Central Proteins of Plasma in Response to Low-Level Laser Therapy Involve in Body Hemostasis and Wound Repair

Introduction: low-level laser therapy (lllt) is accompanied by protein expression change in the body. there are many efforts to find a clear relationship between the differentially expressed proteins. this study aims to find the central differentiated expressed proteins of plasma after lllt. methods: six proteins are extracted from a proteomics study and the network including these query proteins plus 100 first neighbors was constructed. the central proteins were determined based on degree value, betweenness centrality, closeness centrality (cc), and stress (the centrality parameters). results: among 106 nodes of the network, 10 proteins were characterized with the most values of degree, betweenness centrality, cc, and stress. these proteins were determined as central proteins in response to lllt in plasma. conclusion: three query proteins, ahsg, fgg, and serpina1, plus 7 first neighbors, namely fga, alb, kng1, fn1, app, timp1, and f5, were identified as central proteins which were dysregulated.
