Quantification of the hybridization signals demonstrated a significant increase in expression (+16.5%) between 13:00 h and 19:30 h, with the values at 23:30 h and 09:00 h being similar to that of 19:30 h.

A 2106 bp cDNA, isolated from a human hippocampal cDNA library, contained an open reading frame of 497 amino acids which encodes the beta subunit of the human GlyR. The mature human GlyR beta polypeptide displays 99% amino acid identity with the rat GlyR beta subunit and 48% identity with the human GlyR alpha 1 subunit. Neither [3H]strychnine binding nor glycine-gated currents were detected when the human GlyR beta subunit cDNA was expressed in the human embryonic kidney 293 cell line. However, co-expression of the beta subunit cDNA with the alpha 1 subunit cDNA resulted in expression of functional GlyRs which showed a 4-fold reduction in the EC50 values when compared to alpha 1 homomeric GlyRs. Glycine-gated currents of alpha 1/beta GlyRs were 17-fold less sensitive than homomeric alpha 1 GlyRs to the antagonists picrotoxin, picrotoxinin and picrotin, providing clear evidence that heteromeric alpha 1/beta GlyRs were expressed. The beta subunit appears to play a structural rather than ligand binding role in GlyR function. Fluorescence in situ hybridisation was used to localise the gene encoding the human GlyR beta subunit (GLRB) to chromosome 4q32, a position syntenic with mouse chromosome 3. In situ hybridisation using the human GlyR beta subunit cDNA showed that the murine GlyR beta subunit gene (Glrb) maps to the spastic (spa) locus on mouse chromosome 3 at bands E3-F1. This is consistent with the recent finding that a mutation in the murine GlyR beta subunit causes the spa phenotype. It also raises the possibility that mutations in the human beta subunit gene may cause inherited disorders of the startle response.</p>","PeriodicalId":9159,"journal":{"name":"Brain research.

It is generally accepted that in the male rat this pattern is markedly influenced by androgens secreted by the Leydig cells. Recent findings, however, point to the existence of other non-androgenic testicular factors produced by the Sertoli cells and which regulate in vivo the GH responses to growth hormone releasing hormone (GHRH). The aim of this work was to investigate the role played by non-androgenic testicular factors on hypothalamic somatostatin (SST) and GHRH mRNA levels. Seventy-day-old male Sprague-Dawley rats were used throughout the work. They were divided into five groups: (1) control rats; (2) gonadectomized rats; (3) gonadectomized rats supplemented with exogenous administration of dihydrotestosterone (DHT); (4) ethylene dimethane sulphonate (EDS)-treated rats; (5) EDS-treated rats supplemented with exogenous administration of DHT. EDS is a cytotoxic agent that specifically destroys the Leydig cells. The rats were killed after 15 days of treatment. Hypothalamic SST mRNA levels were determined by Northern blot and by in situ hybridization, and GHRH mRNA levels assessed by Northern blot. We found that selective removal of Leydig cells with EDS greatly reduced the SST mRNA content in the periventricular nucleus of the hypothalamus. These levels were significantly lower than those found in gonadectomized rats. Furthermore, replacement treatment with dihydrotesterone (DHT) did not completely restore SST mRNA levels in EDS-treated rats, contrasting with the complete recovery of SST mRNA levels in gonadectomized rats. On the other hand, gonadectomy and EDS treatment produced a significant reduction in GHRH mRNA levels. DHT administration reversed the action of gonadectomy, but did not restore GHRH mRNA content in EDS-treated rats. These data suggest that, in addition to testosterone, as yet unidentified non-androgenic testicular factors can significantly influence SST and GHRH mRNA levels. This may indicate that non-androgenic testicular factors acting at hypothalamic level may be important in the neuroregulation of GH secretion and in the maintenance of sexual dimorphism in GH secretory pattern.</p>","PeriodicalId":9159,"journal":{"name":"Brain research.
