In conclusion, EHop-016 has potential as an anticancer compound to block cancer progression via multiple Rac-directed mechanisms.
Loss of merlin in cultured Schwann cells leads to altered morphology, enhanced proliferation and over activation of multiple signalling pathways including Rac GTPase, extracellular regulated kinase (ERK), c-Jun N-terminal kinase (JNK) and phosphatidyl inositol-3 kinase (PI-3 kinase) MAP kinase pathways (Shaw et al., 2001; Kaempchen et al., 2003; Ammoun et al., 2008).
Following activation, Rac proteins initiate multiple signaling pathways that regulate cytoskeletal rearrangements, kinase cascades needed for gene transcription, and assembly of the NADPH oxidase [ 6, 12].
This model maps the optimal RAC problem to a Multiple-choice Multi-dimension 0-1 KnaProblemrobleMMKPMKP), a variation of the classical 0-1 KnaProblemroblem.
Having this in mind, for datasets with multiple sets of X-rays per patient (HCSC-RAC, PEARL, PAZ, EAC, and Wichita) and to account for the within-patient correlation between measurements, linear mixed regression models were used [ 28, 29].
DOI: http://dx.doi.org/10.7554/eLife.02270.015 We report that Pak2, an effector for the small GTPase Rac and Cdc42, is essential for multiple stages of thymocyte development and maturation.
In anti-CD3 pre-treated cells active Rac was enriched in many of the multiple protrusions (Figure 3C), consistent with a role in promoting lamellipodium extension.
The small Rho (p21) GTPases (Rho, Rac, and Cdc42) have been implicated in multiple steps during cellular transformation, including regulation of cytoskeletal reorganization and gene expression [ 1].
In the cohorts with multiple sets of radiographs over time (EAC, Umeå, HCSC-RAC and Wichita) a multivariate normal regression model for longitudinal data was used with radiographic scores as response variable.
Rac GTPases are involved in the regulation of multiple cell functions and have been implicated in the pathology of certain human diseases.
Clostridium difficile Toxin B that inhibits multiple Rho family small GTPases [ 38] and NSC23766 that specifically inhibits Rac [ 39] did not alter the patterning of puncta.
