Project description:Paper mulberry as a valuable woody species has a well chilling tolerance. In this study, phosphoproteomic analysis in combination with physiological measurement and mRNA quantification were employed to explore the molecular mechanism of chilling (4 °C) tolerance in paper mulberry. After chilling for 6 hours, there were 427 significant changed phosphoproteins detected in paper mulberry seedlings without obvious physiological injury. When obvious physiological injury occurred after chilling for 48 hours, a total of 611 phosphoproteins were found significantly change at phosphorylation level. According to 9 phosphorylation motifs extracted by Motif-X analysis, MAPKs, CDPKs, CDKs and CKs were considered as the primary upstream protein kinases. Results of GO analysis showed that phosphoproteins were mainly responsible for signal transduction, protein modification and translation during chilling. Additionally, transport and cellular component organization were respectively enriched after chilling for 6 and 48 hours. Based on the analysis of protein-protein interaction network, a protein kinases and phosphatases hub protein was thought as the key of phosphorylation regulation, which probably modulates cross-talk between Ca2+, BR, ABA and ethylene mediated signaling pathways. Together with results, we concluded a schematic chilling tolerance mechanism at phosphorylation level.

Project description:To investigate effects of intake of mulberry leaf extracts on hypercholesterolemia, we performed gene expression profiling on rat liver by microarray analysis. Microarray analysis revealed that mulberry leaf extracts up-regulated the gene expression involved in suppression of cholesterol synthesis and stimulation of innate-adaptive Immunity. Mice were fed a high-cholesterol diet without/with orally administration of mulberry leaf extracts for 4 weeks. Livers were taken for RNA extraction and hybridization on Agilent microarrays.
