PKD1/PKCµ promotes alphavbeta3 integrin recycling and delivery to nascent focal adhesions

To identify kinases that regulate integrin recycling, we have immunoprecipitated alphavbeta3 integrin from NIH 3T3 fibroblasts in the presence and absence of primaquine (a drug that inhibits receptor recycling and leads to accumulation of integrins...

WHIM syndromes with different genetic anomalies are accounted for by impaired CXCR4 desensitization to CXCL12

The WHIM syndrome is a rare immunodeficiency disorder characterized by Warts, Hypogammaglobulinemia, Infections and Myelokathexis. Dominant heterozygous mutations of the gene encoding CXCR4, a G protein-coupled receptor with a unique ligand, CXCL12,...

Recognition sequences for the GYF domain reveal a possible spliceosomal function of CD2BP2

Protein-protein interactions are often mediated by small domains that recognize solvent-exposed peptide sequences. Deciphering the recognition code for these adapter domains is an important step in the understanding of multi-protein assemblies. Here,...

Dynamic molecular interactions linking the T cell antigen receptor to the actin cytoskeleton

T cell receptor (TCR) engagement leads to actin polymerization at the site of T cell contact with antigen-presenting cells. Here we have studied the dynamic activity of proteins involved in regulating actin polymerization in live T cells after...

Identification of genes regulated by 2-methoxyestradiol (2ME2) in multiple myeloma cells using oligonucleotide arrays

Our previous study demonstrated that 2-methoxyestradiol (2ME2), an estrogen derivative, induces apoptosis in multiple myeloma (MM) cells; however, the related transcriptional events are unclear. In the present study, we used oligonucleotide...

Critical role of N-cadherin in myofibroblast invasion and migration in vitro stimulated by colon-cancer-cell-derived TGF- or wounding

Invasion of stromal host cells, such as myofibroblasts, into the epithelial cancer compartment may precede epithelial cancer invasion into the stroma. We investigated how colon cancer-derived myofibroblasts invade extracellular matrices in vitro in...

Association of ABCA1 with Syntaxin 13 and Flotillin-1 and Enhanced Phagocytosis in Tangier Cells

The ATP-binding cassette transporter A1 (ABCA1) facilitates the cellular release of cholesterol and choline-phospholipids to apolipoprotein A-I (apoA-I) and several studies indicate that vesicular transport is associated with ABCA1 function....

Targeting mitochondria to overcome conventional and bortezomib/proteasome inhibitor PS-341 resistance in multiple myeloma (MM) cells

Bortezomib (PS-341), a selective inhibitor of proteasomes, induces apoptosis in multiple myeloma (MM) cells; however, prolonged drug exposure may result in cumulative toxicity and the development of chemoresistance. Here we show that combining...

Role for Rab7 in maturation of late autophagic vacuoles

The small GTP binding protein Rab7 has a role in the late endocytic pathway and lysosome biogenesis. The role of mammalian Rab7 in autophagy is, however, unknown. We have addressed this by inhibiting Rab7 function with RNA interference and...

Distinct cAMP signaling pathways differentially regulate 2C-adrenoceptor expression: role in serum induction in human arteriolar smooth muscle cells

The physiological role of alpha(2)-adrenoceptors (alpha(2)-ARs) in cutaneous, arteriolar, vascular smooth muscle cells (VSMs) is to mediate cold-induced constriction. In VSMs cultured from human cutaneous arterioles, there is a selective increase in...
