Serpins, the largest family of endogenous protease inhibitors, target a wide variety of serine and cysteine proteases and play a role in a number of physiological and pathological states. The expression profiles of 20 serpins and 105 serine and cysteine proteases were determined across a panel of normal and diseased human tissues. In general, expression of serpins was highly restricted in both normal and diseased tissues, suggesting defined physiological roles for these protease inhibitors. A high correlation in expression for a particular serpin–protease pair in healthy tissues was often predictive of a biological interaction. The most striking finding was the dramatic change observed in the regulation of expression between proteases and their cognate inhibitors in diseased tissues. The loss of regulated serpin–protease matched expression may underlie the imbalanced protease activity observed in pathological states. © 2006 Elsevier Inc. All rights reserved.

    Biomarkers of Neonatal Skin Barrier Adaptation Reveal Substantial Differences Compared to Adult Skin

    www.nature.com/pr CLINICAL RESEARCH ARTICLE OPEN Biomarkers of neonatal skin barrier adaptation reveal substantial differences compared to adult skin Marty O. Visscher1,2, Andrew N. Carr3, Jason Winget3, Thomas Huggins3, Charles C. Bascom3, Robert Isfort3, Karen Lammers1 and Vivek Narendran1 BACKGROUND: The objective of this study was to measure skin characteristics in premature (PT), late preterm (LPT), and full-term (FT) neonates compared with adults at two times (T1, T2). METHODS: Skin samples of 61 neonates and 34 adults were analyzed for protein biomarkers, natural moisturizing factor (NMF), and biophysical parameters. Infant groups were: <34 weeks (PT), 34–<37 weeks (LPT), and ≥37 weeks (FT). RESULTS: Forty proteins were differentially expressed in FT infant skin, 38 in LPT infant skin, and 12 in PT infant skin compared with adult skin at T1. At T2, 40 proteins were differentially expressed in FT infants, 38 in LPT infants, and 54 in PT infants compared with adults. All proteins were increased at both times, except TMG3, S100A7, and PEBP1, and decreased in PTs at T1. The proteins are involved in filaggrin processing, protease inhibition/enzyme regulation, and antimicrobial function. Eight proteins were decreased in PT skin compared with FT skin at T1. LPT and FT proteins were generally comparable at both times. Total NMF was lower in infants than adults at T1, but higher in infants at T2. CONCLUSIONS: Neonates respond to the physiological transitions at birth by upregulating processes that drive the production of lower pH of the skin and water-binding NMF components, prevent protease activity leading to desquamation, and increase the 1234567890();,: barrier antimicrobial properties.

Biological function of mast cell chymase mMCP-4. In vitro and in vivo studies: a thorny pathway. Doctor's dissertation. ISSN 1401-6257, ISBN 91-576-6680-6 Mast cells (MCs) are key effector cells in various types of inflammatory conditions. The MC secretory granules contain inflammatory mediators such as histamine, heparin proteoglycan (PG), cytokines and various heparin-binding proteases, including tryptases, chymases and carboxypeptidase A. Previously, a mouse strain with a defect in its heparin biosynthesis was produced by targeting the gene for NDST-2 (N-deacetylase/N-sulfotransferase-2). These mice showed reduced levels of MC inflammatory mediators such as histamine and various heparin- binding proteases, including chymases, tryptases, and carboxypeptidase A. By using this mouse strain, we found that chymase in complex with heparin PG degraded fibronectin, suggesting a role for chymase in the regulation of connective tissue composition. Further, we found that chymase/heparin PG complexes degraded and thereby inactivated both thrombin and plasmin, suggesting an additional role for chymase in regulation of extravascular coagulation and fibrinolysis. However, although our findings implicated chymase in these processes, it was not possible to exclude the contribution to the observed activities by other MC components that are influenced by the knockout of NDST-2.

Frequently, PI is diagnosed as part of a larger clinical presentation in cystic fibrosis or Shwachman–Diamond syndrome. In this study, a mouse model for isolated exocrine PI was identified in a mouse line generated by a transgene insertion. The trait is inherited in an autosomal recessive pattern, and homozygous animals are growth retarded, have abnormal immunity, and have reduced life span. Mice with the disease locus, named pequen˜o (pq), exhibit progressive apoptosis of pancreatic acinar cells with severe exocrine acinar cell loss by 8 wk of age, while the islets and ductal tissue persist. The mutation in pq/pq mice results from a random transgene insertion. Molecular characterization of the transgene insertion site by fluorescent in situ hybridization and genomic deletion mapping identified an approximately 210-kb deletion on Chromosome 3, deleting two genes. One of these genes, Serpini2, encodes a protein that is a member of the serpin family of protease inhibitors. Reintroduction of only the Serpini2 gene by bacterial artificial chromosome transgenic complementation corrected the acinar cell defect as well as body weight and immune phenotypes, showing that deletion of Serpini2 causes the pequen˜o phenotype.

We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated.

  • Differential Gene Expression of Serine Protease Inhibitors in Bovine

    Differential Gene Expression of Serine Protease Inhibitors in Bovine

    Hayashi et al. Reproductive Biology and Endocrinology 2011, 9:72 http://www.rbej.com/content/9/1/72 RESEARCH Open Access Differential gene expression of serine protease inhibitors in bovine ovarian follicle: possible involvement in follicular growth and atresia Ken-Go Hayashi, Koichi Ushizawa, Misa Hosoe and Toru Takahashi* Abstract Background: SERPINs (serine protease inhibitors) regulate proteases involving fibrinolysis, coagulation, inflammation, cell mobility, cellular differentiation and apoptosis. This study aimed to investigate differentially expressed genes of members of the SERPIN superfamily between healthy and atretic follicles using a combination of microarray and quantitative real-time PCR (QPCR) analysis. In addition, we further determined mRNA and protein localization of identified SERPINs in estradiol (E2)-active and E2-inactive follicles by in situ hybridization and immunohistochemistry. Methods: We performed microarray analysis of healthy (10.7 +/- 0.7 mm) and atretic (7.8 +/- 0.2 mm) follicles using a custom-made bovine oligonucleotide microarray to screen differentially expressed genes encoding SERPIN superfamily members between groups. The expression profiles of six identified SERPIN genes were further confirmed by QPCR analysis. In addition, mRNA and protein localization of four SERPINs was investigated in E2- active and E2-inactive follicles using in situ hybridization and immunohistochemistry. Results: We have identified 11 SERPIN genes expressed in healthy and atretic follicles by microarray analysis. QPCR analysis confirmed that mRNA expression of four SERPINs (SERPINA5, SERPINB6, SERPINE2 and SERPINF2) was greater in healthy than in atretic follicles, while two SERPINs (SERPINE1 and SERPING1) had greater expression in atretic than in healthy follicles. In situ hybridization showed that SERPINA5, SERPINB6 and SERPINF2 mRNA were localized in GCs of E2-active follicles and weakly expressed in GCs of E2-inactive follicles.
