Microcirculatory disturbances contribute to the expansion of infarct lesions after focal cerebral ischemia. Recently, it was shown that Rho-kinase involves in endothelial dysfunction via down-regulation of endothelial nitric oxide synthase function in a rodent stroke model. However, it is not clear whether endothelial Rho-kinase is activated in vivo or Rho-kinase activation contributes to microcirculatory disturbances after cerebral ischemia. In this study, we assessed the temporal and spatial profiles of Rho-kianse activity and the effect of the Rho-kinase inhibitor fasudil on microcirculatory disturbances in the focal brain ischemia. Rho-kinase activation was evaluated by analyzing the phosphorylation of adducin, a substrate of Rho-kinase, by immunohistochemistry. Staining for p-adducin was found in endothelia in the ischemic area 6 hr after induction of ischemia. Microcirculatory disturbances and increased endothelial cell staining for von Willebrand factor (vWF) were observed in the same ...
Among the GTP-binding proteins, Rho is known to function as a molecular switch in various cellular functions. Among the Rho effectors, the cellular function and signal transduction of Rho-kinase have been extensively studied. However, information about its in vivo functions is still limited. With the recent development of a specific Rho-kinase inhibitor such as Y-27632 and fasudil, the understanding of the role of the Rho/Rho-kinase pathway in vitro and in vivo has advanced. However, to date, there have been few studies investigating the role of Rho-kinase in renal disease. Recent studies have shown that Rho-kinase inhibitor significantly attenuated the tubulointerstitial fibrosis in kidney induced by unilateral ureteral obstruction. However, there have been few studies investigating the role of the Rho/Rho-kinase pathway in hypertensive glomerular sclerosis. In this review, we described the role of the Rho/Rho-kinase pathway in the progression of renal glomerulosclerosis in several forms of ...
Title:Rho Kinase Inhibitors: Potential Treatments for Diabetes and Diabetic Complications. VOLUME: 18 ISSUE: 20. Author(s):Hong Zhou and Yong-jun Li. Affiliation:Department of Cardiology, The Second Hospital of Hebei Medical University, Shijiazhuang 050000, China.. Keywords:RhoA, Rho kinase, inhibitors, diabetes, complications, GTPase, hypertension, coronary vasospasm, stroke, atherosclerosis. Abstract:The small GTPase RhoA and its downstream effector, Rho kinase (ROCK), appear to mediate numerous pathophysiological signals, including smooth muscle cell contraction, actin cytoskeleton organization, cell adhesion and motility, proliferation, differentiation and the expression of several genes. Clinical interest in the RhoA/ROCK pathway has increased, due to emerging evidence that this signaling pathway is involved in the pathogenesis of several diseases, including hypertension, coronary vasospasm, stroke, atherosclerosis, heart failure and diabetes; ROCK is considered an important future ...
The current study demonstrates that in secondary biliary cirrhosis (1) Rho-kinase activation is substantially involved in the defective eNOS signaling; (2) Rho-kinase may directly interact with Akt and subsequently inhibit Akt-eNOS signaling; and (3) the intravenous infusion of a regular dose of fasudil (1 mg/kg/hour), a specific inhibitor of Rho-kinase, significantly decreases PVP without reducing HTBF through the up-regulation of eNOS.. Liver cirrhosis is associated with increased intrahepatic vascular resistance leading to portal hypertension. HSC contractility, which is regulated by the balance between vasoconstricting agents such as endothelin-1 and vasorelaxing agents such as NO, contributes to increased intrahepatic vascular resistance. HSCs are also a major source of extracellular matrix in liver cirrhosis, and their activation increases hepatic fibrosis, resulting in increased intrahepatic vascular resistance. Rho-kinase, a downstream effector of GTPase Rho, has been shown to be ...

The addition of both MEK1 inhibitor U0126 or JNK inhibitor SP600125 coupled with RI inhibitor SB431542 had no detectable result to the mesenchymal phenotype on the cells. The mixture these details of p38 MAPK inhibitor SB203580 and ROCK inhibitor Y27632 restored cortical actin stain ing, but tension fiber actin remained inside the cells. Escalating the concentration of RI inhibitor SB431542 to ten M led to a even more lessen from the level of anxiety fib ers, nonetheless, the combination of RI inhibitor SB431542 by using a p38 MAPK inhibitor SB203580 or ROCK inhibitor Y27632 was additional effective at getting rid of them.

ROCK (Rho-associated protein kinase) is a kinase belonging to the AGC (PKA/ PKG/PKC) family of serine-threonine kinases. ROCKs (ROCK1 and ROCK2) occur in mammals, zebrafish, Xenopus, invertebrates and chicken. Human ROCK1 has a molecular mass of 158 kDa and is a major downstream effector of the small GTPase RhoA. Mammalian ROCK consists of a kinase domain, acoiled-coil region and a Pleckstrin homology (PH) domain, which reduces the kinase activity of ROCKs by an autoinhibitory intramolecular fold if RhoA-GTP is not present. ROCK plays a role in a wide range of different cellular phenomena, as ROCK is a downstream effector protein of the small GTPase Rho, which is one of the major regulators of the cytoskeleton.. ...

Rho family GTPases have received increasing attention as critical regulators of cell function (1). Initially, they were shown to regulate actin dynamics, thereby modulating development, cell migration, immune responses, and cancer cell invasion and metastasis. More recent studies have shown that they are also involved in cell-cell adhesion and cell cycle progression. RhoA is one of the most widely studied of the 22 mammalian members of the family, and the serine-threonine kinase Rho kinase (ROCK) is a major RhoA effector.. RhoA/ROCK has a number of functions in the kidney. RhoA/ROCK enhances Ca2+-dependent vascular smooth muscle contraction, thereby modulating tone (2-4). The potent vasoconstrictor angiotensin II (AngII) activates ROCK in smooth muscle cells. The ROCK inhibitors fasudil and Y-27632 dilate afferent and efferent arterioles and reverse AngII-dependent arteriolar vasoconstriction. At the cellular level, RhoA/ROCK mediates cytoskeletal rearrangement in renal tubule cells, mesangial ...

Excitotoxic cell death, the end for many cells after ischemic brain injury and in some neurodegenerative diseases, is triggered by glutamate-induced calcium influx. Downstream, activation of the p38α map kinase leads to apoptosis, but just how calcium and p38 connect has been an open question. New results from Michael Courtneys lab at the University of Kuopio in Finland show that the small GTPase Rho is the missing link. Their work, published in the March 18 online edition of Nature Neuroscience, establishes Rho activation by calcium influx as a necessary and sufficient event to turn on p38 and cause cell death in primary neurons.. Their results open up a potential new target for drugs to block excitotoxicity, and may have some additional relevance to Alzheimer disease. Inhibitors of Rho and its downstream kinase Rock can modulate amyloid-β (Aβ) peptide production (Zhou et al., 2003; Leuchtenberger et al., 2006). In addition, Rho is farnesylated, and changes in Rho/Rock pathway activity have ...

p116Rip targets myosin phosphatase to the actin cytoskeleton and is essential for RhoA/ROCK-regulated neuritogenesis.: Activation of the RhoA-Rho kinase (ROCK)
This antibody is designed, produced, and validated as part of a collaboration between Rockland and the National Cancer Institute (NCI) and is suitable for Cancer, Immunology and Nuclear Signaling research. Progression of tumors to invasive and metastatic forms requires that tumor cells undergo dramatic morphological changes, a process regulated by Rho GTPases. Increased levels of RhoA or RhoC, as well as the Rho effector proteins ROCK-1 or ROCK-2, were observed in various human carcinomas. In vivo studies have also shown that ROCK inhibition reduced the invasiveness of several tumor cell lines. It is suggested that Rho and ROCK signaling contribute to the morphological changes and metastatic behavior of some tumor cells. Thus, elevated Rho and ROCK expression is associated with tumorigenesis, particularly during the progression to invasive and metastatic phenotypes. Phosphorylation of certain residues in ROCK-2 may be critical for its kinase activity.
Rho-kinase II (ROCK-II) is a serine/threonine kinase that is involved in regulation of smooth muscle contraction and has been shown to contribute to the early stages of axon formation in neurons and the regulation of the neuronal cytoskeleton. Much of what is known about Rho-kinase function comes from cell-biological studies, whereas a paucity of biochemical characterization exists for the enzyme. In an effort to characterize ROCK-II biochemically we have cloned a truncated form of human ROCK-II comprising amino acids 1-543 and overexpressed it in Sf-21 cells. Utilizing the Sf-21/baculovirus expression system we isolated milligram quantities of ROCK-II (1-543) and purified the enzyme to near homogeneity. Optimal expression conditions revealed that infection of Sf-21 cells at a multiplicity of infection of 10 for 72h yielded maximal protein expression. Expression of ROCK-II (1-543) as an N-terminal Flag fusion protein allowed a single-step purification yielding greater than 90% homogeneous ...

Although human, rat, and mouse K2P6.1s have been cloned and the electrophysiological properties studied in heterologous expression systems,4,5,17 the physiological function of K2P6.1 is presently not known. The fact that K2P6.1 is highly expressed in all of the blood vessels studied to date2,7-10 led us to ask questions regarding the functional role of K2P6.1 in the vascular system. Our studies reveal the following: (1) K2P6.1 influences systemic blood pressure; (2) K2P6.1 regulates the contractile state of vascular muscle, likely by setting its membrane potential and rho kinase activity; and (3) K2P6.1 does not appear to be involved with VSMC migration, proliferation, or volume regulation in the models tested.. We acknowledge the inherent limitations in the use of a mouse KO model, because pretranslational or posttranslational changes in other genes can occur with gene deletion, especially when the gene deletion leads to pathophysiological conditions, such as hypertension. Further studies into ...
The direct regulation of Rho/Rho-kinase by miR-21 augments our evolving understanding of this pathway in the diseased pulmonary vasculature. Upregulation of RhoA is known to induce Rho-kinase activity, leading to pulmonary vascular pathology.28 Less is known about the functions of RhoB in the vasculature, although, in cell culture, it suppresses angiogenesis41 and can induce a vasoconstrictive phenotype by activating endothelin-142 and repressing endothelial nitric oxide synthase.31 Thus, our findings emphasize the underappreciated importance of RhoB in control of the dysregulated pulmonary vessel.. Furthermore, integration of various PH-relevant stimuli by miR-21 correlates with the known pleiotropic activity of this miRNA in various pathological contexts (as reviewed in Reference 39). Although modulation of RhoB reflects an important function of miR-21, other direct targets of miR-21 may affect downstream PH development. Among these, BMPRII may represent a key target given its role in PH ...

AU - Caldwell, R. B.. AU - Caldwell, R. William. PY - 2012/1/1. Y1 - 2012/1/1. N2 - Background and Purpose NO produced by endothelial NOS is needed for normal vascular function. During diabetes, aging and hypertension, elevated levels of arginase can compete with NOS for available l-arginine, reducing NO and increasing superoxide (O 2 .-) production via NOS uncoupling. Elevated O 2 .- combines with NO to form peroxynitrite (ONOO -), further reducing NO. Oxidative species increase arginase activity, but the mechanism(s) involved are not known. Our study determined the mechanism involved in peroxynitrite and hydrogen peroxide-induced enhancement in endothelial arginase activity. We hypothesized that oxidative species increase arginase activity through PKC-activated RhoA/Rho kinase (ROCK) pathway. ...
We have previously demonstrated that following cecal ligation and puncture (CLP) there is an increase in lung epithelial apoptosis in a rat model [1]. On the other hand, it has been shown that the rho/rho kinase pathway is involved in mechanisms of several aspects such as endothelial cell dysfunction and apoptosis. However, the role of rho kinase in the concept of sepsis-induced apoptosis has yet to be elucidated. In this study, to investigate the possible contribution of rho/rho kinase signalling in CLP-induced lung injury, rho kinase expression and the possible protective effect of the administration of an inhibitor of rho kinase, (+)-(R)-trans-4-1-aminoethyl-N-4-pyridyl cyclohexanecarboxamide dihydrochloride monohydrate (Y-27632), has been investigated in rats in this model.. Thirty-two male Wistar rats were randomly divided into four groups: (1) sham, (2) CLP, (3) sham + Y27632, (4) CLP + Y27632. Y27632 was administered at 1.5 mg/kg, intaperitoneally, 20 min before performing operations. ...
Leukocyte recruitment is a key feature in ischemiaâ€"reperfusion (I/R)-induced tissue injury. The aim of the present study was to investigate the effect of Rho-kinase inhibition on I/R-provoked leukocyte recruitment in the colon. C57BL/6 mice were subjected to 30 min of ischemia by clamping of the superior mesenteric artery followed by 120 min of reperfusion. Intraperitoneal pretreatment with the selective Rho-kinase inhibitors fasudil (4â€"40 mg/kg) and Y-27632 (1â€"10 mg/kg) was administered prior to induction of colonic I/R. Leukocyteâ€"endothelium interactions were analyzed by intravital fluorescence microscopy. Colonic content of tumour necrosis factor-α (TNF-α) and the CXC chemokines macrophage inflammatory protein-2 (MIP-2) and cytokine-induced neutrophil chemoattractant (KC) were determined by ELISA. Additionally, colonic activity of myeloperoxidase (MPO), a marker of leukocyte infiltration, and malondialdehyde (MDA), were quantified. Fasudil and Y-27632 pretreatment ...

AU - Szasz, Theodora. AU - Webb, R. Clinton. PY - 2014/3/6. Y1 - 2014/3/6. N2 - Background: Lipoxin A4 (LXA4) is a biologically active product generated from arachidonic acid by lipoxygenase action. The production of lipoxins is enhanced by aspirin through acetylation of cyclooxygenase-2, via a mechanism known as aspirin-triggered lipoxin. LXA4 has both anti-inflammatory and proinflammatory actions, the latter being related with reocclusion and restenosis after coronary angioplasty in patients treated with aspirin. However, little is known of the actions of LXA4 on the vasculature. We hypothesized that LXA4 promotes contractile responses and contributes to endothelial dysfunction. Methods: We used aorta from Wistar rats to assess vascular function. Reactive oxygen species (ROS) production and contractile and ...
Transforming acidic coiled-coil-containing protein 2 is a protein that in humans is encoded by the TACC2 gene. Transforming acidic coiled-coil proteins are a conserved family of centrosome- and microtubule-interacting proteins that are implicated in cancer. This gene encodes a protein that concentrates at centrosomes throughout the cell cycle. This gene lies within a chromosomal region associated with tumorigenesis. Expression of this gene is thought to affect the progression of breast tumors. Expression of this gene is also induced by erythropoietin.

Plexins encode receptors for semaphorins, molecular signals guiding cell migration, and axon pathfinding. The mechanisms mediating plexin function are poorly understood. Plexin activation in adhering cells rapidly leads to retraction of cellular processes and cell rounding cell collapse). Here we show that, unexpectedly, this response does not require the activity of Rho-dependent kinase (ROCK) nor the contraction of F-actin cables. Interestingly, integrin-based focal adhesive structures are disassembled within minutes upon plexin activation; this is followed by actin depolymerization and, eventually, by cellular collapse. We also show that plexin activation hinders cell attachment to adhesive substrates, blocks the extension of lamellipodia, and thereby inhibits cell migration. We conclude that plexin signaling uncouples cell substrate-adhesion from cytoskeletal dynamics required for cell migration and axon extension.

Insulin resistance (IR) plays a critical role in metabolic syndrome (MS). Previous studies have demonstrated that activated ROCK is increased in MS patients. However, the effect of Rho-kinase (ROCK) on IR has not been definitely determined. Thus, the aims of the present study were to determine whether ROCK activation induces IR or affects myocardial structure and function, as well as the possible mechanisms underlying this process. Wistar rats fed high fat, high glucose and high salt diet sewed as model of MS and we used transmission electron microscopy, echocardiogram technology, and terminal deoxynucleotidyl transferase-mediated DNA nick-end labeling staining to identify any myocardial damage. The protein levels of MYPT-1 (characteristic of ROCK activation), IRS-1 and AKT were analyzed by immunohistochemistry and Western blotting. In hearts from MS rats, we found increased protein levels of phospho-MYPT-1 and phospho-IRS-1 (Ser307) and decreased phospho-AKT compared to levels in normal rats. ...
The major novel finding of the present study is that exogenously introduced eNOS in VSMCs, with its expression relatively comparable to the endogenous level, markedly inhibited AngII-induced Rho/ROCK pathway activation, and subsequent VSMC migration via its specific inhibition on G12/13 coupled to the AT1 receptor. Overexpression of eNOS such as by adenovirus has been shown to inhibit VSMC proliferation, hypertrophy, as well as migration associated with a wide variety of inhibitions of the upstream signal transductions and gene transcriptions.40-43 However, it is still difficult to conclude whether the observations were translatable to physiological consequences of eNOS-dependent vascular protection, because most of the past studies might overexpress eNOS far beyond the eNOS amount expressed in endothelial cells. For example, marked inhibition of VSMC proliferation by eNOS adenovirus were observed between 150 to 1000 moi,40,41 whereas the inhibition of thymidine incorporation, migration, and ...
