J Affect Disord 2022; 311:631-636. [PMID: 35623482 PMCID: PMC9842073 DOI: 10.1016/j.jad.2022.05.114] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/18/2022] [Revised: 05/11/2022] [Accepted: 05/19/2022] [Indexed: 01/18/2023]
Abstract
BACKGROUND While the serotonin transporter (SLC6A4) gene, 5-HTTLPR, interacts with the social environment to influence both emotional self-regulation and smoking behavior, less is known about interactions between emotional self-regulation and 5-HTTLPR or their joint influence on tobacco use. Here, we examined such interactions among psychiatric inpatients, the population with the highest rates of smoking. METHODS Participants (506 adults) were psychiatric inpatients at The Menninger Clinic in Houston TX between 2012 and 16. Most were white (89%), male (55%), with a mean age of 32.3 years. Participants completed the Difficulties in Emotional Regulation Scale (DERS) at admission. We examined interactions with smoking among three DERS subscales and 5-HTTLPR, controlling for sex, race and age. RESULTS Smoking rates were higher among those with the 5-HTTPLR L'L' genotype compared to peers carrying an S' allele (47.9% vs. 37.4%, respectively). Among S' allele carrying participants, impulse control difficulties (OR = 1.09; 95%CI: 1.03-1.14) and lack of emotion clarity (OR = 1.06; 95%CI: 1.00-1.11) increased risk for ever using tobacco, while accessing more ways to regulate emotion (OR = 0.95; 95%CI: 0.92-0.99) offered a protective effect against ever using tobacco. Neither demographic nor DERS covariates were associated with using tobacco among the L'L' group. LIMITATIONS This ethnically homogenous sample limits generalizability and using a binary outcome can over-estimate a gene environment interaction effect. CONCLUSIONS Emotional self-regulation exerts a stronger influence on using tobacco among carriers of an S' allele of 5-HTTLPR than peers with the L'L' genotype. Promoting emotional self-regulatory skills may have benefits for preventing tobacco use.

AVPR1A main effect and OXTR-by-environment interplay in individual differences in depression level. Heliyon 2020; 6:e05240. [PMID: 33088973 PMCID: PMC7567928 DOI: 10.1016/j.heliyon.2020.e05240] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2020] [Revised: 07/10/2020] [Accepted: 10/08/2020] [Indexed: 12/30/2022] Open
Abstract
Background Multiple studies of depression indicated a significant role of gene-by-environment interactions; however, they are mainly limited to the examination of modulating effect of recent stressful life events. Other environmental factors occurring at different stages of ante- and postnatal development may affect the association between multiple genes and depression. The study aimed to analyze the main and haplotype-based effect of serotonergic system and HPA-axis gene polymorphisms on depression and to detect gene-by-environment interaction models explaining individual variance in depression in mentally healthy young adults from Russia. Methods Depression score was assessed using Beck Depression Inventory (BDI) in 623 healthy individuals (81% women; 17-25 years) of Caucasian origin (Russians, Tatars, Udmurts) from Russia. The main- and gene-based effects of 12 SNPs in SLC6A4 (5-HTTLPR, rs1042173), HTR2A (rs7322347), OXTR (rs7632287, rs2254298, rs13316193, rs53576, rs2228485, rs237911), AVPR1A (rs3803107, rs1042615), and AVPR1B (rs33911258) genes, and gene-by-environment interactions were tested with linear regression models (PLINK v.1.9) adjusted for multiple comparisons. Results We observed ethnicity-specific main effect of the AVPR1A rs3803107 (P = 0.003; PFDR = 0.047) and gene-based effect of the OXTR gene (Р = 0.005; Pperm = 0.034) on BDI-measured depression, and modifying effect of paternal care on OXTR rs53576 (P = 0.004; PFDR = 0.012) and birth order on OXTR rs237911 (P = 0.006; PFDR = 0.018) association with depression level. Limitations A hypothesis driven candidate gene approach, which examined a limited number of genetic variants in a moderately large sample, was used. Conclusions Our preliminary findings indicate that familial environment may play a permissive role modulating the manifestation of OXTR-based depression variance in mentally healthy subjects.

Abstract
There are many studies on how smoking cigarettes is harmful to health, but research on how smoking cessation improves mental health is insufficient. The purpose of this study was to examine long-term effects of smoking cessation on depressive symptoms, resilience, coping skills, and serotonin levels in Korean adults. This was a longitudinal study that followed up on periodically participants for 2 years after the initial smoking cessation intervention. A total of 164 smokers participated within this study. Of these, 15 maintained smoking cessation for 504.93 ± 182.82 days. On the other hand, 148 participants failed to maintain smoking cessation. Depressive symptoms decreased and resilience increased significantly over 2 years in the 15 abstainers. Smoking cessation, in total, decreased depressive symptoms by 32.9% (p = .015) and also increased resilience by 37.5% (p = .012). Smoking cessation also explained for 9% of total positive interpretation at the 1-year follow-up, and 7.3% of total self-criticism at the 2-year follow-up. Serum serotonin did not change over the course of 2 years in both abstainers and smokers but did decrease in the short-term for those who maintained smoking cessation. Platelet serotonin increased over 6 months among smokers.

Effects of Chronic Inhalation of Electronic Cigarette Vapor Containing Nicotine on Neurotransmitters in the Frontal Cortex and Striatum of C57BL/6 Mice. Front Pharmacol 2019; 10:885. [PMID: 31456684 PMCID: PMC6699083 DOI: 10.3389/fphar.2019.00885] [Citation(s) in RCA: 26] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2019] [Accepted: 07/15/2019] [Indexed: 12/12/2022] Open
Abstract
Electronic (E)-cigarettes are the latest form of nicotine delivery device and are highly popular in the general population. It is currently unknown whether vaping E-cigarettes (E-CIGs) leads to nicotine addiction. Alterations in the levels of the neurotransmitters in the mesocorticolimbic areas have been reported to mediate the initiation and development of nicotine addiction. Therefore, to determine whether E-CIGs activate the same addiction pathways as conventional cigarettes, we investigated for the effects of daily inhalation of nicotine (24 mg/ml)-containing E-CIG vapor for 6 months on the concentrations of these neurotransmitters in the frontal cortex (FC) and striatum (STR) of male C57BL/6 mice as compared to control group that was exposed to air only. We reported here that 6-month E-CIG vapor containing nicotine inhalation decreased dopamine concentration only in the STR. There were no changes in serotonin concentrations in the FC or STR. Chronic E-CIG exposure also increased glutamate concentration in the STR alone, while glutamine concentrations were increased in both the FC and STR. We found that E-CIG exposure also decreased GABA concentration only in the FC. These data suggest that chronic E-CIG use alters homeostasis of several neurotransmitters in the mesocorticolimbic areas, which may result in the development of nicotine dependence in E-CIG users.
