Abstract
Cancer, as a prevalent cause of mortality, poses a substantial global health burden and hinders efforts to enhance life expectancy. Nevertheless, the prognosis of patients with malignant tumors remains discouraging, owing to the lack of specific diagnostic and therapeutic targets. Therefore, the development of early diagnostic indicators and novel therapeutic drugs for the prevention and treatment of cancer is essential. Transmembrane proteins (TMEMs) are a class of proteins that can span the phospholipid bilayer and are stably anchored. They are associated with fibrotic diseases, neurodegenerative diseases, autoimmune diseases, developmental disorders, and cancer. It has been found that the expression levels of TMEMs were elevated or reduced in cancer cells, exerting pro/anticancer effects. These aberrant expression levels have also been linked to the prognostic and clinicopathological features of diverse tumors. In this review, the structures, functions, and roles of TMEMs in cancer were discussed, and the scientific perspectives were described. This review also explored the potential of TMEMs as tumor drug candidates from the perspective of targeted therapies, and the challenges that need to be overcome in a wide range of preclinical and clinical anticancer research were summarized.

Abstract
Autosomal dominant polycystic kidney disease (ADPKD) has cancer-like pathophysiology. In this study, we aimed to investigate the phenotype of peripheral blood (PB) T cell subsets and immune checkpoint inhibitor expression of ADPKD patients across different chronic kidney disease (CKD) stages. Seventy-two patients with ADPKD and twenty-three healthy controls were included in the study. The patients were grouped into five different CKD stages, according to glomerular filtration rate (GFR). PB mononuclear cells were isolated and T cell subsets and cytokine production were examined by flow cytometry. CRP levels, height-adjusted total kidney volume (htTKV), rate of hypertension (HT) differed significantly across different GFR stages in ADPKD. T cell phenotyping revealed significantly elevated CD3+ T cells, CD4+, CD8+, double-negative, and double-positive subsets and significantly elevated IFN-γ and TNF-α producing subsets of CD4+, CD8+ cells. The expression of checkpoint inhibitors CTLA-4, PD-1, and TIGIT by T cell subsets was also increased to various extent. Additionally, Treg cell numbers and suppressive markers CTLA-4, PD-1, and TIGIT were significantly elevated in ADPKD patients' PB. Treg CTLA4 expression and CD4CD8DP T cell frequency in patients with HT were significantly higher. Lastly, HT and increased htTKV and higher frequency of PD1+ CD8SP were found to be risk factors for rapid disease progression. Our data provide the first detailed analyses of checkpoint inhibitor expression by PB T cell subsets during stages of ADPKD, and that a higher frequency of PD1+ CD8SP cells is associated with rapid disease progression.

Abstract
INTRODUCTION This study aimed to determine whether miR-146a and miR-499 polymorphisms are associated with susceptibility to systemic lupus erythematosus (SLE). METHODS We searched the MEDLINE, EMBASE, and Cochrane databases. We performed a meta-analysis on the association of miR-146a rs2910164, rs2431697, rs57095329, and miR-499 rs3746444 polymorphisms with susceptibility to SLE. RESULTS Twenty-one studies from 17 reports, with 18,910 patients and 29,622 controls, were included in the meta-analysis. Meta-analysis revealed no association between SLE and the rs2910164 C allele (odds ratio [OR] = 0.999, 95% confidence interval [CI] = 0.816-1.222, p = 0.990). Stratification by ethnicity indicated no association between the miR-146a C allele and SLE in Arab or Latin American populations. The meta-analysis revealed an association between SLE and the miR-499 rs374644 CC + CT genotype in the overall group (OR = 1.313, 95% CI = 1.015-1.698, p = 0.038). Furthermore, meta-analysis revealed a significant association between SLE and the miR-146a rs2431697 C allele in the overall group (OR = 0.746, 95% CI = 0.697-0.798, p = 0.038). The miR-146a rs2431697 C allele is protective against SLE risk. Stratification by ethnicity indicated an association between the miR-146a rs2431697 C allele and SLE in Asian and European, but not Arab populations. The meta-analysis showed an association between the miR-146a rs57095329 G allele and SLE in Asian, but not Arab populations. DISCUSSION/CONCLUSION This meta-analysis suggests that the miR-146a rs2431697 polymorphism is a protective factor against the risk of SLE, and that the miR-146a rs57095329 and miR-499 rs3746444 polymorphisms are associated with susceptibility to SLE. However, miR-146a rs2910164 was not associated with susceptibility to SLE.

Noncoding RNA Res 2022; 7:142-149. [PMID: 35756164 PMCID: PMC9192690 DOI: 10.1016/j.ncrna.2022.05.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2021] [Revised: 05/21/2022] [Accepted: 05/22/2022] [Indexed: 11/28/2022] Open
Abstract
This study aimed to investigate the genetic polymorphisms of miR-146a SNPs (rs2910164, rs57095329, and rs2431697) in systemic lupus erythematosus (SLE) patients and their association with clinical manifestations. The implication of SNPs on miR-146a expression level was also evaluated. SLE patients (113) and healthy controls (104) were registered in this study. The miR-146a SNPs were genotyped by polymerase chain reaction/restriction fragment length polymorphism (PCR-RFLP). Quantitative real-time PCR was used to measure the miR-146a expression in peripheral blood mononuclear cells (PBMCs). Our results showed that the genotype frequency of miR-146a SNPs didn't deviate significantly from the Hardy–Weinberg equilibrium (HWE). The AG genotype and G allele of miR-146a (rs57095329 A/G) might be considered a risk factor for the disease (OR = 2.27; CI: 0.78–6.57 and OR: 2.35; CI: 0.79–6.92 for AG genotype and G allele, respectively). Although, no statistical significance in the distribution of miR-146a SNPs (rs2910164, rs57095329, and rs2431697) was found, indicating the lack of association between the three SNPs and SLE susceptibility. Significantly, the higher frequency of the AA genotype of miR-146a (rs57095329) was associated with pancytopenia (P < 0.05), while the CT genotype of miR-146a (rs2431697) was associated (P < 0.05) with the antiphospholipid syndrome (APS). SLE patients had significantly higher levels of miR-146a compared to controls (P < 0.05). Elevation of miR-146a was independent of any SNP genotypes. In conclusion, this pilot study shows no association between miR-146a SNPs in our population group and susceptibility to lupus. Studies concerning other miRNAs in larger sample sizes are essential for a better understanding of their role in susceptibility to SLE disease. This study is concerned with genetic polymorphisms of miR-146a in Lupus patients. The AG genotype and G allele of miR-146a (rs57095329 A/G) might be considered a risk factor. No significance in the distribution of miR-146a SNPs (rs2910164, rs57095329, and rs2431697). miR-146a level was significantly elevated in SLE irrespective to any SNP genotypes. AA genotype of rs57095329 was associated with pancytopenia while the CT genotype of rs2431697 was associated with the APS.

Abstract
Despite strong evidence that human genetic variants affect the expression of many key transcription factors involved in autoimmune diseases, establishing biological links between non-coding risk variants and the gene targets they regulate remains a considerable challenge. Here, we combine genetic, epigenomic, and CRISPR activation approaches to screen for functional variants that regulate IRF8 expression. We demonstrate that the locus containing rs2280381 is a cell-type-specific enhancer for IRF8 that spatially interacts with the IRF8 promoter. Further, rs2280381 mediates IRF8 expression through enhancer RNA AC092723.1, which recruits TET1 to the IRF8 promoter regulating IRF8 expression by affecting methylation levels. The alleles of rs2280381 modulate PU.1 binding and chromatin state to regulate AC092723.1 and IRF8 expression differentially. Our work illustrates an integrative strategy to define functional genetic variants that regulate the expression of critical genes in autoimmune diseases and decipher the mechanisms underlying the dysregulation of IRF8 expression mediated by lupus risk variants.

Abstract
OBJECTIVE To investigated the association between single nucleotide polymorphisms (SNPs) in microRNA-146a (miR-146a) gene and susceptibility of rheumatoid arthritis (RA). METHODS We systemically extracted the genetic data of miR-146a from previous genome-wide association studies (GWASs) of RA. Subsequently, we performed a replication study in an independent Chinese cohort for selected variant. A meta-analysis combined the previous GWASs with the replication study was also conducted. The epigenetic annotation and cytokine assay were used for exploring potential variant function. RESULTS The extracted genetic association data from three previous GWASs showed that the allele T of functional SNP rs2431697 increased RA susceptibility. The significant association for the SNP was also found in the Chinese replication cohort (OR = 1.24, 95% CI = 1.06-1.46, p = 8.69E-03). The estimated effect size for this SNP was larger in Asian population than that in European population (Asian meta-analysis: OR = 1.15, 95% CI = 1.09-1.22, p = 4.37E-07; Tran-ethnic meta-analysis: OR = 1.07, 95% CI = 1.04-1.10, p = 1.79E-06). The cytokine assay also showed that the risk allele T of the SNP rs2431697 is inversely associated with plasma TNF-α levels in health controls (p = .016). CONCLUSIONS In summary, this study supports that genetic variant in miR-146a gene is associated with RA risk.KEY MESSAGESThe association between SNPs in miR-146a gene and susceptibility of RA was unclear.We investigated the genetic association using GWASs data and a replication study.The SNP rs2431697 in miR-146a gene is associated with RA risk.

Abstract
Purpose Various studies have shown an association between miRNA polymorphisms and susceptibility to autoimmune disease (AD); however, the results are inconclusive. To evaluate whether miRNA polymorphisms account for a significant risk of AD, a total of 87 articles, including 39431 patients and 56708 controls, were identified to estimate their association with 12 AD subtypes. Methods Several electronic databases were searched to analyze population-based studies on the relationship between miRNA variants and AD risk. Fixed effects or random effect models were used in the meta-analysis for the risk assessment. Results In our meta-analysis, miR-146a rs2910164/rs57095329 conferred a marginally elevated risk for AD (allele model, OR = 1.08, 95% CI: 1.01-1.15, P = 0.019; allele model, OR = 1.09, 95 CI: 1.05-1.15, P < 0.001, respectively). Furthermore, miR-196a2 rs11614913 was also associated with AD risk (allele model, OR = 0.92, 95% CI: 0.88-0.97, P = 0.001) as well as miR-499 rs3746444 (allele model, OR = 1.16, 95% CI: 1.03-1.29, P = 0.011). In addition, associations were observed between miR-149 rs2292832/miR-27a rs895819 and AD susceptibility in the overall population (allele model, OR = 1.15, 95% CI: 1.06-1.24, P < 0.001; allele model, OR = 1.11, 95% CI:1.01-1.22, P = 0.043, respectively). Conclusions Evidence from our systematic review suggests that miR-146a, miR-196a2, miR-499, miR-149, and miR-27a polymorphisms are associated with susceptibility to AD.

Abstract
The publication of genetic epidemiology meta-analyses has increased rapidly, but it has been suggested that many of the statistically significant results are false positive. In addition, most such meta-analyses have been redundant, duplicate, and erroneous, leading to research waste. In addition, since most claimed candidate gene associations were false-positives, correctly interpreting the published results is important. In this review, we emphasize the importance of interpreting the results of genetic epidemiology meta-analyses using Bayesian statistics and gene network analysis, which could be applied in other diseases.

Abstract
Immune thrombotic thrombocytopenic purpura (iTTP) is an ultra-rare, life-threatening disorder, mediated through severe ADAMTS13 deficiency causing multi-system micro-thrombi formation, and has specific human leukocyte antigen associations. We undertook a large genome-wide association study to investigate additional genetically distinct associations in iTTP. We compared two iTTP patient cohorts with controls, following standardized genome-wide quality control procedures for single-nucleotide polymorphisms and imputed HLA types. Associations were functionally investigated using expression quantitative trait loci (eQTL), and motif binding prediction software. Independent associations consistent with previous findings in iTTP were detected at the HLA locus and in addition a novel association was detected on chromosome 3 (rs9884090, P=5.22x10-10, odds ratio 0.40) in the UK discovery cohort. Meta-analysis, including the French replication cohort, strengthened the associations. The haploblock containing rs9884090 is associated with reduced protein O-glycosyltransferase 1 (POGLUT1) expression (eQTL P<0.05), and functional annotation suggested a potential causative variant (rs71767581). This work implicates POGLUT1 in iTTP pathophysiology and suggests altered post-translational modification of its targets may influence disease susceptibility.

Genetic variants of microRNA-146a gene: an indicator of systemic lupus erythematosus susceptibility, lupus nephritis, and disease activity. Mol Biol Rep 2020; 47:7459-7466. [PMID: 32929657 DOI: 10.1007/s11033-020-05802-y] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2020] [Accepted: 09/03/2020] [Indexed: 12/12/2022]
Abstract
Genetic variations of microRNA encoding genes influence various sorts of diseases by modifying the expression or activity of microRNAs. MicroRNA 146a is an epigenetic regulator of immune response through controlling the type I interferon (IFN) and nuclear factor kappa B (NF-κB) pathways. Genetic variations of microRNA 146a impact the susceptibility to systemic lupus erythematosus (SLE) and its clinical presentations. This study aimed to investigate the polymorphisms of microRNA-146a gene (rs2431697 and rs57095329) in patients with SLE and its association with disease activity. Sixty-five patients with SLE and 40 apparently healthy controls were enrolled in this study. Patients were subjected to history taking, clinical examination, and disease activity evaluation by SLEDAI score. The microRNA-146a variants were determined by allele discrimination real-time PCR method in all participants. We found a statistically significant association between rs2431697 T allele and SLE (P-value < 0.05), but there was no significant association between rs57095329 and SLE. The T/T genotype of microRNA-146a rs2431697 was associated with lupus nephritis, higher disease activity, and autoantibodies production. The microRNA-146a rs2431697 T allele could be a potential risk factor that contributes to SLE susceptibility, development of lupus nephritis, and disease activity.

Abstract
Encephalomyocarditis virus (EMCV) causes encephalitis, myocarditis, neuropathy, reproductive disorders, and diabetes in animals. EMCV is known to induce cell autophagy; however, the molecular mechanisms underlying this remain unclear. Here, we show that the type III-transmembrane protein, transmembrane protein 39A (TMEM39A), plays a critical role in EMCV replication. We showed that EMCV GS01 strain infection upregulated TMEM39A expression. Importantly, EMCV induced autophagy in a range of host cells. The autophagy chemical inhibitor, 3-MA, inhibited EMCV replication and reduced TMEM39A expression. This is the first study demonstrating TMEM39A promoting the replication of EMCV via autophagy. Overall, we show that TMEM39A plays a positive regulatory role in EMCV proliferation and that TMEM39A expression is dependent on the autophagy pathway.

Abstract
Transmembrane protein 39A (TMEM39A) gene polymorphisms have been related to various autoimmune diseases, but the relationship between TMEM39A polymorphisms and autoimmune thyroid disease (AITD) remains unknown. This study was aimed at investigating whether the polymorphisms of the TMEM39A were associated with AITD in the Chinese Han population. A case-control study was performed in a total of 906 AITD patients and 744 healthy controls. Four single nucleotide polymorphisms, including rs1132200, rs12492609, rs2282175, and rs7629750, in TMEM39A were examined by polymerase chain reaction-ligase detection reaction. We found that the allele T of rs12492609 in TMEM39A was associated with AITD and Hashimoto's thyroiditis (HT) (p = 0.023; p = 0.028 respectively). Compared with controls, the frequency of haplotype CCA in AITD patients was higher than that in controls (p = 0.036), but the frequency of haplotype CTA in AITD and HT patients was lower than that in controls (p = 0.046; p = 0.047 respectively). In addition, the frequency of allele A at rs7629750 in AITD patients with onset age ≤18 years old was higher than that in AITD patients with onset age ≥19 (p = 0.046). Further, there was an obvious difference in the genotype distributions of rs12492609 and rs7629750 between HT patients with hypothyroidism and those without hypothyroidism (p = 0.034 and p = 0.023, respectively). Our study first reveals that the polymorphisms of the TMEM39A gene are associated with the susceptibility to AITD, especially for early-onset AITD and HT with hypothyroidism.

Abstract
Systemic lupus erythematosus (SLE) is characterized by aberrant production of
auto-antibodies and a sexual dimorphism both in the phenotypic expression and
frequency of the disease between males and females. The striking female
predominance was initially attributed primarily to sex hormones. However, recent
data challenge this simplistic view and point more towards genetic and
epigenetic factors accounting for this difference. More specifically, several
SLE-associated single-nucleotide polymorphisms (SNPs) have been found to play an
important role in the gender predilection in SLE. Their effect is mediated
through their involvement in sex-hormone and immune system signalling and
dysregulation of the expression of genes and miRNAs pertinent to the immune
system. Additionally, the genetic factors are interchangeably associated with
epigenetic modifications such as DNA methylation and histone modification, thus
revealing a highly complex network of responsible mechanisms. Of importance,
disturbance in the epigenetic process of X chromosome inactivation in females as
well as in rare X chromosome abnormalities leads to increased expression of
X-linked immune-related genes and miRNAs, which might predispose females to SLE.
Microbiota dysbiosis has also been implicated in the sexual dimorphism by the
production of oestrogens within the gut and the regulation of
oestrogen-responsive immune-related genes. Sexual dimorphism in SLE is an area
of active research, and elucidation of its molecular basis may facilitate
ongoing efforts towards personalized care.

Abstract
Systemic lupus erythematosus (SLE) is a chronic heterogeneous autoimmune disease characterized by loss of tolerance to self-antigens, complement activation, dysregulated type 1 IFN responses, and immune-mediated tissue damage. The clinical features of SLE are pleomorphic, affecting virtually any organ system, such as skin, joints, central nervous system, or kidneys. Currently, the etiology and pathogenesis of SLE are not fully understood. Generally, it is considered that genetic factors, immune abnormalities, sex hormones, and environmental factors are associated with SLE, and mainly caused by genetic and environmental interactions, typical for a complex disease with multiple susceptibility genes. Therefore, identification of SLE susceptibility loci through molecular genetics methods may help build the foundation for identifying individuals and groups susceptible to SLE, early prevention, new drug development, and individualized treatment promoting precision medicine.

Abstract
MicroRNAs (miRNAs) are small non-coding RNA molecules that negatively regulate the expression of multiple protein-encoding genes at the post-transcriptional level. MicroRNAs are involved in different pathways, such as cellular proliferation and differentiation, signal transduction and inflammation, and play crucial roles in the development of several diseases, such as cancer, diabetes, and cardiovascular diseases. They have recently been recognized to play a role also in the pathogenesis of autoimmune diseases. Although the majority of studies are focused on miRNA expression profiles investigation, a growing number of studies have been investigating the role of polymorphisms in miRNA genes in the autoimmune diseases development. Indeed, polymorphisms affecting the miRNA genes can modify the set of targets they regulate or the maturation efficiency. This review is aimed to give an overview about the available studies that have investigated the association of miRNA gene polymorphisms with the susceptibility to various autoimmune diseases and to their clinical phenotypes.

Abstract
The etiology of autoimmune diseases is due to a combination of genetic predisposition and environmental factors that alter the expression of immune regulatory genes through various mechanisms including epigenetics. Both humoral and cellular elements of the adaptive immune system play a role in the pathogenesis of autoimmune diseases and the presence of autoantibodies have been detected in most but not all autoimmune diseases before the appearance of clinical symptoms. In some cases, the presence or levels of these autoantibodies portends not only the risk of developing a corresponding autoimmune disease, but occasionally the severity as well. This observation is intriguing because it suggests that we can, to some degree, predict who may or may not develop autoimmune diseases. However, the role of autoantibodies in the pathogenesis of autoimmune diseases, whether they actually affect disease progression or are merely an epiphenomenon is still not completely clear in many autoimmune diseases. Because of these gaps in our knowledge, the ability to accurately predict a future autoimmune disease can only be considered a relative risk factor. Importantly, it raises the critical question of defining other events that may drive a patient from a preclinical to a clinical phase of disease.

Abstract
Transmembrane Protein 39A (TMEM39A) is a member of TMEM family. The understanding about this protein is still limited. The earlier studies indicated that TMEM39A was a key mediator of autoimmune disease. TMEM39A seems to be involved in systemic lupus erythematosus and multiple sclerosis in numerous of populations. All of these works stop at insufficient information by using gene functioning methods such as: Genome-wide association studies (GWASs) and/or follow-up study. It is the fact that the less understood of TMEM39A actually is the attraction to the scientist in near future. In this review the current knowledge about TMEM39A and its possible roles in cell biology, physiology and pathology will be described.

Abstract
The carboxyl terminal of Hsp70-interacting protein (CHIP) is an E3 ubiquitin ligase that plays a pivotal role in the protein quality control system by shifting the balance of the folding-refolding machinery toward the degradative pathway. However, the precise mechanisms by which nonnative proteins are selected for degradation by CHIP either directly or indirectly via chaperone Hsp70 or Hsp90 are still not clear. In this review, we aim to provide a comprehensive model of the mechanism by which CHIP degrades its substrate in a chaperone-dependent or direct manner. In addition, through tight regulation of the protein level of its substrates, CHIP plays important roles in many physiological and pathological conditions, including cancers, neurological disorders, cardiac diseases, bone metabolism, immunity, and so on. Nonetheless, the precise mechanisms underlying the regulation of the immune system by CHIP are still poorly understood despite accumulating developments in our understanding of the regulatory roles of CHIP in both innate and adaptive immune responses. In this review, we also aim to provide a view of CHIP-mediated regulation of immune responses and the signaling pathways involved in the model described. Finally, we discuss the roles of CHIP in immune-related diseases.

Abstract
Genome-wide association studies (GWAS) have identified hundreds of new potential genetic risk loci associated with numerous complex diseases such as multiple sclerosis (MS). Genes which have been discovered by GWAS are now the focus of numerous ongoing studies. The goal of this study was to confirm and understand the potential role of one of such genes—transmembrane protein 39A gene (TMEM39A)—in multiple sclerosis. We showed the difference in TMEM39A messenger RNA (mRNA) expression between MS patients and controls (T22;74 = 5.429; p = 0.0063). In our study, the lower mRNA expression of TMEM39A gene in patients did not correlate with a higher methylation level of the TMEM39A promoter. Moreover, a decreased level of TMEM39A mRNA was associated neither with rs1132200 nor with rs17281647. Additionally, we did not find an association between these two TMEM39A polymorphisms and the risk and progression of multiple sclerosis. Our investigation is the first which indicates that TMEM39A mRNA expression may be associated with the development and/or course of multiple sclerosis.

Abstract
BACKGROUND This study aimed to assess the association between 14 single nucleotide polymorphisms (SNPs) in six genes (IRF8, TMEM39A, IKZF3, ORMDL3, GSDMB, and ZPBP2) and systemic lupus erythematosus (SLE) in a Chinese Han population sample. METHODS We carried out a case-control study of 415 patients with SLE and 470 healthy controls without autoimmune disease or cancer. DNA for genetic analysis was isolated from the blood of all subjects using standard phenol-chloroform method. TagSNPs were identified using genotype data from the panel (Han Chinese in Beijing) of the HapMap Project and were selected using the Haploview program. Genotyping assay was conducted using the Sequenom MassARRAY iPLEX Gold platform. The frequencies of the alleles and genotypes were calculated and analyzed. Association studies and haplotype analysis were also performed. RESULTS The genotypic frequencies of rs12493175 and rs13062955 were significantly different between the SLE patients and the healthy controls. Compared with the common homozygous genotype, the CT and CT + TT genotypes in rs12493175 and the AC and AC + AA genotypes in rs13062955 was observed to significantly reduce the risk of SLE. The haplotype analysis of TMEM39A polymorphisms showed that the CGTA haplotype frequency was significantly low in the SLE patients. CONCLUSION Our findings identified three novel associations in SNPs located in the TMEM39A gene associated with SLE susceptibility in a Chinese Han population.

Abstract
Systemic lupus erythematosus (SLE) is a complex disorder. Genetic association studies of complex disorders suffer from the following three major issues: phenotypic heterogeneity, false positive (type I error), and false negative (type II error) results. Hence, genes with low to moderate effects are missed in standard analyses, especially after statistical corrections. OASIS is a novel linkage disequilibrium clustering algorithm that can potentially address false positives and negatives in genome-wide association studies (GWAS) of complex disorders such as SLE. OASIS was applied to two SLE dbGAP GWAS datasets (6077 subjects; ∼0.75 million single-nucleotide polymorphisms). OASIS identified three known SLE genes viz. IFIH1, TNIP1, and CD44, not previously reported using these GWAS datasets. In addition, 22 novel loci for SLE were identified and the 5 SLE genes previously reported using these datasets were verified. OASIS methodology was validated using single-variant replication and gene-based analysis with GATES. This led to the verification of 60% of OASIS loci. New SLE genes that OASIS identified and were further verified include TNFAIP6, DNAJB3, TTF1, GRIN2B, MON2, LATS2, SNX6, RBFOX1, NCOA3, and CHAF1B. This study presents the OASIS algorithm, software, and the meta-analyses of two publicly available SLE GWAS datasets along with the novel SLE genes. Hence, OASIS is a novel linkage disequilibrium clustering method that can be universally applied to existing GWAS datasets for the identification of new genes.

Abstract
Transmembrane protein 39A (TMEM39A) belongs to the TMEM39 family. TMEM39A gene is a susceptibility locus for multiple sclerosis. In addition, TMEM39A seems to be implicated in systemic lupus erythematosus. However, any possible involvement of TMEM39A in cancer remains largely unknown. In the present report, we provide evidence that TMEM39A may play a role in brain tumors. Western blotting using an anti-TMEM39A antibody indicated that TMEM39A was overexpressed in glioblastoma cell lines, including U87-MG and U251-MG. Deep-sequencing transcriptomic profiling of U87-MG and U251-MG cells revealed that TMEM39A transcripts were upregulated in such cells compared with those of the cerebral cortex. Confocal microscopic analysis of U251-MG cells stained with anti-TMEM39A antibody showed that TMEM39A was located in dot-like structures lying close to the nucleus. TMEM39A probably located to mitochondria or to endosomes. Immunohistochemical analysis of glioma tissue specimens indicated that TMEM39A was markedly upregulated in such samples. Bioinformatic analysis of the Rembrandt knowledge base also supported upregulation of TMEM39A mRNA levels in glioma patients. Together, the results afford strong evidence that TMEM39A is upregulated in glioma cell lines and glioma tissue specimens. Therefore, TMEM39A may serve as a novel diagnostic marker of, and a therapeutic target for, gliomas and other cancers.

Abstract
Systemic lupus erythematosus (SLE; OMIM 152700) is a genetically complex autoimmune disease. Genome-wide association studies (GWASs) have identified more than 50 loci as robustly associated with the disease in single ancestries, but genome-wide transancestral studies have not been conducted. We combined three GWAS data sets from Chinese (1,659 cases and 3,398 controls) and European (4,036 cases and 6,959 controls) populations. A meta-analysis of these studies showed that over half of the published SLE genetic associations are present in both populations. A replication study in Chinese (3,043 cases and 5,074 controls) and European (2,643 cases and 9,032 controls) subjects found ten previously unreported SLE loci. Our study provides further evidence that the majority of genetic risk polymorphisms for SLE are contained within the same regions across both populations. Furthermore, a comparison of risk allele frequencies and genetic risk scores suggested that the increased prevalence of SLE in non-Europeans (including Asians) has a genetic basis.

Abstract
Systemic lupus erythematosus (SLE) is a chronic autoimmune disease caused by complex interactions between genes and the environment. The expression level of transcription factor regulatory factor X 1 (RFX1) is reduced in T cells from SLE patients. RFX1 can regulate epigenetic modifications of CD70 and CD11a and plays an important role in the development of SLE. However, the mechanisms that mediate reduction of RFX1 in SLE are unclear. Here, we demonstrate that RFX1 protein expression can be tightly regulated by polyubiquitination-mediated proteosomal degradation via STIP1 homology and U-box containing protein 1 (STUB1). The E3 ligase STUB1 is upregulated in CD4(+)T cells of SLE patients compared to healthy subjects. Overexpression of STUB1 in CD4(+)T cells leads to upregulation of levels of CD70 and CD11a in T cells. The modulation of STUB1 activity may provide a novel therapeutic approach for SLE.

Abstract
We aimed to elucidate the cell types, tissues, and pathways influenced by common variants in systemic lupus erythematosus (SLE). We applied a nonparameter enrichment statistical approach, termed SNPsea, in 181 single nucleotide polymorphisms (SNPs) that have been identified to be associated with the risk of SLE through genome-wide association studies (GWAS) in Eastern Asian and Caucasian populations, to manipulate the critical cell types, tissues, and pathways. In the two most significant cells’ findings (B lymphocytes and CD14+ monocytes), we subjected the GWAS association evidence in the Han Chinese population to an enrichment test of expression quantitative trait locus (QTL) sites and DNase I hypersensitivity, respectively. In both Eastern Asian and Caucasian populations, we observed that the expression level of SLE GWAS implicated genes was significantly elevated in xeroderma pigentosum B cells (P ≤ 1.00 × 10−6), CD14+ monocytes (P ≤ 2.74 × 10−4) and CD19+ B cells (P ≤ 2.00 × 10−6), and plasmacytoid dendritic cells (pDCs) (P ≤ 9.00 × 10−6). We revealed that the SLE GWAS-associated variants were more likely to reside in expression QTL in B lymphocytes (q1/q0 = 2.15, P = 1.23 × 10−44) and DNase I hypersensitivity sites (DHSs) in CD14+ monocytes (q1/q0 = 1.41, P = 0.08). We observed the common variants affected the risk of SLE mostly through by regulating multiple immune system processes and immune response signaling. This study sheds light on several immune cells and responses, as well as the regulatory effect of common variants in the pathogenesis of SLE.
