요약Genome-wide association studies (GWAS) aim to understand the genetic component of complex (multifactorial) disease phenotypes, such as addiction and psychiatric disorders, which do not obey the standard Mendelian rules of inheritance. However, the heritability of addiction and psychiatric disorders cannot be explained only by the genetic variants identified by GWAS studies. Both genetic variants and environmental factors play a role in developing complex diseases. The interaction between genetic variants and the environment is translated as epigenetic modifications, which lead to changes to gene function without changes to the underlying DNA sequence itself. One of the most well-studied epigenetic modifications in humans is DNA methylation. It is established and maintained by a specialized group of enzymes called DNA methyltransferases that attach a methyl group to a cytosine nucleotide when it is usually located before guanine (CpG site). DNA methylation changes the phenotypic consequences of the genetic variants. Thus, to fully understand the functional role of potential genetic variants that are associated with addiction and psychiatric disorders it is essential to study the relationship between these genetic variants and DNA methylation of the adjacent CpG sites. Therefore, we conducted three projects to study DNA methylation and its relation to genetic variations in cocaine addiction, schizophrenia, bipolar disorder, and suicidal behavior. My Ph.D. research contributed significantly to our understanding of the complex interaction between genetic variants and the environment by investigating how individuals' epigenetic changes (particularly changes in DNA methylation) are linked to complex disorders, with the goal of developing DNA methylation-based biomarkers. My research discovered specific DNA methylation differences linked to mental health disorders (bipolar disorder, schizophrenia, and suicidal behavior), which helps us understand the biological mechanisms underlying these diseases.
