specifically, it contributes to energy balance, but some new evidence highlights its role in the regulation of reproductive fu

Melatonin, nocturnally secreted by the pineal gland, regulates a variety of physiological functions, including reproduction. Here, we investigated the evidence of melatonin binding sites in frog tissue (brain, retina, and testis) through saturation a

The effects of gonadectomy and testosterone treatment on the fine structure of the Harderian gland in male and female green frogs were investigated in different periods of the year. Gonadectomy, carried out when the glands are in the lowest secretory

Melatonin content and N-acetyltransferase (NAT) activity were studied in the Harderian gland (HG), retina, pineal gland and serum of the frogRana esculenta over a 12L:12D cycle during October-November. A diurnal pattern of melatonin content was found

Prothymosin alpha (PTMA) is a highly acidic small polypeptide, that is, widely distributed and conserved among mammals. Its possible involvement in male gametogenesis has been mentioned but not clarified yet; in particular, it has been suggested that

SummaryIt is well known that melatonin provokes reproductive alterations in response to changes in hours of daylight in seasonally breeding mammals, exerting a regulatory role at different levels of the hypothalamic–pituitary–gonadal axis. Althou
