We have been investigating the pancreas specific transcription factor, 1a cre-recombinase; lox-stop-lox- Kristen rat sarcoma, glycine to aspartic acid at the 12 codon (Ptf1a<sup>cre/+</sup>;LSL-Kras<sup>G12D/+</sup>) mouse strain as a model of human pancreatic cancer.
Although the Ptf1a-Cre; LSL-KrasG12D transgenic mouse is perhaps the most widely utilised animal model for human pancreatic cancer, expression levels of HMGA1 in pancreata from this mouse model have not been characterised.
In conditional PCa mouse models with selective in vivo blockade of interleukin (IL)-6 signalling (Ptf1a-Cre;LSL-Kras(G12D)/KC interbred with IL6(-/-) or sgp130(tg) mice), SC reactivity, abdominal mechanosensitivity and spinal glial/neuronal activity were quantified.
Treatment of Ptf1a(cre/+) ;LSL-Kras(G12D/+) ;Tgfbr2(flox/flox) mice with the JNK inhibitor decreased growth of murine pancreatic cancer and prolonged survival of the mice significantly.
