RIT2 and pancreatic insulinoma: There are also GEPNET cell lines derived from transgenic murine rodents, e.g. STC-1 (intestinal NET from SV40-expressing transgenic mouse), βTC and MIN6 (insulinomas from SV40-expressing transgenic mouse), RIN and INS-1 (X-ray induced insulinomas from NEDH rat) (Gazdar et al. 1980, Rindi et al. 1990, Efrat et al. 1991, Asfari et al. 1992, Ishihara et al. 1993).
