Background: Oxidative stress is closely associated with cardiac fibrosis. However, the effect of copper, zinc-superoxide dismutase (SOD1) as a therapeutic agent is limited due to the insufficient transduction. This study was aimed to investigate the effect of PEP-1-SOD1 fusion protein on angiotensin II (ANG II)-induced collagen metabolism in rat cardiac myofibroblasts (MCFs).

Methods: CSCs were treated with VEGF receptor (VEGFR) inhibitors, VCAM-1 antibody (VCAM-1-Ab), or PKC-α inhibitor followed by the treatment with VEGF-A. CSC adhesion assays were performed in vitro.
Objective: To observe the degradation of actin and tubulin in the liver tissue of rats after death and to find an objective indicator of the postmortem interval (PMI).
Methods: Female rats were killed under anesthesia by ether and incubated at 21 degrees C in a temperature controlled system to simulate postmortem changes for 18 days postmortem. Protein in the hepatic tissue was extracted, actin and tubulin were then examined by western blot.
Objective: In order to find a new parameter to estimate the postmortem interval, beta-actin mRNA in lung and thoracic muscle of rats was detected at different time point postmortem.
Methods: Rats were killed by neck dislocation and left in a temperature controlling system at 21 degrees C for 12 days postmortem. Total RNA in lung and thoracic muscle at different time point was extracted and beta-actin mRNA expression was examined by RT-PCR.
