Methylation of the Oxytocin, Oxytocin Receptor, and Vasopressin Gene Promoters in Tobacco Use Disorder during Cessation.

Introduction: Vasopressin (AVP) and oxytocin (OT) exert sex-specific effects on social pair bonding and stress reactions while also influencing craving in substance use disorders. In this regard, intranasal oxytocin (OT) and AVP antagonists present potential treatments for tobacco use disorder (TUD). Since transcription of both hormones is also regulated by gene methylation, we hypothesized sex-specific changes in methylation levels of the AVP, OT, and OT receptor (OXTR) gene during nicotine withdrawal.

Therapeutic Use of Cannabinoids in Critically Ill Patients: A Survey of Intensive Care Physicians in Germany.

In the course of the legalization of cannabis for therapeutic purposes in Germany, there has been growing interest in the medical use of cannabinoids. To date, the therapeutic potential of cannabinoids for the treatment of critically ill patients has not been explored. This study aims to understand better whether and how frequently cannabinoids have been administered to critically ill patients in recent years.

Cytosine methylation in GABA B1 receptor identifies alcohol-related changes for men in blood and brain tissues.

Aims: Alcohol use alters the reward signaling processes contributing to the development of addiction. We studied the effects of alcohol use disorder (AUD) on brain regions and blood of deceased women and men to examine sex-dependent differences in epigenetic changes associated with AUD. We investigated the effects of alcohol use on the gene promoter methylation of GABBR1 coding for GABAB receptor subunit 1 in blood and brain.

Chronic Voluntary Alcohol Consumption Alters Promoter Methylation and Expression of and .

Alcohol abuse accounts for 3.3 million deaths annually, rendering it a global health issue. Recently, fibroblast growth factor 2 (FGF-2) and its target, fibroblast growth factor receptor 1 (FGFR1), were discovered to positively regulate alcohol-drinking behaviors in mice.

Comparing DRD2 Promoter Methylation Between Blood and Brain in Alcohol Dependence.

Aims: The dopamine receptor D2 (DRD2) is substantially involved in several forms of addiction. In addition to genetic polymorphisms, epigenetic mechanisms have emerged as an important means of regulation. Previously, DRD2 hypo- and hyper-methylation have been observed in alcohol use disorder (AUD).
