JOURNAL OF ENVIRONMENTAL AND PUBLIC HEALTH 2023; 2023:6767410. [PMID: 36864897 PMCID: PMC9974243 DOI: 10.1155/2023/6767410] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/26/2022] [Revised: 10/10/2022] [Accepted: 01/24/2023] [Indexed: 02/23/2023]
Abstract
Objective The aim of the study is to analyze the correlation between high myopia susceptibility and Ras protein-specific guanine nucleotide-releasing factor-1(RASGRF1) gene polymorphism among college students in Zhejiang. Methods A stratified whole-group sampling method was used to select 218 cases of college students in Zhejiang who met the inclusion and exclusion criteria from January, 2019, to December, 2021, and they were divided into 77 cases (154 eyes) in the high myopia group and 141 cases (282 eyes) in the medium-low myopia group according to the degree of myopia, and 109 cases of college volunteers without myopia from the same period of medical examination in the region were included in the control group. The single nucleotide polymorphisms (SNPs) located in functional regions were selected by searching the literature and genetic databases, and the base sequences of rs939658, rs4778879, and rs8033417 loci were obtained by genotyping candidate SNPs using multiplex ligase detection reaction technique. The cardinality test was used to compare the differences in genotype frequency distribution of each locus of the RASGRF1 gene between the high myopia group and the low to moderate myopia group and the control group. Results The genotype frequencies and allele frequencies of the RASGRF1 gene rs939658 locus in the high myopia group compared with the moderate-low myopia group and the control group were not statistically significant (P > 0.05). The genotype frequencies and allele frequencies of the rs4778879 locus of the RASGRF1 gene were compared among the three groups, and the differences were not statistically significant (P > 0.05). The genotype frequency and allele frequency of the rs8033417 locus of the RASGRF1 gene differed significantly among the three groups (P < 0.05). Conclusion The polymorphism of the rs8033417 locus of the RASGRF1 gene was significantly correlated with the susceptibility of high myopia among college students in Zhejiang.

Reproducing the dopamine pathophysiology of schizophrenia and approaches to ameliorate it: a translational imaging study with ketamine. Mol Psychiatry 2021; 26:2562-2576. [PMID: 32382134 PMCID: PMC8440182 DOI: 10.1038/s41380-020-0740-6] [Citation(s) in RCA: 56] [Impact Index Per Article: 18.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/01/2019] [Revised: 04/06/2020] [Accepted: 04/17/2020] [Indexed: 12/14/2022]
Abstract
Patients with schizophrenia show increased striatal dopamine synthesis capacity in imaging studies. The mechanism underlying this is unclear but may be due to N-methyl-D-aspartate receptor (NMDAR) hypofunction and parvalbumin (PV) neuronal dysfunction leading to disinhibition of mesostriatal dopamine neurons. Here, we develop a translational mouse model of the dopamine pathophysiology seen in schizophrenia and test approaches to reverse the dopamine changes. Mice were treated with sub-chronic ketamine (30 mg/kg) or saline and then received in vivo positron emission tomography of striatal dopamine synthesis capacity, analogous to measures used in patients. Locomotor activity was measured using the open-field test. In vivo cell-type-specific chemogenetic approaches and pharmacological interventions were used to manipulate neuronal excitability. Immunohistochemistry and RNA sequencing were used to investigate molecular mechanisms. Sub-chronic ketamine increased striatal dopamine synthesis capacity (Cohen's d = 2.5) and locomotor activity. These effects were countered by inhibition of midbrain dopamine neurons, and by activation of PV interneurons in pre-limbic cortex and ventral subiculum of the hippocampus. Sub-chronic ketamine reduced PV expression in these cortical and hippocampal regions. Pharmacological intervention with SEP-363856, a novel psychotropic agent with agonism at trace amine receptor 1 (TAAR1) and 5-HT1A receptors but no appreciable action at dopamine D2 receptors, significantly reduced the ketamine-induced increase in dopamine synthesis capacity. These results show that sub-chronic ketamine treatment in mice mimics the dopaminergic alterations in patients with psychosis, that this requires activation of midbrain dopamine neurons, and can be ameliorated by activating PV interneurons and by a TAAR1/5-HT1A agonist. This identifies novel therapeutic approaches for targeting presynaptic dopamine dysfunction in patients with schizophrenia and effects of ketamine relevant to its therapeutic use for treating major depression.

Abstract
Effects of Vortioxetine on the expression of brain-derived neurotrophic factor (BDNF) and tyrosine kinase B (Trk B) in hippocampus of depressive rats were investigated. Forty-five SD rats were randomly divided into three groups: model control, Vortioxetine and normal control group, with 15 rats in each group. The changes of body mass were recorded within 5 weeks, and the open field test, sugar water preference test and Morris water maze test were performed to evaluate the behavior and mental status of the rats. The expression of BDNF and Trk B in rat hippocampus was detected by enzyme-linked immuno sorbent assay. Compared with the model control group, the body mass, horizontal and vertical movement, sugar and water preference rate of the vortioxetine group in the 5th week were significantly higher than those of the model control group (P<0.05), and significantly lower than those of the normal control group (P<0.05). The escape latency of the Vortioxetine group within 4 days was significantly lower than that of model control group (P<0.05), but higher than that of normal control group (P<0.05). The target quadrant residence time of the Vortioxetine group was significantly lower than that of the model control group (P<0.05), but higher than that of the normal control group (P<0.05). Expression of BDNF and Trk B in the Vortioxetine group was significantly higher than that in the model control group (P<0.05), but lower than that of the normal control group (P<0.05). Collectively, Vortioxetine can effectively alleviate the symptoms of autonomous and exploratory behavior, and reduce the decrease of learning and memory in depressive rats. Vortioxetine can increase the expression of BDNF and Trk B in depressive rats and alleviate their depressive behavior.

Neuroprotective efficacy of different levels of high-frequency repetitive transcranial magnetic stimulation in mice with CUMS-induced depression: Involvement of the p11/BDNF/Homer1a signaling pathway. J Psychiatr Res 2020; 125:152-163. [PMID: 32289652 DOI: 10.1016/j.jpsychires.2020.03.018] [Citation(s) in RCA: 23] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/04/2020] [Revised: 03/03/2020] [Accepted: 03/31/2020] [Indexed: 12/18/2022]
Abstract
High-frequency repetitive transcranial magnetic stimulation (HF-rTMS) is widely used to treat depression. However, the underlying mechanism has not been identified, and there is uncertainty regarding the optimal choice of stimulus parameters, especially stimulus frequency. Our previous study in mice demonstrated that 10-Hz HF-rTMS ameliorated depression by inducing expression of Homer1a and reducing excitability of cortical pyramidal cells. The aims of this study were to compare the effects of 15-Hz and 25-Hz HF-rTMS in a model of chronic unpredictable mild stress (CUMS)-induced depression and investigate its possible molecular mechanism. Male C57BL/6J mice were treated with CUMS for 28 days followed by 15-Hz and 25-Hz rTMS for 4 weeks. The sucrose preference, open field, forced swimming, and tail suspension tests were used to evaluate depression-like behaviors. Immunostaining was performed to measure neuronal loss and neurogenesis. Apoptosis was detected by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling staining. Expression of synapse-related proteins and the effects of HF-rTMS on the signaling pathway were examined using Western blot. The results showed that both 15-Hz and 25-Hz rTMS had significant antidepressant effects; 15-Hz rTMS seemed to be more effective than 25-Hz rTMS in preventing neuronal loss and promoting neurogenesis, while 25-Hz rTMS was superior to 15-Hz rTMS in facilitating synaptic plasticity. We also found that 15-Hz and 25-Hz rTMS markedly increased expression of p11, BDNF, Homer1a, and p-trkB proteins. These findings suggest that 15-Hz and 25-Hz HF-rTMS could exert neuroprotective effects to different degrees via multiple perspectives, which at least in part involve the p11/BDNF/Homer1a pathway.
