Project description:In this study, TMT (tandem mass tag)-labeled quantitative protein technology combined with LC-MS/MS (liquid chromatography-mass spectrometry/mass spectrometry) was used to isolate and identify the proteins of the hybrid bamboo (Bambusa pervariabilis × Dendrocalamopsis grandis) and the bamboo inoculated with the pathogenic fungi Arthrinium phaeospermum. A total of 3320 unique peptide fragments were identified after inoculation with either A. phaeospermum or sterile water, and 1791 proteins were quantified. A total of 102 differentially expressed proteins were obtained, of which 66 differential proteins were upregulated and 36 downregulated in the treatment group. Annotation and enrichment analysis of these peptides and proteins using the GO (Gene Ontology) and KEGG (Kyoto Encyclopedia of Genes and Genomes) databases with bioinformatics software showed that the differentially expressed protein functional annotation items were mainly concentrated on biological processes and cell components. The LC-PRM/MS (liquid chromatography-parallel reaction monitoring/mass spectrometry) quantitative analysis technique was used to quantitatively analyze 11 differential candidate proteins obtained by TMT combined with LC-MS/MS. The up-down trend of 10 differential proteins in the PRM results was consistent with that of the TMT quantitative analysis. The coincidence rate of the two results was 91%, which confirmed the reliability of the proteomic results. Therefore, the differentially expressed proteins and signaling pathways discovered here may be the further concern for the bamboo-pathogen interaction studies.
Project description:BackgroundThe carpal tunnel syndrome (CTS) caused by atypical infection is a therapeutic and diagnostic challenge. Atypical clinical presentations often lead to misdiagnosis and incorrect therapy.Case presentationThis article reports a case of deep infection leading to CTS manifestations. A male patient was admitted for numbness and pain of the left hand. Left carpal tunnel release, median nerve decompression with synovial resection were performed. Inflamed synovium and effusion were submitted for bacterial culture and metagenomic next-generation sequencing (mNGS). The etiologic agent was identified as Arthrinium phaeospermum and the patient recovered after surgical debridement and 10 months of therapy.ConclusionsDiagnosis of mycotic infection of the hand is challenging as the presentation is similar to other conditions. mNGS is presented as a valuable diagnostic adjunct for uncovering unusual infectious agents.
