Wnt signaling is essential for embryogenesis and adult tissue homeostasis and contributes to cancer development, especially in the colon. A new essential pathway component, legless, was identified in Drosophila melanogaster. Mice with Cre/loxP-mediated con ...
Immune protection from intracellular pathogens depends on the generation of terminally differentiated effector and of multipotent memory precursor CD8 T cells, which rapidly regenerate effector and memory cells during recurrent infection. The identificatio ...
During early somite stages of development, the broad endoderm-derived foregut and hindgut territories become further subdivided along the antero-posterior axis into organs. One of these organs is the pancreas which serves two major physiological functions: ...
Recent studies implicate Wnt/beta-catenin signaling in lens differentiation (Stump, R. J., et al., 2003. A role for Wnt/beta-catenin signaling in lens epithelial differentiation. Dev Biol;259:48-61). Beta-catenin is a component of adherens junctions and fu ...
The design, simulation, fabrication and characterization of 3-D modulable micro-optical system based on poly-dimethilsiloxane (PDMS) are presented in this paper. This system consists on two uncoupled PDMS lenses with different diameter (2 and 10 mu m). Und ...
The female reproductive hormones estrogens, progesterone, and prolactin control postnatal breast development and are important to breast carcinogenesis. In particular, exposure to progesterone is tightly linked to breast cancer risk. Using the mouse as a m ...
A broad and constantly growing class of diseases, such as Alzheimer's disease, sickle-cell or cataract, involves protein association phenomena as an essential aspect. The common denominator of all the members of this class of molecular condensation disease ...
The Wnt signaling pathway is deregulated in over 90% of human colorectal cancers. beta-Catenin, the central signal transducer of the Wnt pathway, can directly modulate gene expression by interacting with transcription factors of the TCF/LEF family. In the ...
Wnt/beta-catenin and NF-kappaB signaling mechanisms provide central controls in development and disease, but how these pathways intersect is unclear. Using hair follicle induction as a model system, we show that patterning of dermal Wnt/beta-catenin signal ...
Canonical Wnt signaling plays a critical role in stem cell maintenance in epithelial homeostasis and carcinogenesis. Here, we show that in the mouse this role is critically mediated by Bcl9/Bcl9l, the mammalian homologues of Legless, which in Drosophila is ...
