Photodynamic therapy (PDT) involves the use of photochemical reactions mediated through the interaction of photosensitizing agents, light and oxygen to destroy abnormal tissue. The transfer of energy from the activated photosensitizer to available oxygen results in the formation of toxic reactive oxygen species, such as singlet oxygen and free radicals,(More)
Photodynamic therapy (PDT) is a local cancer treatment which induces cell death by the interaction of light with a photosensitizing drug. Previous studies indicate that nitric oxide (NO) plays a role in Photofrin-PDT, but this has not been investigated in aminolaevulinic acid (ALA)-PDT. The current study determines whether inhibition of nitric oxide(More)
It has been suggested that metastasis-initiating cells gain a foothold in bone by homing to a metastastatic microenvironment (or "niche"). Whereas the precise nature of this niche remains to be established, it is likely to contain bone cell populations including osteoblasts and osteoclasts. In the mouse tibia, the distribution of osteoblasts on endocortical(More)
Mammography is an important screening modality for the early detection of DCIS and breast cancer lesions. More specifically, high mammographic density is associated with an increased risk of breast cancer. However, the biological processes underlying this phenomenon remain largely unknown. Here, we re-interrogated genome-wide transcriptional profiling data(More)
BACKGROUND While both preclinical and clinical studies suggest that the frequency of growing skeletal metastases is elevated in individuals with higher bone turnover, it is unclear whether this is a result of increased numbers of tumour cells arriving in active sites or of higher numbers of tumour cells being induced to divide by the bone micro-environment.(More)
In vascular smooth muscle cells (VSMCs) integrin-mediated adhesion to extracellular matrix (ECM) proteins play important roles in sustaining vascular tone and resistance. The main goal of this study was to determine whether VSMCs adhesion to type I collagen (COL-I) was altered in parallel with the changes in the VSMCs contractile state induced by(More)
AIMS The lack of understanding of the biology of bone cancer metastasis has limited the development of effective treatment strategies. The aim of this study was to characterize tumor cell adhesion molecules and determine active tumor cell interactions with human bone marrow endothelial (BME) cells using atomic force microscopy. MATERIALS & METHODS A(More)
Micrometastasis is a barrier to the development of effective cancer therapies for prostate cancer metastasis to bone. The mechanisms remain incompletely characterised, primarily due to an inability to adequately monitor the initial metastatic events in vivo. This study aimed to establish a new model, allowing the tracking of prostate cancer cells homing to(More)
This study evaluated four fluorescent-protein conjugates to monitor microcirculatory variables using the murine cremaster muscle and determined acute and long-term responses to repeated administration of FITC-BSA [conjugated at the University of Sheffield (UoS)] within a dorsal microcirculatory chamber (DMC) in rats. For analysis of the cremaster muscle,(More)
