Delayed inferior epigastric bleed following robotic assisted laparoscopic prostatectomy: An algorithmic approach.

Definitive surgical treatment for prostate cancer continues to evolve with robotic prostatectomy being the preferred technique. This technique has led to decreased blood loss and transfusion rates. Although uncommon, this case report presents a rare incident of delayed inferior epigastric bleed from a port site after a robotic prostatectomy.

Phosphorylation Modulates the Coregulatory Protein Exchange of the Nuclear Receptor Pregnane X Receptor.

The pregnane X receptor (PXR), or nuclear receptor (NR) 1I2, is a ligand-activated NR superfamily member that is enriched in liver and intestine in mammals. Activation of PXR regulates the expression of genes encoding key proteins involved in drug metabolism, drug efflux, and drug transport. Recent mechanistic investigations reveal that post-translational modifications (PTMs), such as phosphorylation, play a critical role in modulating the bimodal function of PXR-mediated transrepression and transactivation of target gene transcription.
