Effects of explosions of different intensities on cortical response threshold (CRT) and activities of succinic dehydrogenase (SDH) and acetylcholinesterase (AchE) in the inner ear were studied on 37 guinea pigs. The results revealed various degrees of cochlear damages due to different doses of explosions, and also a negative correlation between hearing loss and the enzyme activities in both TTS and PTS. The significance of the results is discussed.

Chromosomal region 11q22-q23 is a frequent target for deletion during the development of many solid tumour types, including breast, ovary, cervix, stomach, bladder carcinomas and melanoma. One of the most commonly deleted subregions contains the SDHD gene, which encodes the small subunit of cytochrome b (cybS) in mitochondrial complex II (succinate-ubiquinone oxidoreductase). Germline mutations in SDHD cause hereditary paraganglioma type 1 (PGL1), and suggest a tumour suppressor role for cybS. We present a high-resolution physical map spanning SDHD, covered by 19 YACs and 20 BACs. An approximate 1.1-Mb gene-rich region around SDHD is spanned by a complete BAC contig. Twenty-six new STSs are developed from the BAC clone ends. In addition to the discovery and characterisation of 15 new simple tandem repeat polymorphisms, we provide integrated positional information for 33 ESTs and known genes, including KIAA1391, POU2AF1 (OBF1), PPP2R1B, CRYAB, HSPB2, DLAT, IL-18, PTPS, KIAA0781 and KAIA4591, which is mapped by NotI site cloning. We describe full-length transcript sequence for PPP2R1B, encoding the protein phosphatase 2A regulatory subunit A beta isoform. We also discover a processed pseudogene for USA-CYP, a cyclophilin associated with U4/U6 snRPNs, and a novel gene, DDP2, encoding a mitochondrial protein similar to the X-linked deafness-dystonia protein, which is juxtaposed 5'-to-5' to SDHD. This map will help assess this gene-rich region in PGL and in other common tumours.

Corynebacterium glutamicum grows aerobically on a variety of carbohydrates and organic acids as single or combined sources of carbon and energy. To characterize the citrate utilization in C. glutamicum on a genomewide scale, a comparative analysis was carried out by combining transcriptome and proteome analysis. In cells grown on citrate, transcriptome analysis revealed highest expression changes for two different citrate-uptake systems encoded by citM and tctCBA, whereas genes encoding uptake systems for the glucose- (ptsG), sucrose- (ptsS) and fructose- (ptsF) specific PTS components and permeases for gluconate (gntP) and glutamate (gluC) displayed decreased mRNA levels in citrate-grown cells. This pattern was also observed when cells grown in Luria-Bertani (LB) medium plus citrate were compared with cells grown in LB medium, indicating some kind of catabolite repression. Genes encoding enzymes of the tricarboxylic acid cycle (aconitase, succinyl-CoA synthetase, succinate dehydrogenase and fumarase), malic enzyme, PEP carboxykinase, gluconeogenic glyceraldehyde-3-phosphate dehydrogenase and ATP synthase displayed increased expression in cells grown on citrate. Accordingly, proteome analysis revealed elevated protein levels of these enzymes and showed a good correlation with the mRNA levels. In conclusion, this study revealed the citrate stimulon in C. glutamicum and the regulated central metabolic genes when grown on citrate.
