With the aim of identifying key proteins that play a role in the disorder tinnitus, interactions between proteins involved in thalamo-amygdala signaling under conditions of normal hearing (NH), acoustic stimulation (AS), and tinnitus (Tin) were studied. Three gene lists compiled from the GeneCards database using keywords were characterized by analyses of overlap, protein-protein interaction (PPI) networks, and by protein-enrichment analysis. Key proteins were selected on the basis of the degree and combined score value of the corresponding PPI network. In the NH process, BDNF, CASP3, and PVALB were identified as high-degree proteins (HDPs). In the AS process, BDNF, PVALB, and DLG4 are the top three HDPs; in the Tin process, these are BDNF, APP, and TNF. In the Tin process, key proteins appear that differ pre- and postsynaptically from those detectable in NH or AS. The glucocorticoid receptor NR3C1 and its interaction with FKBP5, a glucocorticoid receptor-induced co-chaperone, appear to be of particular importance for the emotional aspects of tinnitus. In tinnitus, the HDPs, together with their high-score interaction proteins, indicate processes of chronic neurodegeneration and of changes in transcription, intercellular communication, and in the survival and growth of neurons.
