Abstract
Objectives: To assess the messenger ribonucleic acid expression in placental tissue of growth factors, cytokines, angiogenic and anti-angiogenic factors in one case of recurrent multiple chorioangiomas. Methods: Complementary deoxyribonucleic acid array analysis was performed on the affected placentae and on normal placentaes (controls) to compare messenger ribonucleic acid levels of 96 genes involved in angiogenesis. Results: Eleven genes presented more than two-fold alteration in expression levels: undetectable (angiopoietin 1, osteonectin, tyrosine kinase endothelial, neuropilin 1), decreased (transcription growth factor β receptor 3, tissue inhibitor of metalloproteinase type 2, EGF receptor, integrin-α V, tyrosine kinase vascular endothelial growth factor receptor 2), increased (angiopoietin 2, osteopontin). Conclusions: We illustrated the complexity of angiogenic disruption in recurrent multiple chorioangiomas leading to the difficulty to propose a single candidate gene to explain this pathology.
