The Department of Clinical Research conducts
research on the epidemiology of alcohol use, the effects of alcohol on health and the treatment of alcohol use disorders in Japan, in cooperation with universities and other research institutions. The Department of Education and Information fosters the human capacity to achieve the primary, secondary and tertiary prevention of alcohol-related problems and the dissemination SNX-5422 of information on alcohol. The centre also performs alcohol-related problem prevention activities, government consultations and international collaborative research and personal exchanges, thereby functioning as a central institution for alcohol policy-based medical services and research in Japan.”
“The
insulin-like growth factor-I (IGF-I) is a key regulator of reproductive functions. IGF-I actions are primarily mediated by IGF-IR. The main objective of this research was to evaluate the presence of IGF-I and IGF-I Receptor (IGF-IR) in stallion testicular tissue. The hypotheses of this study were (i) IGF-I and IGF-IR are present in stallion testicular cells including Leydig, Sertoli, and developing germ cells, and (ii) the immunolabelling of IGF-I and IGF-IR varies with age. Testicular tissues from groups of 4 stallions in different developmental ages were used. Rabbit anti-human polyclonal antibodies against IGF-I and IGF-IR were used as primary antibodies for immunohistochemistry and Western blot. At the pre-pubertal and pubertal stages, IGF-I immunolabelling CP-868596 solubility dmso was present in spermatogonia and Leydig cells. At post-pubertal, adult and aged stages, immunolabelling of IGF-I was observed in spermatogenic cells (spermatogonia, spermatocyte, spermatid, and spermatozoa) and Leydig cells. Immunolabelling of IGF-IR was observed in spermatogonia and Leydig cells at the pre-pubertal
stage. The immunolabelling becomes stronger as the age of animals advance through the post-pubertal stage. Strong immunolabelling of IGF-IR was observed in spermatogonia and Leydig cells at post-puberty, adult and aged stallions; and faint labelling was seen in spermatocytes at these ages. Immunolabelling selleck chemicals llc of IGF-I and IGF-IR was not observed in Sertoli cells. In conclusion, IGF-I is localized in equine spermatogenic and Leydig cells, and IGF-IR is present in spermatogonia, spermatocytes and Leydig cells, suggesting that the IGF-I may be involved in equine spermatogenesis and Leydig cell function as a paracrine/autocrine factor.”
“Objective: To review the expression of the glucocorticoid receptor (OR) in anterior pituitary and adrenocortical cells and tumors derived from these tissues as well as factors that may influence its expression.
Methods: We present an overview of the relevant literature, with a focus on data generated from our studies.
