Additionally, to elucidate pathophysiological mechanisms that could explain the relations between MUPS and depression, we investigate the association between a sustained high level of MUPS, and (I) omega (ω)-3 and -6 fatty acid (FA)-status and (II) functional polymorphisms in the promoter region of the serotonin transporter gene (5-HTTLPR).
Antidepressants that block the serotonin transporter, (Slc6a4/SERT), selective serotonin reuptake inhibitors (SSRIs) improve mood in adults but have paradoxical long-term effects when administered during perinatal periods, increasing the risk to develop anxiety and depression.
A deletion/insertion polymorphism within the 5-HT transporter promoter gene (5-HTTLPR) is thought to be associated with disturbed impulse control, anxiety, and depression.
A common regulatory variant (5-HTTLPR) in the human serotonin transporter gene (SLC6A4), resulting in altered transcription and transporter availability, has been associated with vulnerability for affective disorders, including anxiety and depression.
Seasonal variations in mood and behavior (seasonality) and seasonal affective disorder (SAD) have been attributed to seasonal fluctuations in brain serotonin (5-HT). the short (s), as opposed to the long (l), allele of the 5-HT transporter linked polymorphism (5-HTTLPR) has been associated with neuroticism and depression.
Previous studies have identified SLC6A4 and HTR2A associations with SSRI response in patients with depression and 5-HTTLPR (SLC6A4) associations with escitalopram response in ASD.
The present study was conducted to explore whether the polymorphism and methylation status of the serotonin transporter gene (5HTT) promoter region (PR-5HTT) contribute to depression in SLE patients from both genetic and epigenetic perspectives.
Since both posttraumatic stress disorder (PTSD) and depression are associated with disturbances in the serotoninergic system, the aim of the study was to determine the association between severity of PTSD symptoms, serotonin transporter polymorphism (5-HTTLPR) and platelet serotonin (5-HT) concentration, in male combat veterans with PTSD (n = 325), who were subdivided according to presence of comorbid depression.
A number of studies have shown that the presence of short (S) allele of the serotonin transporter-linked polymorphic region (5-HTTLPR) is associated with a higher risk for depression following exposure to stressful life events.
The NET and 5-HT1A polymorphisms appear to have similar effects on hippocampal volume in patients and controls while the 5-HTTLPR polymorphism differentially affects hippocampal volume in the presence of depression.
The aim of this study was to investigate experts' opinions regarding the extent to which the introduction of pretesting for polymorphism of serotonin transporter promoter region (5-HTTLPR) as a routine intervention in clinical practice would lead to better clinical outcomes for depression patients.
Individualization of therapy for depression may be achieved through consideration of the specific associations that patients exhibit between life stress, 5-HTTLPR polymorphism, and depression symptomatology.
Participants who were homozygous for the short allele of 5-HTTLPR or carried a STin2.9 VNTR allele were significantly more likely to have a history of depression.
The 5-HTTLPR short allele (s) has been associated with anxiety-related personality traits and depression, and one study observed an association between the 5-HTTLPR s-allele and SAD and the trait of seasonality.
The findings indicate that ELBW/SGAs carrying the 5-HTTLPR short allele reported increased internalizing problems, particularly depression, during the third and fourth decades of life.
Depression symptoms increased during antiviral treatment; 5-HTTLPR genotype moderated IFN-alpha-induced depression symptoms in both non-Hispanic Caucasians and Hispanic patients, although the opposite risk allele was associated with depression in the two populations.
We recorded the symptomatic profile in 73 in panic disorder patients using observer-rated instruments (Panic Disorder Severity Scale, PDSS; Montgomery-Asberg Depression Rating Scale, MADRS) and hypothesized more severe symptoms in patients carrying the 5-HTTLPR s-allele.
Diabetic patients who had Beck Depression Inventory scores ≥ 14 had experienced significantly more different types of childhood trauma than those with Beck Depression Inventory scores < 14 (P < .001), independent of potential interaction with 5-HTTLPR genotype.
