The aryl hydrocarbon receptor attenuates tobacco smoke induced cyclooxygenase-2 and prostaglandin production in lung fibroblasts through regulation of the NF-kappa B family member RELB

Diseases such as chronic obstructive pulmonary disease and lung cancer caused by cigarette smoke affect millions of people worldwide. The aryl hydrocarbon receptor (AhR) is a ligand activated transcription factor that influences responses to certain...

Differential regulation and role of interleukin-1 receptor associated kinase-M in innate immunity signaling

Toll-like-receptor mediated signaling is finely regulated by a complex intracellular protein network including the interleukin-1 receptor associate kinases (IRAKs). IRAK-4, 1, and 2 may positively regulate innate immunity signaling through the...

Intestinal bacteria trigger T cell-independent immunoglobulin A(2) class switching by inducing epithelial-cell secretion of the cytokine APRIL

Bacteria colonize the intestine shortly after birth and thereafter exert several beneficial functions, including induction of protective immunoglobulin A (IgA) antibodies. The distal intestine contains IgA(2), which is more resistant to bacterial...

A major role of PKC theta and NFkappaB in the regulation of hTERT in human T lymphocytes

Expression of the telomerase catalytic subunit (TERT) is the rate-limiting determinant of telomerase activity in most human cells. In this work, we examined the participation of protein kinase C (PKC) in the regulation of hTERT expression in human T...

The collapsin response mediator protein 1 (CRMP-1) and the promyelocytic leukemia zinc finger protein (PLZF) bind to UDP-N-acetylglucosamine 2-epimerase/N-acetylmannosamine kinase (GNE), the key enzyme of sialic acid biosynthesis

Sialic acids (Sia) are expressed as terminal sugars in many glycoconjugates. They are involved in a variety of cell-cell interactions and therefore play an important role during development and regeneration. UDP-N-acetylglucosamine...

Bortezomib-Resistant Nuclear Factor-kappaB Activity in Multiple Myeloma Cells

Bortezomib (Velcade/PS341), a proteasome inhibitor used in the treatment of multiple myeloma (MM), can inhibit activation of nuclear factor-kappaB (NF-kappaB), a family of transcription factors often deregulated and constitutively activated in...

Androgen receptor auto-regulates its expression by a negative feedback loop through upregulation of IFI16 protein

Expression of androgen receptor (AR) in prostate epithelial cells is thought to regulate cell proliferation, differentiation, and survival. However, the molecular mechanisms remain unclear. We report that re-expression of AR in PC-3 human prostate...

Changes in cardiac lipid metabolism during sepsis: the essential role of very low-density lipoprotein receptors

OBJECTIVE: Sepsis accompanies myocardial dysfunction and dynamic alterations of cardiac metabolism. We have recently demonstrated that the very low-density lipoprotein receptor (VLDL-R), which is abundantly expressed in the heart, plays a key role in...

Hint2 is expressed in the mitochondria of H295R cells and is involved in steroidogenesis

Hint2 belongs to the superfamily of histidine triad (HIT) hydrolase enzymes. Recently, it has been shown to influence the mitochondria-dependent apoptosis occurring in hepatocytes, but its mechanism of action is still obscure. Here, we demonstrate...

Activation of phospholipase D by 8-Br-cAMP occurs through novel pathway involving Src, Ras, and ERK in human endometrial stromal cells

We investigated the mechanism of 8-Br-cAMP-mediated phospholipase D (PLD) activation using a primary cell culture system of human endometrial stromal cells (ES cells). PLD activity was increased by the treatment of ES cells with 8-Br-cAMP, maximally...
