Plakophilin3 (PKP3) loss results in increased transformation in multiple cell lines in vitro and increased tumor formation in vivo. A microarray analysis performed in the PKP3 knockdown clones, identified an inflammation associated gene signature in cell lines derived from stratified epithelia as opposed to cell lines derived from simple epithelia. However, in contrast to the inflammation assoc...

Mutations of genes in tumor cells of Triple Negative subset of Breast Cancer (TNBC) deregulate pathways of signal transduction. The loss of tumor suppressor gene PTEN is the most common first event associated with basal-like subtype (Martins, De, Almendro, Gonen, and Park, 2012). Here we report for the first time that the functional upregulation of secreted-MMP7, a transcriptional target of Wnt...

Previously, we showed that ACh-induced proliferation of human colon cancer cells is mediated by transactivation of epidermal growth factor (EGF) receptors (EGFRs). In the present study, we elucidate the molecular mechanism underlying this action. ACh-induced proliferation of H508 colon cancer cells, which express exclusively M3 muscarinic receptors (M3Rs), was attenuated by anti-EGFR ligand bin...

In rats, tolerance to MHC-incompatible renal allografts can be induced by the administration of anti-donor class II Abs on the day of transplantation. In this study we explored the mechanisms involved in the maintenance phase of this tolerance by analyzing intragraft gene expression profiles by microarray in long-term accepted kidneys. Comparison of the gene expression patterns of tolerated to ...

Non-steroidal anti-inflammatory drugs (NSAIDs) have shown potential as chemopreventive agents against cancer formation, especially colorectal cancers. However, the mechanisms by which these drugs act are not fully understood. In this study, Apc(Min/+) mice, a genetic model of human familial adenomatous polyposis, were treated with sulindac, and these mice demonstrated tumor reduction of >80%, c...

PURPOSE Several genes that are associated with protection from or susceptibility to trachomatous trichiasis (TT) have been identified through genetic association studies. Yet there have been few studies in which gene expression profiles were assessed in TT cases and disease-free controls. The purpose was to identify genes that are differentially expressed in the upper tarsal conjunctiva of subj...

Objectives: This study aimed to explore the effect of AXIN2 and MMP7 polymorphisms on non-small cell lung cancer (NSCLC) susceptibility; in addition, the interaction between gene polymorphisms and environment was also displayed. Methods: The genotyping was conducted by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in 102 patients with NSCLC and 120 healthy contro...

BACKGROUND Mutations in the transcription factor SOX18 are responsible for specific cardiovascular defects in humans and mice. In order to gain insight into the molecular basis of its action, we identified target genes of SOX18 and analyzed one, MMP7, in detail. METHODOLOGY/PRINCIPAL FINDINGS SOX18 was expressed in HUVEC using a recombinant adenoviral vector and the altered gene expression pr...

background and objective: mmp enzymes are a family of membrane proteins that are capable of digesting extracellular matrix compounds (ecm) and basement membrane. matrilysin enzyme is the smallest member of mmp family that is encoded by mmp-7 gene (matrilysin). according to the reports, g allele of -181 a/g single nucleotide polymorphism of mmp-7 gene causes an increase in the expression of this...
