Prostate cancer is the second most common cause of male cancer deaths in the United States. However, the full range of prostate cancer genomic alterations is incompletely characterized. Here we present the complete sequence of seven primary human prostate cancers and their paired normal counterparts. Several tumours contained complex chains of balanced (that is, 'copy-neutral') rearrangements that occurred within or adjacent to known cancer genes. Rearrangement breakpoints were enriched near open chromatin, androgen receptor and ERG DNA binding sites in the setting of the ETS gene fusion TMPRSS2-ERG, but inversely correlated with these regions in tumours lacking ETS fusions. This observation suggests a link between chromatin or transcriptional regulation and the genesis of genomic aberrations. Three tumours contained rearrangements that disrupted CADM2, and four harboured events disrupting either PTEN (unbalanced events), a prostate tumour suppressor, or MAGI2 (balanced events), a PTEN interacting protein not previously implicated in prostate tumorigenesis. Thus, genomic rearrangements may arise from transcriptional or chromatin aberrancies and engage prostate tumorigenic mechanisms.

Membrane-associated guanylate kinase with an inverted arrangement of protein-protein interaction domains (MAGI)2 (also called synaptic scaffolding molecule (S-SCAM), atrophin-1-interacting protein 1, activin receptor-interacting protein 1) is a scaffold protein that binds a wide variety of receptors, cell adhesion molecules and signalling molecules. It also interacts with other scaffold proteins and adaptors, and forms a protein network that supports cell junctions. As it is highly expressed in brain, the study on its roles in synaptic organization initially preceded. However, mounting evidence indicates that MAGI2/S-SCAM functions as a tumour suppressor and plays essential roles to maintain the integrity of cell structures in non-neuronal tissues. We review the articles regarding to MAGI2/S-SCAM outside brain and discuss future perspectives for the research of MAGI family proteins.

Long non-coding RNAs (lncRNAs) are non-protein-coding transcripts shown to play important roles in tumourigenesis and tumour progression. Our study aimed to examine expression of the lncRNA MAGI2-AS3 in breast cancer and to explore its function in cancer cell growth. First, MAGI2-AS3 expression levels in clinical samples and cell lines were determined by quantitative reverse transcription-polymerase chain reaction (qRT-PCR). The functional significance of MAGI2-AS3 in cancer cell proliferation and apoptosis was then examined in vitro. Our results showed MAGI2-AS3 to be down-regulated in breast cancer tissues compared to normal adjacent tissues. Moreover, MAGI2-AS3 markedly inhibited breast cancer cell growth and increased expression of Fas and Fas ligand (FasL). In conclusion, our data suggest that MAGI2-AS3 expression is decreased in breast cancer and that MAGI2-AS3 plays an important role as a tumour suppressor by targeting Fas and FasL signalling. These results provide new insight into novel clinical treatments for breast cancer.
