Genetic Link Found Between Anxiety And Prosocial Behavior
2013-10-16 06:58:29

redOrbit Staff & Wire Reports - Your Universe Online A person’s willingness to volunteer and help others could be influenced by a gene that also impacts his or her level of social anxiety, according to research published in September’s edition of the journal Social Neuroscience. The paper, which the authors believe is the first to describe this particular pathway, explained that prosocial behavior is related to the same gene that predisposes certain men and women to anxiety...

Serotonin Regulating Gene Plays Role In Marriage Emotions
2013-10-08 07:11:26

April Flowers for redOrbit.com - Your Universe Online Why are some couples seemingly fated to have a happy marriage and others end in sorrow? A new study from UC Berkeley and Northwestern University reveals a major clue rests in our DNA. The study, which may be the first to link genetics, emotions and marital satisfaction, shows a gene involved in the regulation of serotonin can predict how much our emotions affect our relationships. “An enduring mystery is, what makes one spouse...

Glowing Molecules Help Scientists Track Serotonin

[ Watch the Video ] John Neumann for redOrbit.com - Your Universe Online Researchers have succeeded in tracking a single protein that regulates the neurotransmitter serotonin, making it possible to study the dynamics of the protein which regulates mood, appetite and sleep, at an unprecedented level of detail, reports David Salisbury of Vanderbilt University. Attempts to understand how these transporters work have been limited by the difficulty of studying their dynamic behavior. The...

Early disruptions in serotonin signaling in the brain may contribute to autism spectrum disorder (ASD), and other "enduring effects on behavior," Vanderbilt University researchers report. Serotonin is a brain chemical that carries signals across the synapse, or gap between nerve cells. The supply of serotonin is regulated by the serotonin transporter (SERT). In 2005, a team of Vanderbilt researchers led by Randy Blakely and James Sutcliffe identified rare genetic variations in children...

Meaningful associations dependent on reliable measures of pre-existing trauma Data in a study published in the Archives of General Psychiatry suggest that certain variants of a gene that helps regulate serotonin (a brain chemical related to mood), may serve as a useful predictor of risk for symptoms related to posttraumatic stress disorder (PTSD) following a trauma. "One of the critical questions surrounding PTSD is why some individuals are at risk for developing the disorder following...

University of Michigan research finds new evidence that our genes play a role in our response to adversity University of Michigan Health System researchers have found new evidence that our genes help determine our susceptibility to depression. Their findings, published online today in the Archives of General Psychiatry, challenge a 2009 study that called the genetic link into question and add new support to earlier research hailed as a medical breakthrough. In the summer of 2003, scientists...

Researchers say they can't link depression to your genetic makeup, but the more bad things that happen to you, the more likely you are to suffer severe depression. Despite progress in risk gene identification for complex diseases, few disorders have proven as resistant to gene identification as psychiatric illnesses. Contrary to a previous report, an analysis of 14 previous studies finds no association between a serotonin transporter gene variation, stressful life events, and an increased...

Contrary to a previous report, an analysis of 14 previous studies does not find an association between a serotonin transporter gene variation, stressful life events, and an increased risk of major depression, according to an article in the June 17 issue of JAMA. The authors did find that the number of stressful life events is associated with depression.Despite progress in risk gene identification for several complex diseases, few disorders have proven as resistant to gene identification as...

Findings Could Lead to More Personalized Alcohol Treatment Methods New research from the University of Virginia Health System could help explain why some alcoholics are more severe drinkers than others.   A UVA team has found strong evidence that the serotonin transporter gene, SLC6A4, plays a significant role in influencing drinking intensity among alcohol-dependent individuals. The study, published in the February 2009 issue of Alcoholism: Clinical & Experimental Research,...

DNA plays a role in the amount of alcohol you drink, researchers say. Among alcohol-dependent (AD) individuals, DNA variations in the brain's serotonergic system influence drinking intensity. Specifically the serotonin transporter gene (SLC6A4) contributes to a person's inclination to drink. Researchers analyzed the associations between 275 AD patients seeking treatment and six variations of SLC6A4. Of the six variations, those who carried two T alleles were found to drink more intensely than...
