A cell-permeable indenopyrazole compound that displays potent antiproliferative properties in several human tumor cell lines (IC50<33 nM). Shown to act as an ATP-competitive and reversible inhibitor of PDGFR (IC50 = 4.2 nM and 45 nM for -β and -α, respectively) and c-Abl (IC50 = 22 nM). Exhibits less activity towards Lck, c-Src, and Fyn (IC50 = 100 nM, 185 nM and 378 nM, respectively) and exhibits little or no inhibition toward VEGFR, HER-2, Cdk′s-1,-2,-4 &-7, bFGFR-1 and EGFR (IC50 = 3.1 µM, >10 µM, >10 µM, 45.8 µM and >100 µM, respectively).

Low circulating phosphate (Pi) leads to rickets, characterized by expansion of the hypertrophic chondrocytes (HCs) in the growth plate due to impaired HC apoptosis. Studies in HCs demonstrate that Pi activates the Raf/MEK/ERK1/2 and mitochondrial apoptotic pathways. To determine how
The isotropic or anisotropic organization of biological extracellular matrices has important consequences for tissue function. We study emergent anisotropy using fibroblasts that generate varying degrees of matrix alignment from uniform starting conditions. This reveals that the early migratory paths of
In mammals, perivascular cell-derived scarring after spinal cord injury impedes axonal regrowth. In contrast, the extracellular matrix (ECM) in the spinal lesion site of zebrafish is permissive and required for axon regeneration. However, the cellular mechanisms underlying this interspecies difference
