The unfolded protein response (UPR), which protects cells against accumulation of misfolded proteins in the ER, is induced in several age-associated degenerative diseases. However, sustained UPR activation has negative effects on cellular functions and may worsen disease symptoms. It remains unknown whether and how UPR components can be utilized to counteract chronic ER proteinopathies. We found that promotion of ER-associated degradation (ERAD) through upregulation of ERAD-enhancing α-mannosidase-like proteins (EDEMs) protected against chronic ER proteinopathy without inducing toxicity in a Drosophila model. ERAD activity in the brain decreased with aging, and upregulation of EDEMs suppressed age-dependent behavioral decline and extended the lifespan without affecting the UPR gene expression network. Intriguingly, EDEM mannosidase activity was dispensable for these protective effects. Therefore, upregulation of EDEM function in the ERAD protects against ER proteinopathy in vivo and thus represents a potential therapeutic target for chronic diseases.

Database of Drosophila genetic and genomic information with information about stock collections and fly genetic tools. Gene Ontology (GO) terms are used to describe three attributes of wild-type gene products: their molecular function, the biological processes in which they play a role, and their subcellular location. Additionally, FlyBase accepts data submissions. FlyBase can be searched for genes, alleles, aberrations and other genetic objects, phenotypes, sequences, stocks, images and movies, controlled terms, and Drosophila researchers using the tools available from the "Tools" drop-down menu in the Navigation bar.

More specific versions of JMP are available for statistical analyses, clinical work, and genomics. Features include statistical modeling, data cleanup, automation and scripting, and experimental design.
View all literature mentionsA comprehensive encyclopedia of genomic functional elements in the model organisms C. elegans and D. melanogaster. modENCODE is run as a Research Network and the consortium is formed by 11 primary projects, divided between worm and fly, spanning the domains of gene structure, mRNA and ncRNA expression profiling, transcription factor binding sites, histone modifications and replacement, chromatin structure, DNA replication initiation and timing, and copy number variation. The raw and interpreted data from this project is vetted by a data coordinating center (DCC) to ensure consistency and completeness. The entire modENCODE data corpus is now available on the Amazon Web Services EC2 cloud. What this means is that virtual machines and virtual compute clusters that you run within the EC2 cloud can mount the modENCODE data set in whole or in part. Your software can run analyses against the data files directly without experiencing the long waits and logistics associated with copying the datasets over to your local hardware. You may also view the data using GBrowse, Dataset Search, or download the data via FTP, as well as download pre-release datasets.
