Abstract
Background Presently, no study reported the function of cathepsin H (CTSH) in thyroid carcinoma (THCA). The aim of present study was to initially explore the factors affecting CTSH expression, and association between CTSH expression and survival rate in THCA. Methods We explored mRNA expression of CTSH in normal and BRCA tissues, and evaluated prognostic impact of CTSH expression on the overall survival of THCA patients. Then, related factors influencing CTSH mRNA expression in THCA were analyzed. Functional enrichment analysis was performed to reveal the potential function of CTSH involved in THCA. We also constructed PPI network among co-expressed genes of CTSH to determine hub genes, followed by association analysis on hub genes with CTSH. Results (1) CTSH mRNA was highly expressed in THCA compared with normal group (P<0.001). High expression of CTSH was conducive to the overall survival of THCA patients (P=0.0027). CTSH was then determined as an independent prognostic factor in THCA (P=0.024). (2) The mRNA expression of CTSH was statistically related to patient’s histological type, N stage, T stage, tumor stage and sample type (all P<0.001). CTSH copy number variation and methylation also influenced its mRNA expression (all P<0.001). (3) Pathway analysis indicated that CTSH mainly participated in cancer-related pathways, such as hedgehog signaling pathway, cytokine–cytokine receptor interaction and JAK-STAT signaling pathway (all P<0.05). (4) The top 10 co-expressed genes in whole PPI network showed significant correlation with CTSH expression (all P<0.001). Conclusion CTSH higher expression was observed in THCA, which caused a good prognosis of patients. CTSH expression might be regulated by multiple factors including clinical characteristic, methylation, copy number and other genes. This study demonstrated the clinical significance of CTSH in THCA, as well as revealed the potential pathway associated with CTSH involved in thyroid cancer.

Cancer Cell-Derived Matrisome Proteins Promote Metastasis in Pancreatic Ductal Adenocarcinoma. Cancer Res 2020; 80:1461-1474. [PMID: 32029550 PMCID: PMC7127978 DOI: 10.1158/0008-5472.can-19-2578] [Citation(s) in RCA: 86] [Impact Index Per Article: 21.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2019] [Revised: 12/20/2019] [Accepted: 01/30/2020] [Indexed: 12/23/2022]
Abstract
The prognosis for pancreatic ductal adenocarcinoma (PDAC) remains poor despite decades of effort. The abundant extracellular matrix (ECM) in PDAC comprises a major fraction of the tumor mass and plays various roles in promoting resistance to therapies. However, nonselective depletion of ECM has led to poor patient outcomes. Consistent with that observation, we previously showed that individual matrisome proteins derived from stromal cells correlate with either long or short patient survival. In marked contrast, those derived from cancer cells correlate strongly with poor survival. Here, we studied three cancer cell-derived matrisome proteins that are significantly overrepresented during PDAC progression, AGRN (agrin), SERPINB5 (serine protease inhibitor B5), and CSTB (cystatin B). Using both overexpression and knockdown experiments, we demonstrate that all three are promoters of PDAC metastasis. Furthermore, these proteins operate at different metastatic steps. AGRN promoted epithelial-to-mesenchymal transition in primary tumors, whereas SERPINB5 and CSTB enhanced late steps in the metastatic cascade by elevating invadopodia formation and in vivo extravasation. All three genes were associated with a poor prognosis in human patients and high levels of SERPINB5, secreted by cancer cells and deposited in the ECM, correlated with poor patient prognosis. This study provides strong evidence that cancer cell-derived matrisome proteins can be causal in promoting tumorigenesis and metastasis and lead to poor patient survival. Therefore, compared with the bulk matrix, mostly made by stromal cells, precise interventions targeting cancer cell-derived matrisome proteins, such as AGRN, SERPINB5, and CSTB, may represent preferred potential therapeutic targets. SIGNIFICANCE: This study provides insights into the biological roles of cancer cell-derived matrisome proteins in PDAC and supports the notion that these proteins are protumorigenic and better therapeutic targets.

Cystatins in cancer progression: More than just cathepsin inhibitors. Biochimie 2019; 166:233-250.

Abstract
Cystatins are endogenous and reversible inhibitors of cysteine peptidases that are important players in cancer progression. Besides their primary role as regulators of cysteine peptidase activity, cystatins are involved in cancer development and progression through proteolysis-independent mechanisms. Mechanistic studies of cystatin function revealed that they affect all stages of cancer progression including tumor growth, apoptosis, invasion, metastasis and angiogenesis. Recently, the involvement of cystatins in the antitumor immune responses was reported. In this review, we discuss molecular mechanisms and clinical aspects of cystatins in cancer. Altered expression of cystatins in cancer resulting in harmful excessive cysteine peptidase activity has been a subject of several studies in order to find correlations with clinical outcome and therapy response. However, involvement in anti-tumor immune response and signaling cascades leading to cancer progression designates cystatins as possible targets for development of new anti-tumor drugs.

Abstract
Cysteine cathepsins (CTS), being involved in both physiological and pathological processes, play an important role in the human body. During the last 30 years, it has been shown that CTS are highly upregulated in a wide variety of cancer types although they have received a little attention as a potential therapeutic target as compared to serine or metalloproteinases. Studies on the increasing problem of neoplastic progression have revealed that secretion of cell-surface- and intracellular cysteine proteases is aberrant in tumor cells and has an impact on their growth, invasion, and metastasis by taking part in tumor angiogenesis, in apoptosis, and in events of inflammatory and immune responses. Considering the role of CTS in carcinogenesis, inhibition of these enzymes becomes an attractive strategy for cancer therapy. The downregulation of natural CTS inhibitors (CTSsis), such as cystatins, observed in various types of cancer, supports this claim. The intention of this review is to highlight the relationship of CTS with cancer and to present illustrations that explain how some of their inhibitors affect processes related to neoplastic progression.

Proteolytic Profile of Cysteine Proteases and Inhibitors Determines Tumor Cell Phenotype in Squamous Cell Carcinoma of the Head and Neck. Int J Biol Markers 2018; 26:247-54.

Abstract
The hypothesis was tested that a specific pattern in the cysteine cathepsin/inhibitor ratio is associated with the development of more aggressive tumor cell phenotypes in squamous cell carcinoma of the head and neck (SCCHN). For this purpose commercially available ELISAs were used to determine the concentrations of cysteine cathepsins B and L and their inhibitors, stefins A and B, in cytosols of nontumorous mucosa and primary tumors from 92 patients. Using the stefin A concentration difference in matched pairs of tissue samples as a stratifying variable, 53 cases were found to be upregulated (higher concentrations in tumor samples than in nontumorous mucosa) and 39 cases downregulated. Disease recurrence was more frequent in the downregulated group than in the upregulated group (35.9% vs 11.3%, p=0.009), which resulted in significantly different 5-year disease-free survival rates (61.2% vs 88%, p=0.004). The consistency of these results was confirmed by repeating the analysis in an independent group of patients (the reference group). The presented results suggest that in patients with SCCHN, specific patterns in the proteolytic profile of cysteine proteases and their inhibitors are associated with the development of distinctly aggressive tumor cell phenotypes and are of prognostic value.

Abstract
The expression levels and the prognostic impact of urokinase-type plasminogen activator (uPA) and cathepsin D (CD) were evaluated in patients with locally advanced laryngeal squamous cell carcinoma (LSCC). uPA and CD protein levels were determined by immunoluminometric or immunoenzymatic assays in the cytosol of paired sets of tumor tissues and corresponding adjacent normal mucosa (NLM) from 57 patients with stage III/IV LSCC and were correlated with a number of clinicobiological parameters of this tumor including anatomical site, tumor grade, nodal status, clinical stage, DNA ploidy, proliferation rate, and patient outcome. Median uPA levels were significantly higher in LSCC than in NLM (1.8 ng/mg of protein vs 0.3 ng/mg; p<0.001) whereas median CD levels were not significantly increased in tumor tissue compared to NLM (24 pmol/mg vs 19 pmol/mg, p=0.063). No significant correlation was observed between uPA and CD concentrations in tumor tissues (r=-0.1; p=0.4). Furthermore, the distribution analysis of uPA and CD in tumors showed no correlation between expression levels of these proteinases and the parameters mentioned above including patient outcome. However, when data were matched according to each parameter examined it was observed that the differences in uPA content between LSCC and NLM, expressed as uPA tumor/normal tissue ratio (T/M), were more marked in clinically advanced and/or aggressive forms of LSCC (i.e., node positive, stage IV, poorly and moderately differentated, aneuploid multiclonal, low S-phase, subglottis tumors). These data suggest that in such tumors altered regulation of uPA may occur to a greater extent than in less aggressive and less advanced forms of LSCC. This phenomenon was not observed for CD. However, in tumors with a high proliferation rate, in stage IV tumors as well as in those located in the supraglottis, CD levels were significantly higher than those found in the corresponding NLM (p=0.008, p=0.02 and p=0.03, respectively). In conclusion, uPA is highly expressed in locally advanced LSCC and appears to be implicated in some key events of progression of this tumor such as local invasion and/or nodal involvement, whereas CD does not seem to have a role in promoting these processes. Nevetheless, neither of these proteinases seem to be prognostically useful in patients with stage III/IV tumors.

Abstract
Cathepsin H is a lysosomal cysteine protease that may participate in tumor progression. In order to evaluate its potential as a prognostic marker, its protein levels were measured by ELISA in preoperative sera from 324 patients with colorectal cancer. The level of cathepsin H was significantly increased in patient sera, the median level was 8.4 ng/mL versus 2.1 ng/mL in 90 healthy blood donors (p<0.0001). A weak association of cathepsin H levels was found with patient age (p=0.02) but not with Dukes’ stage, sex, or the level of carcinoembryonic antigen (CEA). In survival analysis a significant difference was found between the group of patients with low cathepsin H (first tertile) who had a poor prognosis and the remaining patients (p=0.03). The risk of patients was further stratified when cathepsin H levels were combined with CEA. Patients with high CEA and low cathepsin H had the highest risk of death with a hazard ratio of 2.72 (95% CI 1.73–4.28), p<.0001. Our results show that the prognostic information of cathepsin H differs from that of the related cathepsins B and L and suggest different roles during the progression of malignant disease.

Abstract
Cysteine cathepsin protease activity is frequently dysregulated in the context of neoplastic transformation. Increased activity and aberrant localization of proteases within the tumour microenvironment have a potent role in driving cancer progression, proliferation, invasion and metastasis. Recent studies have also uncovered functions for cathepsins in the suppression of the response to therapeutic intervention in various malignancies. However, cathepsins can be either tumour promoting or tumour suppressive depending on the context, which emphasizes the importance of rigorous in vivo analyses to ascertain function. Here, we review the basic research and clinical findings that underlie the roles of cathepsins in cancer, and provide a roadmap for the rational integration of cathepsin-targeting agents into clinical treatment.

Abstract
Three bio macromolecules cathepsins B, H and L of physiological and pathological significance have been selected for the study. The molecules have been designed by combining two important pharmacophores their cyclized analogues and were studied for their inhibitory effects on selected enzymes. Two isomeric forms of chalconesemicarbazones are reported for the first time. The synthesized compounds showed a competitive inhibition towards cathepsins B, H and L. Docking experiments were run along with to relate with in vitro studies.
Cathepsin B [EC 3.4.22.1], cathepsin H [EC 3.4.22.16] and cathepsin L [EC 3.4.22.15] are the most versatile lysosomal cysteine proteases and are responsible for intracellular protein degradation. These are involved in a number of pathological conditions including tissue degenerative processes. In the present work, we report the synthesis and systematic evaluation of differently substituted chalcones, chalconesemicarbazones, and diarylpyrazolines on cathepsins B, H and L activity. It was found that after a preliminary screening as cysteine protease inhibitors, chalconesemicarbazones were better inhibitors to these cysteine proteases than diarylpyrazolines followed by chalcones. All the synthesized compounds were identified as the best inhibitors to cathepsin L followed by cathepsin B and then cathepsin H. The results are compared with docking studies and it was found that all the compounds resulted in decrease in energy while interacting with the active site of the enzyme.

Abstract
Background Cathepsin H is a cysteine protease considered to play a major role in tumor progression, however, its precise function in tumorigenesis is unclear. Cathepsin H was recently proposed to be involved in processing of bone morphogenetic protein 4 (BMP-4) in mice. In order to clarify whether cathepsin H also regulates BMP-4 in humans, its impact on BMP-4 expression, processing and degradation was investigated in prostate cancer (PC-3), osteosarcoma (HOS) and pro-monocytic (U937) human cell lines. Materials and methods BMP-4 expression was founded to be regulated by cathepsin H using PCR array technology and confirmed by real time PCR. Immunoassays including Western blot and confocal microscopy were used to evaluate the influence of cathepsin H on BMP-4 processing. Results In contrast to HOS, the expression of BMP-4 mRNA in U937 and PC3 cells was significantly decreased by cathepsin H. The different regulation of BMP-4 synthesis could be associated with the absence of the mature 28 kDa cathepsin H form in HOS cells, where only the intermediate 30 kDa form was observed. No co-localization of BMP-4 and cathepsin H was observed in human cell lines and the multistep processing of BMP-4 was not altered in the presence of specific cathepsin H inhibitor. Isolated cathepsin H does not cleave mature recombinant BMP-4, neither with its amino- nor its endopeptidase activity. Conclusions Our results exclude direct proteolytic processing of BMP-4 by cathepsin H, however, they provide support for its involvement in the regulation of BMP-4 expression.

Abstract
Head and neck squamous cell carcinoma (HNSCC) is the sixth most common cancer worldwide. Although considerable progress has been made in elucidating the etiology of the disease, the prognosis for individuals diagnosed with HNSCC remains poor, underscoring the need for development of additional treatment modalities. HNSCC is characterized by the upregulation of a large number of proteolytic enzymes, including urokinase plasminogen activator (uPA) and an assortment of matrix metalloproteinases (MMPs) that may be expressed by tumor cells, by tumor-supporting stromal cells or by both. Here we explored the use of an intercomplementing anthrax toxin that requires combined cell surface uPA and MMP activities for cellular intoxication and specifically targets the ERK/MAPK pathway for the treatment of HNSCC. We found that this toxin displayed strong systemic anti-tumor activity towards a variety of xenografted human HNSCC cell lines by inducing apoptotic and necrotic tumor cell death, and by impairing tumor cell proliferation and angiogenesis. Interestingly, the human HNSCC cell lines were insensitive to the intercomplementing toxin when cultured ex vivo, suggesting that either the toxin targets the tumor-supporting stromal cell compartment or that the tumor cell requirement for ERK/MAPK signaling differs in vivo and ex vivo. This intercomplementing toxin warrants further investigation as an anti-HNSCC agent.

Abstract
Proteases can regulate many aspects of tumor development as their actions, which include degradation of the extracellular matrix, proteolytic processing of chemokines and activation of other enzymes, influence several key tumorigenic processes. Members of one protease class, the cysteine cathepsins, have received increasing recognition for their involvement in cancer development, and numerous clinical studies have reported correlations between elevated cathepsin levels and malignant progression. This is also the case for cathepsin H, a member of the cysteine cathepsin family, and its utility as a prognostic marker has been analyzed extensively. However, there is limited information available on its specific functions in tumor development and progression. To gain further insight into the role of this protease in cancer, we crossed cathepsin H-deficient mice with the RIP1-Tag2 model of pancreatic islet carcinogenesis. Deletion of cathepsin H significantly impaired angiogenic switching of the pre-malignant hyperplastic islets and resulted in a reduction in the subsequent number of tumors that formed. Moreover, the tumor burden in cathepsin H null RT2 mice was significantly reduced, in association with defects in the blood vasculature and increased apoptosis. Thus, we demonstrate here for the first time important tumor-promoting roles for cathepsin H in vivo using a mouse model of human cancer.

Abstract
Cystatin C is a low-molecular-weight protein which has been proposed as a marker of renal function that could replace creatinine. Indeed, the concentration of cystatin C is mainly determined by glomerular filtration and is particularly of interest in clinical settings where the relationship between creatinine production and muscle mass impairs the clinical performance of creatinine. Since the last decade, numerous studies have evaluated its potential use in measuring renal function in various populations. More recently, other potential developments for its clinical use have emerged. This review summarises current knowledge about the physiology of cystatin C and about its use as a renal marker, either alone or in equations developed to estimate the glomerular filtration rate. This paper also reviews recent data about the other applications of cystatin C, particularly in cardiology, oncology and clinical pharmacology.

Abstract
PURPOSE Patient survival after resection of non-small cell lung cancer (NSCLC) strongly correlated with the occurrence of distant metastasis. Cathepsins are members of the lysosomal cysteine proteases family and can support the metastatic process by degrading the extracellular matrix. The purpose of this study was to identify members of the Cathepsin family that correlate with recurrence-free and overall survival of NSCLC patients. PATIENTS AND METHODS The expression of 13 Cathepsins was examined using DNA-microarray technology in tumor tissues of 89 surgically treated NSCLC patients. All NSCLC samples were classified according to median Cathepsin expression value into either a high or a low expression group. All Cathepsin expression groups were subjected to clinical prognostic analyses regarding survival and local as well as distant recurrences. RESULTS Patients with high Cathepsin C tumor expression showed higher tumor recurrence rate compared to patients with low Cathepsin C expression (p = 0.02). The tumor expression of Cathepsins K and B significantly correlated with recurrence-free and overall survival as determined by multivariate analysis. A high expression of Cathepsin B or K was associated with a considerable reduction of recurrence-free as well as overall survival. NSCLC patients with a high expression of both Cathepsin B and K had a significantly (p = 0.001) poorer outcome (5-year survival rate: 13%) than patients with low expression of both genes (5-year survival rate: 75%). CONCLUSIONS The combined expression level of Cathepsins B and K identifies high-risk NSCLC patients. A selection of gene expression panels is theoretically superior to established clinical and pathological criteria.

Abstract
After a finite number of population doublings, normal human cells undergo replicative senescence accompanied by growth arrest. We previously described a model of stress-induced premature senescence by treatment of dermal fibroblasts with psoralen plus UVA, a common photodermatological therapy. Psoralen photoactivation has long been used as a therapy for hyperproliferative skin disorders. The repetitive therapeutical treatment is accompanied by premature aging of the skin. Treatment of fibroblasts in vitro with 8-methoxypsoralen (8-MOP) and subsequent ultraviolet A (UVA) irradiation results in growth arrest with morphological and functional changes reminiscent of replicative senescence. For gene expression profiling in two strains of human skin fibroblasts after PUVA treatment, we used a low-density DNA array representing 240 genes involved in senescence and stress response. Twenty-nine genes were differentially expressed after PUVA treatment in the two strains of human skin fibroblasts. These genes are involved in growth arrest, stress response, modification of the extracellular matrix and senescence. This study contributes further to the elucidation of the PUVA model and its validation as a useful stress-induced premature senescence model aiming to characterize the premature senescence of fibroblasts and to identify biomarkers that could be applied in vivo.

Abstract
PURPOSE The aim of this study was to test the hypothesis about the protective role of high stefin A and stefin B concentrations in operable carcinoma of the head and neck. METHODS AND MATERIALS Stefins A and B concentrations were measured in tissue cytosols of nontumorous mucosa and primary tumors from 92 patients. For quantitative analysis of stefins in tumor cytosols, commercially available enzyme-linked immunosorbent assays were used. RESULTS Stefin A was upregulated in 53 patients (higher concentrations were measured in tumor samples than in nontumorous mucosa) and was downregulated in 39 patients. The corresponding numbers for stefin B were 49 and 43, respectively. A significantly higher proportion of downregulated cases were found among patients with disease re-appearance. In the Cox model, high stefin A concentrations appeared as independent predictors for favorable disease-free survival. Assuming a "broken stick" model, a significant increase in the recurrence rate after the threshold of 1063 ng/mgp (the 64th percentile in the group) was found, the hazard ratio reaching 3% of the reference value with doubling of the level of stefin A. These results were reconfirmed after pooling the data with two historical data sets into a uniform series involving 182 patients. CONCLUSIONS A group of patients at high risk for disease progression was identified, characterized by the downregulated stefin A protein in the tumor compared with the nontumorous mucosa. Stefin A was recognized as a promising candidate marker for prognosis in patients with operable carcinoma of the head and neck.

Abstract
Squamous cell cancer in the head and neck region (HNSC) is unique concerning its progression since it remains locoregional for long time and visceral metastases develop only in a later stage of the disease. Accordingly, molecular markers of the local invasion and the lymphatic dissemination both have critical importance. HNSC progression is associated with deregulated control of cell proliferation and apoptosis but it seems equally significant the disregulation of the proteolytic machineries. Here we outline the lymphatic metastatic cascade for HNSC to depict key molecular determinants as possible prognostic factors or therapeutic targets identifying immunological selection as a major feature. Unlike in local spreading, invasive potential of cancer cells seems to be less significant during lymphatic dissemination due to the anatomical properties of the lymphatic vessels and tissues. There is a general believe that HNSC is one disease however, data indicate that the anatomical localization of the tumor (the "soil") such as oral, lingual, glottic or pharyngeal has a significant effect on the gene expression profile and corresponding biological behavior of HNSC. Furthermore, even the endocrine milieu of the host was proved to be influential in modulating the progression of HNSC. Gene expression profiling techniques combined with proteomics could help to define and select usefull genetic and biomarkers of progression of HNSC, some of them could well be potential novel therapeutic target.

Abstract
BACKGROUND Cathepsin B, a lysosomal cysteine protease, has a major role in the mechanisms of tumor metastasis. The aim of the present work was to examine the correlation between cathepsin B activity and the metastatic potential of human pancreatic cancer. METHODS The primary cell line COLO 357 and the derivative tumor cell lines FG, L3.1, L3.2, L3.3, L3.4, and L3.5, which are characterized by progressively increasing metastatic potential, were injected intrasplenically in the athymic mice. Cathepsin B activity, metastasis, and ultrastructural characteristics were assessed. RESULTS An increased number of liver tumor nodules was observed with each subsequent intrasplenic inoculation (p = 0.001), associated with lymph node, splenic, and pancreatic involvement. Cathepsin B activity progressively increased (p = 0.001) and was strongly positively correlated with the metastatic potential. However, no correlation was found between the metastatic potential and ultrastructural characteristics. CONCLUSIONS These findings further support the central role of cathepsin B in metastasis in a combined in vitro/in vivo model.

Abstract
OBJECTIVES It has been shown that the expression of the lysosomal proteolytic enzymes cathepsin B, H, and L (CB, CH, and CL, respectively) correlate with tumor progression in various neoplasms. However, no data are available in cell lysates and supernatants of differently differentiated human bladder cell lines or in noncancerous and cancerous bladder tissue. METHODS Using spectrofluorometric assays, catalytic activities of CB, CH, CL, and their inhibitor (CIP) were measured both in differently differentiated human bladder cell lines (HCV29, normal; RT4, well differentiated; J82, poorly differentiated) and in noncancerous and cancerous tissue samples (n = 20) of transitional cell carcinoma obtained from transurethral resections of the bladder or cystectomies. Enzyme activities were related to the protein content in tissue samples or to the cell count in cell lines. RESULTS In comparison to the intracellular activities of CB, CH, and CL in the poorly differentiated cell line J82, the intracellular activities in the normal cell line HCV29 were significantly greater (P <0.05), independent of stage or grade. In contrast, the portion of cathepsins released from cell line J82 into the supernatant revealed higher values than that from cell line HCV29. In cancerous bladder tissue, CB and CH were significantly greater than in the matched normal tissue (P <0.05). CL and CIP did not show any statistically significant differences. CONCLUSIONS Increased cathepsin concentrations in the supernatant of the poorly differentiated J82 carcinoma cell culture, as well as in cancerous bladder tissue, are indicative of a proteolytic imbalance and potential indicators of bladder cancer.

Abstract
This review comprises issues concerning cysteine cathepsins (CCs): human peptidases belonging to papain family (C1) of clan CA of cysteine proteases: cathepsins B, L, H, S, K, F, V, X, W, O and C. The involvement of these enzymes in physiological and pathological processes is described, especially with respect to their application as diagnostic and prognostic markers. They participate in precursor protein activation (including proenzymes and prohormones), MHC-II-mediated antigen presentation, bone remodeling, keratinocytes differentiation, hair follicle cycle, reproduction and apoptosis. Cysteine cathepsins upregulation has been demonstrated in many human tumors, including breast, lung, brain, gastrointestinal, head and neck cancer, and melanoma. Besides cancer diseases, they have been implied to participate in inflammatory diseases, such as inflammatory myopathies, rheumatoid arthritis, and periodontitis. Also, certain hereditary disorders are connected with mutations in CCs genes, what is observed in pycnodysostosis resulted from catK gene mutation and Papillon-Lefevre and Haim-Munk syndrome caused by catC gene defect. The potential application of cysteine cathepsins in diagnosis and/or prognosis is discussed in cancer diseases (breast, lung, head and neck, ovarian, gastrointestinal cancers, melanoma), as well as other disorders (periodontitis, rheumatoid arthritis, osteoarthritis).

Abstract
Although an important risk factor for oral cancer is the presence of epithelial dysplasia, most of these lesions will not progress to malignancy. Presently, for the individual patient with dysplasia, there are few reliable markers that may indicate the likelihood of progression to oral cancer. Cathepsin L is a lysosomal protease that degrades extracellular matrix material. Because cathepsin L is frequently overexpressed in oral squamous cell carcinoma (SCC) we hypothesized that it is also overexpressed in oral premalignancy and that premalignant lesions that progressed to oral cancer expressed higher levels of cathepsin L than those premalignant lesions that did not. In this retrospective pilot study we examined changes in cathepsin L expression at the mRNA level using quantitative TaqMan RT-PCR and at the protein level by immunohistochemistry in 33 routinely processed oral dysplastic lesions and 14 SCCs obtained from 33 patients. Sixteen of the dysplastic lesions progressed to oral SCC and 17 did not after several years of follow-up. Cathepsin L mRNA was overexpressed in 16/33 (48%) dysplastic lesions and in 9/14 (64%) oral SCC. Cathepsin L protein was also overexpressed in a large proportion of dysplasias and cancers. Overexpression was independent of dysplasia grade and identified in both those patients who progressed to oral SCC and in those who did not. Levels of cathepsin L mRNA and protein did not differ significantly in the progressing versus non-progressing dysplasias (P=0.27). However, cathepsin L mRNA and protein were significantly lower in the non-progressing dysplasias when compared to the oral cancers (P=0.03) but not in the progressing dysplasias suggesting a trend for dysplasias with overexpressed cathepsin L to be more likely to progress to oral cancer.

Abstract
The aim of this study was to evaluate the histopathologic features and the expression of angiogenesis-related markers in primary tumors and metastatic lymph nodes of oral squamous cell carcinomas (SCCs) with multiple lymph node involvement in comparison with oral SCCs without nodal metastasis. The protein levels of the angiogenesis inhibitor endostatin, as well as those of the related molecules collagen XVIII, collagen-binding protein (CBP) 2/heat shock protein (HSP) 47, and cathepsin L, were evaluated by immunohistochemical analysis. Compared with nonmetastatic cases, primary tumors of the metastatic group exhibited significantly decreased protein levels of endostatin and its precursor collagen XVIII. Comparison between primary tumors and positive nodes of the metastatic cases revealed decreased expression of collagen XVIII and CBP2/HSP47 in metastases. Angiogenesis is essential for tumor growth and metastasis; accordingly, the observed differences in the immunohistochemical expression of angiogenesis-related proteins in oral SCC with multiple lymph node involvement may provide an explanation for the increased metastatic potential of these tumors.

Abstract
BACKGROUND Cysteine proteases are involved in the extension of cancer into the subarachnoid space. The presence of cathepsins B and H along with their potent inhibitor cystatin C in the cerebrospinal fluid (CSF) was investigated in patients with leptomeningeal metastasis of cancer (LM). MATERIALS AND METHODS CSF samples were obtained in 16 cases of LM (10 solid tumors and 6 leukemia or lymphoma) and compared with 11 cancer cases without involvement of the central nervous system, 12 multiple sclerosis cases and 34 healthy volunteers. The activity of the enzymes was measured, their molecular forms were analyzed by the Western blotting, and the concentration of cystatin C was measured by ELISA. Immunohistochemistry of the leptomeningeal tissues was also performed in six autopsy cases of LM. RESULTS High activities of cathepsins B and H along with decreased cystatin C concentration were observed in CSF of LM as compared with three control groups. Western blot analysis revealed higher concentration of the enzyme protein as well as its active forms in samples with higher enzyme activity. Cells metastasizing leptomeningeal tissue were clearly positive in immunohistochemical staining of cathepsins, indicating active production by tumor cells. CONCLUSION Production of cathepsins B and H by tumor cells and their high activity along with concomitant decrease of their potent inhibitor, cystatin C, in the CSF might contribute in the process of metastasis and spread of the cancer cells in the leptomeningeal tissues. A high enzyme activity/cystatin C concentration ratio in the CSF could be useful when diagnosing LM in combination with other parameters.

Abstract
Increased expression of proteases has been correlated with the malignant progression of a variety of tumors. We found a significant increase in cathepsin H expression in high-grade prostatic intraepithelial neoplasia and carcinoma of the prostate. Two forms of cathepsin H, the full-length form (CTSH) and a truncated form with a 12-amino acid deletion in its signal peptide region (CTSHDelta10-21), were identified by cDNA sequence analysis. This deletion occurred not at the genomic level but likely at the RNA processing level. Both forms are expressed in prostate tissues as well as LNCaP, PC-3, and DU-145 prostate cancer cell lines. The deletion within the signal peptide region affected the trafficking of cathepsin H. Fluorescence microscopy, subcellular fractionation, and activity data indicated that the truncated form was perinuclear and secreted and had a reduced lysosomal association as compared with the full-length cathepsin H. Furthermore, the truncated cathepsin H was enzymatically active. Therefore, an increase in overall cathepsin H expression, particularly in the truncated form with a high secretion propensity, may affect cell biological behaviors such as those associated with tumor progression.

Abstract
OBJECTIVES Cathepsin B, H, and L (CB, CH, CL) are lysosomal proteolytic enzymes that belong to the group of cysteine proteinases. The imbalance between proteinases and their inhibitors is believed to correlate with tumor progression and shortened patient survival. In transitional cell carcinoma (TCC) only limited data have been published. METHODS Using spectrofluorometric assays, catalytic activities of CB, CH, and CL in urine were measured to evaluate the potential diagnostic and prognostic value for patients with TCC of the bladder. Second morning urine was collected and used for measurements. CB, CH, and CL activities were determined for groups of patients with superficial disease (Ta-1, n = 43) and muscle-invasive tumors (T2, n = 18; or greater than T2, n = 9), as well as for different tumor grades (G1, n = 12; G2, n = 26; and G3, n = 31). For comparison, 14 urine samples from patients with bladder inflammation and 43 samples from a control group were also included. RESULTS Compared with the control group, patients with superficial Stage Ta-T1 disease and muscle-invasive Stage T2 or greater disease, as well as patients with G3 tumors, revealed significantly higher urinary CL activity. CB and CH did not show any tumor-related activity increase. CB was significantly lower in patients with nonrecurrent tumors. CONCLUSIONS These results suggest that elevated levels of CL in urine might be indicative of a cellular proteolytic imbalance in TCC of the bladder and may have a prognostic and/or diagnostic value.

Abstract
Cystatin B is unique among cysteine proteinase inhibitors of the cystatin superfamily in having a free Cys in the N-terminal segment of the proteinase binding region. The importance of this residue for inhibition of target proteinases was assessed by studies of the affinity and kinetics of interaction of human and bovine wild-type cystatin B and the Cys 3-to-Ser mutants of the inhibitors with papain and cathepsins L, H, and B. The wild-type forms from the two species had about the same affinity for each proteinase, binding tightly to papain and cathepsin L and more weakly to cathepsins H and B. In general, these affinities were appreciably higher than those reported earlier, perhaps because of irreversible oxidation of Cys 3 in previous work. The Cys-to-Ser mutation resulted in weaker binding of cystatin B to all four proteinases examined, the effect varying with both the proteinase and the species variant of the inhibitor. The affinities of the human inhibitor for papain and cathepsin H were decreased by threefold to fourfold and that for cathepsin B by approximately 20-fold, whereas the reductions in the affinities of the bovine inhibitor for papain and cathepsins H and B were approximately 14-fold, approximately 10-fold and approximately 300-fold, respectively. The decreases in affinity for cathepsin L could not be properly quantified but were greater than threefold. Increased dissociation rate constants were responsible for the weaker binding of both mutants to papain. By contrast, the reduced affinities for cathepsins H and B were due to decreased association rate constants. Cys 3 of both human and bovine cystatin B is thus of appreciable importance for inhibition of cysteine proteinases, in particular cathepsin B.

Abstract
Proteolytic enzymes have been proposed as new biological prognostic indicators to facilitate decisions about treatment of breast cancer patients following surgery. We reported earlier that the activities of cysteine proteinases (CP), cathepsin (Cat) B and cathepsin (Cat) L and the expression of stefin A might be associated with breast tumor progression and prognosis. Here, the protein concentrations of Cats D, B and L and stefin A have been measured in a series of 60 matched pairs of breast tumours and control adjacent tissues, using ELISAs developed in our laboratory. Median tumor concentrations of Cat D (47 pm/mg), Cat B (222 ng/mg) and Cat L (88 ng/mg) were significantly (p<0.0005) increased by 7 fold, 27 fold and 6 fold, respectively. Much greater increases in the activities of Cat B (63 fold) and of Cat L (274 fold) were found, indicating activation of proCat B and proCat L and/or to a decrease in specific endogenous cystatins. However, the 1.6-fold decreased (p<0.0001) levels of inhibition by cystatins could not be entirely responsible for more than 100-fold increased ratio of CP:cystatins activity. Moreover, stefin A was either increased or decreased in tumor samples, resulting in a 1.4-fold median increase in tumors. Comparing the biological parameters with the established histo-pathological prognosticators, we found that the increased protein concentration of Cat B was associated with lymph node involvement (p<0.009) and higher stage (p<0.003), and both Cat B and Cat L activities were more increased in high grade tumours (p<0.05). Survival analysis revealed that stefin A was the most significant prognostic factor for disease-free (p<0.008) and overall survival (p<0.02), followed by increased Cat B activity and protein concentration. Cat L was of borderline significance while Cat D was not significant for prognosis. We conclude that enhanced activation of CP, due partially to an imbalance between cysteine proteinases and inhibitors is linked to the progression of breast cancer. Larger sample size is needed to confirm the prognostic significance of stefin A, Cat B and Cat L.

Abstract
Various recognized prognostic factors in squamous cell carcinoma (SCC) of the larynx influence the therapeutic options offered to an individual patient in order to extend the survival expectancy. Additional prognostic indicators are required in specific patient subgroups. The present study used a standard immunohistochemical technique in order to retrospectively evaluate the accumulation of p53 gene product and the immunoreactivity of bcl-2 protein and cathepsin-D as possible prognostic markers of laryngeal SCC. Formalin-fixed, paraffin-embedded tumor materials were obtained from a series of 64 patients with cancer of the larynx. Immunostaining was evaluated by computerized image analysis. The accumulation of p53 protein was found in 57.8% (37/64) of the patients and was associated with large tumor size. The percentage of p53-positive neoplastic cells increased in high-grade carcinomas, particularly when they simultaneously demonstrated cathepsin-D immunoreaction in stromal cells (P = 0.049); bcl-2 immunoexpression was found to be generally limited. Cathepsin-D immunostaining was observed in tumor parenchymal and stromal cells (31.25% and 37.5% of all cases, respectively); it was found to be useful in defining patient subgroups with differences in relapse-free survival. Among patients with posi-tive lymph nodes, those with cathepsin-D immunopositive tumor cells were at higher risk for relapsing (P = 0.0395). Although the classical prognostic factors of laryngeal carcinoma retain their predominance, cathepsin-D immunoreactivity may serve as an additional prognosticator in specific patient subgroups.

Abstract
BACKGROUND The aspartic proteinase cathepsin D is believed to be associated with proteolytic processes leading to the invasion and seeding of tumor cells. An association between cathepsin D tissue concentration and aggressiveness of tumors has been detected in different cancer types, as well as in metastatic melanoma. METHODS The concentration of cathepsin D was measured immunoradiometrically (ELSA-CATH-D kit, CIS Bio International) in the cytosols of 51 primary cutaneous melanomas (with Breslow index < 4 mm) to estimate the tissue concentrations of cathepsin D in early cutaneous melanoma. RESULTS A significantly elevated concentration of cathepsin D was measured in the tumor cytosols as compared to adjacent normal tissue (44.2 vs. 14.7 pmol/mg of total protein, P < 0.001). CONCLUSIONS Our results indicate that cathepsin D is expressed at high levels by melanoma cells. The extremely high expression of cathepsin D in two of our patients, with later progression of the disease over a 42-month follow-up period, suggests a possible correlation between the cathepsin D tissue concentration and the prognosis of primary cutaneous malignant melanoma.

Abstract
Our analyses of cathepsin H activity levels and protein forms in human colorectal cancers compared to matched control mucosa support the concept that altered proteinase expression patterns may reflect both cancer stage and site. Cathepsin H-specific activity was significantly increased in colorectal cancers compared to control mucosa (P = 0.003; n = 77). Highest specific activities and cancer/normal ratios (C/N) for activity were measured in Dukes' B and C stage carcinomas, cancers involved in local spread and invasion to lymph nodes. In contrast, cathepsin B and L activities analysed in the same paired extracts had been shown to be most frequently elevated in earlier stage carcinomas (Dukes' A and B), confirming that cathepsin H demonstrates a distinct pattern of expression during colorectal cancer progression. Although cathepsin H activities were most commonly elevated in Dukes' C cancers at all colon sites, both specific activity and C/N ratios were significantly higher for cancers of the left colon compared to other colon locations. A subset of 43 paired extracts analysed on Western blots also revealed consistent changes in cathepsin H protein forms in cancers. Normal mucosa typically showed a strong protein doublet at 31 and 29 kDa while cancers demonstrated decreased expression or total loss of the 31 kDa protein (90% of cases), equal or increased expression of the 29-kDa protein (67% of cases) and the new appearance or up-regulation of a cathepsin H band at 22 kDa (78% of cases). C/N ratios for cathepsin H enzyme activity correlated significantly with C/N ratios for the 29 kDa mature single-chain protein form (P < 0.001), with increased activity most commonly associated with elevated expression of 29-kDa cathepsin H but also with up-regulation of the 22-kDa band, suggesting a shift to more fully processed, mature active cathepsin H protein forms in cancers. Changes in cathepsin H expression were also detected by immunohistochemistry as elevated cathepsin H staining in tumour epithelial cells.

Abstract
The cysteine protease cathepsin B is upregulated in a variety of tumors, particularly at the invasive edges. Cathepsin B can degrade extracellular matrix proteins, such as collagen IV and laminin, and can activate the precursor form of urokinase plasminogen activator (uPA), perhaps thereby initiating an extracellular proteolytic cascade. Recently, we demonstrated that procathepsin B interacts with the annexin II heterotetramer (AIIt) on the surface of tumor cells. AIIt had previously been shown to interact with the serine proteases: plasminogen/plasmin and tissue-type plasminogen activator (tPA). The AIIt binding site for cathepsin B differs from that for either plasminogen/plasmin or tPA. AIIt also interacts with extracellular matrix proteins, e.g., collagen I and tenascin-C, forming a structural link between the tumor cell surface and the extracellular matrix. Interestingly, cathepsin B, plasminogen/plasmin, t-PA and tenascin-C have all been linked to tumor development. We speculate that colocalization through AIIt of proteases and their substrates on the tumor cell surface may facilitate: (1) activation of precursor forms of proteases and initiation of proteolytic cascades; and (2) selective degradation of extracellular matrix proteins. The recruitment of proteases to specific regions on the cell surface, regions where potential substrates are also bound, could well function as a 'proteolytic center' to enhance tumor cell detachment, invasion and motility.

Abstract
In order to evaluate the role of cysteine peptidase cathepsin H (Cath H) in human lung cancer its protein levels were determined in 148 pairs of lung tumour tissue and adjacent non-tumourous lung parenchyma using the enzyme-linked immunosorbent assay technique. Additionally, Cath H levels were determined in sera of 171 patients with malignant tumours, 34 patients with benign lung diseases and 47 healthy controls. The median level of Cath H in tumour tissue was 0.64 times that in the corresponding lung parenchyma. Relating tumour levels with histological type we found higher Cath H levels in small-cell and adenocarcinomas and lower levels in squamous cell carcinoma, large-cell carcinoma and secondary tumours. A significant difference in Cath H level between lung tumour tissue and non-tumourous lung parenchyma was associated with the group of cigarette smokers (156 vs 263 ng mg(-1) protein, P < 0.001). For this group of patients Cath H tumour levels correlated with the survival rate, while for the entire patient population this was not the case. Smokers with high tumour levels of Cath H experienced poor survival. Cath H was significantly higher in sera of patients with malignant and benign lung diseases than in control sera (P < 0.001). The increase was significant for all histological types, being the highest in small-cell and squamous cell carcinomas. Our study reveals that in lung tumours there is different behaviour of Cath H compared with other cysteine peptidases, e.g. cathepsin B and cathepsin L. Variations between tissue and serum levels of Cath H indicate either reduced expression or enhanced secretion of this enzyme in lung tumours.

Abstract
In order to evaluate the possible role of the proteolytic enzyme cathepsin B (cath B) in human non-small cell lung cancer (NSCLC) we examined cath B concentrations (cath B(C)) and activities (cath B(A)) in homogenates of 127 pairs of lung tumour tissues and corresponding non-tumourous lung parenchyma. Total cath B activity (cath B(AT)) and enzymatic activity of the fraction of cath B, which is stable and active at pH 7.5 (cath B(A7.5)) were determined by a fluorogenic assay using synthetic substrate Z-Arg-Arg-AMC. The immunostaining pattern of cath B was determined in 239 lung tumour tissue sections, showing the presence of the enzyme in tumour cells (cath B(T-I)) and in tumour-associated histiocytes (cath B(H-I)). The median levels of cath B(AT), cath B(A7.5) and cath B(C) were 5.6-, 3.2- and 9.1-fold higher (P < 0.001), respectively, in tumour tissue than in non-tumourous lung parenchyma. Out of 131 tissue sections from patients with squamous cell carcinoma (SCC), 59.5% immunostained positively for cath B, while among the 108 adenocarcinoma (AC) patients 48.2% of tumours showed a positive reaction. There was a strong relationship between the levels of cath B(AT), cath B(A7.5), cath B(C) and cath B(T-I) in the primary tumours and the presence of lymph node metastases. Significant correlation with overall survival was observed for cath B(T-I) and cath B(A7.5) (P < 0.01 and P < 0.05, respectively) in patients suffering from SCC. In these patients positive cath B in tumour cells (cath B(T-I)) and negative cath B in histiocytes (cath B(H-I)) indicated significantly shorter survival rate compared with patients with negative cath B(T-I) and positive cath B(H-I) (P < 0.0001). In contrast, in AC patients, both, positive cath B(T-I) and positive cath B(H-I), indicated poor survival probability (P < 0.014). From these results we conclude that the proteolytic enzyme cath B is an independent prognostic factor for overall survival of patients suffering from SCC of the lung.

Abstract
Elevated activities of cysteine proteinases, the cathepsins B, H, L (CB, CH, CL) and diminished cysteine protease inhibitors (CPI) have been demonstrated in a variety of tumours and have been suggested to contribute to invasion and metastasis. The situation for prostate cancer is still unknown. In this study, using fluorimetric assays, the catalytic activities of CB, CH, CL were measured in prostatic tissue samples after radical prostatectomy, adenomectomy, transurethral resection of the prostate, in cell cultures grown from cancerous and non-cancerous parts of human prostate after prostatectomy and in the cell lines LNCaP, DU 145 and PC 3. CPIs were determined using heat activation before testing their inhibitory activity against purified CB. Comparing matched pairs of normal and cancerous tissue samples from the prostate, significantly decreased levels of CB, CL in malignant parts of the prostate were found. In contrast, primary cell cultures from cancerous samples showed elevated levels of CB, CH, CL and increased ratios of cathepsins to CPI compared with cell cultures from normal prostate. Established cell lines showed a similar distribution pattern of each cathepsin, DU 145 containing the highest levels, followed by LNCaP and PC 3. Our results suggest that elevated cathepsin levels and consequently increased ratios of cathepsins to CPI in primary cell cultures from cancerous versus non-cancerous parts of the prostate may be indicative of a cellular proteolytic imbalance in prostatic cancer cells. In this respect, primary cell culture experiments should be preferred to determinations in tissue samples.

Abstract
Aspartic proteinase cathepsin D (CD) is believed to be associated with proteolytic processes leading to local invasion and seeding of tumour cells. To estimate a potential prognostic value of cathepsin D in squamous cell carcinoma of the head and neck, its total concentration was measured immunoradiometrically (ELSA-CATH-D kit, CIS bio international) in cytosols of tumour and adjacent normal tissue samples from 111 patients; in 42/111 patients, the CD concentration was determined in serum samples obtained at diagnosis (serum no. 1) and after the therapy (serum no. 2) from each of these patients. Sera of 15 healthy volunteers served as controls. A significantly elevated concentration of CD was measured in tumour cytosols as compared to normal tissue cytosols (31.1 versus 12.6 pmol/mgp, P < 0.0001) and in cytosols of normal laryngeal tissue than of the oral cavity or pharynx (13.3 versus 11.2 pmol/mgp, P = 0.03). The higher CD tumour concentration correlated with the age of the patients (< or =60 versus >60 years, 28.8 versus 32.8 pmol/mgp, P = 0.045) and histopathological tumour grade (G1+2 versus G3, 32.6 versus 24.4 pmol/mgp, P = 0.02). In serum samples, a lower concentration of CD was measured in the control group than in the patients (3.6 versus 4.1 pmol/mls, P = 0.045) and in serum no. 1 than in serum no. 2 (4.1 versus 5.1 pmol/ mls. P = 0.05). The CD concentration in sera obtained at diagnosis was stage-dependent (S(I-III) versus S(IV), 3.9 versus 4.7 pmol/ mls. P = 0.09); there was a trend towards lower CD concentrations with an increasing time delay in serum no. 2 sampling (Rs = -0.20, P = 0.21). No correlation was observed between cytosolic and serum concentrations of CD. We conclude that our results confirm a specific role of CD in the process of invasion and metastasis of squamous cell carcinoma of the head and neck, which might also be of prognostic value in this particular cancer type.

Abstract
The aim of this study was to determine urokinase-type plasminogen activator (uPA) and plasminogen activator inhibitor type 1 (PAI-1) concentrations in tumour and adjacent normal tissue samples from 58 patients, and in serum samples from 40 of 58 patients with squamous cell carcinoma of the head and neck obtained at diagnosis and after completion of therapy. uPA and PAI-1 serum concentrations were also measured in 28 healthy volunteers who served as controls. Measurements were made using enzyme-linked immunosorbent assay (ELISA) techniques. For both uPA and PAI-1, significantly elevated concentrations were measured in tumour tissue as compared with normal tissue (uPA: 8.89 versus 0.41 ng/mg total protein (mgp), P < 0.0001; PAI-1: 23.9 versus 1.47 ng/mgp, P < 0.0001). A statistically significant difference in uPA concentrations was found between normal laryngeal and nonlaryngeal tissue (0.52 versus 0.3 ng/mgp, P = 0.008), and in PAI-1 concentrations between T1 + 2 and T3 + 4 stage of disease (17.32 versus 35.63 ng/mgp, P = 0.04). The uPA concentrations positively correlated with those of PAI-1 measured in both tumour (Rs = 0.62, P < 0.0001) and normal tissue (Rs = 0.30, P = 0.02). In serum samples, lower concentrations of PAI-1 were measured in the control group than in patients with cancer (412.0 versus 680.5 ng/ml serum (mls), P = 0.0006). The time of collection of the serum sample did not influence uPA and PAI-1 concentrations, and no association was observed between their concentrations and any clinical and histopathological prognostic factors tested. Our results indicate that both uPA and PAI-1 may play a specific role in the process of invasion and metastasis, and might also be of prognostic value in squamous cell carcinoma of the head and neck.

Abstract
In human lung tumor tissue specimen (n = 73) concentrations of stefins A and B were found to be increased 2.0-fold (p < 0.01) and 1.3-fold (p < 0.01), respectively, as compared to matched normal tissue. Stefin A and B concentrations were higher in primary tumors than in secondary tumors, i.e. metastases from other organs to the lung (p < 0.01; p < 0.05, respectively). Cystatin C concentrations were rather low and did not differ between tumor and normal tissue. Both concentrations of stefins did not correlate with TNM stages. Stefin A was higher in squamous cell carcinoma than in adenocarcinoma (p < 0.01), while stefin B did not show such a difference. At investigation of a relationship between survival probability of patients with primary tumors it was found that increased stefin B concentrations and total cysteine-protease-inhibitory activities but not stefin A concentrations were positively correlated with survival probability. It is concluded that stefins A and B are major contributors to the cysteine protease inhibitory activity in primary lung tumors. Stefin B proved to be a prognostic factor, especially in squamous cell carcinoma.
