IL2RG and familial pancreatic carcinoma: We first performed subcutaneous xenotransplantation of a human pancreatic cancer cell line, MIA-PaCa-2 [65], into ZZU001 hamsters, and for comparisons, also into immunodeficient B-NDG (NOD-Prkdcscid IL2rgtm1/Bcgen) mice which are defective in both the IL2rg gene and the Prkdc gene.
