Abstract
Spontaneous intracerebral hemorrhage (ICH) is a common fatal event without an effective therapy. Of note, some familial aggregation and inherited tendency is found in ICH and heritability estimates indicate that genetic variations contribute substantially to ICH risk and outcome. Thus, identification of genetic variants that affect the occurrence and outcome may be helpful for ICH prevention and therapy. There are several reviews summarizing numerous genetic variants associated with the occurrence of ICH before, but genetic variants contributing to location distribution and outcome have rarely been introduced. Here, we summarize the current knowledge of genetic variants and pay special attention to location distribution and outcome. So far, investigations have reveled variations in APOE, GPX1, CR1, ITGAV, PRKCH, and 12q21.1 are associated with lobar ICH (LICH), while ACE, COL4A2, 1q22, TIMP1, TIMP2, MMP2, MMP9, and TNF are associated with deep ICH (DICH). Moreover, variations in APOE, VWF, 17p12, HP, CFH, IL6ST, and COL4A1 are possible genetic contributors to ICH outcome. Furthermore, the prospects for ICH related genetic studies from the bench to the bed were discussed.

J Med Biochem 2021; 40:138-149. [PMID: 33776563 PMCID: PMC7982289 DOI: 10.5937/jomb0-26839] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2020] [Accepted: 08/26/2020] [Indexed: 11/05/2022] Open
Abstract
BACKGROUND In the final phase of clot formation, fibrinogen constitutes frame, whereas factor XIII (FXIII) active form is responsible for the covalent cross-linking of fibrin fibres and plasmin inhibitor (PI), thus contributing to clot stability. It could be expected that any change of coagulation factors' structure affects the clot formation and modulates the atherothrombotic risk. The aim was to determine the frequency of four single nucleotide polymorphisms: (i) A > G in codon 312 of the fibrinogen α-chain gene (rs6050, Thr312AlaFGA), (ii) C > T at position 10034 of the 3 - untranslated region in the fibrinogen γ-chain gene (rs2066865, 10034C > T FGG), (iii) C > T in codon 564 of the FXIII-A subunit gene (rs5982, Pro564LeuFXIII-A), and (iv) C > T in codon 6 of the plasmin inhibitor gene (rs2070863, Arg6TrpPI) in Croatian patients and their association with coronary artery disease (CAD). METHODS We performed the unrelated case-control association study on the consecutive sample of patients 18 years old, who had undergone coronary angiography for investigation of chest pain and suspected CAD. The cases were patients with confirmed CAD (N=201), and the controls were the subjects with no CAD (N=119). Samples were genotyped using PCR-RFLP analysis. RESULTS Observed frequencies of the rare alleles of Thr312Ala FGA, 10034C > T FGG, Leu564Pro FXIII-A and Arg6Trp PI polymorphisms were 21%, 17%, 14%, 20%, respectively. Patients with 10034C > T FGG CC genotype had 3.5 times (95% CI 1.02-12.03) higher adjusted odds for CAD than patients with 10034C > T FGG TT genotype. Patients with Arg6Trp PI CC genotype had 3.86 times (95% CI 1.23-12.12) higher odds for CAD than patients with Arg6Trp PI TT genotype. It seems that those genotype-related higher odds are also male-gender related. No difference was observed regarding any other investigated polymorphism. CONCLUSIONS Our finding suggests that 10034C > T FGG and Arg6Trp PI are associated with CAD.

Abstract
Objective Intracerebral hemorrhage (ICH) is a subtype of stroke with high mortality and morbidity rates. Our aim was to comprehensively analyze transcriptome and proteome in an experimental ICH model. Methods All mice were divided into ICH model (n = 3) and sham groups (n = 3). ICH was induced by collagenase VII. The ipsilateral hemisphere was used for whole transcriptome and proteomics resequencing. After preprocessing, differentially expressed lncRNAs (DElncRNAs), mRNAs (DEmRNAs), miRNAs (DEmiRNAs), and DEproteins between ICH and sham groups were identified. Functional enrichment analysis was performed using the clusterProfiler package, followed by protein–protein interaction (PPI) analysis. After that, the Pearson correlation coefficient between DEmRNAs and DElncRNAs or between DEmRNAs and DEproteins was calculated. DElncRNAs with similar functions were analyzed by the GOSemSim package. After prediction of DEmiRNA–DEmRNA and DElncRNA–DEmiRNA relationships, a competing endogenous RNA (ceRNA) network was constructed. Several DEmRNAs and DElncRNAs were validated in ipsilateral hemisphere tissues of the ICH model and control groups using RT-qPCR and western blot. Results Between the ICH and sham groups, 31 DElncRNAs, 367 DEmRNAs, 35 DEmiRNAs, and 96 DEproteins were identified. DEmRNAs were mainly enriched in inflammation, such as cytokine–cytokine receptor interaction, IL-17, and TNF signaling pathways. A PPI network of DEmRNAs was constructed and hub genes were identified, such as IL6 (degree = 59), TNF (degree = 44), and CXCR2 (degree = 39). 24 DElncRNAs with similar functions were identified, including 15 up- and 9 down-regulated lncRNAs. After integration of DEmiRNA–DEmRNA and DElncRNA–DEmiRNA relationships, we constructed a ceRNA network, composed of 71 DEmRNAs, 17 DEmiRNAs, and 12 DElncRNAs. RT-qPCR and western blot results confirmed that C3, Fga, and Slc4a1 proteins were more lowly expressed and Penk was more highly expressed in ICH than control groups, which could become potential markers for ICH. Conclusion Our findings identified ICH-related DE-RNAs and proteins and potential molecular mechanisms of ICH by transcriptome resequencing and quantitative proteomic analyses.

Genetic risk of Spontaneous intracerebral hemorrhage: Systematic review and future directions. J Neurol Sci 2019; 407:116526. [PMID: 31669726 DOI: 10.1016/j.jns.2019.116526] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2019] [Revised: 09/18/2019] [Accepted: 10/07/2019] [Indexed: 12/22/2022]
Abstract
BACKGROUND Although highly heritable, few genes have been linked to spontaneous intracerebral hemorrhage (SICH), which does not currently have any evidence-based disease-modifying therapy. Individuals of African ancestry are especially susceptible to SICH, even more so for indigenous Africans. We systematically reviewed the genetic variants associated with SICH and examined opportunities for rapidly advancing SICH genomic research for precision medicine. METHOD We searched the National Human Genome Research Institute-European Bioinformatics Institute (NHGRI-EBI) Genome Wide Association Study (GWAS) catalog and PubMed for original research articles on genetic variants associated with SICH as of 15 June 2019 using the PRISMA guideline. RESULTS Eight hundred and sixty-four articles were identified using pre-specified search criteria, of which 64 met the study inclusion criteria. Among eligible articles, only 9 utilized GWAS approach while the rest were candidate gene studies. Thirty-eight genetic loci were found to be variously associated with the risk of SICH, hematoma volume, functional outcome and mortality, out of which 8 were from GWAS including APOE, CR1, KCNK17, 1q22, CETP, STYK1, COL4A2 and 17p12. None of the studies included indigenous Africans. CONCLUSION Given this limited information on the genetic contributors to SICH, more genomic studies are needed to provide additional insights into the pathophysiology of SICH, and develop targeted preventive and therapeutic strategies. This call for additional investigation of the pathogenesis of SICH is likely to yield more discoveries in the unexplored indigenous African populations which also have a greater predilection.

Abstract
BACKROUND A relatively small number of genetic variants are implicated to pathophysiology of intracerebral hemorrhage (ICH). Aquaporin-4 (AQP4) has been reported to be implicated in the pathophysiological processes of ICH development. OBJECTIVE To examine the role of AQP4 gene region polymorphisms on the ICH risk. METHODS A total of 250 Greek and 193 Polish patients with primary ICH and 250 and 322 respective controls were enrolled, forming two independent cohorts in order to validate any significant effect. With logistic regression analyses, 7 AQP4 tag single nucleotide polymorphisms (SNPs) were examined for association with ICH risk, lobar/non-lobar ICH risk, and 6-month disability after ICH. Cox regression analysis was applied in order to the effect of AQP4 SNPs on ICH age of onset be tested. Correction for multiple comparisons was applied. RESULTS Multivariate logistic regression analysis showed that rs3875089 in the Greek cohort and rs3763043, rs335931 in the Polish cohort had a significant influence on the risk of ICH, lobar and non-lobar ICH. Regarding the age of onset, rs3875089 in the Greek cohort and rs3763043, rs11661256 in the Polish cohort were found to significantly alter the age of onset of ICH and its subtypes. However, all of the above associations did not survive the Bonferroni correction (p-value >0.007). Finally, AQP4 tag SNPs were not found to have any significant effect on long-term disability after ICH. CONCLUSIONS In conclusion, the present study provides an indication that AQP4 gene variants may affect susceptibility to primary ICH and may influence the ICH age of onset.

Abstract
Differences in the incidence of spontaneous intracerebral hemorrhage (ICH) between ethnicities exist, with an estimated 42% of the variance explained by ethnicity itself. Caucasians have a higher proportion of lobar ICH (LICH, 15.4% of all ICH) than do Asians (3.4%). Alterations in the causal factor exposure between countries justify part of the ethnic variance in ICH incidence. One third of ICH risk can be explained by genetic variation; therefore, genetic differences between populations can partly explain the difference in ICH incidence. In this paper, we review the current knowledge of genetic variants associated with ICH in multiple ethnicities. Candidate gene variants reportedly associated with ICH were involved in the potential pathways of hypertension, vessel wall integrity, lipid metabolism, endothelial dysfunction, inflammation, platelet function, and coagulopathy. Furthermore, variations in APOE (in multiple ethnicities), PMF1/SLC25A44 (in European), ACE (in Asian), MTHFR (in multiple ethnicities), TRHDE (in European), and COL4A2 (in European) were the most convincingly associated with ICH. The majority of the associated genes provide small contributions to ICH risk, with few of them being replicated in multiple ethnicities.

Abstract
Α limited number of genetic variants have been linked to the development of intracerebral hemorrhage (ICH). Ιntegrin AV and/or B8-deficient mice were found to develop ICH. The present candidate gene association study was designed to investigate possible influence of integrin AV (ITGAV) and integrin B8 (ITGB8) gene region polymorphisms on the risk of ICH. 1015 participants (250 Greek and 193 Polish patients with primary ICH and 250 Greek and 322 Polish controls) were included in the study. Using logistic regression analyses, 11 tag single nucleotide polymorphisms (SNPs) for ITGAV and 11 for ITGB8 gene were tested for associations with ICH risk, lobar ICH risk and non-lobar ICH after adjustment for age, gender, history of hypertension and country of origin. Linear regression models were used to test the effect of tag SNPs on the ICH age of onset. Correction for multiple comparisons was carried out. The rs7565633 tag SNP of the ITGAV gene was independently associated with the risk of lobar ICH in the codominant model of inheritance [odds ratio (95 % confidence interval (CI)) 0.56 (0.36-0.86), p = 0.0013]. Furthermore, heterozygous individuals of the rs10251386 and the rs10239099 of the ITGB8 gene had significantly lower age of ICH onset compared to the wild-type genotypes [regression coefficient (b) -3.884 (95 % CI -6.519, -1.249), p = 0.0039 and b = -4.502 (95 % CI -7.159, -1.845), p = 0.0009, respectively]. The present study provides preliminary indication for an influence of ITGAV gene tag SNP in the development of lobar ICH and of ITGB8 gene variants in the age of ICH onset.

Abstract
Intracerebral haemorrhage (ICH) is associated with the greatest morbidity and mortality of all stroke subtypes. Established risk factors for ICH include hypertension, alcohol use, current cigarette smoking, and use of oral anticoagulants and/or antiplatelet agents. Familial aggregation of ICH has been observed, and the heritability of ICH risk has been estimated at 44%. Few genes have been found to be associated with ICH at the population level, and much of the evidence for genetic risk factors for ICH comes from single studies conducted in relatively small and homogenous populations. In this Review, we summarize the current knowledge of genetic variants associated with primary spontaneous ICH. Two variants of the gene encoding apolipoprotein E (APOE) - which also contributes to the pathogenesis of cerebral amyloid angiopathy - are the most likely candidates for variants that increase the risk of ICH. Other promising candidates for risk alleles in ICH include variants of the genes ACE, PMF1/SLC25A44, COL4A2, and MTHFR. Other genetic variants, related to haemostasis, lipid metabolism, inflammation, and the CNS microenvironment, have been linked to ICH in single candidate gene studies. Although evidence for genetic contributions to the risk of ICH exists, we do not yet fully understand how and to what extent this information can be utilized to prevent and treat ICH.

Abstract
We analyzed a cohort of 36 females with pregnancy loss. In addition to 11 patients with antiphospholipid antibody syndrome and 2 patients with congenital antithrombin (AT) or protein C deficiency, we identified 5 patients with low fibrinogen levels (median 110 mg/dL) prior to 10 weeks of gestation. Four of these 5 patients underwent a fibrinogen gene analysis, and all 4 were found to be heterozygotes for the α-fibrinogen (FGA) Thr321Ala polymorphism. One female without hypofibrinogenemia with a history of 8 pregnancy losses was found to be homozygous for the same polymorphism, and she also showed hypercoagulability without thrombosis. In conclusion, there was a relatively high frequency of pregnancy loss in the setting of hypofibrinogenemia and/or the FGA Thr312Ala polymorphism, and this may be an important risk factor for pregnancy loss and a hypercoagulable state in later pregnancy.
