This study investigated the effects of genetic predispositions to SCZ and BD on current dietary habits among older adults with lifestyle-related diseases, potentially offering insights for preventive mental health strategies. A cohort of 730 older patients who were diagnosed with or suspected of having lifestyle-related diseases was assessed for eight current dietary categories: miso soup, Japanese tea, green and yellow vegetables, light-colored vegetables, fruits, pickles, meats, and soybeans. Polygenic risk scores (PRSs) for the risk of SCZ and BD, including BD types I and II, the shared risk of SCZ and BD, and the differentiation of SCZ from BD, were calculated utilizing data from large-scale genome-wide association studies (GWASs). Our findings revealed that PRSs for SCZ and BD risk significantly influenced specific dietary habits, particularly decreased consumption of nutrient-rich foods such as light-colored vegetables (SCZ, R<sup>2</sup> = 0.0096, p = 3.54 × 10<sup>-3</sup>; BD, R<sup>2</sup> = 0.0074, p = 9.09 × 10<sup>-3</sup>) and soybeans (SCZ, R<sup>2</sup> = 0.0061, p = 0.019; BD, R<sup>2</sup> = 0.014, p = 8.38 × 10<sup>-4</sup>). Notable differences in dietary effects were observed between PRSs for BD I and BD II, with a more pronounced impact associated with BD I (e.g., light-colored vegetables, BD I, R<sup>2</sup> = 0.015, p = 3.11 × 10<sup>-4</sup>; BD II, p > 0.05). Moreover, shared genetic factors for SCZ and BD were correlated with lower intakes of miso soup (R<sup>2</sup> = 0.013, p = 1.21 × 10<sup>-3</sup>), Japanese tea (R<sup>2</sup> = 0.0092, p = 5.59 × 10<sup>-3</sup>), light-colored vegetables (R<sup>2</sup> = 0.010, p = 2.92 × 10<sup>-3</sup>), and soybeans (R<sup>2</sup> = 0.014, p = 3.13 × 10<sup>-4</sup>).

The existing drugs are ineffective for approximately 30% of patients, so it is urgent to develop new antidepressant drugs with novel mechanisms.

We then utilized the drug-treated CSDS mice paradigm to segregate and gain differential protein groups of CSDS versus CON (CSDS<sub>CON</sub>), imipramine (IMI)-treated versus CSDS (IMI<sub>CSDS</sub>), and NOR-treated versus CSDS (NOR<sub>CSDS</sub>) from the prefrontal cortex. These protein expression alterations were first analyzed by ANOVA with p < 0.05. The protein cluster 1 and cluster 3, in which the pattern of protein levels similar to the mood pattern, showed enrichment in functions and localizations related to mitochondrion, ribosome and synapses.

The aim of the present study was therefore to identify the impact of central LEAP2 on the ability of alcohol to activate the mesolimbic dopamine system and to define its ability to control alcohol intake. These experiments revealed that central LEAP2 (i.e. into the third ventricle) prevented the ability of alcohol to cause locomotor stimulation in male mice, suppressed the memory of alcohol reward and attenuated the dopamine release in the nucleus accumbens caused by alcohol. Moreover, central LEAP2 reduced alcohol consumption in both male and female rats exposed to alcohol for 6 weeks before treatment. However, the serum levels of LEAP2 were similar between high- and low- alcohol-consuming (male) rats. Furthermore, central LEAP2 lowered the food intake in the alcohol-consuming male rats and reduced the body weight in the females.

Targeting negative symptoms may thus hold promise for the treatment of CHR and RO patients. Building from previous findings we examined whether the catechol-O-methyltransferase (COMT) Val<sup>158</sup>Met functional polymorphism and fasting peripheral proline concentration predicts the severity of negative symptoms experienced by adolescents and young adults at CHR or those with RO. As hypothesized, the interaction between fasting plasma proline and COMT predicted negative symptoms, as measured via the Scale for the Assessment of Negative Symptoms (SANS) total (n = 50, β = 0.066, adjusted p = 0.007) and global severity scores (n = 50, coefficient = 0.026, adjusted p = 0.003): Higher proline was beneficial for Val/Val subjects, but detrimental to those with the Met allele. In a secondary analysis, the COMT x proline interaction also predicted symptoms measured via the Clinical Assessment Interview for Negative Symptoms (CAINS) total scores (n = 50, β-coefficient = 0.035, adjusted p = 0.044), although this result did not reach the Benjamini-Hochberg's threshold for significance. Further, there was a trend towards significance for an association with social and interpersonal function (Global Functioning-Social, coefficient = -0.005, adjusted p = 0.055). Negative symptoms are intractable and largely unaddressed by current medications. This study further supports a relationship between peripheral proline and COMT influencing negative symptoms such as anhedonia, in young CHR individuals and those with RO. That higher proline has converse effects on symptoms by COMT may have implications for the development of therapeutics to intervene early and specifically target the interaction pathway.</p>","PeriodicalId":23278,"journal":{"name":"Translational Psychiatry","volume":null,"pages":null},"PeriodicalIF":5.8,"publicationDate":"2024-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11447206/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142366639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are two prominent features: Harm Avoidance (HA) and Incompleteness (INC). Previous resting-state studies reported abnormally elevated connectivity between prefrontal cortical (PFC) and subcortical regions (thalamus, striatum) in OCD participants. Yet, little is known about the white matter (WM) structural abnormalities in these connections. Using brain parcellation and segmentation, whole brain tractography, and Neurite Orientation Dispersion and Density Imaging (NODDI), we aimed to characterize WM structural abnormalities in OCD vs. healthy controls and determine the extent to which NODDI indices of these connections were associated with subthreshold-threshold HA, INC and overall OCD symptom severity across all participants. Four PFC regions were segmented: ventral medial (vmPFC), ventrolateral (vlPFC), dorsomedial (dmPFC), and dorsolateral (dlPFC). NODDI Neurite Density (NDI) and Orientation Dispersion (ODI) indices of WM structure were extracted from connections between these PFC regions and the thalamus (42 OCD, 44 healthy controls, mean age[SD] = 23.65[4.25]y, 63.9% female) and striatum (38 OCD, 41 healthy controls, mean age[SD] = 23.59[4.27]y, 64.5% female). Multivariate analyses of covariance revealed no between-group differences in these indices. Multivariate regression models revealed that greater NDI in vmPFC-thalamus, greater NDI and ODI in vmPFC-striatum, and greater NDI in dmPFC-thalamus connections were associated with greater INC severity (Q ≤ 0.032). These findings highlight the utility of NODDI in the examination of WM structure in OCD, provide valuable insights into specific WM alterations underlying dimensional INC, and can facilitate the development of customized treatments for OCD individuals with treatment-resistant symptoms.</p>","PeriodicalId":23278,"journal":{"name":"Translational Psychiatry","volume":null,"pages":null},"PeriodicalIF":5.8,"publicationDate":"2024-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11447092/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142366610","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
