  • In a Three-Dimensional Reconstructed Human Epidermis Filaggrin-2 Is Essential for Proper Cornification

In a cohort of African-American children, a FLG2 nonsense mutation has been associated with the disease. In the epidermis of European patients, the expression of filaggrin-2, the filaggrin-related protein encoded by FLG2, is decreased. To describe the function of filaggrin-2 and evaluate the impact of its deficiency, its expression was downregulated using lentivirus-mediated shRNA interference in a three-dimensional reconstructed human epidermis (RHE) model. This resulted in parakeratosis and a compact stratum corneum, presence of abnormal vesicles inside the corneocytes, increased pH and reduced amounts of free amino acids at the RHE surface, leading to increased sensitivity to UVB radiations. The expression of differentiation markers was slightly modified. However, we observed reduced proteolytic processing of corneodesmosin, hornerin and filaggrin in parallel with reduced amounts of caspase-14 and bleomycin hydrolase. Our data demonstrated that filaggrin-2 is important for a proper cornification and a functional stratum corneum. Its downregulation in atopic patients may be involved in the disease-associated epidermis impairment.

  • Families and Clans of Cysteine Peptidases
    Families and clans of eysteine peptidases Alan J. Barrett* and Neil D. Rawlings Peptidase Laboratory. Department of Immunology, The Babraham Institute, Cambridge CB2 4AT,, UK. Summary The known cysteine peptidases have been classified into 35 sequence families. We argue that these have arisen from at least five separate evolutionary origins, each of which is represented by a set of one or more modern-day families, termed a clan. Clan CA is the largest, containing the papain family, C1, and others with the Cys/His catalytic dyad. Clan CB (His/Cys dyad) contains enzymes from RNA viruses that are distantly related to chymotrypsin. The peptidases of clan CC are also from RNA viruses, but have papain-like Cys/His catalytic sites. Clans CD and CE contain only one family each, those of interleukin-ll3-converting enz3wne and adenovirus L3 proteinase, respectively. A few families cannot yet be assigned to clans. In view of the number of separate origins of enzymes of this type, one should be cautious in generalising about the catalytic mechanisms and other properties of cysteine peptidases as a whole. In contrast, it may be safer to gener- alise for enzymes within a single family or clan. Introduction Peptidases in which the thiol group of a cysteine residue serves as the nucleophile in catalysis are defined as cysteine peptidases. In all the cysteine peptidases discovered so far, the activity depends upon a catalytic dyad, the second member of which is a histidine residue acting as a general base. The majority of cysteine peptidases are endopeptidases, but some act additionally or exclusively as exopeptidases.

  • A Genomic Analysis of Rat Proteases and Protease Inhibitors
    A genomic analysis of rat proteases and protease inhibitors Xose S. Puente and Carlos López-Otín Departamento de Bioquímica y Biología Molecular, Facultad de Medicina, Instituto Universitario de Oncología, Universidad de Oviedo, 33006-Oviedo, Spain Send correspondence to: Carlos López-Otín Departamento de Bioquímica y Biología Molecular Facultad de Medicina, Universidad de Oviedo 33006 Oviedo-SPAIN Tel. 34-985-104201; Fax: 34-985-103564 E-mail: [email protected] Proteases perform fundamental roles in multiple biological processes and are associated with a growing number of pathological conditions that involve abnormal or deficient functions of these enzymes. The availability of the rat genome sequence has opened the possibility to perform a global analysis of the complete protease repertoire or degradome of this model organism. The rat degradome consists of at least 626 proteases and homologs, which are distributed into five catalytic classes: 24 aspartic, 160 cysteine, 192 metallo, 221 serine, and 29 threonine proteases. Overall, this distribution is similar to that of the mouse degradome, but significatively more complex than that corresponding to the human degradome composed of 561 proteases and homologs. This increased complexity of the rat protease complement mainly derives from the expansion of several gene families including placental cathepsins, testases, kallikreins and hematopoietic serine proteases, involved in reproductive or immunological functions. These protease families have also evolved differently in the rat and mouse genomes and may contribute to explain some functional differences between these two closely related species. Likewise, genomic analysis of rat protease inhibitors has shown some differences with the mouse protease inhibitor complement and the marked expansion of families of cysteine and serine protease inhibitors in rat and mouse with respect to human.

  • Knockdown of Filaggrin in a Three-Dimensional Reconstructed
    ORIGINAL ARTICLE Knockdown of Filaggrin in a Three-Dimensional Reconstructed Human Epidermis Impairs Keratinocyte Differentiation Vale´rie Pendaries1,2,3, Jeremy Malaisse4, Laurence Pellerin1,2,3, Marina Le Lamer1,2,3, Rachida Nachat1,2,3,8, Sanja Kezic5, Anne-Marie Schmitt6,CarlePaul1,2,3,7, Yves Poumay4, Guy Serre1,2,3 and Michel Simon1,2,3 Atopic dermatitis is a chronic inflammatory skin disorder characterized by defects in the epidermal barrier and keratinocyte differentiation. The expression of filaggrin, a protein thought to have a major role in the function of the epidermis, is downregulated. However, the impact of this deficiency on keratinocytes is not really known. This was investigated using lentivirus-mediated small-hairpin RNA interference in a three-dimensional recon- structed human epidermis (RHE) model, in the absence of other cell types than keratinocytes. Similar to what is known for atopic skin, the experimental filaggrin downregulation resulted in hypogranulosis, a disturbed corneocyte intracellular matrix, reduced amounts of natural moisturizing factor components, increased permeability and UV-B sensitivity of the RHE, and impaired keratinocyte differentiation at the messenger RNA and protein levels. In particular, the amounts of two filaggrin-related proteins and one protease involved in the degradation of filaggrin, bleomycin hydrolase, were lower. In addition, caspase-14 activation was reduced. These results demonstrate the importance of filaggrin for the stratum corneum properties/functions. They indicate that filaggrin downregulation in the epidermis of atopic patients, either acquired or innate, may be directly responsible for some of the disease-related alterations in the epidermal differentiation program and epidermal barrier function.

Presland7,8, Hidenari Takahara9, Gerwin Puppels3,10, Peter Caspers3,10, Peter Vandenabeele1,2 and Wim Declercq1,2 Caspase-14 is a protease that is mainly expressed in suprabasal epidermal layers and activated during keratinocyte cornification. Caspase-14-deficient mice display reduced epidermal barrier function and increased sensitivity to UVB radiation. In these mice, profilaggrin, a protein with a pivotal role in skin barrier function, is processed correctly to its functional filaggrin (FLG) repeat unit, but proteolytic FLG fragments accumulate in the epidermis. In wild-type stratum corneum, FLG is degraded into free amino acids, some of which contribute to generation of the natural moisturizing factors (NMFs) that maintain epidermal hydration. We found that caspase-14 cleaves the FLG repeat unit and identified two caspase-14 cleavage sites. These results indicate that accumulation of FLG fragments in caspase-14À/À mice is due to a defect in the terminal FLG degradation pathway. Consequently, we show that the defective FLG degradation in caspase-14-deficient skin results in substantial reduction in the amount of NMFs, such as urocanic acid and pyrrolidone carboxylic acid.

  • Purification and Characterization of Bleomycin Hydrolase, Which Represents a New Family of Cysteine Proteases, from Rat Skin
    J. Biochem. 119, 29-36 (1996) Purification and Characterization of Bleomycin Hydrolase, Which Represents a New Family of Cysteine Proteases, from Rat Skin Atsushi Takeda,*,' Dousei Higuchi,t Takako Yamamoto ,* Yoshiko Nakamura,* Y utaka Masuda,t Takahiro Hirabayashi,t and Kazuyasu Nakaya•ö Departments of *Clinical Pathology and tDermatology , Showa University Fujigaoka Hospital, 1-30 Fujigaoka, A oba-ku, Yokohama 227; and•öDepartment of Biochemistry, School of Pharmaceutical Sciences, Showa University, 1-5-8 Hatanodai, Shinagawa-ku, Tokyo 142 Received for publication, June 12 , 1995 Bleomycin (BLM) hydrolase, which hydrolyzes the carboxyamide bond in the ,ƒÀ-amino alanine moiety, was purified from newborn rat skin. The enzyme was purified 2,500-fold over the crude extract to apparent homogeneity in five steps in the presence of 2-mercap toethanol: 45-55% ammonium sulfate fractionation, followed by chromatographies on Sephacryl S-200, DEAE-cellulofine, Phe-Superose, and Mono Q ion-exchange. The native enzyme had a molecular mass of 280kDa according to gel filtration. The subunit molecular mass was estimated as 48kDa by SDS-PAGE, indicating that the enzyme was comprised of six identical subunits. The amino acid sequence of its NH,-terminus was determined to be acetyl-Met-Asn-Asn-Ala-Gly-Leu-Asn-Ser-Glu-Lys-, which was not found in the amino acid sequence database. The optimum pH of the enzyme was 7.5 with pepleomycin (PLM). The Km and Vmax values were 2.1mM and 6.8ƒÊmol•Emg-1•Eh-1 for PLM, and 1.8mM and 7.2 ƒÊ mol•Emg-1•Eh-1 for BLM-A2, respectively.
