Abstract:
Academic: Ovarian cancer is the leading cause of death among female gynecologic cancers. Current treatments include surgical debulking, and chemotherapy. However, better interventions are needed to reduce the mortality rate of metastatic disease. Ovarian cancer cells have displayed the ability to aggregate and form 3D homogeneous and heterogeneous spheroids, which can function as micrometastases. Ovarian cancer spheroids survive independently prior to adhering to an endothelial tissue. Since aggregation has been shown to provide a survival advantage to the spheroids and increased their aggres

Abstract:
Matrix metalloproteinases (MMPs) are a family of zinc endopeptidases capable of digesting the extracellular matrix (ECM), which is essential for tissue structure and transmitting messages between cells. MMPs play an important role in cancer, controlling cell migration, proliferation, apoptosis, regulation of tumour expansion, angiogenesis and invasion. Previous research has indicated high expression of MT1-MMP in breast cancers suggesting a potential role in tumour progression.

Abstract:
High-throughput drug screening (HTS) in live cells is often a vital part of the preclinical anticancer drug discovery process. So far, two-dimensional (2D) monolayer cell cultures have been the most prevalent model in HTS endeavors. However, 2D cell cultures often fail to recapitulate the complex microenvironments of in vivo tumors. Monolayer cultures are highly proliferative and generally do not contain quiescent cells, thought to be one of the main reasons for the anticancer therapy failure in clinic. Thus, there is a need for in vitro cellular models that would increase predictive value of

The ultimate challenge lies in replicating the native cell/tissue environment ex vivo. Certain key features of living tissues such as the three dimensionality, biophysical and biochemical microenvironment cannot be readily replicated in traditional cult

Abstract:
This work presents an alternative approach to the production of cellulose-based biomaterials. Instead of extracting, processing and regenerating plant and or bacteria-derived cellulose into a biomaterial, my work established a decellularization protocol to remove cellular plant content from plant tissue resulting in a scaffold composed of cellulose with the evolved architecture of the plant cell wall. Tracheophyte plants, including clubmosses, horsetails, and ferns, gymnosperms and angiosperms, have evolved distinct vascular structures that support the transport of water and nutrients in xyle

Abstract:
In pharmaceutical development cell cultures are used as in vitro models to evaluate the function of drug candidates. In such research it is vital to have models that resemble the in vivo environment to get reliable results. In 3D models with hydrogels ECM like scaffolds are supporting the cells in a more in vivo like environment than flat 2D cultures. In this project PEG-peptide based hydrogels with cell binding RGD incorporated on one PEG-peptide type has been evaluated for culturing of HepG2 cells. Structure and viscoelastic properties were evaluated with techniques like circular dichroism s

Abstract:
LKB1 is the second most commonly altered tumour suppressor gene in lung adenocarcinoma, the most prevalent form of lung cancer. LKB1 is a "master kinase" that has been shown to phosphorylate up to 13 downstream targets. We hypothesised that LKB1 loss is associated with an increased dependency on alternative, targetable pathways. The overall aims of this project were to better understand the role of LKB1 loss in lung cancer and to identify novel approaches to selectively target LKB1 mutated cells. We generated isogenic cells with or without LKB1 and used these to study the effect of LKB1 on cel

Abstract:
Engineering self-organised spatial patterns based on reaction-diffusion models can be the stepping stone for tissue engineering. Previous reports based on both theoretical and experimental studies have implied the importance of ultrasensitivity and differential diffusion as key requirements for building self-organised spatial patterns on mammalian cells with extracellular signalling systems. In the sender-receiver system developed by our team using Madin-Darby canine kidney (MDCK) cysts and hepatocyte growth factor (HGF) signalling, I have explored the sensitivity of different genes to varying
