KLF6 alleviates hepatic ischemia-reperfusion injury by inhibiting autophagy.

Hepatic ischemia-reperfusion (I/R) injury, a common clinical complication of liver transplantation, gravely affects patient prognosis. Krüppel-like factors (KLFs) constitute a family of C2/H2 zinc finger DNA-binding proteins. KLF6, a member of the KLF protein family, plays crucial roles in proliferation, metabolism, inflammation, and injury responses; however, its role in HIR is largely remains unknown.

MG132 protects against lung injury following brain death in rats.

Brain death (BD) results in injury to organs and induces lung donor dysfunction. Since the 20S proteasome abnormality is associated with a variety of diseases, the present study investigated whether it was involved in lung injury following BD in rats, and the effects of the proteasome inhibitor MG132 on lung injury was also assessed. Rats were assigned to a BD group or a control sham group.

Effects of chitinase-3-like protein 1 on brain death-induced hepatocyte apoptosis via PAR2-JNK-caspase-3.

Hepatocyte apoptosis is a crucial factor affecting liver quality in brain-dead donors. The identification of key molecular proteins involved in brain-death (BD)-induced hepatocyte apoptosis may help determine an effective method for improving the quality of livers from brain-dead donors. In this study, we used in vivo and in vitro models to investigate the role of chitinase-3-like protein 1 (CHI3L1) in promoting liver cell apoptosis after BD.
