Abstract
Natural killer (NK) cells play essential roles in the tumor development, diagnosis, and prognosis of tumors. In this study, we aimed to establish a reliable signature based on marker genes in NK cells, thus providing a new perspective for assessing immunotherapy and the prognosis of patients with gastric cancer (GC). We analyzed a total of 1560 samples retrieved from the public database. We performed a comprehensive analysis of single-cell RNA-sequencing (scRNA-seq) data of gastric cancer and identified 377 marker genes for NK cells. By performing Cox regression analysis, we established a 12-gene NK cell-associated signature (NKCAS) for the Cancer Genome Atlas (TCGA) cohort, that assigned GC patients into a low-risk group (LRG) or a high-risk group (HRG). In the TCGA cohort, the areas under curve (AUC) value were 0.73, 0.81, and 0.80 at 1, 3, and 5 years. External validation of the predictive ability for the signature was then validated in the Gene Expression Omnibus (GEO) cohorts (GSE84437). The expression levels of signature genes were measured and validated in GC cell lines by real-time PCR. Moreover, NKCAS was identified as an independent prognostic factor by multivariate analysis. We combined this with a variety of clinicopathological characteristics (age, M stage, and tumor grade) to construct a nomogram to predict the survival outcomes of patients. Moreover, the LRG showed higher immune cell infiltration, especially CD8+ T cells and NK cells. The risk score was negatively associated with inflammatory activities. Importantly, analysis of the independent immunotherapy cohort showed that the LRG had a better prognosis and immunotherapy response when compared with the HRG. The identification of NK cell marker genes in this study suggests potential therapeutic targets. Additionally, the developed predictive signatures and nomograms may aid in the clinical management of GC.

Funct Integr Genomics 2023; 23:177. [PMID: 37225895 DOI: 10.1007/s10142-023-01103-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2023] [Revised: 05/05/2023] [Accepted: 05/15/2023] [Indexed: 05/26/2023]
Abstract
Esophageal squamous cell carcinoma (ESCC) is a prevalent cancer type with a poor prognosis. As a form of programmed cell death, pyroptosis has been implicated in cancer growth, invasion, and metastasis. To investigate the relationship between pyroptosis and the prognosis of ESCC, we analyzed the expression profiles and clinical data of patients with ESCC, obtained from the Gene Expression Omnibus and The Cancer Genome Atlas databases, using bioinformatics analysis. Univariate Cox, multivariate Cox, and LASSO Cox regression analyses were conducted to develop a pyroptosis-related prognostic model (riskScore). CIBERSORT and MCPcounter algorithm evaluated the proportion of various immune infiltrating cells. Tissues from 16 patients were collected to verify the expression of key pyroptosis-related genes (PRGs) using real-time quantitative PCR (RT-qPCR), western blot, and immunohistochemical assays. Additionally, functional assays were performed in ESCC cell lines KYSE-150 and ECA-109 to examine the role of key PRGs. Among 25 pyroptosis-related regulators, 12 genes exhibited differential expression between tumor and normal tissues. Based on the differential expression of PRGs, we identified two subgroups with distinct clinical and molecular features. We further established a pyroptosis-related model with high prognostic value. In addition, we found a significant association of PRGs and riskScore with immune cell infiltration and the response rate of immunotherapy. Furthermore, we confirmed the low expression of WFDC12 in ESCC. Cellular assays demonstrated that the knockdown of WFDC12 in ESCC cell lines promoted cell proliferation and migration. Collectively, our findings highlight the critical role of PRGs in the development and prognosis of ESCC, while our riskScore could accurately predict the prognosis and immunogenicity of ESCC. Finally, our preliminary evidence suggests a protective role of WFDC12 in ESCC in vitro.

Abstract
PURPOSE Cancer testis antigens (CTAs) are optimal tumor diagnostic markers and involved in carcinogenesis. However, colorectal cancer (CRC) related CTAs are less reported with impressive diagnostic capability or relevance with tumor metabolism rewiring. Herein, we demonstrated CRC-related CTA, Protamine 1 (PRM1), as a promising diagnostic marker and involved in regulation of cellular growth under nutrient deficiency. METHODS Transcriptomics of five paired CRC tissues was used to screen CRC-related CTAs. Capability of PRM1 to distinguish CRC was studied by detection of clinical samples through enzyme linked immunosorbent assay (ELISA). Cellular functions were investigated in CRC cell lines through in vivo and in vitro assays. RESULTS By RNA-seq and detection in 824 clinical samples from two centers, PRM1 expression were upregulated in CRC tissues and patients` serum. Serum PRM1 showed impressive accuracy to diagnose CRC from healthy controls and benign gastrointestinal disease patients, particularly more sensitive for early-staged CRC. Furthermore, we reported that when cells were cultured in serum-reduced medium, PRM1 secretion was upregulated, and secreted PRM1 promoted CRC growth in culture and in mice. Additionally, G1/S phase transition of CRC cells was facilitated by PRM1 protein supplementation and overexpression via activation of PI3K/AKT/mTOR pathway in serum deficient medium. CONCLUSIONS In general, our research presented PRM1 as a specific CRC antigen and illustrated the importance of PRM1 in CRC metabolism rewiring. The new vulnerability of CRC cells was also provided with the potential to be targeted in future. Diagnostic value and grow factor-like biofunction of PRM1 A represents the secretion process of PRM1 regulated by nutrient deficiency. B represents activation of PI3K/AKT/mTOR pathway of secreted PRM1.

Abstract
Background Members of the melanoma-associated antigen-A (MAGE-A) subfamily are overexpressed in many cancers and can drive cancer progression, metastasis, and therapeutic recurrence. Objective This study is the first comprehensive meta-analysis evaluating the prognostic utility of MAGE-A members in different cancers. Methods A systematic literature search was conducted in PubMed, Google Scholar, Science Direct, and Web of Science. The pooled hazard ratios with 95% confidence intervals were estimated to evaluate the prognostic significance of MAGE-A expression in various cancers. Results In total, 44 eligible studies consisting of 7428 patients from 11 countries were analysed. Univariate and multivariate analysis for overall survival, progression-free survival, and disease-free survival showed a significant association between high MAGE-A expression and various cancers (P < 0.00001). Additionally, subgroup analysis demonstrated that high MAGE-A expression was significantly associated with poor prognosis for lung, gastrointestinal, breast, and ovarian cancer in both univariate and multivariate analysis for overall survival. Conclusion Overexpression of MAGE-A subfamily members is linked to poor prognosis in multiple cancers. Therefore, it could serve as a potential prognostic marker of poor prognosis in cancers.

Abstract
Laryngeal squamous cell carcinoma (LSCC) is one of the most common malignant tumors in the head and neck area. Melanoma-associated antigens A (MAGE-A) are strictly tumor-specific and are expressed in several types of tumors. To date, no studies have reported the potential of MAGE-A genes as markers for circulating tumor cells (CTCs) in patients with LSCC. The present study aimed to evaluate the expression and the possible prognostic significance of MAGE-A in the peripheral blood of patients with LSCC. In the present study, the expression of MAGE-A genes was determined by multiplex semi-nested PCR and restriction endonuclease treatment of the peripheral blood of patients with LSCC. The association between MAGE-A gene expression and clinicopathological parameters and prognosis was evaluated. The results demonstrated that the expression of MAGE-A was associated with the predictors that indicate poor prognosis. The expression levels of MAGE-A and each individual MAGE-A gene were also associated with a shorter overall survival time of patients with LSCC. In conclusion, the results of the present study suggested that the expression of MAGE-A genes may be a potential prognostic marker for patients with LSCC.

Abstract
During the last 60 years numerous significant attempts have been made to achieve a widely acceptable terminology and histological grading for laryngeal squamous intraepithelial lesions. While dysplasia was included in the pathology of the uterine cervix already in 1953, the term dysplasia was accepted in laryngeal pathology first after the Toronto Centennial Conference on Laryngeal Cancer in 1974. In 1963 Kleinsasser proposed a three-tier classification, and in 1971 Kambic and Lenart proposed a four-tier classification. Since then, four editions of the World Health Organisation (WHO) classification have been proposed (1978, 1991, 2005 and 2017). Several terms such as squamous intraepithelial neoplasia (SIN) and laryngeal intraepithelial neoplasia (LIN) are now being abandoned and replaced by squamous intraepithelial lesions (SIL). The essential change between the 2005 and 2017 WHO classifications is the attempt to induce a simplification from a four- to a two-tier system. The current WHO classification (2017) thus recommends the use of a two-tier system with reasonably clear histopathological criteria for the two groups: low-grade and high-grade dysplasia. Problems with interobserver variability apart, subjectivities and uncertainties remain, but to a lesser degree. Ongoing and additional molecular studies may help to clarify underlying events that will increase our understanding and possibly can facilitate our attempts to obtain an even better classification. The classification needs to be easier for the general pathologist to perform and easier for the clinician to interpret. These two objectives are equally important to provide each patient the best personalised treatment available for squamous intraepithelial lesions.

Abstract
Our goal was to explore the association of melanoma-associated antigen-A (MAGE-A) gene expression with clinicopathological parameters and survival rates in patients with non-small-cell lung cancer (NSCLC) who had surgery. A systematic search of EMBASE, PubMed, Web of Science and The Cochrane Library databases was performed through 20 April 2019. The combined risk ratios (RRs) and hazard ratios (HRs) with their corresponding 95% confidence intervals (CIs) were calculated to assess the association of MAGE-A gene expression with clinicopathological characteristics and prognosis of patients with resected NSCLC, respectively. All statistical analyses were performed with Stata software, version 12.0. A total of 9 articles involving 1538 patients were included in our meta-analysis; most of the studies were from Asian countries. The results indicated that the expression of the MAGE-A gene was significantly correlated with lymph node metastases (RR 1.21, 95% CI 1.09-1.34; P = 0.001), high tumour-node-metastasis stage (RR 1.24, 95% CI 1.12-1.38; P < 0.001), histological type (squamous cell carcinoma) (RR 1.82, 95% CI 1.15-2.87; P = 0.01), poor overall survival (HR 2.11, 95% CI 1.73-2.57; P < 0.001) and cancer-specific survival (HR 1.76, 95% CI 1.12-2.78; P = 0.015). MAGE-A gene expression is related to tumour development and metastasis and is more prevalent in squamous cell carcinomas of the lung; besides, it is an independent prognostic factor for patients with resected NSCLC.

Abstract
PURPOSE Abnormal DNA methylation plays an important role in clinical diagnosis and prognosis of various tumors. DNA methylation is catalyzed by DNA methyltransferase (DNMT). However, the methylation status of MAGE-A1 and MAGE-A3 promoter regions in LSCC is unclear. To investigate the methylation levels of MAGE-A1, -A3 in LSCC and corresponding normal tissues. The expression of DNMTs (DNMT1, DNMT3a and DNMT3b) in LSCC and the relationship between the methylation status of MAGE-A1, -A3 were analyzed. MATERIALS AND METHODS We examined methylation status of MAGE-A1, -A3 in LSCC by using MSP. Meanwhile, the expression level of DNMTs in LSCC was detected by immunohistochemistry. And further analysis the correlation between DNMTs expression level and methylation status of MAGE-A1 and MAGE-A3. RESULTS The unmethylation rate of MAGE-A1, -A3 were 39.62% and 46.23%. The expression of DNMTs was 33.02% to 37.74%. The level of demethylation of MAGE-A1 and MAGE-A3 were negative related to DNMTs protein. MAGE-A1 and MAGE-A3 unmethylation status and DNMT3a expression were independent prognostic factors for LSCC. CONCLUSIONS The DNMTs may participate in the methylation process of MAGE-A1 and MAGE-A3, which may play an important role in the occurrence and development of LSCC.

Abstract
BACKGROUND The expression and methylation status of oncogenes are closely related to the onset and progression of cancer. AIMS To explore the role and methylation status of melanoma-associated antigen-A11 in the pathogenesis of esophageal squamous cell carcinoma. METHODS 116 esophageal squamous cell carcinoma patients with tumor tissues and corresponding adjacent normal tissues were obtained. The expression level and methylation status of melanoma-associated antigen-A11 in esophageal cancer cell lines and esophageal squamous cell carcinoma tissues were determined respectively. RESULTS Significant up-regulation of melanoma-associated antigen-A11 was detected in esophageal cancer cell lines and esophageal squamous cell carcinoma tissues. Up-regulation of melanoma-associated antigen-A11 contributed to proliferation and invasion in cancer cells. Hypomethylation of the CpG site was associated with pathological differentiation, clinical stage, tumor size, lymph node metastasis and distant metastasis. Esophageal squamous cell carcinoma patients in stage III and IV, with high expression of melanoma-associated antigen-A11 or hypomethylation of the CpG site within the promoter demonstrated poor survival. CONCLUSION Melanoma-associated antigen-A11 is up-regulated in esophageal squamous cell carcinoma at least partly by hypomethylation of the CpG site within the promoter and this hypomethylation may affect the prognosis of esophageal squamous cell carcinoma patients.

Abstract
Melanoma antigen-A11 (MAGE-A11) is a low-abundance, primate-specific steroid receptor coregulator in normal tissues of the human reproductive tract, which plays an important role in tumorigenesis. Single-nucleotide polymorphisms (SNPs) have been shown to contribute to cancer risk and prognosis. However, the role of SNPs of MAGE-A11 in renal cell carcinoma (RCC) has not been established. Two intronic SNPs (rs6641352 and rs6540341) of MAGE-A11 have been screened to assess their associations with RCC risk and prognosis in a case control study. We found that rs6641352 was associated with RCC susceptibility in the dominant model (TC/CC vs. TT, adjusted odds ratio = 1.315, 95% confidence interval [CI] = 1.089-1.588) and with survival of RCC in the recessive model (CC vs. TT/TC, adjusted hazard ratio = 3.526, 95% CI = 1.072-11.595). For the SNP rs6540341, individuals with the T allele could have a critically increased risk of RCC (adjusted odds ratio = 1.301, 95% CI = 1.081-1.564, P = 0.005 in the dominant model). However, there was no significant association between rs6540341 and RCC survival. Hence, rs6641352 in MAGE-A11 may contribute to the genetic susceptibility and prognosis for RCC and act as a biomarker for RCC occurrence and prognosis.

Abstract
OBJECTIVE To evaluate the clinical characteristics and prognostic significance of MAGE-A11 and transcription factors (SP1, TFCP2 and ZEB1) in patients with esophageal squamous cell carcinoma (ESCC). METHODS To assess the expression of MAGE-A11 and transcription factors (SP1, TFCP2 and ZEB1) in 121 ESCC samples were respectively detected by immunohistochemical method. RESULTS The results showed MAGE-A11 and transcription factors (SP1,TFCP2 and ZEB1) expression were associated with some clinical features in patients, such as pathological differentiation, tumor size, clinical stage, lymph node metastasis and distant metastasis. Kaplan-Meier analysis showed that patients with ESCC having high MAGE-A11 and transcription factors (SP1,TFCP2 and ZEB1) expression had a worse prognosis compared to the patients with low expression. Multivariate Cox proportional hazards regression model revealed that MAGE-A11 expression, TFCP2 expression, lymph node metastasis and distant metastasis were independently associated with ESCC patients' survival. CONCLUSIONS High expression of MAGE-A11 and transcription factors (SP1,TFCP2 and ZEB1) in ESCC tissues suggests promoting ESCC progression and poor prognosis, co-expression of MAGE-A11 and transcription factors even worse.

MAGE-A expression in oral and laryngeal leukoplakia predicts malignant transformation. Mod Pathol 2019; 32:1068-1081. [PMID: 30936424 DOI: 10.1038/s41379-019-0253-5] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2018] [Revised: 02/17/2019] [Accepted: 02/27/2019] [Indexed: 12/21/2022]
Abstract
Leukoplakia is a potential precursor of oral as well as laryngeal squamous cell carcinoma. Risk assessment of malignant transformation based on the grade of dysplasia of leukoplakia often does not lead to reliable results. However, oral squamous cell carcinoma, laryngeal squamous cell carcinoma, and leukoplakia express single or multiple members of the melanoma-associated antigens A (MAGE-A) family, while MAGE-A are absent in healthy mucosal tissue. The present study aimed at determining if there is an association between the expression of MAGE-A in leukoplakia and malignant transformation to oral or laryngeal squamous cell carcinoma. Paraffin-embedded tissues of 205 oral and laryngeal leukoplakia, 90 corresponding tumors, and 40 healthy oral mucosal samples were included in the study. The grade of dysplasia of the leukoplakia samples was determined histopathologically. The leukoplakia samples were divided into lesions that transformed to oral and laryngeal squamous cell carcinoma (n = 91) and lesions that did not (n = 114) during a 5 years follow-up. The expression of MAGE-A3/6 and MAGE-A4 was analyzed by real-time RT-PCR. The expression of MAGE-A 1-4, 6, and 12 was determined by immunohistochemistry. A total of 59.3% of the transforming leukoplakia expressed at least one of the examined antigens as opposed to an expression rate of 3.5% of all non-transforming leukoplakia. There was no MAGE-A expression in healthy oral mucosa. The risk of malignant transformation was statistically significantly associated with MAGE-A expression in immunohistochemistry (p < 0.001) and real-time RT-PCR (MAGE-A3/6, p = 0.001; MAGE-A4, p = 0.002) analyses. There was no significant association between MAGE-A expression and the grade of dysplasia ("low-grade", D0/D1; "high-grade", D2/D3) in immunohistochemistry (p = 0.412) and real-time RT-PCR (MAGE-A3/6, p = 0.667; MAGE-A4, p = 0.756). It seems that the analysis of the MAGE-A expression profile may support the identification of leukoplakia at risk for malignant transformation. Therefore, efforts should be made to establish this analysis as a routine procedure in addition to conventional histopathology.

Abstract
Melanoma antigen-A11 (MAGE-A11) is an X-linked and primate-specific steroid hormone receptor transcriptional coregulator and proto-oncogenic protein whose increased expression promotes the growth of prostate cancer. The MAGEA11 gene is expressed at low levels in normal human testis, ovary, and endometrium, and at highest levels in castration-resistant prostate cancer. Annotated genome predictions throughout the surviving primate lineage show that MAGEA11 acquired three 5' coding exons unique within the MAGEA subfamily during the evolution of New World monkeys (NWM), Old World monkeys (OWM), and apes. MAGE-A11 in all primates has a conserved FXXIF coactivator-binding motif that suggests interaction with p160 coactivators contributed to its early evolution as a transcriptional coregulator. An ancestral form of MAGE-A11 in the more distantly related lemur has significant amino acid sequence identity with human MAGE-A11, but lacks coregulator activity based on the absence of the three 5' coding exons that include a nuclear localization signal (NLS). NWM MAGE-A11 has greater amino acid sequence identity than lemur to human MAGE-A11, but inframe premature stop codons suggest that MAGEA11 is a pseudogene in NWM. MAGE-A11 in OWM and apes has nearly identical 5' coding exon amino acid sequence and conserved interaction sites for p300 acetyltransferase and cyclin A. We conclude that the evolution of MAGEA11 within the lineage leading to OWM and apes resulted in steroid hormone receptor transcriptional coregulator activity through the acquisition of three 5' coding exons that include a NLS sequence and nonsynonymous substitutions required to interact with cell cycle regulatory proteins and transcription factors.

Abstract
Background MAGE‐A genes belong to the cancer/testis antigens family. The prognostic significance of MAGE‐A expression in the peripheral blood of patients with lung cancer is unknown. Therefore, this study evaluated the expression and possible prognostic significance of MAGE‐A in the peripheral blood of patients with lung cancer. Methods In this study, we detected MAGE‐A gene expression in the peripheral blood of 150 patients with lung cancer and 30 healthy donors using multiplex semi‐nested PCR and analyzed their correlation with clinicopathological risk factors. Results MAGE‐A expression was associated with factors indicating poor prognosis. The expression of MAGE‐A and each individual MAGE‐A gene were also associated with low overall survival in patients with lung cancer. Conclusion The expression of MAGE‐A genes in peripheral blood may act as a poor prognostic marker in patients with lung cancer.

Abstract
MAGE-A9, a well-characterized cancer testis antigen (CTA), belongs to a member of melanoma antigen gene (MAGE) family. In human malignancies, aberrant expression of MAGE genes correlated with poor clinical prognosis, increased tumor growth, metastases, and enrichment in stem cell populations of certain cancers. Cancer stem cells (CSCs) have been proposed to contribute to the major malignant phenotypes of liver cancer, including recurrence, metastasis and chemoresistance. However, expression and potential role of MAGE-A9 in liver cancer stem cells (LCSCs) still remain unclear. In the present study, we first analyzed the expression profiling of MAGE family genes in EpCAM+ and EpCAM- human hepatocellular carcinoma (HCC), based on public Gene Expression Omnibus (GEO) database. Among these examined MAGE members, MAGE-A9 is the only one with significantly higher expression in EpCAM+ HCC specimens as compared with EpCAM- HCC. Quantitative PCR analysis further confirmed that MAGE-A9 expression significantly elevated in a subtype of HCC patients that had features of hepatic stem/progenitor cells with high-level expression of EpCAM and α-fetoprotein (AFP). Moreover, MAGE-A9 displayed remarkably enriched expression in EpCAM+ HCC cells that were sorted by fluorescence-activated cell sorting and cultured HCC cell spheroids with characteristics of stem/progenitor cells. Functional experiments further revealed that MAGE-A9 overexpression promoted cell proliferation, colony formation, migration, chemoresistance, and tumorigenicity in the context of EpCAM+ HCC cells, whereas MAGE-A9 knockdown significantly inhibited anchorage-dependent and spheroid colony formation and in vivo tumorigenicity. Collectively, these data demonstrate that MAGE-A9 functions as an important regulator of LCSCs, and MAGE-A9 may serve as a potential therapeutic target against HCC stem/progenitor cells.

Abstract
Cancer/testis (CT) genes are excellent candidates for cancer immunotherapies because of their restrict expression in normal tissues and the capacity to elicit an immune response when expressed in tumor cells. In this study, we provide a genome-wide screen for CT genes with the identification of 745 putative CT genes. Comparison with a set of known CT genes shows that 201 new CT genes were identified. Integration of gene expression and clinical data led us to identify dozens of CT genes associated with either good or poor prognosis. For the CT genes related to good prognosis, we show that there is a direct relationship between CT gene expression and a signal for CD8+ cells infiltration for some tumor types, especially melanoma.

Abstract
Background In the present study, we aimed to investigate the prognostic value of epithelial membrane protein 1 (EMP-1) gene in patients diagnosed with laryngeal carcinoma (LC). Material/Methods Patients who were pathologically diagnosed with LC were enrolled in the present study. The expression levels of EMP-1 in tumor tissues and corresponding normal tissues collected from the LC patients were detected by semi-reverse transcriptase polymerase chain reaction (semi-RT-PCR). Chi-square analysis was used to evaluate the relationship between EMP-1 expression level and clinical characteristics. Survival analysis for the study population was analyzed by Kaplan-Meier method with log rank test. Additionally, Cox regression model was applied to evaluate the prognostic value of EMP-1 in LC patients. Results 106 LC patients, including 55 men and 51 women, were enrolled in the present study. Semi-RT-PCR demonstrated that the expression level of EMP-1 was decreased in tumor tissues, compared with adjacent normal tissues (p<0.001). Moreover, the level was significantly associated with lymph node metastasis, histological grade, and clinical stage (p<0.05 for all). In addition, low levels of EMP-1 was significantly correlated with poor survival rate (log rank test, p=0.020). Cox regression analysis indicated that EMP-1 was an independent marker for LC prognosis (HR=2.755, 95% CI=1.123–6.760, p=0.027). Conclusions The abnormal expression of EMP-1 may be associated with progression of LC and the gene may act as a prognostic marker for LC.
