Abstract
BACKGROUND Atherosclerosis is a chronic cardiovascular disease of great concern. However, it is difficult to establish a direct connection between conventional small animal models and clinical practice. The pig's genome, physiology, and anatomy reflect human biology better than other laboratory animals, which is crucial for studying the pathogenesis of atherosclerosis. METHODS We used whole-genome sequencing data from nine Bama minipigs to perform a genome-wide linkage analysis, and further used bioinformatic tools to filter and identify underlying candidate genes. Candidate gene function prediction was performed using the online prediction tool STRING 12.0. Immunohistochemistry and immunofluorescence were used to detect the expression of proteins encoded by candidate genes. RESULTS We mapped differential single nucleotide polymorphisms (SNPs) to genes and obtained a total of 102 differential genes, then we used GO and KEGG pathway enrichment analysis to identify four candidate genes, including SLA-1, SLA-2, SLA-3, and TAP2. nsSNPs cause changes in the primary and tertiary structures of SLA-I and TAP2 proteins, the primary structures of these two proteins have undergone amino acid changes, and the tertiary structures also show slight changes. In addition, immunohistochemistry and immunofluorescence results showed that the expression changes of TAP2 protein in coronary arteries showed a trend of increasing from the middle layer to the inner layer. CONCLUSIONS We have identified SLA-I and TAP2 as potential susceptibility genes of atherosclerosis, highlighting the importance of antigen processing and immune response in atherogenesis.

Abstract
Urothelial cell carcinoma is one of the costliest types of cancer because of its recurrence, lengthy course of therapy, and tendency to lead to further complications. Gene polymorphisms are one of many factors that are thought to cause the carcinogenesis of urothelial cell carcinoma. Two single-nucleotide polymorphisms (SNPs) of the transporter associated with antigen processing (TAP) 1 gene and their relationship with the risks of urothelial cell carcinoma in the Japanese population were examined in this study by using polymerase chain reaction (PCR), restriction fragment length polymorphism (RFLP) for genotyping and statistical analysis. The adjusted odd ratios with 95% confidence interval (CI) of the mutant types (A/G+G/G) in females for the I333V and D637G polymorphisms are 2.28 (1.11-4.66) and 2.50 (1.21-5.17), respectively. The findings showed that females with the (A/G+G/G) genotype are more likely to develop urothelial cell carcinoma than those with the A/A genotype. Any correlation between smoking and gene polymorphism was absent. Results indicate that TAP1 gene polymorphisms and the risk of urothelial cell carcinoma are related in females.

The antigen processing-associated transporter gene polymorphism: Role on gene and protein expression in HPV-infected pre-cancerous cervical lesion. Front Cell Infect Microbiol 2022; 12:979800.

Abstract
Human papillomavirus (HPV) is the major pathogen for cervical lesions. The evasion mechanism of the immune response and persistence of HPV infection can be influenced by polymorphisms (SNPs) in genes associated with transporter associated with antigen processing (TAP), which may change the peptide binding affinity or the TAP expression impacting the efficiency of peptide transport in the secretory pathway, and the presentation of peptides to cytotoxic T lymphocytes. This study aimed to evaluate the role of the TAP1 and TAP2 polymorphisms, TAP1, and TAP2 genes expressions, and protein levels in cervical cells presenting different degrees of pre-cancerous lesions in 296 immunocompetent women infected or not by HPV. TAP SNPs were genotyped by Sanger sequencing, and gene expression by real-time PCR. Aneuploidy was determined by DNA index using flow cytometry. TAP-1 and TAP-2 tissue expressions were evaluated by immunohistochemistry. The Asp697Gly SNP of TAP1 presented a risk for cellular aneuploidy (P=0.0244). HPV+ women had higher TAP-2 mRNA (P=0.0212) and protein (P<0.0001) levels. The TAP2D and TAP2E haplotypes were associated with the risk for aneuploidy and pre-cancerous lesions. In conclusion, nucleotide variability at the peptide binding region of peptide transporter genes, particularly of the TAP2 gene, may influence the HPV-peptide transportation from the cytosol to the endoplasmic reticulum, increasing the susceptibility to the development of high-grade cervical lesions.

Association between TAP gene polymorphisms and tuberculosis susceptibility in a Han Chinese population in Guangdong. Mol Genet Genomics 2022; 297:779-790.

Abstract
Tuberculosis (TB) is an important public health problem. Studies indicated that TAP plays a key role in the presentation and transport of antigenic peptides during anti-M.tb infection. Given the important biological role of the TAP gene involved in anti-M.tb infection, a family-based case–control study including 133 tuberculosis patients, 107 healthy household contacts, and 173 healthy controls was conducted to assess the association between TAP gene polymorphisms and TB susceptibility. The basic information of subjects and their blood samples were collected. Four SNPs including rs1135216, rs1057141, rs241447, and rs3819721 were genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR–RFLP). Our results suggested that BMI, residence, bedroom crowding, indoor humidity, fitness activities, history of smoking, and TB exposure history were associated with the occurrence of tuberculosis (P < 0.05). A significant association was observed between the TAP1 rs1135216 CT/CC genotype and increased TB risk, and the ORs were 2.56 (95% CI 1.31–4.99) and 6.73 (95% CI 1.33–34.02), respectively. TAP2 rs3819721 GG genotype carriers also showed an increased risk of TB when compared TB patients to healthy household contacts. Haplotype analysis revealed that the haplotype CT at rs1057141 and rs1135216 (OR = 11.34, 95% CI 1.49–86.56; OR = 7.45, 95% CI 1.43–38.76), as well as TA at rs241447 and rs3819721 (OR = 2.20, 95% CI 1.07–4.56) had a significantly increased risk of TB. The genetic risk scores (GRS) analysis of the four loci indicated that the risk of tuberculosis increased with increasing GRS scores in TB vs HHC (Ptrend = 0.010) and in TB vs HC (Ptrend = 0.001). In conclusion, our findings suggested that the SNPs of rs1135216 and rs3819721 were associated with TB susceptibility among the tuberculosis-prone families in the Chinese Han population and the risk of developing tuberculosis increases with the number of risk alleles, which could help identify high-risk groups in time and take scientific preventive measures. Further cohort studies with large samples are needed to validate the role of TAP gene variants on TB susceptibility.

Structural determinants of peptide-dependent TAP1-TAP2 transit passage targeted by viral proteins and altered by cancer-associated mutations. Comput Struct Biotechnol J 2021; 19:5072-5091. [PMID: 34589184 PMCID: PMC8453138 DOI: 10.1016/j.csbj.2021.09.006] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2021] [Revised: 09/06/2021] [Accepted: 09/06/2021] [Indexed: 01/20/2023] Open
Abstract
The TAP1-TAP2 complex transports antigenic peptide substrates into the endoplasmic reticulum (ER). In ER, the peptides are further processed and loaded on the major histocompatibility class (MHC) I molecules by the peptide loading complex (PLC). The TAP transporters are linked with the PLC; a target for cancers and viral immune evasion. But the mechanisms whereby the cancer-derived mutations in TAP1-TAP2 or viral factors targeting the PLC, interfere peptide transport are only emerging. This study describes that transit of peptides through TAP can take place via two different channels (4 or 8 helices) depending on peptide length and sequence. Molecular dynamics and binding affinity predictions of peptide-transporters demonstrated that smaller peptides (8-10 mers; e.g. AAGIGILTV, SIINFEKL) can transport quickly through the transport tunnel compared to longer peptides (15-mer; e.g. ENPVVHFFKNIVTPR). In line with a regulated and selective peptide transport by TAPs, the immunopeptidome upon IFN-γ treatment in melanoma cells induced the shorter length (9-mer) peptide presentation over MHC-I that exhibit a relatively weak binding affinity with TAP. A conserved distance between N and C terminus residues of the studied peptides in the transport tunnel were reported. Furthermore, by adversely interacting with the TAP transport passage or affecting TAPNBD domains tilt movement, the viral proteins and cancer-derived mutations in TAP1-TAP2 may induce allosteric effects in TAP that block conformation of the tunnel (closed towards ER lumen). Interestingly, some cancer-associated mutations (e.g. TAP1R372Q and TAP2R373H) can specifically interfere with selective transport channels (i.e. for longer-peptides). These results provide a model for how viruses and cancer-associated mutations targeting TAP interfaces can affect MHC-I antigen presentation, and how the IFN-γ pathway alters MHC-I antigen presentation via the kinetics of peptide transport.

Abstract
The host immune system plays a crucial role in multiple types of cancer, including non-small-cell lung cancer (NSCLC). Transporter associated with antigen processing (TAP) protein heterodimer complexes might promote intracellular antigen peptide binding with class I major histocompatibility complex (MHC-I) molecules, and in recent years, TAP1 and TAP2 have been reported to be associated with multiple cancer risks. In the current study, we investigated the association of single-nucleotide polymorphisms (SNPs) in TAP1 and TAP2 with NSCLC in a Han Chinese population. Six and seven TAP1 and TAP2 SNPs, respectively, were genotyped and analysed in healthy controls and NSCLC patients. Based on our data, none of the six SNPs in TAP1 is associated with NSCLC risk (P > 0.0038). However, rs2228396 alleles in TAP2 were significantly different between NSCLC patients and healthy controls, and the A allele might be associated with an increased risk of this cancer (P = 0.001, OR = 1.65, 95%CI: 1.23 ∼ 2.21). Moreover, the genotype frequencies of rs2228396 were significantly different between patients and healthy controls (P = 7 × 10-4). Additionally, TAP2 rs241441 alleles exhibited a trend of difference between NSCLC patients and healthy controls, with the C allele possibly being associated with increased risk of NSCLC (P = 0.013; OR = 1.30, 95%CI: 1.06 ∼ 1.60). Moreover, the genotypes of rs241441 in TAP2 showed a significant difference between NSCLC patients and healthy controls (P = 1 × 10-4). In haplotype analysis, the TAP2 SNP haplotype (CAC, TAP2*0102) was significantly associated with increased NSCLC risk in the Han Chinese population (P = 0.003; OR = 1.57, 95%CI: 1.17 ∼ 2.10). Our results indicate that TAP2 SNPs (rs2228396 and rs241441) have a potential role in NSCLC pathogenesis.

Abstract
The host immune system plays an important role in infectious diseases and cancers. The heterodimer formed by transporter associated with antigen presenting (TAP)1 and TAP2 is responsible for intracellular peptide loading onto MHC-I molecules. Studies have shown that single-nucleotide polymorphisms (SNPs) in TAP genes might affect the expression and function of TAP and be associated with cancer risk. We aimed to investigate the association of SNPs in the TAP1 and TAP2 genes with cervical intraepithelial neoplasia (CIN) and cervical cancer (CC) in a Chinese Han population. Six SNPs in the TAP1 gene and seven in the TAP2 gene were selected. The 13 SNPs were genotyped in 1255 healthy individuals, 575 patients with CIN and 1034 patients with CC using the SNaPshot assay. The association between these SNPs and CIN and CC risk was analysed. The allelic and genotypic distributions of rs41549617 and rs1135216 showed significant differences between the control and CC groups (P < 0.0038). The T allele of rs41549617 was associated with a decreased risk of CC (OR = 0.476, 95%CI: 0.286-0.791). Moreover, the G allele of rs1135216 appears to be associated with a decreased risk of CC (OR = 0.746; 95%CI: 0.632-0.881). The allele and genotype distribution of rs241441 showed a significant difference between the control and CC groups (P < 0.0038), and the rs241441 G allele was associated with an increased risk of CC (OR = 1.232, 95%CI: 1.092-1.398). In addition, the results of the association between TAP alleles and CC showed that TAP1*020101 and TAP1*0301 have an association with CC (P = 0.001 and P = 0.002, respectively). Our results demonstrate that the TAP1 and TAP2 genes are associated with CC in the Chinese Han population.

Abstract
Lung cancer is strongly associated with cigarette smoking; nevertheless some never-smokers develop cancer. Immune eradication of cancer cells is dependent on polymorphisms of HLA class I molecules and antigen-processing machinery (APM) components. We have already published highly significant associations of single nucleotide polymorphisms (SNPs) of the ERAP1 gene with non-small cell lung cancer (NSCLC) in Chinese, but not in Polish populations. However, the smoking status of participants was not known in the previous study. Here, we compared the distribution of APM polymorphic variants in larger cohorts of Polish patients with NSCLC and controls, stratified according to their smoking status. We found significant but opposite associations in never-smokers and in smokers of all tested SNPs (rs26653, rs2287987, rs30187, and rs27044) but one (rs26618) in ERAP1. No significant associations were seen in other genes. Haplotype analysis indicated that the distribution of many ERAP1/2 haplotypes is opposite, depending on smoking status. Additionally, haplotypic combination of low activity ERAP1 and the lack of an active form of ERAP2 seems to favor the disease in never-smokers. We also revealed interesting associations of some APM polymorphisms with: age at diagnosis (ERAP1 rs26653), disease stage (ERAP1 rs27044, PSMB9 rs17587), overall survival (ERAP1 rs30187), and response to chemotherapy (ERAP1 rs27044). The results presented here may suggest the important role for ERAP1 in the anti-cancer response, which is different in smokers versus never-smokers, depending to some extent on the presence of ERAP2, and affecting NSCLC clinical course.

Abstract
Tuberculosis (TB) is a common infectious disease, and the present study aims to explore the associations of single nucleotide polymorphisms (SNPs) at rs1135216 and rs1057141 of transporter-associated antigen processing (TAP1) and rs2228396 of TAP2 with pulmonary tuberculosis (PTB) risk. A case-control study including 168 smear-positive PTB cases and 251 controls was conducted. Genotyping of the SNPs at rs1135216, rs1057141 and rs2228396 was performed, and their associations with PTB risk were analysed with SPSS software version 19.0. After conducting stratification for age, a significant association was detected for rs1057141 with increased PTB risk (OR = 0.17, 95% CI 0.04-0.79) among those aged ≥60 years. For those aged <60 years, a marginally significant association was detected between rs1135216 TC/CC and PTB risk (OR = 1.97, 95% CI 0.93-4.19). Haplotype analysis revealed that the haplotype AT at rs1135216 and rs2228396, as well as AAT at rs1057141, rs1135216 and rs2228396, was associated with increased PTB risk, and the ORs were 2.83 (95% CI 1.30-6.14) and 2.89 (95% CI 1.34-6.27), respectively. Rs1057141 is a genetic predictor of reduced PTB risk for those aged ≥60 years, while rs1135216 might be a potential genetic predictor for those aged <60 years. Haplotype AT at rs1135216 and rs2228396, as well as AAT at rs1057141, rs1135216 and rs2228396, is a genetic marker that may predict PTB risk.

Abstract
BACKGROUND Basal cell carcinoma (BCC) of the skin is the most common form of human cancer, with more than 90% of tumours presenting with clear genetic activation of the Hedgehog pathway. However, polygenic risk factors affecting mechanisms such as DNA repair and cell cycle checkpoints or which modulate the tumour microenvironment or host immune system play significant roles in determining whether genetic mutations culminate in BCC development. We set out to define background genetic factors that play a role in influencing BCC susceptibility via promoting or suppressing the effects of oncogenic drivers of BCC. METHODS We performed genome-wide association studies (GWAS) on 17,416 cases and 375,455 controls. We subsequently performed statistical analysis by integrating data from population-based genetic studies of multi-omics data, including blood- and skin-specific expression quantitative trait loci and methylation quantitative trait loci, thereby defining a list of functionally relevant candidate BCC susceptibility genes from our GWAS loci. We also constructed a local GWAS functional interaction network (consisting of GWAS nearest genes) and another functional interaction network, consisting specifically of candidate BCC susceptibility genes. RESULTS A total of 71 GWAS loci and 46 functional candidate BCC susceptibility genes were identified. Increased risk of BCC was associated with the decreased expression of 26 susceptibility genes and increased expression of 20 susceptibility genes. Pathway analysis of the functional candidate gene regulatory network revealed strong enrichment for cell cycle, cell death, and immune regulation processes, with a global enrichment of genes and proteins linked to TReg cell biology. CONCLUSIONS Our genome-wide association analyses and functional interaction network analysis reveal an enrichment of risk variants that function in an immunosuppressive regulatory network, likely hindering cancer immune surveillance and effective antitumour immunity.

Genetic polymorphisms of proteasome subunit genes of the MHC-I antigen-presenting system are associated with cervical cancer in a Chinese Han population. Hum Immunol 2020; 81:445-451. [PMID: 32684411 DOI: 10.1016/j.humimm.2020.07.002] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2020] [Revised: 06/17/2020] [Accepted: 07/05/2020] [Indexed: 01/10/2023]
Abstract
Proteasome subunit beta types 8 and 9 (PSMB8, PSMB9) play critical roles in the human leukocyte antigen class I (HLA I)-presenting system. Studies have suggested that polymorphisms in the PSMB8 and PSMB9 genes may influence the immune functions of PSMB8 and PSMB9, and thus be associated with various human cancers. We investigated associations involving single nucleotide polymorphisms (SNPs) rs2071543 in PSMB8, rs1351383, rs17587 and rs2127675 in PSMB9 and risk of cervical intraepithelial neoplasia (CIN) and cervical cancer in a Chinese Han population. A total of 543 patients with CIN, 1008 patients with cervical cancer, and 1120 healthy individuals were enrolled. Agena MassArray was used for SNP genotyping of PSMB8 and PSMB9. Associations involving these SNPs and risk of CIN and cervical cancer were analysed. Our results showed that the PSMB8 T/T and T/G genotypes of rs2071543 may be associated with a higher risk of CIN (P = 0.011, OR = 1.35,95% CI: 1.07-1.70) and cervical cancer (P = 0.006, OR = 1.31, 95% CI: 1.08-1.59). For rs17587, the A allele (P = 0.001, OR = 1.303, 95% CI: 1.115-1.522), and the A/A and A/G genotypes (P = 0.001, OR = 1.36, 95% CI: 1.13-1.63) may be risk factors for cervical cancer. These results indicated that PSMB8 rs2071543 might influence susceptibility to CIN and cervical cancer, and PSMB9 rs17587 might influence cervical cancer susceptibility in a Chinese Han population.

Abstract
Human leukocyte antigen (HLA) class I molecules of the human major histocompatibility complex (MHC) play an important role in modulating immune response. HLA class I molecules present antigenic peptides to CD8+ T cells and thereby play a role in the immune surveillance of cells infected with viruses. TAP1 and TAP2 are MHC-II-encoded genes necessary for the generation of a cellular immune response and polymorphism of these genes can influence the specificity of peptides preferentially presented by the MHC class I molecules and the outcome of the immune response. Several studies implicated genetic variation in TAP genes to various immune-mediated and infectious diseases. To determine the correlation between HIV-1 infection and the TAP1 and TAP2 genes polymorphisms, we performed PCR–RFLP assay of these genes in 500 HIV-1 seropositives and the matched seronegative individuals. Statistical analysis of the data disclosed no correlation between TAP1 (C/T intron 7) gene polymorphism and HIV-1/AIDS disease. However, the current results demonstrated that the heterozygous A/G [OR (95% CI) 1.39 (1.06–1.83), P = 0.0171] and homozygous G/G [OR (95% CI) 3.38(1.56–7.46), P = 0.0010] variants of TAP2 (A/G exon 11) (T665A) gene are positively associated with an increased risk of HIV-1/AIDS infection. This case–control analysis might suggest a possible role of TAP2 (A/G exon 11) (T665A) gene in the susceptibility to HIV-1 infection and disease outcome among North Indian patients.

Abstract
The aim of this study was to explore the experiences of nurses providing end-of-life care to patients with hematologic malignancies, in a hematology oncology setting, in an acute general hospital. A qualitative hermeneutic phenomenological design was used, and 2 sets of semistructured interviews were conducted with 5 female nurses. The transcribed texts were analyzed using Interpretative Phenomenological Analysis. Two main themes emerged: "battling against medical futility" and "struggling with the emotional burden of care." Nurses perceived that the transfer of these patients at end of life to intensive critical care settings, coupled with the particularly aggressive treatments and corresponding symptom burden, prevented them from experiencing a dignified death. Consequently, nurses struggled with a gamut of emotions that included feelings of helplessness, distress, and compassion fatigue. Providing nursing care at end of life was perceived to be particularly challenging with the younger patients or with those who reminded them of family members. The findings highlight the unique challenges experienced by these nurses and the need to support them in their work with patients having hematologic malignancies at end of life within a well-resourced setting.

Abstract
The findings regarding the relation of transporter associated with antigen processing (TAP) to cancer risk have been inconsistent. The aim of this study was to comprehensively evaluate the association between TAP2 rs241447 polymorphism and cancer susceptibility. A meta-analysis of nine investigations with 2800 cases and 1620 controls was conducted to gain a better understanding of the effect of TAP2 rs241447 polymorphism on cancer risk. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to evaluate the strength of the correlation between TAP2 gene polymorphism and cancer susceptibility. The pooled results from TAP2 rs241447 polymorphism showed a decreased risk of cancer in two dominant genetic models (GG + AG vs AA: OR = 0.86, 95% CI, 0.75-0.99; AG vs AA: OR = 0.85, 95% CI, 0.73-0.99). From the subgroup analysis, decreased cancer susceptibility was found in Caucasians (GG + AG vs AA: OR = 0.82, 95% CI, 0.68-0.99), especially among the subgroup of cervical carcinoma (GG + AG vs AA: OR = 0.82, 95% CI, 0.69-0.96; AG vs AA: OR = 0.83, 95% CI, 0.70-0.99). Overall, the results suggest that TAP2 rs241447 polymorphism contributes to decreased cancer susceptibility.

Abstract
Background: Multiple myeloma is a plasma cell dyscrasia characterized by transformation of B cells into malignant cells. Although there are data regarding the molecular pathology of multiple myeloma, the molecular mechanisms of the disease have not been fully elucidated. Aims: To investigate the gene expression profiles in bone marrow myeloma cells via RNA-sequencing technology. Study Design: Cell study. Methods: Myeloma cells from four patients with untreated multiple myeloma and B cells from the bone marrow of four healthy donors were sorted using a FACSAria II flow cytometer. The patient pool of myeloma cells and the control pool of B cells were the two comparative groups. A transcriptome analysis was performed and the results were analyzed using bioinformatics tools. Results: In total, 18.806 transcripts (94.4%) were detected in the pooled multiple myeloma patient cells. A total of 992 regions were detected as new exon candidates or alternative splicing regions. In addition, 490 mutations (deletions or insertions), 1.397 single nucleotide variations, 415 fusion transcripts, 132 frameshift mutations, and 983 fusions, which were reported before in the National Center for Biotechnology Information, were detected with unknown functions in patients. A total of 35.268 transcripts were obtained (71%) (25.355 transcripts were defined previously) in the control pool. In this preliminary study, the first 50 genes were analyzed with the MSigDB, Enrichr, and Panther gene set enrichment analysis programs. The molecular functions, cellular components, pathways, and biological processes of the genes were obtained and statistical values were determined using bioinformatics tools and are presented as a supplemental file. Conclusion: EEF1G, ITM2C, FTL, CLPTM1L, and CYBA are identified as possible candidate genes associated with myelomagenesis.

Abstract
OBJECTIVE Transporter associated with antigen processing protein (TAP) is a heterodimer protein consist of TAP1 and TAP2, act a pivotal part in the immune surveillance. In recent days, controversial relationships were reported between TAP polymorphisms and cancer risk, thus, a systematic meta-analysis was performed to resolve this discrepancy. METHODS We searched the PubMed, EMbase, Web of Science, CNKI and Wanfang databases, the cited references were also manually searched again, covering all the papers published until March 25, 2018. Quality assessment was conducted using the Newcastle-Ottawa Scale. All the meta-analysis was conducted with Stata version 12.0 software to assess the strength of the association. RESULTS 4719 cases and 4215 controls from 24 case-control studies related to TAP polymorphisms were enrolled. There was no significant association between TAP1-rs1135216, TAP1-rs4148873, TAP2-rs2228396, TAP2-rs241447 and TAP2-rs4148873 and cancer sensibility. Interestingly, a significant positive association was observed between TAP2 rs4148876 C/T polymorphism and increase cancer risk in homozygote and recessive models. Further in-silico results indicated the expression of TAP2 in cancer tissue is higher than that in normal tissue (cervical cancer, TPM = 70.2 vs. 24.0 respectively, P < 0.01; acute myeloid leukemia, TPM = 52.5 vs. 8.8 respectively, P < 0.01), and influence the survival time of acute myeloid leukemia patients (Log-rank P < 0.05). CONCLUSIONS Our finding suggested that TAP1-rs1135216, TAP1-rs4148873, TAP2-rs2228396, TAP2-rs241447 and TAP2-rs4148873 might not be involved in cancer risk, but the T allele of TAP2-rs4148876 might be a potential biomarker for judging cancer risk, and larger-scale studies are required to confirm our findings.

Abstract
OBJECTIVES Ankylosing spondylitis (AS) is a chronic inflammatory joint disease. The transporter associated with antigen processing (TAP) has been identified to play an important role in immune response as well as the HLA-associated diseases. The aim of our meta-analysis was to investigate the contribution of TAP (TAP1 and TAP2) polymorphisms to the risk of AS. METHODS Meta-analyses were performed between 2 polymorphisms in TAP1 (TAP1-333, -637) and 3 polymorphisms in TAP2 (TAP2-379, -565, and -665) and AS. RESULTS The meta-analyses were involved with 6 studies with 415 cases and 659 controls. Significant association was found between TAP1-333Val, TAP1-637Gly, and TAP2-565Thr and AS compared with combined control group (TAP1-333Val: p = 0.009, OR = 1.40, 95% CI 1.09-1.80; TAP1-637Gly: p = 0.002, OR = 1.48, 95% CI 1.15-1.91; p = 0.03, OR = 1.38, 95% CI 1.04-1.84). Subgroup analysis shown that significant association was only found in AS when compared with HLA-B27-negative controls (TAP1-333Val: p = 0.004, OR = 1.53, 95% CI 1.14-2.06; TAP1-637Gly: p = 0.004, OR = 1.52, 95% CI 1.15-2.02; p = 0.02, OR = 1.56, 95% CI 1.09-2.24), but not in AS when compared with HLA-B27-positive controls (p > 0.05). Moreover, no significant associations were found between haplotypes in TAP1 and TAP2 in both the combined and the subgroup analyses (p > 0.05). CONCLUSIONS TAP1-333Val, TAP1-637Gly, and TAP2-565Thr were likely to be associated with AS.

Abstract
OBJECTIVE Explore the feasibility of allo- hemopietic stem cell transplants in treating patients with B cell acute lymphocytic leukemia. METHODS Between september 2006 and February 2011, fifteen patients with B cell acute lymphocytic leukemia (ALL) were treated by allo-hemopietic stem cell transplants (HSCT). Stem cell sources were peripheral blood. Six patients were conditioned by busulfan (BU) and cyclophosphamide (CY) and nine patients were conditioned with TBI and cyclophosphamide (CY). Graft versus host disease (GVHD) prophylaxis regimen consisted of cyclosporine A (CSA), methotrex ate (MTX) and mycophenolatemofetil (MMF). RESULTS Patients received a median of 7.98×10⁸·kg⁻¹ (5.36-12.30×10⁸·kg⁻¹) mononuclear cells (MNC). The median time of ANC>0.5×10⁹/L was day 12 (10-15), and PLT>20.0×10⁹/L was day 13 (11-16). Extensive acute GVHD occurred in 6 (40.0%) patients, and extensive chronic GVHD was recorded in 6 (40.0%) patients. Nine patients were alive after 2.5-65 months follow-up. CONCLUSION Allogeneic stem cell transplant could be effective in treating patients with B cell acute lymphocytic leukemia.
