BGN and Parkinson disease: Figure 7A displays the protein-chemical interaction network between PD and BD. In this analysis, we have used the betweenness of 200 as a parameter do obtain the network from Network Analyst. The dark blue circles represent the highly expressed proteins in this network which are ANKRD1, GATA6, C3. Other than these proteins BGN, LHX9, GPRIN3 are also notable. As far as chemical agents are concerned, Aflatoxin B1, Nickel, Valproic acid, Silicon Dioxide are some of the highly enriched as observed. Figure 7B shows the protein-chemical network between SCZ and PD.
