项目摘要
The unfolded protein response (UPR) is a large-scale, coordinated response to correct misfolded proteins in
eukaryotes. The diverse set of actions a cell coordinates in parallel (approx. 380 genes in yeast) to alleviate
the various problems that can occur in protein synthesis, folding, glycosylation, and translocation of
membrane-bound and secreted proteins has a large impact on therapeutic protein production and
aggregated protein-related disease. The proposed work will map the biological information flow through the
many genes involved in the response to achieve an understanding of the UPR and identify targets for
altering the response. A biological interaction network of the UPR will be constructed from available
biological interaction data for yeast. Transcriptional, proteomic, metabolomic, and metabolic flux data will be
collected for recombinant yeast producing preinsulin and TNFa with modulated UPR induction. UPRassociated
changes in biological molecule levels detected from the X-omics data will be superimposed onto
the interaction network, revealing the flow of biological information in the UPR. This combination of
information from biological interaction networks and X-omics-scale data will lead to a better understanding of
secreted protein production. In particular, metabolite measurements can indicate possible limitations in
glycosylation pathways, amino acid supply, energetics, redox balance, or lipid synthesis. Transcript and
protein levels may reveal pathways that benefit or detract from high level secretion of protein. From this
information, important biological molecules and interactions can be targeted to improve protein production
and, in humans, identify targets to prevent/treat aggregated-protein related disease. The findings of the
proposed work will be very helpful in understanding the molecules and their interconnections involved in
stress response. This strategy represents a multifaceted approach to understanding a complex biological
response and is consistent with the NIH Building Blocks, Biological Pathways, and Networks roadmap
initiative. Yeast is an attractive commercial producer of therapeutic proteins, but can be limited by low
product yields or poor quality that could be improved by this work. A thorough understanding of the UPR
could have consequences for prevention and treatment of disease known to be related to aggregated
protein, such as Alzheimer's, Type 2 diabetes, and apoptosis-resistant, uncontrolled protein production in
certain cancers.
