title: CASE-REPORT Dysregulation of gene expression in a patient with depressive disorder after transient ischemic attack confirmed by a neurophysiological neuromarker.
abstract: The aim of this study was to evaluate dysregulation of gene expression associated with the cellular stress response in a patient with a post-"warning stroke" depressive disorder confirmed by the presence of a neurophysiological neuromarker through the use of quantitative EEG and event-related potentials. The patient was tested for seven genes associated with the stress reaction: HSPA1A, HSPB1, IL6, IL10, CRP, and HSF-1 along with NF-κB, compared to gene expression in health controls. A 54-year-old patient with a past history of schizophrenia (at the age of 20), and of transient ischemic attack (at the age of 53) and depressive disorder confirmed by functional, cognitive, emotional, and affectional diagnostics underwent additional testing for expression of the genes associated with stress response. The expression of genes coding for heat shock protein (HSPA1A, HSPB1), interleukins (IL6, IL10), and C-reactive protein was tested along with factors that regulate their expression. The results of the tests conducted on this patient were compared with 42 healthy control subjects. Diagnostic testing revealed upregulation in expression of these genes, presenting as increased expression of the target genes and of the regulatory genes. A post-"warning stroke" depressive disorder appears to be associated with overexpression of the genes coding for HSP and interleukins. Further research on larger groups of people may provide grounds for treatment modification.
