Causes, consequences, and remedies for growth-induced solid stress in murine and human tumors

Stylianopoulos, T.; Martin, J. D.; Chauhan, V. P.; Jain, S. R.; Diop-Frimpong, B.; Bardeesy, N.; Smith, B. L.; Ferrone, C. R.; Hornicek, F. J.; Boucher, Y.; Munn, L. L.; Jain, R. K. (2012)

The presence of growth-induced solid stresses in tumors has been suspected for some time, but these stresses were largely estimated using mathematical models. Solid stresses can deform the surrounding tissues and compress ...

Character displacement of song and morphology in African tinkerbirds

Kirschel, A. N. G.; Blumstein, Daniel T.; Smith, T. B. (2009)

Divergence in acoustic signals between populations of animals can lead to species recognition failure, reproductive isolation, and speciation. Character displacement may facilitate coexistence of species in natural ...

A comparison of terrestrial isopod communities among different habitat types on Mt. Chelmos (Peloponnisos, Greece)

Sfenthourakis, Spyros; Skouras, D.; Anastasiou, Yiannis (2012)

The mountainous communities of terrestrial isopods (Crustacea, Oniscidea) have not been ex-tensively studied so far, even though they can offer important insights to the structuring of iso-pod diversity, to the role of ...

Composition and histone substrates of polycomb repressive group complexes change during cellular differentiation

Kuzmichev, A.; Margueron, R.; Vaquero, A.; Preissner, T. S.; Scher, M.; Kirmizis, Antonis; Ouyang, X.; Brockdorff, N.; Abate-Shen, C.; Farnham, P.; Reinberg, D. (2005)

Changes in the substrate specificities of factors that irreversibly modify the histone components of chromatin are expected to have a profound effect on gene expression through epigenetics. Ezh2 is a histone-lysine ...

Design of a modified mouse protein with ligand binding properties of its human analog by molecular dynamics simulations: The case of C3 inhibition by compstatin

Tamamis, Phanourios; Pierou, P.; Mytidou, C.; Floudas, C. A.; Morikis, D.; Archontis, Georgios Z. (2011)

The peptide compstatin and its derivatives inhibit the complement-component protein C3 in primate mammals and are potential therapeutic agents against the unregulated activation of complement in humans, but are inactive ...

Dietary Soy Isoflavones and Estrone Protect Ovariectomized ERαKO and Wild-Type Mice from Carcinogen-Induced Colon Cancer

Guo, J. -Y; Li, X.; Browning Jr., J. D.; Rottinghaus, G. E.; Lubahn, D. B.; Constantinou, Andreas I.; Bennink, M.; MacDonald, R. S. (2004)

Consumption of soy foods has been weakly associated with reduced colon cancer risk. Colon cancer risk is influenced by estrogen exposure, although the mechanism through which this occurs is not defined. Conversion of ...

Differential expression of the rat retinoid X receptor γ gene during skeletal muscle differentiation suggests a role in myogenesis

Georgiades, Pantelis; Brickell, P. M. (1997)

Even though previous studies have shown that transcripts encoding the murine retinoid X receptor γ (RXRγ) are present in skeletal muscle of mouse embryos and that cultured myoblasts are induced to differentiate upon retinoid ...

Ectopic expression of individual E(spl) genes has differential effects on different cell fate decisions and underscores the biphasic requirement for Notch activity in wing margin establishment in Drosophila

Ligoxygakis, P.; Bray, S. J.; Apidianakis, Yiorgos; Delidakis, Christos (1999)

A common consequence of Notch signalling in Drosophila is the transcriptional activation of seven Enhancer of split [E(spl)] genes, which encode a family of closely related basic-helix-loop-helix transcriptional repressors. ...
