LPP, a LIM protein highly expressed in smooth muscle

An 80-kDa protein, prominently expressed in smooth muscle, was microsequenced and identified as LPP, the product of the lipoma-preferred partner gene (Petit MMR, Mols R, Schoenmakers EFPM, Mandahl N, and Van de Ven WJM. Genomics 36: 118-129, 1996)....

HAX-1, identified by differential display reverse transcription polyerase chain reaction, is overexpressed in lesional psoriasis

Psoriasis is a chronic inflammatory disease characterized by epidermal hyperplasia and an inflammatory infiltrate. The normal differentiation from basal to granular keratinocytes with subsequent apoptosis and cornification is disturbed in the...

Phosphorylation of C/EBPalpha inhibits granulopoiesis

CCAAT/enhancer-binding protein alpha (C/EBPalpha) is one of the key transcription factors that mediate lineage specification and differentiation of multipotent myeloid progenitors into mature granulocytes. Although C/EBPalpha is known to induce...

Translocation of the inhibitor of apoptosis protein c-IAP1 from the nucleus to the Golgi in hematopoietic cells undergoing differentiation: a nuclear export signal-mediated event

The caspase inhibitor and RING finger-containing protein cellular inhibitor of apoptosis protein 1 (c-IAP1) has been shown to be involved in both apoptosis inhibition and signaling by members of the tumor necrosis factor (TNF) receptor family. The...

Lymphotoxin and lipopolysaccharide induce NF-kappaB-p52 generation by a co-translational mechanism

The 'classical' NF-kappaB activation pathway proceeds via IkappaB kinase (IKK)-beta/gamma-mediated phosphorylation, induced ubiquitination and the degradation of small IkappaBs. An alternative, NF-kappaB-inducing kinase and IKK-alpha-dependent...

Nurr1-RXR heterodimers mediate RXR ligand-induced signaling in neuronal cells

The retinoid X receptor (RXR) is essential as a common heterodimerization partner of several nuclear receptors (NRs). However, its function as a bona fide receptor for endogenous ligands has remained poorly understood. Such a role would depend on the...

Chemokine receptor CCR7 induces intracellular signaling that inhibits apoptosis of mature dendritic cells

Acquisition of CCR7 expression is an important phenotype change during dendritic cell (DC) maturation that endows these cells with the capability to migrate to lymph nodes. We have analyzed the possible role of CCR7 on the regulation of the survival...

Human parvovirus B19 nonstructural protein (NS1) induces cell cycle arrest at G1 phase

Human parvovirus B19 infects predominantly erythroid precursor cells, leading to inhibition of erythropoiesis. This erythroid cell damage is mediated by the viral nonstructural protein 1 (NS1) through an apoptotic mechanism. We previously...

Membrane glucocorticoid receptors (mGCR) are expressed in normal human peripheral blood monunuclear cells and up-regulated after in vitro stimulation and in patients with rheumatoid arthritis

Glucocorticoids mediate their therapeutic actions mostly by genomic effects via cytosolic receptors, but some effects are too rapid to be mediated by changes at the genomic level. The detailed mechanisms of these nongenomic actions are still unclear....

Neuromedin U: a Myb-regulated autocrine growth factor for human myeloid leukemias

The c-myb proto-oncogene has been implicated in leukemogenesis, but possible mechanisms remain ill defined. To gain further insight to this process, we used transcript profiling in K562 cells expressing a dominant-negative Myb (MERT) protein. A total...
