Promising studies suggest that defects in synaptic plasticity detected in schizophrenia may be linked to neurodevelopmental and neurodegenerative abnormalities and contribute to disease-associated cognitive impairment. We aimed to clarify the role of the synaptic plasticity regulatory proteins, nerve growth factor (NGF) and its receptor (NGFR) in the(More)
Schizophrenia is a severe psychiatric disease with inflammatory component. Several studies indicated the increased blood levels of proinflammatory interleukin-6 cytokine in schizophrenia. However, only limited studies explored the relationship between excess production and genetic variations of this cytokine in schizophrenia, and the results were(More)
Defects in synaptic plasticity play a key role in pathophysiology of schizophrenia. Pathomechanisms responsible for synaptic plasticity alterations in schizophrenia are very complicated and not well defined. Transcription factor c-Fos plays an important role in regulation of synaptic plasticity. In the present study we evaluated the association of rs7101(More)
Alterations in neuronal plasticity and immune system play a key role in pathogenesis of schizophrenia. Identification of genetic factors contributing to these alterations will significantly encourage elucidation of molecular etiopathomechanisms of this disorder. Transcription factors c-Fos, c-Jun, and Ier5 are the important regulators of neuronal plasticity(More)
Transcription factors c-Fos, c-Jun, and Ier5 are important regulators of neuronal plasticity and immune response. In the present work, several single nucleotide polymorphisms of the genes that encode c-Fos-,c-Jun-, and Ier5 (FOS, JUN, and IER5, respectively) were investigated for potential association with schizophrenia. DNA samples obtained from patients(More)
Epidemiologic, clinical and experimental data indicates that a majority of brain disorders including schizophrenia (SCZ), posttraumatic stress disorder (PTSD), and ischemic stroke (IS) are multifactorial disorders with strong and complex genetic component. Identification of all genetic variations associated with these disorders may sufficiently contribute(More)
Schizophrenia (SCZ) is a multifactorial chronic and disabling mental disease. The specific genetic variants contributing to disease complex phenotype are largely unknown. Growing amount of evidence suggested that aberrant synaptic connectivity contributes to SCZ pathogenesis. From this point of view, complexin-2, a presynaptic regulatory protein, represents(More)
Background. Breast cancer is one of the most common cancers in women worldwide. The germline mutations of the BRCA1 and BRCA2 genes are the most significant and well characterized genetic risk factors for hereditary breast cancer. Intensive research in the last decades has demonstrated that the incidence of mutations varies widely among different(More)
