PLoS Biology | http://biology.plosjournals.org The Wnt/Wingless (Wg) pathway is an evolutionarily conserved signaling pathway that plays important roles in normal development and cancer, from worms and flies to mice and humans. Two papers, identifying the first components of this pathway, initiated the active research field of Wnt/Wg signal transduction and profoundly influenced my scientific c...

Plasma alkylresorcinols (AR) are useful as dietary biomarkers of wheat and rye whole grain (WG) during interventions but need to be validated in free-living populations. This study estimated the medium-term reproducibility and relative validity of plasma AR as biomarkers of WG and cereal fiber intake. Seventy-two Swedish adults kept 3-d weighed food records on 2 occasions 2-3 mo apart. Of these...

Epidemiological studies have shown an inverse association between dietary intake of whole grains and the risk of chronic disease. This may be related to the ability to mediate a prebiotic modulation of gut microbiota. However, no studies have been conducted on the microbiota modulatory capability of whole-grain (WG) cereals. In the present study, the impact of WG wheat on the human intestinal m...

Pattern formation in developing animals requires that cells exchange signals mediated by secreted proteins. How these signals spread is still unclear. It is generally assumed that they reach their target site either by diffusion or active transport (reviewed in [1] [2]). Here, we report an alternative mode of transport for Wingless (Wg), a member of the Wnt family of signaling molecules. In emb...

Wheat germ (WG) is quite susceptible to deterioration due to the presence of lipase (LA) and lipoxygenase (LOX). Therefore it is indispensable to adopt a stabilization step to decrease the activity of LA and LOX while retaining a maximum level of nutrients. But over-drying can make foodstuffs more susceptible to autoxidation. So a stabilization protocol for inactivating LA and LOX of WG with a ...

Development of organ-specific size and shape demands tight coordination between tissue growth and cell-cell adhesion. Dynamic regulation of cell adhesion proteins thus plays an important role during organogenesis. In Drosophila, the homophilic cell adhesion protein DE-Cadherin (DE-Cad) regulates epithelial cell-cell adhesion at adherens junctions (AJs). Here, we show that along the proximodista...

Spatial and temporal control of Notch and Wingless (Wg) pathways during development is regulated at multiple levels. Here, we present an analysis of Phyllopod as a coordinated regulator of these two critical signal transduction pathways. Phyl specifically helps traffic Notch and Wg pathway components within early endocytic vesicles, thereby controlling the amount of processed signal available f...

Revision history Revision 0 (3 May 2006) First revision Revision 1 (10 June 2006) Incorporated comments from May 2006 CAP WG changed to SET/REPORT DEVICE IDENTIFIER commands instead of the Device Identification VPD page 83h. Revision 2 (7 September 2006) Incorporated comments from July 2006 CAP WG renamed to SET/REPORT IDENTIFYING INFORMATION to avoid overuse of “identifier”, increased the info...
