Abstract
Identification of ectopic gene activation in cancer cells serves as a basis for both gene signature-guided tumor targeting and unearthing of oncogenic mechanisms to expand the understanding of tumor biology/oncogenic process. Proteins expressed only in germ cells of testis and/or placenta (immunoprivileged organs) and in malignancies are called cancer testis antigens; they are antigenic because of the lack of antigen presentation by those specific cell types (germ cells), which limits the exposure of the proteins to the immune cells. Since the Cancer Testis Antigens (CTAs) are immunogenic and expressed in a wide variety of cancer types, CT antigens have become interesting target for immunotherapy against cancer. Among CT antigens MAGEA family is reported to have 12 members (MAGEA1 to MAGEA12). The current review highlights the studies on MAGEA3 which is a CT antigen and reported in almost all types of cancer. MAGEA3 is well tried for cancer immunotherapy. Recent advances on its functional and immunological aspect warranted much deliberation on effective therapeutic approach, thus making it a more interesting target for cancer therapy.

Abstract
Purpose: A phase I study was conducted to determine safety, clinical efficacy, and antitumor immune responses in patients with advanced non-small cell lung carcinoma (NSCLC) following intratumoral administration of autologous dendritic cells (DC) transduced with an adenoviral (Ad) vector expressing the CCL21 gene (Ad-CCL21-DC). We evaluated safety and tumor antigen-specific immune responses following in situ vaccination (ClinicalTrials.gov: NCT01574222).Experimental Design: Sixteen stage IIIB/IV NSCLC subjects received two vaccinations (1 × 106, 5 × 106, 1 × 107, or 3 × 107 DCs/injection) by CT- or bronchoscopic-guided intratumoral injections (days 0 and 7). Immune responses were assessed by tumor antigen-specific peripheral blood lymphocyte induction of IFNγ in ELISPOT assays. Tumor biopsies were evaluated for CD8+ T cells by IHC and for PD-L1 expression by IHC and real-time PCR (RT-PCR).Results: Twenty-five percent (4/16) of patients had stable disease at day 56. Median survival was 3.9 months. ELISPOT assays revealed 6 of 16 patients had systemic responses against tumor-associated antigens (TAA). Tumor CD8+ T-cell infiltration was induced in 54% of subjects (7/13; 3.4-fold average increase in the number of CD8+ T cells per mm2). Patients with increased CD8+ T cells following vaccination showed significantly increased PD-L1 mRNA expression.Conclusions: Intratumoral vaccination with Ad-CCL21-DC resulted in (i) induction of systemic tumor antigen-specific immune responses; (ii) enhanced tumor CD8+ T-cell infiltration; and (iii) increased tumor PD-L1 expression. Future studies will evaluate the role of combination therapies with PD-1/PD-L1 checkpoint inhibition combined with DC-CCL21 in situ vaccination. Clin Cancer Res; 23(16); 4556-68. ©2017 AACR.

Abstract
Melanoma antigen family A, 3 (MAGE-A3) is a cancer-testis antigen whose expression has been demonstrated in a wide array of malignancies including melanoma, brain, breast, lung and ovarian cancer. In addition, its ability to elicit spontaneous humoral and cellular immune responses has been shown in cancer patients. As antigen-specific immune responses can be stimulated by immunization with MAGE-A3, several clinical trials have used MAGE-A3 vaccines to observe clinical responses. The frequent expressions of this antigen in various tumors and its immunogenicity in cancer patients have led to application of this antigen in cancer immunotherapy. However, the results of recent clinical trials indicate that there is a need for research in the vaccine design, adjuvant selection as well as patient selection criteria.

Abstract
The aim of this study was to detect differences in the expression levels of melanoma-associated antigen D4 (MAGED4) mRNA between non-small cell lung cancer (NSCLC) tissues and normal tissues, and to compare differences in the expression levels of MAGED4 in tumor patients. Patients were grouped according to age, gender, smoking history, tumor size, pathological classification, degree of lung cancer cell differentiation and presence of lymph node metastasis. The expression levels of MAGED4 were detected using real-time fluorescence quantitative PCR. MAGED4 expression was higher in squamous cell carcinomas compared to adenocarcinomas (P<0.05), in poorly differentiated tissues compared to well-differentiated tissues (P<0.05), and in patients with lymph node metastasis compared to patients without lymph node metastasis (P<0.05). MAGED4 may be used as a specific antigen for NSCLC to influence the improvement of diagnosis, prognosis and immunological therapy outcomes in lung cancer patients.

Abstract
Non-small cell lung cancer (NSCLC) is the biggest cancer killer in the United States and worldwide. In 2011, there are estimated to be 221,130 new cases of lung cancer in the United States. Over a million people will die of lung cancer worldwide this year alone. When possible, surgery to remove the tumor is the best treatment strategy for patients with NSCLC. However, even with adjuvant (postoperative) chemotherapy and radiation, more than 40% of patients will develop recurrences locally or systemically and ultimately succumb to their disease. Thus, there is an urgent need for developing superior approaches to treat patients who undergo surgery for NSCLC to eliminate residual disease that is likely responsible for these recurrences. Our group and others have been interested in using immunotherapy to augment the efficacy of current treatment strategies. Immunotherapy is very effective against minimal disease burden and small deposits of tumor cells that are accessible by the circulating immune cells. Therefore, this strategy may be ideally suited as an adjunct to surgery to seek and destroy microscopic tumor deposits that remain after surgery. This review describes the mechanistic underpinnings of immunotherapy and how it is currently being used to target residual disease and prevent postoperative recurrences after pulmonary resection in NSCLC.

Abstract
BACKGROUND Melanoma antigen-encoding gene-1 (MAGE-1), a cancer/testis antigen, has been reported to be expressed in various types of cancer. We investigated the clinicopathological features and prognostic significance of MAGE-1 expression in advanced gastric cancer (AGC). METHODS Immunohistochemical staining for MAGE-1 was performed on surgical specimens obtained from 135 patients with AGC. RESULTS Positive expression of MAGE-1 detected in cytoplasm was observed in 44 of 135 cases (32.6%) in primary tumors and 26 of 96 (27.1%) in lymph node metastases. In noncancerous gastric tissues, apparent MAGE-1 expression was not detected. MAGE-1 in primary tumor was correlated with advanced age (P < 0.001), macroscopic infiltrated type (P = 0.035), and presence of vascular invasion (P = 0.027). The 5-year cancer-specific survival rates of AGC patients with positive MAGE-1 expression were significantly lower than those of patients with negative MAGE-1 (positive: 31.6%, negative: 57.6%, P = 0.038). On multivariate analysis, MAGE-1 expression was not an independent prognostic predictor of AGC (P = 0.064). In differentiated AGC patients, MAGE-1 expression was correlated with advanced age (P = 0.003), macroscopic infiltrated type (P = 0.009), and presence of lymph node metastasis (P = 0.033). The cancer-specific survival rates of differentiated AGC patients with positive MAGE-1 were significantly lower than those of patients with negative MAGE-1 (P = 0.003). Positive MAGE-1 expression was an independent prognostic factor of differentiated AGC patients on multivariate analysis (P = 0.031). CONCLUSIONS These findings suggest that MAGE-1 protein expression can serve as a predictive marker of poor prognosis in differentiated AGC patients.

Abstract
BACKGROUND As mortality from lung cancer is still very high, early detection prior to metastasis is important in clinical settings. We prospectively evaluated the clinical usefulness of a reverse transcription-nested polymerase chain reaction (RT-nested PCR) using melanoma antigen (MAGE) A1-6 genes with tissue samples obtained from the percutaneous needle aspiration (PCNA) biopsies used in the diagnosis of lung cancer. METHODS We enrolled 53 patients with suspected lung cancer based on CT scan (M:F, 39:14; mean age 61 years). A PCNA biopsy was performed twice and lung cancer was diagnosed by a pathological examination. The MAGE genes were analyzed using RT-nested PCR from tissue samples obtained from the PCNA biopsy of the lesion. We compared the results from the RT-nested PCR and the pathologic diagnosis. We also analyzed the sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value (NPV). RESULTS Of the 53 patients, 39 were diagnosed with lung cancer. Six patients had tuberculosis and 8 were confirmed with chronic inflammation or benign lesion. Based on the RT-nested PCR examination, 41 of 53 patients were positive for the MAGE gene: 34 of 39 patients had lung cancer; 5 of 6 patients had tuberculosis; and 2 of 8 patients had chronic inflammation or benign lesion. The sensitivity, specificity, accuracy, PPV and NPV were 83%, 58%, 77%, 87% and 55%, respectively. CONCLUSION MAGE gene analysis by RT-nested PCR may be a useful method for the diagnosis of lung cancer, but it is still limited in patients with tuberculosis.

Detection of disseminated tumour cells in mediastinoscopic lymph node biopsies and endobronchial ultrasonography-guided transbronchial needle aspiration in patients with suspected lung cancer. Lung Cancer 2009; 68:383-8.

Abstract
PURPOSE Ultrasound-guided transbronchial needle aspiration of mediastinal lymph nodes (EBUS-TBNA) is apparently more accurate for cancer diagnosis than standard transbronchial needle aspiration (TBNA), but it is less sensitive than mediastinoscopy. The detection of disseminated tumour cells in transbronchial needle aspiration and mediastinoscopic biopsies could improve staging and might be helpful concerning indications for neoadjuvant regimen. The goal of this study was to develop a quantitative method for the detection of disseminated tumour cells (DTCs) in lymph node samples from patients with suspected lung cancer. PATIENTS AND METHODS We compared in a prospective trail EBUS-TBNA (n=58 patients, 86 samples) and mediastinoscopy (n=22 patients, 37 samples) in two largely independent cohorts of lung cancer patients. Eleven patients, 14 samples were analysed using both methods. Patients without evidence of malignant disease were available as controls for EBUS-TBNA (n=20 patients, 28 samples) and mediastinoscopy (n=6 patients, 8 samples). Real-time quantitative mRNA analysis was performed for the cytokeratin 19 (CK19) and MAGE-A genes (MAGE-A 1-6, MAGE-A12) as markers, using a LightCycler 480 instrument. RESULTS CK19 mRNA expression in EBUS-TBNA samples was detected in 84/86 (98%) and in 28/28 control samples (100%). After mediastinoscopy 16/37 (43%) samples of lung cancer patients were CK19 mRNA positive while controls showed no CK19 mRNA expression (0/8). MAGE-A expression was detectable in 42/86 (49%) EBUS-TBNA samples and in 13/37 (35%) mediastinoscopy samples. MAGE-A expression was detected in EBUS-TBNA controls in 3/28 (11%) and 1/8 (12%) mediastinoscopy controls. High MAGE-A expression correlated with increased tumour stage. CONCLUSION Since CK19 expression was detected in all EBUS-TBNA samples from the control patients, but not in mediastinoscopy samples, we conclude that CK19 is not suitable as a marker for disseminated tumour cells in samples attained by EBUS-TBNA. One possible explanation is a contamination with epithelial cells from the bronchial tubes. MAGE-A genes are promising markers for disseminated tumour cells in lymph nodes in patients with suspected lung cancer which merit further investigation.

Abstract
Allogeneic mixed lymphocyte tumor cell cultures (MLTCs) were established using lymphocytes from non-small-cell lung cancer (NSCLC) patient UKY-53 and HLA-A2+ NSCLC tumor cells (UKY-29). The tumor cells expressed the lymphocyte costimulatory molecule CD80 (UKY29.7). Cytolytic activity showed the cytotoxic T-lymphocytes (CTL) lysed UKY-29, but not K562 or Daudi. The CTL also lysed: HLA-A2+ and -A24+ tumor cell lines from a number of tumor histologies. The CTL also lysed Epstein Barr virus transformed (EBV) B-cells, UKY-29EBV, autologous to the stimulating cell line, UKY29TC. These data suggested the presence of both tumor-specific and allogeneic reactivities in the bulk CTL population. Subsequent cDNA cloning analysis and sequencing demonstrated that the bulk CTL population was recognizing: (i) allogeneic target HLA-CW3, and two minor histocompatibility antigens; (ii) guanine nucleotide-binding protein, G(S) (GNAS), and (iii) inositol myophosphatase (IMPA). All three antigens, we believe, were restricted by HLA-A2. Whereas the system described was initially intended to identify tumor-associated antigens recognized by CTL, the nature of the allogeneic system provides a unique opportunity for the identification of epitopes that confer both allo and minor antigen recognition.

Abstract
The expression of the melanoma-associated antigen (MAGE) genes consists of variables in all tumor types, such as lung cancer, which are relevant to be silent in all normal tissues except germ cells. They are considered as tumor-specific antigens, and are ideal targets for cancer immunotherapy. A complete MAGE genes differential expression profile analysis of lung cancer can provide this study not only various target genes for immunotherapy, but also valuable markers for further diagnosis and prognosis. This research has constructed a membrane array, which was consisted 32 MAGE genes, to detect whether the differential expression profile occurred in 52 pairs of non-small-cell lung cancer (NSCLC) samples. Nearly 32 MAGE genes have been differential expressed in NSCLC except MAGE-B1 and -E2. MAGE-B, -C, -D, and subgroup -B6, -D4 have showed prominences in lung adenocarcinoma. High-frequent expression of MAGE-D, and subgroup -A2, -D2 has also been discovered in non-metastasis group (p<0.05). However, there is no significant difference of MAGE genes differential expression shown among different primary tumor (T), nodal involvement (N) and overall stages. Several MAGE subgroup genes, such as MAGE-A5, -A7, -A8, -A9, -A11, -B3, -B4, -B10, -D2, -D3, -F1, -G1, -H1, and -L2, have been first discovered to show differential expression in NSCLC. Although the small size of the sample may limit the diagnostic and prognostic value of MAGE genes, the function of the membrane array can provide this study a high-throughput method to detect the whole MAGE genes differential expression profile.

Abstract
A variety of melanoma antigen A (MAGE-A) genes are commonly detected in non-small cell lung cancers. Their biological function is not well characterized but may involve the regulation of apoptosis and cell cycle progression. We hypothesized that MAGE-A4 is involved in the regulation of apoptosis. To investigate this, expression of MAGE-A was evaluated. MAGE-A4 was expressed in 48% of non-small cell lung carcinomas. Ninety percent of lung carcinomas expressing MAGE-A4 were classified as squamous cell carcinomas and 10% were adenocarcinomas. Tumor-free surrounding lung tissue was negative for MAGE-A4. A molecular clone of MAGE-A4 derived from human lung cancer was stably expressed in human embryonic kidney cells (293 cells) to evaluate effects on cell death. Overexpression of MAGE-A4 increased apoptosis as measured by the apoptotic index (P < 0.0001) and caspase-3 activity (P < 0.002). Exposure to 25 micromol/L etoposide, a chemotherapeutic agent, increased the apoptotic effect (P < 0.0001). Furthermore, we show that MAGE-A4 silencing using a small interfering RNA approach results in decreased caspase-3 activity in the squamous cell lung cancer cell line H1703 by 58% (P = 0.0027) and by 24% (P = 0.028) in 293/MAGE-A4 cells. These findings suggest that MAGE-A4 expression may promote tumor cell death, sensitize malignancies to apoptotic stimuli, such as chemotherapeutic agents, and therefore may represent a tumor suppressor protein.

Abstract
Aberrant methylation of CpG islands is an important pathway for regulation of gene expression. Recent data suggest that epigenetic abnormalities may occur very early in lung carcinogenesis. We studied the promoters of the four genes, HOX A9, p16(INK4a) (p16), MAGE A1 and MAGE B2 by methylation-specific PCR in matched normal tissue, tumour, and cytological negative sputum samples obtained from 22 patients with non-small cell lung cancer (NSCLC). We further report methylation abnormalities in sputum samples from 56 smokers with differential cytology readouts (negative, inflammatory changes, suspicious, and cancer). Our method was successfully performed on formalin-fixed and paraffin-embedded (FFPE) samples, and was fit to study only few cells obtained by a convenient non-invasive sputum collection and handling. The promoters of MAGE A1 and MAGE B2 had abnormal methylation patterns in, respectively, 50% and 41% of the cytologically negative sputum samples from NSCLC patients, whereas methylation abnormalities of p16 was observed in 27% of negative sputum samples. Interestingly, 95.5% (21 of 22) of the cytologically negative sputum samples from NSCLC patients had abnormal methylation in at least one of the four genes indicating a high sensitivity of this marker system. Moreover, a higher frequency of methylation abnormalities was observed in sputum samples from smokers with high cytological grade compared to low cytological grade. We conclude that the identification of abnormal gene methylation of a limited number of markers in FFPE sputum samples is feasible and may be investigated as a potential system for population-based screening of early stages of lung cancer.

Abstract
In a phase I/II study, patients with solid metastatic MAGE-3-positive tumors, mainly melanoma, were vaccinated with recombinant MAGE-3 protein combined with the immunologic adjuvant AS02B comprised of MPL and QS21 in an oil-in-water emulsion. The recombinant MAGE-3 protein was made up of a partial sequence of the protein D (ProtD) antigen of Haemophilus influenzae fused to the MAGE-3 sequence. The vaccine was given intramuscularly at 3-week intervals. Patients whose tumors stabilized or regressed after 4 vaccinations received 2 additional vaccinations at 6-week intervals. MAGE-3 and ProtD antibody and cellular immune responses were monitored after vaccination. Ninety-six percent (23/24) of the patients vaccinated with MAGE-3 protein in AS02B adjuvant elicited a significant anti-MAGE-3 IgG antibody response after 4 vaccinations, and all developed anti-ProtD IgG antibodies. For the detection of T-cell activity, total peripheral blood mononuclear cells were restimulated in vitro with MAGE-3- or ProtD-loaded autologous mature dendritic cells. In 30% of the evaluable patients vaccinated with the adjuvanted recombinant protein, IFNgamma production was increased in response to MAGE-3, and 2 patients (14% of evaluable patients) had a concomitant increase in IL-5 production. In 37% and 43% of the patients, respectively, IFNgamma or IL-5 production was increased in response to ProtD. It is concluded that vaccination of advanced cancer patients with MAGE-3 self-antigen in AS02B adjuvant is able to elicit MAGE-3-specific antibody and a T-cell response.

Abstract
MAGE-3 is the most commonly expressed cancer testis Ag and thus represents a prime target for cancer vaccines, despite infrequent natural occurrence of MAGE-3-specific immune responses in vivo. We report in this study the successful induction of Ab, CD8(+), and CD4(+) T cells in nonsmall cell lung cancer patients vaccinated with MAGE-3 recombinant protein. Two cohorts were analyzed: one receiving MAGE-3 protein alone, and one receiving MAGE-3 protein with adjuvant AS02B. Of nine patients in the first cohort, three developed marginal Ab titers and another one had a CD8(+) T cell response to HLA-A2-restricted peptide MAGE-3 271-279. In contrast, of eight patients from the second cohort vaccinated with MAGE-3 protein and adjuvant, seven developed high-titered Abs to MAGE-3, and four had a strong concomitant CD4(+) T cell response to HLA-DP4-restricted peptide 243-258. One patient simultaneously developed CD8(+) T cells to HLA-A1-restricted peptide 168-176. The novel monitoring methodology used in this MAGE-3 study establishes that protein vaccination induces clear CD4(+) T cell responses that correlate with Ab production. This development provides the framework for further evaluating integrated immune responses in vaccine settings and for optimizing these responses for clinical benefit.

Abstract
BACKGROUND Since the mortality of lung cancer patients remains very high, the development of a sensitive detection method remains an urgent task. The authors have designed common melanoma antigen gene (MAGE) primers that enable the detection of MAGE A1 to A6 subtypes simultaneously. These primers were applied to the detection of lung cancer using sputum specimens. METHODS The study involved, 53 cancer patients and three non-cancer groups (193 healthy people, 235 lung cancer screening group and 140 patients with benign lung diseases) were investigated. One hundred and thirty-six respiratory specimens (55 random sputa, 33 induced sputa, 40 broncho-alveolar lavage (BAL) fluids, and 8 pleural fluids) from different lung cancer patients were blindly tested. The MAGE assay was performed by RT-nested PCR, and the results obtained from sputum were compared with those obtained by telomerase assay and conventional cytology. RESULTS In the sputum of the non-cancer groups, the positive rates were less than 2.1%, while the detection rates were 83.3% in the cancer tissues and 54.3% in the sputa of lung cancer patients. For the random sputum samples of lung cancer patients, the detection rate was 47.5%, but in the induced sputum, BAL and pleural fluids, the detection rate was up to over 70.0%. The MAGE assay produced a higher detection rate than the telomerase assay and conventional cytology. CONCLUSIONS MAGE A1-6 RT-PCR, which showed high sensitivity and specificity, provides an effective means for the lung cancer detection in sputum.

Abstract
Melanoma antigen (MAGE)-encoding genes are expressed in various tumour types via demethylation of their promoter CpG islands, which are silent in all non-neoplastic tissues except for the testis and placenta. The clinicopathological significance of demethylation of MAGE genes in gastric carcinoma is not known. We investigated the promoter methylation status of MAGE-A1 and -A3 in 10 gastric cancer cell lines and in surgical specimens from 84 gastric cancer patients by methylation-specific PCR (MSP). Expression of MAGE-A1 and -A3 in the 10 gastric cancer cell lines was also investigated by RT–PCR. Any correlation between the methylation status of the MAGE promoters and clinicopathological characteristics of the gastric cancer patients was then assessed. Eight of the 10 gastric cancer cell lines showed demethylation of both MAGE-A1 and -A3, and the remaining two cell lines did either of MAGE-A1 or -A3. Expression of MAGE-A1 and -A3 was confirmed in seven and nine of the 10 gastric cancer cell lines, respectively. The MAGE-A1 and -A3 promoters were demethylated in 29% (25 out of 84) and 66% (56 out of 84) of the gastric tumour specimens, respectively. Demethylation of both MAGE-A1 and -A3 promoters (n=22) was found more frequently in gastric cancer patients in advanced clinical stages (P=0.0035), and these patients also exhibited a higher incidence of lymph node metastasis (P=0.0007) compared to those patients without demethylation (n=25). Furthermore, demethylation patients tended to have a worse prognosis, although this difference was not statistically significant (P=0.183). Demethylation of MAGE-A1 and -A3 occurs during progressive stages of gastric cancer, and may be associated with aggressive biological behaviour of gastric cancer.

Abstract
An emerging body of literature indicates that reversible alterations in chromatin structure modulate gene expression during malignant transformation. Chromatin structure is regulated in part by DNA methylation and histone acetylation; these independent yet highly interrelated epigenetic processes are influenced by a variety of signal transduction pathways. The present review highlights recent advances regarding cancer epigenetics, focusing on the potential utilization of chromatin remodeling agents to induce apoptosis and enhance the immunogenicity of thoracic malignancies.

Abstract
BACKGROUND Lung carcinoma represents the most frequent cause of cancer death worldwide because of tumor metastases. The objective of the current study was to analyze the immunologic response during the progress of lung carcinoma metastasis. METHODS The authors established two tumor cell lines that were derived from primary and metastatic lesions in a patient with lung carcinoma (Patient G603). One cell line (G603L) was established from the primary lesion, and the other cell line (G603AD) was established from a metastatic lesion in the right adrenal gland 7 months after the patient underwent surgery for the primary lesion. Autologous regional lymph node lymphocytes were stimulated with CD80-transfected G603L cells, then cytotoxic T lymphocytes (CTLs) were induced against both lung carcinoma cell lines. RESULTS Both G603L cells and G603AD cells expressed Class I human leukocyte antigen, intracellular cell adhesion molecule 1, and lymphocyte-associated antigen type 3 (LFA-3), but not Fas or Fas ligand on their surfaces. By stimulation with CD80-transfected G603L cells, 2 CTL clones (H2/17 and H2/36) were established from the bulk CTLs. CTL clone H2/17 lysed G603L cells but not G603AD cells, suggesting that the antigen recognized by CTL clone H2/17 was abrogated during the process of metastasis. In contrast, CTL clone H2/36 lysed both G603L cells and G603AD cells, indicating that the antigen recognized by CTL clone H2/36 was maintained in the tumor cells throughout tumor progression. CONCLUSIONS The results demonstrated the possibility that some tumor-associated antigens may be abrogated during the process of metastasis, although others are maintained. The identification of these antigens will lead to a better understanding of their immunologic role during disease progression in patients with lung carcinoma.

Abstract
A number of cancer vaccine and gene therapy approaches are being evaluated in patients with lung cancer. Cancer vaccine strategies include GM-CSF gene-modified cancer cells, liposomal MUC1 peptide, anti-idiotype antibody targeting GD3, Mage-3 peptide, and mutant p53 pulsed dendritic cells among others. Preliminary human trials have demonstrated immune responses as well as tumor regression in late stage disease. The largest human gene therapy experience in lung cancer is with intratumoral gene replacement therapy, predominantly with p53, but such approaches are limited to locoregional disease control. Earlier stage gene therapy programs targeting the immune system or tumor vasculature hold promise as systemic therapies for treatment of advanced, disseminated disease.

Abstract
The expression of melanoma antigen gene (MAGE), coding for tumor antigens recognized by cytotoxic T cell, is highly specific to cancer cells, but their use in the detection of a few cancer cells by reverse transcription-polymerase chain reaction (RT-PCR) has been limited by the low frequency of expression of individual MAGE genes. In order to increase MAGE detection rate in RT-PCR assay, here, we designed multiple MAGEs recognizing primers (MMRPs) that can bind to the sequences of cDNA of MAGE-1, -2, -3, -4a, -4b, -5a, -5b and-6 (MAGE 1-6) together. The nested RT-PCR assay using MMRPs, MAGE 1-6 assay, detected MAGE messages of 1 to 5 SNU484 cells in a background of 10(7) SNU638 cells. MAGE detection rate of MAGE 1-6 assay in cancers was higher than that of nested RT-PCR that detects single MAGE gene expression. The expressions of MAGE genes was detected by MAGE 1-6 assay in 70.4% (19/27) of head and neck cancer tissues, 91.7% (11/12) of breast cancer tissues, 75% (9/12) of lung cancer tissues. However, they were not detected in 18 benign lesions and 20 normal head and neck tissues and 30 blood samples from healthy donor. In conclusions, MAGE 1-6 assay can detect any cancer cells that express at least one of eight MAGE subtype genes, and this method may be very useful for the diagnosis of MAGE-expressing cancers.

Abstract
MAGE-A1, -A2, -A3, -A4, -A6, -A10, and -A12 are expressed in a significant proportion of primary and metastatic tumors of various histological types and are targets of tumor Ag-specific CTL. Individual MAGE-A expression varies from one tumor type to the other but, overall, the large majority of tumors expresses at least one MAGE-A Ag. Therefore, targeting epitopes shared by all MAGE-A Ags would be of interest in immunotherapy against a broad spectrum of cancers. In the present study, we describe a heteroclitic MAGE-A peptide (p248V9) that induces CTL in vivo in HLA-A*0201 transgenic HHD mice and in vitro in healthy donors. These CTL are able to recognize two low HLA-A*0201 affinity peptides differing at their C-terminal position and derived from MAGE-A2, -A3, -A4, -A6, -A10, and -A12 (p248G9) and MAGE-A1 (p248D9). Interestingly, p248V9-specific CTL respond to endogenous MAGE-A1, -A2, -A3, -A4, -A6, -A10, and -A12 in an HLA-A*0201-restricted manner and recognize human HLA-A*0201(+)MAGE-A(+) tumor cells of various histological origin. Therefore, this heteroclitic peptide may be considered as a potent candidate for a broad-spectrum tumor vaccination.

[PMID: 11753648 DOI: 10.1038/sj.onc.1204939] [Citation(s) in RCA: 31] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2001] [Revised: 08/15/2001] [Accepted: 08/30/2001] [Indexed: 11/09/2022]
Abstract
Using a combination of cDNA subtraction and microarray analysis, we report here the identification and characterization of L552S, an over-expressed, alternatively spliced isoform of XAGE-1 in lung adenocarcinoma. Real-time RT-PCR analysis shows that L552S is expressed at levels greater than 10-fold in 12 of 25 lung adenocarcinoma tumors compared with the highest expression level found in all normal tissues tested. L552S is expressed in both early and late stages of lung adenocarcinoma, but it was not detected in large cell carcinoma, small cell carcinoma, or atypical lung neuroendocrine carcinoid. The full-length cDNA for L552S comprises 770 bp and encodes a polypeptide of 160 amino acids. C-terminal 94 amino acids of L552S are identical to a cancer testis antigen, XAGE-1, found in Ewing's sarcoma. Genomic sequence analysis has revealed that L552S and XAGE-1 are alternatively spliced isoforms, and expression of both L552S and XAGE-1 isoforms are present in lung adenocarcinoma. Immunohistochemistry analysis using affinity purified L552S polyclonal antibodies demonstrated specific nuclear staining in 10 of 12 lung adenocarcinoma samples. Furthermore, antibody responses to recombinant L552S protein were observed in seven of 17 lung pleural effusion fluids of lung cancer patients. These results strongly imply that L552S protein is immunogenic and suggest that it might have use as a vaccine target for lung cancer.
