Journal ArticleDOI
Expression of neuromedins S and U and their receptors in the hypothalamus and endocrine glands of the rat.
Marcin Rucinski,Agnieszka Ziolkowska,Giuliano Neri,Marcin Trejter,Tomasz Zemleduch,Marianna Tyczewska,Gastone G. Nussdorfer,Ludwik K. Malendowicz +7 more
TL;DR: Semiquantitative real time-PCR showed that in the rat hypothalamus and testis NMS gene expression was markedly higher than that of the NMU gene, while the reverse occurred in the anterior pituitary and thyroid gland.
Journal ArticleDOI
Expression of prepro-ghrelin and related receptor genes in the rat adrenal gland and evidences that ghrelin exerts a potent stimulating effect on corticosterone secretion by cultured rat adrenocortical cells
TL;DR: This study is the first to demonstrate direct stimulating effect of GHREL on corticosterone output by cultured rat adrenocortical cells, which differs from that evoked by ACTH and is not dependent on the presence of functional ACTH receptor.
Journal ArticleDOI
Transcriptome Profile of Rat Adrenal Evoked by Gonadectomy and Testosterone or Estradiol Replacement
Karol Jopek,Piotr Celichowski,Marta Szyszka,Marianna Tyczewska,Paulina Milecka,Ludwik K. Malendowicz,Marcin Rucinski +6 more
TL;DR: Contrary to expectations, in orchiectomized rats, testosterone replacement stimulates expression of numerous genes, mainly those associated with lipids and cholesterol metabolism, however, in ovariectomization animals, estradiol replacement inhibits the expression of genes, especially those involved in intracellular signaling pathways.
Journal ArticleDOI
Expression of estrogen, estrogen related and androgen receptors in adrenal cortex of intact adult male and female rats.
Marcin Trejter,Karol Jopek,Piotr Celichowski,Marianna Tyczewska,Ludwik K. Malendowicz,Marcin Rucinski +5 more
TL;DR: The obtained results suggest that acute steroidogenic effect of estrogens on corticosteroid secretion may be mediated by non-genomic GPR30.
Journal ArticleDOI
Sex-related gene expression profiles in the adrenal cortex in the mature rat: Microarray analysis with emphasis on genes involved in steroidogenesis
Marcin Trejter,Anna Hochol,Marianna Tyczewska,Agnieszka Ziolkowska,Karol Jopek,Marta Szyszka,Ludwik K. Malendowicz,Marcin Rucinski +7 more
TL;DR: Differentially expressed genes which were significantly enriched included genes involved in steroid hormone metabolism, and their expression levels in the ZF/R of adult female rats were significantly higher compared with those in the male rats.
