Research Abstract |
Enhanced accumulation of the modified glucose analogue 18fluoro-deoxyglucose by positron emission tomography imaging in the human abdominal aortic aneurysm (AAA) was associated with protein expressions of glucose transporters-1 and -3, assessed by Western blot. The magnitude of glucose transporter-3 expression was correlated with matrix metalloproteinase (MMP)-9 activity, co-localized in macrophages of the aneurysmal wall. In monocytic cell line induced by phorbol 12-myristate 13-acetate, the inhibition of glucose transport or glycolysis abrogated the MMP-9 activity in these cells. Furthermore, the inhibition of glycolysis activity with the intra-peritoneal administration of 2-deoxyglucose significantly attenuated the dilatation of abdominal aorta induced by periaortic application of calcium chloride in C57BL/6J male mice or reduced the aneurysmal formation in angiotensin II-infused apolipoprotein E knockout male mice.
