Abstract
OBJECTIVE At present, little is known about the immune mechanism of liver transplantation caused by decompensated cirrhosis. Lymphocytes play an essential important role in the immune rejection of liver transplantation. In this study, we aimed to comprehensively analyze changes in complementary determinant 3 (CDR3) repertoire of T cell receptor β chain (TRβ) and immunoglobulin heavy chain (IGH) in liver transplantation patients and healthy controls (HC). METHODS High-throughput sequencing technology was used to study the characteristics of TRβ/IGH CDR3 repertoire, and identify the amino acid sequences of TRβ and IGH associated with liver transplantation patients and HC. RESULTS We found that some TRβ and IGH CDR3 repertoire characteristics differed between liver transplant patients and HC. The diversity of TRβ CDR3 increased in the liver transplantation group. First and seven days after live transplantation patients showed a lower degree of T cell clone amplification compared to the HC group. The CDR3 repertoire of the TRβ/IGH chain was certainly biased in the use of some V, D, and J gene segments, TRβ/IGH V-J combined frequency was also skewed and TRβ CDR3 clonotypes were shared at a higher degree in the liver transplantation patients. Importantly, one amino acid sequence in the decompensated cirrhosis group was significantly higher than that in the healthy group. It should be noted that the frequency of some CDR3 sequences is closely correlated with the different stages of liver transplantation, and these sequences may play a key role in liver transplantation. CONCLUSION Based on the above results, we can better understand the dynamic changes of TCβ/IGH CDR3 repertoire in patients during liver transplantation.

Abstract
Human pluripotent stem cell-derived islets (hPSC islets) are a promising alternative to primary human islets for the treatment of insulin-deficient diabetes. We previously demonstrated the feasibility of this approach in nonhuman primates; however, the therapeutic effects of hPSC islets can be limited by the maladaptive processes at the transplantation site. Here, we demonstrate successful implantation of hPSC-derived islets in a new transplantation site in the abdomen, the subanterior rectus sheath, in eight nonhuman primates (five male and three female). In this proof-of-principle study, we find that hPSC islets survive and gradually mature after transplantation, leading to improved glycemic control in diabetic primates. Notably, C-peptide secretion responds to meal challenge from 6 weeks post-transplantation (wpt), with stimulation indices comparable to those of native islets. The average post-prandial C-peptide level reaches approximately 2.0 ng ml-1 from 8 wpt, which is five times higher than the peak value we previously obtained after portal vein infusion of hPSC islets and was associated with a decrease of glycated hemoglobin levels by 44% at 12 wpt. Although additional studies in larger cohorts involving long-term follow-up of transplants are needed, our results indicate that the subanterior rectus sheath supports functional maturation and maintenance of hPSC islets, suggesting that it warrants further exploration as a transplantation target site in the context of for hPSC-based cell-replacement therapies.

Abstract
PURPOSE Membranous nephropathy (MN) is a common cause of nephrotic syndrome in adults. However, the underlying mechanisms of its occurrence and development are not completely clear. Thus, it is essential to explore the mechanisms. EXPERIMENTAL DESIGN Here, we employed label-free quantification and liquid chromatography-tandem mass spectrometry analysis techniques to investigate the proteomic and phosphoproteomic alterations in renal biopsy tissues of MN patients. Samples were collected from 16 MN patients and 10 controls. Immunohistochemistry (IHC) was performed to validate the hub phosphoprotein. RESULTS We focused on the changes in the phosphoproteome in MN group versus control group (CG). Totally, 1704 phosphoproteins containing 3241 phosphosites were identified and quantified. The phosphorylation levels of 216 phosphoproteins containing 297 phosphosites were differentially regulated in stage II MN group versus CG, and 333 phosphoproteins containing 461 phosphosites were differentially phosphorylated in stage III MN group versus CG. In each comparison, several differential phosphoproteins were factors, kinases and receptors involved in cellular processes, biological regulation and other biological processes. The subcellular location of most of the differential phosphoproteins was the nucleus. Protein-protein interaction analysis showed that the connections among the differential phosphoproteins were extremely complex, and several signalling pathways probably associated with MN were identified. The hub phosphoprotein was validated by IHC. CONCLUSIONS AND CLINICAL RELEVANCE This investigation can provide direct insight into the global phosphorylation events in MN group versus CG and may help to shed light on the potential pathogenic mechanisms of MN.

Abstract
BACKGROUND Immune aberrations in end-stage renal disease (ESRD) are characterized by systemic inflammation and immune deficiency. The mechanistic understanding of this phenomenon remains limited. METHODS We generated 12 981 and 9578 single-cell transcriptomes of peripheral blood mononuclear cells (PBMCs) that were pooled from 10 healthy volunteers and 10 patients with ESRD by single-cell RNA sequencing. Unsupervised clustering and annotation analyses were performed to cluster and identify cell types. The analysis of hallmark pathway and regulon activity was performed in the main cell types. RESULTS We identified 14 leukocytic clusters that corresponded to six known PBMC types. The comparison of cells from ESRD patients and healthy individuals revealed multiple changes in biological processes. We noticed an ESRD-related increase in inflammation response, complement cascade and cellular metabolism, as well as a strong decrease in activity related to cell cycle progression in relevant cell types in ESRD. Furthermore, a list of cell type-specific candidate transcription factors (TFs) driving the ESRD-associated transcriptome changes was identified. CONCLUSIONS We generated a distinctive, high-resolution map of ESRD-derived PBMCs. These results revealed cell type-specific ESRD-associated pathways and TFs. Notably, the pooled sample analysis limits the generalization of our results. The generation of larger single-cell datasets will complement the current map and drive advances in therapies that manipulate immune cell function in ESRD.

Abstract
The aim of this study was to identify novel genetic variants affecting tacrolimus trough blood concentrations. We analyzed the association between 58 single nucleotide polymorphisms (SNPs) across the CYP3A gene cluster and the log-transformed tacrolimus concentration/dose ratio (log (C0/D)) in 819 renal transplant recipients (Discovery cohort). Multivariate linear regression was used to test for associations between tacrolimus log (C0/D) and clinical factors. Luciferase reporter gene assays were used to evaluate the functions of select SNPs. Associations of putative functional SNPs with log (C0/D) were further tested in 631 renal transplant recipients (Replication cohort). Nine SNPs were significantly associated with tacrolimus log (C0/D) after adjustment for CYP3A5*3 and clinical factors. Dual luciferase reporter assays indicated that the rs4646450 G allele and rs3823812 T allele were significantly associated with increased normalized luciferase activity ratios (p < 0.01). Moreover, CYP3A7*2 was associated with higher TAC log(C0/D) in the group of CYP3A5 expressers. Age, serum creatinine and hematocrit were significantly associated with tacrolimus log (C0/D). CYP3A7*2, rs4646450, and rs3823812 are proposed as functional SNPs affecting tacrolimus trough blood concentrations in Chinese renal transplant recipients. Clinical factors also significantly affect tacrolimus metabolism.

Abstract
Background Kidneys obtained from deceased donors increase the incidence of delayed graft function (DGF) after renal transplantation. Here we investigated the influence of the risk factors of donors with DGF, and developed a donor risk scoring system for DGF prediction. Methods This retrospective study was conducted in 1807 deceased kidney donors and 3599 recipients who received donor kidneys via transplants in 29 centers in China. We quantified DGF associations with donor clinical characteristics. A donor risk scoring system was developed and validated using an independent sample set. Results The incidence of DGF from donors was 19.0%. Six of the donor characteristics analyzed, i.e., age, cause of death, history of hypertension, terminal serum creatinine, persistence of hypotension, and cardiopulmonary resuscitation (CPR) time were risk factors for DGF. A 49-point scoring system of donor risk was established for DGF prediction and exhibited a superior degree of discrimination. External validation of DGF prediction revealed area under the receiver-operating characteristic (AUC) curves of 0.7552. Conclusions Our study determined the deceased donor risk factors related to DGF after renal transplantation pertinent to the Chinese cohort. The scoring system developed here had superior diagnostic significance and consistency and can be used by clinicians to make evidence-based decisions on the quality of kidneys from deceased donors and guide renal transplantation therapy.

Abstract
Human induced pluripotent stem cells (iPSCs) are important source for regenerative medicine. However, the links between pluripotency and oncogenic transformation raise safety issues. To understand the characteristics of iPSC-derived cells at single-cell resolution, we directly reprogrammed two human iPSC lines into cardiomyocytes and collected cells from four time points during cardiac differentiation for single-cell sequencing. We captured 32,365 cells and identified five molecularly distinct clusters that aligned well with our reconstructed differentiation trajectory. We discovered a set of dynamic expression events related to the upregulation of oncogenes and the decreasing expression of tumor suppressor genes during cardiac differentiation, which were similar to the gain-of-function and loss-of-function patterns during oncogenesis. In practice, we characterized the dynamic expression of the TP53 and Yamanaka factor genes (OCT4, SOX2, KLF4 and MYC), which were widely used for human iPSCs lines generation; and revealed the co-occurrence of MYC overexpression and TP53 silencing in some of human iPSC-derived TNNT2+ cardiomyocytes. In summary, our oncogenic expression atlas is valuable for human iPSCs application and the single-cell resolution highlights the clues potentially associated with the carcinogenic risk of human iPSC-derived cells. Summary: The single-cell expression atlas in the cardiomyocytes generated from human iPSCs provide potential carcinogenic information for the clinical application of human iPSC-derived cells.

Abstract
Hepatocellular carcinoma (HCC) is one of the most lethal malignancies that is closely associated with the Hepatitis B virus (HBV). HBV integration into host genomes can induce instability and the aberrant expression of human genomic DNA. To directly assess HBV integration breakpoints at whole genome level, four small sequencing libraries were constructed and the HBV integration profiles of four patients with HCC were characterized. In total, the current study identified 11,800,974, 11,216,998, 11,026,546 and 11,607,842 clean reads for patients 1-3 and 4, respectively, of which 92.82, 95.95, 97.21 and 97.29% were properly aligned to the hybrid reference genome. In addition, 220 HBV integration events were detected from the tumor tissues of four patients with HCC and an average of 55 breakpoints per sample was calculated. The results indicated that HBV integration events may be implicated in HCC physiologies and diseases. The results acquired may also provide insight into the pathogenesis of HCC, which may be valuable for future HCC therapy.

Abstract
Transplantation is currently the best treatment for patients with end‑stage renal disease. However, acute rejection (AR) is the major source of failure in renal transplantation. The current best practice for the diagnosis of AR involves renal biopsy, but it is invasive, time‑consuming, costly and inconvenient. Sensitive and less invasive detection of AR episodes in renal transplant patients is essential to preserve allograft function. The present study applied isobaric tags for relative and absolute quantitation (iTRAQ) mass spectrometry to analyze serum protein expression in patients with AR and healthy controls. Overall, 1,399 proteins were identified. Using a cut‑off of Q<0.05 and a fold change of >1.2 for the variation in expression, 109 proteins were identified to be differentially expressed between the AR and control groups, 72 of which were upregulated and 37 were downregulated. Several proteins, including properdin, keratin 1, lipoprotein(a) and vitamin D‑binding protein, may have roles in the pathogenesis of AR. The present study focused on iTRAQ‑based proteomic profiling of serum samples in AR. Insight from the present study may help advance the understanding of the molecular mechanisms of AR and identify potential novel biomarkers of AR for further characterization.

Abstract
Background There are many situations of abnormal metabolism influencing liver graft function. This study aims to provide data for the development of liver function recovery after liver transplantation by dynamically analyzing metabolites of bile acids pathway in serum. Material/Methods A comprehensive metabolomics profiling of serum of 9 liver transplantation patients before transplantation, on the 1st, 3rd, and 7th days after liver transplantation, and healthy individuals were performed by ultra-performance liquid chromatography-mass spectrometry (UPLC-MS). Multivariate data and dynamic analysis were used to search for biomarkers between the metabolomics profiles present in perioperative liver transplantation and normal controls. Results Thirty-three differential endogenous metabolites were screened by the threshold of variable importance in the projection (VIP) from an orthogonal partial least square discriminant analysis (OPLS-DA) greater than 1.0, q-value <0.05, and fold change (FC) ≤0.8 or ≥1.2 between the preoperative group and the normal controls in negative mode. The metabolite intensities of taurocholic acid, taurochenodeoxycholic acid, chenodeoxycholic acid glycine conjugate, and glycocholic acid pre-transplantation were significantly higher than those of normal controls. The average metabolite intensities of taurocholic acid and taurochenodesoxycholic acid on the first day after liver transplantation were lower than those observed pre-transplantation. The average metabolite intensities on day 3 after liver transplantation showed a sudden increase and then decreased after 7 postoperative days. The average metabolite intensities of glycocholic acid and chenodeoxycholic acid glycine conjugate showed an increasing trend on the 1st, 3rd, and 7th days after liver transplantation. Conclusions Use of taurocholic acid and taurochenodeoxycholic acid-related bile secretion, liver regeneration, and de novo bile acid synthesis may help clinical evaluation and provide data for the development of liver function recovery after liver transplantation.

Abstract
Posttranslational modifications (PTMs) to histones such as lysine crotonylation are classified as epigenetic changes. Lysine crotonylation participates in various cellular processes and occurs in active promoters, directly accelerating transcription. The present study performed a proteomics analysis of crotonylation between healthy controls and patients with immunoglobulin A (IgA) nephropathy using tandem mass spectrometry and high-resolution liquid chromatography. The present results identified 353 crotonylated proteins and 770 modification sites, including 155 upregulated and 198 downregulated crotonylated proteins. In total, seven conserved motifs were identified in the present study. The present bioinformatics analysis results suggested a number of the crotonylated proteins exhibited various subcellular localization patterns, such as in the cytoplasm. Protein domains, including thioredoxin, moesin tail and myosin like IQ motif domains were markedly enriched in crotonylated proteins. Kyoto Encyclopedia of Genes and Genomes and functional enrichment analyses suggested significant enrichment of crotonylated proteins in complement and coagulation cascades, and antigen processing and presentation pathways displaying important relationships with IgA nephropathy. The present results suggested that crotonylation occurred in numerous proteins and may play key regulatory roles in IgA nephropathy.

Abstract
Background/Aims: End-stage renal disease (ESRD), characterized by progressive loss of rental function during the disease course, has been reported to be correlated with immune dysregulation. To date, a majority of previous studies on immune response to ESRD have been focused on the T-cell response. This prospective study was to assess the B-cell receptor (BCR) heavy chain repertoire in ESRD patients.Materials and methods: A total of 10 ESRD patients and six healthy controls were prospectively enrolled in this study. BCR immunoglobulin heavy chain (IGH) repertoire in the peripheral blood from ESRD patients and healthy individuals were analyzed by means of next generation sequencing (NGS) in combination with multiplex PCR, Illumina sequencing, and the international ImMunoGeneTics database (IMGT).Results: Abnormal BCR complementary-determining region 3 (CDR3) sequences were identified in relation to ESRD. We also found that the degree of the B-cell clonal expansion in the ESRD group was significantly greater than that in the control group (p < .05), whereas the distributions of BCR CDR3, V, D, J, and V-J gene segments were comparable between the ESRD and control groups. T-test for analysis of the distribution ratio of the V, D, J, and V-J genes revealed five up-regulated genes and nine down-regulated genes associated with ESRD, and there were significant differences between the ESRD and control groups (p < .05).Conclusions: We have provided a successful approach to analyzing peripheral B-cell repertoire in ESRD patients, and the results suggest a direct correlation between the BCR repertoire and ESRD. The ESRD-specific BCR CDR3 sequences may hold promise for potentially therapeutic benefit.

Abstract
Recent studies have shown that circular RNAs (circRNAs) exhibit differential expression in certain diseases. However, to the best of our knowledge, maternal fetal-derived circRNAs and mRNAs associated with Down's syndrome (DS) have not yet been investigated. A total of 12 umbilical cord blood samples were collected from pregnant women, including six women carrying fetuses with DS (diagnosed by G-banding karyotype analysis), and six women carrying fetuses without DS. In addition, 12 peripheral blood samples were obtained from children, including six children with DS and six children without DS. Gene chip technology was used to screen for differentially expressed circRNAs and mRNAs in the cord blood samples, and were subsequently verified by reverse transcription-quantitative polymerase chain reaction in peripheral blood from the children to identify potential biomarkers. Furthermore, circRNA/microRNA (miRNA) interactions were predicted using Arraystar miRNA target prediction software. There was a significant difference in the expression of hsa_circRNA_103127, hsa_circRNA_103112 and hsa_circRNA_104907 between cord blood obtained from the women carrying fetuses with and without DS, and between peripheral blood obtained from children with and without DS (P<0.01). As hsa_circRNA_103112 exhibited significant differences in expression between cord blood obtained from the women carrying fetuses with and without DS and between peripheral blood obtained from children with and without DS, its corresponding gene, ubiquitin specific peptidase 25, may be involved in the pathogenesis of the condition. These results suggested that hsa_circRNA_103112 may be upregulated in individuals with DS, resulting in an expression imbalance of diploid genes through interactions among circRNA, miRNA and mRNA. Therefore, the level of hsa_circRNA_103112 in the peripheral blood of a pregnant woman may serve as potential biomarker of fetal DS during non-invasive prenatal screening.

Abstract
Background Autosomal dominant osteopetrosis type II (ADO2) is a rare human genetic disease that has been broadly studied as an important osteopetrosis model; however, there are no disease-specific induced pluripotent stem cells (ADO2-iPSCs) that may be valuable for understanding the pathogenesis and may be a potential source of cells for autologous cell-based therapies. Methods To generate the first human ADO2-iPSCs from a Chinese family with ADO2 and to identify their characteristics, blood samples were collected from the proband and his parents and were used for genotyping by whole-exome sequencing (WES); the urine-derived cells of the proband were reprogrammed with episomal plasmids that contained transcription factors, such as KLF4, OCT4, c-MYC, and SOX2. The proteome-wide protein quantification and lysine 2-hydroxyisobutyrylation detection of the ADO2-iPSCs and normal control iPSCs (NC-iPSCs) were performed by high-resolution LC-MS/MS and bioinformatics analysis. Results WES with filtering strategies identified a mutation in CLCN7 (R286W) in the proband and his father, which was absent in the proband’s mother and the healthy controls; this was confirmed by Sanger sequencing. The ADO2-iPSCs were successfully generated, which carried a normal male karyotype (46, XY) and the mutation of CLCN7 (R286W); the ADO2-iPSCs positively expressed alkaline phosphatase and other surface markers; and no vector and transgene were detected. The ADO2-iPSCs could differentiate into all three germ cell layers, both in vitro and in vivo. The proteomic profiling revealed similar expression of pluripotency markers in the two cell lines and identified 7405 proteins and 3664 2-hydroxyisobutyrylated peptides in 1036 proteins in the ADO2-iPSCs. Conclusions Our data indicated that the mutation CLCN7 (R286W) may be a cause of the osteopetrosis family. The generated vector-free and transgene-free ADO2-iPSCs with known proteomic characteristics may be valuable for personalized and cell-based regenerative medicine in the future.

Abstract
The present study aimed to investigate the complexity and diversity of the T lymphocyte immune repertoire in patients with bladder cancer. To do so, the immune state of patients was assessed. The study also aimed to elucidate the aetiology and pathogenesis of bladder cancer to provide a novel theoretical basis for disease prevention, diagnosis, treatment and prognosis monitoring. Cancerous and paracancerous (control) tissue samples were collected from five patients diagnosed with muscle-invasive bladder cancer. Multiplex polymerase chain reaction and Illumina high-throughput sequencing were used to determine the characteristics and clonal diversity of the T-cell receptor (TCR) β-chain complementarity-determining region 3 (CDR3) gene in the cancerous and paracancerous tissues of patients with bladder cancer. The degree of clonal expansion in malignant samples was significantly higher than in adjacent samples. Furthermore, ΤCRβ variable (TRBV), ΤCRβ diversity (TRBD) and ΤCRβ joining (TRBJ) repertoires were significantly different in cancerous samples compared with adjacent samples. In addition, 13 identified V-J pairs were highly expressed in cancerous samples whereas they had low expression in control samples. In conclusion, the degree of T-cell clonal expansion in bladder cancerous tissue was higher than in paracancerous tissue, whereas the immune diversity of the tissues of patients with bladder cancer was significantly lower. The DNA sequence and amino acid sequences, and V-J combination level may be used to comprehensively understand the diversity and characteristics of TCR CDR3 in bladder cancer and paracancerous tissues, and to evaluate the immune status of bladder cancer to develop therapeutic targets and biomarkers for prognosis monitoring.

Abstract
The aim of the present study was to assess the genetic diversity of the B-cell receptor (BCR) in kidney transplant recipients with acute rejection. A total of three patients with acute rejection after kidney transplantation were examined by performing a composition and diversity analysis of the BCR immunoglobulin heavy chain (IGH) complementarity-determining region 3 (H-CDR3) repertoire. The peripheral blood mononuclear cells of patients were collected at 1 day prior to (Pre1), as well as 1 day (Post1) and 7 days (Post7) after the transplantation, and DNA was extracted. High-throughput sequencing technology was applied to determine the BCR repertoire. Raw sequences in FASTQ format were analyzed with the Basic Local Alignment Search Tool. The diversity of the BCR repertoire was assessed by calculating Shannon entropy, Simpson's diversity index, the Gini coefficient and highly expanded clone distributions. The diversity of the BCR repertoire at Pre1 was greater than that at Post1 or Post7. The diversity of the BCR repertoire was the lowest at Post1 and increased at Post7 but failed to reach the pre-transplantation levels. Patients exhibited the loss of seven IGH variable (IGHV)3 family genes, while five new genes were expressed at a low frequency. Furthermore, five IGHV-IGH joining (IGHJ) gene pairings, including IGHJ6-IGHV3-11, were detected in the patients. Up- and downregulated genes were assessed by calculating the expression frequencies of the IGH diversity and IGHV gene families at Post1 and Post7. The results of the H-CDR3 length distribution and H-CDR3 amino acid (AA) usage analyses indicated that in Case 1 and 2, the AA length was similar at mostly 14–18 AA, while that in Case 3 was relatively stable at 12–16 AA. In conclusion, the present results illustrate the diversity of H-CDR3 in patients with acute rejection after kidney transplantation may provide novel ideas, methods and means of monitoring and analyzing the immune status of patients under physiological and pathological conditions.

Abstract
Acute-on-chronic liver failure (ACLF) is a newly-defined serious syndrome with major features of acute decompensation (AD) of hepatic cirrhosis, liver failure and failure of multiple other organs. To date, the mechanism underlying the development and progression of ACLF remains to be fully elucidated. It has been noted that ACLF is associated with immune dysregulation. However, studies have mainly focused on T-cell responses. The present study aimed to determine the composition and alterations of B-cell receptor (BCR) heavy chain repertoires associated with ACLF using next generation sequencing (NGS). A total of six patients with hepatitis B virus (HBV)-related ACLF and six healthy control subjects were prospectively enrolled in the present study. The B-cell immunoglobulin heavy chain (IGH) repertoires in peripheral blood mononuclear cells (PBMCs) obtained from the patients with HBV-related ACLF and the control subjects were analyzed using NGS, coupled with multiplex polymerase chain reaction, were Illumina sequenced, and were further characterized using the international ImMunoGeneTics database. The distribution of the BCR complementarity-determining region 3 (CDR3) variable (V), diversity (D) and joining (J) and V-J gene segments were found to be comparable between the ACLF and control groups. Of note, the degree of clonal expansion in the ACLF group was significantly higher than that in the control group (P<0.05). Furthermore, a t-test of the distribution ratio of the V, D, J and V-J combinations in patients with ACLF and control subjects revealed differentially expressed genes. In total, six genes were upregulated and 19 genes were downregulated in response to ACLF. The difference between these two groups was statistically significant (P<0.05). The approach used in the present study was feasible and effective for analyzing peripheral B-cell repertoires in HBV-related ACLF. These results provide direct evidence that the BCR repertoire is important in immune responses, autoimmunity and alloreactivity, and that there is a link between the BCR repertoire and HBV-ACLF. Therefore, ACLF-specific BCR CDR3 sequences hold promise for therapeutic benefit to HBV-ACLF in the future.

Abstract
Liver cirrhosis of hepatitis B is an immune-related disease in which liver cells die during the body’s immune system activation to clear the virus, and the progress is closely related to T lymphocytes. T lymphocyte cells recognise antigens, specifically by major histocompatibility complex (MHC), through a membrane protein T cell receptor (TCR). Here, we used high throughput immune repertoire sequencing technique to study the characteristics and diversity of the TCR repertoire between patients who underwent liver transplantation and healthy controls (NC). We sequenced the TCR β-chain complementary-determining region 3 (CDR3) repertoire in peripheral blood mononuclear cells (PBMCs) from 6 liver transplantation patients before transplantation (Pre) and on the first (Post1) and seventh days (Post7) after transplantation along with 6 NC. We observed that the distributions of CDR3, VD indel, and DJ indel lengths were similar among the Pre, Post1, Post7 and NC groups. We found that the TCR repertoire diversity of transplantation groups was relatively lower compared to NC group. The Pre-group had more highly expanded T cell clones compared to Post1, Post7 and NC groups, and the diversity of the T cell repertoire of the Post7 group was significantly decreased compared to the Pre, Post1 and NC groups. In addition, we found our results also show that various TRBV expression increased and some public sequences at different time points after liver transplantation, and the expression levels of 3 TRBV segments and 2 TRBJ segments were also significantly different in Pre, Post1, Post7 and NC groups. Moreover, 1 aa sequence shared by all liver transplantation patients and 2 aa sequences shared by at least two groups, which may serve as biomarkers to monitor the immune status of liver transplant patients.

Abstract
INTRODUCTION Histone post-translational modifications (PTMs) carry epigenetic information to regulate diverse cellular processes at the chromatin level. Crotonylation, one of the most important and common PTMs, plays a key role in the regulation of various biological processes. However, no study has evaluated the role of lysine crotonylation in maintenance hemodialysis patients (MHP). METHODS Here, we comparatively evaluated the crotonylation proteome of normal controls (NC) and MHP using liquid chromatography tandem mass spectrometry (LC-MS/MS) coupled with highly sensitive immune-affinity purification. RESULTS A total of 1109 lysine modification sites distributed on 347 proteins were identified, including 93 and 252 crotonylated upregulated and downregulated proteins, respectively. Thus, a decrease in crotonylation of histone proteins was observed in patients with kidney failure undergoing maintenance hemodialysis. Intensive bioinformatic analysis revealed that most of the crotonylated proteins were distributed in the cytoplasm, nucleus, mitochondria, and extracellular region. Gene ontology enrichment analysis showed that the crotonylated proteins were significantly enriched in the platelet alpha granule lumen, platelet degranulation, and cell adhesion molecule binding. In addition, protein domain, including fibrinogen alpha/beta/gamma chain, zinc finger, and WD40-repeat-containing domain, were significantly enriched in crotonylated proteins. Kyoto Encyclopedia of Genes and Genomes (KEGG)-based functional enrichment analysis revealed that crotonylated proteins were enriched in complement and coagulation cascades, cardiac muscle contraction, and hematopoietic cell lineage, all of which have important associations with hemodialysis complications. CONCLUSIONS This is the first report on the global crotonylation proteome of MHP. Lysine crotonylation was found to play important regulatory roles in pathophysiological processes in MHP.

Abstract
Recent studies have shown that circular ribonucleic acids have differential expression in some diseases. This study compared the expression levels of five circular ribonucleic acids between patients of primary hepatic carcinoma following liver transplantation and healthy individuals for searching a new diagnostic biomarker about primary hepatic carcinoma. We chose differentially expressed targeted circular ribonucleic acids according to fold change ≥2.0 or ≤-2.0 between circular ribonucleic acids microarray of perioperative liver transplantation and normal controls. Then we used the Arraystar home-made micro-ribonucleic acid target prediction software based on TargetScan and miRanda to predict circular ribonucleic acid/micro-ribonucleic acid interactions. And we assess the expression levels of hsa_circ_100571, hsa_circ_400031, hsa_circ_102032, hsa_circ_103096, and hsa_circ_102347 in the peripheral blood of normal controls and liver transplantation patients before transplantation and on the first, third, and seventh days after transplantation by real-time quantitative polymerase chain reaction. We chose five circular ribonucleic acids, two of which have been correlated with micro-ribonucleic acid-related carcinoma recurrence after liver transplantation, hepatocellular carcinoma and analyzed their expression with 2-△△Ct method. The expression level of hsa_circ_100571 and hsa_circ_400031 on day 1 after liver transplantation was higher than pre-transplantation (p < 0.01), and these levels showed a declining trend on post-transplantation. The expression level of hsa_circ_102032 and hsa_circ_103096 on day 1 after liver transplantation was lower than pre-transplantation (p < 0.01) and decreased on post-transplantation. There were the significantly different expressions between the post-transplantation day 7 and normal control (p < 0.01). The expression level of hsa_circ_102347 on day 1 after liver transplantation was lower than pre-transplantation (p < 0.01). This expression showed a declining trend on post-transplantation, and the postoperative day 7 level was similar to normal control (p > 0.05). Five types of circular ribonucleic acid-related micro-ribonucleic acids had varying degrees of upregulation and downregulation between perioperative transplantation of primary hepatic carcinoma patients and normal controls; the hsa_circ_102347 is most likely to have association with primary hepatic carcinoma.

Abstract
Background Diabetic nephropathy (DN) is a severe complication of diabetes mellitus (DM). Pancreas or islet transplantation has been reported to prevent the development of DN lesions and ameliorate or reverse existing glomerular lesions in animal models. Shortage of pancreas donor is a severe problem. Islets derived from stem cells may offer a potential solution to this problem. Objective To evaluate the effect of stem cell-derived islet transplantation on DN in a rat model of streptozotocin-induced DM. Methods Pancreatic progenitor cells were isolated from aborted fetuses of 8 weeks of gestation. And islets were prepared by suspension culture after a differentiation of progenitor cells in medium containing glucagon-like peptide-1 (Glp-1) and nicotinamide. Then islets were transplanted into the liver of diabetic rats via portal vein. Blood glucose, urinary volume, 24 h urinary protein and urinary albumin were measured once biweekly for 16 weeks. Graft survival was evaluated by monitoring human C-peptide level in rat sera and by immunohistochemical staining for human mitochondrial antigen and human C-peptide in liver tissue. The effect of progenitor-derived islets on filtration membrane was examined by electron microscopy and real-time polymerase chain reaction (PCR). Immunohistochemical staining, real-time PCR and western blot were employed for detecting fibronectin, protein kinase C beta (PKCβ), protein kinase A (PKA), inducible nitric oxide synthase (iNOS) and superoxide dismutase (SOD). Results Islet-like clusters derived from 8th gestational-week human fetal pancreatic progenitors survived in rat liver. And elevated serum level of human C-peptide was detected. Blood glucose, 24 h urinary protein and urinary albumin were lower in progenitor cell group than those in DN or insulin treatment group. Glomerular basement membrane thickness and fibronectin accumulation decreased significantly while podocytes improved morphologically in progenitor cell group. Furthermore, receptor of advanced glycation end products and PKCβ became down-regulated whereas PKA up-regulated by progenitor cell-derived islets. And iNOS rose while SOD declined. Conclusions DN may be reversed by transplantation of human fetal pancreatic progenitor cell-derived islets. And fetal pancreatic progenitor cells offer potential resources for cell replacement therapy.

Abstract
Chronic antibody-mediated rejection (ABMR) is a major cause of the transplant renal interstitial fibrosis and transplanted kidney epithelial cell transdifferentiation is one of the main mechanisms. The transforming growth factor (TGF)-β1/integrin-linked kinase (ILK) signaling pathway has a significant role in the epithelial-mesenchymal transition (EMT) of renal tubular epithelial cells; however, the molecular mechanisms of this process have remained elusive. The present study confirmed that Akt and glycogen synthase kinase (GSK)-3β, as TGF-β1 downstream signaling factors, are involved in fibrotic processes caused by kidney disease, which, however, has been rarely reported in the kidney transplant field. Based on the Banff 2009 standard, transplanted kidney specimens were classified according to the fibrosis level. The results showed that with the reduction of the interstitial fibrosis level, E-cadherin expression was gradually reduced, while α-smooth muscle actin expression progressively increased. The expression of Akt and GSK-3β in normal human kidney tissue was not obvious but showed a marked increase with the aggravation of the interstitial fibrosis level, which confirmed the occurrence of EMT during the fibrosis process, and that phosphorylated (p)-Akt and GSK-3β have an important role in the EMT process in the transplanted kidney. A correlation analysis of p-Akt, GSK-3β, TGF-β1 and ILK suggested that overexpression of p-Akt and GSK-3β may induce and mediate the transdifferentiation of renal tubular epithelial cells to myofibroblasts and that this proceeds via TGFβ1/ILK signaling pathways.

Abstract
Thrombophilia is a multifactorial disorder involving environmental and genetic factors. Well‑known factors that result in predisposition to congenital disorders associated with thrombophilia include antithrombin deficiency, protein C and S deficiency, Factor V Leiden mutation, abnormal prothrombin and antiphospholipid syndrome. The present study revealed an association between a mutation of the F2 gene, which codes for coagulation factor II, thrombin, and the risk of thrombophilia in a Han Chinese family, of which four members (I‑2, II‑2, II‑3 and III‑1) had a history of deep venous thromboembolism. The disease was measured in this family using laboratory measurements and computed tomography angiography. To identify the abnormality underlying the increased thrombophilia risk, whole‑exome sequencing technology was used to analyze two affected individuals (II‑2 and III‑1). An exonic missense F2 mutation, T165M (NM_000506:c.C494T:p.T165M;rs5896), was identified from a total of 2,222 and 2,203 genetic variations observed in the two affected individuals, respectively, which were subsequently filtered and confirmed using Sanger sequencing. I‑2, II‑3 and III‑1 shared this mutation with the proband (II‑2), and II‑6 had a heterozygous form of the mutation. This deleterious mutation was not identified in normal controls. The present study may improve understanding of the function of the F2 gene.

Abstract
With the advent of next-generation sequencing technology, the cost of sequencing has significantly decreased. However, sequencing costs remain high for large-scale studies. In the present study, DNA pooling was applied as a cost-effective strategy for sequencing. The sequencing results for 100 healthy individuals obtained via whole-genome resequencing and using DNA pooling are presented in the present study. In order to minimise the likelihood of systematic bias in sampling, paired-end libraries with an insert size of 500 bp were prepared for all samples and then subjected to whole-genome sequencing using four lanes for each library and resulting in at least a 30-fold haploid coverage for each sample. The NCBI human genome build37 (hg19) was used as a reference genome for the present study and the short reads were aligned to the reference genome achieving 99.84% coverage. In addition, the average sequencing depth was 32.76. In total, ~3 million single-nucleotide polymorphisms were identified, of which 99.88% were in the NCBI dbSNP database. Furthermore, ~600,000 small insertion/deletions, 500,000 structure variants, 5,000 copy number variations and 13,000 single nucleotide variants were identified. According to the present study, the whole genome has been sequenced for a small sample subjects from southern China for the first time. Furthermore, new variation sites were identified by comparing with the reference sequence, and new knowledge of the human genome variation was added to the human genomic databases. Furthermore, the particular distribution regions of variation were illustrated by analyzing various sites of variation, such as single-nucleotide polymorphisms.

Abstract
Down syndrome (DS) is caused by trisomy of human chromosome 21 and is associated with a number of deleterious phenotypes. To investigate the role of microRNA (miRNA) in the regulation of DS, high‑throughput Illumina sequencing technology and isobaric tagging for relative and absolute protein quantification analysis were utilized for simultaneous expression profiling of miRNA and protein in fetuses with DS and normal fetuses. A total of 344 miRNAs were associated with DS. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway analyses were used to investigate the proteins found to be differentially expressed. Functionally important miRNAs were determined by identifying enriched or depleted targets in the transcript and the protein expression levels were consistent with miRNA regulation. The results indicated that GRB2, TMSB10, RUVBL2, the hsa‑miR‑329 and hsa‑miR‑27b, hsa‑miR‑27a targets, and MAPK1, PTPN11, ACTA2 and PTK2 or other differentially expressed proteins were connected with each other directly or indirectly. Integrative analysis of miRNAs and proteins provided an expansive view of the molecular signaling pathways in DS.

Abstract
Hepatitis B virus (HBV) DNA polymerase transactivated protein 1 (HBVDNAPTP1) is a novel protein upregulated by HBV DNA polymerase, which has been screened by suppression subtractive hybridization technique (SSH) (GenBank Acc. No. AY450389). A vector pcDNA3.1 (-)/myc-His A-HBVDNAPTP1 was constructed and used to transfect acute monocytic leukemia cell line THP-1. HBVDNAPTP1 expression was detected by Western blot analysis in the cells. A cDNA library of genes downregulated by HBVDNAPTP1 in THP-1 cells was made in pGEM-T Easy using SSH. The cDNAs were sequenced and analyzed with BLAST search against the sequences in GenBank. Some sequences, such as DNA repair protein SWI5 homolog (SWI5) and CTS telomere maintenance complex component 1 (CTC1), might be involved in DNA repair. Protein expression of SWI5 and CTC1 was identified by Western blot in THP-1 cells. HBVDNAPTP1 could downregulate the expression of SWI5 and CTC1 at translation level.

Abstract
Delayed T cell recovery and restricted T cell receptor (TCR) diversity after kidney transplantation are associated with increased risks of infection and malignancy. Technical challenges limit the faithful measurement of TCR diversity after kidney transplantation. In this study, we used a combination of multiplex-PCR, Illumina sequencing and IMGT/HighV-QUEST to directly assess millions of TCRs per individual before and at two time points after kidney transplantation (1days and 7days after transplantation) in a cohort of 10 patients compared to a normal control (NC) group (n=10). We identified the most commonly observed CDR3 length, VD indel length, and DJ indel length in transplantation group and normal group. In addition, we found that the TCR repertoire diversity of transplantation groups was relatively lower compared to NC group. T cell depletion in Post-1 group can be observed, which resulted in the altered distribution characteristics of clonotype abundance. A modest proportion of high abundance clones were shared among the pre-1 group, post-1 group and post-7 group, and it did not exist in the NC group, which exhibited a signature of antigen selection. Moreover, our results also demonstrated that various TRBV expression increased and some public sequences at different time points after kidney transplantation, which may provide biomarkers to monitor the immune status of transplant patients.

Abstract
There is increasing evidence that several genes are associated with an increased risk of type 2 diabetes (T2D); genome-wide association investigations and whole-genome re-sequencing investigations offer a useful approach for the identification of genes involved in common human diseases. To further investigate which polymorphisms confer susceptibility to T2D, the present study screened for high-contribution susceptibility gene variants Chinese patients with T2D using whole-genome re-sequencing with DNA pooling. In total, 100 Chinese individuals with T2D and 100 healthy Chinese individuals were analyzed using whole-genome re-sequencing using DNA pooling. To minimize the likelihood of systematic bias in sampling, paired-end libraries with an insert size of 500 bp were prepared for in T2D in all samples, which were then subjected to whole-genome sequencing. Each library contained four lanes. The average sequencing depth was 35.70. In the present study, 1.36 GB of clean sequence data were generated, and the resulting calculated T2D genome consensus sequence covered 99.88% of the hg19 sequence. A total of 3,974,307 single nucleotide polymorphisms were identified, of which 99.88% were in the dbSNP database. The present study also found 642,189 insertions and deletions, 5,590 structure variants (SVs), 4,713 copy number variants (CNVs) and 13,049 single nucleotide variants. A total of 1,884 somatic CNVs and 74 somatic SVs were significantly different between the cases and controls. Therefore, the present study provided validation of whole-genome re-sequencing using the DNA pooling approach. It also generated a whole-genome re-sequencing genotype database for future investigations of T2D.

Abstract
OBJECTIVE Mental retardation is characterized by lower intelligence compared to the average intelligence of persons the same age. These patients have low adaptive capacity acquired by society. The genetic factors of causing MR include monogenic disease, chromosome structural aberration, and chromosome number aberration and so on. We explored the cause of a Chinese family suffering from mental retardation. METHODS We used karyotyping technology to determine the karyotype of the proband, and we used FISH to verify the result of the karyotyping. We used whole-exome sequencing to identify the disease-causing gene and used Sanger sequencing to verify the result of whole-exome sequencing to assess the family's gene expression. RESULTS The G-banding of the karyotype revealed that the patient's karyotype is 46, XY. FISH revealed that the patient does not have a trisomy syndrome. The karyotype of the proband is normal. Using whole-exome sequencing, we identified 108,767 variants in the exome gene of the patient, including 101,787 SNPs and 6980 InDels. Combining clinical information and bioinformatics analysis, including databases filtering and SIFT analysis, we found ARHGAP4 in X chromosome was candidate MR disease-causing gene. PCR and Sanger sequencing results were consistent with whole-exome sequencing. ARHGAP4 (T491M) mutation was present in the genome of the proband and his mother is a carrier, while his father, sister, and brother do not carry this mutation. CONCLUSION According to clinical information, whole-exome sequencing results and Sanger verification results, ARHGAP4 (T491M) mutation may be disease-causing gene of the MR patient. The relation between ARHGAP4 mutation and MR clinical characteristic is needed to be illuminated with participation of more MR patients.

Abstract
Systemic lupus erythematosus (SLE) is a multifactorial autoimmune disease which affects different organs and systems that, has a complex genetic inheritance, and is affected by both epigenetic and environmental risk factors. Previous studies on SLE have lacked the statistical power and genetic resolution to fully determine the influence of major histocompatibility complex (MHC) on SLE. In this study, in order to determine this influence, a total of 15 patients with SLE and 15 healthy controls were enrolled. MHC region capture technology, hMeDIP-chip, transcribed ultra-conserved region (T-UCR) microarray and bioinformatics analysis were utilized for both groups. The results revealed methylated CpG enrichment at 6 loci in the MHC segment of SLE. We found 4 single-nucleotide polymorphisms (SNPs) in the CpG promoter of human leukocyte antigen-B (HLA-B) and 2 SNPs in chr6:29521110‑29521833. No significant GO term or KEGG pathway enrichment was noted for an immune-correlated process in the SLE patients for the corresponding CpG-methylated genes. In this study, T-UCR was not discovered in the MHC segment. The analysis of SNPs (rs1050683, rs12697943, rs17881210, rs1065378, rs17184255 and rs16895070) and gene expression in peripheral blood lymphocytes indicated that these SNPs were associated with the occurrence of SLE. Further studies are warranted to examine the roles of these SNPs in the pathogenesis of SLE. Integrative analysis technology provided a view of the molecular signaling pathways in SLE.

Abstract
OBJECTIVE The objective of this study was to measure the 3'-untranslated region (3'-UTR) polymorphism lengths in peripheral blood mononuclear cells (PBMCs) from uremia patients. METHOD We sequenced the alternative polyadenylation sites in the 3'-UTR of PBMCs from 10 uremic patients and 10 healthy people to detect different gene expression levels between uremia patients and healthy controls. Quantitative reverse transcription polymerase chain reaction was used as validation. RESULT Compared with the healthy control group, 691 genes in uremic patients had significantly different 3'-UTR lengths. Of these genes, 475 genes showed shortened 3'-UTRs, and the 3'-UTRs of 216 genes were lengthened. The verification results matched the original sequencing results. CONCLUSION There were significant differences in 3'-UTR lengths between uremic patients and healthy controls, and analysis of the differential genes may contribute to the understanding of uremia pathogenesis.

Abstract
Systemic lupus erythematosus (SLE) is a chronic, potentially fatal systemic autoimmune disease characterized by the production of autoantibodies against a wide range of self-antigens. To investigate the role of the 5-hmC DNA modification with regard to the onset of SLE, we compared the levels 5-hmC between SLE patients and normal controls. Whole blood was obtained from patients, and genomic DNA was extracted. Using the hMeDIP-chip analysis and validation by quantitative RT-PCR (RT-qPCR), we identified the differentially hydroxymethylated regions that are associated with SLE. There were 1,701 genes with significantly different 5-hmC levels at the promoter region in the SLE patients compared with the normal controls. The CpG islands of 3,826 genes showed significantly different 5-hmC levels in the SLE patients compared with the normal controls. Out of the differentially hydroxymethylated genes, three were selected for validation, including TREX1, CDKN1A and CDKN1B. The hydroxymethylation levels of the three genes were confirmed by RT-qPCR. The results suggested that there were significant alterations of 5-hmC in SLE patients. Thus, these differentially hydroxymethylated genes may contribute to the pathogenesis of SLE. These findings show the significance of 5-hmC as a potential biomarker or promising target for epigenetic-based SLE therapies.

Abstract
There are increasing numbers of patients on liver transplant waiting lists, and there is a continuing organ shortage crisis. Therefore, more centers and organ procurement organizations are developing protocols for donation after cardiac death. However, the effect of donation after cardiac death allografts on overall patient survival remains controversial, with some centers reporting equivalent patient posttransplant survival but many others indicating increased rates of complications, retransplant, use of resources, and death. Several potential risk factors that predict graft loss and recipient complications have been identified. To improve patient outcomes and reduce dropouts, experimental strategies that target both donors and recipients at various phases of the transplant process have focused on attenuating ischemia-reperfusion injury and have achieved encouraging results. In the present article, our goal is to provide an overview of the current status of, and recent advances in, liver transplant from donation after cardiac death, to better understand the risks and potential benefits of donation after cardiac death liver transplant.

Abstract
Membranous nephropathy (MN) is a common cause of nephrotic syndrome in adults and the second leading cause of end-stage renal disease due to primary glomerulonephritis. The aim of the present study was to identify potential biomarkers of MN and further characterize these proteins by Gene Ontology (GO) analysis. Isobaric tags for relative and absolute quantification were used to compare the protein levels in tissues from MN patients and healthy individuals, and the combined samples were subsequently separated by specialized communications exchange. Mass spectrometry data acquisition was conducted using a 4800 Plus MALDI TOF/TOF tandem mass spectrometry device, and the results were subjected to statistical analysis. A total of 1,903 proteins were identified, with 423 proteins exhibiting a difference of >1.5-fold compared with the control group. Of these, 202 proteins were upregulated, while 221 proteins were downregulated. In conclusion, GO enrichment analysis revealed that the differentially expressed proteins were primarily mapped to the following GO terms: ‘Immune response’, ‘immune effector process’, ‘activation of immune response’ and ‘positive regulation of immune system process’. The affected proteins may be associated with the pathogenesis of MN; thus, may represent candidate MN biomarkers.

Abstract
Development of effective immunosuppressive agents and advances in surgical practice are the main reasons for the success of transplantation in China. In some key areas such as liver, lung, and kidney transplants, Chinese transplant success rates are similar to the rates in developed countries. Organ donation also has developed rapidly. However, China is facing a serious organ shortage that restricts clinical treatment and medical research. This shortage is due to imperfect laws and improper management of organ donation, as well as Chinese traditional ethics. Finding an efficient way to make the number of donated organs keep pace with the need for organ transplants and to optimize allocation of organ resources is a long-term and arduous task. In some ways, Chinese organ donation nowadays is constrained more by legal issues than by medical issues. The current status of and challenges facing organ donation in China are analyzed with respect to ethics, management, laws, and policy, and the future development of transplantation in China is discussed.

Abstract
Immunoglobulin A nephropathy (IgAN) is a complex trait regulated by the interaction among multiple physiologic regulatory systems and probably involving numerous genes, which leads to inconsistent findings in genetic studies. One possibility of failure to replicate some single-locus results is that the underlying genetics of IgAN nephropathy is based on multiple genes with minor effects. To learn the association between 23 single nucleotide polymorphisms (SNPs) in 14 genes predisposing to chronic glomerular diseases and IgAN in Han males, the 23 SNPs genotypes of 21 Han males were detected and analyzed with a BaiO gene chip, and their associations were analyzed with univariate analysis and multiple linear regression analysis. Analysis showed that CTLA4 rs231726 and CR2 rs1048971 revealed a significant association with IgAN. These findings support the multi-gene nature of the etiology of IgAN and propose a potential gene-gene interactive model for future studies.

Abstract
INTRODUCTION Recent studies have shown that serum microRNAs have specific expression patterns in some diseases, indicating the potential of using microRNAs to aid diagnosis. This study estimated the levels of microRNAs in patients with nephrotic syndrome compared with healthy controls. MATERIALS AND METHODS In this study, real-time quantitative polymerase chain reaction was used to explore whether there were different expression levels of miR-181a, miR-483-5p, and miR-557 in the serum of patients with nephrotic syndrome subtypes and healthy controls. We measured the three microRNAs in 40 patients with nephrotic syndrome and 16 healthy controls. RESULTS The circulating levels of miR-483-5p and miR-557 were not significantly upregulated or downregulated, whereas miR-181a was significantly upregulated in patients with nephrotic syndrome as compared with healthy controls. CONCLUSIONS We found that circulating miR-181a had a significantly different expression and could be an effective means to aid diagnosis of nephrotic syndrome. This microRNA is an attractive candidate as a biomarker for nephrotic syndrome.

Abstract
Immunoglobulin (Ig) A nephropathy (IgAN) is the most common form of glomerulonephritis. In clinical practice, it is difficult to monitor the repeating relapse in patients suffering from IgAN, which usually occurs within 10 years of end-stage renal disease. In order to identify and quantify the total protein content in the renal tissue of patients with IgAN, isobaric tags for relative and absolute quantification (iTRAQ) technology was performed. iTRAQ coupled with multiple chromatographic fractionation and tandem mass spectrometry was used to analyze the total protein of normal renal tissue in IgAN and healthy patients. The individual proteins were identified by the Mascot search engine and any that were differentially expressed were monitored. A total of 574 different proteins were identified, and 287 proteins were up- or downregulated by >1 fold alteration in levels. The results showed that iTRAQ-based quantitative proteomic technology for the identification and relative quantitation of the renal tissue proteome is efficiently applicable. The differential expression of the proteome profiles for IgAN patients was determined. Further studies using large cohorts of patient samples with long-term clinical follow-up data should be conducted to evaluate the usefulness of the pathogenesis and novel biomarker candidates of IgAN, which may develop a novel technique for the diagnosis of IgAN.

Abstract
The global features of trimethylations of histone 3 at lysine 9 (H3K9me3) have been well studied in recent years; however, most of these studies were performed in mammalian cell lines. In this study, we generated genome-wide maps of H3K9me3 of the human heart and spleen using chromatin immunoprecipitation followed by high-throughput sequencing (ChIP-seq) technology. We examined the global patterns of H3K9me3 in both tissues and found that modifications were closely associated with tissue-specific expression, function, and development. In addition, we found that 169 genes displayed significant H3K9me3 differences between the heart and spleen. Among these genes, 64 were heart-H3K9me3-specific, 87 genes were spleen-H3K9me3-specific, and 18 were shared in both heart- and spleen-H3K9me3. In conclusion, we observed significant differences in H3K9me3 in the heart and spleen, which may help to explain epigenetic differences between these tissues. Such novel findings highlight the significance of H3K9me3 as a potential biomarker or promising target for epigenetic-based disease treatment.

Abstract
OBJECTIVE To explore the relationship between the major allergens of 6 common allergic foods and IgA nephropathy. METHODS A sensitive sandwich enzyme-linked immunosorbent assay (ELISA) was used to detect the serum levels of food-specific IgA1, IgG and IgE in 31 patients with IgA nephropathy and 80 healthy volunteers. All the patients were examined for a history of food allergy using a questionnaire. RESULTS Serum levels of IgA1 and IgG against the major allergens of the 6 common allergic foods were significantly higher in patients with IgA nephropathy than in healthy volunteers (P<0.05). There was no detectable food-specific IgE antibodies in the two groups. No patients had a clear history of food allergy. All the patients with increased IgG levels specific to 4 or more foods simultaneously had proteinuria. CONCLUSIONS Some foods especially the highly allergic ones may participate in the pathogenesis and progression of IgA nephropathy.

Abstract
Systemic lupus erythematosus (SLE) is a complex autoimmune disease, and correct judgment of SLE activity is very important in guiding precise clinical treatment. Circulating microRNAs (miRNAs) could serve as potential biomarkers of disease activity or status in SLE, and here we describe a modified qRT-PCR method for detecting them. Stem loop has become one of the most powerful methods for determining miRNA expression because it is highly sensitive and accurate and requires only small amount of sample. In this chapter, we focus on a stem-loop reverse transcription-bound SYBR green qRT-PCR protocol for evaluating a particular circulating miRNA species in SLE patients.

Abstract
Systemic lupus erythematosus (SLE) is a complex autoimmune disease, which predominantly occurs in females and is characterized by autoantibody production against a host of nuclear self-antigens and deposition of proinflammatory immune complexes in the organs including kidney glomeruli. MicroRNAs are small noncoding intracellular RNAs that modulate gene expression at the posttranslational level. Microarray technology is in widespread use for analysis of microRNA (miRNA) gene expression because of its flexibility and accurate high throughput. RNA microarray technology is based on nucleic acid hybridization between a mixture of labeled RNA targets and their corresponding complementary probes. This article offers a technological overview of microarray technology for analysis of microRNA gene expression in kidney biopsies from SLE patients.
