RP4::Mu3A-mediated in vivo cloning and transfer of a chlorobiphenyl catabolic pathway
, Microbiology, Vol: 142, Pages: 3282-3293Chromosomal DNA fragments encoding the ability to utilize biphenyl as sole carbon source (Bph+) were mobilized by means of plasmid RP4::Mu3A from strain JB1 (tentatively identified as Burkholderia sp.) to Alcaligenes eutrophus CH34 at a frequency of 10(-3) per transferred plasmid. The mobilized DNA integrated into the recipient chromosome or was recovered as catabolic prime plasmids. Three Bph+ prime plasmids were transferred from A. eutrophus to Escherichia coli and back to A. eutrophus without modification of the phenotype. The transferred Bph+ DNA segments allowed metabolism of biphenyl, 2-, 3- and 4-chlorobiphenyl, and diphenylmethane. Genes involved in biphenyl degradation were identified on the prime plasmids by DNA-DNA hybridization and by gene cloning. Bph+ prime plasmids were transferred to Burkholderia cepacia, Pseudomonas aeruginosa, Comamonas testosteroni and A. eutrophus and the catabolic genes were expressed in those hosts. Transfer of the plasmid to the 3-chlorobenzoate-degrading bacterium Pseudomonas sp. B13 allowed the recipient to mineralize 3-chlorobiphenyl. Other catabolic prime plasmids were obtained from JB1 by selection on m-hydroxybenzoate and tyrosine as carbon sources. 16S rRNA sequence data demonstrated that the in vivo transfer of bph was achieved between bacteria belonging to two different branches of the beta-Proteobacteria.

The cerebellum: a model system for studying GABA-A receptor diversity
, Neuropharmacology, Vol: 35, Pages: 1139-1160, ISSN: 0028-3908The basic unsolved questions concerning GABAA receptors are: "How many receptor subtypes exist?", "What subtypes are used by which types of neuron and where are they located on the cell?", and "What are the functions of the different subtypes?" As described in this Review, the cerebellum is an ideal vertebrate brain region for investigating these issues.

Characterization of a cerebellar granule cell-specific gene encoding the gamma-aminobutyric acid type A receptor alpha 6 subunit
, J Neurochem, Vol: 67, Pages: 907-916, ISSN: 0022-3042The alpha 6 subunit of gamma-aminobutyric type A receptors is a marker for cerebellar granule cells and is an attractive candidate to study cell-specific gene expression in the brain. The mouse alpha 6 subunit gene has nine exons and spans approximately 14 kb. The largest intron (intron 8) is approximately 7 kb. For a minority of mRNAs, a missplice of the first exon was identified that disrupts the signal peptide and most likely results in the production of nonfunctional protein. The gene is transcribed from a TATA-less promoter that uses multiple start sites. Using transgenic mice, it was found that the proximal 0.5 kb of the rat alpha 6 gene upstream region confers expression on a beta-galactosidase reporter gene. One founder gave rise to a line with cerebellar granule cell-specific expression, although expression varied with lobule region. Other founders had ectopic but neuron-specific expression, with beta-galactosidase found in cerebellar Purkinje cells, neocortex, thalamus, hippocampus, caudate-putamen, and inferior colliculi. Thus, we have defined a region containing the basal promoter of the alpha 6 subunit gene and that confers neuron-specific expression.

Blunted furosemide action on cerebellar GABA-A receptors in ANT rats selectively bred for high alcohol sensitivity
, Neuropharmacology, Vol: 35, Pages: 1493-1502, ISSN: 0028-3908Furosemide specifically reverses the inhibition by gamma-aminobutyric acid (GABA) of t-[35S]-butylbicyclophosphorothionate ([35S]TBPS) binding and increases the basal [35S]TBPS binding to the cerebellar granule cell layer GABAA receptors. For the selectivity of furosemide, an interplay between GABAA receptor alpha 6 and beta 2 or beta 3 subunits is needed. We have now investigated the furosemide sensitivity of cerebellar [35S]TBPS binding in the alcohol-sensitive (ANT) rat line that harbors a pharmacologically critical point mutation in the alpha 6 subunit [alpha 6 (Q1000)], increasing benzodiazepine affinity of the normally insensitive alpha 6-containing receptors. ANT receptors were less efficiently affected by furosemide, while a normal GABAA receptor antagonism was observed with a specific GABAA receptor antagonist SR 95531. Reduced [3H]muscimol binding in ANT samples and small alterations in situ hybridization signals for alpha 1, alpha 6, beta 2, beta 3, gamma 2 and delta subunit mRNAs failed to correlate with impaired cerebellar furosemide efficacy in individual animals. The alpha 6 (q100) ANT mutation was not responsible for the reduced efficacy of furosemide in the ANT rat line, as judged from the potent furosemide antagonism in recombinant ANT-type alpha 6 (Q100)beta 3 gamma 2 receptors. This data suggest that presence of a novel abnormality in the structure and/or expression of alpha 6 subunit-containing GABAA receptors in the ANT rat line.

Gonadotrophin surge attenuating factor suppresses progesterone augmentation of GnRH priming
, Journal of Clinical Endocrinology & Metabolism, Vol: 81, Pages: 1454-1459We investigated the effects of gonadotropin surge-attenuating factor (GnSAF), inhibin, and follistatin on GnRH self-priming and its augmentation by progesterone. Two GnRH challenges, 60 min apart, were administered to rat pituitary monolayers after 90-min exposure to medium alone (control), progesterone, GnSAF, inhibin, or follistatin. Inhibin-stripped follicular fluid from superovulated women was used as a source of GnSAF bioactivity. Under control conditions, the greater response to the second GnRH challenge (peak 2, 9.2 +/- 2.1; peak 1, 4.4 +/- 0.9 ng LH/mL; P < 0.01) demonstrated GnRH self-priming. None of the treatments significantly altered the first LH peak. Progesterone markedly increased GnRH self-priming (peak 2, 12.6 +/- 2.5 ng LH/mL; P < 0.01). However, GnSAF and RU486 significantly reduced GnRH self-priming (peak 2, 4.6 +/- 0.9 and 5.6 +/- 1.6 ng LH/mL, respectively; P < 0.01). The augmentation of self-priming induced by progesterone was completely abolished by coincubation with either GnSAF or RU486 (peak 2, 7.5 +/- 1.6 and 4.3 +/- 0.9 ng LH/mL, respectively; P < 0.01). Neither inhibin nor follistatin had any effect on GnRH self-priming or its augmentation by progesterone. The actions of RU486 in the presence and absence of progesterone demonstrate a nonprogestagenic effect of RU486 on the gonadotropes. In conclusion, the suppression of GnRH self-priming, with or without progesterone augmentation, supports the hypothesis that GnSAF acts by maintaining the pituitary in an unprimed state of reduced responsiveness to GnRH.

The effects of steroidal and non-steroidal ovarian factors on the pituitary responsiveness to gonadotrophin surge attenuating factor.
, Journal of Endocrinology, Vol: 150, Pages: 413-422Primary pituitary cultures from adult female rats were used to investigate the effects of steroidal (oestradiol and progesterone) and non-steroidal (inhibin, follistatin) ovarian hormones on the suppressive actions of the ovarian factor gonadotrophin surge-attenuating factor (GnSAF) in the control of gonadotrophin secretion. The source of GnSAF was a chromatographic preparation from follicular fluid containing four distinct protein bands as resolved on SDS-PAGE. Oestradiol and progesterone added alone had no effect on gonadotrophin secretion but had a wide range of effects on the suppression of both LH and FSH secretion caused by the non-steroidal factors. Oestradiol, progesterone and oestradiol+progesterone enhanced the suppressive actions of GnSAF on GnRH-induced LH secretion (causing 19.3 +/- 5.2% (P < 0.05), 41.9 +/- 3.4% (P < 0.001) and 32.2 +/- 5.3% (P < 0.001) greater suppression than GnSAF alone). Progesterone and oestradiol+progesterone completely abolished the suppression of basal FSH secretion caused by inhibin (causing 157.1 +/- 22.2%, P < 0.001, and 160.9 +/- 11.3%, P < 0.001, stimulation compared with inhibin alone). Separately the steroids had no effect on the suppression of gonadotrophin secretion caused by follistatin. However, in combination, oestradiol+progesterone potentiated the suppressive actions of follistatin on GnRH-induced LH secretion causing 29.9 +/- 5.3% (P < 0.05) greater suppression than follistatin alone. In combination, high-dose follistatin and GnSAF caused 31.1 +/- 6.5% (P < 0.01) greater suppression than GnSAF alone. Thus in combination high-dose follistatin and GnSAF have additive effects on the suppression of GnRH-induced LH secretion. Recombinant human inhibin and GnSAF added in combination had little further effect compared with either alone suggesting that they may have a similar mechanism of action at the pituitary level. These results demonstrate that while FSH secretion in vitro is mainly controlled b
