  1. β-Adrenergic agonists differentially regulate highly selective and nonselective epithelial sodium channels to promote alveolar fluid clearan...
    Charles A CA Downs, Lisa H LH Kriener, ... My N MN Helms

    Am J Physiol Lung Cell Mol Physiol 302(11):L1167-78 (2012) PMID 22505670

    We hypothesized that stimulation with β(1)-AR agonist (denopamine) or β(2)-AR agonist (terbutaline) would increase HSC and/or NSC channel activity in alveolar epithelial cells. We performed single-channel measurements from T1 and T2 cells accessed from rat lung slices. Terbutaline (20 μM) increas...
  2. Transglutaminase 2 expression is enhanced synergistically by interferon-γ and tumour necrosis factor-α in human small intestine.
    M M Bayardo, F F Punzi, ... F F Chirdo

    Clin Exp Immunol 168(1):95-104 (2012) PMID 22385244

    We report that IFN-γ was the most potent inducer of TG2 expression in the small intestinal mucosa and in four [Caco-2, HT-29, Calu-6 and human acute monocytic leukaemia cell line (THP-1)] of five cell lines tested. The combination of TNF-α and IFN-γ produced a strong synergistic effect. The use o...
  3. Corticosteroid-induced gene expression in allergen-challenged asthmatic subjects taking inhaled budesonide.
    M M MM Kelly, E M EM King, ... R R Newton

    Br J Pharmacol 165(6):1737-47 (2012) PMID 21827450 PMCID PMC3372826

    We have assessed whether ICS induce anti-inflammatory gene expression in subjects with atopic asthma. Bronchial biopsies from allergen-challenged atopic asthmatic subjects taking inhaled budesonide or placebo were subjected to gene expression analysis using real-time reverse transcri...

  4. BRCA1 haploinsufficiency: consequences for breast cancer.
    Salmena L and Narod S

    pubmed 8(2):127-9 1 Mar 2012 PMID 22375716

    In their study, Konishi et al. generate and study cell lines that carry one mutant and one normal copy of BRCA1. These heterozygous (noncancerous) cells are noteworthy in that they carry an increased number of copy number alterations and have diminished DNA repair capacity. These observations go beyo...
  5. The role of SPINK5 in asthma related physiological events in the airway epithelium.
    Esra E Birben, Cansin C Sackesen, ... Omer O Kalayci

    Respir Med 106(3):349-55 (2012) PMID 22133475

    We have not observed any clear effect of SPINK5 on apoptosis. PAS staining showed that SPINK5 slightly decreased the mucin production induced by neutrophil elastase in A549 cells. However, SPINK5 had no effect on MUC5AC transcription. SPINK5 is an important molecule in asthma. Its ro...
  6. Human amniotic epithelial cell feeder layers maintain human iPS cell pluripotency via inhibited endogenous microRNA-145 and increased Sox2 e...
    Te T Liu, Weiwei W Cheng, ... Lihe L Guo

    Exp Cell Res 318(4):424-34 (2012) PMID 22200372

    We examined the effect of endogenous microRNA-145 regulation on Sox2 expression in human iPS cells by HuAECs feeder cells regulation, and in turn on human iPS cells pluripotency. We found that human IPS cells transfected with a microRNA-145 mutant expressed Sox2 at high levels, allowing iPS to maint...
  7. Ecotopic viral integration site 1 (EVI1) regulates multiple cellular processes important for cancer and is a synergistic partner for FOS pro...
    Emilie A EA Bard-Chapeau, Justin J Jeyakani, ... Neal G NG Copeland

    Proc Natl Acad Sci U S A 109(6):2168-73 (2012) PMID 22308434 PMCID PMC3277513

    We show that the two zinc finger domains of EVI1 bind to DNA independently and regulate different sets of target genes. Strikingly, an enriched fraction of EVI1 target genes are cancer genes or genes associated with cancer. We also show that more than 25% of EVI1-occupied genes contain linked EVI1 a...

  8. Gene expression networks in COPD: microRNA and mRNA regulation.
    Michael E ME Ezzie, Melissa M Crawford, ... S Patrick SP Nana-Sinkam

    Thorax 67(2):122-31 (2012) PMID 21940491

    We then examined both miRNA and mRNA expression to enrich for relevant biological pathways. 70 miRNAs and 2667 mRNAs were differentially expressed between lung tissue from subjects with COPD and smokers without COPD. miRNA and mRNA expression profiles enriched for biological pathways...
  9. Physiological and pathological role of local and immigrating colonic stem cells.
    Ferenc F Sipos, Gábor G Valcz, and Béla B Molnár

    World J Gastroenterol 18(4):295-301 (2012) PMID 22294835

    The latest avenue of research is revealing the existence of and role for the colonic stem cells in the physiological renewal of the mucosa and in pathological circumstances where they have both positive and negative effects. In the case of human colon, different levels of stem cell c...

  10. Virulence factors involved in the pathogenesis of the infection caused by the swine pathogen and zoonotic agent Streptococcus suis.
    Nahuel N Fittipaldi, Mariela M Segura, ... Marcelo M Gottschalk

    Future Microbiol 7(2):259-79 (2012) PMID 22324994

    We discuss the potential contribution of different described S. suis virulence factors at each step of the pathogenesis of the infection. Finally, we briefly discuss other described virulence factors, virulence factor candidates and virulence markers for which a precise role at specific steps of the...
