Spinal-bulbar muscle atrophy (SBMA) or also named Kennedy's Disease is caused by a polyglutamine expansion (PolyQ) of the coding region of the androgen receptor (AR). The AR is a ligand-controlled transcription factor and member of the nuclear hormone receptor superfamily. The central
Spinal and bulbar muscular atrophy (SBMA) is a late-onset, progressive neurodegenerative disease linked to a polyglutamine (polyQ) expansion in the androgen receptor (AR). Men affected by SBMA show marked muscle weakness and atrophy, typically emerging midlife. Given the androgen-dependent nature of
Spinal and bulbar muscular atrophy (SBMA), or Kennedy's disease, is an adult-onset lower motor neuron disease caused by the expansion of a trinucleotide CAG repeat encoding a polyglutamine tract within the first exon of the androgen receptor (AR) gene. The testosterone-dependent nuclear accumulation
An in vivo screening assay using intact adult male rats has been evaluated for its ability to detect six antiandrogenic compounds via oral administration. The test compounds included cyproterone acetate (CPA), flutamide (FLUT), p,p'-DDE (DDE), di-n-butyl phthalate (DBP), linuron (LIN), and
The effect of a synthetic steroidal anti-androgen, TZP-4238, on steroid-induced rat prostatic hyperplasia was investigated. Male Wistar rats were divided into four experimental groups. Group 1 consisted of intact controls. The other animals were castrated. The castrated animals were treated for 7
The atrophic effects of a synthetic steroidal anti-androgen, TZP-4238, on the pituitary, prostate and adrenal gland of rats were investigated. Male Sprague-Dawley rats were divided into three experimental groups. Group 1 consisted of controls. Groups 2 and 3 received chlormadinone acetate (CMA) 50
A series of experiments were conducted to investigate the regulation of the primary secretory protein of the canine prostate, arginine esterase, by androgens and/or new antiandrogen under development. In the first experiment, castration decreased (P less than 0.05) prostatic arginine esterase levels
The present in vitro study demonstrates the effect of androgen on thymocyte apoptosis leading to thymic atrophy in the wall lizard, Hemidactylus flaviviridis. Thymocytes collected from castrated lizards were incubated with varying concentrations of dihydrotestosterone (DHT) to observe its effect on
Spinal and bulbar muscular atrophy (SBMA) is an X-linked motoneuron disease due to a CAG triplet-repeat expansion in the androgen receptor (AR) gene, which is translated into an elongated polyglutamine (polyQ) tract in AR protein (ARpolyQ). ARpolyQ toxicity is activated by the AR ligand testosterone
The effects of combined treatment with the antiandrogen, cyproterone acetate, and ethinyl oestradiol on four women with long-standing hidradenitis suppurativa have been investigated. The condition was controlled successfully in all patients with 100 mg/day cyproterone acetate using the reversed
Androgens are suggested to interact with leptin production and with insulin sensitivity in both polycystic ovary syndrome (PCOS) and obesity. The aim of the study was to follow these interactions along with two forms of antiandrogen treatment. Twenty women with PCOS were treated with
The effect of a synthetic steroidal anti-androgen, chlormadinone acetate (CMA), on spontaneous benign prostatic hyperplasia (BPH) in the dog was investigated. Old male beagle dogs (5 to 8 years old) were divided into the following experimental groups: group 1 consisting of BPH controls, and group 2
The effect of a synthetic steroidal anti-androgen, TZP-4238, on spontaneous benign prostatic hyperplasia (BPH) in dogs was investigated. Old male beagle dogs (5-9 years old) were divided into three experimental groups. Group 1 consisted of BPH controls. Groups 2 and 3 received TZP-4238 0.1 mg/kg/day
To investigate the effect of anti-androgens on BPH, Oxendolone (OXD), a pure anti-androgen, was tested in experimentally induced BPH in 17 beagle dogs, alone or in combination with medroxyprogesterone acetate (MPA) which displays both anti-androgenic and anti-estrogenic activity. The relatively
