Activation of Xenopus eggs by proteases: possible involvement of a sperm protease in fertilization. (1/980)

Egg activation in cross-fertilization between Xenopus eggs and Cynops sperm may be caused by a protease activity against Boc-Gly-Arg-Arg-MCA in the sperm acrosome. To determine the role of the sperm protease in fertilization, the protease was purified from Cynops sperm using several chromatographic techniques. We found that purified sperm protease readily hydrolyzes Boc-Gly-Arg-Arg-MCA and Z-Arg-Arg-MCA, that protease activity was inhibited by the trypsin inhibitors aprotinin and leupeptin, and that not only the purified protease, but also cathepsin B, induces activation in Xenopus eggs. We inseminated unfertilized Xenopus eggs with homologous sperm in the presence of various peptidyl MCA substrates or protease inhibitors and demonstrated that trypsin inhibitors or MCA substrates containing Arg-Arg-MCA reversibly inhibited fertilization of both fully jellied and denuded eggs. Sperm motility was not affected by the reagents. An extract obtained from Xenopus sperm showed hydrolytic activity against Boc-Gly-Arg-Arg-MCA, Z-Arg-Arg-MCA, and Arg-MCA. These results suggest that the tryptic protease in Xenopus sperm is involved in fertilization, most likely by participating in egg activation.  (+info)

Cathepsin B immunohistochemical staining in tumor and endothelial cells is a new prognostic factor for survival in patients with brain tumors. (2/980)

The cysteine endopeptidase, cathepsin (Cat) B, and its endogenous inhibitor, stefin A, were found relevant for cancer progression of many neoplasms, including human brain tumors. Histological sections of 100 primary brain tumors, 27 benign and 73 malignant, were stained immunohistochemically for Cat B and stefin A. The immunohistochemical staining of Cat B in tumor cells, endothelial cells, and macrophages was scored separately from 0-12. The score in tumor and endothelial cells was significantly higher in malignant tumors compared with benign tumors (P<0.000). A significant correlation between immunostaining of Cat B (scored together for tumor and endothelial cells) and clinical parameters, such as duration of symptoms, Karnofsky score, psycho-organic symptoms, and histological score was demonstrated. Univariate survival analysis indicated that total Cat B score above 8 was a significant predictor for shorter overall survival (P = 0.003). In glioblastoma multiforme, intense Cat B staining of endothelial cells was a significant predictor for shorter survival (P = 0.003). Stefin A immunostaining was weak and detected only in a few benign and some malignant tumors, suggesting that this inhibitor alone is not sufficient in balancing proteolytic activity of Cat B. We conclude that specific immunostaining of Cat B in tumor and endothelial cells can be used to predict the risk of death in patients with primary tumors of the central nervous system.  (+info)

Expression and alteration of the S2 subsite of the Leishmania major cathepsin B-like cysteine protease. (3/980)

The mature form of the cathepsin B-like protease of Leishmania major (LmajcatB) is a 243 amino acid protein belonging to the papain family of cysteine proteases and is 54% identical to human-liver cathepsin B. Despite the high identity and structural similarity with cathepsin B, LmajcatB does not readily hydrolyse benzyloxycarbonyl-Arg-Arg-7-amino-4-methyl coumarin (Z-Arg-Arg-AMC), which is cleaved by cathepsin B enzymes. It does, however, hydrolyse Z-Phe-Arg-AMC, a substrate typically cleaved by cathepsin L and B enzymes. Based upon computer generated protein models of LmajcatB and mammalian cathepsin B, it was predicted that this variation in substrate specificity was attributed to Gly234 at the S2 subsite of LmajcatB, which forms a larger, more hydrophobic pocket compared with mammalian cathepsin B. To test this hypothesis, recombinant LmajcatB was expressed in the Pichia pastoris yeast expression system. The quality of the recombinant enzyme was confirmed by kinetic characterization, N-terminal sequencing, and Western blot analysis. Alteration of Gly234 to Glu, which is found at the corresponding site in mammalian cathepsin B, increased recombinant LmajcatB (rLmajcatB) activity toward Z-Arg-Arg-AMC 8-fold over the wild-type recombinant enzyme (kcat/Km=3740+/-413 M-1.s-1 versus 472+/-72.4 M-1.s-1). The results of inhibition assays of rLmajcatB with an inhibitor of cathepsin L enzymes, K11002 (morpholine urea-Phe-homoPhe-vinylsulphonylphenyl, kinact/Ki=208200+/-36000 M-1. s-1), and a cathepsin B specific inhibitor, CA074 [N-(L-3-trans-propylcarbamoyloxirane-2-carbonyl)-l-isoleucyl-l- prolin e, kinact/Ki=199200+/-32900 M-1.s-1], support the findings that this protozoan protease has the P2 specificity of cathepsin L-like enzymes while retaining structural homology to mammalian cathepsin B.  (+info)

Kappa light chain-associated Fanconi's syndrome: molecular analysis of monoclonal immunoglobulin light chains from patients with and without intracellular crystals. (4/980)

Plasma cell dyscrasias may be responsible for Fanconi's syndrome, due to the toxicity of a free monoclonal kappa light chain toward kidney proximal tubules. Eight cases of Fanconi's syndrome were analyzed. We compared the structures of VkappaI variability subgroup V domains from five cases of Fanconi's syndrome and one myeloma without renal involvement. Among Fanconi cases, four putative structures were obtained after molecular modeling by homology, and the other had previously been refined by X-ray crystallography. The complete sequences of one VkappaI, one VkappaIII and N-terminal sequences of two VkappaI light chains, from patients with different forms of Fanconi's syndrome, were compared with four previously studied sequences. All three kappa chains responsible for a 'classical' form with intralysosomal crystals and a low mass myeloma, were encoded by the LCO2/O12 germline gene and had an unusual non-polar residue exposed to the solvent in the CDR-L1 loop. Of both VkappaI light chains from patients with Fanconi's syndrome without intracellular crystals, one derived from LCO2/O12 and the other from LCO8/O18 gene. Another feature that could be related to non-crystallization was the absence of accessible side chains in the CDR-L3 loop which is known to be implicated in dimer formation.  (+info)

Collagenase, cathepsin B and cathepsin L gene expression in the synovial membrane of patients with early inflammatory arthritis. (5/980)

OBJECTIVE: To examine the expression of the matrix metalloproteinase, MMP-1, and the cysteine proteases, cathepsin B (CB) and cathepsin L (CL), in the synovial membrane (SM) of patients with early inflammatory arthritis. METHODS: Samples of SM were obtained by blind needle biopsy or needle arthroscopy from inflamed knees of 28 patients with early inflammatory arthritis (mean disease duration 10.2 months, range 2 weeks-18 months). Sixteen patients had rheumatoid arthritis (RA), nine psoriatic arthritis and there was one each with ankylosing spondylitis, gout and an undifferentiated arthritis. Comparison was made with tissue from two patients with established erosive RA and three normal synovial tissue samples. In situ hybridization was performed using digoxigenin-labelled RNA probes. RESULTS: MMP-1, CB and CL were expressed in all patients with early arthritis and in established erosive RA, whereas normal synovium showed only scanty expression. The three proteases were prominent in perivascular infiltrates and endothelial cells of early arthritis tissue. MMP-1 was observed primarily in the lining layer, but was also evident in the sublining area. CB and CL were expressed to a lesser extent in the lining layer, and were present mainly in the subintima. The three proteases were not found in lymphoid aggregrates. No differences were observed between the disease categories. CONCLUSIONS: The detection of MMP-1, CB and CL in the synovium shortly after symptom onset implies that the potential for joint destruction exists at a very early stage in the disease. In addition, the perivascular and endothelial cell expression suggests a role for these proteases in mononuclear cell influx to the inflamed synovium and in angiogenesis.  (+info)

Antigen secreted from noncytosolic Listeria monocytogenes is processed by the classical MHC class I processing pathway. (6/980)

Intracellular bacteria can reside in a vacuolar compartment, or they can escape the vacuole and become free living in the cytoplasm. The presentation of Ag by class I MHC molecules has been defined primarily for Ag present in the cytoplasm. It was therefore thought that Ags from bacteria that remain in a vacuole would not be presented by MHC class I molecules. Although some studies have provided data to support this idea, it is not necessarily true for all intracellular bacteria. For example, we have previously demonstrated that an epitope from the p60 protein secreted by LLO- Listeria monocytogenes, which does not reside in the cytoplasm, can be presented by MHC class I molecules to a T cell clone specific for the epitope, p60217-225. We have further examined the route by which Ag secreted by LLO- L. monocytogenes is presented by MHC class I molecules. Using pharmacological inhibitors, we demonstrate that MHC class I presentation of the p60 epitope derived from by LLO- L. monocytogenes requires phagolysosome fusion and processing by the proteasome. Lysosomal cathepsins, however, are not required for processing of the p60 epitope. Similarly, processing of the AttM epitope, secreted by LLO- L. monocytogenes and presented by H2-M3, also requires phagolysosome fusion and cleavage by the proteasome. Thus, p60 and AttM secreted by LLO- L. monocytogenes are processed via the classical class I pathway for presentation by MHC class I molecules.  (+info)

The affinity and kinetics of inhibition of cysteine proteinases by intact recombinant bovine cystatin C. (7/980)

Recent studies have shown that the bovine cysteine proteinase inhibitor, cystatin C, is synthesized as a preprotein containing a 118-residue mature protein. However, the forms of the inhibitor isolated previously from bovine tissues had shorter N-terminal regions than expected from these results, and also lower affinity for proteinases than human cystatin C. In this work, we report the properties of recombinant, full-length bovine cystatin C having a complete N-terminal region. The general characteristics of this form of the inhibitor, as reflected by the isoelectric point, the far-ultraviolet circular dichroism spectrum, the thermal stability and the changes of tryptophan fluorescence on interaction with papain, resembled those of human cystatin C. The affinity and kinetics of inhibition of papain and cathepsins B, H and L by the bovine inhibitor were also comparable with those of the human inhibitor, although certain differences were apparent. Notably, the affinity of bovine cystatin C for cathepsin H was somewhat weaker than that of human cystatin C, and bovine cystatin C bound to cathepsin L with about a four-fold higher association rate constant than the human inhibitor. This rate constant is comparable with the highest values reported previously for cystatin-cysteine proteinase reactions. The full-length, recombinant bovine cystatin C bound appreciably more tightly to proteinases than the shorter form characterized previously. Digestion of the recombinant inhibitor with neutrophil elastase resulted in forms with truncated N-terminal regions and appreciably decreased affinity for papain, consistent with the forms of bovine cystatin C isolated previously having arisen by proteolytic cleavage of a mature, full-length inhibitor.  (+info)

Accumulation of sialic acid in endocytic compartments interferes with the formation of mature lysosomes. Impaired proteolytic processing of cathepsin B in fibroblasts of patients with lysosomal sialic acid storage disease. (8/980)

The impact of an altered endocytic environment on the biogenesis of lysosomes was studied in fibroblasts of patients suffering from sialic acid storage disease (SASD). This inherited disorder is characterized by the accumulation of acidic monosaccharides in lysosomal compartments and a concomitant decrease of their buoyant density. We demonstrate that C-terminal trimming of the lysosomal cysteine proteinase cathepsin B is inhibited in SASD fibroblasts. This late event in the biosynthesis of cathepsin B normally takes place in mature lysosomes, suggesting an impaired biogenesis of these organelles in SASD cells. When normal fibroblasts are loaded with sucrose, which inhibits transport from late endosomes to lysosomes, C-terminal cathepsin B processing is prevented to the same extent. Further characterization of the terminal endocytic compartments of SASD cells revealed properties usually associated with late endosomes/prelysosomes. In addition to a decreased buoyant density, SASD "lysosomes" show a reduced acidification capacity and appear smaller than their normal counterparts. We conclude that the accumulation of small non-diffusible compounds within endocytic compartments interferes with the formation of mature lysosomes and that the acidic environment of the latter organelles is a prerequisite for C-terminal processing of lysosomal hydrolases.  (+info)

Inflammatory breast cancer (IBC) is an aggressive, metastatic and highly angiogenic form of locally advanced breast cancer with a relatively poor three-year survival rate. Breast cancer invasion has been linked to proteolytic activity at the tumor cell surface. Here we explored a role for active cathepsin B on the cell surface in the invasiveness of IBC. We examined expression of the cysteine protease cathepsin B and the serine protease urokinase plasminogen activator (uPA), its receptor uPAR and caveolin-1 in two IBC cell lines: SUM149 and SUM190. We utilized a live cell proteolysis assay to localize in real time the degradation of type IV collagen by IBC cells. IBC patient biopsies were examined for expression of cathepsin B and caveolin-1. Both cell lines expressed comparable levels of cathepsin B and uPA. In contrast, levels of caveolin-1 and uPAR were greater in SUM149 cells. We observed that uPA, uPAR and enzymatically active cathepsin B were colocalized in caveolae fractions isolated from SUM149
Electrospray mass spectrometric techniques were used to demonstrate that mature (single-chain) recombinant rat cathepsin B is capable of sequentially removing the three dipeptides which comprise the C-terminal extension of the proenzyme. A pepsin-cleaved form of a non-active mutant recombinant rat procathepsin B (Cys-29-Ser) was used as a substrate to study C-terminal processing by mature cathepsin B. The results indicate that the first two residues (Arg-Phe) are removed efficiently, while the remaining four (Gln-Tyr-Trp-Gly), particularly the final two, are much more resistant to proteolysis. These cleavages were pronounced at pH 5.0 compared with pH 6.0, in agreement with the lower pH optimum for cathepsin B exopeptidase activity reported previously. From this example of the peptidyldipeptidase activity of cathepsin B we conclude that removal of the C-terminal extension may occur in any intracellular compartment where active cathepsin B is found. ...

Mechanical stress plays a key role in the pathogenesis of cartilage destruction seen in osteoarthritis (OA). We investigated the effect of cyclic tensile stress (CTS) on the anabolic and catabolic gene expression of rat cultured normal chondrocytes using the Flexercell strain unit. The effects of interleukin (IL)-4, a chondroprotective cytokine, on the changes in gene expression induced by CTS were also investigated. CTS (7% elongation at 0.5 Hz) for 24 h did not affect the expression of aggrecan and type II collagen, whereas CTS significantly upregulated matrix metalloproteinase (MMP)-13 and cathepsin B mRNA expression by chondrocytes. IL-1beta expression was also signifi cantly upregulated by CTS up to 12 h. The upregulation of MMP-13 was observed at 3 h, which was earlier than that of IL-1beta. Furthermore, pre-treatment with IL-4 (10 ng/ml) suppressed both MMP-13 and cathepsin B induction by mechanical stress, as well as CTS-induced IL-1beta expression. Our results suggest that IL-4 might ...

Vectors based on different serotypes of adeno-associated virus hold great promise for human gene therapy, based on their unique tissue tropisms and distinct immunological profiles. A particularly interesting candidate is AAV8, which can efficiently and rapidly transduce a wide range of tissues in vivo. To further unravel the mechanisms behind AAV8 transduction, we used yeast two-hybrid analyses to screen a mouse liver complementary DNA library for cellular proteins capable of interacting with the viral capsid proteins. In total, we recovered approximately 700 clones, comprising over 300 independent genes. Sequence analyses revealed multiple hits for over 100 genes, including two encoding the endosomal cysteine proteases cathepsins B and L. Notably, these two proteases also physically interacted with the corresponding portion of the AAV2 capsid in yeast, but not with AAV5. We demonstrate that cathepsins B and L are essential for efficient AAV2- and AAV8-mediated transduction of mammalian cells, and
Podosomes mediate cell migration and invasion by coordinating the reorganization of actin cytoskeleton and focal matrix degradation. MMP and serine proteases have been found to function at podosomes. The lysosomal cysteine cathepsins, a third major class of matrix-degrading enzymes involved in tumor invasion and tissue remodeling, have yet to be linked to podosomes with the exception of cathepsin K in osteoclasts. Using inhibitors and shRNA-mediated depletion, we show that cathepsin B participates in podosomes-mediated focal matrix degradation and invasion in v-Src-transformed fibroblasts. We observed that lysosomal marker LAMP-1 localized at the center of podosome rosettes protruding into extracellular matrix using confocal microscopy. Time-lapse live-cell imaging revealed that lysosomal vesicles moved to and fused with podosomes. Disruption of lysosomal pH gradient with Bafilomycin A1, chloroquine, or ammonium chloride greatly enhanced the formation of podosomes and increased the matrix degradation.
Cathepsin B (CtsB) is a lysosomal cysteine proteinase that is specifically translocated to the extracellular milieu during cancer progression.

Ex vivo and in vivo studies confirmed selective targeting and internalization of LNC-NS-629 by tumor and stromal cells, thus validating CtsB targeting as a highly promising approach to cancer diagnosis and treatment ...

In mice with aggressive behavior, protease activity in the studied brain structures was not changed. In ...
There is considerable interest in investigating conserved roles for protease in the Hypersensitive Response (HR), a plant defence response which shares some morphological characteristics with apoptosis. a cysteine protease, with homology to mammalian Cathepsin B proteases, was isolated in a screen for genes up-regulated in the HR. The focus of this current research is to examine the roles of Cathepsin B genes in the model plant Arabidopsis. There are three Cathepsin B homologues in Arabidopsis for which knock-out lines were isolated and genetically crossed using a combination of T-DNA insert lines and RNAi to generate double and triple mutants. These genes were found to act redundantly with triple mutants showing increased susceptibility to both virulent and avirulent strains of Pseudomonas syringae DC3000. Moreover, these genes are also involved in non-host resistance to fungal pathogen Blumeria graminis f.sp. tritici, where they positively regulate the HR but negatively regulate ...

When hypertonicity is imposed with sufficient intensity and acuteness, cells die. Here we investigated the cellular pathways involved in death using a cell line derived from renal epithelium. We found that hypertonicity rapidly induced activation of an intrinsic cell death pathway- release of cytochrome c and activation of caspase-3 and caspase-9-and an extrinsic pathway-activation of caspase-8. Likewise, a lysosomal pathway of cell death characterized by partial lysosomal rupture and release of cathepsin B from lysosomes to the cytosol was also activated. Relationships among the pathways were examined using specific inhibitors. Caspase inhibitors did not affect cathepsin B release into the cytosol by hypertonicity. In addition, cathepsin B inhibitors and caspase inhibitors did not affect hyper-tonicity-induced cytochrome c release, suggesting that the three pathways were independently activated. Combined inhibition of caspases and cathepsin B conferred significantly more protection from ...
We synthesized one series of fluorogenic substrates for cathepsin B derived from the peptide Bz-F-R-MCA (Bz = benzoyl, MCA = 7-methyl-coumarin amide) substituting Phe at the P(2) position by non-natural basic amino acids that combine a positively charged group with aromatic or aliphatic radicals at the same side chain, namely, 4-aminomethyl-phenylalanine, 4-guanidine-phenylalanine. 4-aminomethyl-N-isopropyl-phenylalanine. 3-pyridyl-alanine, 4-piperidinyl-alanine, 4-amino-methyl-cyclohexyl-alanine. 4-aminocyclohexyl-alanine, and N(im)-dimethyl-histidine. Bz-F-R-MCA was the best substrate for cathepsin B but also hydrolyzed Bz-R-R-MCA with lower efficiency, since the protease accepts Arg at St due to the presence of Glu(245) at the bottom of this subsite. the presence of the basic non-natural amino acids at the Pt position of the substrate partially restored the catalytic efficiency of cathepsin B. All the kinetic parameters for hydrolysis of the peptides described in this paper are in accordance ...

3d0g), namely at residues 31, 35, 38, & 353 in ACE2 or residues 479 and 487 in the SARS-CoV RBD, are what allowed for SARS transmission from Civets to Humans. In fact, in those SARS strains which were determined to be most infectious, the unfavorable electrostatic interactions at the binding interface were removed via mutations at the critical residues 479 and 487. [16] In 2020 Zhou et al. (Nature. 2020; 579: 270-273) and Hoffmann et al. (Cell. 2020; 181: 271-280) showed that SARS-CoV-2, the COVID-19 coronavirus causing the global 2019-2020 pandemia, uses ACE2 as a receptor protein to enter and infect cells, just as SARS-CoV does. Cell entry requires the binding of the S1 region of the virus spike (S) protein to ACE2 followed by the fusion of the viral and cellular membranes produced by the S2 subunit of the S protein. Beforehand, this process requires priming of the S protein by host cell proteases, which is performed by TMPRSS2 and the endosomal cysteine proteases cathepsin B and L (CatB/L). ...
Cathepsin B is a lysosomal cysteine protease, which is involved in the degradation of the extracellular matrix in tumor growth. It has been investigated in various carcinomas of the gastrointestinal tract, lung, breast, and others. Correlations with clinico-pathological variables and a worse prognosis associated with a strong expression of cathepsin B have been observed in some studies. However, in gastric cancer, previous results were contradictory. In the present immunohistochemical study, gastric adenocarcinomas from 115 patients were included. All patients were treated by gastrectomy with D2 lymphadenectomy. 49 patients were women (42.6 %) and 66 (57.4 %) were men. The mean age was 64.4 years (range: 33 - 85). All carcinomas were classified according to the UICC, WHO, Laur n, Goseki and Ming classification. Formalin-fixed and paraffin-embedded specimens were immunohistochemically stained according to a standard ABC peroxidase method. The extent of immunoreactivity was scored ...
1CPJ: Crystal structures of recombinant rat cathepsin B and a cathepsin B-inhibitor complex. Implications for structure-based inhibitor design.
Cathepsin B is an enzymatic protein belonging to the peptidase (or protease) families. In humans, it is coded by the CTSB gene. The protein encoded by this gene is a lysosomal cysteine protease composed of a dimer of disulfide-linked heavy and light chains, both produced from a single protein precursor. It is a member of the peptidase C1 family. At least five transcript variants encoding the same protein have been found for this gene.

OBJECTIVE To measure the cardiovascular threat of diabetic subject matter with chronic kidney disease (CKD) predicated on different approximated glomerular filtration rate (eGFR) equations also to evaluate which definition of CKD best improves cardiovascular risk prediction from the Framingham Cardiovascular Risk Score (Framingham-CV-RS). Outcomes During 5 many years of follow-up, 95 people had a major cardiovascular event. Crude HRs had been increased for many CKD definitions. Nevertheless, after CI-1040 modifying for founded cardiovascular risk elements, HRs for both creatinine-based CKD meanings had been attenuated to stage estimates of just one 1.03, whereas the HRs for the cystatin CCbased CKD description continued to be significantly increased (HR 1.75 [95% CI 1.07C2.87]). Expansion of the research model by the various CKD definitions led to a rise in the statistic only once SCKL adding CKD-CysC (from 0.638 to 0.644) plus a net CI-1040 reclassification improvement of 8.9%.

We develop a simple fluorescence method for the sensitive detection of cathepsin B activity based on the integration of a peptide-DNA conjugate with multiple cyclic signal amplification. This method can detect cathepsin B activity with an extremely low detection limit of 8.1 × 10⁻¹² g mL⁻¹ and a large dynamic range of 4 orders of magnitude from 1 × 10⁻¹¹ to 1 × 10⁻⁷ g mL⁻¹, and it can even measure ...

The conserved oligomeric complex (COG) is a multi-subunit vesicle tethering complex that functions in retrograde trafficking at the Golgi. We have previously demonstrated that the formation of enlarged endo-lysosomal structures (EELSs) is one of the major glycosylation-independent phenotypes of cells depleted for individual COG complex subunits. Here, we characterize the EELSs in HEK293T cells using microscopy and biochemical approaches. Our analysis revealed that the EELSs are highly acidic and that vATPase-dependent acidification is essential for the maintenance of this enlarged compartment. The EELSs are accessible to both trans-Golgi enzymes and endocytic cargo. Moreover, the EELSs specifically accumulate endolysosomal proteins Lamp2, CD63, Rab7, Rab9, Rab39, Vamp7, and STX8 on their surface. The EELSs are distinct from lysosomes and do not accumulate active Cathepsin B. Retention using selective hooks (RUSH) experiments revealed that biosynthetic cargo mCherry-Lampl reaches the EELSs much ...

Nanomaterials are being incorporated into many biological applications for use as therapeutics sensors or labels. silver nanoparticles due to the increased use of these materials in biological applications. This manuscript depicts how both of these types of nanomaterials affect cathepsin activity which could impact the hosts immune system and its ability to respond to pathogens. Cathepsin B activity decreases in a dose-dependent manner with all nanoparticles tested. Alternatively the impact of nanoparticles on cathepsin L activity depends greatly on the type and size of the material. ≤ 0.05 was used as the level for significance.

Inhalation of silica crystals causes inflammation in the alveolar space. Prolonged exposure to silica can lead to the development of silicosis, an irreversible, fibrotic pulmonary disease. The mechanisms by which silica and other crystals activate immune cells are not well understood. Here we demonstrate that silica and aluminum salt crystals activated inflammasomes formed by the cytoplasmic receptor NALP3. NALP3 activation required phagocytosis of crystals, and this uptake subsequently led to lysosomal damage and rupture. Sterile lysosomal damage (without crystals) also induced NALP3 activation, and inhibition of either phagosomal acidification or cathepsin B activity impaired NALP3 activation. Our results indicate that the NALP3 inflammasome senses lysosomal damage as an endogenous danger signal.

IL-13 dysregulation plays a critical role in the pathogenesis of a variety of inflammatory and remodeling diseases. In these settings, STAT6 is believed to be the canonical signaling molecule mediating the tissue effects of IL-13. Signaling cascades involving MAPKs have been linked to inflammation and remodeling. We hypothesized that MAPKs play critical roles in effector responses induced by IL-13 in the lung. We found that Tg IL-13 expression in the lung led to potent activation of ERK1/2 but not JNK1/2 or p38. ERK1/2 activation also occurred in mice with null mutations of STAT6. Systemic administration of the MAPK/ERK kinase 1 (MEK1) inhibitor PD98059 or use of Tg mice in which a dominant-negative MEK1 construct was expressed inhibited IL-13-induced inflammation and alveolar remodeling. There were associated decreases in IL-13-induced chemokines (MIP-1α/CCL-3, MIP-1β/CCL-4, MIP-2/CXCL-1, RANTES/CCL-5), MMP-2, -9, -12, and -14, and cathepsin B and increased levels of α1-antitrypsin. ...
Traditional mouse models of cancer rely primarily on ex vivo measurements of disease morphology and histologic analysis for the assessment of tumors. These measurements of disease may be distant from the actual biological targets of interest and can be time consuming, expensive, and impractical. By using NIR (Near-Infrared) in vivo imaging probes in combination with FMT, the biological processes that change with disease progression and therapeutic response can be visualized non-invasively over time.. ProSense™ agents were developed to specifically look at the expression and activity of key disease associated proteases. ProSense agents are optically silent until in the presence of these proteases and can be used to easily monitor the activity of these proteases in real time. PerkinElmer offers three different ProSense activatable agents. ProSense 680 is activated by Cathepsin B, L, S and Plasmin. ProSense 750 FAST is activated by Cathepsin B, L, S, K, V and D.

Cysteine cathepsin proteases contribute to many normal cellular functions, and their aberrant activity within various cell types can contribute to many diseases, including breast cancer. It is now well accepted that cathepsin proteases have numerous cell-specific functions within the tumor microenvironment that function to promote tumor growth and invasion, such that they may be valid targets for anti-metastatic therapeutic approaches. Using activity-based probes, we have examined the activity and expression of cysteine cathepsins in a mouse model of breast cancer metastasis to bone. In mice bearing highly metastatic tumors, we detected abundant cysteine cathepsin expression and activity in myeloid-derived suppressor cells (MDSCs). These immature immune cells have known metastasis-promoting roles, including immunosuppression and osteoclastogenesis, and we assessed the contribution of cysteine cathepsins to these functions. Blocking cysteine cathepsin activity with multiple small-molecule ...
Purpose : We have previously demonstrated that an accumulation of advanced glycation end-products (AGEs) in the Bruchs membrane (BrM) can alter retinal pigment epithelium (RPE) lysosomal activity by changing expression of key effectors and inhibitors. Altered activity of lysosomal cysteine proteases, the cathepsins, can in turn impact signalling via the NF-kB pathway. The aim of this study therefore was to analyse the effects of AGEs on specific lysosomal cathepsins, and the endogenous levels of effectors of the NF-kB signalling pathway in RPE. Methods : ARPE-19 cells were cultured on AGE-containing BrM mimics in vitro for 7-14 days. Intracellular processing of the cysteine proteases cathepsins B, L and S were assessed by qPCR and immunoblotting, while their intracellular activity was assessed using fluorescence-based cleavage assays. Expression of NF-kB (p65) and its main regulatory protein, IκBα, was assessed by qPCR and immunoblotting. Statistical analysis was performed using the ...
Cathepsins in general are of interest to parasitologists, as there is considerable evidence that they play a key role in the biology of parasites [29]. In this study, a CB of C. sinensis was cloned and overexpressed in E. coli. It was classified as CB due to its sequence homology to cathepsin B protein and structure. The putative amino acid sequence shared 63%, 52% and 50% identities with cathepsin B from S. japonicum, H. sapiens and F. hepatica, respectively. Sequence analysis showed that Cs CB has typical catalytic residue of cysteine, histidine and asparagine, as well an occluding loop that is the signature of cathepsin Bs [30]. A haemoglobinase motif which is shared by helminth blood-feeders could be found in this deduced sequence [31]. Since C. sinensis generally feed on bile and epithelial cells rather than blood, however, it is thought that this motif may be an important tool for identifying potential hemoglobinases and contribute to haemoglobin degradation [32]. The occluding loop is a ...
1. L-trans-Epoxysuccinyl-leucylamido(4-guanidino)butane (E-64) at a concentration of 0.5 mM had no effect on the serine proteinases plasma kallikrein and leucocyte elastase or the metalloproteinases thermolysin and clostridial collagenase. In contrast, 10 muM-E-64 rapidly inactivated the cysteine proteinases cathepsins B, H and L and papain (t0.5 = 0.1-17.3s). The streptococcal cysteine proteinase reacted much more slowly, and there was no irreversible inactivation of clostripain. The cysteine-dependent exopeptidase dipeptidyl peptidase I was very slowly inactivated by E-64. 2. the active-site-directed nature of the interaction of cathepsin B and papain with E-64 was established by protection of the enzyme in the presence of the reversible competitive inhibitor leupeptin and by the stereospecificity for inhibition by the L as opposed to the D compound. 3. It was shown that the rapid stoichiometric reaction of the cysteine proteinases related to papain can be used to determine the operational molarity of
Complexes of gold( I) have long been used to treat rheumatoid arthritis although the precise biological targets of gold are not well understood. One intriguing therapeutic target of Au( I) is the cathepsin family of lysosomal cysteine proteases. Here, we present the inhibition of cathepsin B by a known Au( I)-based drug and a series of derivatives. The complexes investigated were reversible, competitive inhibitors with IC50 values ranging from 0.3 to 250 mu M, depending on the substituents around the Au( I). ...

The GMRI has previously demonstrated the putative presence of two cancer stem cell (CSC) subpopulations within moderately differentiated oral tongue squamous cell carcinoma (MDOTSCC), which express components of the renin-angiotensin system (RAS).. In this study we investigated the expression and localisation of the proteases cathepsins B, D, and G in relation to these CSC subpopulations within MDOTSCC.. We identified the presence of cathepsins B and D in the CSCs and cathepsin G on what are phenotypically mast cells. The identification of these suggests the presence of bypass loops for the RAS. Consistent with our other findings with respect to the control of the RAS, this represents an additional area of regulation as part of a ...

l-Asparaginase is a key therapeutic agent for treatment of childhood acute lymphoblastic leukemia (ALL). There is wide individual variation in pharmacokinetics, and little is known about its metabolism. The mechanisms of therapeutic failure with l-asparaginase remain speculative. Here, we now report that 2 lysosomal cysteine proteases present in lymphoblasts are able to degrade l-asparaginase. Cathepsin B (CTSB), which is produced constitutively by normal and leukemic cells, degraded asparaginase produced by Escherichia coli (ASNase) and Erwinia chrysanthemi. Asparaginyl endopeptidase (AEP), which is overexpressed predominantly in high-risk subsets of ALL, specifically degraded ASNase. AEP thereby destroys ASNase activity and may also potentiate antigen processing, leading to allergic reactions. Using AEP-mediated cleavage sequences, we modeled the effects of the protease on ASNase and created a number of recombinant ASNase products. The N24 residue on the flexible active loop was identified as ...
A team of scientists from the University of California, San Diego School of Medicine, the Medical University of South Carolina and San Diego-based American Life Science Pharmaceuticals, Inc., report that cathepsin B gene knockout or its reduction by an enzyme inhibitor blocks creation of key neurotoxic pGlu-Aβ peptides linked to Alzheimers disease. Moreover, the candidate inhibitor drug has been shown to be safe in humans.
