Genome-wide gene expression profiling of ischemia-reperfusion injury in rat kidney, intestine and skeletal muscle implicate a common involvement of MAPK signaling pathway.

The mechanisms of ischemia‑reperfusion (I/R) injury have not been fully elucidated to date. In order to determine the genetic involvement across different organs during I/R injury, a DNA microarray approach was used to analyze the gene expression profiles of the kidney, intestine, and skeletal muscle in a rat model of I/R injury. Fifteen male Lewis rats were divided randomly into three different organ groups; a sham operation (control group), 60‑min‑ischemia (Is group) only, and 60‑min‑ischemia plus 60‑min‑reperfusion (I/R group), respectively.

Proteomic profiling of oxidative stress in human victims of traffic-related injuries after lower limb revascularization and indication for secondary amputation.

Microsurgical replantation and revascularization are frequently performed to salvage devascularized severe lower-extremity fractures in the human victims of road traffic-related injuries. However, some patients require secondary amputation within 1 week of successful revascularization due to tissue necrosis and sepsis. Enhanced efforts to understand the underlying molecular mechanism of such events are needed and should characterized in depth.
