Transforming Growth Factor-Β (TGF-Β)–Inducible Gene TMEPAI Converts TGF-Β from a Tumor Suppressor to a Tumor Promoter in Breast Cancer
Published OnlineFirst July 7, 2010; DOI: 10.1158/0008-5472.CAN-10-1180 Published OnlineFirst on July 7, 2010 as 10.1158/0008-5472.CAN-10-1180 Priority Report Cancer Research Transforming Growth Factor-β (TGF-β)–Inducible Gene TMEPAI Converts TGF-β from a Tumor Suppressor to a Tumor Promoter in Breast Cancer Prajjal K. Singha, I-Tien Yeh, Manjeri A. Venkatachalam, and Pothana Saikumar Abstract TMEPAI is a transforming growth factor-β (TGF-β)–induced transmembrane protein that is overexpressed in several cancers. How TMEPAI expression relates to malignancy is unknown. Here, we report high expres- sion of TMEPAI in estrogen receptor/progesterone receptor–negative and human epidermal growth factor receptor-2–negative breast cancer cell lines and primary breast cancers that was further increased by TGF- β treatment. Basal and TGF-β–induced expression of TMEPAI were inhibited by the TGF-β receptor antag- onist SB431542 and overexpression of Smad7 or a dominant-negative mutant of Alk-5. TMEPAI knockdown attenuated TGF-β–induced growth and motility in breast cancer cells, suggesting a role for TMEPAI in growth promotion and invasiveness. Further, TMEPAI knockdown decreased breast tumor mass in a mouse xenograft model in a manner associated with increased expression of phosphatase and tensin homologue (PTEN) and diminished phosphorylation of Akt. Consistent with the effects through the phosphatidylinositol 3-kinase pathway, tumors with TMEPAI knockdown exhibited elevated levels of the cell cycle inhibitor p27kip1 and attenuated levels of DNA replication and expression of hypoxia-inducible fator 1α and vascular endothelial growth factor. Together, these results suggest that TMEPAI functions in breast cancer as a molecular switch that converts TGF-β from a tumor suppressor to a tumor promoter. -

It has been reported Wnt signaling that TMEPAI functions to suppress TGF-β and androgen signaling but here, we report a novel function of β-catenin TMEPAI in Wnt signaling suppression. First, we show that TMEPAI significantly inhibits TCF/LEF transcriptional activity stimulated by Wnt3A, LiCl, and β-catenin. Mechanistically, TMEPAI overexpression prevented β-catenin accumulation in the nucleus and TMEPAI knockout in triple negative breast cancer cell lines promoted β-catenin stability and nuclear accumulation together with increased mRNA levels of Wnt target genes AXIN2 and c-MYC. -

Expressed at high levels in prostate, kidney and ovary, PMEPA1 interacts with NEDD4 and may play a role in regulating AR (androgen receptor) levels, specifically in prostate cells. Down regulation of PMEPA1 is observed in prostate tumors, sµggesting that PMEPA1 may exhibit activity as a tumor suppressor. Overexpression of this protein may play a role in multiple types of cancer. Product Info Amount : 20 µg / 100 µg 200 µg/ml of Ab Purified from Bioreactor Concentrate by Protein A/G.

Characterization of a De Novo Ssmc 17 Detected in a Girl With
Stavber et al. Molecular Cytogenetics (2017) 10:10 DOI 10.1186/s13039-017-0312-x CASEREPORT Open Access Characterization of a de novo sSMC 17 detected in a girl with developmental delay and dysmorphic features Lana Stavber1, Sara Bertok2, Jernej Kovač1, Marija Volk3, Luca Lovrečić3, Tadej Battelino2,4 and Tinka Hovnik1* Abstract Background: The majority of small supernumerary marker chromosome cases arise de novo and their frequency in newborns is 0.04%. We report on a girl with developmental delay and dysmorphic features with a non-mosaic de novo sSMC that originated from the pericentric region of q arm in chromosome 17. Case presentation: The girl presented with developmental delay, speech delay, myopia, mild muscle hypotonia, hypoplasia of orbicular muscle, poor concentration, and hyperactivity. Main dysmorphic features included: round face, microstomia, small chin, down-slanting palpebral fissures and small lobules of both ears. At present, her developmental abilities are still delayed for her chronological age but she is making evident progress with speech. A postnatal array comparative genomic hybridization showed a 2.31 Mb genomic gain indicating microduplication derived from pericentric regions q11.1 and q11.2 of chromosome 17. Additional conventional cytogenetic analysis from peripheral blood characterized the karyotype as 47,XX,+mar in a non-mosaic form. The location of microduplication was confirmed with fluorescence in situ hybridization. Conclusion: The proband’s microduplication encompassed approximately 40 annotated genes, -
Investigating the Nedd4-Mediated
INVESTIGATING THE NEDD4-MEDIATED UBIQUITINATION OF PMEPA1, AND ITS POTENTIAL ROLE IN THE REGULATION OF THE ANDROGEN RECEPTOR AS PART OF THE STEROID RESPONSE PATHWAY IN PROSTATIC CANCER HELEN MARGARET MARKS School of Biological & Chemical Sciences, Queen Mary, University of London THESIS SUBMITTED TO THE UNIVERSITY OF LONDON FOR THE DEGREE OF DOCTOR OF PHILOSOPHY Page 1 of 229 Declaration DECLARATION BY CANDIDATE I declare that the work presented in this thesis is my own and that the thesis presented is the one upon which I expect to be examined. Any quotation or paraphrase from the published or unpublished work of another person has been duly acknowledged in the work which I present for examination. Signed (Candidate) .................................................. Date: .................. Page 2 of 229 Abstract ABSTRACT Ubiquitination is an extremely important post-translational modification, regulating a wide variety of cellular processes including proteasomal degradation, subcellular targeting, endocytosis and DNA repair. The HECT class of E3 ligases catalyse the final step of ubiquitin conjugation to the substrate; the Nedd4 family make up 9 members of this class in humans, and are implicated in pathologies ranging from congenital ion channel misregulation to cancer, via the TGF-ß signalling pathway. The Nedd4-like proteins contain WW substrate recognition domains, which recognise and bind proline–rich PY motifs. This work focuses on the interaction between Nedd4 and PMEPA1, a membrane protein showing altered expression in prostate cancer and a known Nedd4 substrate. PMEPA1 is recognised as important in several cancers, although its detailed function is not yet known; it is upregulated in prostate cancer and has been postulated to decrease cellular androgen receptor (AR) via a negative feedback loop involving Nedd4 in a ubiquitin-proteasome dependent process. -

However, determinants of resistance to oncolytic therapy are mostly unknown. We developed viral therapy-resistant cells and examined changes in gene-expression pattern compared with therapy-sensitive parental cells. Colon cancer cell line HT29 and hepatoma cell line PLC5 were exposed to increasing concentrations of virus G207. Therapy-resistant cells were isolated and grown in vitro. Tumorigenicity was confirmed by ability of cell lines to form tumors in mice. Human Genome U133A complementary DNA microarray chips were used to determine gene-expression patterns, which were analyzed in the context of molecular network interactions, pathways and gene ontology. In parental cell lines, 90–100% of cells were killed by day 7 at 1.0 multiplicity of infection. -
