19398497 Kang JH, Chang SY, Jang HJ, Kim DB, Ryu GR, Ko SH, Jeong IK, Jo YH, Kim MJ: Exendin-4 inhibits interleukin-1beta-induced iNOS expression at the protein level, but not at the transcriptional and posttranscriptional levels, in RINm5F beta-cells.

J Lab Clin Med. 2006 Apr;147(4):182-90.


Janus kinase (JAK)-induced phosphorylation of STAT1/3/6, which acts at translational regulation, seemed to be crucial because chemical inhibition of JAK as well as cycloheximide (CHX) abolished both the phosphorylation of STAT1/3/6 and the IFN-gamma-induced inhibitory effect.

Various stimulatory compounds that increase receptor mRNA stability only (human and bovine sera, cycloheximide) or that stimulate NF-kappaB nuclear translocation and both mRNA concentration and stability [interleukin (IL)-1beta, phorbol 12-myristate 13-acetate (PMA)] all increased the density of binding sites for the tritiated B1 receptor agonist [3H] Lys-des-Arg9-bradykinin (without change in receptor affinity) in cell-based assays.
Small interfering RNA assays indicated that NF-kappaB p65 is necessary for the effective expression of the cell surface B1 receptor under basal or IL-1beta, fetal bovine serum (FBS), or PMA stimulation conditions.

This induction was inhibited by actinomycin D (5 mM), cycloheximide (5 mM), and NF-kappaB inhibitors, including pyrrolidine dithiocarbamate (PDTC, 1 mM), aspirin (2.5 mM), and sodium salyicylate (2.5 mM).
Stimulation with NE was rapidly followed by association of IRAK with MyD88, phosphorylation of IkappaBalpha, and nuclear translocation of p65 with increased transactivation activity.

In CMVEC from mice and newborn pigs, 15 ng/ml TNF-alpha alone, or with 10 microg/ml cycloheximide (CHX) caused apoptosis detected by nuclear translocation of p65 NF-kappaB, caspase-3 activation, DNA fragmentation, cell-cell contact destabilization, and cell detachment.

METHODS: Human articular chondrocytes were treated with IL-1beta in the presence of TGFbeta1, pyrrolidine dithiocarbamate (a repressor of the NF-kappaB pathway), or cycloheximide.
In addition, transient transfections of p65 expression vector or p65-targeted short hairpin RNA were performed to define the effect of NF-kappaB on Smad7 expression.

Cycloheximide did not antagonize the inhibitory effects of TNF on GH-inducible IGF-I expression.
Cotransfection of CWSV-1 cells with expression vectors for p65 alone or p50 and p65 together inhibited GH-inducible Spi 2.1 and IGF-I promoter activity.
