Monocyte counts and prostate cancer outcomes in white and black men: results from the SEARCH database.

Purpose: Circulating inflammatory markers may predict prostate cancer (PC) outcomes. For example, a recent study showed that higher peripheral blood monocyte counts were associated with aggressive PC in Asian men undergoing radical prostatectomy (RP). Herein, we investigated whether peripheral monocyte count can predict long-term PC outcomes after RP in black and white men.

Detection of Cytosolic via a C-Terminal Triple-Arginine Motif of GBP1 Inhibits Actin-Based Motility.

Dynamin-like guanylate binding proteins (GBPs) are gamma interferon (IFN-γ)-inducible host defense proteins that can associate with cytosol-invading bacterial pathogens. Mouse GBPs promote the lytic destruction of targeted bacteria in the host cell cytosol, but the antimicrobial function of human GBPs and the mechanism by which these proteins associate with cytosolic bacteria are poorly understood. Here, we demonstrate that human GBP1 is unique among the seven human GBP paralogs in its ability to associate with at least two cytosolic Gram-negative bacteria, and Rough lipopolysaccharide (LPS) mutants of colocalize with GBP1 less frequently than wild-type does, suggesting that host recognition of O antigen promotes GBP1 targeting to Gram-negative bacteria.
