Epigenetic’s is a term that describes everything that happens in the gene expression process that is above the genome. The epigenetic process is typically due to histone modification, CpG island methylation, RNA associated silencing, and some other factors. The process is triggered via cell-to-cell signaling, neighborhood cells sending signals, physiology, and environment. The epigenetic change can be transient, permanent, or heritable. In my chosen paper, the researchers are looking into how the social environment can ‘get into the mind’ in a way that results in psychiatric disorders such as schizophrenia, major depressive disorder (MDD), post-dramatic stress disorder (PTSD), anorexia nervosa, and substance dependence. Even though the review article covers five types of mental disorders, I’m going to focus on schizophrenia and anorexia nervosa. Overtime, research has shown a robust relation between the social environment and the prevalence of mental illness. In large western cities, like NYC, there is a higher frequency in those that have schizophrenia, increased labor stress helps facilitate MDD development, natural disasters have been associated with PTSD, and social and relationship problems help induce the onset of eating disorders. It is also important to note that heritable factors also play a part, and that the resulting mental disorder is thought to occur due to an interaction between the social environment and heritable factors. In a schizophrenia twin study, even
