Objective: Resident macrophages play an important role in atheromatous plaque rupture. The macrophage gene expression signature associated with plaque rupture is incompletely defined due to the complex cellular heterogeneity in the plaque. We aimed to characterise differential gene expression in resident plaque macrophages from ruptured and stable human atheromatous lesions. A cell-specific approach has the potential to address the question of gene expression differences between particular cell types in stable and unstable plaques with greater precision than approaches based on the study of whole plaques. Using laser micro-dissection, we isolated total RNA from macrophage-rich regions of stable and ruptured human atheromatous plaques derived from carotid endarterectomy samples which were comprehensively characterized using clinical, radiological and histological criteria, and carried out genome-wide gene expression profiling using microarrays.
Increased expression of fatty acid binding protein 4 and leptin in resident macrophages characterises atherosclerotic plaque rupture.

View SamplesTriple negative breast cancer (TNBC) is the most aggressive breast cancer subtype with the worst prognosis. It is characterised by the absence of hormone receptors for estrogen, progesterone, and human epidermal growth factor 2, and as a consequence there are no targeted endocrine treatments available. TNBC patients are more likely to develop metastases and disease relapse than patients with other breast cancer subtypes. The identification of biomarkers that can be used to predict which patient is likely to develop metastatic disease remains a priority since this is the major cause of cancer-related death in these women.

View SamplesAcrylamide is a reproductive toxicant that has been detected in foods such as potato chips and breads. The consequences of chronic exposure to acrylamide in the human diet are unknown; however we previously reported that exposure to acrylamide at levels equivalent to human exposure produced high levels of genetic damage in early male germ cells of mice [Nixon et al. ToxSci 129(1), 135145 (2012)]. In the present study, we examined changes in testicular gene expression in these mice to examine the potential mechanisms involved in acrylamide induced DNA damage in male germ cells and to provide a better understanding of the reproductive toxic effects of acrylamide in the male.
