The Difference of ACE and ACE2 Gene Expression in Patients With Acute Aortic Dissection and Coronary Heart Disease
Abstract BackgroundTo explore whether there is a difference in the expression of ACE and ACE2 genes in patients with acute AD and CHD. MethodsBlood samples from 68 patients, including 34 cases of acute AD (including Stanford type A and B), 21 cases of CHD, and 13 cases of control group. 2 ml of venous blood is submitted for plasma ACE concentration. The arterial wall tissue was taken during the operation for mRNA detection. ResultsThe ACE concentration in the AD group was (17.9 ± 7. 9) U / L, in the CHD group was (33.5 ± 8.1) U / L, and the ACE concentration in the control group was (38.4) ±4.8) U/L, statistically significant (P<0.05). The expression of ACE gene in the AD group was (0.2265 ± 0.3783); the expression in the CHD group was (7.085 7 ± 7.692 9), with significant (P < 0. 05). The expression of ACE2 gene in the AD group was (0.766 2 ± 0.858 6); in the CHD group was (9.612 7 ± 11.542 6), and the difference was significant (P < 0. 05). The expression of the ratio of ACE / ACE2 in the AD group was (0.413 8 ± 0.448); the expression in the CHD group was (0.811 1 ± 0.256 3), the difference was statistically significant (P <0. 001). ConclusionPlasma ACE concentration, ACE and ACE2 gene expression are significantly reduced in acute AD. The imbalance of ACE and ACE2 expression may be involved in the pathogenesis of AD.
