Abstract
Milk thistle (Silybum marianum) is well-known for its antioxidant activity due to the presence of silymarin. Albeit some studies show a potential for skin inflammation, its activity against dermal MMP-9 and MMP-2 remains to be studied. Silymarin isolated from an S. marianum herbal extract was tested for gelatinase inhibition in the presence of isolated MMP-9 and in dermal adenocarcinome HaCaT cells. Silymarin was then further tested in vivo, using a cutaneous inflammation mice model mediated by reactive oxygen species. Silymarin was able to significantly inhibit gelatinolytic activity in vitro without impairing cell growth and viability. Furthermore, inhibition was more pronounced in cells than with the isolated gelatinase, suggesting an additional effect upon metabolic pathways. In vivo, silymarin was able to reduce ear edema up to 74% and attenuated histological lesions. Results highlight silymarin potential for application in skin inflammatory disorders via gelatinase inhibition.

A Potential Prognostic Gene Signature Associated with p53-Dependent NTRK1 Activation and Increased Survival of Neuroblastoma Patients. Cancers (Basel) 2024; 16:722. [PMID: 38398114 PMCID: PMC10886603 DOI: 10.3390/cancers16040722] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2023] [Revised: 02/02/2024] [Accepted: 02/05/2024] [Indexed: 02/25/2024] Open
Abstract
Neuroblastoma is the most common extracranial solid tumour in children, comprising close to 10% of childhood cancer-related deaths. We have demonstrated that activation of NTRK1 by TP53 repression of PTPN6 expression is significantly associated with favourable survival in neuroblastoma. The molecular mechanisms by which this activation elicits cell molecular changes need to be determined. This is critical to identify dependable biomarkers for the early detection and prognosis of tumours, and for the development of personalised treatment. In this investigation we have identified and validated a gene signature for the prognosis of neuroblastoma using genes differentially expressed upon activation of the NTRK1-PTPN6-TP53 module. A random survival forest model was used to construct a gene signature, which was then assessed across validation datasets using Kaplan-Meier analysis and ROC curves. The analysis demonstrated that high BASP1, CD9, DLG2, FNBP1, FRMD3, IL11RA, ISGF10, IQCE, KCNQ3, and TOX2, and low BSG/CD147, CCDC125, GABRB3, GNB2L1/RACK1 HAPLN4, HEBP2, and HSD17B12 expression was significantly associated with favourable patient event-free survival (EFS). The gene signature was associated with favourable tumour histology and NTRK1-PTPN6-TP53 module activation. Importantly, all genes were significantly associated with favourable EFS in an independent manner. Six of the signature genes, BSG/CD147, GNB2L1/RACK1, TXNDC5, FNPB1, B3GAT1, and IGSF10, play a role in cell differentiation. Our findings strongly suggest that the identified gene signature is a potential prognostic biomarker and therapeutic target for neuroblastoma patients and that it is associated with neuroblastoma cell differentiation through the activation of the NTRK1-PTPN6-TP53 module.

Abstract
Elastic fibers do not naturally regenerate in many proteolytic disorders, such as in abdominal aortic aneurysms, and prevent restoration of tissue homeostasis. We have shown drug-based attenuation of the stress-activated protein kinase, JNK-2 to stimulate elastic matrix neoassembly and to attenuate cellular proteolytic activity. We now investigate if JNK2 gene knockdown with small interfering RNA (siRNA) provides greater specificity of action and improved regenerative/antiproteolytic outcomes in a proteolytic injury culture model of rat aneurysmal smooth muscle cells (EaRASMCs). A siRNA dose of 12.5 nM delivered with a transfection reagent significantly enhanced downstream elastic fiber assembly and maturation versus untreated EaRASMC cultures. The optimal siRNA dose was also delivered as a complex with a polymeric transfection vector, polyethyleneimine (PEI) in preparation for future in vivo delivery. Linear 25 kDa PEI-siRNA (5:1 molar ratio of amine to phosphate) and linear 40 kDa PEI-siRNA (2.5:1 ratio) were effective in downregulating the JNK2 gene, and significantly increasing expression of elastic fiber assembly proteins, and decreases in elastolytic matrix metalloprotease-2 versus treatment controls to significantly increase mature elastic fiber assembly. The current work has identified siRNA dosing and siRNA-PEI complexing conditions that are safe and efficient in stimulating processes contributing to improved elastic matrix neoassembly via JNK2 gene knockdown. The results represent a mechanistic basis of a broader therapeutic approach to reverse elastic matrix pathophysiology in tissue disorders involving aberrations of elastic matrix homeostasis, such as in aortic aneurysms. Impact statement The elastic matrix and elastic fibers are key components of the structural extracellular matrix of elastic tissues and are essential to their stretch and recoil and to maintain healthy cell phenotype. Regeneration and repair of elastic matrix is naturally poor and impaired and is an unresolved challenge in tissue engineering. In this work, we investigate a novel gene silencing approach based on inhibiting the JNK2 gene, which provides significant downstream benefits to elastic fiber assembly and maturation. Combined with novel delivery strategies such as nanoparticles, we expect our approach to effect in situ elastic matrix repair in the future.

Abstract
A phenyl ethanoid, salidroside (SAL), and two secoiridoids, 8(E)-nuezhenide (NZD) and ligustroside (LIG), were isolated from fruits of Ligustrumjaponicum, used as traditional folk medicine, and their chemical structures were elucidated by the comparison of spectral data with published literature. Matrix metalloproteinases (MMPs) are major enzymes that play crucial roles in the metastasis and invasive behavior of tumors. In particular, MMP-2 and MMP-9, regulated by the MAPK signaling pathways, including p38, ERK and JNK, are known to play a key role in the degradation of the basement membrane. In the present study, the effects of SAL, NZD and LIG on the expression of MMP-2 and -9 were examined in phorbol 12-myristate 13-acetate (PMA)-induced HT 1080 cells. All the compounds significantly lowered the amount of MMP-2 and MMP-9 released, as determined by gelatin zymography and ELISA. In addition, the mRNA and protein expression levels of MMP-2 and MMP-9 were significantly suppressed, as measured by RT-PCR and Western blotting. According to the Western blotting assay, SAL and LIG effectively reduced the expression of MMP-2 in a dose-dependent manner. NZD lowered the expression of MMP-9 in a similar way. The phosphorylation of p38, ERK and JNK was also significantly suppressed by these compounds. These findings suggest that all the compounds regulate the release and expression of MMP-2 and MMP-9 via MAPK signaling pathways.

Abstract
Ovarian cancer is a heterogeneous disease and is also the major cause of death among women from gynecologic malignancies. A combination of surgery and chemotherapy is the major therapy for ovarian cancer. Unfortunately, despite good response rates to initial surgery and chemotherapy, most patients relapse and have a generally poor survival rate. The present research sheds light on the therapeutic effects of multiple natural products in patients with ovarian cancer. Notably, these natural ingredients do not have adverse effects on healthy cells and tissues, indicating that natural products can serve as a safe alternative therapy for ovarian cancer. Trans-3,4,5′-Trihydroxystibene (resveratrol) is a natural product that is commonly found in the human diet and that has been shown to have anticancer effects on various human cancer cells. This review summarizes current knowledge regarding the progress of resveratrol against tumor cell proliferation, metastasis, apoptosis induction, autophagy, sensitization, and antioxidation as well as anti-inflammation. It also provides information regarding the role of resveratrol analogues in ovarian cancer. A better understanding of the role of resveratrol in ovarian cancer may provide a new array for the prevention and therapy of ovarian cancer.

Abstract
A series of azastilbene derivatives, characterized by the presence of the 1,2,4-oxadiazole-5-one system as a linker of the two aromatic rings of stilbenes, have been prepared as novel potential inhibitors of p38 MAPK. Biological assays indicated that some of the synthesized compounds are endowed with good inhibitory activity towards the kinase. Molecular modeling data support the biological results showing that the designed compounds possess a reasonable binding mode in the ATP binding pocket of p38α kinase with a good binding affinity.

Abstract
Conventional mitogen-activated protein kinase (MAPK) family members regulate diverse cellular processes involved in tumor initiation and progression, yet the role of ERK5 in cancer biology is not fully understood. Triple-negative breast cancer (TNBC) presents a clinical challenge due to the aggressive nature of the disease and a lack of targeted therapies. ERK5 signaling contributes to drug resistance and metastatic progression through distinct mechanisms, including activation of epithelial-to-mesenchymal transition (EMT). More recently a role for ERK5 in regulation of the extracellular matrix (ECM) has been proposed, and here we investigated the necessity of ERK5 in TNBC tumor formation. Depletion of ERK5 expression using the CRISPR/Cas9 system in MDA-MB-231 and Hs-578T cells resulted in loss of mesenchymal features, as observed through gene expression profile and cell morphology, and suppressed TNBC cell migration. In vivo xenograft experiments revealed ERK5 knockout disrupted tumor growth kinetics, which was restored using high concentration Matrigel™ and ERK5-ko reduced expression of the angiogenesis marker CD31. These findings implicated a role for ERK5 in the extracellular matrix (ECM) and matrix integrity. RNA-sequencing analyses demonstrated downregulation of matrix-associated genes, integrins, and pro-angiogenic factors in ERK5-ko cells. Tissue decellularization combined with cryo-SEM and interrogation of biomechanical properties revealed that ERK5-ko resulted in loss of key ECM fiber alignment and mechanosensing capabilities in breast cancer xenografts compared to parental wild-type cells. In this study, we identified a novel role for ERK5 in tumor growth kinetics through modulation of the ECM and angiogenesis axis in breast cancer.

Abstract
Emerging evidence has shown activation of the complement component C5 to C5a in cancer tissues and C5aR expression in breast cancer cells relates to the tumor development and poor prognosis, suggesting the involvement of complement C5a/C5aR pathway in the breast cancer pathogenesis. In this study, we found that as compared to the non-tumoral tissues, both C5aR and MAPK/p38 showed an elevated expression, but p21/p-p21 showed lower expression, in the tumoral tissues of breast cancer patients. Mice deficient in C5aR or mice treated with the C5aR antagonist exhibited attenuation of breast cancer growth and reduction in the p38/p-p38 expression, but increase in p21/p-p21 expression, in the tumor tissues. Pre-treatment of the breast cancer cells with recombinant C5a resulted in reduced p21 expression, and MAPK/p38 inhibitors prevented C5a-induced reduction in p21 expression, suggesting the involvement of the MAPK/p38 signaling pathway in the C5a/C5aR-mediated suppression of p21/p-p21 expression. These results provide evidence that breast cancer development may rely on C5a/C5aR interaction, for which MAPK/p38 pathway participate in down-regulating the p21 expression. Inhibition of C5a/C5aR pathway is expected to be helpful for the treatment of patients with breast cancer.

Abstract
Background Gastric cancer (GC) is one of the most common cancers in the world with a high ratio of mortality. Regarding the late diagnosis, there is a high ratio of distant metastasis among GC cases. Despite the recent progresses in therapeutic modalities, there is not still an efficient therapeutic method to increase survival rate of metastatic GC cases. Main body Apart from the various intracellular signaling pathways which are involved in tumor cell migration and metastasis, the local microenvironment is also a critical regulator of tumor cell migration. Indeed, the intracellular signaling pathways also exert their final metastatic roles through regulation of extra cellular matrix (ECM). Therefore, it is required to assess the role of extra cellular components in biology of GC. Conclusion In the present review, we summarize 48 of the significant ECM components including 17 ECM modifying enzymes, seven extracellular angiogenic factors, 13 cell adhesion and cytoskeletal organizers, seven matricellular proteins and growth factors, and four proteoglycans and extra cellular glycoproteins. This review paves the way of determination of a specific extra cellular diagnostic and prognostic panel marker for the GC patients.

[PMID: 32365902 PMCID: PMC7246682 DOI: 10.3390/ijms21093175] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2020] [Revised: 04/24/2020] [Accepted: 04/29/2020] [Indexed: 12/15/2022] Open
Abstract
Embryo implantation is a complex process regulated by a network of biological molecules. Recently, it has been described that fractalkine (CX3CL1, FKN) might have an important role in the feto-maternal interaction during gestation since the trophoblast cells express fractalkine receptor (CX3CR1) and the endometrium cells secrete fractalkine. CX3CR1 controls three major signalling pathways, PLC-PKC pathway, PI3K/AKT/NFκB pathway and Ras-mitogen-activated protein kinases (MAPK) pathways regulating proliferation, growth, migration and apoptosis. In this study, we focused on the molecular mechanisms of FKN treatment influencing the expression of implantation-related genes in trophoblast cells (JEG-3) both in mono-and in co-culture models. Our results reveal that FKN acted in a concentration and time dependent manner on JEG-3 cells. FKN seemed to operate as a positive regulator of implantation via changing the action of progesterone receptor (PR), activin receptor and bone morphogenetic protein receptor (BMPR). FKN modified also the expression of matrix metalloproteinase 2 and 9 controlling invasion. The presence of HEC-1A endometrial cells in the co-culture contributed to the effect of fractalkine on JEG-3 cells regulating implantation. The results suggest that FKN may contribute to the successful attachment and implantation of embryo.

Kim H, Karadeniz F, Kong CS, Seo Y. Evaluation of MMP Inhibitors Isolated from Ligustrum japonicum Fructus. Molecules 2019; 24:molecules24030604. [PMID: 30744075 PMCID: PMC6384611 DOI: 10.3390/molecules24030604] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2019] [Revised: 01/24/2019] [Accepted: 01/31/2019] [Indexed: 11/16/2022] Open
Abstract
The current study investigated the ability of two secoiridoids, GL-3 (1) and oleonuezhenide (2), isolated from the fruits of Ligustrum japonicum to inhibit MMP-2 and -9 activity in phorbol 12-myristate 13-acetate (PMA)-induced HT-1080 human fibrosarcoma cells. Both compounds1 and 2 were able to exert lowered gelatin digestion activity for MMP-2 and -9 tested by gelatin zymography via suppressing the release of MMPs to culture medium according to ELISA results. Treatment with compounds was also able to suppress the expression of both mRNA and protein levels of MMP-2 and -9. Action mechanism behind the MMP inhibitory effect of the compounds was suggested to be via MAPK pathway indicated by decreased levels of phosphorylated p38, ERK and JNK proteins evaluated employing immunoblotting. Compound 1 was shown to be slightly more active to inhibit MMP-2 and -9, however, compound 2 showed more regular dose-dependency during inhibition. In conclusion, this study suggested that GL-3 and oleonuezhenide were notable natural origin potent MMP inhibitors and could serve as lead compounds for development of anti-invasive MMP inhibitors against tumor metastasis.

JOURNAL OF PHOTOCHEMISTRY AND PHOTOBIOLOGY B-BIOLOGY 2018; 185:241-253.

Abstract
Chronic exposure to ultraviolet (UV) radiation causes photo-oxidation, which in turn results in the upregulation of matrix metalloproteinases (MMPs) and loss of collagen. Rubus idaeus L. (RI), also called red raspberry, is an important cash crop that contains abundant antioxidant compounds. Sanguiin H-6 and lambertianin C are the major ingredients presented in the extracts. Here, we studied the protective effect of RI on UVB-induced photoaging in normal human dermal fibroblasts (NHDFs). We found that RI notably reduced UVB-induced MMPs secretion and pro-inflammatory mediators production, and significantly suppressed UVB-induced activation of mitogen-activated protein kinase (MAPK), nuclear factor-κβ, as well as activator protein 1. Additionally, treatment of NHDFs with the ERK inhibitor (PD98059) and JNK inhibitor (SP600125) resulted in the reduction of UVB-induced MMP-1 and IL-6 expressions, which demonstrated that the inhibition of MMP-1 and IL-6 by RI is associated with the MAPK pathway. Furthermore, we also found that RI accelerated procollagen type I synthesis by activating the transforming growth factor-β/Smad pathway and enhanced the expression of cytoprotective antioxidants such as heme oxygenase-1 and NHD(P)H quinone oxidoreductase 1 by promoting nuclear factor E2-related factor 2 nuclear transfer. Overall, these findings demonstrated that RI was potentially effective in preventing UVB induced skin photoaging.

Abstract
The extracellular-regulated kinases ERK1 and ERK2 are evolutionarily conserved, ubiquitous serine-threonine kinases that are involved in regulating cellular signaling in both normal and pathological conditions. Their expression is critical for development and their hyperactivation is a major factor in cancer development and progression. Since their discovery as one of the major signaling mediators activated by mitogens and Ras mutation, we have learned much about their regulation, including their activation, binding partners and substrates. In this review I will discuss some of what has been discovered about the members of the Ras to ERK pathway, including regulation of their activation by growth factors and cell adhesion pathways. Looking downstream of ERK activation I will also highlight some of the many ERK substrates that have been discovered, including those involved in feedback regulation, cell migration and cell cycle progression through the control of transcription, pre-mRNA splicing and protein synthesis.

Abstract
Limonium tetragonum has been well-known for its antioxidative properties as a halophyte. This study investigated the antimetastasis effect of solvent-partitioned L. tetragonum extracts (LTEs) and isolated compounds on HT1080 mouse melanoma cell model with a focus on matrix metalloproteinase (MMP) activity and TIMP and MAPK pathways. Upregulation and stimulation of MMPs result in elevated degradation of extracellular matrix which is part of several complications such as metastasis, cirrhosis, and arthritis. The anti-MMP capacity of LTEs was confirmed by their MMP-inhibitory effects, regulation of MMP and TIMP expression, and suppression of MAPK pathway. Among all tested LTEs, 85% aq. MeOH and n-BuOH were found to be most active fractions which later yielded two known flavonoid glycosides, myricetin 3-galactoside and quercetin 3-o-beta-galactopyranoside. Anti-MMP potential of the compounds was confirmed by their ability to regulate MMP expression through inhibited MAPK pathway activation. These results suggested that L. tetragonum might serve as a potential source of bioactive substances with effective anti-MMP properties.

Abstract
Background Dickkopf-4 (DKK4), a member of DKK family, appears to be a divergent protein. It remained multi-biological functions in carcinogenesis. The effect of DKK4 on the ovarian cancer cells remains unclear. This study detected the clinical significance of DKK4 in epithelial ovarian cancer (EOC) patients and its role in invasion. Methods QRT-PCR and western blot analysis were used to examine the levels of DKK4 mRNA and protein in 33 EOC tissues and 33 benign ovarian tumors. Immunohistochemical analysis was performed to assess DKK4 expression in 239 EOC samples. siRNA-mediated DKK4 silence was conducted. Transwell assay was used to detect the invasive ability. Phalloidin was used to stain the formations of actin filaments. Results The expressions of DKK4 mRNA and protein were elevated in EOC tissues as compared with those in benign ovarian tumors (p = 0.001 and <0.0001 respectively). Immunohistochemical results showed the strong expression of DKK4 protein was positively associated with late FIGO stage (p = 0.005) and poor disease free survival in univariate and multivariate analysis (p < 0.0001 and p = 0.001, respectively). SiRNA-mediated DKK4 knockdown inhibited cell invasive ability (all p < 0.0001) and the formations of actin filaments. DKK4 could promote the phosphration of c-JUN and JNK (p < 0.0001 and p = 0.001, respectively). Conclusions Our results indicated that DKK4 might be contributed to predicting EOC progression and prognosis. DKK4 could promote the invasion of EOC through JNK activation.

Abstract
Accumulating evidence shows that 18 β-glycyr-rhetinic acid (GRA) has antitumor activities in breast, ovarian cancer and leukemia, while its role in colorectal cancer remains unknown. In the present study, we investigated the effect of GRA in colorectal cancer cells LoVo, SW480 and SW620 and studied the underlying molecular mechanisms. Results showed that GRA had potent inhibitory effects on colorectal cancer cell proliferation in a dose- and time-dependent manner in vitro and in vivo. Growth inhibition was mediated by pro-apoptosis, as evident from Annexin V-FITC staining, the reduced expression of survivin and the induced expression of cleaved PARP. Furthermore, GRA treatment resulted in marked reduction of cell migration, invasion and wound healing capability, accompanying by the downregulated MMP expression. Moreover, GRA decreased the protein levels of p-PI3K, p-AKT, p-STAT3, p-JNK, p-p38 and p-NF-κB p65, of which the phosphorylation of PI3K and STAT3 decreased as early as 2 h after the GRA treatment. These results suggest that regulation of the apoptosis, invasion and migration of colorectal cancer cells by GRA might be through suppressing PI3K and STAT3 signaling pathways. the present study indicated that GRA could be a potential effective therapy for patients with colorectal cancer.

Abstract
Matrix metalloproteinases (MMPs) are crucial extracellular matrices degrading enzymes that take important roles in metastasis of cancer progression as well as other significant conditions such as oxidative stress and hepatic fibrosis. Natural products are on the rise for their potential to provide remarkable health benefits. In this context, halophytes have been of interest in the nutraceutical field with reported instances of isolation of bioactive compounds. In this study, Limonium tetragonum, an edible halophyte, was studied for its ability to inhibit MMP-2 and -9 using HT1080 fibrosarcoma cells. Results showed that L. tetragonum extract was able to inhibit the enzymatic activity and mRNA expression of MMP-2 and -9 according to gelatin zymography and RT-PCR assays, respectively, but it was not able to significantly change the MMP pathway related factors such as tissue inhibitors of metalloproteinases. Also, Mitogen-activated protein kinases pathway-related protein levels and their phosphorylation were assayed. While the phosphorylated p38 levels were decreased, extracellular signal-regulated kinase and c-Jun N-terminal kinase were not affected by L. tetragonum treatment. In conclusion, it was suggested that L. tetragonum contains substances acting as MMP inhibitors on enzymatic activity rather than intracellular pathway intervention, which could be useful for further utilization of L. tetragonum as a source for anti-MMP agents.

Abstract
Skin aging is the most readily observable process involved in human aging. Ultraviolet B (UVB) radiation causes photo-oxidation via generation of reactive oxygen species (ROS), thereby damaging the nucleus and cytoplasm of skin cells and ultimately leading to cell death. Recent studies have shown that high levels of solar UVB irradiation induce the synthesis of matrix metalloproteinases (MMPs) in skin fibroblasts, causing photo-aging and tumor progression. The MMP family is involved in the breakdown of extracellular matrix in normal physiological processes such as embryonic development, reproduction, and tissue remodeling, as well as in disease processes such as arthritis and metastasis. We investigated the effect of diphlorethohydroxycarmalol (DPHC) against damage induced by UVB radiation in human skin keratinocytes. In UVB-irradiated cells, DPHC significantly reduced expression of MMP mRNA and protein, as well as activation of MMPs. Furthermore, DPHC reduced phosphorylation of ERK and JNK, which act upstream of c-Fos and c-Jun, respectively; consequently, DPHC inhibited the expression of c-Fos and c-Jun, which are key components of activator protein-1 (AP-1, up-regulator of MMPs). Additionally, DPHC abolished the DNA-binding activity of AP-1, and thereby prevented AP-1-mediated transcriptional activation. These data demonstrate that by inactivating ERK and JNK, DPHC inhibits induction of MMPs triggered by UVB radiation.

Abstract
Ovarian cancer is the most lethal gynecologic malignancy worldwide. ETS homologous factor (EHF), a member of E26 transformation specific (ETS) transcription factors, has been reported overexpressed in ovarian cancer. However, the molecular mechanism underlying the biological function of EHF in ovarian cancer is still unclear. Here, we found that EHF was elevated in ovarian cancer tissues compared with non-tumorous tissues. Moreover, high EHF expression level was correlated with short survival time of patients with ovarian cancer. Knockdown of EHF in ovarian cancer cells, SKOV3 and OVCAR3, significantly inhibited cell proliferation and increased cells population in G1 phase. The proteins promoting cell cycles (Cyclin B1, Cyclin D1, and PCNA) were down-regulated and the protein negatively regulating cell cycle progression (P21) was up-regulated after EHF knockdown. Moreover, inhibition of EHF in ovarian cancer cells dramatically induced cell apoptosis, but impaired cell adhesion and cell invasion. Furthermore, phosphorylation levels of ERK and AKT were notably reduced in EHF knockdown cells. Finally, in vivo data showed that knockdown of EHF inhibited tumor growth in nude mice. Our data indicates that EHF could be a potential prognosis marker for ovarian cancer and work as an oncogene by targeting ERK and AKT signaling, which can serve as a new target for ovarian cancer treatment. © 2015 Wiley Periodicals, Inc.

Abstract
Ophiopogonin-D is one of steroidal saponins isolated from the root of the Chinese medicinal plant Ophiopogon japonicas. It has been claimed to possess anti-inflammatory and anti-oxidant properties. The present study was the first to examine the anti-tumor metastasis properties of ophiopogonin-D. An MTT assay showed that ophiopogonin-D inhibited the proliferation of MDA-MB-435 melanoma cells, and decreased invasion was demonstrated using a Transwell invasion assay. Furthermore, adhesion of MDA-MB-435 cells to human umbilical vascular endothelial cells and to fibronectin was inhibited by ophiopogonin-D. Gelatin zymography and western blot analysis showed that ophiopogonin-D inhibited the expression and secretion of matrix metalloproteinase-9 (MMP-9), but not that of MMP-2. Inhibition of phosphorylation of p38 by ophiopogonin-D indicated its inhibition of the mitogen-activated protein kinase pathway. Overall, the results suggested that ophiopogonin-D may be considered as a candidate drug for treating or preventing tumor metastasis.

Abstract
Purpose: Extracellular matrix metalloproteinase inducer (EMMPRIN) was reported to involve in the invasion and metastasis of malignancies by regulating the expression of vascular endothelial growth factor (VEGF) and matrix metalloproteinases (MMPs) in stromal and cancer cells. The study aimed to clarify the role of EMMPRIN expression in tumorigenesis and progression of ovarian epithelial carcinomas.
Methods: EMMPRIN siRNA were transfected into ovarian carcinoma cells with the phenotypes and their related molecules examined. EMMPRIN expression was determined in ovarian normal tissue, benign and borderline tumors, and epithelial carcinomas by real-time PCR, western blot, and immunohistochemisty.
Results: EMMPRIN siRNA treatment resulted in a lower growth, G1 arrest, apoptotic induction, decreased migration, and invasion. The transfectants showed reduced expression of Wnt5a, Akt, p70s6k, Bcl-xL, survivin, VEGF, and MMP-9 than mock and control cells at both mRNA and protein levels. According to real-time PCR and western blot, EMMPRIN mRNA or protein level was higher in ovarian borderline tumor and carcinoma than normal ovary and benign tumors (P < 0.05), and positively correlated with dedifferentiation and FIGO staging (P < 0.05). Immuhistochemically, EMMPRIN expression was positively correlated with FIGO staging, dedifferentiation, Ki-67 expression, the lower cumulative and relapse-free survival rate (P < 0.05).
Conclusions: Upregulated expression of EMMPRIN protein and mRNA might be involved in the pathogenesis, differentiation, and progression of ovarian carcinomas, possibly by modulating cellular events, such as proliferation, cell cycle, apoptosis, migration, and invasion.

Abstract
Attachment, spreading, and organization of endothelial cells into tubule networks are mediated by interactions between cells in the extracellular microenvironment. Laminins are key extracellular matrix components and regulators of cell adhesion, migration, and proliferation. In this study, laminin-derived peptides were conjugated to poly(ethylene glycol) (PEG) monoacrylate and covalently incorporated into degradable PEG diacrylate (PEGDA) hydrogels to investigate the influence of these peptides on endothelial cellular adhesion and function in organizing into tubule networks. Degradable PEGDA hydrogels were synthesized by incorporating a matrix metalloproteinase (MMP)–sensitive peptide, GGGPQGIWGQGK (abbreviated PQ), into the polymer backbone. The secretion of MMP-2 and MMP-9 by endothelial cells promotes polymer degradation and consequently cell migration. We demonstrate the formation of extensive networks of tubule-like structures by encapsulated human umbilical vein endothelial cells in hydrogels with immobilized synthetic peptides. The resulting structures were stabilized by pericyte precursor cells (10T1/2s) in vitro. During tubule formation and stabilization, extracellular matrix proteins such as collagen IV and laminin were deposited. Tubules formed in the matrix of metalloproteinase sensitive hydrogels were visualized from 7 days to 4 weeks in response to different combination of peptides. Moreover, hydrogels functionalized with laminin peptides and transplanted in a mouse cornea supported the ingrowth and attachment of endothelial cells to the hydrogel during angiogenesis. Results of this study illustrate the use of laminin-derived peptides as potential candidates for modification of biomaterials to support angiogenesis.

Abstract
4F2hc is a type-II glycoprotein whose covalent-bound association with one of several described light chains yields a heterodimer mainly involved in large neutral amino acid transport. Likewise, it is well known that the heavy chain interacts with β-integrins mediating integrin-dependent events such as survival, proliferation, migration and even transformation. 4F2hc is a ubiquitous protein whose overexpression has been related to tumor development and progression. Stable silencing of 4F2hc in HeLa cells using an artificial miRNA impairs in vivo tumorigenicity and leads to an ineffective proliferation response to mitogens. 4F2hc colocalizes with β1-integrins and CD147, but this interaction does not occur in lipid rafts in HeLa cells. Moreover, silenced cells present defects in integrin- (FAK, Akt and ERK1/2) and hypoxia-dependent signaling, and reduced expression/activity of MMP-2. These alterations seem to be dependent on the inappropriate formation of CD147/4F2hc/β1-integrin heterocomplexes on the cell surface, arising when CD147 cannot interact with 4F2hc. Although extracellular galectin-3 accumulates due to the decrease in MMP-2 activity, galectin-3 signaling events are blocked due to an impaired interaction with 4F2hc, inducing an increased degradation of β-catenin. Furthermore, cell motility is compromised after protein silencing, suggesting that 4F2hc is related to tumor invasion by facilitating cell motility. Therefore, here we propose a molecular mechanism by which 4F2hc participates in tumor progression, favoring first steps of epithelial-mesenchymal transition by inhibition of β-catenin proteasomal degradation through Akt/GSK-3β signaling and enabling cell motility.

Abstract
OBJECTIVES We evaluated the expression of extracellular matrix metalloproteinase inducer (EMMPRIN) and matrix metalloproteinase-2 (MMP-2) in nasopharyngeal carcinoma (NPC) and studied their relationship with cervical lymph node metastasis. METHODS Immunohistochemical staining was used to detect the expression of EMMPRIN and MMP-2 in specimens from patients with chronic nasopharyngitis (CN), nonmetastastic NPC (NM-NPC), and lymph node-metastatic NPC (LNM-NPC). RESULTS The rates of positive EMMPRIN expression in CN, NM-NPC, and LNM-NPC were 13.3%, 30.0%, and 66.7%, respectively. Significant differences were found between the rates in CN and LNM-NPC (p <0.01) and between the rates in NM-NPC and LNM-NPC (p = 0.01). In the LNM-NPC group, NPC cells had a higher rate of expression of EMMPRIN in tumor metastases than in the primary tumor (81.8% versus 66.7%; p = 0.01). The rates of positive MMP-2 expression in CN, NM-NPC, and LNM-NPC were 13.3%, 35.0%, and 60.6%, respectively. A significant difference was found between the rates in CN and LNM-NPC (p < 0.01). In the LNM-NPC group, NPC cells had a higher rate of MMP-2 expression in tumor metastases than in the primary tumor (72.7% versus 60.6%; p <0.01). The expressions of MMP-2 and EMMPRIN were highly correlated (rs = 0.466; p <0.01). CONCLUSIONS Nasopharyngeal carcinoma cells may attain enhanced metastastic capability through the expression of MMP-2 induced by EMMPRIN.

Abstract
Head and neck cancer is the sixth most common cancer in the world and most of them are squamous cell carcinomas. High frequency of cisplatin resistance in head and neck squamous cell carcinoma (HNSCC) leads to tumor relapse and irresponsiveness to cisplatin-based chemotherapy. However, the mechanisms underlying cisplatin resistance is still largely unrevealed. In this study, we found that CD147 was overexpressed in cisplatin-resistant HNSCC cell lines. Based on the result, CD147 expression was down-regulated in the cisplatin-resistant cell line and we observed that the sensitivity to cisplatin increased, as showed in the results of MTT assay and PI-staining apoptotic detection. Meanwhile, transfection of CD147 expression vector promoted the occurrence of cisplatin resistance in the cisplatin-sensitive cell line. Simultaneously blocking of uPAR with neutralizing antibody would significantly prevent the occurrence of cisplatin resistance induced by CD147 overexpression. In conclusion, our study finds that CD147 is also involved in mediating cisplatin resistance in HNSCC and uPAR serves as a possible candidate that collaborates with CD147 in this process.

Abstract
CD147 (alias emmprin or basigin), an integral plasma membrane glycoprotein and a member of the Ig superfamily, is widespread in normal tissues, but highly up-regulated in many types of malignant cancer cells. CD147 is multifunctional, with numerous binding partners. Recent studies suggest that complexes of CD147 with the hyaluronan receptor CD44 and associated transporters and receptor tyrosine kinases are enriched in the plasma membrane of cancer stem-like cells. Here, we show that subpopulations of tumor cell lines constitutively expressing high levels of cell-surface CD147 exhibit cancer stem-like cell properties; that is, they exhibit much greater invasiveness, anchorage-independent growth, spheroid formation, and drug resistance in vitro and higher tumorigenicity in vivo than those constitutively expressing low levels of cell-surface CD147. Primary CD147-rich cell subpopulations derived from mouse mammary adenocarcinomas also exhibit high levels of invasiveness and spheroid-forming capacity, whereas CD147-low cells do not. Moreover, localization at the plasma membrane of CD44, the EGF receptor, the ABCB1 and ABCG2 drug transporters, and the MCT4 monocarboxylate transporter is elevated in cells constitutively expressing high levels of cell-surface CD147. These results show that CD147 is associated with assembly of numerous pro-oncogenic proteins in the plasma membrane and may play a fundamental role in properties characteristic of cancer stem-like cells.

Abstract
OBJECTIVES MMP-1 is over-expressed in many cancers, with high expression often associated with poor survival. In the present study, we examined the expression of MMP-1 in EOC and its role in EOC invasion. Moreover, we evaluated the role of a newly identified MMP-1-protease activated receptor (PAR)-1 axis in LPA-induced EOC invasion. METHODS MMP-1 and PAR1 mRNA expression in EOC cell lines was determined by real time PCR. MMP-1 mRNA expression in 96 normal and carcinoma ovarian tissue specimens was analyzed using a TissueScan real time PCR array. MMP-1 concentration in conditioned medium was measured by MMP-1 ELISA. PAR1 protein expression was detected by Western blotting. Cell invasion was evaluated by in vitro Matrigel invasion assay. RESULTS In ovarian tumor tissues more MMP-1 expression was observed than in normal ovarian tissues (p<0.05), and its expression correlated with tumor grade (grade 3>grade 2>grade 1). Human recombinant MMP-1 as well as serum free conditioned medium containing high levels of MMP-1 from DOV13 and R182 cells significantly promoted DOV13 cell invasion (p<0.05), implicating a direct role of MMP-1 in EOC invasion. Moreover, MMP-1 induced DOV13 invasion was significantly blocked by PAR1 siRNA silencing. Furthermore, MMP-1 and PAR1 were both significantly induced by LPA (20 μM), and siRNA silencing of MMP-1 and PAR1 both significantly reduced LPA's invasion-promoting effect in DOV13 cells (p<0.05). CONCLUSIONS Our results suggest that the MMP-1-PAR1 axis is involved in EOC invasion and at least partially mediates LPA-induced EOC invasion. Therefore, blocking MMP-1 or PAR1 may represent a new therapeutic option for metastatic EOC.

Abstract
PURPOSE Extracellular matrix metalloproteinase inducer (EMMPRIN) was reported to involve in the invasion and metastasis of malignancies by regulating the expression of vascular endothelial growth factor (VEGF) in stromal and cancer cells. The study aimed to clarify the role of EMMPRIN expression in tumorigenesis and progression of colorectal carcinomas (CRC). METHODS EMMPRIN expression was examined on tissue microarray containing colorectal carcinomas, adenoma and non-neoplastic mucosa (NNM) by immunohistochemistry and in situ hybridization (ISH). Colorectal carcinoma cell lines (DLD-1, HCT-15, SW480 and WiDr) and tissues were studied for EMMPRIN expression by Western blot or RT-PCR, followed by sequencing. RESULTS All carcinoma cell lines showed EMMPRIN expression at both mRNA and protein levels. Two synonymous mutations were found in carcinoma cell lines at codon109 (GCT → GCC: Ala) or 179 (GAT → GAC: Asp). Frozen CRC tissues displayed higher EMMPRIN expression than paired NNM (P < 0.05). EMMPRIN expression was immunohistochemically stronger in colorectal high-grade adenoma, adenocarcinoma and metastatic carcinoma than non-neoplastic superficial epithelium and low-grade adenoma (P < 0.05). In contrast, its mRNA level was similar from colorectal NNM, adenoma to adenocarcinoma by ISH, in line with the findings of RT-PCR (P > 0.05). Immunohistochemically, EMMPRIN expression was positively correlated with tumor size, depth of invasion, vascular or lymphatic invasion, grade of infiltration (INF), ki-67 and VEGF expression of CRCs (P < 0.05). Among them, depth of invasion was an independent associated factor for EMMPRIN expression in CRCs (P < 0.05). CONCLUSIONS Up-regulated EMMPRIN protein expression might contribute to colorectal carcinogenesis without the alteration of its glycosylation and mRNA level. Aberrant EMMPRIN protein expression might promote growth or invasion of CRCs possibly through increased ki-67 expression and inducible angiogenesis via up-regulating VEGF expression.

Abstract
Neuroblastoma tumors are derived from the neural crest and exhibit substantial phenotypic heterogeneity and various degrees of differentiation and maturation. The identification of new cell surface markers in neuroblastoma has relevance to disease classification and therapy. As a means to categorize neuroblastomas based on cell surface protein expression, we have obtained a comprehensive profile of the cell surface proteome of the MYCN nonamplified SH-SY5Y neuroblastoma cell line. Biotinylated cell surface proteins were captured using an avidin affinity column, fractionated by reversed-phase chromatography and subjected to in-depth analysis by LC-MS/MS. An extensive list of proteins was established and a subset of surface membrane proteins was assessed by immunohistochemistry in a set of neuroblastoma tissue microarrays. Among identified proteins tested, NCAM and CD147 exhibited increased expression in poorly differentiated tumors (p < 0.01 and <0.03, respectively). CD147 expression was previously associated with aggressive carcinomas but has not been described in neuroblastoma. This comprehensive neuroblastoma cell surface profile has identified novel potential markers for neuroblastoma classification and novel potential targets for therapy.

Abstract
Many investigators have indicated that overexpression and amplification of matrix metalloproteinase 2 (MMP-2) and extracellular matrix metalloproteinase inducer (EMMPRIN) are independent prognostic factors for primary tumors. We studied expression of them in tissues from intrahepatic cholangiocarcinoma (IHCCA) and normal bile ducts, and discussed the occurrence and development of IHCCA. Another goal was to explore possible association of MMP-2 and EMMPRIN with clinicopathologic parameters and prognosis of IHCCA. MMP-2 and EMMPRIN expression in 106 cases of IHCCA tissues and 15 cases of normal bile ducts were examined by immunohistochemical staining. Then, the association of MMP-2 and EMMPRIN expression with clinicopathologic parameters and patients' prognosis was analyzed. The positive expression levels of MMP-2 and EMMPRIN associated significantly with various clinicopathologic risk factors, such as poor histologic differentiation (p = 0.03, 0.02), higher TNM stages (p = 0.02, 0.01) and decreased tumor-specific survival. In particular, the tumor-specific survival rate of the patients with MMP-2+/ EMMPRIN+expression was the lowest (p < 0.01). Using Cox regression analysis of the 89 patients, the conjoined expressions of MMP-2-/ EMMPRIN-, MMP-2+/ EMMPRIN +, histologic differentiation, and the clinical TNM stages of tumorous tissues were independent prognostic indicators of IHCCA (p < 0.01, p < 0.01, p = 0.02, p = 0.01 and p = 0.01, respectively). MMP-2 and EMMPRIN expression in primary tumor predicts an unfavorable prognosis in IHCCA, suggesting a crucial role of the two markers in progression of human IHCCA.

Abstract
Ovarian carcinomas are a heterogeneous group of neoplasms and are traditionally subclassified based on type and degree of differentiation. Although current clinical management of ovarian carcinoma largely fails to take this heterogeneity into account, it is becoming evident that each major histological type has characteristic genetic defects that deregulate specific signaling pathways in the tumor cells. Moreover, within the most common histological types, the molecular pathogenesis of low-grade versus high-grade tumors appears to be largely distinct. Mouse models of ovarian carcinoma have been developed that recapitulate many of the morphological features, biological behavior, and gene-expression patterns of selected subtypes of ovarian cancer. Such models will likely prove useful for studying ovarian cancer biology and for preclinical testing of molecularly targeted therapeutics, which may ultimately lead to better clinical outcomes for women with ovarian cancer.

Abstract
Multidrug resistant (MDR) tumor cells over-expressing P-glycoprotein exhibit variation in invasive behavior. To investigate the mechanisms, we analyzed the expression of CD147. The results showed that CD147 expression was increased in HepG2/Adr cells, as compared to HepG2 cells. The MDR cells produced more MMP11 and MDR1, which promoted HepG2/Adr cells invasion and increased resistance to chemotherapeutic drugs. On the other hand, CD147 silencing in HepG2/Adr cells by RNAi led to the opposite effect. Treatment of tumor cells with U-0126, an inhibitor of MAPK/Erk, also down-regulated MMP11 and MDR1 expression. Thus, CD147 may functionally mediate tumor cells invasion and MDR.

Abstract
Extracellular matrix metalloproteinase inducer (EMMPRIN/CD147) is a multifunctional membrane glycoprotein overexpressed in many solid tumors, and involved in tumor invasion and angiogenesis. We investigated EMMPRIN expression in human prostate cancer (CaP) tissues and cells, and evaluated whether EMMPRIN expression is related to tumor progression and matrix metalloproteinase (MMPs) expression in human CaP. An immunohistochemical study using tissue microarrays of 120 primary CaPs of different grades and 20 matched lymph node metastases from untreated patients was performed. The association of EMMPRIN expression with clinicopathological parameters was evaluated. Co-immunolocalization for EMMPRIN and MMP-1, MMP-2 or MMP-9 in primary tumors was examined using confocal microscopy. Flow cytometry and immunoblotting were used to examine EMMPRIN expression in 11 metastatic CaP cell lines. Heterogeneous expression of EMMPRIN was found in 78/120 (65%) CaPs, correlated significantly with progression parameters including pre-treatment PSA level (P < 0.05) and increased with progression of CaP (Gleason score, P < 0.05; pathological stage, P < 0.01; nodal involvement, P < 0.05 and surgical margin, P < 0.05). Heterogeneous cytoplasmic MMP-1, MMP-2 and MMP-9 associated with EMMPRIN immunolabeling was observed, particularly in tumors with Gleason scores >3 + 4. Metastatic CaP cell lines, except DuCaP, expressed abundant EMMPRIN protein, indicating highly ( approximately 45 to approximately 65 kDa) and less ( approximately 30 kDa) glycosylated forms, although with no relationship to cells being either androgen responsive or nonresponsive. Our results suggest that EMMPRIN may regulate MMPs and be involved in CaP progression, and as such, could provide a target for treating metastatic CaP disease.

Abstract
OBJECTIVE CD147 is one of the molecules involved in regulating the expression of matrix metalloproteinases (MMPs). The goal of this study was to analyze the expression levels of CD147 and MMP-2 in differentiated thyroid carcinomas (DTCs) tissues, as well as their associations with the clinicopathologic features of DTC patients. METHODS CD147 and MMP-2 expression in 156 patients who underwent operation for DTC (100 with papillary thyroid carcinomas and 56 with follicular thyroid carcinomas) were examined by immunostaining on paraffin-embedded tumor specimens. The Spearman correlation was calculated between the expression levels of CD147 and MMP-2 in DTC tissues. Then, the association of their expression with clinicopathologic characteristics was analyzed. RESULTS CD147 and MMP-2 were expressed mainly in cancerous lesions, but also expressed in some normal tissues. A total of 55 and 58 in 156 (35.26 and 37.18%, respectively) cases showed low CD147- and MMP-2-positive expression; 52 and 50 in 156 (33.33 and 32.05%, respectively) cases showed intermediate CD147- and MMP-2-positive expression and 49 and 48 in 156 (31.41 and 30.77%, respectively) cases showed high CD147- and MMP-2-positive expression. The Spearman analysis indicated that the expression level of CD147 was positively correlated with that of MMP-2 significantly (rs = 0.86, P = 0.02). Positive CD147 and MMP-2 immunostaining associated significantly with extrathyroidal invasion (P = 0.02, 0.03), lymph node metastasis (P = 0.01, 0.01) and depth of tumor invasion (P < 0.01, =0.01). CONCLUSIONS The results have been demonstrated that the expression of CD147 and MMP-2 may be an important feature of DTC. The detection of these two markers may increase the ability of clinicians to investigate the progression of DTC patients.

Abstract
The immunoglobulin superfamily member CD147 plays an important role in fetal, neuronal, lymphocyte and extracellular matrix development. Here we review the current understanding of CD147 expression and protein interactions with regard to CD147 function and its role in pathologic conditions including heart disease, Alzheimer's disease, stroke and cancer. A model linking hypoxic conditions found within the tumor microenvironment to upregulation of CD147 expression and tumor progression is introduced.

Abstract
Multidrug resistant (MDR) cancer cells overexpressing P-glycoprotein (P-gp) display variations in invasive and metastatic behavior. We aimed to clarify the mechanism(s) underlying this observation and transfected vectors carrying CD147, a glycoprotein enriched on the surface of tumor cells that stimulates the production of matrix metalloproteinases (MMPs), and specific shCD147 into MCF7 and MCF7/Adr cells, respectively. Using quantitative real-time polymerase chain reaction and Western blot, we found that overexpression of CD147 in MCF7 cells up-regulated MDR1, MMP2, and MMP9 on both transcription and expression levels, which promoted tumor cells metastasis and conferred them multidrug resistance to P-gp substrate drugs, as determined by in vitro invasion assay and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. On the other hand, silencing of CD147 in MCF7/Adr cells led to the opposite effect. Moreover, Erk1/2 in CD147-overexpressing clones were observed to be highly activate and after treatment with U0126, an Erk1/2-specific inhibitor, the expression of MDR1, MMP2 and MMP9 were decreased significantly. Thus, CD147 may assume a dual role, since it had intrinsic stimulative effects on tumor invasion in vitro as well as increasing resistance to P-gp substrate drugs.

Abstract
HAb18G/CD147 has been identified as a factor that induces MMPs production. SiRNA targeted against HAb18G/CD147 was transfected into FHCC-98 cells (a HCC cell line) to knockdown its expression. The results showed that downregulating HAb18G/CD147 decreased ERK1/2, MMP-2 and FAK levels and inhibited cell motility and invasion, together with rearranged actin stress fiber formation, while had no effects on integrin alpha3beta1 expression. MEK1/2 inhibitor, U0126, inhibited MMP-2, FAK and actin expression in FHCC-98 cell line. The findings indicate that si-HAb18G inhibits gelatinase production, actin and FAK expression in FHCC-98 via an ERK1/2 signaling pathway.

Abstract
After an injury to the adult mammalian central nervous system (CNS), a variety of growth-inhibitory molecules are upregulated. A glial scar forms at the site of injury and is composed of numerous molecular substances, including chondroitin sulfate proteoglycans (CSPGs). These proteoglycans inhibit axonal growth in vitro and in vivo. Matrix metalloproteinases (MMPs) can degrade the core protein of some CSPGs as well as other growth-inhibitory molecules such as Nogo and tenascin-C. MMPs have been shown to facilitate axonal regeneration in the adult mammalian peripheral nervous system (PNS). This review will focus on the various roles of proteoglycans and MMPs within the injured nervous system. First, we will present a general background on the injured central nervous system and explore the roles that proteoglycans play in the injured PNS and CNS. Second, we will discuss the various functions of MMPs within the injured PNS and CNS. Special attention will be paid to the possibility of how MMPs might modify the growth-inhibitory extracellular environment of the injured adult mammalian spinal cord and facilitate axonal regeneration in the CNS.

Abstract
Tumour growth depends on angiogenesis, which is closely associated with vascular endothelial growth factor (VEGF) and matrix metalloproteinases (MMPs). Extracellular MMP inducer (EMMPRIN) was reported to involve in the progression of malignancies by regulating expression of VEGF and MMPs in stromal cells. To clarify the role of EMMPRIN in progression and angiogenesis of gastric carcinoma, expression of EMMPRIN, ki-67, MMP-2, MMP-9 and VEGF was examined on tissue microarray containing gastric carcinomas (n=234) and non-cancerous mucosa adjacent to carcinoma (n=85) by immunohistochemistry. Additionally, microvessel density (MVD) was assessed after labelling with anti-CD34 antibody. Extracellular MMP inducer expression was compared with clinicopathological parameters of tumours, including levels of ki-67, MMP-2, MMP-9 and vascular endothelial growth factor (VEGF), MVD as well as survival time of carcinoma patients. Gastric carcinoma cell lines (HGC-27, MKN28 and MKN45) were studied for EMMPRIN expression by immunohistochemistry and Western blot. Extracellular MMP inducer expression was gradually increased from normal mucosa to carcinomas through hyperplastic or metaplastic mucosa of the stomach (P<0.05). There was strong EMMPRIN expression in all gastric carcinoma cell lines despite different levels of glycosylation. Extracellular MMP inducer expression was positively correlated with tumour size, depth of invasion, lymphatic invasion, expression of ki-67, MMP-2, MMP-9 and VEGF of tumours (P<0.05), but not with lymph node metastasis, UICC staging or differentiation (P>0.05). Interestingly, there was a significantly positive relationship between EMMPRIN expression and MVD in gastric carcinomas (P<0.05). Survival analysis indicated EMMPRIN expression to be negatively linked to favourable prognosis (P<0.05), but not be independent factor for prognosis (P>0.05). Further analysis showed three independent prognostic factors, depth of invasion, lymphatic and venous invasion, to influence the relationship between EMMPRIN expression and prognosis. Upregulated expression of EMMPRIN possibly contributes to genesis, growth and local invasion of gastric carcinomas. Altered EMMPRIN expression might enhance growth, invasion and angiogenesis of gastric carcinoma via upregulating MMP expression of both stromal fibroblasts and gastric cancer cells and could be considered as an objective and effective marker to predict invasion and prognosis.

Abstract
Signaling pathways regulating cell proliferation and survival have become attractive targets for anticancer strategies. In the present study, we analyzed by immunohistochemistry, a panel of benign nevi, superficial spreading and nodular primary melanomas and metastases for expression of activated p38/mitogen-activated protein kinase (p-p38) and c-jun N-terminal kinase (JNK) (p-JNK) and correlated the findings with known prognostic variables. Twenty-five and 35% of the primaries and 9 and 25% of the metastases expressed variable levels of p-p38 and p-JNK, respectively. In benign nevi, 73.5% expressed p-JNK and 7% expressed p-p38. For patients with superficial spreading melanomas, high level of cytoplasmic p-JNK was associated with thicker tumors (P=0.017) and shorter disease-free survival (P=0.003) as well as with markers of cell proliferation (cyclin A (P=0.017) and p21 (P=0.021)). In nodular melanomas, nuclear p-p38 was associated with Ki-67 (P=0.012), but neither cytoplasmic nor nuclear localized p-p38 was associated with disease outcome. Of note, in superficial spreading melanomas, a positive correlation between cytoplasmic p-JNK and cytoplasmic p-extracellular signal-regulated kinase ERK(1/2) (P=0.005) and p-p38 (P=0.003) was observed. Likewise, p-p38 in cytoplasm was positively associated with cytoplasmic p-ERK1/2 (P<0.0005) and p-Akt (P=0.047). In contrast, except for a positive correlation between nuclear p-p38 and membranous p-TrkA (P=0.02), no correlation between the activation status of the different signaling pathways was observed in nodular melanomas. In conclusion, our results suggest that in benign nevi activated JNK may have a role in restricting uncontrolled cell proliferation or survival. However, during tumor progression, activation of JNK is associated with cell proliferation and shorter relapse-free period for patients with superficial spreading melanomas, suggesting that the JNK activation status could be a marker for clinical outcome in at least a subgroup of malignant melanoma. In contrast, activation of p38 seems to play a less important role in development and progression of malignant melanomas.

Abstract
OBJECTIVE To analyze the expression of phospholipase A2 (PLA2) isoforms and its relationship with matrix metalloproteinase (MMP) expression and clinical parameters in advanced-stage (FIGO III-IV) ovarian carcinoma. METHODS Seventy-seven fresh frozen effusions from ovarian carcinoma patients were studied for messenger RNA (mRNA) expression of 10 secretory PLA2 (sPLA2) isoforms (IB, IIA/D/E/F, III, V, X, XII and XIII), the PLA2 receptor (sPLA2R), cytoplasmic PLA2 (cPLA2), PLA2-activating protein (PLAP) and MMP-2 using reverse transcription polymerase chain reaction (RT-PCR). Phosphorylated cPLA2 (p-cPLA2) protein expression was studied in 52 effusions using immunohistochemistry. MMP-2 and MMP-9 activity was evaluated in 22 and 20 effusions, respectively, using zymography. Expression was analyzed for correlation with clinicopathologic parameters, chemotherapy status and survival. RESULTS PLA2 isoforms, sPLA2R, PLAP and MMP-2 mRNA was expressed in >95% of specimens. p-cPLA2 protein was expressed in 46/52 (88%) effusions. MMP-2 activity was found in all specimens, while that of MMP-9 was detected in 19/20 effusions. MMP-2 was found to be co-expressed with p-cPLA2 (p=0.003) and sPLA2-IIA (p=0.021). Lower expression of sPLA2-IIA (p<0.001) and higher expression of sPLA2-V (p=0.038) and sPLA2-XIII (p=0.001) was found in post-chemotherapy effusions. In univariate survival analysis, higher levels of sPLA2-V correlated with better overall (OS, p=0.021) and progression-free (PFS, p=0.025) survival. For patients with post-chemotherapy effusions, FIGO stage IV and higher PLAP mRNA expression correlated with worse OS (p=0.005 for both PLAP and stage), while higher PLAP (p=0.025) and sPLA2-XII (p=0.027) levels and FIGO stage IV (p<0.001) correlated with shorter PFS. In Cox multivariate analysis, PLAP expression (p=0.022) and FIGO stage (p=0.036) independently predicted poor OS, while higher sPLA2-XII levels (p=0.04) and FIGO stage (p=0.003) were independent predictors of shorter PFS. CONCLUSIONS The present study documents for the first time expression of PLA2 isoforms, sPLA2R and PLAP in ovarian carcinoma. PLA2 isoenzyme expression differs in pre- and post-chemotherapy specimens. PLAP and sPLA2-XII may be independent predictors of poor outcome for patients with post-chemotherapy effusions.

Abstract
OBJECTIVE To characterize the expression of basigin in ovarian endometriotic tissue, normal ovary, and endometrium during the menstrual cycle. DESIGN Controlled, retrospective study for evaluation of basigin expression in archived specimens. SETTING Academic research environment: University of Kentucky College of Medicine. PATIENT(S) Archived surgical specimens selected by retrospective chart review of age-matched (39 +/- 2.5 years) patients with and without ovarian endometriosis. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Expression localization of basigin mRNA and protein. RESULT(S) Basigin (mRNA and protein) was localized to granulosa cells (follicles of all stages), the ovarian surface epithelium, and granulosa and theca lutein of corpora lutea. Differential patterns of expression were apparent among samples of eutopic endometrium collected during the proliferative and secretory stages. In endometriotic lesions on the ovary, basigin was detected in the glandular epithelia and stroma of proliferative and secretory phase samples, but patterns of expression were unsynchronized with those of the eutopic endometrium from the same patient. CONCLUSION(S) The current data demonstrate unique expression patterns of basigin in the human ovary and endometriotic tissue, thereby supporting a possible role in normal ovarian function and in the dysregulation of proteolytic matrix metalloproteinases in endometriosis.
