A Graphical summary and B interaction network analysis of differentially expressed genes in smoker buccal mucosa. Different shapes represent the molecular class of the protein. Red and green indicate upregulation and downregulation, respectively, while blue and orange indicate inhibition and activation, respectively. A solid line indicates a direct interaction, a dashed line indicates an indirect interaction, and a dotted line indicates inferred correlation from machine-based learning. An asterisk indicates that multiple identifiers in the dataset file map to a single gene or chemical in the Global Molecular Network
