question:
Cu/Zn-superoxide dismutase is misfolded in familial and sporadic amyotrophic lateral sclerosis, but it is not clear how this triggers endoplasmic reticulum (ER) stress or other pathogenic processes. Here, we demonstrate that mutant SOD1 (mSOD1) is predominantly found in the cytoplasm in neuronal cells. Furthermore, we show that mSOD1 inhibits secretory protein transport from the ER to Golgi apparatus. ER-Golgi transport is linked to ER stress, Golgi fragmentation and axonal transport and we also show that inhibition of ER-Golgi trafficking preceded ER stress, Golgi fragmentation, protein aggregation and apoptosis in cells expressing mSOD1. Restoration of ER-Golgi transport by over-expression of coatomer coat protein II subunit Sar1 protected against inclusion formation and apoptosis, thus linking dysfunction in ER-Golgi transport to cellular pathology. These findings thus link several cellular events in amyotrophic lateral sclerosis into a single mechanism occurring early in mSOD1 expressing cells.
answer:
Mutant SOD1 inhibits ER-Golgi transport in amyotrophic lateral sclerosis.

question:
The hygiene hypothesis is thought to be a significant contributor to the growing incidence of inflammatory bowel disease (IBD) around the world, although the evidence for specific factors that underlie the hygiene hypothesis in IBD is unclear. We aimed to systematically review the literature to determine which hygiene-related factors are associated with the development of IBD. Publications identified from a broad based MEDLINE and Current Contents search between 1966 and 2007 on key terms relevant to the 'hygiene hypothesis' and IBD including H pylori exposure, helminths, cold chain hypothesis, measles infection and vaccination, antibiotic use, breastfeeding, family size, sibship, urban upbringing, day care attendance and domestic hygiene were reviewed. The literature suggests that the hygiene hypothesis and its association with decreased microbial exposure in childhood probably plays an important role in the development of IBD, although the strength of the supporting data for each of the factors varies considerably. The most promising factors that may potentially be associated with development of IBD include H pylori exposure, helminths, breastfeeding and sibship. However, the vast majority of studies in this area are plagued by serious methodological shortcomings, particularly the reliance on retrospective recall of information making it difficult to truly ascertain the importance of a 'hygiene hypothesis' in IBD. The 'hygiene hypothesis' in IBD is an important area of research that may give clues to the aetiology of this disease. Directions for future research are recommended.
answer:
Hygiene hypothesis in inflammatory bowel disease: a critical review of the literature.

question:
Substitute Teacher Despite the relative ease of genome manipulation in S. cerevisiae, researchers are always looking to learn still more convenient and rapid methods for substituting yeast promoters. Replacing a gene's native promoter with a heterolo-gous promoter of choice allows regulated expression and simplifies the task of discerning functional relevance. Although a host of clever chromosomal insertion strategies have been described over the years, the advent of the S. cerevisiae Genome Deletion Project provides an incredible resource for a further streamlined workflow. The strategy, explained by Liko et al. on p. 728 is appealingly simple. The genome deletion project resulted in a collection of strains in which a single ORF is replaced with a kanamycin resistance module. Although the purpose of the collection is to have a comprehensive resource of essentially all possible knockouts, the authors point out that for almost any given yeast promoter of interest there will be a strain in which the ORF imm...
answer:
Using the yeast gene deletion collection to customize gene expression.
