Abstract 1. The expression and the activity of cytochromes P450 (CYPs) can be elevated by the activation of nuclear receptors. The pregnane X receptor (PXR, or nuclear receptor NR1I2) is a ligand-activated transcription factor that mediates responses to diverse xenobiotics and endogenous chemicals. Here we investigated the regulatory role of PXR ...

Disruption of the interaction of bromo and extra terminal (BET) proteins with acetylated histones using small molecule inhibitors suppresses Myc-driven cancers and TLR-induced inflammation in mouse models. The predominant mechanism of BET inhibitor action is to suppress BET-mediated recruitment of positive transcription elongation factor b (pTEFb) and, thus, transcription elongation. ...

Oncolytic viruses exploit common molecular changes in cancer cells, which are not present in normal cells, to target and kill cancer cells. Ras transformation and defects in type I interferon (IFN)-mediated antiviral responses are known to be the major mechanisms underlying viral oncolysis. Previously, we demonstrated that oncogenic RAS/Mitogen-activated protein ...

The expression of 2[prime]-5[prime]-Oligoadenylate synthetases (OASs) is induced by type 1 Interferons (IFNs) in response to viral infection. The OAS proteins have a unique ability to produce 2[prime]-5[prime] Oligoadenylates, which bind and activate the ribonuclease RNase L. The RNase L degrades cellular RNAs which in turn inhibits protein translation and ...

IFN-α production by pDCs regulates host protection against viruses and is implicated in autoimmune pathology. Human pDCs express high levels of IL-18R, but little is known of its role in pDC function. We report that IL-18R signaling negatively regulates IFN-α production through activation-induced splicing of IL-18Rα in human pDCs. Our ...

SIRT1 is a NAD(+)-dependent enzyme that affects metabolism by deacetylating key transcriptional regulators of energy expenditure. Here, we tested whether deletion of PARP-2, an alternative NAD(+)-consuming enzyme, impacts on NAD(+) bioavailability and SIRT1 activity. Our results indicate that PARP-2 deficiency increases SIRT1 activity in cultured myotubes. However, this increase was ...

Recent studies suggested that dihydrotestosterone (DHT)-driven alteration in the autocrine and paracrine factors may be a key to androgen-potentiated balding. Also, we recently claimed that DHT-inducible dickkopf-1 (DKK-1) is one of the key factors involved in the androgen-potentiated balding. Here, we investigated whether L-ascorbic acid 2-phosphate (Asc 2-P), a derivative ...
