BACKGROUND: Exposure to ionizing radiation (IR) often causes severe damage to radiosensitive tissues, which limits the use of radiotherapy in cancer patients. Novel safe and effective radioprotectant is urgently required. It has been reported toll like receptor 2 (TLR2) plays a critical role in radioresistance. In this study, we demonstrated the protective effects of Heat-Killed Mycobacterium tuberculosis (HKMT), a potent TLR2 agonist, against IR. METHODS: Cell survival and apoptosis were determined by CCK-8 assay and Annexin V assay, respectively...

The majority of bladder cancer-associated mortalities are due to transitional cell carcinoma (TCC), which is the most prevalent and chemoresistant malignancy of the bladder. Sperm acrosome associated 5 (SPACA5)/Spaca5 is a sperm acrosome-associated, c-type lysozyme-like protein that has been recently identified, and has been designated as an attractive candidate antigen for cancer testis. In the present study, the expression profile of SPACA5/Spaca5 was analyzed in spermatogenesis and TCC of the bladder using diverse molecular and cellular biology methods...

The aim of this study was to identify and compare cancer sites whose incidence is influenced by social deprivation. The study population comprised 189 144 cases of cancer diagnosed between 2006 and 2009, recorded in member registries of the French Network of Cancer Registries. Social environment was assessed at an aggregate level using the European Deprivation Index. The association between incidence and socioeconomic status was assessed by a geographical Bayesian Poisson model enabling a reduction of the overall variability and smoothing of the relative risks by sharing information provided by multiple geographic units...

Overexpression of mutant p53 is a common finding in most cancers but testicular tumours accumulate wild-type p53 (wtp53). In contrast to the accepted concept that p53 homozygous mutant mice do not accumulate mutant p53 in normal cells, our study on a mutant p53 mouse model of Li-Fraumeni syndrome harbouring the hot-spot p53R172H mutation described an elevated level of mutant p53 in non-cancerous mouse tissues. Here we use detailed immunohistochemical analysis to document the expression of p53R172H in mouse testis...

Although mutations may represent attractive targets for immunotherapy, direct identification of mutated peptide ligands isolated from human leucocyte antigens (HLA) on the surface of native tumour tissue has so far not been successful. Using advanced mass spectrometry (MS) analysis, we survey the melanoma-associated immunopeptidome to a depth of 95,500 patient-presented peptides. We thereby discover a large spectrum of attractive target antigen candidates including cancer testis antigens and phosphopeptides...

OBJECTIVES: As the best characterised cancer/testis antigen family members, melanoma-associated antigens (MAGE) have been reported to be expressed in various malignant tumours. However, the expression pattern of MAGE-A family in lung adenocarcinoma (LAC) specimens and their prognostic and therapeutic significance for patients with LAC is still unclear. MATERIALS AND METHODS: Tissue microarray-based immunohistochemistry analysis was used to examine the expression of MAGE-A family members (including MAGE-A1, A2, A3, A4, A6, A10, A11 and A12) in 105 paired LAC specimens and the corresponding pericarcinoma specimens...

STUDY QUESTION: What are the primary causes of severe male factor infertility? SUMMARY ANSWER: Although 40% of all patients showed primary causes of infertility, which could be subdivided into three groups based on the severity of their effect, ~75% of oligozoospermia cases remained idiopathic. WHAT IS KNOWN ALREADY: There are few large-scale epidemiological studies analyzing the causes of male factor infertility. STUDY DESIGN, SIZE, DURATION: A prospective clinical-epidemiological study was conducted at the Andrology Centre, Tartu University Hospital between 2005 and 2013, recruiting male partners of couples failing to conceive a child for over ≥12 months...

BACKGROUND: Breast cancer is one of the most common malignancies with increasing incidences every year and a leading cause of death among women. Although early stage breast cancer can be effectively treated, there are limited numbers of treatment options available for patients with advanced and metastatic disease. The novel breast cancer associated antigen NY-BR-1 was identified by SEREX analysis and is expressed in the majority (>70%) of breast tumors as well as metastases, in normal breast tissue, in testis and occasionally in prostate tissue...

INTRODUCTION: Decreased expression of highly immunogenic cancer-testis antigens (CTA) might help tumor to achieve low immunogenicity, escape immune surveillance and grow unimpeded. Our aim was to evaluate CTA expression in tumor and normal tissues and to investigate possible means of improving the immune response in a murine prostate cancer (CaP) model by using the combination of epigenetic modifier 5-azacitidine (5-AzaC) and immunomodulator lenalidomide. No study to date has examined the effect of this combination on the prostate cancer or its impact on antigen-presenting cells (APC)...

BACKGROUND: Nonseminomatous germ cell tumor of the testis (NSGCT) is largely curable. However, a small group of patients develop refractory disease. We investigated the hypothesis that intratumoral heterogeneity contributes to the emergence of chemoresistance and the development of refractory tumor subtypes. RESULTS: Our institution's records for January 2000 through December 2010 included 275 patients whose primary tumor showed pure embryonal carcinoma (pure E); mixed embryonal carcinoma, yolk sac tumor, and teratoma (EYT); or mixed embryonal carcinoma, yolk sac tumor, seminoma, and teratoma (EYST)...

Multiple myeloma is a plasma cell tumor that homes to and expands in the bone marrow and that, despite the new available drugs, remains incurable. Extramedullary plasmacytoma is a not frequent manifestation during the natural history of multiple myeloma and is frequently associated with plasma cell bone marrow infiltration. The most common locations for an EMP include the gastrointestinal tract, pleura, testis, skin, peritoneum, liver, endocrine glands, and lymph nodes. Primary involvement of the gallbladder fossa is exceedingly rare...

Melanoma metastases can be categorized by gene expression for the presence of a T-cell-inflamed tumor microenvironment, which correlates with clinical efficacy of immunotherapies. T cells frequently recognize mutational antigens corresponding to nonsynonymous somatic mutations (NSSMs), and in some cases shared differentiation or cancer-testis antigens. Therapies are being pursued to trigger immune infiltration into non-T-cell-inflamed tumors in the hope of rendering them immunotherapy responsive. However, whether those tumors express antigens capable of T-cell recognition has not been explored...

BACKGROUND: The purpose of our study was to characterize the causes of death among cancer patients as a function of objectives: (I) calendar year, (II) patient age, and (III) time after diagnosis. PATIENTS AND METHODS: US death certificate data in SEER Stat 8.2.1 were used to categorize cancer patient death as being due to index-cancer, non-index-cancer, and non-cancer cause from 1973 to 2012. In addition, data were characterized with standardized mortality ratios (SMRs), which provide the relative risk of death compared to all persons...

Cancer related to hereditary syndromes corresponds to approximately 5-10% of all tumors. Among those from the genitourinary system, many tumors had been identified to be related to genetic syndromes in the last years with the advent of new molecular genetic tests. New entities were described or better characterized, especially in kidney cancer such as hereditary leiomyomatosis renal cell carcinoma (HLRCC), succinate de¬hydrogenase kidney cancer (SDH-RCC), and more recently BAP1 germline mutation re¬lated RCC...

Monopolar spindle1 (Mps1, also known as TTK) is the core component of the spindle assembly checkpoint, which functions to ensure proper distribution of chromosomes to daughter cells. Mps1 is hardly detectable in normal organs except the testis and placenta. However, high levels of Mps1 are found in many types of human malignancies, including glioblastoma, thyroid carcinoma, breast cancer, and other cancers. Several Mps1 inhibitors can inhibit the proliferation of cancer cells and exhibit demonstrable survival benefits...

Stathmin-1 (STMN1) is a microtubule-destabilizing protein which is overexpressed in cancer. Its overexpression is associated with poor prognosis and also serves as a predictive marker to taxane therapy. We have developed a proprietary bi-functional shRNA (bi-shRNA) platform to execute RNA interference (RNAi)-mediated gene silencing and a liposome-carrier complex to systemically deliver the pbi-shRNA plasmids. In vitro and in vivo testing demonstrated efficacy and specificity of pbi-shRNA plasmid in targeting STMN1 (Phadke et al...

PURPOSE: Exposure to asbestos is thought to cause the large majority of pleural mesotheliomas in the USA. It is unknown whether asbestos exposure plays a role in the etiology of rarer forms of mesothelioma, e.g., those located in the pericardium or in the tunica vaginalis of the testis. In order to address this question, we sought to determine whether geographic patterns of incidence of these mesotheliomas have paralleled those of pleural mesotheliomas. METHODS: We used age-adjusted incidence data from the nine populations served by the National Cancer Institute's Surveillance, Epidemiology, and End Results program during 1973-2011...
