Abstract
Glioblastoma multiforme (GBM) is the deadliest and the most common primary malignant brain tumour. The median survival for patients with GBM is around one year due to the nature of glioma cells to diffusely invade that make the complete surgical resection of tumours difficult. Based upon the connexin43 (Cx43) model of glioma migration we have developed a computational framework to evaluate MMP inhibition in materials relevant to GBM. Using the ilomastat Leu-Trp backbone, we have synthesised novel sulphonamides and monitored the performance of these compounds in conditioned media expressing MMP3. From the results discussed herein we demonstrate the performance of sulfonamide based MMPIs included AP-3, AP-6, and AP-7.

Abstract
Matrix metalloproteinases are zinc-dependent enzymes whose main function is to cleave the components of the extracellular matrix. Their overexpression is evident in all cancers but to date there is no satisfactory way to inhibit their actions. Here, we look at their types, their structures, their functions and the developing understanding we have of them in the search for ways to drug them and inhibit their actions selectively. We investigate their subtle but exploitable differences in order that we can develop drugs to target them and even to target specific substrates and functions that they carry out. To date there are no new matrix metalloproteinase inhibitors developed to treat cancer, but we are progressing in our understanding of them, which is leading us ever closer to our goal.

Abstract
This study sought to devise a way to assess the infiltration of cancer cells in model stromal tissues. Human breast carcinoma MDA-MB-231 cells were loaded on the surface of a type I collagen gel in the well of 8-well chamber slide and allowed to migrate into the gel. The gel was then subjected to frozen sectioning and staining. Azan staining facilitated satisfactory microscopic observation of cancer cells migrating into the collagen gel. Cell migration was promoted by the presence of fetal calf serum in the gel. In contrast, the proportion of cells remaining on the gel surface increased in the presence of galardin, a matrix metalloproteinase inhibitor. Moreover, the distance of cell migration from the gel surface was significantly shorter depending on the concentration of galardin. Observation of cancer cell migration into reconstituted type I collagen gel with a combination of frozen sectioning and azan staining is a useful way to assess the ability of individual cancer cells to migrate and to evaluate how effectively pharmaceuticals inhibit the first step of invasion.

Abstract
Stimulation of α1aAdrenergic Receptors (ARs) is known to have anti-proliferative and hypertrophic effects; however, some studies also suggests this receptor can increase cell proliferation. Surprisingly, we find the α1aAR expressed in rat-1 fibroblasts can produce either phenotype, depending exclusively on agonist concentration. Stimulation of the α1aAR by high dose phenylephrine (>10−7 M) induces an antiproliferative, hypertrophic response accompanied by robust and extended p38 activation. Inhibition of p38 with SB203580 prevented the antiproliferative response, while inhibition of Erk or Jnk had no effect. In stark contrast, stimulation of the α1aAR with low dose phenylephrine (∼10−8 M) induced an Erk-dependent increase in cellular proliferation. Agonist-induced Erk phosphorylation was preceded by rapid FGFR and EGFR transactivation; however, only EGFR inhibition blocked Erk activation and proliferation. The general matrix metalloprotease inhibitor, GM6001, blocked agonist induced Erk activation within seconds, strongly suggesting EGFR activation involved extracellular triple membrane pass signaling. Erk activation required little Ca2+ release and was blocked by PLCβ or PKC inhibition but not by intracellular Ca2+ chelation, suggesting Ca2+ independent activation of novel PKC isoforms. In contrast, Ca2+ release was essential for PI3K/Akt activation, which was acutely maximal at non-proliferative doses of agonist. Remarkably, our data suggests EGFR transactivation leading to Erk induced proliferation has the lowest activation threshold of any α1aAR response. The ability of α1aARs to induce proliferation are discussed in light of evidence suggesting antagonistic growth responses reflect native α1aAR function.

Abstract
The human matrix metalloprotease 9 (hMMP-9) is involved in many physiological processes such as tissue remodeling. Its overexpression in tumors promotes the release of cancer cells thus contributing to tumor metastasis. It is a relevant marker of malignant tumors. We selected an RNA aptamer containing 2'-fluoro, pyrimidine ribonucleosides, that exhibits a strong affinity for hMMP-9 (K(d) = 20 nM) and that discriminates other human MMPs: no binding was detected to either hMMP-2 or -7. Investigating the binding properties of different MMP-9 aptamer variants by surface plasmon resonance allowed the determination of recognition elements. As a result, a truncated aptamer, 36 nucleotides long, was made fully resistant to nuclease following the substitution of every purine ribonucleoside residue by 2'-O-methyl analogues and was conjugated to S-acetylmercaptoacetyltriglycine for imaging purposes. The resulting modified aptamer retained the binding properties of the originally selected sequence. Following (99m)Tc labeling, this aptamer was used for ex vivo imaging slices of human brain tumors. We were able to specifically detect the presence of hMMP-9 in such tissues.

Abstract
Degradation of elastin, the main amorphous component of elastic fibers, by elastases belonging to the serine, metallo, or cysteine families leads to the generation of elastin fragments, designated as elastokines in keeping with their cytokine-like properties. Generation of elastokines from one of the longest lived protein in human might represent a strong tissue repair signal. Indeed, they (1) exhibit potent chemotactic activity for leukocytes, (2) stimulate fibroblast and smooth muscle cell proliferation, and (3) display proangiogenic activity as potent as VEGF. However, continuous exposure of cells to these matrikines, through increased elastase(s) expression with age, can contribute to the formation of a chronic inflammatory state, that is, inflamm-aging. Importantly, binding of elastokines to S-Gal, their cognate receptor, proved to stimulate matrix metalloproteinase expression in normal and cancer cells. Besides, these elastin fragments can polarize lymphocytes toward a Th-1 response or induce an osteogenic response in smooth muscle cells, and arterial wall calcification. In this chapter, emphasis will be made on the contribution of elastokines on the genesis of age-related arterial wall diseases, particularly abdominal aortic aneurysms (AAAs). An elastokine theory of AAAs progression will be proposed. Age is one main risk factor of cancer incidence and development. The myriad of biological effects exerted by elastokines on stromal and inflammatory cells led us to hypothesize that they might be main actors in elaborating a favorable cancerization field in melanoma; for instance these peptides could catalyze the vertical growth phase transition in melanoma through increased expression of gelatinase A and membrane-type 1 matrix metalloproteinase.

Abstract
Botulinum neurotoxins (BoNTs A-G) are zinc metalloendoproteases that exhibit extraordinary specificities for proteins involved in neurotransmitter release. In view of the extreme toxicities of these molecules, their applications in human medicine, and potential for misuse, it is of considerable importance to elucidate the mechanisms underlying substrate recognition and to develop inhibitors, with the ultimate goal of obtaining anti-botulinum drugs. We synthesized peptides based on vesicle-associated membrane protein (VAMP) to investigate the substrate requirements of BoNT F, which cleaves VAMP between residues Q58 and K59. The minimum substrate was a peptide containing VAMP residues 32-65, which includes only one of the two VAMP structural motifs thought to be required for botulinum substrate recognition. BoNT F exhibited a strict requirement for residues D57 (P(2)), K59 (P(1)'), and L60 (P(2)'), but peptides containing substitutions for R56 (P(3)), Q58 (P(1)), and S61 (P(3)') were cleaved. Therefore, the P(2), P(1)', and P(2)' residues of VAMP are of paramount importance for BoNT F substrate recognition near the scissile bond. K(i) values of uncleavable analogues were similar to K(m) values of the substrate, suggesting that substrate discrimination occurs at the cleavage step, not at the initial binding step. We then synthesized inhibitors of BoNT F that incorporated d-cysteine in place of glutamine 58, exhibited K(i) values of 1-2 nM, and required binding groups on the N-terminal but not the C-terminal side of the zinc ligand. The latter characteristic distinguishes BoNT F from other zinc metalloendoproteases, including BoNTs A and B.
