A novel mechanism for BCR-ABL action: stimulated secretion of CCN3 is involved in growth and differentiation regulation

Chronic myeloid leukemia (CML) is characterized by the presence of the constitutively active BCR-ABL protein tyrosine kinase. Using a multipotent hemopoietic cell line, FDCP-Mix, expressing BCR-ABL tyrosine kinase, we investigated the initial effects...

Role of the Rho GTPase-activating protein RICS in neurite outgrowth

The Rho family of small GTPases, including RhoA, Rac1 and Cdc42, are critical regulators of the actin cytoskeleton. In neuronal systems, Rho GTPase-activating proteins (RhoGAPs) and their substrates, Rho GTPases, have been implicated in regulating...

Ligand-Dependent Cleavage of the P75 Neurotrophin Receptor Is Necessary for NRIF Nuclear Translocation and Apoptosis in Sympathetic Neurons

The p75 neurotrophin receptor regulates neuronal survival, promoting it in some contexts yet activating apoptosis in others. The mechanism by which the receptor elicits these differential effects is poorly understood. Here, we demonstrate that p75 is...

Identification of an Intracellular Trafficking and Assembly Pathway for HIV-1 Gag

Retroviral Gag proteins are membrane-bound polyproteins that are necessary and sufficient for virus-like particle (VLP) formation. It is not known how Gag traffics through the cell or how the site of particle production is determined. Here we use two...

Tumor invasion in the absence of epithelial-mesenchymal transition: podoplanin-mediated remodeling of the actin cytoskeleton

The expression of podoplanin, a small mucin-like protein, is upregulated in the invasive front of a number of human carcinomas. We have investigated podoplanin function in cultured human breast cancer cells, in a mouse model of pancreatic beta cell...

Notch controls proliferation and differentiation of stem cells in a dose-dependent manner

Self-renewal and differentiation of CNS stem cells are regulated by still poorly understood cell-cell interactions. Notch is a well-known cell surface protein that can promote both cell cycle progression and mitotic arrest but the molecular mechanism...

The Three-Substituted Indolinone Cyclin-Dependent Kinase 2 Inhibitor 3-[1-(3H-Imidazol-4-yl)-meth-(Z)-ylidene]-5-methoxy-1,3-dihydro-indol-2-one (SU9516) Kills Human Leukemia Cells via Down-Regulation of Mcl-1 through a Transcriptional Mechanism

Mechanisms of lethality of the three-substituted indolinone and putatively selective cyclin-dependent kinase (CDK)2 inhibitor 3-[1-(3H-imidazol-4-yl)-meth-(Z)-ylidene]-5-methoxy-1,3-dihydro-indol-2-one (SU9516) were examined in human leukemia cells....

Association between Pak1 expression and subcellular localization and tamoxifen resistance in breast cancer patients

BACKGROUND: p21-activated kinase 1 (Pak1) phosphorylates many proteins in both normal and transformed cells. Its ability to phosphorylate and thereby activate the estrogen receptor alpha (ERalpha) potentially limits the effectiveness of antiestrogen...

Production of knockout mice by random or targeted mutagenesis in spermatogonial stem cells

Stem cells represent a unique population of cells with self-renewal capacity. Although they are important therapeutic targets, the genetic manipulation of tissue-specific stem cells has been limited, which complicates the study and practical...

CIB1, a ubiquitously-expressed Ca2+-binding protein-ligand of the InsP3 receptor Ca2+-release channel

A family of Ca2+ binding proteins (CaBPs) was shown to bind to the inositol 1,4,5-trisphosphate receptor (InsP3R) Ca2+ release channel and gate it in the absence of InsP3, establishing them as protein ligands (Yang et al. (2002) Identification of a...
