We crossed IL-6(-/-) mice with Kras(G12D) mutant mice, which develop lung tumors after activation of mutant Kras(G12D), to investigate whether IL-6 inhibition contributes to tumor progression and survival time in vivo.
The concomitant expression of oncogenic Kras(G12D) and mutant p53 (Trp53(R172H)) in the murine pancreas results in metastatic PDA that recapitulates the cognate features of human pancreatic cancer providing an excellent animal model to identify genes required for tumor progression.
