Abstract EN
Background.
Soluble guanylyl cyclases (sGCs) and Ras homolog gene family, member A (rhoA)/Ras homolog gene family kinase(rho-kinase) plays a role in vascular smooth muscle relaxation in subarachnoid hemorrhage (SAH).
It is of interest to examine the effect of MLB on rhoA/ROCK and sGC/cGMP/PKG expression.
Methods.
A rodent SAH model was employed.
Tissue samples were for sGCα1, sGCβ1, PKG, rhoA, ROCK (Western blot), and cGMP (ELISA) measurement.
Results.
MLB morphologically improved convolution of the internal elastic lamina, distortion of endothelial wall, and necrosis of the smooth muscle in the SAH rats.
Expressed cGMP, sGCα1, sGCβ1, and PKG in the SAH groups were reduced (P<0.01), and MLB precondition significantly induced cGMP, sGCα1, sGCβ1, and PKG.
L-NAME reversed the vasodilation effect of MLB, reduced the bioexpression of PKG and cGMP (P<0.01), and tends to reduce sGCα1 level and induce rhoA, ROCK level in MLB precondition + SAH groups.
Conclusion.
These results demonstrate that sGC/cGMP/PKG and NO/ET pathways play pivotal roles in SAH-induced vasospasm.
Through activating sGC/cGMP/PKG pathway and partially by inactivating rho-kinase in a NO-dependent mechanism, MLB shows promise to be an effective strategy for the treatment of this disease entity.
