Abstract
Background Local anesthesia can reduce the response to surgical stress and decrease the consumption of opioids, which may reduce immunosuppression and potentially delay postoperative tumor recurrence. We compared paravertebral block (PVB) combined with general anesthesia (GA) and general anesthesia regarding their effects on postoperative pain and matrix metalloproteinase-9 (MMP-9) after video-assisted thoracoscopic surgery (VATS) lobectomy. Methods 54 patients undergoing elective VATS lobectomy at a single tertiary care, teaching hospital located in Qingdao between May 2, 2018 and Sep 28, 2018 were randomised by computer to either paravertebral block combined with general anesthesia or general anesthesia. The primary outcomes were pain scores at rest and on cough at 1, 4, 24, and 48 h after surgery. The secondary outcome were plasma concentrations of MMP-9, complications, and length of postoperative hospital stay. Results 75 were enrolled to the study, of whom 21 were excluded before surgery. We analyzed lobectomy patients undergoing paravertebral block combined with general anesthesia (n = 25) or general anesthesia (n = 24). Both groups were similar regarding baseline characteristics. Pain scores at rest at 4 h and 24 h, on cough at 4 h were lower in PVB/GA group, compared with GA group (P < 0.05). There were no difference in pain scores at rest at 1 h, 48 h and on cough at 1 h, 24 h, and 48 h between groups. Patients in the PVB/GA group showed a greater decrease in plasma MMP-9 level at T1 and T2 after VATS lobectomy (P < 0.05). Postoperative complications and length of stay did not differ by anesthetic technique. Conclusions The paravertebral block/general anesthesia can provide statistically better pain relief and attenuate MMP-9 response to surgery and after VATS lobectomy. This technique may be beneficial for patients to recover rapidly after lung surgery and reduce postoperative tumor recurrence. Trial registration Chinese Clinical Trial registration number ChiCTR1800016379. Registered 28 May 2018.

Abstract
Aims and Background Matrix metalloproteinase (MMP) family member MMP-9 degrades type IV collagen, which is one of the main constituents of the basement membrane. MMP-9 is closely associated with the invasive and metastatic potential of most types of lung cancer. In this study we investigated the levels of MMP-9 in serum and bronchial lavage fluid from lung cancer patients and compared them with the levels in patients with nonmalignant lung disease. We also attempted to clarify the possible relationship between serum and bronchial lavage fluid MMP-9 levels and histopathology, staging and metastasis of lung cancer. Study Design The study group consisted of 34 patients with lung cancer. The control group comprised 21 patients with nonmalignant lung disease. MMP-9 levels in serum and bronchial lavage fluid were evaluated by ELISA. Results MMP-9 levels in serum samples from the group with malignant disease were significantly higher than those from the control group (P <0.05). Bronchial lavage MMP-9 levels did not differ significantly between the two groups (P >0.05). Serum MMP-9 levels were two-fold higher than those in bronchial lavage, but there was no correlation between bronchial lavage and serum levels in both groups (r = 0.18, P >0.05). In the group with malignant disease, MMP-9 levels in serum and bronchial lavage fluid did not show any relationship with histopathological type and tumor stage. There was a statistically significant correlation between serum MMP-9 levels and local tumor stage in smoking nonsmall cell lung cancer (NSCLC) patients (r = 0.33, P <0.05). Karnofsky scores of lung cancer patients were inversely correlated with MMP-9 levels of serum (r = -0.39, P <0.05) but not of bronchial lavage fluid. Conclusion From our data it can be concluded that MMP-9 levels of serum but not of bronchial lavage fluid can be helpful in differentiating between malignant and benign lung diseases, and are related to the local stage in NSCLC patients and general clinical status of lung cancer patients.

Abstract
Introduction: To estimate the efficacy and safety of vascular endothelial growth factor receptor tyrosine kinase inhibitors (VEGFR-TKIs) in combination with chemotherapy for patients with advanced non-small cell lung cancer (NSCLC). Methods: We searched PubMed, PMC database, EMBASE, EBSCO-Medline, Cochrane Central Register of Controlled Trials (CENTRAL), American Society of Clinical Oncology (ASCO), International Association for the Study of Lung Cancer (IASLC) and the European Society of Medical Oncology (ESMO), http://www.clinicaltrials.gov/, CNKI, and Wanfang databases to identify primary research reporting the survival outcomes and safety of VEGFR-TKIs in patients with advanced NSCLC. A meta-analysis was conducted to generate combined hazard ratios (HRs) with 95% confidence intervals (CI) for overall survival (OS), progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR), and risk ratios (RRs) with 95% CI for adverse events (AEs). Results: A total of 20 RCTs (8,366 participants) were included. The VEGFR-TKIs resulted in improved PFS (HR 0.82, 95% CI 0.78-0.87), ORR (HR 1.72, 95% CI 1.34-2.22), and DCR (1.45, 1.26-1.67) in patients with advanced NSCLC, but had no impact on OS (HR 0.94, 95% CI 0.89-1.00). The incidence of some high grade (≥ 3) AEs increased, such as hemorrhage, hypertension and neutropenia. Conclusions: Our study demonstrated that regimens with VEGFR-TKIs combined with chemotherapy improved PFS, ORR and DCR in patients with advanced NSCLC, but had no impact on OS. VEGFR-TKIs induced more frequent and serious AEs compared with control therapies.

Abstract
Lung squamous cell carcinoma (SCC) accounts for a considerable proportion of lung cancer cases, but there is still a lack of effective therapies. FGFR1 amplification is generally considered a promising therapeutic target. Honokiol is a chemical compound that has been proven to be effective against various malignancies and whose analog has been reported to target the mitogen‐activated protein kinase family, members of a downstream signaling pathway of FGFR1. This was an explorative study to determine the mechanism of honokiol in lung SCC. We found that honokiol induced apoptosis and cell cycle arrest in lung SCC cell lines in a time‐ and dose‐dependent manner. Honokiol also restricted cell migration in lung SCC cell lines. Moreover, the expression of FGF2 and the activation of FGFR1 were both downregulated by honokiol. Pharmacological inhibition and siRNA knockdown of FGFR1 induced apoptosis in lung SCC cells. Our in vivo study indicated that honokiol could suppress the growth of xenograft tumors, and this effect was associated with the inhibition of the FGF2‐FGFR1 signaling pathway. In conclusion, honokiol induced cell apoptosis in lung SCC by targeting the FGF2‐FGFR1 autocrine loop.

Abstract
BACKGROUND Anlotinib (AL3818) is a novel multitarget tyrosine kinase inhibitor, inhibiting tumour angiogenesis and proliferative signalling. The objective of this study was to assess the safety and efficacy of third-line anlotinib for patients with refractory advanced non-small-cell lung cancer (RA-NSCLC). METHODS Eligible patients were randomised 1 : 1 to receive anlotinib (12 mg per day, per os; days 1-14; 21 days per cycle) or a placebo. The primary end point was progression-free survival (PFS). RESULTS A total of 117 eligible patients enrolled from 13 clinical centres in China were analysed in the full analysis set. No patients received immune check-point inhibitors and epidermal growth factor receptor status was unknown in 60.7% of the population. PFS was better with anlotinib compared with the placebo (4.8 vs 1.2 months; hazard ratio (HR)=0.32; 95% confidence interval (CI), 0.20-0.51; P<0.0001), as well as overall response rate (ORR) (10.0%; 95% CI, 2.4-17.6% vs 0%; 95% CI, 0-6.27%; P=0.028). The median overall survival (OS) was 9.3 months (95% CI, 6.8-15.1) for the anlotinib group and 6.3 months (95% CI, 4.3-10.5) for the placebo group (HR=0.78; 95% CI, 0.51-1.18; P=0.2316). Adverse events were more frequent in the anlotinib than the placebo group. The percentage of grade 3-4 treatment-related adverse events was 21.67% in the anlotinib group. CONCLUSIONS Anlotinib as a third-line treatment provided significant PFS benefits to patients with RA-NSCLC when compared with the placebo, and the toxicity profiles showed good tolerance.

Abstract
Matrix metalloproteinases-9 (MMP-9) was one of the most important enzyme to breakdown extracellular matrix, aim to clarify the prognostic value of MMP-9 in non-small cell lung cancer (NSCLC), we investigated the serum MMP-9 of NSCLC patients and performed a meta-analysis of the published literature. The expression and activity of serum MMP-9 were assessed by ELISA and gelatin zymography in 163 NSCLC patients. Moreover, 26 studies were included in meta-analysis by searching Medline and ISI Web of Knowledge. Our own data revealed high activity but not expression of MMP-9 significantly correlated with advanced T category and positive metastasis. In contrast, the meta-analysis revealed that increased MMP-9 level indicate high T category (RR = 0.83, 95% CI: 0.73-0.94), tumor stage (RR = 0.72, 95% CI: 0.63-0.82) and poor OS (5-year overall survival, RR = 1.32, 95% CI: 1.19-1.48). Moreover, stratified analysis based on sample types found that high MMP-9 expression in tissue specimen but not serum was significant correlated with advanced T category (RR = 0.81, 95% CI: 0.72-0.92), tumor stage (RR = 0.69, 95% CI: 0.60-0.80) and poor 5-year OS (1.33, 95% CI: 1.18-1.50).In conclusion, the activity of MMP-9 was positively correlated with advanced T category and distant metastasis. Moreover, the meta-analysis revealed that overexpression of MMP-9 in tissue but not in serum was a risk factor of advanced T category, tumor stage and poor outcome.

Abstract
Lung cancer is one of the major causes of cancer-related mortality worldwide, and non-small-cell lung cancer is the most common form of lung cancer. Several studies had shown that thalidomide has potential for prevention and therapy of cancer. Therefore, the current study aimed to investigate the antitumor effects of two novel thalidomide analogs in human lung cancer A549 cells. The antiproliferative, antimigratory, and apoptotic effects in A549 cells induced by thalidomide analogs were examined. In addition, their effects on the expression of mRNAs encoding vascular endothelial growth factor165 (VEGF165) and matrix metalloproteinase-2 (MMP-2) were evaluated. Their influence on the tumor volume in nude mice was also determined. Results revealed that thalidomide analogs exhibited antiproliferative, antimigratory, and apoptotic activities with more pronounced effect than thalidomide drug. Furthermore, analogs 1 and 2 suppressed the expression levels of VEGF165 by 42% and 53.2% and those of MMP-2 by 45% and 52%, respectively. Thalidomide analogs 1 and 2 also reduced the tumor volume by 30.11% and 53.52%, respectively. Therefore, this study provides evidence that thalidomide analogs may serve as a new therapeutic option for treating lung cancer.

Abstract
Background The major pathological type of non-small cell lung cancer is lung adenocarcinoma (LAC), which has a poor prognosis. BRCA1-associated protein-1 (BAP1) is a newly identified tumor suppressor that regulates a number of cellular functions in somatic malignancies. However, the impact of BAP1 expression in LAC has not been investigated. Methods A total of 112 cases of LAC and 101 cases of non-neoplastic lung diseases were included in this study. The study focused on BAP1 expression in lung tissues and its relationship to patients’ clinical and pathological features. BAP1 expression was detected by immunohistochemistry. A human LAC cell line NCI-H1299 was transfected with lipofectamine p3xFLAG-BAP1. BAP1 gene expression was silenced in another LAC cell line NCI-H1650, in order to test the inhibitory effect of BAP1 on cell migration and invasion, as well as cell cycle regulation. Results BAP1 expression showed a negative correlation with tumorigenesis of LAC (p <0.001) and lymph node metastasis (p = 0.010). High expression of BAP1 predicted longer disease free survival (p = 0.040) and overall survival (p = 0.021) of LAC patients. In functional assays, BAP1 was found to inhibit the migration and invasion of LAC cells, and promoted their apoptosis and necrosis. Conclusions We identify BAP1 as a LAC precursor as well as a robust prognostic indicator in LAC patients. This study provides in vitro rationale for the further investigation of BAP1 in preclinical studies.

Abstract
The development and maintenance of an adequate vascular supply is critical for the viability of normal and neoplastic tissues. Angiogenesis, the development of new blood vessels from preexisting capillary networks, plays an important role in a number of physiologic and pathologic processes, including reproduction, wound repair, inflammatory diseases, and tumor growth. Angiogenesis involves sequential steps that are triggered in response to angiogenic growth factors released by inflammatory, mesenchymal, or tumor cells that act as ligands for endothelial cell receptor tyrosine kinases. Stimulated endothelial cells detach from neighboring cells and migrate, proliferate, and form tubes. The immature tubes are subsequently invested and stabilized by pericytes or smooth muscle cells. Angiogenesis depends upon complex interactions among various classes of molecules, including adhesion molecules, proteases, structural proteins, cell surface receptors, and growth factors. The therapeutic manipulation of angiogenesis targeted against ischemic and neoplastic diseases has been investigated in preclinical animal models and in clinical trials. Proangiogenic trials that have stimulated vessel growth in ischemic coronary or peripheral tissues through expression, delivery, or stimulated release of growth factors have shown efficacy in animal models and mixed results in human clinical trials. Antiangiogenic trials have used strategies to block the function of molecules critical for new vessel growth or maturation in the treatment of a variety of malignancies, mostly with results less encouraging than those seen in preclinical models. Pro-and antiangiogenic clinical trials demonstrate that strategies for optimal drug delivery, dosing schedules, patient selection, and endpoint measurements need further investigation and refinement before the therapeutic manipulation of angiogenesis will realize its full clinical potential.

Abstract
BACKGROUND The vascular endothelial growth factor family has been implicated in tumorigenesis and metastasis. The prognostic value of each vascular endothelial growth factor family member, particular VEGF/ VEGFR co-expression, in patients with non-small lung cancer remains controversial. MATERIALS AND METHODS Relevant literature was identified by searching PubMed, EMBASE and Web of Science. Studies evaluating expression of VEGFs and/or VEGFRs by immunohistochemistry or ELISA in lung cancer tissue were eligible for inclusion. Hazard ratios (HRs) and 95% confidence intervals (CIs) from individual study were pooled by using a fixed- or random-effect model, heterogeneity and publication bias analyses were also performed. RESULTS 74 studies covering 7,631 patients were included in the meta-analysis. Regarding pro-angiogenesis factors, the expression of VEGFA (HR=1.633, 95%CI: 1.490-1.791) and VEGFR1 (HR=1.924, 95%CI: 1.220-3.034) was associated separately with poor survival. Especially, VEGFA over-expression was an independent prognostic factor in adenocarcinoma (ADC) (HR=1.775, 95%CI: 1.384-2.275) and SCC (HR=2.919, 95%CI: 2.060-4.137). Co-expression of VEGFA/VEGFR2 (HR=2.011, 95%CI: 1.405-2.876) was also significantly associated with worse survival. For lymphangiogenesis factors, the expression of VEGFC (HR=1.611, 95%CI: 1.407-1.844) predicted a poor prognosis. Co-expression of VEGFC/VEGFR3 (HR=2.436, 95%CI: 1.468-4.043) emerged as a preferable prognostic marker. CONCLUSIONS The expression of VEGFA (particularly in SCC and early stage NSCLC), VEGFC, VEGFR1 indicates separately an unfavorable prognosis in patients with NSCLC. Co-expression VEGFA/ VEGFR2 is comparable with VEGFC/VEGFR3, both featuring sufficient discrimination value as preferable as prognostic biologic markers.

Abstract
Background Basic fibroblast growth factor (bFGF) is known to stimulate angiogenesis and thus to influence the proliferation, migration and survival of tumor cells. Many studies examined the relationship between human bFGF overexpression and survival in lung cancer patients, but the results have been mixed. To systematically summarize the clinical prognostic function of bFGF in lung cancer, we performed this systematic review with meta-analysis. Method Studies were identified by an electronic search of PubMed, EMBASE, China National Knowledge Infrastructure and Wanfang databases, including publications prior toAugust 2014. Pooled hazard ratios (HR) for overall survival (OS) were aggregated and quantitatively analyzed by meta-analysis. Results Twenty-two studies (n = 2154) were evaluated in the meta-analysis. Combined HR suggested that bFGF overexpression had an adverse impact on survival of patients with lung cancer(HR = 1.202,95%CI, 1.022–1.382). Our subgroup analysis revealed that the combined HR evaluating bFGF expression on OS in operable non-small cell lung cancer (NSCLC) was 1.553 (95%CI, 1.120–1.986); the combined HR in small cell lung cancer (SCLC) was 1.667 (95%CI, 1.035–2.299). There was no significant impact of bFGF expression on survival in advanced NSCLC. Conclusion This meta-analysis showed that bFGF overexpression is a potential indicator of worse prognosis for patients with operable NSCLC and SCLC, but is not associated with outcome in advanced NSCLC. The data suggests that high bFGF expression is highly related to poor prognosis. Nevertheless,more high-quality studies should be performed in order to provide additional evidence for the prognostic value of bFGF in lung cancer.

Abstract
JWH-015, a cannabinoid receptor 2 (CB2) agonist has tumor regressive property in various cancer types. However, the underlying mechanism by which it acts in lung cancer is still unknown. Tumor associated macrophage (TAM) intensity has positive correlation with tumor progression. Also, macrophages recruited at the tumor site promote tumor growth by enhancing epithelial to mesenchymal (EMT) progression. In this study, we analyzed the role of JWH-015 on EMT and macrophage infiltration by regulation of EGFR signaling. JWH-015 inhibited EMT in NSCLC cells A549 and also reversed the mesenchymal nature of CALU-1 cells by downregulation of EGFR signaling targets like ERK and STAT3. Also, in vitro co-culture experiments of A549 with M2 polarized macrophages provided evidence that JWH-015 decreased migratory and invasive abilities which was proved by reduced expression of FAK, VCAM1, and MMP2. Furthermore, it decreased macrophage induced EMT in A549 by attenuating the mesenchymal character by downregulating EGFR and its targets. These results were confirmed in an in vivo subcutaneous syngenic mouse model where JWH-015 blocks tumor growth and also inhibits macrophage recruitment and EMT at the tumor site which was regulated by EGFR pathway. Finally, JWH-015 reduced lung tumor lesions in an in vivo tumorigenicity mouse model. These data confer the impact of this cannabinoid on anti-proliferative and anti-tumorigenic effects, thus enhancing our understanding of its therapeutic efficacy in NSCLC. Our findings open new avenues for cannabinoid receptor CB2 agonist-JWH-015 as a novel and potential therapeutic target based on EGFR downregulation mechanisms in NSCLC. © 2016 Wiley Periodicals, Inc.

Abstract
AIM Non-small cell lung carcinoma is the leading cause of cancer related to death in the world. Squamous cell lung carcinoma (SqCLC) is the second most frequent histological subtype of lung carcinomas. Recently, growth factors, growth factor receptors, and signal transduction system-related gene amplifications and mutations are extensively under investigation to estimate the prognosis and to develop individualized therapies in SqCLC. In this study, besides the signal transduction molecule phosphatidyl inositol-3-phosphate kinase (IP3K) p110α, we explored the expressions of fibroblast growth factor 2 (FGF2) and receptor-1 (FGFR1) in tumor tissue and also their clinical and prognostic significance in patients with early/advanced SqCLC. MATERIALS AND METHODS From 2005 to 2013, 129 patients (23 early, 106 advanced disease) with a histopathological SqCLC diagnosis were selected from the hospital files of Cukurova University Medical Faculty for this study. Two independent pathologists evaluated FGFR1, FGF2, and PI3K (p110α) expressions in both tumor and stromal tissues from 99 of the patients with sufficient tissue samples, using immunohistochemistry. Considering survival analysis separately for patients with both early and advanced stage diseases, the relationship between the clinical features of the patients and expressions were evaluated by univariate and multivariate analyses. RESULTS FGFR1 expression was found to be low in 59 (60%) patients and high in 40 (40%) patients. For FGF2; 12 (12%) patients had high, 87 (88%) patients had low expression and for IP3K; 31 (32%) patients had high and 66 (68%) patients had low expressions. In univariate analysis, overall survival (OS) was significantly associated with stage of the disease and the performance status of the patient (P<0.0001 and P<0.001). There was no significant difference in OS of the patients with either low or high expressions of FGFR1, FGF2, and IP3K. When the patients with early or advanced stage disease were separately taken into consideration, the relationship did not differ, either. Any of FGFR1, FGF2 or IP3K expressions was not found predictive for the treatment of early or advanced staged patients. On the other hand, the expressions of both FGFR1 and FGF2 were significantly different with respect to smoking, scar of tuberculosis and scar of radiotherapy (P=0.002; P=0.06 and P=0.05, respectively). DISCUSSION There has not been identified an effective individualized treatment for SqCLC yet. Therefore, in order to be able to develop such a treatment in the future, it is essential to identify the genetic abnormalities that are responsible for the biological behaviors and carcinogenesis of SqCLC. Although we could not show the prognostic and predictive significance of FGFR1, FGF2 and IP3K expressions in SqCLC, we determined the expression rates of FGFR1, FGF2 and IP3K as a reference for Turkish patients. In conclusion, we want to put some emphasis on the fact that, pulmonary fibrosis which is a late complication of radiotherapy at stage III disease, and the scar of tuberculosis could be associated with FGFR1 and FGF2 expressions.

Abstract
To date therapeutic options for squamous cell lung cancer patients remain scarce because no druggable targets have been identified so far. Aberrant signaling by FGFs (fibroblast growth factors) and FGFRs (fibroblast growth factors receptors) has been implicated in several human cancers and, particularly, in squamous non-small cell lung cancer (NSCLC). FGFR gene amplifications, somatic missense mutations, chromosomal translocations are the most frequent mechanisms able to induce aberrant activation of this pathway. Data from literature have established that the presence of an aberrant FGFR signaling has to be considered a possible negative prognostic factor but predictive of potential sensitivity to FGFR inhibitors. In the last years, clinical research efforts allowed to identify and evaluate promising FGFR inhibitors, such as monoclonal antibodies, ligand traps, non-selective or selective tyrosine kinase inhibitors. This review summarizes the current knowledge about FGFR alterations in NSCLC and the relative inhibitors in development, in particular in squamous NSCLC.

Abstract
The endocannabinoid anandamide (AEA), a neurotransmitter was shown to have anti-cancer effects. Fatty acid amide hydrolase (FAAH) metabolizes AEA and decreases its anti-tumorigenic activity. In this study, we have analyzed the role of FAAH inhibition in non-small cell lung cancer (NSCLC). We have shown that FAAH and CB1 receptor which is activated by AEA are expressed in lung adenocarcinoma patient samples and NSCLC cell lines A549 and H460. Since the synthetic analogue of anandamide (Met-F-AEA) did not possess significant anti-tumorigenic effects, we used Met-F-AEA in combination with FAAH inhibitor URB597 which significantly reduced EGF (epidermal growth factor)-induced proliferative and chemotactic activities in vitro when compared to anti-tumorigenic activity of Met-F-AEA alone. Further analysis of signaling mechanisms revealed that Met-F-AEA in combination with URB597 inhibits activation of EGFR and its downstream signaling ERK, AKT and NF-kB. In addition, it inhibited MMP2 secretion and stress fiber formation. We have also shown that the Met-F-AEA in combination with URB597 induces G0/G1 cell cycle arrest by downregulating cyclin D1 and CDK4 expressions, ultimately leading to apoptosis via activation of caspase-9 and PARP. Furthermore, the combination treatment inhibited tumor growth in a xenograft nude mouse model system. Tumors derived from Met-F-AEA and URB597 combination treated mice showed reduced EGFR, AKT and ERK activation and MMP2/MMP9 expressions when compared to Met-F-AEA or URB597 alone. Taken together, these data suggest in EGFR overexpressing NSCLC that the combination of Met-F-AEA with FAAH inhibitor resulted in superior therapeutic response compared to individual compound activity alone.

Abstract
Cytotoxic effects of protocatechuic acid (PCA) upon 3 nonsmall cell lung cancer (NSCLC) cell lines, A549, H3255, and Calu-6 cell lines, were examined. PCA at 1, 2, 4, and 8 μM was used to treat these cells. Results showed that PCA dose-dependently reduced cell growth; and at 2-8 μM enhanced protein expression of Bax and cleaved caspase-3; as well as diminished Bcl-2 expression. This compound destabilized mitochondrial membrane via increasing caspase-3 activity, decreasing mitochondrial membrane potential and Na(+)-K(+)-ATPase activity in these cells. PCA treatments dose-dependently decreased protein expression of vascular endothelial growth factor and fibronectin, as well as lowered interleukin (IL)-6 and IL-8 release; and at 2-8 μM suppressed protein expression of basic fibroblast growth factor, matrix metalloproteinase (MMP)-2 and MMP-9. Furthermore, PCA treatments dose-dependently downregulated nuclear factor kappa (NF-κ)B p50 and NF-κB p65 protein expression, and at 2-8 μM suppressed protein expression of p-p38, p-JNK, and p-focal adhesion kinase (FAK). Our data revealed that PCA declined FAK, mitogen-activated protein kinase, and NF-κB activation, which subsequently decreased the production of cytokines and growth factors, and consequently inhibited proliferation of 3 test NSCLC cells. These findings suggest that PCA could provide wide-ranging anti-NSCLC potency.

Abstract
With the introduction of targeted agents primarily applicable to non-small cell lung cancer (NSCLC) of adenocarcinoma histology, there is a heightened unmet need in the squamous cell carcinoma population. Targeting the angiogenic fibroblast growth factor (FGF)/FGF receptor (FGFR) signaling pathway is among the strategies being explored in squamous NSCLC; these efforts are supported by growth-promoting effects of FGF signaling in preclinical studies (including interactions with other pathways) and observations suggesting that FGF/FGFR-related aberrations may be more common in squamous versus adenocarcinoma and other histologies. A number of different anti-FGF/FGFR approaches have shown promise in preclinical studies. Clinical trials of two multitargeted tyrosine kinase inhibitors are restricting enrollment to patients with squamous NSCLC: a phase I/II trial of nintedanib added to first-line gemcitabine/cisplatin and a phase II trial of ponatinib for previously treated advanced disease, with the latter requiring not only squamous disease but also a confirmed FGFR kinase amplification or mutation. There are several ongoing clinical trials of multitargeted agents in general NSCLC populations, including but not limited to patients with squamous disease. Other FGF/FGFR-targeted agents are in earlier clinical development. While results are awaited from these clinical investigations in squamous NSCLC and other disease settings, additional research is needed to elucidate the role of FGF/FGFR signaling in the biology of NSCLC of different histologies.

Abstract
Protein expression of vascular endothelial growth factor A (VEGF-A) and matrix metalloproteinase 9 (MMP-9) was studied in gastric carcinoma patients in relation to clinicopathological characteristics and prognosis. Fifty-four samples of gastric carcinoma tissue and 15 samples of adjacent normal gastric mucosal tissue were examined immunohistochemically. Expression rates of VEGF-A (66.7%) and MMP-9 (63.0%) in carcinoma tissue were significantly higher than in normal tissue (6.7% for both proteins). VEGF-A and MMP9 expression was associated with tumour size, invasion depth, lymph node metastasis, degree of histological differentiation and pathological stage, but not age or sex. VEGF-A expression was positively correlated with that of MMP-9. Expression of VEGF-A and MMP-9 were each inversely correlated with 5-year survival. VEGF-A and MMP-9 were overexpressed in tumours compared with normal tissue; they may act together to increase carcinogenesis and the progression, invasion and metastasis of gastric carcinoma, and could be used as biomarkers for the prognosis of gastric carcinoma.

Abstract
Despite major advances in cancer therapeutics, the prognosis for lung cancer patients is still poor and the median survival for patients presenting with advanced non-small cell lung cancer (NSCLC) is only 8-10 months. Angiogenesis is an important biological process and a relatively early event during lung cancer pathogenesis. Anti-angiogenic agents are used in treating patients with NSCLC, and their molecular biomarkers are also being assessed to predict response. A better understanding of the biology of angiogenesis in NSCLC may reveal new targets for treating this malignancy. In this article, we review the expression and prognostic impact of the angiogenic growth factors, vascular endothelial growth factor and basic fibroblast growth factor, in NSCLC.

Abstract
BACKGROUND The role of matrix metalloproteinase 9 (MMP-9) expression in non-small cell lung cancer (NSCLC) remains controversial. We performed a systematic review of the literature with meta-analysis. METHODS Electronic databases were used to identify published studies before December 1, 2011. Pooled hazard ratio (HR) with 95% confidence interval (95% CI) was used to estimate the strength of the association between MMP-9 expression survival of NSCLC patients. Heterogeneity and publication bias were also assessed. RESULTS The final analysis of 2029 NSCLC cases from 17 studies is presented. The combined HR of 1.84 (95% CI: 1.62-2.09) suggested that MMP-9 over-expression had a poor prognosis in patients with NSCLC. Subgroup analyses also detected significant association. Heterogeneity and publication bias was absent in current meta-analysis. Sensitivity analyses suggested that the summary statistics obtained should approximate the actual average. CONCLUSION High MMP-9 expression is associated with a poor prognosis in patients with NSCLC.

Abstract
Despite recent progress in the treatment on non-small cell lung cancer (NSCLC), outcomes remain suboptimal. Treatment advances that target the epidermal growth factor receptor (EGFR) and vascular endothelial growth factor (VEGF) signaling pathways highlight the need to understand the multiple convergent growth factor signaling pathways involved in the pathogenesis of NSCLC. Signaling through fibroblast growth factors (FGF), long recognized for its pro-angiogenic activity, has recently emerged as a contributing factor in the pathogenesis and progression of NSCLC through an autocrine signaling loop. In addition, this pathway may function as a mechanism of resistance to anti-EGFR and anti-VEGF treatment. Clinical experience with FGF receptor (FGFR) inhibitors is mounting, and more specific inhibitors of this signaling pathway are in development. This review describes the structure of the FGF signaling pathway, delineates its dual roles in angiogenesis and proliferation in NSCLC, evaluates FGF ligand and receptor expression as prognostic biomarkers in NSCLC, and discusses the development of FGF pathway inhibitors for the treatment of lung malignancies.

Abstract
BACKGROUND The purpose of the present study was to assess the value of matrix metalloproteinase (MMP)-2 and MMP-9 expression and other potential prognostic factors in predicting the clinical outcome of patients after definitive surgery for pathologic stage IA non-small cell lung cancer (NSCLC). METHODS One hundred and forty-six consecutive and non-selected patients who underwent definitive surgery for stage IA NSCLC were included in this study. Formalin-fixed paraffin-embedded specimens were stained for MMP-2 and MMP-9, which were statistically evaluated for their prognostic value and other clinicopathological parameters. RESULTS Of the 146 patients studied, 102 (69.9%) cases were classified as having high expression for MMP-2. A total of 89 carcinomas (61.0%) had high expression for MMP-9. MMP-9 expression correlated with Eastern Cooperative Oncology Group (ECOG) performance status, pT stage, and differentiation (P = 0.005, <0.001, and <0.001, respectively). Vessel invasion, pT stage, and MMP-9 expression maintained their independent prognostic influence on overall survival (P = 0.037, <0.001, and <0.001, respectively). CONCLUSIONS From results of our relatively large database, MMP-9 may be considered as a viable biomarker that can be used in conjunction with other prognostic factors such as vessel invasion and pT stage to predict the prognosis of patients with completely resected pathologic stage IA NSCLC.

Abstract
Maintenance of both normal epithelial tissues and their malignant counterparts is supported by the host tissue stroma. The tumor stroma mainly consists of the basement membrane, fibroblasts, extracellular matrix, immune cells, and vasculature. Although most host cells in the stroma possess certain tumor-suppressing abilities, the stroma will change during malignancy and eventually promote growth, invasion, and metastasis. Stromal changes at the invasion front include the appearance of carcinoma-associated fibroblasts (CAFs). CAFs constitute a major portion of the reactive tumor stroma and play a crucial role in tumor progression. The main precursors of CAFs are normal fibroblasts, and the transdifferentiation of fibroblasts to CAFs is driven to a great extent by cancer-derived cytokines such as transforming growth factor-β. During recent years, the crosstalk between the cancer cells and the tumor stroma, highly responsible for the progression of tumors and their metastasis, has been increasingly unveiled. A better understanding of the host stroma contribution to cancer progression will increase our knowledge about the growth promoting signaling pathways and hopefully lead to novel therapeutic interventions targeting the tumor stroma. This review reports novel data on the essential crosstalk between cancer cells and cells of the tumor stroma, with an emphasis on the role played by CAFs. Furthermore, it presents recent literature on relevant tumor stroma- and CAF-related research in non-small cell lung cancer.

Abstract
PURPOSE The prognostic value of the tumor cell expression of the fibroblast growth factor 2 (FGF-2) in patients with non-small-cell lung cancer (NSCLC) is unclear. The present study investigated the effect of tumor cell expression of FGF-2 on the outcome of 60 patients irradiated for Stage II-III NSCLC. METHODS AND MATERIALS The effect of FGF-2 expression and 13 additional factors on locoregional control (LRC), metastasis-free survival (MFS), and overall survival (OS) were retrospectively evaluated. These additional factors included age, gender, Karnofsky performance status, histologic type, histologic grade, T and N category, American Joint Committee on Cancer stage, surgery, chemotherapy, pack-years, smoking during radiotherapy, and hemoglobin during radiotherapy. Locoregional failure was identified by endoscopy or computed tomography. Univariate analyses were performed with the Kaplan-Meier method and the Wilcoxon test and multivariate analyses with the Cox proportional hazard model. RESULTS On univariate analysis, improved LRC was associated with surgery (p = .017), greater hemoglobin levels (p = .036), and FGF-2 negativity (p <.001). On multivariate analysis of LRC, surgery (relative risk [RR], 2.44; p = .037), and FGF-2 expression (RR, 5.06; p <.001) maintained significance. On univariate analysis, improved MFS was associated with squamous cell carcinoma (p = .020), greater hemoglobin levels (p = .007), and FGF-2 negativity (p = .001). On multivariate analysis of MFS, the hemoglobin levels (RR, 2.65; p = .019) and FGF-2 expression (RR, 3.05; p = .004) were significant. On univariate analysis, improved OS was associated with a lower N category (p = .048), greater hemoglobin levels (p <.001), and FGF-2 negativity (p <.001). On multivariate analysis of OS, greater hemoglobin levels (RR, 4.62; p = .002) and FGF-2 expression (RR, 3.25; p = .002) maintained significance. CONCLUSIONS Tumor cell expression of FGF-2 appeared to be an independent negative predictor of LRC, MFS, and OS.

Abstract
To evaluate the prognostic value of matrix metalloproteinase2 (MMP-2) expression in patients with non-small cell lung cancer (NSCLC), the electronic database PubMed, EMBASE were searched for relevant articles. The meta-analysis was finally based on 11 studies that included 1,439 patients, and combined HR was 1.66 (95% confidence intervals (CI: 1.37-2.01). Its effect also appeared significant when the analysis was restricted to tumor cell expression and patients with adenocarcinoma (HR 2.08 (95% CI: 1.24-3.48)). This study supported the fact that MMP-2 could be included in further prospective trials studying prognostic factors in NSCLC.

Abstract
The DNA enzyme Dz13, targeted against the oncogene c-Jun, is capable of inhibiting various model tumours in mice albeit in ectopic models of neoplasia. In previous studies using orthotopic models of disease, the inhibitory effects of Dz13 on secondary growth was a direct result of growth inhibition at the primary lesion site. Thus, the direct and genuine effects on metastasis were not gauged. In this study, Dz13 was able to inhibit both locoregional and distal metastasis of tumour cells in mice, in studies where the primary tumours were unaffected due to the late and clinically-mimicking nature of treatment commencement. In addition, the effect of Dz13 against tumours has now been extended to encompass breast and prostate cancer. Dz13 upregulated the matrix metalloproteinase (MMP)-2 and MMP-9, and decreased expression of MT1-MMP (MMP-14) in cultured tumour cells. However, in sections of ectopic tumours treated with Dz13, both MMP-2 and MMP-9 were downregulated. Thus, not only is Dz13 able to inhibit tumour growth at the primary site, but also able to decrease the ability of neoplastic cells to metastasise. These findings further highlight the growing potential of Dz13 as an antineoplastic agent.

Abstract
A variety of susceptibility genes have been associated with cancer but definitive conclusions have been difficult to draw partly hampered by the small number of subjects in each study. We undertook a comprehensive genetic meta-analysis of all matrix metalloproteinase (MMP) genes investigated using an allelic-association case-control model in the 3 major cancers of lung, breast and colorectal cancer. Electronic databases were searched until and including July 2008 for any MMP genetic association study in lung, breast and colorectal cancer. Odds ratio (OR) and 95% confidence intervals (CI) were determined for each gene disease association using fixed and random effect models. Twenty-five studies addressing 5 polymorphisms in 4 genes were analyzed among 30,651 individuals (15,328 cases and 15,253 controls). The MMP-1 nt-1607 polymorphism was significantly associated with colorectal cancer in both the dominant (OR, 1.66; 95% CI, 1.14-2.42; p = 0.008) and recessive (OR, 1.59; 95% CI, 1.15-2.20; p = 0.005) models. MMP-2(1306C-->T) (OR, 0.53; 95% CI, 0.40-0.72; p < 0.0001) and 735(C-->T) (OR, 0.65; 95% CI, 0.53-0.79; p < 0.0001) were significantly associated with protection against lung cancer. No association was found with the MMP 1, 2, 3 or 9 polymorphisms with breast cancer, MMP-1, 3 or 9 with lung cancer or MMP-2, 3 or 9 with colorectal cancer. There may be a genetic influence in the development of colorectal and lung cancer. Subjects with the MMP-1 nt-1607 polymorphism have an increased association with colorectal cancer. Those homozygous for either the MMP-2/1306T or 735T allele may be at reduced risk of lung cancer, although the evidence base is small.

Abstract
PURPOSE Fibroblast growth factor 2 (FGF2; basic fibroblast growth factor, b-FGF) and its main receptor FGFR-1 are important in both hemangiogenesis and lymphangiogenesis. Murine studies have indicated a close interplay between both FGF2 and platelet-derived growth factor-B (PDGF-B) as well as FGF2 and vascular endothelial growth factor-3 (VEGFR-3). This study investigates the prognostic impact of FGF2 and FGFR-1 in tumor cells and tumor stroma of resected non-small cell lung carcinomas (NSCLC) and explores the importance of their coexpression with VEGFR-3 or PDGF-B. METHODS Tumor tissue samples from 335 resected patients with stage I to IIIA NSCLC were obtained and tissue microarrays were constructed from duplicate cores of tumor cells and tumor-related stroma from each specimen. Immunohistochemistry was used to evaluate the expression of the molecular markers FGF2, FGFR-1, VEGFR-3, and PDGF-B. RESULTS In univariate analyses, high tumor cell FGF2 expression (p = 0.015) was a negative prognostic indicator for disease-specific survival. In tumor stroma, high FGF2 (p = 0.024) expression correlated with good prognosis. In multivariate analyses, high expression of FGF2 in tumor cells (p = 0.038) was an independent negative prognostic factor whereas increased FGF2 in stroma (p = 0.015) was a positive prognosticator. Tumor cell coexpressions of FGF2/VEGFR-3 (p < 0.001) and FGFR-1/PDGF-B (p = 0.002) were significant indicators of poor prognosis. CONCLUSIONS Expression of FGF2 in tumor cells is an independent negative prognostic factor, and the coexpressions of FGF2/VEGFR-3 and FGFR-1/PDGF-B are strongly associated with poor survival in NSCLC patients.

Abstract
INTRODUCTION Protein expressions of angiogenic markers provide prognostic information on patients with non-small cell lung cancer (NSCLC). Both expression and its prognostic impact may be associated with patient selection. Data addressing the prognostic relevance of angiogenic marker expression in NSCLC patients treated with postoperative radiotherapy (PORT) is warranted. METHODS In 55 patients with stage I-IIIA NSCLC administered PORT between 1990 and 2005, we have reviewed the clinicopathological variables and investigated the expression of angiogenic markers in tumor and stroma in tissue micro arrays. RESULTS The median follow-up was 114 months and the major end point disease-specific survival (DSS). Univariate analysis showed that high expression of vascular endothelial growth factor A (VEGF-A) (p = 0.004), VEGF receptor-1 (VEGFR-1, p = 0.028), VEGFR-2 (p = 0.021), VEGFR-3 (p = 0.001) and platelet derived growth factor (PDGF) in tumors correlated significantly with a poor survival. Inversely, high basic fibroblast growth factor (bFGF) expression in stroma was associated with significantly improved DSS (p = 0.017). In multivariate analyses, tumor PDGF expression appeared independently associated with a shorter DSS (hazard ratio 5.42, p = 0.002) and stromal bFGF expression an increased DSS (hazard ratio 0.077, p < 0.001). CONCLUSIONS Tumor PDGF expression was an independent negative prognostic factor and stromal bFGF expression an independent positive prognostic factor for survival in NSCLC receiving PORT.

Abstract
Matrix metalloproteinases (MMPs) play a crucial role in cancer progression and their over-expression is often associated with unfavorable survival of non-small cell lung cancer (NSCLC). Because genetic variants can alter expression level or biological activity of MMPs, we hypothesized that potentially functional single nucleotide polymorphisms (SNPs) in key MMP genes may be associated with the survival of NSCLC patients. We selected and genotyped 14 putative functional SNPs in six MMP genes (MMP1, MMP2, MMP3, MMP7, MMP9 and MMP12) using PCR-RFLP methods in 561 NSCLC patients. Kaplan-Meier method with the log-rank test and Cox proportional hazard models were used for the survival analyses. The C-1562T, Arg279Gln and Arg668Gln polymorphisms in MMP9 were significantly associated with survival of patients with NSCLC (log-rank p values = 0.032, 0.038 and 0.036, respectively). The C-1562T and Arg668Gln loci were in complete linkage disequilibrium (r(2) = 1). Patients carrying the 668Gln allele had improved survival with a median survival time (MST) of 51.6 months, compared with 21.8 months for those with the 668Arg/Arg genotype (log-rank p = 0.010). In contrast, the 279Gln/Gln genotype was associated with a significantly shortened MST (17.3 months, log-rank p = 0.030) in the recessive model. In the final multivariate Cox regression model, 279Gln/Gln was identified as an independent prognostic factor with an adjusted hazard ratio of 1.60 (95% confidence interval 1.07-2.41). The MMP9 Arg279Gln and Arg668Gln SNPs are potential predictors of survival in NSCLC patients.

Abstract
PURPOSE To identify the patterns of protein expression of basic fibroblast growth factor (bFGF) and FGF receptors 1 and 2 in non-small cell lung carcinoma (NSCLC) and their role in the early pathogenesis of squamous cell carcinoma (SCC) of the lung. EXPERIMENTAL DESIGN Archived tissue from NSCLC (adenocarcinoma and SCC; n = 321) and adjacent bronchial epithelial specimens (n = 426) were analyzed for the immunohistochemical expression of bFGF, FGFR1, and FGFR2, and the findings were correlated with clinicopathologic features of the patients. RESULTS High expression of bFGF, FGFR1, and FGFR2 was shown in most NSCLC tumors. The pattern of expression for all markers varied according to tumor histologic type and cellular localization. Cytoplasmic expression scores were significantly higher in tumors than in normal epithelia. Nuclear bFGF (P = 0.03) and FGFR1 (P = 0.02) levels were significantly higher in women than in men. Although cytoplasmic FGFR1 expression was significantly higher (P = 0.002) in ever smokers than in never smokers, nuclear FGFR1 (P = 0.0001) and FGFR2 (P = 0.003) expression was significantly higher in never smokers. Different prognostic patterns for the expression of these markers were detected for both NSCLC histologic types. Dysplastic changes showed significantly higher expression of all markers compared with squamous metaplasia. CONCLUSIONS bFGF, FGFR1, and FGFR2 are frequently overexpressed in SCC and adenocarcinoma of the lung. bFGF signaling pathway activation may be an early phenomenon in the pathogenesis of SCC and thus an attractive novel target for lung cancer chemopreventive and therapeutic strategies.

Abstract
BACKGROUND AND OBJECTIVE Matrix metalloproteinases (MMPs) play an important role in several steps of cancer development. MMP2 and MMP9 have previously been implicated in lymphatic and vascular invasion of lung cancer; however, the expression and prognostic significance of MMP2 and MMP9 is not fully clarified. This study was designed to investigate the significance of MMP2 and MMP9 in lung cancer tissue or serum, and their correlation with lung cancer prognosis. METHODS Immunohistochemical analysis was performed to determine MMP2 and MMP9 staining in human nonsmall cell lung cancer (NSCLC). Serum MMP2 and MMP9 protein levels in patients after surgery were measured using the ELISA method. The correlation between MMP2 and MMP9 serum levels and clinicopathological features of NSCLC were analyzed by survival analysis. We also performed reverse transcriptase (RT)-PCR assays to detect messenger RNA (mRNA) expression to further confirm the activity of MMP2 and MMP9 in human lung cancer. RESULTS Increased MMP2 immunostaining and MMP2 serum level correlated with advanced tumor stage and the presence of distant metastasis (Pearson's chi(2) test and ANOVA, p < 0.05). However, for MMP9, only serum level showed a correlation with advanced tumor stage. No significant correlation was observed between MMP2 or MMP9 immunostaining expression and tumor histologic features (Pearson's chi(2) test, p = 0.061 and p = 0.087, respectively). A high densitometry value of MMP2 and MMP9 PCR products (i.e. mRNA expression level) was related to poor differentiation grade, distant metastasis, and small cell carcinoma histologic type (ANOVA, p < 0.05). CONCLUSIONS Our results suggest that MMP2 is a more sensitive predictor than MMP9 of lung cancer progression, metastasis, and survival. Serum MMP2 levels may be a valuable prognosis variable and could help to stratify lung cancer patients into low- and high-risk groups.

Abstract
Over 95% of patients with small-cell lung cancer (SCLC) die within five years of diagnosis. The standard of care and the dismal prognosis for this disease have not changed significantly over the past 25 years. Some of the characteristics of SCLC that have defined it as a particularly virulent form of cancer -- rapid proliferation, excessive metabolic and angiogenic dependence, apoptotic imbalance and genetic instability -- are now being pursued as tumor-specific targets for intervention both in preclinical and early phase clinical studies. Here, we summarize areas of ongoing anti-cancer drug development, including classes of agents that target essential pathways regulating proliferation, angiogenesis, apoptotic resistance, chromosomal and protein stability, and cell-cell and cell-matrix interaction.

Abstract
BACKGROUND Platelet derived growth factor (PDGF) and PDGFR-beta are expressed and have been found to have prognostic value in several human cancers. Data in non-small-cell cancer cell lines have suggested that PDGFR is a therapeutic target for drug development. In the current study PDGFR-beta expression and prognostic value in small cell lung cancer (SCLC) was investigated. METHODS AND MATERIALS Paraffin-embedded tissue blocks from 53 patients with limited and extensive stage SCLC were obtained for immunohistochemical staining. Tumors from each patient were sampled 3 times and stained with PDGFR-beta specific antibody. Patients were divided into low and high staining groups based on intensity. RESULTS There was high intensity PDGFR-beta staining in 20 patients with SCLC. Another 29 expressed low intensity PDGFR-beta staining, with only 4 patients showing no PDGFR-beta staining. There was no statistically significant difference in 5 year overall survival between patients with low levels of PDGFR-beta staining vs. those with high level staining SCLC tumors (p = 0.538). CONCLUSIONS The present study found that the majority of SCLC patients express, at least, a low level of PDGF-beta. However, the level of PDGFR-beta expression was not a statistically significant predictor of 5 year overall survival in SCLC.

Abstract
BACKGROUND Patients diagnosed with locally advanced rectal cancer usually receive surgical resection and adjuvant chemoradiation therapy. Lymph node involvement is an important clinical prognostic factor affecting recurrence and survival. Few studies have explored molecular markers associated with lymph node involvement of rectal cancer. PATIENTS AND METHODS Tissue was obtained from 59 patients with locally advanced rectal cancer who were treated with adjuvant chemoradiation therapy. We assessed messenger RNA (mRNA) levels of genes involved in pathways of angiogenesis (vascular endothelial growth factor [VEGF], cyclooxygenase-2), apoptosis (survivin), tumor growth and epidermal growth factor receptor (EGFR), DNA repair (ERCC1, Rad51), and the DNA synthesis in tumor tissue and tumor-adjacent normal tissue from paraffin-embedded samples using laser-capture microdissection methods. RESULTS Twenty-four patients had no involvement of regional lymph nodes and 35 had lymph node metastases. In univariate analysis, patients with lymph node involvement had higher mRNA levels of VEGF and survivin in tumor tissue and EGFR in tumor-adjacent normal tissue compared with patients with no lymph node involvement (P < 0.1; t test). Multivariate analysis using recursive partitioning showed that mRNA levels of EGFR, survivin, and Rad51 are primarily responsible for delineating node positive from node negative. CONCLUSION Gene expression of VEGF, survivin, and EGFR could be associated with lymph node involvement in patients with locally advanced rectal cancer. Further independent studies of those gene expression levels and lymph node involvement are warranted to better characterize the associations.

Abstract
FGF-2, a potent angiogenic factor that is involved in tumor invasion, is known to be released extracellularly by a nonclassical secretory pathway. Recently it has become clear that Epstein-Barr virus, specifically its oncoprotein LMP1, can induce expression of angiogenic factors. Among these factors is FGF-2. LMP1 not only promotes expression of FGF-2, but also the release extracellularly of its 18-kDa isoform. We analyzed the mechanism of FGF-2 release induced by LMP1. Confocal immunofluorescence microscopy revealed colocalization of FGF-2 with LMP1 in small dots also stained positively for CD63 and cathepsin D, markers of late endosomes or multivesicular bodies. Biochemical analysis and immunoelectron microscopy of purified exosomal fractions from cotransfected cells demonstrated increased release of exosomes and the concentration of LMP1 and FGF-2 in these structures. Moreover, cotransfection appeared to induce partial redistribution of the Na(+)/K(+)-ATPase, which participates in FGF-2 release, from the plasma membrane to the intracellular LMP1/FGF-2 positive dots. Treatment with ouabain, which inhibits Na(+)/K(+)-ATPase activity, partially suppressed FGF-2 secretion via exosomes in a dose-dependent manner. The results suggest that exosomes may represent a previously unrecognized mechanism for FGF-2 release mediated by LMP1, and that this pathway involves the activity of Na(+)/K(+)-ATPase.

Abstract
Characteristics of the tumour that affect and predict the survival outcome of patients with cancer are prognostic markers for cancer. In non-small cell lung carcinoma (NSCLC), stage is the main determinant of prognosis and the basis for deciding options for treatment. Patients with early-stage tumour are treated by complete surgical resection, which is curative in 40-70% of patients. That there are other factors important in determining the biology of these tumours, especially genes that have a role in metastasis, is indicated. Such factors could potentially be used to further classify patients into groups according to substages that may be treated differently. During the past decade, a large number of proteins that are putatively important in carcinogenesis and cancer biology have been studied for their prognostic value in NSCLC, but none of them have been proved to be sufficiently useful in clinical diagnosis. Several markers (epidermal growth factor receptor, human epidermal growth factor receptor 2, Ki-67, p53 and Bcl-2) have been studied exhaustively. Ki-67, p53 and Bcl-2 are suggested to be important but weak prognostic markers, by meta-analyses of the results. Cyclin E, vascular endothelial growth factor A, p16(INK4A), p27(kip1) and beta-catenin are promising candidates, but require further study in large randomised clinical trial samples by using standardised assays and scoring systems. Some issues and inconsistencies in the reported studies to date are highlighted and discussed. A guideline for a multi-phase approach for conducting future studies on prognostic immunohistochemistry markers is proposed here.

Abstract
Vascular endothelial growth factor (VEGF) expression is elevated in primary ovarian tumors and metastases. We examined the effect of VEGF on epithelial ovarian cancer (EOC) in vitro invasion and migration and underlying mechanisms. Using the Matrigel invasion assay and colloidal gold phagokinetic track assay, we found that VEGF induced EOC DOV13 invasion and migration in a matrix metalloproteinase (MMP)-dependent manner. Using Western blotting, we show that VEGF, at 20-80 ng/ml, induced secretion of pro-MMP-7 and pro-MMP-9 and activation of pro-MMP-2 in DOV13 conditioned medium in a concentration-dependent manner. However, gelatinolytic activity and total MMP-7 protein in DOV13 conditioned medium reached the maximum upon VEGF treatment at 20-40 ng/ml and decreased at higher-concentration VEGF treatment (80 ng/ml), as shown by DQ-gelatin degradation assay and ELISA. In addition to the effect on MMP secretion/activation, VEGF stimulated secretion of TIMP-2; and blocking TIMP-2 activity by an anti-TIMP-2 MAb significantly increased VEGF (80 ng/ml)-induced DOV13 invasion (p < 0.05), suggesting that VEGF may regulate MMP-2 activity in DOV13 conditioned medium through TIMP-2. Using real-time PCR, we found that VEGF, at 20 ng/ml, significantly increased the expression of VEGFR-1 and VEGFR-2 by approximately 4-fold and 31-fold, respectively, compared to untreated control (p < 0.05). However, the inducing effect of VEGF on VEGFR-2 expression and the internal expression of VEGF121 in DOV13 cells decreased with increasing of VEGF concentration, suggesting the existence of a negative feedback regulatory mechanism. In summary, our results indicate that VEGF may regulate EOC invasion and migration through VEGFR-mediated secretion and activation of MMPs.

Abstract
In healthy lung, Matrix Metalloproteinases (MMPs) and their physiological inhibitors, tissue inhibitors of matrix metalloproteinases (TIMPs), are produced in the respiratory tract by a panel of different structural cells. These activities are mandatory for many physiological processes including development, wound healing and cell trafficking. Deregulation of proteolytic-antiproteolytic network and inappropriate secretion of various MMPs by stimulated structural or inflammatory cells is thought to take part to pathophysiology of numerous lung diseases including asthma, chronic obstructive pulmonary disease (COPD), lung fibrosis and lung cancer. Cytokines and growth factors are involved in these inflammatory processes and some of those mediators interact directly with MMPs and TIMPs leading either to a regulation of their expression or changes in their biological activities by proteolytic cleavage. In turn, cytokines and growth factors modulate secretion of MMPs establishing a complex network of reciprocal interactions. Every MMP seem to play a rather specific role and some variations of their expression are observed in different lung diseases. The precise role of these enzymes and their inhibitors is now studied in depth as they could represent relevant therapeutic targets for many diseases. Indeed, MMP inhibition can lead either to a decrease of the intensity of a pathological process or, in the contrary for some of them, to an increase of disease severity. In this review, we focus on the role played by MMPs and TIMPs in asthma and we provide an overview of their potential roles in COPD, lung fibrosis and lung cancer, with a special emphasis on loops including MMPs and cytokines and growth factors relevant in these diseases.

Abstract
BACKGROUND Due to a dismal prognosis of advanced lung cancer, novel screening tools and more effective treatments are clearly needed. Lately, an increasing number of tumour-released angiogenic cytokines which affect vessel formation, tumour growth, invasion, and metastasis have been identified. Vascular endothelial growth factors (VEGFs) and basic fibroblast growth factor (bFGF) are among the most important angiogenic factors. Based on available literature, we have explored the mechanisms of angiogenesis and its prognostic significance in non-small cell lung cancer, estimated by microvessel density (MVD) and the presence of VEGF and bFGF in the tumour and blood from NSCLC patients. METHODS Several comprehensive Pubmed searches for the period January 1993 to May 2005 were performed using strategic combinations of the terms non-small cell lung cancer, angiogenesis, vascular endothelial growth factor, basic fibroblast growth factor, tumour expression, microvessel density, circulating, and serum. RESULTS NSCLC neoangiogenesis, as measured by MVD, and tumour expression of VEGF are poor prognostic factors for survival (MVD, HR 1.8-2.0; VEGF, HR 1.5). bFGF tumour expression is also associated with poor survival and more aggressive disease. When evaluating the prognostic impact of elevated VEGF levels in blood, 10 of 16 studies (63%) indicated a negative prognostic impact. Of five studies on the prognostic value of circulating bFGF, three studies reported a negative prognostic impact, while one indicated bFGF as a good prognostic factor and one was inconclusive. CONCLUSION Angiogenic factors are poor prognostic indicators for tumour aggressiveness and survival in NSCLC. Assessments of circulating levels of VEGF and possibly bFGF may be valuable future tools for treatment planning and monitoring of treatment effect and relapse. First, however, these blood tests need to be standardised and validated in large-scale prospective clinical trials.

Abstract
PURPOSE Matrix metalloproteinase 9 (MMP-9) plays critical roles in cancer development and aggression. Nonsynonymous single-nucleotide polymorphisms (SNP) in the functional domain of the MMP-9 gene may influence substrate and inhibitor binding and contribute to cancer predisposition and aggression. PATIENTS AND METHODS To test our hypothesis that common nonsynonymous SNPs, R279Q, P574R, and R668Q, in MMP-9 are associated with lung cancer development and metastasis, we conducted a case-control study of 744 patients with incident lung cancer and 747 cancer-free controls in Southeast China. Multivariate logistic regression analysis was used to calculate adjusted odds ratio (OR) and 95% confidence interval (95% CI). RESULTS We found that compared with the 279QQ genotype, the 279RR genotype was associated with significant elevated risk of lung cancer with metastasis (adjusted OR, 1.79; 95% CI, 1.03-3.08), whereas the 574PR heterozygote and 574PP homozygote had 1.46-fold (95% CI, 0.94-2.26) and 1.69-fold elevated risk (95% CI, 1.10-2.60), respectively, compared with the 574RR genotype. When we examined the combined effect of R279Q and P574R and used the 279R and 574P as the risk alleles, a significantly increased risk of lung cancer was associated with both the genotypes containing "1 to 2 risk alleles" (adjusted OR, 2.16; 95% CI, 1.30-3.59) and containing ">2 risk alleles" (adjusted OR, 2.44; 95% CI, 1.48-4.03), and it was more pronounced in 290 lung cancer cases with metastasis [adjusted OR, 2.30 (95% CI, 1.09-4.85) for the 1 to 2 risk alleles subgroup and adjusted OR, 2.82 (95% CI, 1.35-5.88) for the >2 risk alleles subgroup], compared with those without any risk alleles. However, no overall significant associations were observed between R668Q and lung cancer risk in this study population. CONCLUSION These findings indicate that the potentially functional polymorphisms, MMP-9 P574R and R279Q, may confer the biomarker in the occurrence and metastasis of primary lung cancer. Further functional studies including these two genetic variants are warranted to confirm our findings.

Abstract
Although big mitogen-activated protein kinase 1 (BMK1) has been shown to be critical for embryonic angiogenesis, the role of BMK1 in tumor-associated neovascularization is poorly understood. Exogenous tumors were established in BMK1+/+, BMK1flox/+, or BMK1flox/flox mice carrying the Mx1-Cre transgene. Induced deletion of host BMK1 gene significantly reduced the volumes of B16F10 and LL/2 tumor xenografts in BMK1flox/flox mice by 63% and 72%, respectively. Examining the tumors in these induced BMK1-knockout animals showed a significant decrease in vascular density. Localized reexpression of BMK1 in BMK1-knockout mice by administration of adenovirus encoding BMK1 restored tumor growth and angiogenesis to the levels observed in wild-type mice. These observations were further supported by in vivo Matrigel plug assays in which vascular endothelial growth factor- and basic fibroblast growth factor-induced neovacularization was impaired by removing BMK1. Through screening with the Pepchip microarray, we discovered that in BMK1-knockout endothelial cells, phosphorylation of ribosomal protein S6 (rpS6) at Ser235/236 was mostly abrogated, and this BMK1-dependent phosphorylation required the activity of p90 ribosomal S6 kinase (RSK). Immunofluorescent analysis of tumor vasculature from BMK1-knockout and control animals revealed a strong correlation between the presence of BMK1 and the phosphorylation of rpS6 in tumor-associated endothelial cells of blood vessels. As both RSK and rpS6 are known to be important for cell proliferation and survival, which are critical endothelial cell functions during neovascularization, these findings suggest that the BMK1 pathway is crucial for tumor-associated angiogenesis through its role in the regulation of the RSK-rpS6 signaling module.
