[PMID: 38003461 PMCID: PMC10671607 DOI: 10.3390/ijms242216272] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Revised: 11/09/2023] [Accepted: 11/10/2023] [Indexed: 11/26/2023] Open
Abstract
Inflammation is the host response of immune cells during infection and traumatic tissue injury. An uncontrolled inflammatory response leads to inflammatory cascade, which in turn triggers a variety of diseases threatening human and animal health. The use of existing inflammatory therapeutic drugs is constrained by their high cost and susceptibility to systemic side effects, and therefore new therapeutic candidates for inflammatory diseases need to be urgently developed. Natural products are characterized by wide sources and rich pharmacological activities, which are valuable resources for the development of new drugs. This study aimed to uncover the alleviating effect and potential mechanism of natural product Limonium aureum (LAH) on LPS-induced inflammatory responses in macrophages. The experimental results showed that the optimized conditions for LAH ultrasound-assisted extraction via response surface methodology were an ethanol concentration of 72%, a material-to-solvent ratio of 1:37 g/mL, an extraction temperature of 73 °C, and an extraction power of 70 W, and the average extraction rate of LAH total flavonoids was 0.3776%. Then, data of 1666 components in LAH ethanol extracts were obtained through quasi-targeted metabolomics analysis. The ELISA showed that LAH significantly inhibited the production of pro-inflammatory cytokines while promoting the secretion of anti-inflammatory cytokines. Finally, combined with the results of network pharmacology analysis and protein expression validation of hub genes, it was speculated that LAH may alleviate LPS-induced inflammatory responses of macrophages through the AKT1/RELA/PTGS2 signaling pathway and the MAPK3/JUN signaling pathway. This study preliminarily revealed the anti-inflammatory activity of LAH and the molecular mechanism of its anti-inflammatory action, and provided a theoretical basis for the development of LAH as a new natural anti-inflammatory drug.

Abstract
Endometriosis (EM) is characterized by the existence of endometrial mucosa outside the uterine cavity, which causesinfertility, persistent aches, and a decline in women's quality of life. Both hormone therapies and nonhormone therapies, such as NSAIDs, are ineffective, generic categories of EM drugs. Endometriosis is a benign gynecological condition, yet it shares a number of features with cancer cells, including immune evasion, survival, adhesion, invasion, and angiogenesis. Several endometriosis-related signaling pathways are comprehensively reviewed in this article, including E2, NF-κB, MAPK, ERK, PI3K/Akt/mTOR, YAP, Wnt/β-catenin, Rho/ROCK, TGF-β, VEGF, NO, iron, cytokines and chemokines. To find and develop novel medications for the treatment of EM, it is essential to implicitly determine the molecular pathways that are disordered during EM development. Additionally, research on the shared pathways between EM and tumors can provide hypotheses or suggestions for endometriosis therapeutic targets.

Abstract
The coactivator associated arginine methyltransferase (CARM1) promotes transcription, as its name implies. It does so by modifying histones and chromatin bound proteins. We identified nuclear factor I B (NFIB) as a CARM1 substrate and show that this transcription factor utilizes CARM1 as a coactivator. Biochemical studies reveal that tripartite motif 29 (TRIM29) is an effector molecule for methylated NFIB. Importantly, NFIB harbors both oncogenic and metastatic activities, and is often overexpressed in small cell lung cancer (SCLC). Here, we explore the possibility that CARM1 methylation of NFIB is important for its transforming activity. Using a SCLC mouse model, we show that both CARM1 and the CARM1 methylation site on NFIB are critical for the rapid onset of SCLC. Furthermore, CARM1 and methylated NFIB are responsible for maintaining similar open chromatin states in tumors. Together, these findings suggest that CARM1 might be a therapeutic target for SCLC.

Ginsenoside Rb1 from Panax notoginseng Suppressed TNF-α-Induced Matrix Metalloproteinase-9 via the Suppression of Double-Strand RNA-Dependent Protein Kinase (PKR)/NF-κB Pathway. MOLECULES (BASEL, SWITZERLAND) 2022; 27:molecules27228050. [PMID: 36432152 PMCID: PMC9692425 DOI: 10.3390/molecules27228050] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/25/2022] [Revised: 11/12/2022] [Accepted: 11/16/2022] [Indexed: 11/22/2022]
Abstract
Chronic inflammation is commonly accompanied by the stimulation of matrix metalloproteinases (MMPs) production and the degradation of the extracellular matrix. The overexpression of MMP-9 (Gelatinase B) highly participates in the progression of pathetic cardiac remodeling and liver cancer metastasis. Panax notoginseng (Burkill) F. H. Chen (Sanqi), a widely used traditional Chinese medicinal herb, shows myocardial protective and anti-tumor effects. In this study, we examined the inhibitory effect of different PNG extracts on tumor necrosis factor (TNF)-α-induced MMP-9 expression in cardiac myoblast H9c2 cells. Using a bioassay-guided fractionation scheme, the most active extract was fractionated by silica gel column chromatography and high-performance liquid chromatography until an active compound was obtained. The compound was identified as Ginsenoside Rb1 by nuclear magnetic resonance. Ginsenoside Rb1 inhibited TNF-α-induced MMP-9 production in both H9c2 and liver carcinoma HepG-2 cells. Interestingly, it did not affect the MMP-2 (Gelatinase A) level and the cell proliferation of the two cell lines. The inhibitory effects of Ginsenoside Rb1 may be due to its modulation of double-strand RNA-dependent protein kinase and nuclear factor kappa B signaling pathways. The results reveal the potential use of Ginsenoside Rb1 for the treatment of inflammatory and MMP-9-related cardiac remodeling and metastasis of hepatocellular carcinomas.

Abstract
BACKGROUND Endometriosis (EM) is a benign gynecological disease that shares some characteristics with malignancy, such as proliferation and invasion. So far, the pathogenesis of EM is still unclear. In this study, we investigated whether TRIM65 can play a role in the development of EM. METHODS TRIM65 expression levels in eutopic, ectopic, and normal endometrium were detected by quantitative real-time PCR and Western blot. Cell proliferation and invasion of primary endometrial stromal (EMS) cells were detected by CCK-8 and Transwell analysis. The interaction between TRIM65 and DUSP6 or C-myc was measured by coimmunoprecipitation, ubiquitylation, dual luciferase, and chromatin immunoprecipitation analysis. RESULTS We found that TRIM65 was identified as an up-regulated gene in ectopic endometrial tissues and EMS cells compared with control groups without EM. TRIM65 expression was positively correlated with the levels of p-ERK1/2, C-myc, matrix metalloproteinase-2, and integrin β1 in ectopic endometrial tissues in patients and mice. TRIM65 promoted the cell proliferation and invasion of EMS cells via the ERK1/2/C-myc pathway through ubiquitination of DUSP6. C-myc promoted TRIM65 expression through inducing TRIM65 promoter activity. Additionally, the increased expression of TRIM65, C-myc, matrix metalloproteinase-2, integrin β1, and p-ERK1/2 and the decreased expression of DUSP6 in ectopic endometrial tissues were significantly suppressed by inhibition of ERK1/2 signaling pathway in ectopic endometrial tissues in experimental mice model. CONCLUSION In conclusion, TRIM65 promotes invasion of ectopic EMS cells by activating a feedback loop with the ERK1/2/C-myc signaling pathway and may be a potential therapeutic target for EM.

Abstract
TRIM32 is a member of the tripartite motif (TRIM) family, which has been associated with tumorigenesis. However, its expression and potential functional role(s) in lung cancer progression have not been fully understood. To evaluate the relationship between the expression of TRIM32 and the prognosis of patients with lung cancer, an independent data set (The Human Protein Atlas website) was introduced. The expression and function analysis of TRIM32 in lung cancer cell lines were also performed by using cell counting kit-8, flow cytometry, transwell, real-time polymerase chain reaction and Western blot analysis. Our data showed that TRIM32 was overexpressed in lung cancer tissues and cell lines and was associated with a poor prognosis. TRIM32 silencing inhibited cell proliferation, migration, invasion, adhesion, and the activation of janus kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) signaling. The results showed knockdown of TRIM32 in NCI-H446 cells also inhibited cell growth in nude mice in the xenograft model. Additionally, TRIM32 overexpression promoted lung cancer cell proliferation and motility and mediated the expression of Bax, Bcl-2, cleaved caspase-3, matrix metalloproteinase-2 (MMP-2) and MMP-9 were inhibited by JAK2/STAT3 signaling inhibitor (AG490). Taken together, our findings suggest that TRIM32 may regulate lung cancer cell proliferation, apoptosis, and motility through activating the JAK2/STAT3-signaling pathway and may be a novel and promising target for lung cancer.

Abstract
AIMS To investigate the association of matrix metalloproteinase (MMP)-7 and MMP-9 with pelvic lymph node and para-aortic lymph node metastasis in early cervical cancer. METHODS A total of 137 patients with early cervical cancer (Stage Ia2-IIa2) were recruited from the Department of Gynecology and Obstetrics, Tumor Hospital of Liaoning Province from January 2009 to May 2014. We evaluated the expression of MMP-7 and MMP-9 by immunohistochemistry and their association with the clinicopathological parameters such as pelvic, common iliac and para-aortic lymph node metastasis. Spearman correlation was performed to analyze the correlation between MMP-7 and MMP-9 in cervical cancer. Finally, the areas under the receiver operating characteristic curve (ROC) of MMP-7 and MMP-9 in pelvic lymph node metastasis were assessed. RESULTS MMP-7 expression was significantly higher in patients with adenocarcinomas and adenosquamous carcinomas (P = 0.014), vascular cancer embolus (P = 0.041), pelvic lymph node metastasis (P = 0.000) and a higher level of Ki-67 (P = 0.000). MMP-9 expression was significantly associated with vascular cancer embolus (P = 0.003), depth of stromal invasion (P = 0.001), pelvic lymph node metastasis (P = 0.003), common iliac lymph node metastasis (P = 0.001) and para-aortic lymph nodes metastasis (P = 0.004). Coexpression of MMP-7 and MMP-9 was significantly associated with vascular cancer embolus (P < 0.001), higher expression of Ki-67 (P < 0.001) and pelvic lymph node metastasis (P < 0.001). Spearman correlation analysis indicated a positive correlation between MMP-7 and MMP-9 (r = 0.263, P = 0.002). Areas under the ROC of MMP-7 and MMP-9 were 0.707 and 0.646, respectively. CONCLUSION MMP-7 and MMP-9 expressions were associated with lymph node metastasis in patients with early cervical cancers, suggesting a positive correlation of MMP-7 and MMP-9 with invasive potential in early cervical cancers.

Abstract
Lung cancer is the most commonly diagnosed type of cancer worldwide. Although TRIM65 is an important protein involved in white matter lesion, the role of TRIM65 in human cancer remains less understood. Here, we reported that TRIM65 was significantly overexpressed in lung cancer tissues compared with adjacent normal lung tissues. Furthermore, TRIM65 expression was closely related to overall survival of patients with lung cancer. Knock down of TRIM65 in two lung cancer cell lines, SPC-A-1 and NCI-H358, resulted in a significant reduction in cell proliferation, migration, invasion and adhesion and a dramatic increase in G0-G1 phase arrest and apoptosis. In vivo tumorigenesis experiment also revealed that depletion of TRIM65 expression inhibited NCI-H358 cell growth. Moreover, based on gene set enrichment analysis (GSEA) with The Cancer Genome Atlas (TCGA) dataset, we found that TRIM65 was positive related to cell cycle, metastasis up and RHOA-REG pathways, which was further validated by RT-PCR and Western blot in TRIM65 knockdown lung cancer cells and indicated a possible mechanism underlying its effects on lung cancer. In summary, our study suggests that TRIM65 may work as an oncogene and a new effective therapeutic target for lung cancer treatment.

Abstract
Sirtuin6 (SIRT6), a member of the sirtuins protein family, plays multiple complex roles in cancer. Here, we report that elevated SIRT6 expression was correlated with clinicopathological parameters such as T and N classification in non-small cell lung cancer (NSCLC) patient tumors. SIRT6 overexpression in NSCLC cell lines increased extracellular signal-regulated kinase (p-ERK)1/2 phosphorylation, activated matrix metalloproteinase 9 (MMP9) and promoted tumor cell migration and invasion. Upon treatment with a specific mitogen-activated protein kinase (MEK) 1/2 inhibitor, these effects were abolished. Our results demonstrate SIRT6 upregulation in NSCLC for the first time and suggest a functional role for SIRT6 in promoting migration and invasion through ERK1/2/MMP9 signaling. SIRT6 may serve as a potential therapeutic target in NSCLC and its utility as a prognostic indicator warrants further study.

Abstract
To identify metastasis-related proteins in nasopharyngeal carcinoma (NPC), iTRAQ-tagging combined with 2D LC-MS/MS analysis was performed to identify the differentially expressed proteins (DEPs) in high metastatic NPC 5-8F cells and non-metastatic NPC 6-10B cells, and qRT-PCR and Western blotting were used to confirm DEPs. As a result, 101 DEPs were identified by proteomics, and 12 DEPs were selectively validated. We further detected expression of three DEPs (RAN, SQSTM1 and TRIM29) in a cohort of NPC tissue specimens to assess their value as NPC metastatic biomarkers, and found that combination of RAN, SQSTM1 and TRIM29 could discriminate metastatic NPC from non-metastatic NPC with a sensitivity of 88% and a specificity of 91%. TRIM29 and RAN expression level were closely correlated with lymph node and distant metastasis and clinical stage (P <0.05) in NPC patients. Finally, a combination of loss-of-function and gain-of-function approaches was performed to determine the effects of TRIM29 on NPC cell proliferation, migration, invasion and metastasis. The results showed that TRIM29 knockdown significantly attenuated while TRIM29 overexpression promoted NPC cell in vitro proliferation, migration and invasion and in vivo metastasis. The present data first time show that SQSTM1, RAN and TRIM29 are novel potential biomarkers for predicting NPC metastasis, demonstrate that TRIM29 is a metastasis-promoted protein of NPC.

Abstract
Transmembrane protein 17(TMEM17) is a newly identified protein, its expression pattern and clinicopathological relevance is still unclear. In this study, western blot assay was performed in 20 paired lung cancer samples and found that TMEM17 protein levels were lower in lung cancer tissues than that in the corresponding normal lung tissues (p=0.010). Immunohistochemistry staining in 143 cases lung cancer specimens also showed that TMEM17 expression in lung cancer tissues were significantly lower than adjacent normal lung tissues (35.7% vs 63.2%, p<0.001). And negative TMEM17 expression was significantly associated with poor histological differentiation (p=0.027), advanced TNM stages (p=0.006), positive lymph node metastasis (p=0.002) and poor prognosis (p=0.002). After overexpressing TMEM17, levels of p-ERK and its downstream molecules, p-P90RSK and Snail, were down-regulated, while levels of Occludin and Zo-1 were up-regulated, which result in the inhibition of invasion and migration ability of lung cancer cells. The effects were reversed by the incorporation of specific ERK inhibitor PD98059. In conclusion, loss of TMEM17 correlates with the development of non-small cell lung cancer (NSCLC) and predicts adverse clinical outcome of NSCLC patients. The effect of TMEM17 on inhibiting invasion and migration may attribute to restoring Occludin and Zo-1 expression through inactivating ERK-P90RSK-Snail pathway.

Abstract
The functionality and stability of the central nervous system (CNS) pabulum, called neural extracellular matrix (nECM), is paramount for the maintenance of a healthy network. The loosening or the damage of the scaffold disrupts synaptic transmission with the consequent imbalance of the neurotransmitters, reactive cells invasion, astrocytosis, new matrix deposition, digestion of the previous structure and ultimately, maladaptive plasticity with the loss of neuronal viability. nECM is constantly affected by CNS disorders, particularly in chronic modifying such as neurodegenerative disease, or in acute/subacute with chronic sequelae, like cerebrovascular and inflammatory pathology. Matrix metalloproteinases (MMPs) are the main interfering agent of nECM, guiding the balance of degradation and new deposition of proteins such as proteoglycans and glycoproteins, or glycosaminoglycans, such as hyaluronic acid. Activation of these enzymes is modulated by their physiologic inhibitors, the tissue inhibitors of MMPs or via other proteases inhibitors, as well as genetic or epigenetic up- or downregulation through molecular interaction or receptor activation. The appropriate understanding of the pathways underlying nECM modifications in CNS pathology is probably one of the pivotal future directions to identify the healthy brain network and subsequently design new therapies to interfere with the progression of the CNS disease and eventually find appropriate therapies.

Abstract
Colorectal cancer (CRC) is one of the most common malignancies worldwide. Tripartite motif-containing 29 (TRIM29) is a member of TRIM proteins family, which plays diverse physiological and pathological roles in humans. Recent studies found that TRIM29 expressed highly in CRC and promoted cell growth in vitro. However, its function in the metastasis of CRC has not been studied. In the present study, we confirmed the previous report that TRIM29 was upregulated in CRC tissues and high levels of TRIM29 expression were associated with poor overall survival of patients. Moreover, TRIM29 knockdown significantly reduced cancer cell proliferation via notably inducing cell cycle arrest and cell apoptosis. Silencing of TRIM29 significantly inhibited the migration and invasion ability of CRC cells. The protein levels of apoptosis‑, migration‑ and invasion‑related proteins were also changed after TRIM29 knockdown. Furthermore, phosphorylation levels of JAK2 and STAT3 were clearly reduced in TRIM29 knockdown cells, indicating a possible mechanism underlying its effects on colorectal carcinogenesis. Collectively, TRIM29 may exert oncogenic effects in CRC cells via regulating JAK2/STAT3 signaling.

Abstract
Vascular endothelial growth factor (VEGF), matrix metalloproteinase-9, and tissue inhibitor of metalloproteinase-1 may play a role in the pathogenesis of cancer disease. We investigated their levels and utility in comparison to cancer antigen (CA) 15-3 in patients with breast cancer (BC) and in relation to the control groups. The study included 100 women with BC, 50 patients with benign breast tumor, and 50 healthy women. The plasma levels of the tested parameters were determined using enzyme-linked immunosorbent assay, while CA 15-3 with chemiluminescent microparticle immunoassay. The results demonstrated significant differences in the concentration of the tested parameters and CA 15-3 between groups of patients with BC and healthy patients or patients with benign breast tumor. The plasma levels of VEGF and tissue inhibitor of metalloproteinase-1 were significantly higher in advanced tumor stages. The tested parameters were comparable to CA 15-3 values of the diagnostic sensitivity, specificity, the predictive values of positive and negative test results, and the area under the receiver-operating characteristic curve. The combined use of the tested parameters with CA 15-3 resulted in the increase in sensitivity, negative predictive value, and area under the receiver-operating characteristic curve, especially in the combination of VEGF with tumor marker (84%, 73%, 0.888, respectively). These findings suggest the usefulness of the tested parameters in the diagnosis of BC. VEGF, especially in combination with CA 15-3, showed the highest usefulness in the diagnosis of early BC.

Abstract
Tripartite motif-containing 29 (TRIM29) is a member of the tripartite motif (TRIM) protein family. TRIM29 has been reported to be deregulated in a number of cancer types, suggesting the oncogenic function of TRIM29. However, its clinical significance in non-small cell lung cancer (NSCLC) has not been fully elucidated. In the present study, the TRIM29 expression status was investigated by immunohistochemical analysis in paraffin-embedded specimens obtained from 320 patients with surgically resected NSCLC, treated between 2000 and 2007. High TRIM29 expression was significantly associated with smoking (P=0.012), T stage (P=0.015) and M stage (P=0.003). Furthermore, elevated TRIM29 expression level was correlated with reduced overall (OS) and disease-free survival. In addition, high TRIM29 expression was an independent prognostic factor for OS [P=0.003, hazard ratio (HR)=2.102, 95% confidence interval (CI), 1.069-3.193]. In conclusion, these results suggest that TRIM29 may be a useful prognostic marker in NSCLC patients and a potential molecular target for NSCLC treatment.

Abstract
Cell invasion and adhesion play an important role in cancer metastasis and are orchestrated by a complicated network of transcription factors including p63. Here, we show that a member of the tripartite motif protein family, TRIM29, is required for regulation of the p63-mediated pathway in cervical cancer cells. TRIM29 knockdown alters the adhesion and invasion activities of cervical cancer cells. TRIM29 knockdown and overexpression cause a significant decrease and increase of TAp63α expression, respectively. TRIM29 knockdown alters the expression pattern of integrins and increases ZEB1 expression. TRIM29 is required for suppression of an increase in the adhesion activity of cells by TAp63α. These findings suggest that TRIM29 regulates the p63-mediated pathway and the behavior of cervical cancer cells.

Abstract
Tripartite motif-containing 24 (TRIM24), also known as transcription intermediary factor 1-alpha (TIF1α), is a chromatin-associated protein which as been has been implicated in carcinogenesis. However, its expression profile and biological roles in human bladder carcinoma has not been investigated. In this study, we examined its expression in 95 bladder cancer specimens. We found that TRIM24 expression was upregulated in 39 of 95 (41.1 %) specimens compared with normal control. TRIM24 overexpression was associated with local invasion and advanced grade of bladder cancer. In addition, we transfected TRIM24 plasmid into BIU-87 cell line and TRIM24 siRNA into 5637 cell line. Colony formation, CCK-8, and transwell assay were used to assess its biological roles in bladder cancer cells. The result showed that TRIM24 could facilitate cancer cell growth and invading ability. Western blot analysis demonstrated that TRIM24 upregulated cyclin D1, cyclin E, p-IκBα, and p-AKT expression, suggesting TRIM24 activates NF-κB and AKT pathways. In addition, NF-κB inhibitor reversed the effect of TRIM24 on cyclin D1. In conclusion, TRIM24 is overexpressed in human bladder cancer and facilitates bladder cancer growth and invasion, possibly through NF-κB and AKT signaling pathways.

Abstract
The objective of the study was to investigate the impact of Numb on cell growth, cell migration, and invasion in human clear cell renal cell carcinoma (ccRCC). Endogenous expression of Numb was evaluated in the ccRCC cell lines (786-O, Caki-1, and Caki-2) and control reference human renal proximal tubular epithelial cells. Numb expression was decreased in the ccRCC cells compared with the control cells (P < 0.01). Then, 786-O and Caki-1 cells described as suitable transfection hosts were used in transfection to carry out biological function studies. The three experimental groups were as follows: Numb-ORF (transfected with Numb-ORF plasmid), blank-vector (transfected with pCMV6-entry), and cell-alone group (no DNA). Numb expression in the Numb-ORF groups was significantly higher than that in the controls (P < 0.01). Cell growth was remarkably reduced (P < 0.01), and the number of migrating or invading cells was reduced (P < 0.01) in the Numb-ORF groups compared with controls. Furthermore, the ratio of G0/G1 phase in the Numb-ORF group of 786-O cells was increased, and the S phase fraction and proliferation index was decreased (P < 0.01). Cyclin D1 and MMP-9 expression was reduced in the Numb-ORF groups compared with controls. Here, we have provided data for attenuated Numb expression in the ccRCC cells. Overexpression of Numb could induce G0/G1 phase arrest and inhibit cell proliferation, migration, and invasion. The suppressive effects might be due to downregulation of cyclin D1 or MMP-9 expression. Taken together, our data suggest that Numb may possibly function as a tumor suppressor involved in the carcinogenesis of ccRCC.

Abstract
The adapter protein CrkL is required for regulating the malignant potential of human cancers. However, the regulatory mechanisms of CrkL on the stromal cell-derived factor 1 (SDF-1)/CXCR4 signaling pathways in breast cancer are not well characterized. Here, CXCR4 and CrkL proteins were tested in breast cancer cell lines and 60 primary breast cancer tissues. In vitro, the roles of CrkL in SDF-1-induced MDA-MB-231 cell cycle, invasion and migration were investigated. In the present study, CXCR4 and CrkL were highly expressed in MCF-7, MDA-MB-231, MDA-MB-231HM MDA-MB-468 and tumor tissues (80 and 60 %, respectively) and closely correlated with lymph node metastasis. In vitro studies revealed that SDF-1 induced the activation of CrkL, Erk1/2, Akt and matrix metallopeptidase 9 (MMP9) in MDA-MB-231 cells. The si-CrkL treatment significantly down-regulated the phosphorylated Erk1/2 (p-Erk1/2) and MMP9, but up-regulated p-Akt, compared with control. Importantly, wound-healing and transwell invasion assays showed that si-CrkL significantly impaired the wound closure and inhibited the SDF-1-induced invasion; similarly, flow cytometry showed that si-CrkL affected cell cycle. In conclusion, these results suggest that CrkL plays a regulatory role in the SDF-1-induced Erk1/2 and PI3K/Akt pathways and further managed the invasion and migration of breast cancer cells. Thus, CrkL may be recommended as an interesting therapeutic target for breast cancer.

Abstract
BACKGROUND Naturally occurring agents, such as resveratrol, have been determined to benefit health. Numerous studies have demonstrated that resveratrol has antioxidative, cardioprotective, and neuroprotective properties. However, the effect of resveratrol exerts on the metastasis of oral cancer cells remains unclear. In this study, we investigated the effect the anti-invasive activity of resveratrol on a human oral cancer cell line (SCC-9) in vitro and the underlying mechanisms. METHODS Cell viability was examined by MTT assay, whereas cell motility was measured by migration and wound-healing assays. Zymography, reverse-transcriptase polymerase chain reaction (PCR), and promoter assays confirmed the inhibitory effects of resveratrol on matrix metalloproteinase-9 (MMP-9) expression in oral cancer cells. RESULTS We established that various concentrations (0-100 μM) of resveratrol inhibited the 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced migration capacities of SCC-9 cells and caused no cytotoxic effects. Zymography and Western blot analyses suggested that resveratrol inhibited TPA-induced MMP-9 gelatinolytic activity and protein expression. In addition, the results indicated that resveratrol inhibited the phosphorylation of c-Jun N-terminal kinase (JNK)1/2 and extracellular-signal-regulated kinase (ERK)1/2 involved in downregulating protein expression and the transcription of MMP-9. CONCLUSION In summary, resveratrol inhibited MMP-9 expression and oral cancer cell metastasis by downregulating JNK1/2 and ERK1/2 signals pathways and, thus, exerts beneficial effects in chemoprevention.

Abstract
As the most aggressive malignant primary human brain tumor, glioblastoma is noted with extremely poor patient survival. Previous studies have demonstrated that expression of matrix metalloproteinase-9 (MMP9) in glioblastoma cells is critical for cancer metastasis. However, the molecular signaling pathways that control MMP9 activation remain undefined. Here, we reported a strong negative correlation of microRNA (miRNA)-181c levels with either MMP9 levels or activation of epidermal growth factor receptor (EGFR) signaling in glioblastoma patients. EGF-induced activation of EGFR in a human glioblastoma line, A-172 cells, increased MMP9 expression through activation of phosphatidylinositol 3-kinase (PI3K)/Akt pathway, without affecting expression of miRNA-181c. On the other hand, overexpression of miRNA-181c in A-172 cells inhibited MMP9 expression by inhibiting Akt phosphorylation, but not phosphorylation of EGFR receptor. Taken together, these findings suggest that EGFR signaling activates downstream PI3K/Akt to increase MMP9 expression in glioblastoma, while phosphorylation of Akt is a control point by miRNA-181c. Our work thus provides new insights into the molecular basis underlying the metastasis of glioblastoma.

Abstract
Diversin was recently reported to play roles in Wnt and JNK pathways. However, the expression pattern and biological roles of diversin in human breast cancer have not been reported. In the present study, we found that diversin was overexpressed in breast cancer specimens by immunohistochemistry and western blot. Significant association was observed between diversin overexpression and TNM stage (p = 0.0036), nodal metastasis (p = 0.0033), negative estrogen receptor expression (p = 0.0012) and triple-negative status (p = 0.0017). Furthermore, colony formation assay and matrigel invasion assay showed that knockdown of diversin expression in MDA-MB-231 cell line with high endogenous expression decreased cell proliferation and cell invasion. Transfection of diversin plasmid in MCF-7 cell line increased cell proliferation and invasion. Further analysis showed that diversin depletion downregulated JNK phosphorylation while its overexpression upregulated JNK phosphorylation. In conclusion, our study demonstrated that diversin was overexpressed in human breast cancers. Diversin could contribute to breast cancer cell proliferation and invasion.

Abstract
Previous study indicated diversin overexpression in human cancers. However, its expression pattern in human gliomas and the molecular mechanisms of diversin on cancer progression have not been characterized. In the present study, diversin expression was investigated in 105 glioma specimens using immunohistochemistry. Negative staining was observed in normal glial cells, and positive staining was found in 33 out of 105 (31.4 %) glioma specimens. Diversin overexpression correlated with advanced tumor grade (p < 0.05). Small interfering RNA (siRNA) knockdown was performed in U87 and TG905 cell lines with high endogenous diversin expression. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and colony formation assay showed that diversin knockdown inhibited glioma cell growth. Matrigel invasion assay showed that diversin depletion inhibited cell invasion. In addition, messenger RNA (mRNA) and protein levels of matrix metallopeptidase 9 (MMP9) were downregulated after siRNA treatment. In conclusion, diversin is overexpressed in human glioma and regulates glioma cell proliferation and invasion, possibly through MMP9.

Abstract
Glioblastoma is the most aggressive malignant primary brain tumor in humans, with extremely poor patient survival. Although previous studies have demonstrated that expression of matrix metalloproteinase-9 (MMP9) in glioblastoma promotes cancer metastasis, the upstream molecular signaling cascades that control activation of MMP9 remain largely unknown. Here, we used a human glioblastoma line, A-172, to examine molecular signaling to activate MMP9. We found that epidermal growth factor (EGF)-induced activation of epidermal growth factor receptor (EGFR) in A-172 cells activated MMP9, resulting in an increase in cancer invasiveness. A specific inhibitor for EGFR efficiently blocked EGF-induced activation of MMP9 and then cancer invasiveness. Moreover, an inhibitor for phosphatidylinositol 3-kinase (PI-3 K)/protein kinase B (Akt) significantly inhibited the EGF-induced activation of MMP9. Furthermore, nuclear exclusion of a major Akt downstream target, Forkhead box protein O1 (FoxO1), was induced by Akt activation, which could be inhibited by either an EGFR inhibitor or by PI-3 K/Akt inhibitor. An expression of a constitutive nuclear form of FoxO1 significantly inhibited MMP9 activation induced by EGF. Taken together, these findings suggest that EGF/EGFR signaling activates downstream PI-3 K/Akt to induce FoxO1 nuclear exclusion, which activates MMP9 to promote glioblastoma invasiveness. Thus, FoxO1 appears to be a novel therapeutic target for inhibiting metastasis of glioblastoma.

TRIM29 as a novel biomarker in pancreatic adenocarcinoma. DISEASE MARKERS 2014; 2014:317817.

Abstract
Background and Aim. Tripartite motif-containing 29 (TRIM29) is structurally a member of the tripartite motif family of proteins and is involved in diverse human cancers. However, its role in pancreatic cancer remains unclear. Methods. The expression pattern of TRIM29 in pancreatic ductal adenocarcinoma was assessed by immunocytochemistry. Multivariate logistic regression analysis was used to investigate the association between TRIM29 and clinical characteristics. In vitro analyses by scratch wound healing assay and invasion assays were performed using the pancreatic cancer cell lines. Results. Immunohistochemical analysis showed TRIM29 expression in pancreatic cancer tissues was significantly higher (n = 186) than that in matched adjacent nontumor tissues. TRIM29 protein expression was significantly correlated with lymph node metastasis (P = 0.019). Patients with positive TRIM29 expression showed both shorter overall survival and shorter recurrence-free survival than those with negative TRIM29 expression. Multivariate analysis revealed that TRIM29 was an independent factor for pancreatic cancer over survival (HR = 2.180, 95% CI: 1.324–4.198, P = 0.011). In vitro, TRIM29 knockdown resulted in inhibition of pancreatic cancer cell proliferation, migration, and invasion. Conclusions. Our results indicate that TRIM29 promotes tumor progression and may be a novel prognostic marker for pancreatic ductal adenocarcinoma.

Abstract
The molecular mechanism underlying activation of matrix metallopeptidase 9 (MMP9) in non-small cell lung cancer (NSCLC) cells, which controls cancer invasiveness and metastasis, remains elusive. Here, we reported a strong correlation of epidermal growth factor receptor (EGFR) and MMP9 levels in NSCLC patients. Thus, we used a human NSCLC line, A549, to examine whether there is a causal link between EGFR and MMP9 activation. We found that EGF-induced activation of EGFR in A549 cells activated MMP9, resulting in an increase in cancer invasiveness. An EGFR inhibitor efficiently blocked this EGF-induced activation of MMP9 and, consequently, increased cancer invasiveness. Moreover, an inhibitor for phosphatidylinositol 3-kinase (PI3K)/Akt, but not an inhibitor for mitogen-activated protein kinase, or an inhibitor for Jun N-terminal kinase, significantly inhibited the epidermal growth factor (EGF)-induced activation of MMP9, suggesting that PI3K/Akt signaling cascades may be responsible for EGF-activated MMP9. We further dissected the pathway and found that nuclear exclusion of a major Akt downstream target, FoxO1, occurred by EGF-induced Akt activation, which could be inhibited by either EGFR inhibitor or by PI3K/Akt inhibitor. In a loss of function, expression of a constitutive nuclear form of FoxO1 significantly inhibited MMP9 activation induced by EGF. Taken together, these findings suggest that EGF/EGFR signaling activates downstream PI3K/Akt to induce FoxO1 nuclear exclusion, which activates MMP9 to promote NSCLC invasiveness. Thus, Akt and FoxO1, in addition to the well-known EGFR, appear to be promising therapeutic targets for preventing the metastasis of NSCLC.

Telmisartan exerts anti-tumor effects by activating peroxisome proliferator-activated receptor-γ in human lung adenocarcinoma A549 cells. Molecules 2014; 19:2862-76.

Abstract
Telmisartan, a member of the angiotensin II type 1 receptor blockers, is usually used for cardiovascular diseases. Recent studies have showed that telmisartan has the property of PPARγ activation. Meanwhile, PPARγ is essential for tumor proliferation, invasion and metastasis. In this work we explore whether telmisartan could exert anti-tumor effects through PPARγ activation in A549 cells. MTT and trypan blue exclusion assays were included to determine the survival rates and cell viabilities. RT-PCR and western blotting were used to analyze the expression of ICAM-1, MMP-9 and PPARγ. DNA binding activity of PPARγ was evaluated by EMSA. Our data showed that the survival rates and cell viabilities of A549 cells were all reduced by telmisartan in a time- and concentration-dependent manner. Meanwhile, our results also demonstrated that telmisartan dose-dependently inhibited the expression of ICAM-1 and MMP-9. Moreover, the cytotoxic and anti-proliferative effects, ICAM-1 and MMP-9 inhibitive properties of telmisartan were totally blunted by the PPARγ antagonist GW9662. Our findings also showed that the expression of PPARγ was up-regulated by telmisartan in a dose dependent manner. And, the EMSA results also figured out that DNA binding activity of PPARγ was dose-dependently increased by telmisartan. Additionally, our data also revealed that telmisartan-induced PPARγ activation was abrogated by GW9662. Taken together, our results indicated that telmisartan inhibited the expression of ICAM-1 and MMP-9 in A549 cells, very likely through the up-regulation of PPARγ synthesis.
