1. New Synthetic Quinolines as Cathepsin K Inhibitors
Cathepsin K is a papain-like cysteine protease and is responsible for collagen degradation in bone tissue and thus represents an important target for the development of new therapies for treating diseases such as osteoporosis. Quinolines are an important class of heterocyclic molecular leads with a great pharmacological potential and represent a relevant sca

2. Genes de cisteíno proteases (Catepsina L-like) de Trypanosoma rangeli: polimorfismo, relações filogenéticas e alvos para diagnóstico e genotipagem. / Cathepsin L-like genes of Trypanosoma rangeli: phylogenetic analysis and polymorphic sequences as markers for lineage genotyping and diagnosis.
Nós isolamos e seqüenciamos genes que codificam Catepsina L-like em diversos isolados de T.rangeli de humano, mamíferos silvestres e Rhodnius spp., do centro e sul da América. Análises filogenéticas de seqüências que codificam a proteína madura de T. rangeli, outras espécies de Trypanosoma e Leishmania e duas espécies de bodonídeos, posicionaram

3. Intestinal molecular physiology of Dysdercus peruvianus (Hemiptera) / Fisiologia molecular intestinal de Dysdercus Peruvianus (Hemiptera)
After identification of cathepsins L in vitro assays and in zimograms we began to purify this enzyme in insect midgut. The region V2 was selected as a source of material for purifying a cysteine proteinase because it contains most of the activity of that proteinase. After several attempts to purify this proteinase, an effective process was developed that avo

4. Characterization of the cathepsin-like cysteine proteinases of Schistosoma mansoni.
Adult Schistosoma mansoni parasites synthesize and secrete both cathepsin L and cathepsin B cysteine proteinases. These cysteine proteinase activities, believed to be involved in hemoglobin digestion by adult schistosomes, were characterized by using specific fluorogenic peptide substrates and zymography. Both cathepsin L- and B-like activities with pH optim

5. Alterations in cysteine proteinase content of rat lung associated with development of Pneumocystis carinii infection.
The rate of hydrolysis of three cysteine-type proteinase substrates, N-benzyloxycarbonyl-Arg-Arg-4-methyl-7-coumarylamide (AMC) (cathepsin B), Arg-AMC (cathepsin H), and N-benzyloxycarbonyl-Phe-Arg-AMC (cathepsin L), were determined in rat lung throughout the time course of the induction of Pneumocystis carinii infection by immunosuppression. Cathepsin B-lik

6. Cysteine Proteases and Cell Differentiation: Excystment of the Ciliated Protist Sterkiella histriomuscorum
The process of excystment of Sterkiella histriomuscorum (Ciliophora, Oxytrichidae) leads in a few hours, through a massive influx of water and the resorption of the cyst wall, from an undifferentiated resting cyst to a highly differentiated and dividing vegetative cell. While studying the nature of the genes involved in this process, we isolated three differ

7. Characterization of the Entire Cystatin Gene Family in Barley and Their Target Cathepsin L-Like Cysteine-Proteases, Partners in the Hordein Mobilization during Seed Germination1[W]
Plant cystatins are inhibitors of cysteine-proteases of the papain C1A and legumain C13 families. Cystatin data from multiple plant species have suggested that these inhibitors act as defense proteins against pests and pathogens and as regulators of protein turnover. In this study, we characterize the entire cystatin gene family from barley (Hordeum vulgare)

8. Cloning and Expression of the Major Secreted Cathepsin B-Like Protein from Juvenile Fasciola hepatica and Analysis of Immunogenicity following Liver Fluke Infection
The functions of the cathepsin B-like proteases in liver flukes are unknown and analysis has been hindered by a lack of protein for study, since the protein is produced in small amounts by juvenile flukes. To circumvent this, we isolated and characterized a cDNA encoding the major secreted cathepsin B from Fasciola hepatica. The predicted preproprotein is 33

9. Recombinant Expression and Localization of Schistosoma mansoni Cathepsin L1 Support Its Role in the Degradation of Host Hemoglobin
Cysteine proteinases expressed by schistosomes appear to play key roles in the digestion of host hemoglobin, the principal source of amino acid nutrients utilized by these parasites. We have shown previously that the predominant cysteine proteinase activity in soluble extracts and excretory/secretory (ES) products of adults of Schistosoma mansoni and S. japo

10. Progesterone-regulated genes in the ovulation process: ADAMTS-1 and cathepsin L proteases
Ovulation is a precisely timed process by which a mature oocyte is released from an ovarian follicle. This process is initiated by the pituitary surge of luteinizing hormone (LH), is temporally associated with transcriptional regulation of numerous genes, and is presumed to involve the synthesis and/or activation of specific proteases that degrade the follic

11. Differential trafficking of live and dead Mycobacterium marinum organisms in macrophages.
We characterized the Mycobacterium marinum phagosome by using a variety of endocytic markers to follow the path of the bacteria through a mouse macrophage cell line. Using a laser confocal microscope, we found that the majority of viable M. marinum cells were in nonacidic vacuoles that did not colocalize with the vacuolar proton ATPase (V-ATPase), the calciu

12. Inducible targeting of IL-13 to the adult lung causes matrix metalloproteinase– and cathepsin-dependent emphysema
Cigarette smoke exposure is the major cause of chronic obstructive pulmonary disease (COPD). However, only a minority of smokers develop significant COPD, and patients with asthma or asthma-like airway hyperresponsiveness or eosinophilia experience accelerated loss of lung function after cigarette smoke exposure. Pulmonary inflammation is a characteristic fe
