Abstract

The transcription factor C/EBP is known to be able to bind to two different classes of sites, a CAAT-box and one present in a number of viral enhancers. In this paper we show using band-shift assays, methylation interference and footprinting that C/EBP is also able to bind with high affinity to ATF/CRE sites. Competition with mutant ATF sites and methylation interference indicate that C/EBP may be able to bind to the ATF/CRE sites by virtue of their homology to the enhancer core elements. Furthermore, we show that C/EBP is able to direct transcription from this site in transient transfection experiments and that mutations in the ATF binding site that impair DNA binding also effect the ability of C/EBP to stimulate transcription.

Amino acid limitation induces expression of ATF5 mRNA at the post-transcriptional level.

ATF5 is a transcription factor in the cAMP response element (CRE)-binding protein/activating transcription factor (CREB/ATF) family. We studied the effect of amino acid limitation on ATF5 mRNA levels in a mammalian cell line. Northern-blot analysis demonstrated that limitation of a single amino acid, glutamine, methionine, or leucine, resulted in increased ATF5 mRNA levels in HeLaS3 cells. This resulted, at least in part, from increased half-life of the ATF5 mRNA transcript. Cycloheximide inhibited the increase in ATF5 mRNA expression induced by glutamine limitation, indicating that it was dependent on de novo protein synthesis. Moreover, rapamycin had no effect on basal ATF5 mRNA expression or on increased expression induced by glutamine limitation. These results indicate that amino acid limitation regulates ATF5 mRNA expression during post-transcription in a rapamycin-independent manner. The potential role for ATF5 in protecting cells from amino acid-limitation is of considerable interest.

A gene transfer comparative study of HSA-conjugated antiangiogenic factors in a transgenic mouse model of metastatic ocular cancer.

Different antiangiogenic and antimetastatic recombinant adenoviruses were tested in a transgenic mouse model of metastatic ocular cancer (TRP1/SV40 Tag transgenic mice), which is a highly aggressive tumor, developed from the pigmented epithelium of the retina. These vectors, encoding amino-terminal fragments of urokinase plasminogen activator (ATF), angiostatin Kringles (K1-3), endostatin (ES) and canstatin (Can) coupled to human serum albumin (HSA) were injected to assess their metastatic and antiangiogenic activities in our model. Compared to AdCO1 control group, AdATF-HSA did not significantly reduce metastatic growth. In contrast, mice treated with AdK1-3-HSA, AdES-HSA and AdCan-HSA displayed significantly smaller metastases (1.19+/-1.19, 0.87+/-1.5, 0.43+/-0.56 vs controls 4.04+/-5.12 mm3). Moreover, a stronger inhibition of metastatic growth was obtained with AdCan-HSA than with AdK1-3-HSA (P=0.04). Median survival was improved by 4 weeks. A close correlation was observed between the effects of these viruses on metastatic growth and their capacity to inhibit tumor angiogenesis. Our study indicates that systemic antiangiogenic factors production by recombinant adenoviruses, particularly Can, might represent an effective way of delaying metastatic growth via inhibition of angiogenesis.

Beta2 adrenergic receptor activation stimulates pro-inflammatory cytokine production in macrophages via PKA- and NF-kappaB-independent mechanisms.

Activation of the beta(2) adrenergic receptor (beta(2)AR) located on macrophages has been reported to possess anti-inflammatory properties, inhibiting nuclear factor kappaB (NF-kappaB) activation and cytokine production induced by pro-inflammatory stimuli. Here, we show that activation of the beta(2)AR in the absence of pro-inflammatory stimuli produced up to an 80- and 8-fold increase in IL-1beta and IL-6 transcripts, respectively, in the RAW 264.7 murine macrophage cell line. This increase in mRNA expression was accompanied by a significant increase in IL-1beta and IL-6 protein production. Pre-treatment of RAW cells with pharmacological inhibitors of protein kinase A (PKA) or NF-kappaB pathway failed to block this cytokine increase. Instead, the beta(2)AR-mediated increase in cytokines required activation of both the B-raf-ERK1/2 and p38 pathways. Treatment of RAW cells with the exchange protein directly activated by cAMP (EPAC) agonist also resulted in the up-regulation of IL-1beta and IL-6 transcripts. Examination of the main transcription factors downstream of the ERK1/2 and p38 signaling revealed that beta(2)AR activation resulted in the stimulation of CRE-, but not C/EBPbeta-, ETS-, or NF-kappaB-dependent transcription. Western blot analysis further showed that among the transcription factors which recognize the CRE-binding site, ATF-1 and ATF-2 but not CREB proteins were phosphorylated in an ERK1/2- and p38-dependent manner. Collectively, these results demonstrate that beta(2)ARs possess pro-inflammatory properties and that their activation leads to IL-1beta and IL-6 production through ERK1/2- and p38-dependent activation of ATF-1 and ATF-2 transcription factors.
