Association Between the Polymorphism of Steroid Hormone Metabolism Genes and High-Altitude Pulmonary Edema in the Chinese Han Population.

ABSTRACT:

Purpose

Steroid hormone metabolism plays an essential role in high-altitude pulmonary edema (HAPE) progression. This study aimed to investigate the association between polymorphism in seven steroid hormone metabolism genes (STAR, HSD3B1, HSD3B2, CYP17A1, CYP21A2, CYP11B1, and CYP11B2) and HAPE susceptibility among Han Chinese.

Patients and methods

A total of 41 tagSNPs in the seven genes were genotyped using Sequenom MassARRAY SNP assays from 169 HAPE patients (HAPE-p) and 309 matched Han Chinese individuals resistant to HAPE (HAPE-r). The genotypic and allele frequencies, odds ratios (ORs), and 95% confidence intervals (95% CIs) were calculated.

Results

Four SNPs, including the allele C of rs6203 (p = 0.034, OR [95% CI] = 1.344 [1.022-1.767]) in HSD3B1, allele G of rs3740397 (p = 0.044, OR [95% CI] = 1.314 [1.007-1.714]) and allele C of rs10786712 (p = 0.039, OR [95% CI] = 0.751 [0.572-0.986]) in CYP17A1, and allele T of rs6402 (p = 0.006, OR [95% CI] = 0.504 [0.306-0.830]) in CYP11B1, were significantly associated with HAPE. The distribution of the genotypes of these SNPs also significantly differed between the HAPE-p and HAPE-r groups. Moreover, six haplotypes (the linkage disequilibrium block including rs10883783, rs4919686, rs3740397, rs3824755, and rs10786712) of CYP17A1 were also significantly associated with HAPE.

Conclusion

The four SNPs located in HSD3B1 (rs6203), CYP17A1 (rs3740397 and rs10786712), and CYP11B1 (rs6402) and the six haplotypes of CYP17A1 are likely to have an effect on HAPE.

Genome-wide association study of high-altitude pulmonary edema in a Han Chinese population.

Project description:A two-stage genome-wide association study (GWAS) was performed to identify and analyze genes and single nucleotide polymorphisms (SNPs) associated with high-altitude pulmonary edema (HAPE) in a Han Chinese patient population. In the first stage, DNA samples from 68 patients with recurrent HAPE were scanned using Affymetrix SNP Array 6.0 Chips, and allele frequencies were compared to those of 84 HapMap CHB samples to identify candidate SNPs. In the second stage, the 77 identified candidate SNPs were examined in an independent cohort of samples from 199 HAPE patients and 304 controls. Associations between SNPs and HAPE risk were tested using various genetic models. Of the 77 original SNPs, 7 were found to be associated with HAPE susceptibility in the second stage of the study. GO and pathway enrichment analysis of the 7 SNPs revealed 5 adjacent genes involved in various processes, including regulation of nucleoside diphosphate metabolism, thyroid hormone catabolism, and low-density lipoprotein receptor activity. These results suggest the identified SNPs and genes may contribute to the physiopathology of HAPE.

NR3C1 gene polymorphisms are associated with high-altitude pulmonary edema in Han Chinese.

Project description:BACKGROUND:High-altitude pulmonary edema (HAPE) is a life-threatening form of non-cardiogenic edema which occurs in unacclimatized individuals after rapid ascent to high altitude. NR3C1 gene encodes for glucocorticoid receptor (GR) which plays an important role in stress and inflammation. This study aimed to investigate the association of NR3C1 polymorphisms with the susceptibility to HAPE in Han Chinese. METHODS:The 30 SNPs in the NR3C1 gene were genotyped by the Sequenom MassARRAY SNP assay in 133 HAPE patients (HAPE-p) and 135 matched Han Chinese resistant to HAPE (HAPE-r). The genotypic and allele frequencies, odds ratios (ORs), and 95% confidence intervals (95% CIs) were calculated, respectively. RESULTS:The 12 SNPs showed a significant difference between the HAPE-p and HAPE-r groups. In allelic model analysis, we found that the allele "A" of rs17287745, rs17209237, rs17209251, rs6877893, and rs1866388; the allele "C" of rs6191, rs6188, and rs2918417; the allele "T" of rs33388 and rs4634384; and the allele "G" of rs41423247 and rs10052957 were associated with increased the risk of HAPE. In the genetic model analysis, we found that rs17287745, rs6191, rs6188, rs33388, rs2918417, rs6877893, rs1866388, rs41423247, rs4634384, and rs10052957 were relevant to the increased HAPE risk under the dominant model. In addition, the haplotype AACACTCAAGTG of the 12 SNPs was detected to be significantly associated with HAPE risk (OR?=?2.044, 95%CI?=?1.339~3.120, P?=?0.0008), while the haplotype GGAGCACGACCG was associated with the decreased risk of HAPE (OR?=?0.573, 95% CI?=?0.333~0.985, P?=?0.0422). CONCLUSIONS:Our findings provide new evidence for the association between SNPs in NR3C1 and an increased risk of HAPE in the Chinese population. NR3C1 polymorphisms are associated with the susceptibility to HAPE in Han Chinese.

MIR17HG polymorphisms contribute to high-altitude pulmonary edema susceptibility in the Chinese population.

Project description:High-altitude pulmonary edema (HAPE) is a common acute altitude sickness. This study was designed to investigate the effect of MIR17HG polymorphisms on HAPE risk in the Chinese population. The Agena MassARRAY platform was used to genotype six single-nucleotide polymorphisms (SNPs) in the MIR17HG gene in 244 HAPE patients and 243 non-HAPE controls. The odds ratio (OR) and 95% confidence interval were used to evaluate the association between each MIR17HG polymorphisms and the risk of HAPE under a polygenetic model. Statistical analysis was performed using the χ2 test. Multifactor dimensionality reduction (MDR) analysis was used to analyze the impacts of SNP-SNP interactions on the risk of HAPE. According to the allele model, the HAPE risk of people with the rs7318578 A allele of MIR17HG was lower than that of people with the C allele (OR 0.74, p = 0.036).Logistic regression analysis of four models for all selected MIR17HG SNPs showed significant differences in the frequencies of rs7318578 (OR 0.74, p = 0.037) and rs17735387 (OR 1.51, p = 0.036) between cases and controls. The results of the sex stratification analysis showed that among males, rs17735387 in the MIR17HG gene is associated with an increased risk of HAPE. MDR analysis showed that the best combination model was a three-locus model incorporating rs72640334, rs7318578, and rs7336610. This study revealed the correlations between rs7318578 and rs17735387 on the MIR17HG gene and the risk of HAPE in the Chinese population, providing a theoretical basis for the early screening, prevention, and diagnosis of HAPE in high-risk populations.

Association between single nucleotide polymorphisms in ADRB2, GNB3 and GSTP1 genes and high-altitude pulmonary edema (HAPE) in the Chinese Han population.

Project description:High altitude pulmonary edema (HAPE) occurs mainly under conditions such as high altitude, rapid ascent, or hypoxia. Previous studies suggest that ADRB2, GNB3, TH, and GSTP1 polymorphisms are associated with various lung diseases. We evaluated whether those polymorphisms are associated with the risk of HAPE in a Chinese Han population. ADRB2, GNB3, TH and GSTP1 polymorphisms were genotyped using a Sequenom MassARRAY. Logistic regression, adjusted for age and gender, was used to evaluate the association between the genotypes and the risk of HAPE by computing odds ratios (ORs) and 95% confidence intervals (95% CIs). The results revealed that GNB3 rs4963516 allele ''G'' (G vs T: OR = 0.70, 95% CI = 0.55-0.90, p = 0.006) was associated with HAPE risk. The ADRB2 rs1042718 alleles had a 1.29-fold (95%CI = 1.00-1.66; p = 0.045) increased risk of HAPE, and the GSTP1 rs749174 alleles had a 0.71-fold (95%CI = 0.52-0.99; p = 0.042) decreased risk of HAPE. Co-dominant and dominant models of GNB3 rs4963516 decreased the risk of HAPE (p = 0.023 and p = 0.008, respectively). Our results indicate GNB3 and GSTP1 polymorphisms may protect against HAPE progression, while ADRB2 polymorphisms are associated with an increased risk of HAPE.

Sequencing the exons of human glucocorticoid receptor (NR3C1) gene in Han Chinese with high-altitude pulmonary edema.

Project description:High-altitude pulmonary edema (HAPE) is a serious acute mountain sickness that mainly occurs in non-acclimatized individuals after rapid ascent to high altitude. The precise etiology of HAPE remains unclear. This study aimed to investigate whether NR3C1 gene polymorphism is associated with the susceptibility to HAPE.The exons of NR3C1 gene were sequenced by a ABI 3730 DNA analyzer in 133 HAPE patients and matched 135 healthy Han Chinese controls from the Yushu area in Qinghai (the altitude greater than 3500 m).DNA sequencing showed the heterozygous substitutions at codon 588 (rs6194) in exon 6 and 766 (rs6196) in exon 9 of NR3C1 gene. The genotypic distributions and allelic frequencies of NR3C1 SNP rs6194 showed significant differences in two groups (P?<?0.05). The frequencies of the C allele were significantly higher in the HAPE group than in the control group (P?<?0.05) with an odds ratio of 3.009 (95% CI?=?1.250-7.244). There were no differences in genotypic and allelic frequencies in rs6196 polymorphism between the two groups.NR3C1 gene rs6194 polymorphism is correlated with HAPE susceptibility. CC genotype and C allele of rs6194 polymorphism might increase the risk of HAPE in Han Chinese.

Genetic adaptation to extreme hypoxia: study of high-altitude pulmonary edema in a three-generation Han Chinese family.

Project description:Organismal response to hypoxia is essential for critical regulation of erythropoiesis, other physiological functions, and survival. There is evidence of individual variation in response to hypoxia as some but not all of the affected individuals develop polycythemia, and or pulmonary and cerebral edema. A significant population difference in response to hypoxia exist as many highland Tibetan, Ethiopian, and Andean natives developed adaptive mechanisms to extreme hypoxia. A proportion of non-adapted individuals exposed to high altitude develop pulmonary edema (HAPE), pulmonary hypertension, cerebral edema, and extreme polycythemia. The isolation of causative gene(s) responsible for HAPE and other extreme hypoxia complications would provide a rational basis for specific targeted therapy of HAPE, allow its targeted prevention for at-risk populations, and clarify the pathophysiology of other hypoxic maladaptations. The only suggested genetic linkage among unrelated individuals with HAPE has been with endothelial nitric oxide synthase (eNOS) gene. Here we describe a family with multiple members affected with HAPE in three generations. Families with multiple affected members with HAPE have not been described. We first ruled out linkage of HAPE with the eNOS gene. We then performed an analysis of the whole genome using high-density SNP arrays (Affymetrix v5.0) and, assuming a single gene causation of HAPE, ruled out linkage with 34 other candidate genes. Only the HIF2A haplotype was shared by individuals who exhibit the HAPE phenotype, and work on its possible causative role in HAPE is in progress. The small size of our family does not provide sufficient power for a conclusive analysis of linkage. We hope that collaboration with other investigators with access to more HAPE patients will lead to the identification of gene(s) responsible for HAPE and possibly other maladaptive hypoxic complications.

Association between the IL1R2 rs2072472 polymorphism and high-altitude pulmonary edema risk.

Project description:AimHigh-altitude pulmonary edema (HAPE), as a multifactorial disease, is caused by stress failure and involves both environmental and genetic factors. Study shows that IL-1 receptors can selectively decrease the oxygen arterial hypertension and influence the blood coagulation. So we evaluated whether genetic polymorphisms in IL1R1 and 1L1R2 genes are associated with the risk of HAPE in Chinese Han population.MethodsTen susceptible SNPs in the IL1R1 and IL1R2 genes were genotyped among 265 HAPE cases and 303 controls using the Agena MassARRAY platform. The associations of the SNP frequencies with HAPE were analyzed by chi-square (χ2 ) test/Fisher's test. The genetic models were used to evaluate associations.ResultsIn the allele model, we found that rs2072472 was significantly associated with a 0.73-fold decreased risk of HAPE (OR = 0.73, 95% CI = 0.55-0.97, p = 0.033). In the genetic model analysis, the rs2072472 in IL1R2 gene was associated with a 0.32-fold decreased risk of HAPE in the codominant model, 0.67-fold decreased risk of HAPE in the dominant model, 0.36-fold decreasing the risk of HAPE in the recessive model, and 0.66-fold decreased risk of HAPE in the log-additive model, respectively. We found three candidate SNPs (rs11674595, rs4851527, and rs719250) in the IL1R2 gene have shown strong linkage, and none of the haplotypes was significantly associated with risk of HAPE.ConclusionThese findings suggested that IL1R2 polymorphisms may contribute to the protection of HAPE.

Association of a polymorphism in PON-1 gene with steroid-induced osteonecrosis of femoral head in Chinese Han population.

Project description:BACKGROUND: Treatment with steroids covers a wide spectrum of diseases in clinic. However, some users are suffering from serious side effects of steroid administration, while we enjoy the benefit it brings about. Osteonecrosis of the femoral head (ONFH) is a troublesome one among them. Recent studies have demonstrated that lipid metabolism disorder may play a vital role in pathogenesis of ONFH and mutation of the paraoxonase-1 (PON-1) gene may be involved in the occurrence of this disease. However, the relationship between polymorphisms of PON-1 and ONFH has not been thoroughly studied. The aim of this study was to determine whether PON-1 polymorphisms are associated with steroid-induced ONFH through a cohort study among Chinese Han population. METHODS: This trial applied a case-control scheme to compare the clinical data including PON-1 SNP among 94 patients and 106 control subjects to analyze the association between SNP and risk of steroid-induced ONFH. Time of Flight Mass Spectrometer is utilized for genotyping and the result was analyzed in multivariate analysis models. RESULTS: According to polymorphism test of rs662, its SNP was significantly associated with the risk of ONFH in overdominant analysis model [P value: 0.022; odds ratio (OR): 0.39]. However, genotype frequencies of rs662 of PON-1 gene between case and control group showed no differences (P?>?0.05). CONCLUSIONS: Our data suggest for the first time that SNP (rs662) of the PON-1 gene was associated with the risk of steroid-induced ONFH. In addition, PAI-1 SNPs may play an important role in pathogenesis of ONFH.

Effect of PRDX6 gene polymorphism on susceptibility to chronic obstructive pulmonary disease in the Chinese Han population.

Project description:BackgroundTo explore the relationship of peroxiredoxin6 (PRDX6) tag-single nucleotide polymorphisms (SNPs) with susceptibility to chronic obstructive pulmonary disease (COPD) in the Chinese Han population.MethodsA total of 502 patients with COPD and 481 healthy controls from nine hospitals in China were enrolled in this study. The PRDX6 tag-SNPs were identified by linkage disequilibrium (LD) analysis in 30 healthy controls. The associations between identified tag-SNPs and COPD risk were further evaluated.ResultsFour PRDX6 tag-SNPs, including rs7314, rs34619706, rs33951697, and rs4382766, were identified in 30 healthy controls. Moreover, in the allele model, there was no statistical difference in locus in PRDX6 between patients with COPD and healthy controls (P > 0.05). However, in the recessive model, rs33951697 locus in PRDX6 gene carrier with T/T had an increased risk of COPD (odds ratio [OR] = 2.59, 95% CI = 1.06-6.33, P = 0.028). Furthermore, in the relevance analysis between genetic polymorphisms and smoking behavior and lung function indexes, we found that the number of smoked cigarettes per day and FEV1/FVC differed among different genotypes of PRDX6, rs4382766, and rs7314 (P < 0.05).ConclusionPRDX6 gene polymorphism with smoking status may contribute to the etiology of COPD in the Chinese Han population.

Whole transcriptomic landscape and regulatory network of High-Altitude Pulmonary Edema

Project description:High Altitude Pulmonary Edema (HAPE) is a type of idiopathic non-cardiogenic pulmonary oedema at high altitude with a severe clinical course and high mortality rate. Therefore, this study aims to investigate transcriptomic signatures in HAPE based on whole-transcriptome sequencing. We identified the differential expression of mRNAs, miRNAs, circRNAs, lncRNAs, alternative splicing (AS) events, gene fusions and novel transcripts, constructed ceRNA networks and immune cell infiltration landscapes, and annotated the biological functions of target genes based on bioinformatics analysis. This study will clarify the differential expression of coding and non-coding RNAs (ncRNAs) in HAPE, identify novel transcripts and genes, increase our understanding of the transcriptional characteristics of HAPE, elucidate disease-associated pathways and biological processes, and provide underlying mechanisms for HAPE diagnosis and treatment.
