Non-Coding RNA Gene Expression in Psychiatric Disorders (PsiRNA26)
Gene Expression Analysis of Non-coding RNAs in Psychiatric Disorders
This study aims to investigate whether certain non-coding RNAs, which are molecules involved in the regulation of gene activity, are altered in people with psychiatric disorders such as schizophrenia, bipolar disorder, major depression, panic disorder and obsessive-compulsive disorder. Researchers will compare the levels of these molecules in patients who have never received psychiatric medication or who have been free from treatment for at least six months with those found in healthy volunteers. The study will also evaluate whether the expression of these non-coding RNAs changes after approximately five months of standard psychiatric treatment.
Blood samples collected during routine clinical care will be used to measure the expression levels of selected non-coding RNAs using real-time PCR (RT-PCR), a laboratory technique that analyzes gene expression. The study does not assign specific treatments, and all therapies will be prescribed according to standard clinical practice.
The main question the study is trying to answer is whether changes in non-coding RNA expression may serve as biological markers for psychiatric disorders and whether these markers may help monitor the effects of treatment over time. The findings may improve understanding of the biological mechanisms involved in major psychiatric illnesses and support the future development of more accurate diagnostic and therapeutic tools.
