Linking actin dynamics and gene transcription to drive cellular motile functions.
Eric N. Olson,Alfred Nordheim +1 more
TL;DR: The discovery that globular actin polymerization liberates myocardin-related transcription factor (MRTF) cofactors induces the nuclear transcription factor serum response factor (SRF) to modulate the expression of genes encoding structural and regulatory effectors of actin dynamics stimulated research to better understand the actin–MRTF–SRF circuit.

Endocytic trafficking of Rac is required for the spatial restriction of signaling in cell migration.

TL;DR: It is demonstrated that a Rab5-to-Rac circuitry controls the morphology of motile mammalian tumor cells and primordial germinal cells during zebrafish development, suggesting that this circuitry is relevant for the regulation of migratory programs in various cells, in both in vitro settings and whole organisms.
Journal ArticleDOI
The chemistry, physiology and pathology of pH in cancer
TL;DR: Elevated metabolism, weakened cell-to-capillary diffusive coupling, and adaptations involving H+/H+-equivalent transporters and extracellular-facing CAs give cancer cells the means to manipulate micro-environmental acidity, a cancer hallmark.
Journal ArticleDOI
The novel lipid raft adaptor p18 controls endosome dynamics by anchoring the MEK-ERK pathway to late endosomes.
Shigeyki Nada,Akihiro Hondo,Atsuko Kasai,Masato Koike,Kazunobu Saito,Yasuo Uchiyama,Masato Okada +6 more
TL;DR: Results indicate that the lipid raft adaptor p18 is essential for anchoring the MEK–ERK pathway to late endosomes, and shed new light on a role of endosomal MEK- ERK pathway in controlling endosome dynamics.
Journal ArticleDOI
Three-dimensional context regulation of metastasis
TL;DR: Synergistic interactions between matrix remodeling and tumor hypoxia influence common mechanisms that maximize tumor progression and cooperate to drive metastasis, which should identify novel therapeutic targets.

Rho GTPases and actin dynamics in membrane protrusions and vesicle trafficking.
TL;DR: Several other members of the Rho family, including Rif, RhoD, TC10 and Wrch1, and also related Rho-of-plants proteins (ROPs) in plants, stimulate actin polymerization and affect plasma membrane protrusion and/or vesicular traffic.
Journal ArticleDOI
The emerging role of lysophosphatidic acid in cancer.
TL;DR: Mechanisms by which LPA production or action could be modulated for cancer therapy are indicated.
Journal ArticleDOI
The Ras-related protein Cdc42Hs and bradykinin promote formation of peripheral actin microspikes and filopodia in Swiss 3T3 fibroblasts.
TL;DR: It is shown that microinjection of the related human Cdc42Hs into Swiss 3T3 fibroblasts induced the formation of peripheral actin microspikes, determined by staining with phalloidin, and that Cdc 42Hs plays an important role in determining mammalian cell morphology.
Journal ArticleDOI
MAP kinases and cell migration
TL;DR: The different kinases in the MAPK family all seem able to regulate cell migration but by distinct mechanisms, and studies of p38 show that this MAPK modulates migration by phosphorylating MAPK-activated protein kinase 2/3 (MAPKAP2/3), which appears to be important for directionality of migration.
Journal ArticleDOI
Integrin-Mediated Activation of Cdc42 Controls Cell Polarity in Migrating Astrocytes through PKCζ
TL;DR: It is shown that the interaction of integrins with extracellular matrix at the newly formed cell front leads to the activation and polarized recruitment of Cdc42, which in turn recruits and activates a cytoplasmic mPar6/PKCzeta complex.
