ÖZET

Epigenetik, DNA'nın nükleotid dizisinde herhangi bir değişim olmaksızın gen işlevinde kalıtsal olarak gerçekleşen değişikliklerin incelenmesi olarak tanımlanmaktadır. Hatalı epigenetik mekanizmalar, bazı hastalıklarda doğrudan rol oynamaktadır. Epigenetik düzenlenmenin depresyon, şizofreni, madde bağımlılığı, bilişsel işlev bozuklukları gibi ruhsal bozukluklarda ve nörogenezis, nöronal plastisite, öğrenme ve bellekte rol oynadığına dair çok sayıda veri bulunmaktadır. Bu derlemede, epigenetik mekanizmalar ve bu mekanizmaların psikiyatrik hastalıkların gelişimindeki rolü tartışıldı.

ABSTRACT

Epigenetics is defined as the study of heritable changes of gene function that occur without a change in the nucleotide sequence of DNA. Aberrant epigenetic mechanisms have been directly implicated in certain human diseases. There is much evidence that epigenetic regulation is involved in neurogenesis, neuronal plasticity, learning and memory, and in psychiatric disorders such as depression, addiction, schizophrenia, and cognitive dysfunction. In this review, the epigenetics mechanisms and their role in the development of psychiatric disorders were discussed.
