The secreted semaphorin Sema3E controls cell migration and invasiveness in cancer cells. Sema3E-receptor, PlexinD1, is frequently upregulated in melanoma, breast, colon, ovarian and prostate cancers; however, the mechanisms underlying PlexinD1 upregulation and the downstream events elicited in tumor cells are still unclear. Here we show that the canonical RBPjk-dependent Notch signaling cascade controls PlexinD1 expression in primary endothelial and cancer cells. Transcriptional activation was studied by quantitative PCR and promoter activity reporter assays...

Uveal melanoma (UM) is the most commonly diagnosed primary intraocular tumor in adults. Familial UM (FUM), defined as two or more family members diagnosed with UM, is rare and estimated at less than 1% of all UM. Currently, BAP1 is the only gene known to contribute significant risk for UM. In this study we aimed to estimate the frequency of BAP1 mutation in FUM and to characterize the family and personal histories of other cancers in these families. We identified 32 families with FUM, including seven families previously reported by our group...

Positron emission tomography (PET) imaging has transformed diagnostic nuclear medicine and become an essential strategy in cancer management. With the expected growth of this molecular imaging modality, there is a recognized need for new PET probes to address the clinical challenges in the early diagnosis and staging of various types of cancers. In this endeavor, the prospect of using 64Cu in the form of simple Cu2+ ions as PET probe is not only a cost-effective proposition, but also seems poised to broaden the palette of molecular imaging probes in the foreseeable future...

: In patients with lung cancer (LC), malignant melanoma (MM), gastroenteropancreatic neuroendocrine tumours (GEP-NETs) and prostate cancer (PCA), N-staging is often performed by integrated (18)F-FDG-Positron Emission Tomography/Computed Tomography (PET/CT) (LC, MM), (68)Ga-DOTATOC-PET/CT (GEP-NET) and (68)Ga-PSMA-PET/CT (PCA): N-staging is not always accurate due to indeterminate PET-findings. To better evaluate malignant lymph node (LN) infiltration, additional surrogate parameters, especially in cases with indeterminate PET-findings, would be helpful...

Secreted frizzled related protein 3 (SFRP3) contains a cysteine-rich domain (CRD) that shares homology with Frizzled CRD and regulates WNT signaling. Independent studies showed epigenetic silencing of SFRP3 in melanoma and hepatocellular carcinoma. Moreover, a tumor suppressive function of SFRP3 was shown in androgen-independent prostate and gastric cancer cells. The current study is the first to investigate SFRP3 expression and its potential clinical impact on non-small cell lung carcinoma (NSCLC). WNT signaling components present on NSCLC subtypes were preliminary elucidated by expression data of The Cancer Genome Atlas (TCGA)...

Increased circulating alpha-1-antitrypsin (AAT) correlates with cancer stage/aggressiveness, but its role in cancer biology is unclear. We revealed antagonistic effect of AAT to cisplatin-induced cytotoxicity in prostate (PC3) and melanoma (A375) cancer cell lines. Moreover, AAT abrogated cytotoxicity of MEK inhibitor U0126 in PC3 cell line. Weaker antagonistic effect of AAT on cytotoxicity of PI3/Akt and NF-kB inhibitors was also observed. In addition, cisplatin increased AAT gene expression in transfected PC3 cells...

BACKGROUND: To examine the site-specific cancer mortality among deaths registered with Parkinson's disease (PD) and multiple sclerosis (MS). We focused on the patterns related to the most frequent cancers. METHODS: We analyzed Swiss mortality data over a 39-year period (1969-2007), using a statistical approach applicable to unique daabases, i.e. when no linkage with morbidity databases or disease registries is possible. It was based on a case-control design with bootstrapping to derive standardized mortality ratios (SMR)...

Metastasis is the major cause of cancer deaths and control of gene transcription has emerged as a critical contributing factor. RhoA- and RhoC-induced gene transcription via the actin-regulated transcriptional co-activator megakaryocytic leukemia (MKL) and serum response factor (SRF) drive metastasis in breast cancer and melanoma. We recently identified a compound, CCG-1423, which blocks Rho/MKL/SRF-mediated transcription and inhibits PC-3 prostate cancer cell invasion. Here, we undertook a genome-wide expression study in PC-3 cells to explore the mechanism and function of this compound...
