Papaya (Carica papaya L.) is a typical climacteric fruit, undergoing massive physico-chemical changes during ripening. Although papaya is widely cultivated and consumed, few studies have characterized the variations in metabolism during its ripening process at the proteasome level. Using an integrated approach involving Tandem Mass Tag labeling and liquid chromatography–mass spectrometry analysis, proteomes of papaya fruit at di...
... and diverse subcellular localizations. Among the DEPs, most of the pathogen defense-related proteins were down-regulated, suggesting that disease resistance decreased during the ripening process. The Kyoto Encyclopedia of Genes and Genomes enrichment analysis revealed that various metabolic pathways were significantly altered, particularly in flavonoid and fatty acid metabolisms. The up-regulation of several flavonoid biosynthesis-related proteins may provide more raw materials for pigment biosynthesis, acceler...

LC-MSMS (Label free) was performed to find differential proteins in maternal rat serum exosome between 3 normal pregnant rats and 3 pregnant rats carrying fetuses with spina bifida aperta induced by all-trans retinoic acid (Sigma; 4% [wt/vol] in olive oil; 140 mg/kg body weight by gavage) at pregnant...

Revealing the reproductive mechanism of schistosomes will help to control this disease. In this study, the proteomic profiles of single-sex infected female (SF) worms and bisexual infected mature female (MF) worms of Schistosoma japonicum at 18, 21, 23 and 25 days post infection (dpi) were identified wi...

p85β is a regulatory subunit of phosphatidylinositol 3-kinase. The signaling mechanism of p85β is poorly understood. Quantitative mass spectrometry-based phosphoproteomic analysis was therefore performed to reveal proteins with an altered phosphorylation status upon PIK3R2 depletion in ovarian cancer ce...

DUBs are involved in various pathways and signalling networks by pairing with E3 ubiquitin ligases in protein complexes. In order to test whether OTUD5 associates with an E3 ubiquitin ligase to regulate cell proliferation, the stable Flag-OTUD5/Hep3B cell line was established by transfecting Hep3B cel...
