Genetic history of esophageal cancer group in southwestern China revealed by Y-chromosome STRs and genomic evolutionary connection analysis. Heliyon 2024; 10:e29867. [PMID: 38720733 PMCID: PMC11076658 DOI: 10.1016/j.heliyon.2024.e29867] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2023] [Revised: 04/09/2024] [Accepted: 04/16/2024] [Indexed: 05/12/2024] Open
Abstract
Genetic and environmental factors play crucial roles in the development of esophageal cancer (EC) and contribute uniquely or cooperatively to human cancer susceptibility. Sichuan is located in the interior of southwestern China, and the northern part of Sichuan is one of the regions with a high occurrence of EC. However, the factors influencing the high incidence rate of EC in the Sichuan Han Chinese population and its corresponding genetic background and origins are still poorly understood. Here, we utilized genome-wide single nucleotide polymorphisms (SNPs) and Y-chromosome short tandem repeats (Y-STRs) to characterize the genetic structure, connection, and origin of cancer groups and general populations. We generated Y-STR-based haplotype data from 214 Sichuan individuals, including the Han Chinese EC population and a control group of Han Chinese individuals. Our results, obtained from Y-STR-based population statistical methods (analysis of molecular variance (AMOVA), principal component analysis (PCA), and phylogenetic analysis), demonstrated that there was a genetic substructure difference between the EC population in the high-incidence area of northern Sichuan Province and the control population. Additionally, there was a strong genetic relationship between the EC population in the northern Sichuan high-incidence area and those at high risk in both the Fujian and Chaoshan areas. In addition, we obtained high-density SNP data from saliva samples of 60 healthy Han Chinese individuals from three high-prevalence areas of EC in China: Sichuan Nanchong, Fujian Quanzhou, and Henan Xinxiang. As inferred from the allele frequency of SNPs and sharing patterns of haplotype segments, the evolutionary history and admixture events suggested that the Han population from Nanchong in northern Sichuan Province shared a close genetic relationship with the Han populations from Xinxiang in Henan Province and Quanzhou in Fujian Province, both of which are regions with a high prevalence of EC. Our study illuminated the genetic profile and connection of the Northern Sichuan Han population and enriched the genomic resources and features of the Han Chinese populations in China, especially for the Y-STR genetic data of the Han Chinese EC population. Populations living in different regions with high incidences of EC may share similar genetic backgrounds, which offers new insights for further exploring the genetic mechanisms underlying EC.

[PMID: 31803756 PMCID: PMC6873657 DOI: 10.3389/fmolb.2019.00128] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2019] [Accepted: 10/29/2019] [Indexed: 12/17/2022] Open
Abstract
Mitochondria are the main producers of energy in eukaryotic cells. Mitochondrial dysfunction is associated with specific mitochondrial DNA (mtDNA) variations (haplogroups), and these variations can contribute to human disease. East Asian populations show enrichment of many mitochondrial haplogroups, including A, B, D, G, M7, M8, M9, N9, R9, and exhibit half of the known haplogroups of worldwide. In this review, we summarize the current research in the field of mtDNA variation and associated disease in East Asian populations and discuss the physiological and pathological relevance of mitochondrial biology. mtDNA haplogroups are associated with various metabolic disorders ascribed to altered oxidative phosphorylation. The same mitochondrial haplogroup can show either a negative or positive association with different diseases. Mitochondrial dynamics, mitophagy, and mitochondrial oxidative stress, ultimately influence susceptibility to various diseases. In addition, mitochondrial retrograde signaling pathways may have profound effects on nuclear-mitochondrial interactions, affecting cellular morphology, and function. Other complex networks including proteostasis, mitochondrial unfolded protein response and reactive oxygen species signaling may also play pivotal roles in metabolic performance.

BRCA2 loss-of-function germline mutations are associated with esophageal squamous cell carcinoma risk in Chinese. Int J Cancer 2019; 146:1042-1051. [PMID: 31396961 DOI: 10.1002/ijc.32619] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2019] [Revised: 07/05/2019] [Accepted: 07/24/2019] [Indexed: 12/23/2022]
Abstract
Esophageal squamous cell carcinoma (ESCC) occurs with highest frequency in China with over 90% mortality, highlighting the need for early detection and improved treatment strategies. We aimed to identify ESCC cancer predisposition gene(s). Our study included 4,517 individuals. The discovery phase using whole-exome sequencing (WES) included 186 familial ESCC patients from high-risk China. Targeted gene sequencing validation of 598 genes included 3,289 Henan and 1,228 moderate-risk Hong Kong Chinese. A WES approach identified BRCA2 loss-of-function (LOF) mutations in 3.23% (6/186) familial ESCC patients compared to 0.21% (9/4300) in the ExAC East Asians (odds ratio [OR] = 15.89, p = 2.48 × 10-10 ). BRCA2 LOF mutation frequency in the combined Henan cohort has significantly higher prevalence (OR = 10.55, p = 0.0035). Results were independently validated in an ESCC Hong Kong cohort (OR = 10.64, p = 0.022). One Hong Kong pedigree was identified to carry a BRCA2 LOF mutation. BRCA2 inactivation in ESCC was via germline LOF mutations and wild-type somatic allelic loss via loss of heterozygosity. Gene-based association analysis, including LOF mutations and rare deleterious missense variants defined with combined annotation dependent depletion score ≥30, confirmed the genetic predisposition role of BRCA2 (OR = 9.50, p = 3.44 × 10-5 ), and provided new evidence for potential association of ESCC risk with DNA repair genes (POLQ and MSH2), inflammation (TTC39B) and angiogenesis (KDR). Our findings are the first to provide compelling evidence of the role of BRCA2 in ESCC genetic susceptibility in Chinese, suggesting defective homologous recombination is an underlying cause in ESCC pathogenesis, which is amenable to therapeutic options based on synthetic lethality approaches such as targeting BRCA2 with PARP1 inhibitors in ESCC.

Abstract
Mitochondria are essential intracellular organelles that are responsible for energy metabolism, cell growth, and differentiation, redox homeostasis, oncogenic signaling, and apoptosis. These multifunctional organelles have been implicated in cancer initiation, progression, and metastasis, relapse, and acquired drug resistance due to metabolic alterations in transformed cells. Maternally inherited mitochondrial DNA (mtDNA) is thought to contribute to cancer development and prognosis and proposed as a therapeutic target for cancer treatment. In this review, we summarize the current knowledge of mtDNA alterations, with a specific focus on somatic changes, germline variants, haplogroups, large deletions, and mtDNA content changes associated with cancer susceptibility and prognosis. We also discuss the potential of mtDNA as biomarkers of cancer detection and targets of cancer treatment. Deeper understanding of the mechanisms underlying these associations requires further investigation.

Ancestry and different rates of suicide and homicide in European countries: A study with population-level data. J Affect Disord 2018; 232:152-162. [PMID: 29494899 DOI: 10.1016/j.jad.2018.02.030] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/28/2017] [Revised: 01/02/2018] [Accepted: 02/16/2018] [Indexed: 01/28/2023]
Abstract
INTRODUCTION There are large differences in suicide rates across Europe. The current study investigated the relationship of suicide and homicide rates in different countries of Europe with ancestry as it is defined with the haplotype frequencies of Y-DNA and mtDNA. MATERIAL AND METHODS The mortality data were retrieved from the WHO online database. The genetic data were retrieved from http://www.eupedia.com. The statistical analysis included Forward Stepwise Multiple Linear Regression analysis and Pearson Correlation Coefficient (R). RESULTS In males, N and R1a Y-DNA haplotypes were positively related to both homicidal and suicidal behaviors while I1 was negatively related. The Q was positively related to the homicidal rate. Overall, 60-75% of the observed variance was explained. L, J and X mtDNA haplogroups were negatively related with suicide in females alone, with 82-85% of the observed variance described. DISCUSSION The current study should not be considered as a study of genetic markers but rather a study of human ancestry. Its results could mean that research on suicidality has a strong biological but locally restricted component and could be limited by the study population; generalizability of the results at an international level might not be possible. Further research with patient-level data are needed to verify whether these haplotypes could serve as biological markers to identify persons at risk to commit suicide or homicide and whether biologically-determined ancestry could serve as an intermediate grouping method or even as an endophenotype in suicide research.

Abstract
Mitochondria, which are multi-functional, have been implicated in cancer initiation, progression, and metastasis due to metabolic alterations in transformed cells. Mitochondria are involved in the generation of energy, cell growth and differentiation, cellular signaling, cell cycle control, and cell death. To date, the mitochondrial basis of cancer disparities is unknown. The goal of this review is to provide an understanding and a framework of mitochondrial determinants that may contribute to cancer disparities in racially different populations. Due to maternal inheritance and ethnic-based diversity, the mitochondrial genome (mtDNA) contributes to inherited racial disparities. In people of African ancestry, several germline, population-specific haplotype variants in mtDNA as well as depletion of mtDNA have been linked to cancer predisposition and cancer disparities. Indeed, depletion of mtDNA and mutations in mtDNA or nuclear genome (nDNA)-encoded mitochondrial proteins lead to mitochondrial dysfunction and promote resistance to apoptosis, the epithelial-to-mesenchymal transition, and metastatic disease, all of which can contribute to cancer disparity and tumor aggressiveness related to racial disparities. Ethnic differences at the level of expression or genetic variations in nDNA encoding the mitochondrial proteome, including mitochondria-localized mtDNA replication and repair proteins, miRNA, transcription factors, kinases and phosphatases, and tumor suppressors and oncogenes may underlie susceptibility to high-risk and aggressive cancers found in African population and other ethnicities. The mitochondrial retrograde signaling that alters the expression profile of nuclear genes in response to dysfunctional mitochondria is a mechanism for tumorigenesis. In ethnic populations, differences in mitochondrial function may alter the cross talk between mitochondria and the nucleus at epigenetic and genetic levels, which can also contribute to cancer health disparities. Targeting mitochondrial determinants and mitochondrial retrograde signaling could provide a promising strategy for the development of selective anticancer therapy for dealing with cancer disparities. Further, agents that restore mitochondrial function to optimal levels should permit sensitivity to anticancer agents for the treatment of aggressive tumors that occur in racially diverse populations and hence help in reducing racial disparities.

Abstract
Esophageal cancer is the sixth leading cause of cancer-associated death worldwide. Phospholipase C epsilon 1 (PLCE1) gene was found to be associated with the risk of esophageal squamous cell carcinoma (ESCC) by three large-scale genome-wide association studies (GWAS) in Chinese populations. To evaluate the association between the single nucleotide polymorphisms (SNPs) in PLCE1 gene and ESCC risk, a case-control study including 550 patients with ESCC and 550 age, gender-matched controls was carried out to investigate the genetic susceptibility of three SNPs (rs3765524 C/T and two unreported potentially functional SNPs rs10882379 G/A and rs829232 G/A) as well as the interactions of gene-gene and gene-environment in the development of ESCC. And the results showed that GA genotype of rs10882379 was significantly associated with reduced ESCC risk compared with GG genotype (adjusted OR [95% CI]: 0.66 [0.51, 0.86]), while AA genotype of rs829232 was significantly associated with increased ESCC risk compared with GG genotype (adjusted OR [95% CI]: 1.37 [1.12, 1.67]). The haplotype analysis showed increased ESCC risk in Grs10882379Crs3765524Ars829232 and Grs10882379Trs3765524Ars829232 haplotypes with OR (95% CI) of 1.40 (1.13, 1.73) and 1.66 (1.18, 2.34), respectively and inversely reduced ESCC risk in Ars10882379Crs3765524Grs829232 haplotype with OR (95% CI) of 0.74 (0.61, 0.91). The gene-environment interaction analysis emerged a best model consisted of four factors (rs10882379, rs3765524, rs829232 and family history of ESCC) that could increase the ESCC risk in the 'high risk group' with 4.45-fold (OR [95% CI]: 5.45 [4.13, 7.19]), compared to the 'low risk group.' Our results further validate that the SNPs in PLCE1 gene may contribute to the ESCC susceptibility in Chinese Han population. Also the gene-gene and gene-environment interactions play a certain crucial role in the ESCC progression.

Abstract
Background Recurrent genetic abnormalities that correlate with clinical features could be used to determine patients' prognosis, select treatments and predict responses to therapy. Esophageal squamous cell carcinoma (ESCC) contains genomic alterations of undefined clinical significance. We aimed to identify mutually exclusive mutations that are frequently detected in ESCCs and characterized their associations with clinical variables. Methods We analyzed next-generation-sequencing data from 104 ESCCs from Taihang Mountain region of China; 96 pairs were selected for deep target-capture-based validation and analysis of clinical and pathology data. We used model proposed by Szczurek to identify exclusive mutations and to associate these with pathology findings. Univariate and multivariate analyses with Cox proportional hazards model were used to examine the association between mutations and overall survival and response to chemotherapy. Findings were validated in an analysis of samples from 89 patients with ESCC from Taihang Mountain. Results We identified statistically significant mutual exclusivity between mutations in NOTCH1 and PIK3CA in ESCC samples. Mutations in NOTCH1 were associated with well-differentiated, early-stage malignancy and less metastasis to regional lymph nodes. Nonetheless, patients with NOTCH1 mutations had shorter survival times than patients without NOTCH1 mutations, and failed to respond to chemotherapy. In contrast, patients with mutations in PIK3CA had better responses to chemotherapy and longer survival times than patients without PIK3CA mutations. Conclusions In a genetic analysis of ESCCs from patients in China, we identified mutually exclusive mutations in NOTCH1 and PIK3CA. These findings might increase our understanding of ESCC development and be used as prognostic factors.

Abstract
Studies on associations of various polymorphism in xenobiotic metabolizing genes with different cancers including esophageal squamous cell carcinoma (ESCC) are mixed and inconclusive. To evaluate the association of CYP1A1*4, SULT1A1*2 and SULT1A2*2 genotypes with ESCC risk and their modifying effects on different risk factors of ESCC, we conducted a case-control study in Kashmir, India, an area with relative high incidence of ESCC. We recruited 404 histopathologically confirmed ESCC cases, and equal number of controls, individually matched for sex, age and district of residence to respective case. Information was obtained on various dietary, lifestyle and environmental factors in face-to-face interviews, using a structured questionnaire, from each subject. Genotypes were analyzed by polymerase chain reaction, restriction fragment length polymorphism and direct sequencing. Conditional logistic regression models were used to calculate odds ratios (ORs) and 95% confidence intervals (95% CIs). A higher risk was observed in the subjects who harbored variant genotype of CYP1A1*4 (OR = 2.06; 95% CI: 1.28-3.32); and the risk was further enhanced in ever smokers (OR = 3.47; 95% CI: 1.62-7.42), adobe dwellers (OR = 6.71; 95% CI: 3.02-14.89), and biomass fuel users (OR = 5.11; 95% CI: 1.34-19.50). We did not find any significant differences in the polymorphic variants of SULT1A1*2 and SULT1A2*2 between cases and controls. The study indicates that, unlike SULT1A1*2 and SULT1A2*2, the polymorphism of CYP1A1*4 is associated with ESCC risk. However, replicative studies with larger sample size are needed to substantiate our findings.

Abstract
Polymorphisms in glutathione-S-transferases (GSTs), the phase II xenobiotic detoxifying enzymes, have been associated with increased cancer risk. In this study, we assessed the association of functional polymorphisms in GSTM1 and GSTT1 with esophageal cancer in Kashmir, India, an area with a high incidence of esophageal squamous cell carcinoma (ESCC). We analyzed genotypes of GSTM1 and GSTT1 using a multiplex PCR in 492 pairs of ESCC cases and individually matched controls. The associations between polymorphisms in these genes and ESCC risk were examined by conditional logistic regression models adjusted for multiple potential confounders. In addition, the interaction between these genes and several environmental exposures with regard to ESCC risk was assessed. Our results showed an association between the GSTT1 null genotype and ESCC risk (odds ratio (OR) = 1.58; 95% confidence interval (CI) 1.04-2.39). Although GSTM1 alone was not associated with ESCC risk, individuals with the GSTM1 (-)/GSTT1 (+) genotype showed an inverse relation with ESCC risk (OR = 0.55; 95% CI 0.32-0.93), compared to GSTM1 (+)/GSTT1 (+) individuals. We found a significant interaction between the GSTT1 and GSTM1 genotypes with regard to ESCC risk (P = 0.001); however, there were no interactions between environmental factors and GSTT1 and GSTM1 genotypes. This study indicates that GSTT1 null genotype is associated with ESCC risk in Kashmiri population. The association between GSTM1 and ESCC risk needs further investigations. Interactions of these genotypes with environmental exposures should be examined in multicentric studies with bigger sample sizes.

Abstract
We sought to reassess the association of PLCE1 rs2274223 and susceptibility to esophageal cancer (EC) through a meta-analysis of published case-control studies. Using the PubMed and Embase, we identified nine articles including fourteen case-control studies (15,225 cases and 23,620 controls). ORs and 95 % confidence intervals (CIs) of GG vs. AA, GG + GA vs. AA, GG vs. GA + AA, G vs. A, and AG vs. AA genetic models were estimated for each study. All of the genetic models indicated a statistically significant positive association with EC risk. The association appeared most pronounced for carriers of GG genotype (GG vs. AA: OR, 1.35; 95 % CI, 1.17 to 1.57), and weakest for individuals carrying GA genotype (GA vs. AA: OR, 1.13; 95 % CI, 1.05 to 1.23). Stratification analyses showed similar results in the population of Asians and in esophageal squamous cell carcinoma (ESCC). This meta-analysis provides strong statistical evidence for an elevated risk of EC associated with PLCE1 rs2274223. The association remains significant in Asian population and ESCC. Further investigations are warranted to validate these findings.

Abstract
Recent studies have shown association of mtDNA background with cancer development. We analyzed mitochondrial DNA (mtDNA) control region variation of 201 patients with nasopharyngeal carcinoma (NPC) and of 201 normal controls from Chaoshan Han Chinese to discern mtDNA haplogroup effect on the disease onset. Binary logistic regression analysis with adjustment for gender and age revealed that the haplogroup R9 (P = 0.011, OR = 1.91, 95% CI = 1.16-3.16), particularly its sub-haplogroup F1 (P = 0.015, OR = 2.43, 95% CI = 1.18-5.00), were associated significantly with increased NPC risk. These haplogroups were further confirmed to confer high NPC risk in males and/or individuals ≥ 40 years of age, but not in females or in subjects <40 years old. Our results indicated that mtDNA background confers genetic susceptibility to NPC in Chaoshan Han Chinese, and R9, particularly its sub-haplogroup F1, is a risk factor for NPC.

Abstract
Esophageal squamous cell carcinoma (ESCC) is one of most common malignant tumors in China, and the polymorphisms of genes associated with susceptibility to ESCC are important factors affecting individual tumor susceptibility. Genes associated with susceptibility to ESCC in Chinese Han population mainly contain metabolizing enzyme-associated genes, nucleotide excision repair genes, methylenetetrahydrofolate reductase gene, tumor suppressor genes, oncogenes, and cytokines. The genotypes of genes associated with susceptibility to ESCC have obvious regional distribution in Chinese Han population. This review aims to summarize and analyze the polymorphisms of genes associated with susceptibility to ESCC, including tumor suppressor genes and genes encoding oncogenes and cytokines, in Chinese Han population.

Abstract
Mitochondrial encephalopathy, lactic acidosis and stroke-like episodes (MELAS) are progressive neurodegenerative disorder associated with polygenetic, maternally inherited mutations in mitochondrial DNA. Approximately 80% of MELAS cases are caused by the mutation m.3243A>G of the mitochondrial tRNA(Leu (UUR)) gene (MT-TL1). We reported two probands with MELAS features. Muscle biopsy identified ragged-red fibers (RRF) in Gomori Trichrome staining. A respiratory chain function study showed decreased activity of mitochondrial respiratory chain complex I in both probands. Sequencing of the mitochondrial DNA revealed two novel MT-ND1 gene missense mutations, m.3959G>A and m.3995A>G, which are highly conserved among species. Protein secondary structure predictions demonstrated that these mutations may alter the peptide structure and may lead to decreased ND1 gene stability. Our findings suggest that these two novel mutations may contribute to the MELAS phenotypes of the patients in our study.

Abstract
BACKGROUND AND OBJECTIVE Two recent genome-wide association studies have identified a shared susceptibility variation PLCE1 rs2274223 for esophageal squamous cell carcinoma (ESCC) and gastric cardia adenocarcinomas (GCA). Subsequent case-control studies have reported this association in other populations. However, the findings were controversial and the effect remains undetermined. Our aim is to provide a precise quantification of the association between PLCE1 rs2274223 variation and the risk of ESCC and GCA. METHODS Studies were identified by a literature search in MEDLINE and EMBASE databases. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the association in allele, dominant, recessive, homozygous, and heterozygous models. RESULTS Ten articles were identified, including 22156 ESCC cases and 28803 controls, 5197 GCA cases and 17613 controls. Overall, PLCE1 rs2274223 G allele (G vs. A: OR=1.26, 95% CI: 1.15-1.39 for ESCC; OR=1.51, 95% CI: 1.35-1.69 for GCA) and its carrier (GG +AG vs. AA: OR = 1.23; 95% CI =1.02-1.49 for ESCC; OR =1.62; 95% CI =1.15-2.29 for GCA) were significantly associated with the risk of ESCC and GCA. In stratified analysis by ethnicity, significant association of PLCE1 rs2274223 G allele and the risk of ESCC (OR=1.33, 95% CI 1.21-1.45) and GCA (OR =1.56, 95% CI: 1.47-1.64) was observed in Chinese population. CONCLUSIONS Our meta-analysis results indicated that PLCE1 rs2274223 G allele significantly contributed to the risk of ESCC and GCA, especially in Chinese population.

Abstract
The Taihang Mountain range of north-central China, the Southern region area of Fujian province, and the Chaoshan plain of Guangdong province are 3 major regions in China well known for their high incidence of esophageal cancer (EC). These areas also exhibit high incidences of gastric cardia cancer (GCC). The ancestors of the Chaoshanese, now the major inhabitants in the Chaoshan plain, were from north-central China. We hypothesized that EC and GCC patients in Chaoshan areas share a common ancestry with Taihang Mountain patients. We analyzed 16 East Asian-specific Y-chromosome biallelic markers (single nucleotide polymorphisms; Y-SNPs) and 6 Y-chromosome short tandem repeat (Y-STR) loci in 72 EC and 48 GCC patients from Chaoshan and 49 EC and 63 GCC patients from the Taihang Mountain range. We also compared data for 32 Chaoshan Hakka people and 24 members of the aboriginal She minority who live near the Chaoshan area. Analysis was by frequency distribution and principal component, correlation and hierarchical cluster analysis of Y-SNP. Chaoshan patients were closely related to Taihang Mountain patients, even though they are geographically distant. Y-STR analysis revealed that the 4 patient groups were more closely related with each other than with other groups. Network analysis of the haplogroup O3a3c1-M117 showed a high degree of patient-specific substructure. We suggest that EC and GCC patients from these 2 areas share a similar patrilineal genetic background, which may play an important role in the genetic factor of EC and GCC in these populations.

Abstract
We investigated the rates of lipodystrophy events, according to mitochondrial DNA haplogroup, in 187 patients starting combination antiretroviral therapy and following it. Incidence rates of lipoatrophy and fat accumulation were 8.2 and 4.8 per 100 person-years of follow-up, respectively. In multivariable models, patients with haplogroup K were at higher risk of any lipodystrophy [adjusted relative risk (aRR) 4.02, P = 0.0009], lipoatrophy (competing-risk aRR 2.42, P = 0.09; cause-specific aRR 2.99, P = 0.031), and fat accumulation (competing-risk aRR, 2.63, P = 0.11; cause-specific aRR 5.27, P = 0.019) than those with haplogroup H. Mitochondrial haplogroups may explain part of the genetic predisposition to lipodystrophy during combination antiretroviral therapy.

Abstract
Mitochondria are the only organelles in animal cells which possess their own genomes. Mitochondrial DNA (mtDNA) alterations have been associated with various human conditions. Yet, their role in pathogenesis remains largely unclear. This review focuses on several major features of mtDNA: (1) mtDNA haplogroup, (2) mtDNA common deletion, (3) mtDNA mutations in the control region or D-loop, (4) mtDNA copy number alterations, (5) mtDNA mutations in translational machinery, (6) mtDNA mutations in protein coding genes (7) mtDNA heteroplasmy. We will also discuss their implications in various human diseases.

Abstract
BACKGROUND Excision repair cross complementing group 5 (ERCC5 or XPG) plays an important role in regulating DNA excision repair; its functional single nucleotide polymorphisms (SNPs) may alter DNA repair capacity and thus contribute to cancer risk. METHODOLOGY/PRINCIPAL FINDINGS In a hospital-based case-control study of 1115 esophageal squamous cell carcinoma (ESCC) cases and 1117 cancer-free controls, we genotyped three potentially functional SNPs of ERCC5 (SNPs, rs2296147T>C, rs2094258C>T and rs873601G>A) and estimated crude and adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for their associations with risk of ESCC using unconditional logistic regression models. We also calculated false-positive report probabilities (FPRPs) for significant findings. We found that compared with the TT genotype, ERCC5 rs2296147 C variant genotypes were associated with a significantly lower ESCC risk (CT: adjusted OR = 0.76, 95% CI = 0.63-0.93, CT/CC: adjusted OR = 0.80, 95% CI = 0.67-0.96); however, this risk was not observed for the other two SNPs (rs2094258C>T and rs873601 G>A), nor in further stratification and haplotype analysis. CONCLUSIONS/SIGNIFICANCES These findings suggested that ERCC5 polymorphisms may contribute to risk of ESCC in Eastern Chinese populations, but the effect was weak and needs further validation by larger population-based case-control studies.

Abstract
BACKGROUND A novel variant rs2274223 located in the phospholipase C epsilon 1 (PLCE1) gene was found to be associated with risk of esophageal squamous cell carcinoma (ESCC) by 2 large-scale genome-wide association studies (GWASs) in Chinese populations. In this study, we aimed to assess such an association in an eastern Chinese population and to address its possibly functional role in the etiology of ESCC. METHODS A total of 1061 ESCC cases and 1211 controls were recruited and successfully genotyped for 2 single nucleotide polymorphisms (SNPs) (rs2274223 and rs11187870) of the PLCE1 gene by the TaqMan assay. Real-time PCR and immunohistochemical (IHC) analysis were applied to assess mRNA and protein expression levels, respectively, in a subset of tumor samples. RESULTS SNP rs2274223 was independently associated with risk of ESCC (adjusted odds ratio [OR], 1.49; 95% confidence interval [95% CI], 1.03-2.17 for GG vs AA), and SNP rs11187870 was also found to be associated with risk of ESCC assuming a dominant model (adjusted OR, 1.20; 95% CI, 1.00-1.44 for CG/CC vs GG). The Grs2274223Crs11187870 haplotype increased the risk for ESCC by 1.22-fold (95% CI, 1.04-1.42). Further experiments showed that overall PLCE1 mRNA expression was lower in tumor than in paired normal tissues (0.067±0.016 vs 0.264±0.067, P<.05), and the IHC analysis showed the normal tissues of rs2274223 GG genotype had a lower PLCE1 staining score than that of the AG genotype (0.40±0.22 vs 1.33±0.32, P<.05). CONCLUSIONS PLCE1 SNP rs2274223 A>G change may reduce gene expression, and the variant G genotypes might contribute to risk of ESCC.

Abstract
Both the Taihang Mountain area in north-central China and Chaoshan area in the southeastern littoral of China are areas with high risk of esophageal cancer (EC). Our previous study confirmed that populations from the two areas might share similar matrilineal backgrounds and found that mitochondrial DNA (mtDNA) haplogroup D, especially subhaplogroups D4a and D5a, might be genetic background markers of EC in Chaoshan area. Here, to further determine whether D4a, D5a, and D might be susceptibility markers for EC in the two high-risk areas, we performed a case-control study with larger samples and analyzed the distributions of these three haplogroups in subjects (controls [n = 898] and patients [n = 768]) from the two areas. D4a haplogroup was significantly associated with increased risk of EC in Taihang Mountain subjects, especially women. D5 haplogroup was associated with EC at the general population level in the Taihang Mountain area and in subjects ≤ 60 years, especially women ≤ 60 years, in the Chaoshan area. D haplogroup was associated with EC only in subjects ≤ 60 years, especially men ≤ 60 years, in the Chaoshan area. D4a and D5 showing positive association with EC in the Taihang Mountain area became the predominant subhaplogroups of D in Chaoshan controls. In conclusion, D, D4a, and D5 haplogroups might be susceptibility markers for EC in the two high-risk areas in China, particularly D4a and D5 for the Taihang Mountain area and D and D5 for the Chaoshan area.

Abstract
BACKGROUND AND OBJECTIVES Incidence of Esophageal squamous cell carcinoma (ESCC) is prevalent in Asian populations, especially in the ones from the "Asian esophageal cancer belt" along the Silk Road and the ones from East Asia (including Japan). Silk Road and Eastern Asia population genetics are relevant to the ancient population migration from central China. The Arg47His (rs1229984) polymorphism of ADH1B is the highest in East Asians, and ancient migrations along the Silk Road were thought to be contributive to a frequent ADH1B*47His allele in Central Asians. This polymorphism was identified as responsible for susceptibility in the first large-scale genome-wide association study of ESCC and that's explained by its modulation of alcohol oxidization capability. To investigate the association of ADH1B Arg47His with ESCC in Asian populations under a common ancestry scenario of the susceptibility loci, we combined all available studies into a meta-analysis. METHODS A dataset composed of 4,220 cases and 8,946 controls from twelve studies of Asian populations was analyzed for ADH1B Arg47His association with ESCC and its interactions with alcohol drinking and ALDH2 Glu504Lys. Heterogeneity among studies and their publication bias were also tested. RESULTS The ADH1B*47Arg allele was found to be associated to increased risk of ESCC, with the odds ratios (OR) being 1.62 (95% CI: 1.49-1.76) and 3.86 (2.96-5.03) for the His/Arg and the Arg/Arg genotypes, respectively. When compared with the His/His genotype of non-drinkers, the Arg/Arg genotype can interact with alcohol drinking and greatly increase the risk of ESCC (OR = 20.69, 95%CI: 5.09-84.13). Statistical tests also showed gene-gene interaction of ADH1B Arg+ with ALDH2 Lys+ can bring more risk to ESCC (OR = 13.46, 95% CI: 2.32-78.07). CONCLUSION Revealed by this meta-analysis, ADH1B*47Arg as a common ancestral allele can significantly increase the risk of ESCC in Asians, especially when coupled with alcohol drinking or the ALDH2*504Lys allele.

Abstract
Background Mitochondrial DNA (mtDNA) haplogroups and single nucleotide polymorphisms (mtSNP) have been shown to play a role in various human conditions including aging and some neurodegenerative diseases, metabolic diseases and cancer. Methods To investigate whether mtDNA haplogroups contribute to the occurrence of cancer in a specific Chinese population, we have carried out a comprehensive case-control study of mtDNA from large cohorts of patients with three common cancer types, namely, colorectal cancer (n = 108), thyroid cancer (n = 100) and breast cancer (n = 104), in Wenzhou, a southern Chinese city in the Zhejiang Province. Results We found that patients with mtDNA haplogroup M exhibited an increased risk of breast cancer occurrence [OR = 1.77; 95% CI (1.03-3.07); P = 0.040], and that this risk was even more pronounced in a sub-haplogroup of M, D5 [OR = 3.11; 95%CI (1.07-9.06); p = 0.030]. In spite of this, in patients with breast cancer, haplogroup M was decreased in the metastatic group. On the other hand, our results also showed that haplogroup D4a was associated with an increased risk of thyroid cancer [OR = 3.00; 95%CI (1.09-8.29); p = 0.028]. However, no significant correlation has been detected between any mtDNA haplogroups and colorectal cancer occurrence. Conclusion Our investigation indicates that mitochondrial haplogroups could have a tissue-specific, population-specific and stage-specific role in modulating cancer development.

Abstract
Abnormal mitochondria have long been hypothesized to be involved in tumorigenesis. Mitochondrial DNA (mtDNA) mutations have been found in various cancer cells, yet their role in tumorigenesis remains largely unknown. Our long-term goal is to understand the role of mtDNA polymorphism and mtDNA mutations in tumorigenesis. We focused on the role of the mtDNA haplogroup; a 4,977 bp common mtDNA deletion; mtDNA mutations in the main control region of mtDNA or displacement loop; and mtDNA heteroplasmy in cancer occurrence and cancer development. Our results indicate that qualitative and quantitative changes in mtDNA play an important role in cancer development.

Abstract
About 40,000 inhabitants migrated from a high-risk area of esophageal squamous cell carcinoma (ESCC) to a low-risk area of esophageal cancer 40 years ago. Little is known about the change in the mortality in esophageal cancer among these immigrants. This study examined the impact of changing environments on esophageal cancer by comparing age-standardized mortality rates of immigrant group to the rates of native population (natives who live in high cancer location and have never moved) and host populations (hosts who live in low cancer location and have never moved people). All ESCC deaths taking place during 1999-2004 among the migrant, native, and host populations were identified by retrospective population-based screening. Direct age-adjusted mortality rates were calculated by using the China population of year 2000 as standard population. From 1999-2004, the average annual age-adjusted mortality of ESCC for the migrant, native, and host population was 61.6/100,000, 59.7/100,000, and 6.7/100,000, respectively. No decreasing tendency was found in mortality rate of ESCC in the population of young immigrants. The mortality rate of ESCC of migrants remained high even they had been living in the low endemic region for 40 years. This study strongly suggested that genetic susceptibility, rather than environment exposure, is responsible for the high risk of ESCC in the migrants.

Abstract
In this case-control study we evaluated contribution of environmental and genetic factors for risk of esophageal cancer (EC) by studying populations on Nanao Island (highest risk area for EC in China) and Shanwei (low risk region). Data on lifestyle, diet and family history were collected from the 166 newly diagnosed EC patients on Nanao between 2003 and 2004, from their 1450 first degree relatives and from controls on Nanao and Shanwei. Univariate and logistic regression analysis, family aggregation patterns, standardized incidence ratio (SIR), segregation ratio and heritability index were evaluated. The family cancer history was a significant risk factor for the two scenarios; Nanao cases versus Nanao controls, and Nanao controls versus Shanwei controls. Other risk factors included smoking, alcohol and fermented fish sauce. After adjusting for confounding variables, family history was independently associated with the occurrence of EC in Nanao cases versus Nanao controls. The incidence in the first degree relatives of Nanao cases was 0.86%, significantly higher than that of the public (0.12%) and SIR value was 1.44 in the first degree relatives of the 166 EC cases. The segregation ratio was 0.11 and the heritability index among first degree relatives was 40%. Our study indicates that there are steady pathogenic risk factors in the Nanao population's lifestyle but genetic factors also play an important role for EC onset.

Abstract
Previous studies showed that chromosomal instability was common in esophageal squamous cell carcinoma (ESCC); however, the mechanisms underlying this instability are unknown. Individuals with deficiencies in telomere maintenance are susceptible to enhanced telomere loss during cell proliferation; such deficiencies could result in telomere dysfunction and genomic instability. We investigated the association between genome-wide chromosomal changes in cancer cells and telomere length/attrition in cancer/stroma cells in 47 ESCC patients. Genome-wide detection of loss of heterozygosity was performed using the Affymetrix GeneChip single nucleotide polymorphism arrays. Telomere length was assessed separately for cancer cells, carcinoma-associated fibroblasts (CAF), infiltrative lymphocytes, and adjacent normal epithelial cells by quantitative fluorescent in situ hybridization using paraffin-embedded sections. Telomere length differed significantly among cell types, such that length in infiltrative lymphocytes > CAFs > cancer cells. Shortened telomeres were observed in cancer cells in 44 of 47 (94%) of the tumors examined. Telomere length in CAFs was significantly associated with chromosomal instability on 4q and 13q and lymphocyte telomere length was significantly associated with instability on chromosomal arms 15q. Although telomere length in cancer cells was not associated with chromosome arm instability, telomere attrition in cancer cells, defined as the telomere length in CAFs minus the telomere length in cancer cells, was significantly associated with chromosomal instability on 13q and 15q. This study provides evidence that telomere shortening is a common genetic alteration in ESCC and that chromosome arm instability is related to both telomere attrition in cancer cells and telomere length in tumor stroma cells.

Abstract
AIMS To investigate a possible association between mitochondrial haplogroups and non-arteritic anterior ischemic optic neuropathy (NAION). METHODS We compared the prevalence of various mitochondrial haplogroups in 24 NAION patients and 552 maternally unrelated ethnic controls. All patients and controls were Saudi Arabs. RESULTS NAION patients had substantially more potentially pathologic mtDNA nucleotide changes (10/24) than Controls (0/159) and a significantly elevated mean relative mtDNA content (2.62 +/- 1.21) than controls (1.33 +/- 0.34; p < or = 0.001). There was no statistically significant difference between patients and controls for any of the mitochondrial haplogroups tested. CONCLUSIONS Mitochondrial haplogroups do not appear to contribute to the pathogenesis of NAION in this cohort; however, mitochondrial abnormalities still seem likely to play a role.
