Partial Liver Warm Ischemia-Reperfusion Injury Model

Check if the same lab product or an alternative is used in the 5 most similar protocols
A model of partial liver warm IRI was used (51 (link)). In brief, an atraumatic clip was used to interrupt the arterial and portal venous blood supply to the cephalad lobes of the liver for 90 min. Sham controls underwent the same procedure, but without vascular occlusion. Rapamycin (1-5mg/kg) or Torin 1(10mg/kg), or chloroquine (CQ, 60mg/kg) (Tocris Bioscience, Cambridge, UK) or 3-Methyladenine (3-MA, 30mg/kg), or Triciribine (1mg/kg) (Sigma, St. Luis, MO), were administered, i.p., 1 h prior to the onset of liver ischemia.
Mice were sacrificed after 6h of reperfusion. Serum alanine aminotransferase (sALT) levels were measured by IDEXX Laboratories. Part of liver specimens were fixed in 10% buffered formalin and embedded in paraffin. Liver sections (4μm) were stained with hematoxylin and eosin, and then analyzed blindly. The severity of liver IRI was graded blindly using Suzuki's criteria on a scale from 0 to 4 (52 (link)).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
