We conducted a SNP-based genome-wide association study (GWAS) focused on the high-risk subset of neuroblastoma. As our previous unbiased GWAS showed strong association of common 6p22 SNP alleles with aggressive neuroblastoma, we restricted our analysis here to 397 high-risk cases compared to 2,043 controls. We detected new significant association of six SNPs at 2q35 within the BARD1 locus (P(allelic) = 2.35 x 10(-9)-2.25 x 10(-8)). We confirmed each SNP association in a second series of 189 high-risk cases and 1,178 controls (P(allelic) = 7.90 x 10(-7)-2.77 x 10(-4)). We also tested the two most significant SNPs (rs6435862, rs3768716) in two additional independent high-risk neuroblastoma case series, yielding combined allelic odds ratios of 1.68 each (P = 8.65 x 10(-18) and 2.74 x 10(-16), respectively). We also found significant association with known BARD1 nonsynonymous SNPs. These data show that common variation in BARD1 contributes to the etiology of the aggressive and most clinically relevant subset of human neuroblastoma.

    • "Familial studies have identified genes that drive neuroblastoma, such as ALK (Janoueix-Lerosey et al., 2008; Mossé et al., 2008) and PHOX2B (Mosse et al., 2004; Trochet et al., 2004), in a subset of human cases. Conversely, high-powered genome-wide association studies (Capasso et al., 2009; Diskin et al., 2012; Nguyen et al., 2011; Wang et al., 2011) have succeeded in identifying numerous genes that confer a slightly increased risk for the disease . However, the complexity of the disease has confounded the search for druggable pathways. "

    ABSTRACT: The development of targeted therapeutics for neuroblastoma, the third most common tumor in children, has been limited by a poor understanding of growth signaling mechanisms unique to the peripheral nerve precursors from which tumors arise. In this study, we combined genetics with gene-expression analysis in the peripheral sympathetic nervous system to implicate arginase 1 and GABA signaling in tumor formation in vivo. In human neuroblastoma cells, either blockade of ARG1 or benzodiazepine-mediated activation of GABA-A receptors induced apoptosis and inhibited mitogenic signaling through AKT and MAPK. These results suggest that ARG1 and GABA influence both neural development and neuroblastoma and that benzodiazepines in clinical use may have potential applications for neuroblastoma therapy.

    • "In particular, we found that several microRNAs could target the region around SNP rs7585356 (Fig. 2C). MiR- 513c and miR-514b-5p only target the neuroblastoma-associated " A " (Capasso et al., 2009) but not the " C " genotype of the SNP rs7585356. The rs7585356 genotype may also affect the targeting of microRNAs miR-588 and miR-668. "

    ABSTRACT: Long non-coding RNAs (lncRNAs) are ubiquitously expressed RNA molecules of more than 200 nucleotides without substantial ORFs. LncRNAs could act as epigenetic regulators of gene expression affecting transcription, mRNA stability and transport, and translation, although, precise functions have been attributed to only few of them. Competing endogenous RNAs (ceRNAs) represent one recently emerged type of functional lncRNAs that share microRNA recognition sequences with mRNAs and may compete for microRNA binding and thus affect regulation and function of target mRNAs. We studied the epigenetic regulation of the BARD1 gene. The BARD1 protein acts as tumor suppressor with BRCA1. In cancer, mRNAs encoding the tumor suppressor full length BARD1 are often down-regulated while the expression of oncogenic truncated isoforms is boosted. We found that the BARD1 3'UTR is almost 3000 nt long and harbors a large number of microRNA binding elements. In addition we discovered a novel lncRNA, BARD1 9'L, which is transcribed from an alternative promoter in intron 9 of the BARD1 gene and shares part of the 3'UTR with the protein coding BARD1 mRNAs. We demonstrate with the example of two microRNAs, miR-203 and miR-101, that they down-regulate the expression of FL BARD1 and cancer-associated BARD1 mRNAs, and that BARD1 9'L counteracts the effect of miR-203 and miR-101, As BARD1 9'L is abnormally over-expressed in human cancers, we suggest it might be a tumor promoting factor and treatment target.

    • "The single nucleotide polymorphisms (SNPs) from genome-wide association studies (GWAS) were collected. These were associated with either breast cancer [31] [32], colorectal cancer [33] [34], endometrial cancer [35], follicular lymphoma [36], gastric cancer [37], hepatocellular carcinoma [38] [39], Hodgkin's lymphoma [40], lung cancer [41], melanoma [42], nasopharyngeal carcinoma [43], neuroblastoma [44], ovarian cancer [45] [46], pancreatic cancer [47] [48], prostate cancer [49] [50] [51] [52] [53] [54], renal cell carcinoma [55], thyroid cancer [56], or urinary bladder cancer [57]. We hypothesized that these genes, which are located within 100 kb of risk SNPs, are potentially cancer risk genes. "

    ABSTRACT: The testes are where spermatogenesis, the sperm-generating process that is unique to men, occurs. Importantly, human spermatogenesis and tumorigenesis share key similarities. Until now, only a few proteins in the human testis have been identified due to limitations of available technology. In this paper, using an advanced proteomics platform, we have identified 7346 unique proteins within the human testis with a high degree of confidence. Immunohistochemistry data from the Human Protein Atlas database show over 90% (1833/2020) of identified proteins can be detected in the human testis using specific antibodies. To make the data widely available to the scientific community, an online Human Testis Proteome Database (HTPD, was built. Many of the identified human testicular proteins are associated with human infertility, especially human testicular predominantly expressed proteins. We characterized six novel cancer/testis genes (TMPRSS12, TPPP2, PRSS55, DMRT1, PIWIL1, HEMGN), which map to cancer-associated genetic variants positions, in both the cancer and testis tissues using genome-wide analyses. Our results provide a molecular connection between spermatogenesis and tumorigenesis and broaden the range of cancer antigen choice available for immunotherapy.
