Minor satellite DNA, found at Mus musculus centromeres, is not present in the genome of the Asian mouse Mus caroli. This repetitive sequence family is speculated to have a role in centromere function by providing an array of binding sites for the centromere-associated protein CENP-B. The apparent absence of CENP-B binding sites in the M. caroli genome poses(More)
Estrogen increases serotonin transporter (SERT) mRNA and binding sites in female rat brain. In order to determine whether changes in SERT are gender- and steroid-specific we have now carried out studies on adult male Wistar rats which were either intact or castrated (under halothane anesthesia) and injected with arachis oil, estradiol benzoate (EB),(More)
The aim of the present study was to determine the effect of estradiol-17 beta (E2), in its positive feedback mode for gonadotropin release, on the serotonin transporter (SERT) in female rat brain. Levels of SERT mRNA were determined by in situ hybridization and SERT-binding sites were measured by quantitative [3H]paroxetine receptor autoradiography. The(More)
Sex steroids exert potent effects on mood and mental state in the human. Our previous experimental findings in female rats suggest that these effects may be mediated, in part, by the action of estrogen on the 5-hydroxytryptamine2A receptor (5-HT(2A)R) and serotonin transporter (SERT) in brain. Here we review our recent findings on the effect of acute(More)
1. Sex steroid hormones exert profound effects on mood and mental state. Thus, in women, oestrogen is thought to protect against depression and delay the onset of schizophrenia and Alzheimer's disease. 2. Our studies in the female rat show that oestradiol, in its positive feedback mode for gonadotrophin release, increases the expression of genes for the(More)
The pseudoautosomal region (PAR) is a segment of shared homology between the sex chromosomes. Here we report additional probes for this region of the mouse genome. Genetic and fluorescence in situ hybridization analyses indicate that one probe, PAR-4, hybridizes to the pseudoautosomal telomere and a minor locus at the telomere of chromosome 9 and that a PCR(More)
Single-case methodology, using cross-lagged panel correlations, was applied to study the order of change in mood, cognition and cortisol concentration in eight in-patients with a diagnosis of major, endogenous depression. Daily measures included: two visual analogue scales measuring depressed mood and general feeling of unwellness; cortisol concentration in(More)
The bed nucleus of the stria terminalis (BNST) in rodents contains arginine vasopressin (AVP) neurons which project to the lateral septum (LS) and habenula (LH) and are thought to be important for social recognition or memory. In previous studies we demonstrated that AVP immunoreactivity in the LS and LH is absent in the hypogonadal (hpg) mouse and that AVP(More)
The endocrine responses to Luteinizing Hormone Releasing Hormone (LHRH) of eight drug-free males with mania were determined. Basal levels of Luteinizing Hormone (LH) and the plasma levels following injection of LHRH were elevated in patients compared with controls; Follicle Stimulating Hormone (FSH) and testosterone were not different. Elevated levels of LH(More)
Steroids have potent actions on the brain which can be categorized as; (i) fast (approximately ms-s), (ii) intermediate (h-days), (iii) long-term reversible (days-weeks) and (iv) long-term irreversible. Here attention is focussed on the intermediate and long-term reversible effects of steroids with emphasis on glucocorticoids and oestrogen. Glucocorticoid(More)
