In this context, there are many non-coding RNAs that can be used for this purpose in liquid biopsies. Out of these, microRNAs have been extensively studied. However, there has been an increase of interest in studying long non-coding RNAs, piwi interacting RNAs, circular RNAs, and other small non-coding RNAs.

Recent evidence suggests that gene x environment interaction plays a vital role in suicidal behavior. In this paper, we critically evaluate the association between adolescent suicidal behavior and epigenetic modifications, including DNA methylation, histone modification, and non-coding RNAs, as well as epigenetic-based treatment options. It was noted that the prevalence of suicidal behavior in adolescents varied by age and sex and the presence of psychiatric disorders. Childhood adversity was closely associated with suicidal behavior. Studies show that alterations in epigenetic modifications may increase the risk of suicidal behavior independent of mental illnesses.
