Prog Neuropsychopharmacol Biol Psychiatry 2024; 128:110844. [PMID: 37640149 DOI: 10.1016/j.pnpbp.2023.110844] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Revised: 08/07/2023] [Accepted: 08/19/2023] [Indexed: 08/31/2023]
Abstract
Inflammation stimulates the hypothalamic-pituitary adrenal (HPA) axis and triggers glial neuroinflammatory phenotypes, which reduces monoamine neurotransmitters by activating indoleamine 2,3-dioxygenase enzyme. These changes can induce psychiatric diseases, including anxiety. Corticotropin releasing hormone receptor 2 (CRHR2) in the HPA axis is involved in the etiology of anxiety. Omega(n)-3 polyunsaturated fatty acids (PUFAs) can attenuate anxiety through anti-inflammation and HPA axis modulation. However, the underlying molecular mechanism by CRHR2 modulates anxiety and its correlation with neuroinflammation remain unclear. Here, we first constructed a crhr2 zebrafish mutant line, and evaluated anxiety-like behaviors, gene expression associated with the HPA axis, neuroinflammatory response, neurotransmitters, and PUFAs profile in crhr2+/+ and crhr2-/- zebrafish. The crhr2 deficiency decreased cortisol levels and up-regulated crhr1 and down-regulated crhb, crhbp, ucn3l and proopiomelanocortin a (pomc a) in zebrafish. Interestingly, a significant increase in the neuroinflammatory markers, translocator protein (TSPO) and the activation of microglia M1 phenotype (CD11b) were found in crhr2-/- zebrafish. As a consequence, the expression of granulocyte-macrophage colony-stimulating factor, pro-inflammatory cytokines vascular endothelial growth factor, and astrocyte A1 phenotype c3 were up-regulated. While microglia anti-inflammatory phenotype (CD206), central anti-inflammatory cytokine interleukin-4, arginase-1, and transforming growth factor-β were downregulated. In parallel, crhr2-deficient zebrafish showed an upregulation of vdac1 protein, a TSPO ligand, and its downstream caspase-3. Furthermore, 5-HT/5-HIAA ratio was decreased and n-3 PUFAs deficiency was identified in crhr2-/- zebrafish. In conclusion, anxiety-like behavior displayed by crhr2-deficient zebrafish may be caused by the HPA axis dysfunction and enhanced neuroinflammation, which resulted in n-3 PUFAs and monoamine neurotransmitter reductions.

Abstract
Colorectal cancer (CRC) is the third most common cancer and one of the main causes of death around the world. Multiple lines of evidence have suggested the role of the corticotropin-releasing hormone (CRH) family in CRC induction, including the low expression of corticotropin-releasing hormone receptor 2 (CRHR2), which is an angiogenesis inhibitor and inflammatory modulator. Previous research suggests that CRHR2 expression in colonic intestinal cells can regulate migration, proliferation and apoptosis through the modulation of several pathways. The aim of this study was to analyze the association of the rs10250835, rs2267716 and rs2267717 variants of CRHR2 gene with CRC in the Mexican population in order to consider its predictive value in CRC. This cross-sectional study included a group of 187 unrelated patients with sporadic CRC and a control group of 191 healthy blood donors. DNA extraction from peripheral blood was carried out using the Miller method. Identification of the rs10250835 variant was performed using PCR-restriction fragment length polymorphism (RFLP) and the rs2267716 and rs2267717 variants using TaqMan allelic discrimination assay. The minor allele homozygous CC of the rs2267716 variant of CRHR2 showed significant difference between CRC and control group (p=0.025), as well as the GCA haplotype (p=0.007), corresponding to the rs10250835, rs2267716 and rs2267717 variants, respectively. Our results suggest that the rs2267716 variant and GCA haplotype of CRHR2 represent a risk factor for CRC development in Mexican patients.

Abstract
In the early 2000s, emerging SARS‐CoV‐2, which is highly pathogenic, posed a great threat to public health. During COVID‐19, epigenetic regulation is deemed to be an important part of the pathophysiology and illness severity. Using the Illumina Infinium Methylation EPIC BeadChip (850 K), we investigated genome‐wide differences in DNA methylation between healthy subjects and COVID‐19 patients with different disease severities. We conducted a combined analysis and selected 35 “marker” genes that could indicate a SARS‐CoV‐2 infection, including 12 (ATHL1, CHN2, CHST15, CPLX2, CRHR2, DCAKD, GNAI2, HECW1, HYAL1, MIR510, PDE11A, and SMG6) situated in the promoter region. The functions and pathways of differentially methylated genes were enriched in biological processes, signal transduction, and the immune system. In the “Severe versus Mild” group, differentially methylated genes, after eliminating duplicates, were used for PPI analyses. The four hub genes (GNG7, GNAS, PRKCZ, and PRKAG2) that had the highest degree of nodes were identified and among them, GNG7 and GNAS genes expressions were also downregulated in the severe group in sequencing results. Above all, the results suggest that GNG7 and GNAS may play a non‐ignorable role in the progression of COVID‐19. In conclusion, the identified key genes and related pathways in the current study can be used to study the molecular mechanisms of COVID‐19 and may provide possibilities for specific treatments.

Abstract
Background Due to the onset of metastases, the survival rate of lung adenocarcinoma (LUAD) is still low. In view of this, we performed this study to screen metastasis-associated genes and lncRNAs in LUAD. Methods The mRNA and lncRNA expression profiles of 185 metastatic LUAD and 217 non-metastatic LAUD samples were retrieved from the TCGA database and included in this study. The differentially expressed mRNAs (DEmRNAs) and lncRNAs (DElncRNAs) between metastatic samples and non-metastatic samples of LAUD, as well as the cis nearby-targeted DEmRNAs of DElncRNAs and the DElncRNA-DEmRNA co-expression network, were obtained. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the expression levels of selected DEmRNAs. Survival analysis of selected DElncRNAs and DEmRNAs was performed. Results In total, 1351 DEmRNAs and 627 DElncRNAs were screened between the LUAD primary tissue samples and metastatic samples. Then, 194 DElncRNA-nearby-targeted DEmRNA pairs and 191 DElncRNA-DEmRNA co-expression pairs were detected. Except for RHCG and KRT81, the expression of the other six DEmRNAs in the qRT-PCR results generally exhibited the same pattern as that in our integrated analysis. The expression of CRHR2, FAM83A-AS1, FAM83A and Z83843.1 was significantly correlated with the overall survival time of patients with metastatic LUAD. Conclusion We speculate that two interaction pairs (FAM83A-AS1-FAM83A and Z83843.1-MATR3) and four genes (CRHR2, UGT2B15, CHGB and NEFL) are closely associated with the metastasis of LUAD.

Genotyping of immune-related loci associated with delayed HBeAg seroconversion in immune-active chronic hepatitis B patients. Antiviral Res 2020; 176:104719. [PMID: 32004619 DOI: 10.1016/j.antiviral.2020.104719] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2019] [Revised: 12/26/2019] [Accepted: 01/23/2020] [Indexed: 02/07/2023]
Abstract
The progression of chronic hepatitis B (CHB) is associated with single-nucleotide polymorphisms (SNPs). In this study, we demonstrated the association between immune-related SNPs and delayed spontaneous HBeAg seroconversion in immune-active CHB patients. In addition, we investigated the impact of delayed spontaneous HBeAg seroconversion-related SNPs on HBeAg seroconversion within 3 years during antiviral treatment. We enrolled 332 CHB patients and genotyped 124 SNPs associated with HBV-infected clinical outcomes, including 32 interleukin-related genes, 62 HLA genes, 9 CD marker genes, 7 NK cell receptor genes, and 14 other genes, using ABI OpenArray as a platform. Comparing the immune-active CHB patients with delayed spontaneous HBeAg seroconversion (persistent HBeAg seropositivity, older than 40 years) to those with early inefficient HBeAg seroconversion (HBeAg seroconversion with high viremia, younger than 40 years), logistic analysis revealed that rs3820998 (TANK), rs2621377 (HLA-DOB), rs3130215 (HLA-DPB2), rs2255336 (KLRK1), and rs11614913 (MIR-196A2) were significantly associated with delayed spontaneous HBeAg seroconversion. Using multivariate analysis, we determined that high serum HBV DNA levels (OR = 1.66, 95% CI = 1.33-2.08), rs3820998 (CA, OR = 3.37, 95% CI = 1.24-9.12), rs2621377 (TC, OR = 4.96, 95% CI = 1.85-13.3), rs2255336 (TT, OR = 0.09, 95% CI = 0.01-0.86), and rs11614913 (TT, OR = 2.53, 95% CI = 1.05-6.11) were five independent risk factors for delayed spontaneous HBeAg seroconversion. After patients received nucleos(t)ide analogue treatment, rs3820998 heterozygous CA variant conversely became the only independent favorable factor for treatment-induced HBeAg seroconversion within 3 years (OR = 0.21, 95% CI = 0.06-0.78). These results indicate that distinct immune-related SNPs play a vital role in regulating HBeAg status in immune-active CHB patients with or without antiviral treatment.

Abstract
Hepatitis C virus (HCV)-infected patients are at risk of developing hepatocellular carcinoma (HCC). Individuals at heightened risk could be targeted by intensive follow-up surveillance. We have conducted a systematic review of the literature to identify host genetic predisposition to HCC in HCV-infected patients. A comprehensive search of Medline and Embase databases was performed, and the strength of evidence of associations for each gene on development of HCC was evaluated. We identified 166 relevant studies, relating to 137 different genes, or combinations thereof. Seventeen genes were classified as having "good" evidence of an association, a significant association was observed for 37 genes but this finding had not yet been replicated, 56 genes had mixed or limited evidence of an association, and 27 genes showed no association. IFNL3/4, TNF-α and PNPLA3 genes had the most evidence of an association. There was, however, considerable heterogeneity in study design and data quality. In conclusion, we identified a number of genes with evidence of association with HCC, but also a need for more standardized approaches to address this clinically critical question. It is important to consider the underlying mechanism of these relationships and which are confounded by the presence of other HCC risk factors and response to therapy. We also identified many genes where the evidence of association is contradictory or requires replication, as well as a number where associations have been studied but no evidence found. These findings should help to direct future studies on host genetic predisposition to HCC in HCV-infected patients.

Abstract
As more than 80% of hepatocellular carcinoma patients in Japan also suffer from hepatitis C virus infections some time in their medical history, identifying genetic aberrations associated to hepatitis C virulence in these individuals remains a high priority in the diagnosis and treatment of hepatocellular carcinoma. From the BioBank Japan Project, we acquired 480 subjects of hepatocellular carcinoma, chronic hepatitis and liver cirrhosis, and genotyped 131 clinically relevant host single nucleotide polymorphisms to survey the potential association between certain risk alleles and genes to a patient's predisposition to hepatitis C and liver cancer. Among those polymorphisms, we found 12 candidates with statistical significance to support association with hepatitis C virus susceptibility and genetic predisposition to hepatocellular carcinoma. SNPs in genes such as XPC, FANCA, KDR and BRCA2 also suggested likely connections between hepatitis C virus susceptibility and the contraction of liver diseases. Single nucleotide polymorphisms reported here provided suggestions for genes as biomarkers and elucidated insights briefing the linkage of hepatitis C virulence to the alteration of healthy liver genomic landscape as well as liver disease progression.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is a leading cancer-related cause of death worldwide. There are widespread global differences in HCC risk. Although the impact of geographic prevalence of specific causes of chronic liver disease on HCC is recognized, the contribution of the underlying genetic architecture to the risk of HCC remains undefined. Our aim was to characterize evolutionary trends in genetic susceptibility to HCC. METHODS We examined the genetic risk associated with HCC risk alleles identified from genome-wide association studies and correlated these with geographic location and temporal and spatial patterns of human migration. RESULTS A moderate increase in differentiation was noted for rs2596542 (F st = 0.106) and rs17401966 (F st = 0.116), single nucleotide polymorphisms (SNPs) associated with an increased risk of HCC in patients with chronic HCV and HBV, respectively. Both of these SNPs show a recent increase in allelic frequency with the most recent human migrations into East Asia, Oceania and the Americas. In contrast another SNP associated with an increased risk of HCC, rs9275572, showed a lack of differentiation (F st = 0.09) with stable allelic expression across populations. The genetic risk score for HCC, based on the allelic frequency and risk odds ratio of five SNPs associated with increased risk of HCC, was greatest in populations from Africa and decreased with subsequent migration into Europe and Asia. However, a major increase was noted with the most recent migrations into Oceania and the Americas. CONCLUSIONS There are differences in directional differentiation of HCC risk alleles across human populations that can contribute to population-based differences in HCC prevalence.

Abstract
BACKGROUND The discoidin domain receptor tyrosine kinase 1 (DDR1) is positioned within the major histocompatibility complex (MHC) region which plays an important role in the immune system. In addition, DDR1 has been elucidated to be downregulated during the epithelial-mesenchymal transition of bronchial epithelium. OBJECTIVE To investigate the potential genetic associations between DDR1 and aspirin-exacerbated respiratory disease (AERD), this study conducted association studies of DDR1 single nucleotide polymorphisms (SNPs) with AERD and the obstructive symptom of forced expiratory volume in 1 s (FEV(1)) decline after aspirin provocation. METHODS Nine common SNPs were genotyped in 93 AERD patients and 96 aspirin-tolerant asthma (ATA) controls. The genotype distributions of all loci were in Hardy-Weinberg equilibrium (HWE; p > .05). Results. In the results of logistic analyses using age, sex, smoking status, and atopy as covariates, DDR1 rs1264320 in the intronic region showed a potent association signal with FEV(1) decline by aspirin provocation in asthmatics of this study even after corrections for multiple testing (p = .003 and corrected p = .01). However, the variants of DDR1 were not significantly associated with the AERD development (corrected p > .05). On further comparison of FEV(1) decline by aspirin provocation between AERD and ATA, the variant rs1264320 was found to be associated with the FEV(1) decline of ATA rather than AERD. CONCLUSION Despite the need for further functional evaluations and replications, we conclude that DDR1 polymorphisms are not likely to contribute to predispositions of AERD, but may be potentially associated with FEV(1) decline by aspirin provocation in asthmatics.

Abstract
BACKGROUNDS/AIMS Metastatic tumour antigen 1 (MTA1) promotes angiogenesis by stabilizing hypoxia-inducible factor-1α (HIF-1α), which is closely associated with frequent postoperative recurrence and poor survival in patients with HCC. In this study, we determined single nucleotide polymorphisms (SNPs) in angiogenesis-related genes that are associated with MTA1 overexpression in HCC tissues. METHODS A total of 376 patients with HCC who had received curative surgical resection or liver transplantation were enrolled (312/21/43; HBV/HCV/NBNC). MTA1 expression was determined via immunohistochemistry. Thirty-three common SNPs sites (frequency ≥5%) in the angiogenic protein gene that are closely connected to one another were selected, including MTA1, VEGF, HIF-1α, FGF-2, and IGF-II. RESULTS Expression of MTA1 was detected in 120 HCC tissues (31%). An A allele at position IVS4-81G/A of the MTA1 gene (P = 0.016) and the TT genotype at position +12916C of the VEGF gene (P = 0.023) were significantly associated with MTA1 overexpression. However, the TT genotype at position -13021C (P = 0.011) and the haplotypes CT-CT (-11228C; -13021C) of the IGF-II gene (P(cor) = 0.033) were more common in patients with MTA1-negative HCC. Using multivariate analysis, the A allele at IVS4-81G/A in MTA1 gene (P = 0.015) and a T allele (TT+CT genotype) at -13021C in IGF-II (P = 0.002) were independent risk factors in HCC recurrence after curative surgical resection. CONCLUSIONS The genetic polymorphisms IVS4-81G/A in MTA1 and +12916C in VEGF genes were correlated with MTA1 overexpression. The SNPs in MTA1 and IGF-II genes may be important risk factors for the recurrence of HCC.

Abstract
CXCL14 (C-X-C motif chemokine ligand 14) is a conserved member of chemokine family and functions as a chemoattractant for multiplicate immunocytes. CXCL14 expression is constitutive in normal tissues, but absent in wide range of epithelial tumors. Many reports have claimed its important role in tumorigenesis and vascularization. An association between rs2237062 polymorphism and hepatocellular carcinoma (HCC) susceptibility was found in patients with chronic HCV infection in Japanese population. Here we analyzed, by using a polymerase chain reaction-ligation detection reaction (PCR-LDR), the polymorphism in 202 non-HCC patients with HBV infection, 361 HBV-related HCC patients and 407 healthy controls. The aim was to detect the possible association of this single-nucleotide polymorphism (SNP) with HBV-related HCC susceptibility and progression. However, no association was found between rs2237062 polymorphism and susceptibility to HBV infection or HBV-related HCC. Intriguingly, our stratification analysis revealed that HBV-related HCC patients in advanced phase (TNM-II-IV stage) had significantly higher C allele frequency at this polymorphism than patients at early stage (TNM-I stage) (33.5% vs. 25.7%), and its odds ratio reached 1.47 (95% CI 1.06-2.04, P = 0.021). These results suggest that the rs2237062 polymorphism in the CXCL14 gene might influence HBV-related HCC progression in Chinese population.

Abstract
BACKGROUND Chronic hepatitis B virus (HBV) infection is a risk factor of hepatocellular carcinoma (HCC) in China. Epidermal growth factor (EGF) plays an important role in tumorigenesis. The association between EGF +61 G/A polymorphism and the risk of HCC is still controversial and ambiguous. AIM The objective of this study was to investigate the association between EGF +61 G/A polymorphism and the risk of HCC in a Chinese population. METHODS A hospital-based case-control study was designed in a Chinese population. EGF +61 G/A polymorphisms were determined in 120 chronic HBV-infected HCC patients, 120 chronic HBV-infected cirrhotic patients, and 120 healthy controls. The genotype frequency of this polymorphism was determined by using a polymerase chain reaction-restriction fragment length polymorphism assay. RESULTS EGF +61 GG (odds ratio=2.76, 95% confidence interval=1.03, 7.38; p=0.04) and G allele frequencies (odds ratio=1.59, 95% confidence interval=1.08, 2.34; p=0.02) in the HCC group were higher than those in the cirrhosis group. EGF +61 A and G allele frequencies in healthy subjects were 28.8% and 71.2%. No relationship between EGF +61 G/A gene polymorphism and HCC risk was found among our recruited HCC patients and healthy controls. CONCLUSION This study suggests that EGF +61 GG genotype is associated with a higher risk of chronic HBV-infected HCC in the Chinese population.

Abstract
Hepatocellular carcinoma (HCC) is the fifth most common cancer and the third leading cause of cancer death worldwide. Despite recent advances in the diagnosis and treatment of HCC, its prognosis remains dismal. Infection with hepatitis B virus (HBV) and hepatitis C virus (HCV) are the major risk factors for HCC. Although both are hepatotropic viral infections, there are important differences between the oncogenic mechanisms of these two viruses. In addition to the oncogenic potential of its viral proteins, HBV, as a DNA virus, can integrate into host DNA and directly transform hepatocytes. In contrast, HCV, an RNA virus, is unable to integrate into the host genome, and viral protein expression has a more critical function in hepatocarcinogenesis. Both HBV and HCV proteins have been implicated in disrupting cellular signal transduction pathways that lead to unchecked cell growth. Most HCC develops in the cirrhotic liver, but the linkage between cirrhosis and HCC is likely multifactorial. In this review, we summarize current knowledge regarding the pathogenetic mechanisms of viral HCC.
