    RhoA and ROCK2 upregulation in the rat hippocampus is involved in memory dysfunction induced by postnatal exposure of Sevoflurane. The expression of RhoA, ROCK2 and cleaved caspase-3 (Cl-Csp3) in the hippocampus of the S3 group significantly increased, compared to that of the C group (P<0.05). There is no difference of the level of RhoA, ROCK2 and Cl-Csp3 between the C and S1 groups (P>0.05). ROCK2 inhibitor Fasudil hydrochloride in the F group clearly decreases the expression of ROCK2 and Cl-Cs

    Cells lysates are subjected to SDS-PAGE and immunoblotted with anti-phospho-Akt (Ser473) and total Akt antibodies. PPARγ is used as a differentiation marker, and β-tubulin and α-actin as loading controls.

    In Vitro

    Fasudil has vasodilatory action and occupies the adenine pocket of the ATP-binding site of the enzyme[1]. Fasudil produces a competitive inhibition of the Ca2+-induced contraction of the depolarized rabbit aorta. Fasudil inhibits contractile responses to KCl, phenylephnne (PHE) and prostaglandin (PG) F2a[2]. Fasudil also exhibits vasodilator actions by inhibition of 5-hydroxytryptamine, noradrenaline, histamine, angiotensin, and dopamine induced spiral strips contraction[3]. In addition, Fasudil induces disorganization of actin stress fiber and cell migration inhibition[4]. Fasudil inhibits hepatic stellate cells spreading, the formation of stress fibers, and expression of α-SMA with concomitant suppression of cell growth, but does not induce apoptosis. Fasudil also blocks the LPA-induced phosphorylation of ERK1/2, JNK and p38 MAPK[5].

    In Vivo

    Fasudil (30 μg) increases CBF by 50% via intra-coronary injection to dogs. Fasudil (0.01, 0.03, 0.1 and 0.3 mg/kg, bolus, i.v.) decreases MBP and increases HR, VBF, CBF, RBF, and FBF. Fasudil (1.0 ng/mL) increases cardiac output. Fasudil via i.v. produces a significant fall in MBP, left ventricular systolic pressure and total peripheral resistance with an increase in HR and cardiac output, but without obvious effect on right atrial pressure, dP/dt or left ventricular minute work in dogs[3]. Fasudil exhibits protectable effects on cardiovascular disease and reduces the activation of JNK and attenuates mitochondrial-nuclear translocation of AIF under ischemic injury[6]. Fasudil (100 mg/kg/day, p.o.) significantly reduces incidence and mean maximum clinical score of EAE in SJL/J mice immunized with PLP p139-151. Fasudil inhibits the proliferative response of splenocytes to the antigen in mice. Fasudil decreases inflammation, demyelination, axonal loss and APP positivein spinal cord of Fasudil-treated mice via p.o. administration[7].

    Kinase Assay

    Cyclic AMP-dependent protein kinase activity is assayed in a reaction mixture containing, in a final volume of 0.2 mL, 50 mM Tris-HCl (pH 7.0), 10 mM magnesium acetate, 2 mM EGTA, 1 μM cyclic AMP or absence of cyclic AMP, 3.3 to 20 μM [r-32P] ATP (4×105 c.p.m.), 0.5 μg of the enzyme, 100 μg of histone H2B and compound. The mixture is incubated at 30°C for 5 min. The reaction is terminated by adding 1mL of ice-cold 20% trichloroacetic acid after adding 500 μg of bovine serum albumin as a carrier protein. The sample is centrifuged at 3000 r.p.m. for 15min, the pellet is resuspended in ice-cold 10% trichloro-acetic acid solution and the centrifugation-resuspension cycle is repeated three times. The final pellet is dissolved in 1 mL of 1 N NaOH and radioactivity is measured with a liquid scintillation counter[1].
