1.
Glucocorticoids induce human glycoprotein hormone alpha-subunit gene expression in the gonadotrope
Sasson R, Luu S, Thackray V, Mellon P
Endocrinology . 2008 Apr; 149(7):3643-55. PMID: 18403486
The human glycoprotein hormone alpha-subunit (alphaGSU) gene is transcriptionally regulated by glucocorticoids in a cell type-specific fashion. In direct contrast to repression of alphaGSU by glucocorticoids in placenta, glucocorticoid receptor...

Orexin A induces GnRH gene expression and secretion from GT1-7 hypothalamic GnRH neurons
Sasson R, Dearth R, White R, Chappell P, Mellon P
Neuroendocrinology . 2006 Dec; 84(6):353-63. PMID: 17192702
Orexin A, a recently discovered hypothalamic peptide, has been shown to have a stimulatory effect on release of gonadotropin-releasing hormone (GnRH) from rat hypothalamic explants in vitro. However, it is...
3.
Steroidogenesis and apoptosis in the mammalian ovary
Amsterdam A, Keren-Tal I, Aharoni D, Dantes A, Land-Bracha A, Rimon E, et al.
Steroids . 2003 Dec; 68(10-13):861-7. PMID: 14667978
Ovarian cell death is an essential process for the homeostasis of ovarian function in human and other mammalian species. It ensures the selection of the dominant follicle and the demise...
4.
Novel genes modulated by FSH in normal and immortalized FSH-responsive cells: new insights into the mechanism of FSH action
Sasson R, Dantes A, Tajima K, Amsterdam A
FASEB J . 2003 Jul; 17(10):1256-66. PMID: 12832290
Follicle-stimulating hormone (FSH) controls the development of follicle-enclosed oocytes in the mammalian ovary by interacting with specific receptors located exclusively on granulosa cells. Its biological activity involves stimulation of intercellular...
5.
Cell-specific regulation of apoptosis by glucocorticoids: implication to their anti-inflammatory action
Amsterdam A, Tajima K, Sasson R
Biochem Pharmacol . 2002 Sep; 64(5-6):843-50. PMID: 12213578
Glucocorticoids play a major role in attenuation of the inflammatory response. These steroid hormones are able to induce apoptosis in cells of the hematopoietic system such as monocytes, macrophages, and...
6.
Stimulation of apoptosis in human granulosa cells from in vitro fertilization patients and its prevention by dexamethasone: involvement of cell contact and bcl-2 expression
Sasson R, Amsterdam A
J Clin Endocrinol Metab . 2002 Jul; 87(7):3441-51. PMID: 12107264
Human granulosa cells obtained from in vitro fertilization patients are highly luteinized, but can still be stimulated by LH/cAMP for production of progesterone. This stimulation involved enhancement of apoptosis. Incubation...
7.
Induction of apoptosis in granulosa cells by TNF alpha and its attenuation by glucocorticoids involve modulation of Bcl-2
Sasson R, Winder N, Kees S, Amsterdam A
Biochem Biophys Res Commun . 2002 Jun; 294(1):51-9. PMID: 12054739
Tumor necrosis factor alpha (TNF alpha) plays a role in mammalian ovarian follicular development, steroidogenesis, ovulation, luteolysis, and atresia, but the exact mechanism of TNF alpha action is not completely...
8.
The anti-inflammatory action of glucocorticoids is mediated by cell type specific regulation of apoptosis
Amsterdam A, Sasson R
Mol Cell Endocrinol . 2002 Jun; 189(1-2):1-9. PMID: 12039060
Glucocorticoids play a major role in attenuation of the inflammatory response. These steroid hormones are able to induce apoptosis in cells of the hematopoietic system such as monocytes, macrophages and...
