Contact guidance mediated three-dimensional cell migration is regulated by Rho/ROCK-dependent matrix reorganization.
Cells generate mechanical force to organize the extracellular matrix (ECM) and drive important developmental and reparative processes. Likewise, tumor cells invading into three-dimensional (3D) matrices remodel the ECM microenvironment. Importantly, we previously reported a distinct radial reorganization of the collagen matrix surrounding tumors that facilitates local invasion. Here we describe...
متن کاملBasal extracellular signal-regulated kinase activity modulates cell-cell and cell-matrix interactions.
Suppression of the basal extracellular signal-regulated kinase (ERK) activity in PC12 cells markedly altered their phenotype. Wild-type cells grew in a dissociated pattern adherent to the substrate. The stable expression of an ERK inhibitory mutant resulted in the formation of calcium-dependent aggregates which were less adherent to the substrate. Concomitantly, the cells reorganized their acti...

Roles of cell protrusions as initial and dynamic mediators of cell–cell and cell–ECM interactions Filopodia have well-established roles in sampling the local environment and making initial cell–ECM contacts at the leading edge of many cell types. Filopodial-like structures, termed “epithelial zippers,” can mediate initial contacts between epithelial cells that culminate in assembly of cell–cell...
متن کاملParthenolide induces MITF-M downregulation and senescence in patient-derived MITF-Mhigh melanoma cell populations
The activity of the M isoform of microphthalmia-associated transcription factor (MITF-M) has been attributed to regulation of differentiation, proliferation, survival and senescence of melanoma cells. MITF expression was shown to be antagonized by the activation of transcription factor NF-κB. Parthenolide, an inhibitor of NF-κB, has not been yet reported to affect MITF-M expression. Our results...

Intracellular interactions shape cells Intestinal epithelial cells build a brush border of microvilli at their apical surfaces that mediates nutrient absorption and host defense. Scott Crawley (Tyska Laboratory, Vanderbilt University Medical Center) showed that brush border assembly is driven by trans interactions between protocadherin-24 and mucin-like protocadherin at the tips of adjacent mic...
