Project description:Analysis of the effects of cell shape on human coronary artery endothelial cell transcription. The hypothesis is that defined alterations in endothelial cell shape uniquely affect the endothelial transcriptome. Human coronary artery endothelial cells were plated onto spatially defined micropatterns (Cytoo) forcing them to conform to Disc, Crossbow, H, Y, or L shapes. As a control, human coronary artery endothelial cells were plated on non-restrictive areas of the Cytoo growth plate.

As a control, human coronary artery endothelial cells were plated on non-restrictive areas of the Cytoo growth plate. RNA was collected after 24 hours growth on the restricted or non-restricted growth patterns and subjected to whole genome microarray analysis.
Project description:We quantified differential microRNA (miRNA) expression on human HDL before and after incubation with human coronary artery endothelial cells. These data were used to determine which miRNAs are altered on HDL (taken up or effluxed to) by human coronary artery endothelial cells.
Project description:Currently, it is well established that human endothelial cells (ECs) are characterised by a significant heterogeneity between distinct blood vessels, e.g., arteries, veins, capillaries, and lymphatic vessels. Further, even ECs belonging to the same lineage but grown under different flow patterns (e.g., laminar and oscillatory or turbulent flow) ostensibly have distinct molecular profiles defining their physiological behaviour. Human coronary artery endothelial cells (HCAEC) and human internal thoracic artery endothelial cells (HITAEC) represent two cell lines inhabiting atheroprone and atheroresistant blood vessels (coronary artery and internal thoracic artery, respectively). Resistance of the internal mammary artery to atherosclerosis has been largely attributed to the protective phenotype of HITAEC which reportedly produce higher amounts of vasodilators including nitric oxide (NO) through the respective signaling pathways. However, this hypothesis has not been adequately addressed hitherto as proteomic profiling of HCAEC and HITAEC in a head-to-head comparison setting has not been performed.

These data were used to determine which miRNAs are altered on HDL (taken up or effluxed to) by human coronary artery endothelial cells. Each group had a n=4 and HDL-miRNA levels post incubations were compared to pre incubations with cells.
