Project description:Rice, the worldM-bM-^@M-^Ys most important food crop, is attacked by multiple herbivores and pathogens.the rice striped stem borer (SSB) Chilo suppressalis is one of another most important rice insect pests. Here, we use Affymetrix Whole-Genome rice arrays to detect SSB infestation responsive genes. RNA samples from five damaged stems of SSB-challenged 24 h rice plants or five stems from unchallenged plants (for control samples) were used to array analysis. Two replicate biological experiments of SSB treatment rice arrays and one control samples array were peformed.

Project description:The yeast Hsp70 chaperone Ssb interacts with ribosomes and nascent chains to co-translationally assist protein folding. Here, we present a proteome-wide analysis of Hsp70 function during translation, based on in vivo selective ribosome profiling, that reveals mechanistic principles coordinating translation with chaperone-assisted protein folding. Ssb binds most cytosolic, nuclear, and mitochondrial proteins and a subset of ER proteins, supporting its general chaperone function. Position-resolved analysis of Ssb engagement reveals compartment- and protein-specific nascent chain binding profiles that are coordinated by emergence of positively charged peptide stretches enriched in aromatic amino acids. Ssbs’ function is temporally coordinated by RAC but independent from NAC. Analysis of ribosome footprint densities along orfs reveals that ribosomes translate faster at times of Ssb binding. This is coordinated by biases in mRNA secondary structure, and codon usage as well as the action of Ssb, suggesting chaperones may allow higher protein synthesis rates by actively coordinating protein synthesis with co-translational folding.

Project description:Primary Sjögren’s syndrome (pSS) is a systemic autoimmune disease characterized by reduced activity of the exocrine glands (principally the salivary and lacrimal glands) due to chronic lymphocytic infiltration. pSS has been closely associated with an enhanced risk of mucosa-associated lymphoid tissue (MALT) lymphoma. However, the dynamic epigenetic changes in gland cells accompanied with this pathogenesis are not fully understood. In present study, the labial gland (LG) and parotid gland (PG) tissues from two pSS patients with lymphoma were harvested including LG with negative anti-SSA/SSB and LG with positive anti-SSA/SSB at the first diagnosis of pSS, as well as PG with and without lymphoma tissues at the second diagnosis of MALT. ChIP-seq of H3K4/9/27/36/79me3 were performed. This data is benefit to advanced understanding the dynamic development of MALT from pSS, emphasizing the importance of epigenetic alterations in regulating transcription during the pathologic process.
