Differential localization and function of ADP-ribosylation factor-6 in anergic human T cells: a potential marker for their identification

Anergy is a state of immunologic tolerance in which T cells are viable but incapable of responding to antigenic stimulation. Recent data indicate that anergic cells have a distinct gene expression program that determines their unique function. In...

JNK-dependent release of mitochondrial protein, SMAC during apoptosis in multiple myeloma (MM) cells

Smac, second mitochondria-derived activator of caspases, promotes apoptosis via activation of caspases. Previous studies have shown that c-Jun NH(2)-terminal kinase (JNK) is involved in regulating another mitochondrial protein, cytochrome c during...

Combined spatial and enzymatic regulation of Csk by cAMP and protein kinase A inhibits T cell receptor signaling

Raft-associated Csk controls signaling through the T cell receptor (TCR) and was mainly anchored to Cbp/PAG (phosphoprotein associated with glycosphingolipid-enriched membrane domains). Treatment of cells with the cAMP-elevating agent prostaglandin...

Pericyte-specific expression of RGs5: implications for PDGF and EDG receptor signaling during vascular maturation

RGS proteins finely tune heterotrimeric G-protein signaling. Implying the need for such fine-tuning in the developing vascular system, in situ hybridization revealed a striking and extensive expression pattern of Rgs5 in the arterial walls of...

A central role for the Jun-N-terminal kinase pathway in mediating the antagonistic activity of pro-inflammatory cytokines against transforming growth factor-beta-driven Smad3/4 specific gene expression

We have focused our attention on the molecular events underlying the antagonistic activities of pro-inflammatory cytokines against transforming growth factor-beta (TGF-beta)/SMAD signaling. Using jnk1/2-knockout (jnk(-/-)) and I kappa B...

Pleiotropic defects in lymphocyte activation caused by caspase-8 mutations lead to human immunodeficiency

Apoptosis is a form of programmed cell death that is controlled by aspartate-specific cysteine proteases called caspases. In the immune system, apoptosis counters the proliferation of lymphocytes to achieve a homeostatic balance, which allows potent...

Distinct involvement of the Jun-N-terminal kinase and NF-kappaB pathways in the expression of the human COL1A2 gene by TNF-alpha

We used a gene knockout approach to elucidate the specific roles played by the Jun-N-terminal kinase (JNK) and NF-kappaB pathways downstream of TNF-alpha in the context of alpha(2) type I collagen gene (COL1A2) expression. In JNK1-/--JNK2-/- (JNK-/-)...

Coordinate notch 3-hairy related transscription factor pathway regulation in response to arterial injury: mediator role of PDGF and ERK

The Notch family of receptors and downstream effectors plays a critical role in cell fate determination during vascular ontogeny. Moreover, the human cerebral autosomal dominant artriopathy with subcortical infarcts and leukoencephalopathy (CADASIL)...

Interactions of human myosin Va isoforms, endogenously expressed in human melanocytes, are tightly regulated by the tail domain

Primary human epidermal melanocytes express six endogenous isoforms of the human actin-associated myosin Va motor protein, involved in organelle transport. As isoforms containing exon F are most abundant in melanocytes, we hypothesized that these...

Shear stress-induced endothelial cell polarization in mediated by Rho and Rac but not Cdc42 or PI 3-kinase

Shear stress induces endothelial polarization and migration in the direction of flow accompanied by extensive remodeling of the actin cytoskeleton. The GTPases RhoA, Rac1, and Cdc42 are known to regulate cell shape changes through effects on the...
