Abstract
Retinoblastoma is the most common intraocular tumor in children. Patients can be cured by enucleation, but it can lead to vision loss. Chemotherapy is the main method of treatment for RB currently. Unfortunately, chemoresistant and tumor metastasis often happen, resulting in a relatively poor prognosis. Therefore, immunotherapy becomes one of the optimal choices. Targeting not only tumor cells but also the active tumor microenvironment is a novel strategy for RB treatment. Here, we conclude several potential targets for RB immunotherapy, including gangliosides GD2, PD-1 and PD-L1, B7H3, EpCAM and SYK. We also review the techniques for CART, bispecific antibodies and genetically modified Dendritic cells according to the characteristics of different targets and discuss the feasibility of immunotherapy with different targets.

Abstract
Over the past two decades, quantitative proteomics has emerged as an important tool for deciphering the complex molecular events involved in cancers. The number of references involving studies on the cancer metastatic process has doubled since 2010, while the last 5 years have seen the development of novel technologies combining deep proteome coverage capabilities with quantitative consistency and accuracy. To highlight key findings within this huge amount of information, the present review identified a list of tumor invasive biomarkers based on both the literature and data collected on a biocollection of experimental cell lines, tumor models of increasing invasiveness and tumor samples from patients with colorectal or breast cancer. Crossing these different data sources led to 76 proteins of interest out of 1,245 mentioned in the literature. Information on these proteins can potentially be translated into clinical prospects, since they represent potential targets for the development and evaluation of innovative therapies, alone or in combination. Herein, a systematical review of the biology of each of these proteins, including their specific subcellular/extracellular or multiple localizations is presented. Finally, as an important advantage of quantitative proteomics is the ability to provide data on all these molecules simultaneously in cell pellets, body fluids or paraffin‑embedded sections of tumors/invaded tissues, the significance of some of their interconnections is discussed.

Abstract
Human leukocyte antigen class I (HLA-I) molecules are transmembrane glycoproteins that have been reported to be down-regulated in multiple types of human malignancies, including clear cell renal cell carcinoma (CCRCC). However, only one study has investigated its prognostic value in CCRCC. In the present study, HLA-I protein expression was analyzed in 120 archived, paraffin-embedded CCRCC samples and 10 adjacent normal tissues using immunohistochemistry. The correlation between HLA-I expression and clinicopathological factors was evaluated by the χ(2) test. Patients' overall survival was analyzed by the Kaplan-Meier method. HLA-I down-regulation was observed in 38.3% (46/120) of renal tumor samples, but only in 10% (1/10) of adjacent normal tissues. Statistical analysis showed a significant correlation of HLA-I expression with TNM stage, lymph node metastasis, and Fuhrman grade. Patients with tumors displaying down-regulation of HLA-I showed significantly shorter overall survival (P=0.021, log-rank test). More importantly, multivariate analysis indicated that down-regulation of HLA-I was an independent prognostic factor for CCRCC patients (P=0.033). Overall, our data suggest that HLA-I down-regulation is associated with tumor progression and a poor prognosis in CCRCC patients, and emphasize the importance of HLA-I in natural and therapeutic immune surveillance of patients with CCRCC.

Abstract
The transitional endoplasmic reticulum (tER) is composed of both rough and smooth ER membranes and thus participates in functions attributed to both these two subcellular compartments. In this paper we have compared the protein composition of tER isolated from dissected liver tumor nodules of aflatoxin B1-treated rats with that of tER from control liver. Tandem mass spectrometry (MS), peptide counts and immunoblot validation were used to identify and determine the relative expression level of proteins. Inhibitors of apoptosis (i.e. PGRMC1, tripeptidyl peptidase II), proteins involved in ribosome biogenesis (i.e. nucleophosmin, nucleolin), proteins involved in translation (i.e. eEF-2, and subunits of eIF-3), proteins involved in ubiquitin metabolism (i.e. proteasome subunits, USP10) and proteins involved in membrane traffic (i.e. SEC13-like 1, SEC23B, dynactin 1) were found overexpressed in tumor tER. Transcription factors (i.e. Pur-beta, BTF3) and molecular targets for C-Myc and NF-kappa B were observed overexpressed in tER from tumor nodules. Down-regulated proteins included cytochrome P450 proteins and enzymes involved in fatty acid metabolism and in steroid metabolism. Unexpectedly expression of the protein folding machinery (i.e. calreticulin) and proteins of the MHC class I peptide-loading complex did not change. Proteins of unknown function were detected in association with the tER and the novel proteins showing differential expression are potential new tumor markers. In many cases differential expression of proteins in tumor tER was comparable to that of corresponding genes reported in the Oncomine human database. Thus the molecular profile of tumor tER is different and this may confer survival advantage to tumor cells in cancer.

Abstract
Defects in the expression and/or function of the human leukocyte antigen (HLA) class I antigen-processing machinery (APM) components are found in many tumor types. These abnormalities may have a negative impact on the interactions of tumor cells with host's immune system and on the outcome of T cell-based immunotherapy. To the best of our knowledge, no information is available about APM component expression and functional characteristics in human medulloblastoma cells (Mb). Therefore, in the present study, we have initially compared the expression of APM components in Mb, an embryonal pediatric brain tumor with a poor prognosis, with that in noninfiltrating astrocytic pediatric tumors, a group of differentiated brain malignancies with favorable prognosis. LMP2, LMP7, calnexin, beta2-microglobulin-free heavy chain (HC) and beta2-microglobulin were down-regulated or undetectable in Mb lesions, but not in astrocytic tumors or normal fetal cerebellum. Two Mb cell lines (DAOI and D283) displayed similar but not superimposable defects in APM component expression as compared with primary tumors. To assess the functional implications of HLA class I APM component down-regulation in Mb cell lines, we tested their recognition by HLA class I antigen-restricted, tumor antigen (TA)-specific CTL, generated by stimulations with dendritic cells that had been transfected with Mb mRNA. The Mb cell lines were lysed by TA-specific CTL in a HLA-restricted manner. Thus, defective expression of HLA class I-related APM components in Mb cells does not impair their ability to present TA to TA-specific CTL. In conclusion, these results can contribute to optimize T cell-based immunotherapeutic strategies for Mb treatment.

Abstract
PURPOSE Human leukocyte antigen (HLA) mediates interactions of tumor cells with cytotoxic T lymphocytes (CTLs) and natural killer (NK) cells. Retinoblastoma (RB) is the most common intraocular malignant tumor in childhood and is characterized by direct spread to the optic nerve and orbit as well as hematogenous and lymphatic spread. Earlier, we observed that invasive RB showed reduced HLA, which could contribute to its escape from the immune system. Little is known about the role of the nonclassical HLA molecule, HLA-G, in RB and its role in tumor escape mechanisms in RB. METHODS Forty archival paraffin-embedded RB tumors were analyzed for the expression of HLA-G by immunohistochemistry using a monoclonal antibody; fresh tumor samples were also subjected to Western blot analysis. There were 22 tumors with no invasion and 18 with invasion of the choroid/optic nerve. Immunoanalysis was performed based on the International Histocompatibility Working Group Project Description. RESULTS HLA-G was negative in the non-neoplastic retina, reduced in 22/22 tumors with no invasion, and positive in 15/18 with invasion. The immunohistochemistry results were confirmed by Western blot analysis. The difference in expression between the two groups was significant ( p < 0.001). There was no correlation of HLA-G expression with differentiation of the tumors. CONCLUSION Increased expression of HLA-G was observed in invasive RB. This preliminary observation deserves further investigation and may shed more light on the immune escape mechanisms of this tumor and thus enable novel therapeutic strategies.

Abstract
We examine the immunoreactivity of the non-receptor tyrosine kinase, c-Src kinase and its downstream molecule, signal transducer and activator of transcription 3 (pStat3) in retinoblastoma (RB), and correlation with invasiveness and differentiation. Tumor samples from 40 patients with RB were available for the study. There were 18 tumors in group 1 (non-invasive) and 22 tumors in group 2 (invasive). The immunoreactivity of c-Src kinase and pStat3 was compared in the two groups of tumors. Group 1 (non-invasive) RB showed intermediate c-Src kinase immunoreactivity (Allred score 4-5) in 14/18 tumors and low immunoreactivity (Allred score 2-3) in 4/18 tumors. pStat3 was intermediate (Allred score 4-5) in 6/18 tumors and negative (Allred score 0) in 12/18 tumors. Group 2 (invasive) RB showed high c-Src kinase immunoreactivity (Allred score 6-8) in 22/22 tumors and high pStat3 (Allred score 6-8) in 19/22 tumors. The expression of c-Src kinase (P<0.001) and pStat3 (P<0.001) was significantly higher in group 2 RB. Src kinase expression (P<0.05) and pStat3 expression (P<0.05) was higher in the poorly differentiated tumors compared to moderately- and well-differentiated tumors. The increased expression of c-Src kinase and pStat3 expression could play a role in the invasiveness of group 2 tumors. Further characterization of the pathways involved in the pathogenesis of RB will shed light on fundamental mechanisms of tumorigenesis.

Abstract
BACKGROUND To investigate the potential involvement of the nitric oxide (NO) pathway in retinoblastoma, the authors correlated immunoreactivity for endothelial nitric oxide synthase (eNOS), inducible nitric oxide synthase (iNOS), and nitrotyrosine (NT) with the degree of tumor invasiveness in retinoblastoma. METHODS eNOS, iNOS, and NT reactivity was evaluated by immunohistochemistry in 34 archival retinoblastoma specimens and in a human Y79 retinoblastoma cell line. The tumors were divided into 2 groups: Group A tumors (n = 17 tumors) with no invasion and Group B tumors (n = 17 tumors) with invasion of the choroid, optic nerve, and/or orbit. The expression levels of eNOS, iNOS, and NT were correlated with invasiveness of the tumors. RESULTS In Group A tumors (n = 17 tumors) without invasion, eNOS was positive in 17 of 17 tumors (100%), iNOS was positive in 14 of 17 tumors (82%), and NT was positive in 17 of 17 tumors (100%). In Group B tumors (n = 17 tumors) with invasion, eNOS was positive in 17 of 17 tumors (100%), iNOS was positive in 16 of 17 tumors (94%), and NT was positive in 17 of 17 tumors (100%). The invasive cohort showed significantly higher expression of iNOS (P < 0.0001) and NT (P < 0.020) compared with the noninvasive cohort. Y79 cells also expressed eNOS, iNOS, and NT; and nonneoplastic retina was positive for eNOS, iNOS, and NT. CONCLUSIONS Taken together, the results suggested that retinoblastomas can produce NO. The roles of NO in the biology of retinoblastoma and in the prognosis for patients with retinoblastoma remain to be established.

Abstract
The transporter associated with antigen processing (TAP) is a member of the ATP-binding cassette transporter family that specializes in delivering cytosolic peptides to class I molecules in the endoplasmic reticulum. The TAP is a major target of genetic alteration in tumours and disruption by viral inhibitors. In some species, TAP genes have co-evolved with MHC class I molecules to deliver peptides that are customised for particular alleles. In humans, MHC class I polymorphism determines the level of tapasin-mediated association with TAP and subsequent peptide optimisation within the peptide-loading complex (PLC). MHC class I molecules that still load peptides without complexing to the TAP might be more resistant to viral interference of the PLC and less sensitive to competition for TAP by other class I allotypes.

Abstract
HLA class I antigen defects are frequently found in malignant cells. They appear to play a role in the clinical course of the disease, probably because they provide tumor cells with a mechanism to escape cytotoxic T lymphocyte (CTL) recognition and destruction. Expression of HLA class I antigens, however, is not always associated with the susceptibility of tumor cells to CTL lysis. Many mechanisms may underlie this finding, including the lack of tumor antigen (TA)-derived peptide presentation by a given HLA class I allospecificity, and/or the expression of immunosuppressive molecules such as HLA-G. These findings emphasize the need to develop probes to measure HLA class I allospecificity-TA peptide complex expression in malignant cells. Furthermore, the evaluation of the role of HLA class I antigens in the interaction of malignant cells with host immune cells should take into account the potential interference of tumor-derived immunomodulators.
