Characterization of c-Src during Listeria monocytogenes cell-to-cell spreading.

Listeria monocytogenes replicates within host cells and spreads from cell-to-cell using actin-based motility. Cell-to-cell movement of L. monocytogenes is achieved by creating actin-rich membrane protrusions (listeriopods), which generate corresponding invaginations in adjacent cells through caveolin-mediated endocytosis.

AP39, a novel mitochondria-targeted hydrogen sulfide donor, promotes cutaneous wound healing in an in vivo murine model of acute frostbite injury.

Frostbite injury refers to cold tissue injury which typically affects the peripheral areas of the body, and is associated with limb loss and high rates of morbidity. Historically, treatment options have been limited to supportive care, leading to suboptimal outcomes for affected patients. The pathophysiology of frostbite injury has been understood in recent years to share similarity with that of cold ischemia-reperfusion injury as seen in solid organ transplantation, of which mitochondria play an important contributing role.

Pharmacological Inhibition of Endogenous Hydrogen Sulfide Production Slows Bladder Cancer Progression in an Intravesical Murine Model.

Present bladder cancer therapies have relatively limited therapeutic impact and account for one of the highest lifetime treatment costs per patient. Therefore, there is an urgent need to explore novel and optimized treatment strategies. The present study investigated the effects of inhibiting endogenous hydrogen sulfide (HS) production on bladder cell viability and in vivo tumor progression.

Effect of Sodium Thiosulfate Pre-Treatment on Renal Ischemia-Reperfusion Injury in Kidney Transplantation.

We recently reported in a rat model of kidney transplantation that the addition of sodium thiosulfate (STS) to organ preservation solution improved renal graft quality and prolonged recipient survival. The present study investigates whether STS pre-treatment would produce a similar effect. In vitro, rat kidney epithelial cells were treated with 150 μM STS before and/or during exposure to hypoxia followed by reoxygenation.

Inhibition of NK cell cytotoxicity by tubular epithelial cell expression of Clr-b and Clr-f.

NK cells participate in ischemia reperfusion injury (IRI) and transplant rejection. Endogenous regulatory systems may exist to attenuate NK cell activation and cytotoxicity in IRI associated with kidney transplantation. A greater understanding of NK regulation will provide insights in transplant outcomes and could direct new therapeutic strategies.
