Cancer progression is accompanied by widespread transcriptional changes and metabolic alterations. While it is widely accepted that the origin of cancer can be traced to the mutations that accumulate over time, relatively recent evidence favors a similarly fundamental role for alterations in the epigenome during tumorigenesis. Changes in epigenetics that arise from post-translational modificati...

This review focuses first on conceptual chaos and different connotations in psychosomatic medicine, then on new perspectives on comorbidity and multimorbidity, especially from epigenetics perspective. Comorbidity is one of the greatest research and clinical challenges to contemporary psychiatry and psychosomatic medicine. Recently altered gene expression due to epigenetic regulation has been im...

A growing area of epigenetics research focuses on changes in gene expression that occur without altering the primary sequence, exclusively based on DNA, RNA, or protein modifications. Epigenetic modifications have been shown to change based on nutrition and environmental factors, and have been implicated in human diseases such as cancer and aging. In some cases, epigenetic changes are heritable...

Epigenetic research aims to understand heritable gene regulation that is not directly encoded in the DNA sequence. Epigenetic mechanisms such as DNA methylation and histone modifications modulate the packaging of the DNA in the nucleus and thereby influence gene expression. Patterns of epigenetic information are faithfully propagated over multiple cell divisions, which makes epigenetic regulati...
