Hyperostosis frontalis interna (HFI) is manifested by the accretion of bone on the inner table of the frontal bone. Despite the vast literature on HFI, ambiguity exists as to its etiology, osteogenesis, demography, and history. This stimulated the…

In this report we examined the effect of tamoxifen upon the nigrostriatal dopaminergic system. Ovariectomized mice were subjected to one of the following treatments: two subcutaneous injections administered on successive days of the sesame oil…

Tamoxifen (10 pg/ml) was infused directly into superfused striatal tissue fragments of ovariectomized rats for a 50 min period. Immediately following the termination of tamoxifen there was a significant increase in dopamine output compared with…

In the present report adult female rats were ovariectomized (OVX) and assigned to one of four treatment conditions. Treatments consisted of administering pellets containing 17 beta-oestradiol (E), tamoxifen (TMX), a combination of TMX and E or no…

There are considerable data suggesting that vasoactive intestinal peptide (VIP) is involved in the regulation of PRL secretion; however, the role and cell of origin of anterior pituitary VIP remain to be determined. Immunocytochemical (ICC) studies…

Studies with the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) animal model of Parkinson's disease have shown the ability of 17 beta-estradiol to protect the nigrostriatal dopaminergic system. This paper reviews the signaling pathways mediating…

This study was undertaken to establish the presence and characteristics of receptors for [D-Trp(6)]LH-RH on the membranes of human ovarian cancer. Specific binding of [I-125, D-Trp(6)]LH-RH was found in 29 of 37 (78.4%) ovarian cancers and in 6 of 11…

The current study examines regulation of CYP7B1, a DHEA 7 alpha-hydroxylase, by sex hormones. Transfection with estrogen receptor alpha and treatment with 17 P-estradiol in human embryonic kidney 293 cells significantly increased CYP7B1 catalytic…

Contractions of rat thoracic aorta to vasopressin WP) are threefold higher in females (F) than in males (M), primarily because nitric oxide (NO) attenuation of contraction is greater in M. To determine the role of the androgen receptor (AR) in this…

Background: VEGF-regulated genes in the cervices of pregnant and non-pregnant rodents (rats and mice) were delineated by DNA microarray and Real Time PCR, after locally altering levels of or action of VEGF using VEGF agents, namely siRNA, VEGF…
