The canonical Wnt/beta-catenin signaling pathway plays diverse roles in embryonic development and disease. Activation of this pathway, likely by Wnt-10b, has been shown to inhibit adipogenesis in cultured 3T3-L1 preadipocytes and in mice. Here, we report that the beta-catenin antagonist Chibby (Cby) is required for adipocyte differentiation. Cby is(More)
In the canonical Wnt pathway, ␤-catenin acts as a key coactivator that stimulates target gene expression through interaction with Tcf/Lef transcription factors. Its nuclear accumulation is the hallmark of active Wnt signaling and is frequently associated with cancers. Chibby (Cby) is an evolutionarily conserved molecule that represses ␤-catenin– dependent(More)
beta-Catenin functions in both cell-cell adhesion and as a transcriptional coactivator in the canonical Wnt pathway. Nuclear accumulation of beta-catenin is the hallmark of active Wnt signaling and is frequently observed in human cancers. Although beta-catenin shuttles in and out of the nucleus, the molecular mechanisms underlying its translocation remain(More)
The Wnt/β-catenin signaling pathway plays crucial roles in embryonic development and in maintenance of organs and tissues in adults. Chibby (Cby) is an evolutionarily conserved molecule that physically interacts with the key downstream coactivator β-catenin and represses its transcriptional activation potential. Although Cby harbors a predicted coiled-coil(More)

Excised bovine and rhesus monkey vitreous samples were subjected to different hydrostatic pressures (0.03, 1 and 2 atm) for 12 hr. At the end of the experiment the samples were frozen in a -70 degrees C dry ice-acetone bath and thereafter maintained in frozen conditions. Differential scanning calorimetry (DSC) was used to obtain freezable water (FW)(More)
