Investigating pathways in tumour cell migration and invasion in response to novel isoquinolinone compounds
Abstract The ability of cancer cells to disseminate from a primary tumour and invade via the breaching of surrounding tissue vasculature is a hallmark of the metastatic phenotype. Cancer cells are highly dynamic adopting a wide range of mechanisms in order to accomplish this enhanced migrational …

The Effects of Acetylenic Tricyclic Bis-(Cyano Enone) on Cell Migration
… small pharmacological compounds to inhibit tumour cell motility, as a strategy against tumour cell migration, invasion, and metastasis. The acetylenic tricyclic bis-(cyano enone), TBE-31, has been shown to be a promising chemopreventative compound. However, its effects on cell migration are …

Correlation between the expression of integrins and their role in cancer progression. Expression pattern of integrins αvβ3, αvβ5 and α5β1 in clinical and experimental tumour samples
The integrins play a crucial role in cancer cell proliferation, migration, differentiation, survival and angiogenesis. It has been shown that integrin expression is positively correlated to cancer dissemination, this suggests targeting selected integrins as an anti-metastatic strategy. The aim of …

Design, Synthesis and Biological Evaluation of Inhibitors of Polysialyltransferases PST and STX. Design, synthesis and biological evaluation of a range of N-modified mannosamines, sialic acids and analogues from in silico screening as inhibitors of PolySia-NCAM biosynthesis with anti-migration activity.
… (polySia-NCAM) is re-expressed in a number of tumours, including small cell lung carcinoma and neuroblastoma and is strongly associated with aggressive, invasive and metastatic tumours in the clinic. SiRNA knockdown of the polysialyltransferases (polySTs), the enzymes responsible for …

Synthesis of inhibitors of polysialyltransferases PST and STX. Development of routes to synthesis, preparation and purification of carbohydrate and carbacycle-based potential inhibitors of the polysialyltransferase enzymes PST and STX
… a posttranslational modification of NCAM (neural cell adhesion molecule), biosynthesized by combined action of two polysialyltransferase enzymes, ST8SiaIV(PST) and ST8SiaII(STX). PolySia alters NCAM-dependent cell adhesion that is crucial for the CNS development. In adulthood, polySia expression …

Targeting c-Met for therapy
… such as motility, angiogenesis, morphogenesis, cell survival and cell regeneration. c-Met and HGF knock-out mice are embryonic lethal. During embryogenesis, c-Met is required for liver, kidney and skeletal muscles development. In adult tissues, c-Met is involved in wound healing and hepatocyte …

The role of DNA damage associated microRNAs in enhancing the chemotherapeutic responses in triple negative breast cancer (TNBC)
… is a heterogeneous aggressive type of mammary tumour which lacks a definite tailored therapeutic approach, consequently limiting treatment options to chemotherapeutic agents. Doxorubicin has demonstrated significant efficacy in the treatment of TNBC although many patients experience recurrent …

Recapitulating mammary gland development and breast cancer cell migration in vitro using 3D engineered scaffolds
… epithelium of luminal and myoepithelial cells surrounded by an adipocyte-rich fat pad, a highly collagenous extra-cellular matrix (ECM) and a number of other stromal and endothelial cell types. Mammary stem cells (MaSCs) reside within the epithelium and these are capable of repopulating a …

The expression and role of Migration Stimulating Factor (MSF) in oral tumours
Migration Stimulating Factor (MSF) is an oncofoetal protein which is constitutively produced by both epithelial and stromal cells during foetal development, not expressed by the majority of their normal adult counterparts, but re-expressed during pathological processes such as cancer and wound …

Funktionelle Untersuchungen zum Einfluss von FAP-Inhibitoren auf die Tumorzellmigration und Invasion
… fuehrte zu einer subtotalen Inhibition der Zellmigration (Zeitraffervideomikroskopie und Zelltracking). Die Inhibition der Motilitaet war nicht toxisch, dosisabhaengig, spezifisch für FAP-exprimierende Zellen und in der gesamten Zellpopulation nachweisbar. Die Inhibition von FAP fuehrte darueber …

An immunohistopathological and functional investigation of β3 integrin antagonism as a therapeutic strategy in cancer. Characterisation, development, and utilisation of preclinical cancer models to investigate novel ¿3 integrin anatgonists.
Tumour cell dissemination is a major issue with the treatment of cancer, thus new therapeutic strategies which can control this process are needed. Antagonism of integrins highly expressed in tumours is one potential strategy. The integrins are transmembrane glycoprotein adhesive receptors. Two of …
