Abstract
The human lung carcinoma cell line DLKP was exposed to sequential pulses of 10 commonly used chemotherapeutic drugs (VP-16, vincristine, taxotere, mitoxantrone, 5-fluorouracil, methotrexate, CCNU, BCNU, cisplatin and chlorambucil); resulting cell lines exhibited resistance to the selecting agents (ranging approx. 1.5- to 36-fold) and, in some cases, cross-resistance to methotrexate (approx. 1.4- to 22-fold), vincristine (1.6- to 262-fold), doxorubicin (Adriamycin, approx. 1.1- to 33-fold) and taxotere (approx. 1.1- to 36-fold). Several of the variants displayed collateral sensitivity to cisplatin. A marked increase in in vitro invasiveness and motility was observed with variants pulsed with mitoxantrone, 5-fluorouracil, methotrexate, BCNU, cisplatin and chlorambucil. There was no significant change in invasiveness of cells pulsed with VP-16, vincristine, taxotere or CCNU. All of the pulse-selected variants showed elevated levels of MDR-1/P-gp protein by Western blot analysis, although mdr-1 mRNA levels were not increased (except for DLKP-taxotere). In DLKP-taxotere, MRP1 protein levels were also greatly elevated, but mrp1 mRNA levels remained unchanged. BCRP was upregulated in DLKP-mitoxantrone at both the mRNA and protein levels. Gelatin zymography, Western blot and RT-PCR showed that DLKP and its variants secreted MMPs 2, 9 and 13. MMP inhibition assays suggested that MMP-2 plays a more important role than MMPs 9 and 13 in cell invasion of these DLKP drug-resistant variants in vitro. These results indicate that drug exposure may induce not only resistance but also invasiveness in cancer cells.

Abstract
OBJECTIVE To study the association between silica exposure and rheumatoid arthritis and how it is modified by cigarette smoking. METHODS Data were analysed from 276 male cases and 276 male controls aged 18 to 70 years, included in a Swedish population based study between May 1996 and June 2001. A case was defined as a person recently diagnosed with rheumatoid arthritis according to the ACR criteria. Controls were selected from the study base as a stratified random sample accounting for age, sex, and residency. Men with a self reported history of work with rock drilling, stone crushing, or exposure to stone dust in general were defined as silica exposed. Rheumatoid factor (RF) status among cases was recorded. RESULTS Silica exposed men had increased risk of rheumatoid arthritis, with an odds ratio (OR), adjusted for age, residential area, and smoking, of 2.2 (95% confidence interval, 1.2 to 3.9) among men aged 18 to 70 years, and 2.7 (1.2 to 5.8) among those aged 50 to 70 years. Men who had worked with rock drilling or stone crushing (regarded as highly exposed) had a slightly greater increase in risk of rheumatoid arthritis than silica exposed men in general, with an OR of 3.0 (1.2 to 7.6). The joint effects of silica exposure and smoking were compatible with synergy between these two exposures in the development of rheumatoid arthritis but this was not conclusive. CONCLUSIONS Silica exposure is associated with increased risk of developing rheumatoid arthritis. This association is not explained by smoking habits.

Abstract
Mannheimia haemolytica infection of the lower respiratory tract of cattle results in a bronchofibrinous pneumonia characterized by massive cellular influx and lung tissue remodeling and scarring. Since altered levels of gelatinases and their inhibitors have been detected in a variety of inflammatory conditions and are associated with tissue remodeling, we examined the presence of gelatinases in lesional and nonlesional lung tissue obtained from calves experimentally infected with M. haemolytica. Lesional tissue had elevated levels of progelatinase A and B and active gelatinase A and B when compared with nonlesional tissue obtained from the same lung lobe. In vitro, M. haemolytica products stimulated production of gelatinase B, but not its activation, by bovine monocytes. Alveolar macrophages showed constitutive production of gelatinase B but no change in response to M. haemolytica products. Bovine neutrophils exposed to M. haemolytica products also released gelatinase B, and there was a significant increase in the activated form of this enzyme. These effects were virtually identical when recombinant O-sialoglycoprotease was used to stimulate these cells. M. haemolytica products also enhanced the expression by bovine monocytes and alveolar macrophages of the tissue inhibitor of metalloproteinase 1. Our results provide evidence that matrix metalloproteinases are activated in lung lesions from cattle with shipping fever and that M. haemolytica virulence products induce production, release, and especially activation of gelatinase B by bovine inflammatory cells in vitro.

Abstract
Intratracheal instillation studies have shown that exposure to silicon carbide whiskers (SiCW), an asbestos substitute, produces pulmonary fibrotic changes, suggesting that SiCW might have fibrogenic potential. It has been theorized that Clara cell secretory protein (CCSP) plays a critical role in regulating the acute inflammatory response in the lung. The present study was conducted to investigate the time course of the expression of CCSP in lungs exposed to SiCW in vivo. Male Wistar rats were administered 2 mg or 10 mg of SiCW suspended in saline by a single intratracheal instillation and were sacrificed at 3 days, 1 week, 1 month, 3 months and 6 months of recovery time. The expression of CCSP was observed by reverse transcriptase-polymerase chain reaction (RT-PCR), Western blot and immunostaining. Exposure to 10 mg of SiCW decreased in levels of CCSP mRNA at 3 days, 1 week, 1 month and 6 months following intratracheal instillation. The protein level of CCSP in SiCW-exposed rats was decreased at 1 day, 3 days and 1 month after a single instillation of 2 and 10 mg. These findings suggest that CCSP are involved not only in the acute injury but also in the chronic injury of the lung exposed to SiCW.

Abstract
In this study, we examined the sequential expression of several matrix metalloproteinases (MMPs), tissue inhibitors of metalloproteinases (TIMPs), and growth factors as well as the presence of apoptosis in a model of pulmonary fibrosis induced in rats with paraquat and hyperoxia. Animals showing neither clinical nor morphological changes with this double aggression were classified as "resistant". Rats were killed at 1, 2, 3, and 6 wk, and lungs were used for collagen content, gene expression by real-time PCR, gelatinolytic activity by zymography, apoptosis by in situ DNA fragmentation, and protein localization by immunohistochemistry. Our results showed a significant decrease of collagenases MMP-8 and MMP-13, with an increase of TIMP-1 and transforming growth factor-beta. Immunoreactive TIMP-1 was increased in experimental rats and primarily localized in alveolar macrophages. Expression of gelatinases MMP-2 and MMP-9 mRNAs was not affected, but lung zymography revealed an increase in progelatinase B, progelatinase A, and its active form. Epithelial apoptosis was evident from the first week, whereas at later periods, interstitial cell apoptosis was also noticed. Resistant animals behave as controls. These findings suggest that an imbalance between collagenases and TIMPs, excessive gelatinolytic activity, and epithelial apoptosis participate in the fibrotic response in this experimental model.

Abstract
Connective tissue growth factor (CTGF) is felt to be one of the key profibrotic factors and is a downstream effector molecule mediating the action of transforming growth factor (TGF)-beta1, a cytokine known to induce severe and progressive fibrosis. However, the in vivo fibrogenic effect of isolated CTGF expression is not well described. We used adenoviral gene transfer to transiently overexpress CTGF in rat lungs after intratracheal administration and compared it with transient overexpression of active TGF-beta1 delivered by a similar adenovirus vector. This high expression of CTGF over 6-10 days induced a moderate but reversible fibrosis. We observed an increase of fibronectin, procollagen 1a2, and endogenous CTGF gene expression at 14 days, which suggested an indirect activation by CTGF. Tissue inhibitor of metalloproteinase-1 was weakly and transiently upregulated after CTGF exposure. These same genes were robustly and persistently stimulated by TGF-beta1 from Day 3 to Day 21. This data suggested that CTGF may act as a TGF-beta1 cofactor rather than a direct fibrogenic factor. We demonstrate that CTGF overexpression can initiate fibrogenic activity but likely requires the presence of additional factors, such as tissue inhibitor of metalloproteinase-1, to maintain a nonfibrolytic environment and to cause progression of fibrosis.

Abstract
STUDY OBJECTIVE To evaluate the effect of CP-471,474 (Pfizer Global Research and Development; Groton, CT), a broad-spectrum inhibitor of matrix metalloproteinases (MMPs) in an experimental model of emphysema. DESIGN Randomized, double-blinded, controlled experiment. SETTING Biochemistry and morphology laboratories and animal research facility. METHODS Guinea pigs were exposed to cigarette smoke over 1 month, 2 months, and 4 months, and half of the animals received CP-471,474. Age-matched guinea pigs exposed to room air were used as control animals. After death, the lungs were lavaged with saline solution, and MMPs in the lavage fluid were determined by zymography and immunoblot. Lungs were fixed for histology, immunohistochemistry, and morphometry. RESULTS Following a 1-month exposure to tobacco smoke, semiquantitative histologic assessment showed moderate lung inflammation, which progressed in extent and severity and reached a peak at 2 months. CP-471,474 significantly reduced both the extent (p < 0.002) and severity (p < 0.05) of inflammation at 2 months. At 4 months, a spontaneous reduction of the inflammatory response was observed in both treated and untreated animals, and consequently no difference was observed between both. Emphysematous changes, revealed by a significant increase in the average size of alveoli, were detected at 2 months and 4 months of tobacco smoke exposure. The inhibitor significantly decreased the destructive lesions mainly at 2 months (p < 0.0001) and also at 4 months (p < 0.02). Smoking increased MMP-9 and MMP-1 activities as shown by zymography and immunoblot. Immunoreactive MMP-9 was mainly localized in alveolar and bronchiolar epithelial cells, macrophages, and airways smooth-muscle cells. CONCLUSION These findings support a role for MMPs in the early inflammatory response and in the emphysematous lesions provoked by cigarette smoking.

Abstract
The number of metastatic foci in silicotic mice is approximately 1.5-fold that in normal mice and in mice treated with TiO2 as inert particles. Expression of matrix metalloproteinases (MMPs) tissue inhibitors of metalloproteinases (TIMPs) and selectins was investigated in silicotic mice with lung tumor metastasis. Expression of MMP-9 and P-selectin mRNA, but not MMP-2 and E-selectin, increased significantly, showing decreases of the ratio of expression in TIMPs/MMP-9 in tumor-bearing silicotic mice compared with the tumor-bearing normal mice and mice treated with TiO2. Pretreatment with anti-P-selectin antibody inhibited number of metastatic foci significantly in silicotic mice, while pretreatment of animals with anti MMP-9 antibody showed slight decrease of metastatic foci. This evidence indicated that up-regulation of P-selectin expression contributed to enhanced rate of tumor metastasis in lung with silicosis.

Abstract
BACKGROUND MMP-13 (collagenase-3) is a metalloproteinase with potent degradative activity against a variety of elements of the extracellular matrix. Its expression has been described in some human carcinomas, where it seems to play a role in tumor progression and metastasis. The objective of this study was to investigate the expression and clinical significance of MMP-13 in gastric carcinomas. PATIENTS AND METHOD MMP-13 expression was analyzed by immunohistochemistry in resected specimens from 44 patients with gastric adenocarcinoma. The mean ( standard error) follow-up period was 21.4 3.2 months. RESULTS A total of 14 gastric carcinomas (31.8%) showed positive immunostaining for MMP-13. The percentage of MMP-13-positive tumors was significantly (p = 0.009) higher in stage IV carcinomas (69.2%) than in lower stages (I: 22.2%; II: 12.5%; and III: 14.3%), as well as in nonresectable tumors (R1 and R2) (61.5%) than in resectable carcinomas (R0) (19.4%) (p = 0.017). Likewise, MMP-13 tumor expression was significantly associated with shortened overall survival in both the entire group of patients (p = 0.0006) and in the subgroup of patients with resectable tumors (p = 0.018). CONCLUSIONS Our results suggest that, in patients harboring gastric adenocarcinoma, MMP-13 tumor expression is associated with higher tumor aggressiveness and a poor prognosis.

Abstract
Matrix metalloproteinase (MMP)-9 (Gelatinase B, 92-kD type IV collagenase, EC 3.4.24.35) is an MMP that is present in low quantities in the healthy adult lung, but much more abundant in several lung diseases, including asthma, idiopathic pulmonary fibrosis (IPF), and chronic obstructive pulmonary disease (COPD). Despite numerous reports of MMP-9 in these and other lung diseases, whether MMP-9 is causal in lung remodeling or part of the inflammatory and reparative response remains to be determined. Many intrinsic lung cells can be stimulated to produce MMP-9, but much of the information regarding MMP-9 in the lung deals with MMP-9 from inflammatory cells. The multiple locations and cell types producing MMP-9 are consistent with multiple functions in different microenvironments. In addition to digestion of structural proteins and antiproteases, MMP-9 can modify cellular function by regulation of cytokines and matrix-bound growth factors. Determining the role of MMP-9 in health and disease will be important, because broad spectrum and specific inhibitors will soon be available to enable conversion of the bench knowledge to bedside practice. This review addresses the current understanding of MMP-9 in human asthma, IPF, and COPD, and in animal models of these conditions.

Abstract
Matrix metalloproteinases (MMPs) capable of degrading various components of connective tissue matrices, and tissue inhibitor metalloproteinases (TIMPs) are considered important in lung parenchymal remodeling and repair processes in pulmonary diseases. Induced sputum (IS) is a reliable noninvasive method to investigate pathogenesis, pathophysiology and treatment of lung disease. This study was designed to determine whether IS-MMP9/TIMP1 levels demonstrate lung parenchymal remodeling in sarcoidosis (SA) and Crohn's disease (CRD) patients. Sputum was induced and processed conventionally in 13 SA patients, 18 CRD patients and 9 controls. Two-hundred cells were counted on Giemsa-stained cytopreps, and T lymphocytes subsets (CD4 = T helper and CD8 = T suppressor cytotoxic cells) were analysed by FACS using monoclonal antibodies.MMP-9 and TIMP-1 were measured using commercial ELISA kits. MMP-9 concentrations, but not those of TIMP-1, were significantly greater in the sputum supernatant in SA and CRD patients compared to controls (P = 0.018 and P = 0.0019, respectively). The molar ratio, MMP-9/TIMP-1, was significantly higher in SA and CRD patients compared to controls (P = 0.008 and P = 0.024, respectively). Gelatinase species having a molecular weight similar to that of MMP-9 were demonstrated by zymographic analysis. MMP-9 levels were highly correlated with the CD4/CD8 ratio and DLCO capacity in SA but less in CRD patients. MMP-9 levels in IS provide a sensitive marker for pulmonary damage.

Abstract
Pulmonary fibrosis is characterized by excessive deposition of extracellular matrix in the interstitium, resulting in impaired lung function and respiratory failure. Investigation of the differences in individual susceptibility to the development of fibrosis may help to detect patients that are at risk to fibrosis when exposed to fibrogenic stimuli. In this study we used adenoviral gene transfer to transiently expose a fibrosis-prone (C57BL/6) and a fibrosis-resistant (Balb/c) mouse strain to high levels of active transforming growth factor (TGF)-beta1, a key profibrotic cytokine. Balb/c mice developed significantly less fibrosis compared with C57BL/6 mice in response to active TGF-beta1 despite higher levels of the transgene protein in the lung. This was not due to a general unresponsiveness of cells to TGF-beta1, because primary fibroblasts of both strains increased collagen synthesis upon stimulation with TGF-beta1 in vitro to the same degree. However, TGF-beta1 induced a strong upregulation of tissue inhibitor of metalloprotease-1 gene in pulmonary fibroblasts as well as in lungs of C57BL/6 mice, in contrast to a weak induction in Balb/c mice. These findings suggest that the differences in susceptibility to pulmonary fibrosis are downstream from TGF-beta1 and that fibrosis-prone individuals may have an altered collagen metabolism in the lungs that is balanced toward a "nondegrading" environment.

Abstract
IL-13 potently stimulates eosinophilic and lymphocytic inflammation and alveolar remodeling in the lung, effects that depend on the induction of various matrix metalloproteinases (MMPs). Here, we compared the remodeling and inflammatory effects of an IL-13 transgene in lungs of wild-type, MMP-9-deficient, or MMP-12-deficient mice. IL-13-induced alveolar enlargement, lung enlargement, compliance alterations, and respiratory failure and death were markedly decreased in the absence of MMP-9 or MMP-12. Moreover, IL-13 potently induced MMPs-2, -12, -13, and -14 in the absence of MMP-9, while induction of MMPs-2, -9, -13, and -14 by IL-13 was diminished in the absence of MMP-12. A deficiency in MMP-9 did not alter eosinophil, macrophage, or lymphocyte recovery, but increased the recovery of total leukocytes and neutrophils in bronchoalveolar lavage (BAL) fluids from IL-13 transgenic mice. In contrast, a deficiency in MMP-12 decreased the recovery of leukocytes, eosinophils, and macrophages, but not lymphocytes or neutrophils. These studies demonstrate that IL-13 acts via MMPs-9 and -12 to induce alveolar remodeling, respiratory failure, and death and that IL-13 induction of MMPs-2, -9, -13, and -14 is mediated at least partially by an MMP-12-dependent pathway. The also demonstrate that MMPs-9 and -12 play different roles in the generation of IL-13-induced inflammation, with MMP-9 inhibiting neutrophil accumulation and MMP-12 contributing to the accumulation of eosinophils and macrophages.

Abstract
We characterized clinical and clinicopathological features, and the involvement of gelatinolytic matrix metalloproteinases (MMP-2 and -9) in canine pulmonary eosinophilia (PE). Study material consisted of 20 PE dogs and 16 healthy beagles. All dogs underwent a similar clinical examination and bronchoalveolar lavage (BAL). Analysis for cell count and differential cell count of BAL fluid (BALF), arterial blood gas analysis before and after BAL, and thoracic radiographs before BAL and after treatment were obtained. Twelve dogs were re-evaluated and six relavaged. MMP-2 and MMP-9 in BALF were analysed by zymography, Western immunoblotting and immunocytochemistry. In the PE dogs, BALF, cell count, number and percentage of eosinophils, and numbers of macrophages, lymphocytes, neutrophils, mast cells and epithelial cells were all significantly elevated. Blood eosinophilia was detected in half of the PE dogs. Three PE dogs had mild hypoxaemia. The BAL procedure had an equal effect on PE and healthy dogs' arterial blood gas values. Bronchointerstitial densities were seen in PE dogs' radiographs. Treatment of PE decreased BALF cell count, eosinophil count and percentage and diminished radiographic changes. Gelatinolytic activity was higher in PE dogs' BALF. BALF macrophages and epithelial cells were the principal sources of the MMP-9.

Abstract
BACKGROUND & AIMS In pancreatitis-associated lung injury, neutrophils (PMN) access the lung by migration through endothelial basement membranes. We hypothesize that degeneration of the basement membrane by specific PMN-produced matrix metalloproteinases (MMPs) may facilitate this process. METHODS Mild or severe pancreatitis was induced in rats and the consequent pulmonary injury characterized. MMP-2 and MMP-9 activity in supernatant of PMN cultures and homogenates of lungs were assessed by zymography and Western blot. Congruence of PMN and MMP expression in lung tissue was evaluated by neutrophil depletion and fluorescent immunohistochemistry (IHC). The contribution of MMPs to PMN transmigration and lung injury was tested with the MMP inhibitor batimastat (BB-94) in vitro (PMN transmigration across matrigel chambers) and in vivo (myeloperoxidase activity and Evans blue in broncho-alveolar lavage fluid). RESULTS MMP-9 was highly expressed in lungs and supernatant of neutrophil cultures in severe pancreatitis, and, to a lesser degree, in mild pancreatitis. Lung IHC showed colocalization of MMP-9 and PMN. PMN depletion simultaneously reduced neutrophil infiltration and MMP-9 levels in lung tissue. Trypsin, interleukin 1 beta, and tumor necrosis factor (TNF)-alpha all potently stimulated MMP-9 release from PMN. BB-94 significantly reduced TNF-alpha-induced PMN transmigration across matrigel and ameliorated transendothelial PMN migration and protein leak in severe pancreatitis. CONCLUSIONS MMP-9 secretion by PMN can be stimulated by trypsin and proinflammatory cytokines and increases in pancreatitis in proportion to its severity. MMP inhibition reduces PMN transmigration and reduces resultant alveolar-capillary leakage. These findings suggest an important role for MMP-9 from PMN in the pathogenesis of pancreatitis-associated lung injury.

Abstract
We investigated the kinetics of matrix metalloproteinases (MMPs) and their regulatory factors mRNAs in the kidneys of mercuric chloride-treated Brown Norway rats. The expression of MMP-1 mRNA remained at lower levels than control, while other MMPs mRNAs were upregulated. The expression of tissue inhibitor of matrix metalloproteinase (TIMP)-1 mRNA showed significant upregulation. On the other hand, the expressions of TIMP-2 and TIMP-3 mRNAs were not significantly changed. In the plasmin-dependent pathway, the expression of plasminogen activator inhibitor (PAI-1) mRNA was continuously increased, while the expression of urokinase-type plasminogen activator (uPA) mRNA was not increased. The signals of TIMP-1 and PAI-1 mRNAs examined by in situ hybridization, were localized in the regenerative epithelial cells of the proximal tubules. In conclusion, these findings suggest that the activity of MMPs may bealtered by MMP-1 downregulation and inhibition of MMP activity by PAl-1 and TIMP-1 generated from tubular epithelial cells.

Abstract
Murine exposure to silica is associated with enhanced tumor necrosis factor alpha (TNF-alpha) expression and matrix deposition. The regulation of TNF is mediated through TNF receptor (TNFR) activation of transcription factors. In the present work we have studied the importance of the individual TNFR in silica-induced lung inflammation and matrix deposition in mice. We studied RNA expression of TNF, alpha1(I) collagen, interstitial collagenase (MMP-13), and its inhibitor (TIMP-1) in the lungs of silica-treated mice. Furthermore, we correlated MMP-13/TIMP-1 RNA abundance with activation of the transcription factors AP-1 and NF-kappaB in the lungs of C57BL/6 mice, and of mice deficient in one of the two types of TNFR (p55(-/-) or p75(-/-)), exposed to silica (0.2 g/kg) or saline by intratracheal instillation. Animals were killed 28 d after exposure and lung hydroxyproline (HP), TNF, alpha1(I) collagen, MMP-13, and TIMP-1 RNA abundance was measured. AP-1 and NF-kappaB activation was studied by gel-shift assays. Compared with C57BL/6 mice, p55(-/-) and p75(-/-) mice significantly (*p < 0.05) decreased lung HP accumulation in response to silica. All murine strains enhanced TNF and alpha1(I) collagen mRNA in response to silica. Enhanced (p < 0.05) MMP-13 RNA expression was also observed in all murine strains in response to silica. Enhanced (p < 0.05) TIMP-1 RNA expression was observed in C57BL/6 mice, but not in p55(-/-) or p75(-/-) mice, in response to silica. NF-kappaB activation was observed in all murine strains, whereas AP-1 activation was observed only in C57BL/6 mice after silica treatment. These data suggest that TNFR deletion modifies MMP-13/ TIMP-1 expression in favor of matrix degradation.

Abstract
Fibroblast proliferation and extracellular matrix accumulation characterize idiopathic pulmonary fibrosis (IPF). We evaluated the presence of tissue inhibitor of metalloproteinase (TIMP)-1, -2, -3, and -4; collagenase-1, -2, and -3; gelatinases A and B; and membrane type 1 matrix metalloproteinase (MMP) in 12 IPF and 6 control lungs. TIMP-1 was found in interstitial macrophages and TIMP-2 in fibroblast foci. TIMP-3 revealed an intense staining mainly decorating the elastic lamina in vessels. TIMP-4 was expressed in IPF lungs by epithelial and plasma cells. TIMP-2 colocalized with Ki67 in fibroblasts, whereas TIMP-3 colocalized with p27 in inflammatory and epithelial cells. Collagenase-1 was localized in macrophages and alveolar epithelial cells, collagenase-2 was localized in a few neutrophils, and collagenase-3 was not detected. MMP-9 was found in neutrophils and subepithelial myofibroblasts. Myofibroblast expression of MMP-9 was corroborated in vitro by RT-PCR. MMP-2 was noticed in myofibroblasts, some of them close to areas of basement membrane disruption, and membrane type 1 MMP was noticed in interstitial macrophages. These findings suggest that in IPF there is higher expression of TIMPs compared with collagenases, supporting the hypothesis that a nondegrading fibrillar collagen microenvironment is prevailing.
