Involvement of Crm 1 in hepatitis B virus X protein-induced aberrant centriole replication and abnormal mitotic spindles

Hepatitis B virus (HBV) includes an X gene (HBx gene) that plays a critical role in liver carcinogenesis. Because centrosome abnormalities are associated with genomic instability in most human cancer cells, we examined the effect of HBx on...

Novel cell specific and dominant negative anti apoptotic roles of p73 in transformed leukemia cells

Although extensive homology exists between related genes p53 and p73, recent data suggest that the family members have divergent roles. We demonstrate that the differential regulatory roles of p53 family member p73 are highly cell-context and...

Nucleoporation of dendritic cells: efficient gene transfer by electroporation into human monocyte-derived dendritic cells

Dendritic cells (DCs) are ideal accessory cells in the developing field of gene therapy. Although viral transfection of DCs has become widespread, non-viral transfection of DCs has shown disappointing results. Recently, a new technique for...

NPC1 and NPC2 regulate cholesterol homeostasis through generation of LDL cholesterol-derived oxysterols

Mutations in the Niemann-Pick disease genes cause lysosomal cholesterol accumulation and impaired low density lipoprotein (LDL) cholesterol esterification. These findings have been attributed to a block in cholesterol movement from lysosomes to the...

Proteasome inhibition results in TRAIL sensitization of primary keratinocytes by removing the restistance-mediating block of effector caspase maturation

Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) exerts potent cytotoxic activity against transformed keratinocytes, whereas primary keratinocytes are relatively resistant. In several cell types, inhibition of the proteasome sensitizes...

The gene product Murr1 restricts HIV-1 replication in resting CD4+ lymphocytes

Although human immunodeficiency virus-1 (HIV-1) infects quiescent and proliferating CD4+ lymphocytes, the virus replicates poorly in resting T cells. Factors that block viral replication in these cells might help to prolong the asymptomatic phase of...

BPAG1n4 is essential for retrograde axonal transport in sensory neurons

Disruption of the BPAG1 (bullous pemphigoid antigen 1) gene results in progressive deterioration in motor function and devastating sensory neurodegeneration in the null mice. We have previously demonstrated that BPAG1n1 and BPAG1n3 play important...

Evidence that high teleromerase activity may induce a senescent-like growth arrest in human fibroblasts

Expression of the catalytic subunit of human telomerase (hTERT), in normal human fibroblasts allows them to escape replicative senescence. However, we have observed that populations of hTERT-immortalized human fibroblasts contain 3-20% cells with a...

Src family protein-tyrosine kinases alter the function of PTEN to regulate phosphatidylinositol 3-kinase/AKT cascades

Src family protein-tyrosine kinases, which play an important role in signal integration, have been implicated in tumorigenesis in multiple lineages, including breast cancer. We demonstrate, herein, that Src kinases regulate the phosphatidylinositol...

Efficient transfection method for primary cells

Transfection of primary cells and stem cells is a problem in the laboratory routine and further in tissue engineering and gene therapy. Most methods working effectively for cell lines in culture fail to transfect primary cells. Here we describe the...
