Hepatic to pancreatic switch defines a role for hemostatic factors in cellular plasticity in mice.

ABSTRACT: In multiple systems, impaired proteolysis associated with the loss of the hemostatic factor plasminogen (Plg) results in fibrin-dependent defects in tissue repair. However, repair within the liver is known to be defective in Plg-deficient (Plg(o)) mice independent of fibrin clearance and appears to be compromised in part by the poor clearance of necrotic cells. Based on these findings, we examined the hepatic transcriptome after injury in search of transcriptional programs that are sensitive to the Plg/fibrinogen system. To this end, we generated biotinylated cRNA pools from livers of Plg(o) mice and controls before and after a single dose of the hepatotoxin carbon tetrachloride and hybridized them against high-density oligonucleotide arrays. Analysis of the gene expression platform identi
