        Establishment of a novel myocarditis mouse model based on cyclosporine A

        Zhao Tian Hao,Jiang Yi Xuan,Chen Kai Qin,Qiu Dan,Xu Yan Zhe,Ye Chun,Ren Ting,Zhang Bo,Dai Bin,Hu Jue,Lu Jun,Zhou Fang Liang,Xiao Rong,Lu Fang Guo,Wei Ke 한국유전학회 2022 Genes & Genomics Vol.44 No.12

        Background: Myocarditis is a myocardial injury that can easily cause adolescent death. Traditional research models of animal invasion with viral components, lipopolysaccharide (LPS) or porcine myocardial myosin, among others, have the shortcomings of potential biological safety hazards and high animal mortality. Objective: To explore the construction of a novel myocarditis model with cyclosporine A and the potential genes and pathways associated with it. Methods: BALB/c mice were used in this study, and cyclosporin A and LPS were injected into the peritoneal cavity of mice. The successful establishment of the model was assessed by detecting serum myocardial injury markers and inflammatory factors levels, HE, IHC staining, and RT-qPCR methods. Key genes were obtained using the GSE35182 dataset from the GEO database and validated with the RT-qPCR method. Results: We found that a large number of inflammatory cells infiltrated the myocardium of mice in each group of Cyclosporin A constructed model, while the expression of inflammatory factor indicators was increased, and this model has the characteristics of high degree of local inflammation in myocardial tissue, low mortality, and safe and non-toxic treatment. Using GSE35182 data, we selected 18 Hub genes and validated Hub genes in myocardial tissue with RT-qPCR and found that multiple signaling pathways such as Toll-likereceptor signaling pathway(TLRs), Rap1 signal pathway(Rap1), and Chemokine signaling pathway may be involved in the development of myocarditis. Conclusion: Cyclosporin A can construct a new myocarditis model, and TLRs, Chemokines and Rap1 signaling pathways may be the core pathways of myocarditis.

        Positive Association of TEAD1 With Schizophrenia in a Northeast Chinese Han Population

        Yang Sun,Lin Wen,Yi-Yang Luo,Wen-Juan Hu,Hui-Wen Ren,Ye Lv,Cong Zhang,Ping Gao,Li-Na Xuan,Guan-Yu Wang,Cheng-Jie Li,Zhi-Xin Xiang,Zhi-Lin Luan 대한신경정신의학회 2023 PSYCHIATRY INVESTIGATION Vol.20 No.12

        Objective Schizophrenia is a complex and devastating psychiatric disorder with a strong genetic background. However, much uncertainty still exists about the role of genetic susceptibility in the pathophysiology of schizophrenia. TEA domain transcription factor 1 (TEAD1) is a transcription factor associated with neurodevelopment and has modulating effects on various nervous system diseases. In the current study, we performed a case–control association study in a Northeast Chinese Han population to explore the characteristics of pathogenic <i>TEAD1</i> polymorphisms and potential association with schizophrenia.Methods We recruited a total of 721 schizophrenia patients and 1,195 healthy controls in this study. The 9 single nucleotide polymorphisms (SNPs) in the gene region of <i>TEAD1</i> were selected and genotyped.Results The genetic association analyses showed that five SNPs (rs12289262, rs6485989, rs4415740, rs7113256, and rs1866709) were significantly different between schizophrenia patients and healthy controls in allele or/and genotype frequencies. After Bonferroni correction, the association of three SNPs (rs4415740, rs7113256, and rs1866709) with schizophrenia were still evident. Haplotype analysis revealed that two strong linkage disequilibrium blocks (rs6485989-rs4415740-rs7113256 and rs16911710-rs12364619-rs1866709) were globally associated with schizophrenia. Four haplotypes (C-C-C and T-T-T, rs6485989-rs4415740-rs7113256; G-T-A and G-T-G, rs16911710-rs12364619-rs1866709) were significantly different between schizophrenia patients and healthy controls.Conclusion The current findings indicated that the human <i>TEAD1</i> gene has a genetic association with schizophrenia in the Chinese Han population and may act as a susceptibility gene for schizophrenia.

        Inductorless Broadband Transimpedance Amplifier for 25-Gb/s NRZ and 50-Gb/s PAM-4 Operations in a 90-nm CMOS Technology

        Jau-Ji Jou,Tien-Tsorng Shih,Chih-Chen Peng,Hao-Wen Hsu,Xuan-Yi Ye 대한전자공학회 2021 Journal of semiconductor technology and science Vol.21 No.5

        In this study, an inductorless broadband transimpedance amplifier (TIA) is implemented using TSMC 90-nm complementary metal-oxide-semiconductor (CMOS) technology. A regulated cascode circuit with low input impedance is used as the input stage of the TIA. The core amplifier is a fully differential amplifier with active feedback. The output stage of the TIA is an equalizer based on a differential amplifier with a source degenerated resistor and capacitor. The TIA has a bandwidth of 24.8 GHz and good linearity. In the TIA chip testing, clear 25-Gb/s nonreturn to zero and 50-Gb/s four-level pulse amplitude modulation eye diagrams can be observed.
