differential expressions of bmpr1α actn4α and fabp7 in hirschsprung disease
International Journal of Clinical and Experimental Pathology, 2014Co-Authors: Weilin Wang, Dong Chen, Hong GaoAbstract:Hirschsprung disease (HSCR) is characterized by the absence of intramural ganglion cells in the nerve plexuses of the distal gut. Recent studies have shown that the bone morphogenetic protein receptor-type IA (BMPR1α), Actinin-Alpha 4 (ACTN4α) and fatty acid binding protein 7 (FABP7) play important roles in the differentiation and development of neurons. The aganglionic (stenotic) and the ganglionic (normal) colon segment tissues of 60 HSCR patients were collected to investigate the expression pattern of BMPR1α, Actinin-4α and FABP7 using RT-PCR, quantitative real-time RT-PCR (qRT-PCR) and immunohistochemical staining. The mRNA and protein expressions of BMPR1α and ACTN4α were higher in the stenotic colon segment tissue than those in the normal colon segment tissue. However, the mRNA and protein expressions of FABP7 were lower in the stenotic colon segment tissue than those in the normal colon segment tissue. The study in HSCR patients, findings in mRNA and protein alterations to expecting provide more information to in order to find some clue for the pathomechanism of HSCR disease.

The effects of Lactobacillus plantarum on small intestinal barrier function and mucosal gene transcription; a randomized double-blind placebo controlled trial
2017Co-Authors: Mujagic Zlatan, Paul Vos, Boekschoten Mark, Govers Coen, Pieters, Harm J.h.m., Nicole Wit, Bron, Peter A., Masclee, Ad A.m., Troost, Freddy J.Abstract:The aim of this study was to investigate the effects of three Lactobacillus plantarum strains on in-vivo small intestinal barrier function and gene transcription in human subjects. The strains were selected for their differential effects on TLR signalling and tight junction protein rearrangement, which may lead to beneficial effects in a stressed human gut mucosa. Ten healthy volunteers participated in four different intervention periods: 7-day oral intake of either L. plantarum WCFS1, CIP48 (CIP104448), TIFN101 (CIP104450) or placebo, proceeded by a 4 weeks wash-out period. Lactulose-rhamnose ratio (an indicator of small intestinal permeability) increased after intake of indomethacin, which was given as an artificial stressor of the gut mucosal barrier (mean ratio 0.06±0.04 to 0.10±0.06, p=0.001), but was not significantly affected by the bacterial interventions. However, gene transcription pathway analysis in small intestinal biopsies, obtained by gastroduodenoscopy, demonstrated that particularly L. plantarum TIFN101 modulated cell-cell adhesion with high turnover of genes involved in tight- and adhesion junction protein synthesis and degradation (e.g. Actinin Alpha-4, metalloproteinase-2). These effects were less pronounced for L. plantarum WCFS1 and CIP104448. In conclusion, L. plantarum TIFN101 induced the most pronounced probiotic properties with specific effects on repair processes in the compromised intestine of healthy subjects

Motility-related Actinin Alpha-4 is associated with advanced and metastatic ovarian carcinoma
Laboratory Investigation, 2008Co-Authors: Maria V Barbolina, Brian P Adley, David L Kelly, Angela J Fought, Denise M Scholtens, Lonnie D Shea, M Sharon StackAbstract:Advanced and metastatic ovarian cancer is a leading cause of death from gynecologic malignancies. A more detailed understanding of the factors controlling invasion and metastasis may lead to novel anti-metastatic therapies. To model cellular interactions that occur during intraperitoneal metastasis, comparative cDNA microarray analysis and confirmatory real-time reverse transcription PCR (RT-PCR) were employed to uncover changes in gene expression that may occur in late stage ovarian cancer in response to microenvironmental cues, particularly native three-dimensional collagen I. Gene expression in human ovarian carcinoma tissues was evaluated on the RNA and protein level using real-time RT-PCR and immunohistochemistry. Cell invasion and migration were evaluated in a collagen invasion assay and a scratch wound assay. Three-dimensional collagen I culture led to differential expression of several genes. The role of Actinin Alpha-4 (ACTN4), a cytoskeleton-associated protein implicated in the regulation of cell motility, was examined in detail. ACTN4 RNA and protein expression were associated with advanced and metastatic human ovarian carcinoma. This report demonstrates that a cytoskeletal-associated protein ACTN4 is upregulated by three-dimensional collagen culture conditions, leading to increased invasion and motility of ovarian cancer cells. Expression of ACTN4 in human ovarian tumors was found to be associated with advanced-stage disease and peritoneal metastases.
