1. Tratamento com inibidor da Rho quinase em cobais com inflamação pulmonar alérgica crônica: modulação da inflamação eosinofílica, da expressão de citocinas inflamatórias, da matriz extracelular e do estresse oxidativo no parênquima pulmonar / Treatment with Rho-kinase inhibitor in guinea pigs with chronic allergic inflammation: modulation of eosinophilic inflammation, expression of inflammatory cytokines, extracellular matrix and oxidative stress in lung tissue
RATIONALE: Previous studies with Rho-kinase inhibitors suggest a beneficial influence of these drugs in asthma. The relevance of distal lung tissue in functional asthmatic impairment has been intensely emphasized. There have not been any previous studies evaluating the effects of these inhibitors on the modulation of distal lung mechanics and histopathologic

2. Tratamento com inibidor da Rho quinase em cobaias com inflamação alérgica crônica: modulação da inflamação eosinofílica, da expressão de citocinas inflamatórias, da matriz extracelular, do estresse oxidativo e da reatividade de vias aéreas / Treatment with Rho-kinase inhibitor in guinea pigs with chronic allergic inflammation: modulation of eosinophilic inflammation, expression of inflammatory cytokines, extracellular matrix, oxidative stress and airway responsiveness
INTRODUÇÃO: Vários estudos têm mostrado a importância da Rho quinase na modulação da contração do músculo liso, hiperresponsividade das vias aéreas e inflamação. Entretanto, os efeitos do tratamento crônico com um inibidor específico desta via não haviam sido previamente investigados. MÉTODOS: No presente estudo, foram avaliados os efeitos d

3. Efeito de dois probióticos, Saccharomyces boulardii e Saccharomyces cerevisiae linhagem UFMG 905, na resposta inflamatória induzida por Salmonella enterica subsp. enterica sorovar. Typhimurium
Probiotics are defined as viable microorganisms that exhibit a beneficial effect on the host health when ingested in adequate amounts. Many species of bacteria are used for this purpose and the only one yeast used as probiotic in humans is Saccharomyces boulardii. Previous results in our laboratory showed that Saccharomyces cerevisiae strain UFMG 905, isolat

4. The PRK2 kinase is a potential effector target of both Rho and Rac GTPases and regulates actin cytoskeletal organization.
The Ras-related Rho family GTPases mediate signal transduction pathways that regulate a variety of cellular processes. Like Ras, the Rho proteins (which include Rho, Rac, and CDC42) interact directly with protein kinases, which are likely to serve as downstream effector targets of the activated GTPase. Activated RhoA has recently been reported to interact di

5. Yeast Protein Kinases and the RHO1 Exchange Factor TUS1 Are Novel Components of the Cell Integrity Pathway in Yeast
The PKC1-associated mitogen-activated protein (MAP) kinase pathway of Saccharomyces cerevisiae regulates cell integrity by controlling the actin cytoskeleton and cell wall synthesis. Activation of PKC1 occurs via the GTPase RHO1 and the kinase pair PKH1 and PKH2. Here we report that YPK1 and YPK2, an essential pair of homologous kinases and proposed downstre

6. Characterization of a Rac1- and RhoGDI-Associated Lipid Kinase Signaling Complex
Rho family GTPases regulate a number of cellular processes, including actin cytoskeletal organization, cellular proliferation, and NADPH oxidase activation. The mechanisms by which these G proteins mediate their effects are unclear, although a number of downstream targets have been identified. The interaction of most of these target proteins with Rho GTPases

7. The Drosophila Pkn protein kinase is a Rho/Rac effector target required for dorsal closure during embryogenesis
The PKN family of PKC-related protein kinases constitutes the major Rho GTPase-associated protein kinase activities detected in mammalian tissues. However, the biological functions of these kinases are unknown. We have identified a closely related PKN homolog in Drosophila (Pkn) that binds specifically to GTP-activated Rho1 and Rac1 GTPases through distinct

8. Kaposi's Sarcoma-Associated Herpesvirus/Human Herpesvirus 8 Envelope Glycoprotein gB Induces the Integrin-Dependent Focal Adhesion Kinase-Src-Phosphatidylinositol 3-Kinase-Rho GTPase Signal Pathways and Cytoskeletal Rearrangements
Human herpesvirus 8 (HHV-8; Kaposi's sarcoma-associated herpesvirus) envelope glycoprotein gB possesses an RGD motif, interacts with α3β1 integrin, and uses it as one of the entry receptors. HHV-8 induces the integrin-dependent focal adhesion kinase (FAK), a critical step in the outside-in signaling pathways necessary for the subsequent phosphorylation of

9. An SH3 domain-containing GTPase-activating protein for Rho and Cdc42 associates with focal adhesion kinase.
The integrin family of cell surface receptors mediates cell adhesion to components of the extracellular matrix (ECM). Integrin engagement with the ECM initiates signaling cascades that regulate the organization of the actin-cytoskeleton and changes in gene expression. The Rho subfamily of Ras-related low-molecular-weight GTP-binding proteins and several prot

10. The IL-1 receptor and Rho directly associate to drive cell activation in inflammation
IL-1–stimulated mesenchymal cells model molecular mechanisms of inflammation. Binding of IL-1 to the type I IL-1 receptor (IL-1R) clusters a multi-subunit signaling complex at focal adhesion complexes. Since Rho family GTPases coordinately organize actin cytoskeleton and signaling to regulate cell phenotype, we hypothesized that the IL-1R signaling complex

11. Citron Kinase, a Rho-dependent Kinase, Induces Di-phosphorylation of Regulatory Light Chain of Myosin II
Citron kinase is a Rho-effector protein kinase that is related to Rho-associated kinases of ROCK/ROK/Rho-kinase family. Both ROCK and citron kinase are suggested to play a role in cytokinesis. However, no substrates are known for citron kinase. We found that citron kinase phosphorylated regulatory light chain (MLC) of myosin II at both Ser-19 and Thr-18

12. Myotonic Dystrophy Kinase-Related Cdc42-Binding Kinase Acts as a Cdc42 Effector in Promoting Cytoskeletal Reorganization
The Rho GTPases play distinctive roles in cytoskeletal reorganization associated with growth and differentiation. The Cdc42/Rac-binding p21-activated kinase (PAK) and Rho-binding kinase (ROK) act as morphological effectors for these GTPases. We have isolated two related novel brain kinases whose p21-binding domains resemble that of PAK whereas the kinase dom
