Interleukin-1β triggers matrix metalloprotease-3 expression through p65/RelA activation in melanoma cells. PLoS One 2022; 17:e0278220. [PMID: 36445856 PMCID: PMC9707762 DOI: 10.1371/journal.pone.0278220] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2022] [Accepted: 11/11/2022] [Indexed: 12/02/2022] Open
Abstract
Melanoma shows highly aggressive behavior (i.e., local invasion and metastasis). Matrix metalloprotease-3 (MMP-3), a zinc-dependent endopeptidase, degrades several extracellular substrates and contributes to local invasion by creating a microenvironment suitable for tumor development. Here, we report that interleukin-1β (IL-1β) triggers the MMP-3 expression in canine melanoma cells. The activity of MMP-3 in the culture supernatant was increased in IL-1β-treated melanoma cells. IL-1β time- and dose-dependently provoked the mRNA expression of MMP-3. IL-1β induced the migration of melanoma cells; however, this migration was attenuated by UK356618, an MMP-3 inhibitor. When the cells were treated with the nuclear factor-κB (NF-κB) inhibitor TPCA-1, the inhibition of MMP-3 expression was observed. In IL-1β-treated cells, the phosphorylation both of p65/RelA and p105 was detected, indicating NF-κB pathway activation. In p65/RelA-depleted melanoma cells, IL-1β-mediated mRNA expression of MMP-3 was inhibited, whereas this reduction was not observed in p105-depleted cells. These findings suggest that MMP-3 expression in melanoma cells is regulated through IL-1β-mediated p65/RelA activation, which is involved in melanoma cell migration.

Genetic Variants of Matrix Metalloproteinase and Sepsis: The Need Speed Study. Biomolecules 2022; 12:biom12020279. [PMID: 35204780 PMCID: PMC8961575 DOI: 10.3390/biom12020279] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2022] [Revised: 02/04/2022] [Accepted: 02/04/2022] [Indexed: 12/12/2022] Open
Abstract
Many causal mechanisms in sepsis susceptibility are largely unknown and the functional genetic polymorphisms (GP) of matrix metalloproteinases (MMPs) and their natural tissue inhibitor of MMPs (TIMP1) could play a role in its development. GPs of MMPs and TIMP (namely MMP-1 rs1799750, MMP-3 rs3025058, MMP-8 rs11225395, MMP-9 rs2234681, and TIMP-1 rs4898) have been compared in 1058 patients with suspected sepsis to assess the association with susceptibility and etiology of sepsis. Prevalence of MMP8 rs11225395 G/G genotype was higher in sepsis patients than in those with non-infective Systemic Inflammatory Reaction Syndrome (35.6 vs. 26%, hazard ratio, HR 1.56, 95% C.I. 1.04–2.42, p = 0.032). G/G patients developed less hyperthermia (p = 0.041), even after stratification for disease severity (p = 0.003). Patients carrying the 6A allele in MMP3 rs3025058 had a higher probability of microbiologically-proven sepsis (HR 1.4. 95%C.I. 1.01–1.94, p = 0.044), particularly when due to virus (H.R. 2.14, 95% C.I. 1.06–4.31, p = 0.046), while MMP-1 G/G genotype patients carried a higher risk for intracellular bacteria (Chlamydia, Mycoplasma, and Legionella, H.R. 6.46, 95% C.I. 1.58–26.41, p = 0.003). Neither severity of sepsis at presentation, nor 30-day mortality were influenced by the investigated variants or their haplotype. MMP8 rs11225395 G/G carriers have lower temperature at presentation and a more than 50% increased susceptibility to sepsis. Among patients with sepsis, carriers of MMP1 rs1799750 G/G have an increased susceptibility for intracellular pathogen infections, while virus serology is more often positive in those with the MMP3 rs3025058 A/A genotype.

Abstract
To defense harmful stimuli or maintain the immune homeostasis, the body produces and recruits a superfamily of cytokines such as interleukins, interferons, chemokines etc. Among them, chemokines act as crucial regulators in defense systems. CCL5/CCR5 combination is known for facilitating inflammatory responses, as well as inducing the adhesion and migration of different T cell subsets in immune responses. In addition, recent studies have shown that the interaction between CCL5 and CCR5 is involved in various pathological processes including inflammation, chronic diseases, cancers as well as the infection of COVID-19. This review focuses on how CCL5/CCR5 axis participates in the pathological processes of different diseases and their relevant signaling pathways for the regulation of the axis. Moreover, we highlighted the gene therapy and chemotherapy studies for treating CCR5-related diseases, including the ongoing clinical trials. The barriers and perspectives for future application and translational research were also summarized.

Abstract
The single nucleotide polymorphism (SNP) of the promoter region of MMP-1 (at 1607 bp) and MMP-3 (at 1171 bp) create Ets binding sites. Correlations between these SNPs and sensitivity to several biological processes such as metastasis and recurrence of cancer have been reported in several studies. In this case-control study, we looked for these SNPs in women infected with or not with high-risk human papillomaviruses (HR-HPV). The frequency, distribution and correlation of these SNPs with the presence or absence of HR-HPV infection were evaluated. Genotypes 1G1G, 1G2G and 2G2G for MMP1 and genotypes 5A5A, 5A6A, 6A6A for MMP3 were found in our study population. In general, we noted that the 1G (40.8%) and 2G (64.8%) alleles were more frequent in non-infected women and infected women, respectively, and more specifically this difference was significant in women from Côte d'Ivoire. These results, although yet to be reaffirmed with assays for quantifying the mRNA of these genes, suggest that the SNP of the MMP-1 promoter could promote infection with HR-HPV.

Role of S100 proteins in health and disease. BIOCHIMICA ET BIOPHYSICA ACTA-MOLECULAR CELL RESEARCH 2020; 1867:118677. [PMID: 32057918 DOI: 10.1016/j.bbamcr.2020.118677] [Citation(s) in RCA: 152] [Impact Index Per Article: 38.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/27/2019] [Revised: 01/22/2020] [Accepted: 02/09/2020] [Indexed: 12/16/2022]
Abstract
The S100 family of proteins contains 25 known members that share a high degree of sequence and structural similarity. However, only a limited number of family members have been characterized in depth, and the roles of other members are likely undervalued. Their importance should not be underestimated however, as S100 family members function to regulate a diverse array of cellular processes including proliferation, differentiation, inflammation, migration and/or invasion, apoptosis, Ca2+ homeostasis, and energy metabolism. Here we detail S100 target protein interactions that underpin the mechanistic basis to their function, and discuss potential intervention strategies targeting S100 proteins in both preclinical and clinical situations.

Abstract
Tumorigenesis is a result of uncontrollable cell proliferation which is regulated by a variety of complex factors including miRNAs. The initiation and progression of cancer are always accompanied by the dysregulation of miRNAs. However, the underlying mechanism of miRNA dysregulation in cancers is still largely unknown. Herein we found that miR-100 was inordinately upregulated in the sera of patients with gastric cancer, indicating that miR-100 might emerge as a biomarker for the clinical diagnosis of cancer. The abnormal expression of miR-100 in gastric cancer cells was mediated by a novel transcription factor NME2 (NME/NM23 nucleoside diphosphate kinase 2). Further data revealed that the transcription factor NME2 could promote the transcriptions of antiapoptotic genes including miRNA (i.e., miR-100) and protein-encoding genes (RIPK1, STARD5, and LIMS1) through interacting with RNA polymerase II and RNA polymerase II-associated protein 2 to mediate the phosphorylation of RNA polymerase II C-terminal domain at the 5th serine, leading to the suppression of apoptosis of gastric cancer cells both in vitro and in vivo. In this context, our study revealed that the transcription factor NME2 is a master suppressor for apoptosis of gastric cancer cells. IMPLICATIONS: Our study contributed novel insights into the mechanism involved in the expression regulation of apoptosis-associated genes and provided a potential biomarker of gastric cancer.

Interferon regulatory factor 5 (IRF5) regulates the expression of matrix metalloproteinase-3 (MMP-3) in human chondrocytes. Int Immunopharmacol 2017; 55:231-236.

Abstract
Matrix metalloproteinase-3 (MMP-3) plays a pivotal role in the destruction of articular cartilage in osteoarthritis (OA). The regulation of gene expression of MMP-3 is complicated. Interferon regulatory factor 5 (IRF5) is a member of the interferon regulatory factor family of transcription factors. Little information regarding the biological function of IRF5 on chondrocytes and the pathogenesis of OA has been reported. In the current study, for the first time, we report that IRF5 is expressed in human primary chondrocytes and human chondrosarcoma cell line SW1353 cells. In addition, IRF5 is upregulated in response to TNF-α treatment in a dose dependent manner. Interestingly, IRF5 is significantly higher in chondrocytes from OA patients compared to those from normal subjects. Notably, IRF5 mediates TNF-α- induced expression of MMP-3 in chondrocytes. Overexpression of IRF5 promotes the expression of MMP-3, however, knockdown of IRF5 reduces the expression of MMP-3. Mechanistically, IRF5 is able to enhance the transcription of MMP-3 by binding to its promoter. Also, we found that NF-κB was involved in the effects of IRF-5 on MMP-3 expression. These findings suggest that IRF5 might be a novel pharmacological target for the treatment of OA and RA.

Reactive oxygen species-mediated switching expression of MMP-3 in stromal fibroblasts and cancer cells during prostate cancer progression. Sci Rep 2017; 7:9065.

Abstract
Studies on the aberrant control of extracellular matrices (ECMs) have mainly focused on the role of malignant cells but less on that of stromal fibroblasts during cancer development. Herein, by using paired normal and prostate cancer-associated stromal fibroblasts (CAFs) derived from a coculture cell model and clinical patient samples, we demonstrated that although CAFs promoted prostate cancer growth, matrix metalloproteinase-3 (MMP-3) was lower in CAFs but elevated in prostate cancer cells relative to their normal counterparts. Furthermore, hydrogen peroxide was characterized as the central modulator for altered MMP-3 expression in prostate cancer cells and CAFs, but through different regulatory mechanisms. Treatment of CAFs but not prostate cancer cells with hydrogen peroxide directly inhibited mmp-3 promoter activity with concomitant nuclear translocation of nuclear factor-κB (NF-κB), indicating that NF-κB is the downstream pathway for the transcriptional repression of MMP-3 in CAFs. Hydrogen peroxide reduced thrombospondin 2 (an MMP-3 suppressor) expression in prostate cancer cells by upregulating microRNA-128. To the best of our knowledge, this is the first study to demonstrate the crucial role of reactive oxygen species in the switching expression of MMP-3 in stromal fibroblasts and prostate cancer cells during tumor progression, clarifying how the tumor microenvironment modulates ECM homeostasis control.

Abstract
Tuberculosis (TB) causes disease worldwide, and multidrug resistance is an increasing problem. Matrix metalloproteinases (MMPs), particularly the collagenase MMP-1, cause lung extracellular matrix destruction, which drives disease transmission and morbidity. The role in such tissue damage of the stromelysin MMP-10, a key activator of the collagenase MMP-1, was investigated in direct Mycobacterium tuberculosis (Mtb)-infected macrophages and in conditioned medium from Mtb-infected monocyte-stimulated cells. Mtb infection increased MMP-10 secretion from primary human macrophages 29-fold, whereas Mtb-infected monocytes increased secretion by 4.5-fold from pulmonary epithelial cells and 10.5-fold from fibroblasts. Inhibition of MMP-10 activity decreased collagen breakdown. In two independent cohorts of patients with TB from different continents, MMP-10 was increased in both induced sputum and bronchoalveolar lavage fluid compared with control subjects and patients with other respiratory diseases (both P < 0.05). Mtb drove 3.5-fold greater MMP-10 secretion from human macrophages than the vaccine strain bacillus Calmette-Guerin (P < 0.001), whereas both mycobacteria up-regulated TNF-α secretion equally. Using overlapping, short, linear peptides covering the sequence of early secretory antigenic target-6, a virulence factor secreted by Mtb, but not bacillus Calmette-Guerin, we found that stimulation of human macrophages with a single specific 15-amino acid peptide sequence drove threefold greater MMP-10 secretion than any other peptide (P < 0.001). Mtb-driven MMP-10 secretion was inhibited in a dose-dependent manner by p38 and extracellular signal-related kinase mitogen-activated protein kinase blockade (P < 0.001 and P < 0.01 respectively), but it was not affected by inhibition of NF-κB. In summary, Mtb activates inflammatory and stromal cells to secrete MMP-10, and this is partly driven by the virulence factor early secretory antigenic target-6, implicating it in TB-associated tissue destruction.

Abstract
BACKGROUND Histone deacetylase 3 (HDAC3) is overexpressed in cancers and its inhibition enhances anti-tumor chemotherapy. ZBP-89, a transcription factor, can induce pro-apoptotic Bak and reduce HDAC3 but the mechanism is unknown. Pin1, a molecular switch that determines the fate of phosphoproteins, is known to interact with HDAC3. The aim of this study was to investigate the mechanism how ZBP-89 downregulated HDAC3. METHODS In this study, liver cells, Pin1-knockout Pin1(-/-) and Pin1 wild-typed Pin(+/+) cells were used to explore how ZBP-89 reduced HDAC3. The overexpression of ZBP-89 was achieved by infecting cells with Ad-ZBP-89, an adenoviral construct containing ZBP-89 gene. The role of NF-κB was determined using CAY10576, MG132 and SN50, the former two being inhibitors of IκB degradation and SN50 being an inhibitor of p65/p50 translocation. A xenograft tumor model was used to confirm the in vitro data. RESULTS ZBP-89 reduced HDAC3, and it could form a complex with IκB and induce IκB phosphorylation to inhibit IκB. Furthermore, ZBP-89-mediated HDAC3 reduction was suppressed by IκB degradation inhibitors CAY10576 and MG132 but not by p65/p50 translocation inhibitor SN50, indicating that IκB decrease rather than the elevated activity of NF-κB contributed to HDAC3 reduction. ZBP-89-mediated HDAC3 or IκB reduction was significantly less obvious in Pin1(-/-) cells compared with Pin1(+/+) cells. In Ad-ZBP-89-infected Pin1(+/+) cancer cells, Pin1 siRNA increased HDAC3 but decreased Bak, compared with cells without ZBP-89 infection. These findings indicate that Pin1 participates in ZBP-89-mediated HDAC3 downregulation and Bak upregulation. The cell culture result was confirmed by in vivo mouse tumor model experiments. CONCLUSIONS ZBP-89 attenuates HDAC3 by increasing IκB degradation. Such attenuation is independent of NF-κB activity but partially depends on Pin1. The novel pathway identified may help generate new anti-cancer strategy by targeting HDAC3 and its related molecules.

Oncogenesis 2014; 3:e116. [PMID: 25133483 PMCID: PMC5189963 DOI: 10.1038/oncsis.2014.28] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2014] [Revised: 06/30/2014] [Accepted: 07/02/2014] [Indexed: 12/17/2022] Open
Abstract
The factors that determine the ability of metastatic tumor cells to expand and grow in specific secondary site(s) are not yet fully understood. Matrix metalloproteinases (MMP) were identified as potential regulators of the site-specificity of metastasis. We found that lung carcinoma cells ectopically expressing high levels of the receptor for the type I insulin like growth factor receptor (M27R cells) had a significant reduction in MMP-3 expression levels and this coincided with reduced metastasis to the lung. We used these cells to further investigate signaling pathways regulating MMP-3 expression and the role that MMP-3 plays in lung metastasis. We show that ectopic IκB kinase ɛ (IKKɛ) expression in these cells partly restored MMP-3 expression levels and also sensitized MMP-3 transcription to induction by phorbol 12-myristate 13-acetate (PMA). This increase in MMP-3 production was due to increased activation of several signal transduction mediators, including protein kinase C alpha, ERK2, Akt and the transcription factor p65. Furthermore, reconstitution of MMP-3 expression in M27R cells restored their ability to colonize the lung whereas silencing of MMP-3 in M27 cells reduced metastases. Collectively, our results implicate IKKɛ as a central regulator of PMA-induced cell signaling and MMP-3 expression and identify MMP-3 as an enabler of tumor cell expansion in the lung.

Abstract
Background Ionizing radiation (IR) in combination with microtubule stabilizing agents (MSA) is a promising combined treatment modality. Supra-additive treatment responses might result from direct tumor cell killing and cooperative indirect, tumor cell-mediated effects on the tumor microenvironment. Here we investigated deregulation of matrix metalloproteinase (MMP) activity, as an important component of the tumor microenvironment, by the combined treatment modality of IR with the clinically relevant MSA patupilone. Methods Expression, secretion and activity of MMPs and related tissue inhibitors of metalloproteinases (TIMPs) were determined in cell extracts and conditioned media derived from human fibrosarcoma HT1080 and human glioblastoma U251 tumor cells in response to treatment with IR and the MSA patupilone. Treatment-dependent changes of the invasive capacities of these tumor cell lines were analysed using a Transwell invasion assay. Control experiments were performed using TIMP-directed siRNA and TIMP-directed inhibitory antibodies. Results Enzymatic activity of secreted MMPs was determined after treatment with patupilone and irradiation in the human fibrosarcoma HT1080 and the human glioblastoma U251 tumor cell line. IR enhanced the activity of secreted MMPs up to 2-fold and cellular pretreatment with low dose patupilone (0.05-0.2 nM) counteracted specifically the IR-induced MMP activity. The cell invasive capacity of HT1080 and U251 cells was increased after irradiation with 2 Gy by 30% and 50%, respectively, and patupilone treatment completely abrogated IR-induced cell invasion. Patupilone did not alter the level of MMP expression, but interestingly, the protein level of secreted TIMP-1 and TIMP-2 was lower after combined treatment than after irradiation treatment alone. Furthermore, siRNA depletion of TIMP-1 or TIMP-2 prevented IR-mediated induction of MMP activity and cell invasion. Conclusions These results indicate that patupilone counteracts an IR-induced MMP activation process by the reduction of secreted TIMP-1 and TIMP-2 proteins, which are required for activation of MMPs. Since IR-induced MMP activity could contribute to tumor progression, treatment combination of IR with patupilone might be of great clinical benefit for tumor therapy.

IL-4 inhibition of IL-1 induced Matrix metalloproteinase-3 (MMP-3) expression in human fibroblasts involves decreased AP-1 activation via negative crosstalk involving of Jun N-terminal kinase (JNK). Exp Cell Res 2013; 319:1398-408.

Abstract
Matrix metalloproteinase-3 (MMP-3) over-expression is associated with tissue destruction in the context of chronic inflammation. Previous studies showed that IL-4 inhibits induction of MMP-3 by IL-1β, and suggested that AP-1 might be involved. Here we show that IL-1 induced binding of transcription factor AP-1 to the MMP-3 promoter consists primarily of c-Jun, JunB, and c-Fos and that binding of c-Jun and c-Fos is inhibited by the combination of cytokines while binding of Jun B is not. Mutation of the AP-1 site in the MMP-3 promoter decreased the ability of IL-4 to inhibit its transcription in transfected MG-63 cells. Western blotting showed that both cytokines activate Jun N-terminal kinase (JNK), but with somewhat different kinetics, and that activation of JNK by both cytokines individually is inhibited by the combination. These results indicate that IL-4 inhibition of MMP-3 expression is associated with reduction of IL-1 induced binding of active forms of the AP-1 dimer, while less active JunB-containing dimers remain, and suggest that these changes are associated with decreased activation of JNK.

Abstract
AIMS Estrogen-dependent hyperplasia of myo- and endometrium manifests as uterine leiomyoma or adenomyosis. We studied possible associations between common polymorphisms of matrix metalloproteinase (MMP) genes and clinical features of uterine hyperplasia. PATIENTS AND METHODS One hundred seventy female patients with uterine leiomyoma (46.6±0.5 years) were observed. Clinical diagnosis was based on physical examination, ultrasonography, and histological data. MMP-1 (-1607 1G/2G, rs1799750) and MMP-3 (-1171 5A/6A, rs3025058) were genotyped with allele-specific polymerase chain reaction (PCR) of leukocyte DNA. Clinical and genetic data were evaluated using nonparametric statistics. RESULTS Distributions of MMP-1 and MMP-3 promoter alleles among patients and population controls were similar and corresponded to the Hardy-Weinberg equilibrium (HWE). Detectable tumor growth and adenomyosis were observed, respectively, in 71% and 55% of cases. Steady-state leiomyoma correlated with a higher prevalence of the MMP-1 1G/1G genotype (p=0.02 by χ(2) test). Accelerated tumor growth correlated with higher frequency of the MMP-1 2G allele [odds ratio (OR)=2.048, p=0.039, χ(2)=4.2611, confidence interval (CI)=(1.032-4.062)]. MMP-1 2G was also associated with multinodular growth [OR=3.561, p=0.01249, χ(2)=6.24, CI=(1.261-10.058)]. The MMP-1 2G allele tended to increase in patients with adenomyosis [OR=1.525, p=0.054, χ(2)=3.71, CI=(0.992-2.345)]. CONCLUSION Our pilot study suggests that the 2G (-1607)MMP-1 genotype may be a potential risk marker of myo- and endometrial hyperplasia.

Abstract
BACKGROUND AND PURPOSE In Parkinson's disease, the dopaminergic neurones in the substantia nigra undergo degeneration. While the exact mechanism for the degeneration is not completely understood, neuronal apoptosis and neuroinflammation are thought to be key contributors. We have recently established that MMP-3 plays crucial roles in dopaminergic cell death and microglial activation. EXPERIMENTAL APPROACH We tested the effects of 7-hydroxy-6-methoxy-2-propionyl-1,2,3,4-tetrahydroisoquinoline (PTIQ) on expression of MMP-3 and inflammatory molecules and dopaminergic cell death in vitro and in an animal model of Parkinson's disease, and Parkinson's disease-related motor deficits. The pharmacokinetic profile of PTIQ was also evaluated. KEY RESULTS PTIQ effectively suppressed the production of MMP-3 induced in response to cellular stress in the dopaminergic CATH.a cell line and prevented the resulting cell death. In BV-2 microglial cells activated with lipopolysaccharide, PTIQ down-regulated expression of MMP-3 along with IL-1β, TNF-α and cyclooxygenase-2 and blocked nuclear translocation of NF-κB. In the mouse model of Parkinson's disease ,induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP), PTIQ attenuated the associated motor deficits, prevented neurodegeneration and suppressed microglial activation in the substantia nigra. Pharmacokinetic analysis showed it was relatively stable against liver microsomal enzymes, did not inhibit the cytochrome p450 isozymes or the hERG ion channel, exhibited no cytotoxicity on liver cells or lethality when administered at 1000 mg kg(-1) and entered the brain rather rapidly yielding a 28% brain:plasma ratio after i.p. injection. CONCLUSIONS AND IMPLICATIONS These results suggest PTIQ has potential as a candidate drug for disease-modifying therapy for Parkinson's disease.

Abstract
Combined radiochemotherapy treatment modalities are in use for many indications and therefore of high interest. Even though a combined modality in clinical use is often driven by pragmatic aspects, mechanistic preclinical-based concepts of interaction are of importance in order to translate and implement an optimal combination and scheduling of two modalities into the clinics. The use of microtubule stabilising agents is a promising strategy for anti-cancer therapy as a part of combined treatment modality with ionising radiation. Traditionally, microtubule targeting agents are classified as cytotoxic chemotherapeutics and are mostly used in a maximally tolerated dose regimen. Apart from direct cytotoxicity and similar to mechanisms of molecular targeting agents, microtubule stabilising agents interfere with multiple cellular processes, which can be exploited as part of combined treatment modalities. Recent preclinical investigations on the combination of ionising radiation and microtubule stabilising agents reveal new mechanistic interactions on the cellular and tumour level and elucidate the supra-additive tumour response observed particularly in vivo. The major focus on the mechanism of interaction was primarily based on radiosensitisation due to cell cycle arrest in the most radiosensitive G2/M-phase of the cell cycle. However, other mechanisms of interaction such as reoxygenation and direct as well as indirect endothelial damage have also been identified. In this review we summarise and allocate additive and synergistic effects induced by the combined treatment of clinically relevant microtubule stabilising agents and ionising radiation along a described radiobiological framework encompassing distinct mechanisms relevant for exploiting the combination of drugs and ionising radiation.

Abstract
Interleukin-6 (IL-6) is a pleiotropic cytokine that plays a central role in host defense. IL-6 expression can be regulated at both a transcriptional and a post-transcriptional level. We used a combination of bioinformatics and experimental techniques to demonstrate that the miR-365 is a direct negative regulator of IL-6. Overexpression of miR-365 mimics decreased activity of a luciferase reporter containing the IL-6 3'-UTR and led to repression of IL-6 protein. In contrast, ectopic expression of a miR-365 inhibitor elevated IL-6 expression. The negative regulation of miR-365 was strictly dependent on a microRNA binding element in the 3'-UTR of IL-6 mRNA. Deletion mutant analysis of the miR-365 promoter showed that two transcription factors, Sp1 and NF-κB, are essential for the transcriptional regulation of miR-365. We also demonstrate that the MAPK/ERK pathway contributes to the regulation of miR-365. Furthermore, miR-365 exhibited a greater negative regulatory effect on IL-6 than hsa-let-7a, a previously identified microRNA negatively regulating IL-6. Taken together, our results show that miR-365 is a novel negative regulator of IL-6.

Abstract
BACKGROUND Stromelysin (MMP-3) is an important regulator of vascular smooth muscle cell (SMC) invasion, a key contributor to saphenous vein (SV) bypass graft failure. The 5A allele of the common -1612 MMP-3 5A/6A promoter polymorphism reportedly confers increased promoter activity, MMP-3 tissue expression, and susceptibility to a number of vascular pathologies. The aim of this study was to determine whether the MMP-3 5A/6A polymorphism directly influences endogenous MMP-3 expression levels and, consequently, cell invasion, in SV-derived SMC cultured from patients with different genotypes. MATERIAL AND METHODS Genotyping of 226 patients revealed -1612 MMP-3 5A/6A genotype frequencies of 20.8% 5A/5A, 52.7% 5A/6A, and 26.5% 6A/6A. Using a standardized, controlled protocol, we investigated cytokine- and growth factor-induced MMP-3 expression (real-time polymerase chain reaction [RT-PCR], ELISA) and SV-SMC invasion (Boyden chamber with Matrigel barrier) using cultured SV-SMC from patients with different MMP-3 genotypes. RESULTS Despite observing a strong correlation between MMP-3 mRNA levels and MMP-3 protein secretion, no significant differences were apparent in MMP-3 expression levels or cell invasion between cells with different MMP-3 5A/6A genotypes. CONCLUSIONS Our data suggest that the MMP-3 5A/6A promoter polymorphism in isolation does not influence levels of MMP-3 secretion or cellular invasion in human SV-SMC.

Abstract
ZBP-89, a Krüppel-type zinc-finger transcription factor that binds to GC-rich sequences, is involved in the regulation of cell growth and cell death. It maps to chromosome 3q21 and is composed of 794 residues. Having bifunctional regulatory domains, ZBP-89 may function as a transcriptional activator or repressor of variety of genes such as p16 and vimentin. ZBP-89 arrests cell proliferation through its interactions with p53 and p21(waf1). It is able to stabilize p53 through directly binding and enhance p53 transcriptional activity by retaining it in the nucleus. In addition, ZBP-89 potentiates in butyrate-induced endogenous p21(waf1) up-regulation. ZBP-89 is usually over-expressed in human cancer cells, where it can efficiently induce apoptosis through p53-dependent and -independent mechanisms. Moreover, ZBP-89 is capable of enhancing killing effects of several anti-cancer drugs. Therefore, ZBP-89 may be served as a potential target in cancer therapy.

Abstract
CCL5 (previously called RANTES) was originally recognized as a product of activated T cells, and plays a crucial role in the migration and metastasis of human cancer cells. It has been reported that the effect of CCL5 is mediated via CCR receptors. We found that human chondrosarcoma tissues had significant expression of the CCL5 and CCR5, which was higher than that in normal cartilage. We also found CCL5 increased the migration and matrix metalloproteinases-3 (MMP)-3 expression in human chondrosarcoma cells (JJ012 cells). In addition, MMP-3 small interfering RNA and inhibitor inhibited the CCL5-induced cell migration. Activations of phosphatidylinositol 3-kinase (PI3K), Akt and NF-kappaB pathways after CCL5 treatment was demonstrated, and CCL5-induced expression of MMP-3 and migration activity was inhibited by the specific inhibitor of PI3K, Akt and NF-kappaB cascades. Taken together, these results indicate that CCL5 and CCR5 interaction enhanced migration of chondrosarcoma cells through the increase of MMP-3 production.
