| Objective:To screen the differentially expressed proteins in large B cell lymphoma with different chemosensitivity,
and analyze their types and related signaling pathways to provide the target protein involved chemotherapy sensitivity of lymphoma.Methods:The tumor drug sensitivity test was applied to distinguish high-chemosensitivity and low-chemosensitivity of large B cell
lymphoma tissue for comparative proteomic study. Gene ontology （GO）analysis software was applied to analyze the differentially
expressed protein classification and their relationships.Results:52 differentially expressed proteins between high-chemosensitivity and
low-chemosensitivity of large B cell lymphoma tissue were separated and identified by two-dimensional gel electrophoresis, mass
spectrometry and bioinformatics analysis. The 52 proteins were classified according to the biochemical process and divided into 12 kinds
of protein including metabolic processes related proteins to the most, followed by cell protein. The 52 proteins were classified according
to the signal pathway and belonged to more than 20 signaling pathways, including apoptosis signaling pathway and cell cycle related
pathway. Of the 52 proteins were classified according to molecular function and divided into 9 protein types with the binding related
protein most, followed by the catalytic activity protein, third structural proteins. Of the 52 proteins, protein functional classification
included calcium binding proteins, enzymes, redox enzyme, phosphatase. Based on intracellular localization, 52 proteins were divided
into extracellular proteins, inner proteins, the ribonucleoprotein complex proteins including inner proteins to most, followed by the
ribonucleoprotein complex. According to the signaling network diagram, all the differentially expressed proteins in three complex
network area and four relatively simple network area.Conclusion:Chemotherapy sensitivity of large B cell lymphoma involved changes
of many proteins and a plurality of signal pathway, among there are have complex relations. |
