Bacterial cupredoxin azurin as an inducer of apoptosis and regression in human breast cancer
(2004)Azurin, a copper-containing redox protein released by the pathogenic bacterium Pseudomonas aeruginosa, is highly cytotoxic to the human breast cancer cell line MCF-7, but is less cytotoxic toward p53-negative (MDA-MB-157) ...

Homeostasis in Infected Epithelia: Stem Cells Take the Lead
(2009)To maintain tissue homeostasis and avoid disease, epithelial cells damaged by pathogens need to be readily replenished, and this is mainly achieved by the activation of stem cells. In this Short Review, we discuss recent ...

Profiling early infection responses: Pseudomonas aeruginosa eludes host defenses by suppressing antimocrobial peptide gene expression
(2005)Insights into the host factors and mechanisms mediating the primary host responses after pathogen presentation remain limited, due in part to the complexity and genetic intractability of host systems. Here, we employ the ...

Resonance Raman detection of a ferrous five-coordinate nitrosylheme b3 complex in cytochrome cbb3 oxidase from Pseudomonas stutzeri
(2002)Understanding the chemical nature of the nitric oxide (NO) moiety of nitrosylheme copper oxidases is crucial for elucidation of the NO activation process. In the present work, direct resonance Raman spectroscopic observation ...

Time-resolved step-scan Fourier transform infrared investigation of heme-copper oxidases: Implications for O2 input and H 2O/H+ output channels
(2004)We have applied FTIR and time-resolved step-scan Fourier transform infrared (TRS2-FTIR) spectroscopy to investigate the dynamics of the heme-CuB binuclear center and the protein dynamics of mammalian aa3, Pseudomonas ...
