TG and thyroid gland carcinoma: We obtained our sporadic thyroid cancer mouse model TgCreERT2;BrafCA/+ by crossing the established BrafCA and TgCreERT2 mouse lines (Dankort et al., 2007; Undeutsch et al., 2014) to conditionally express BRAFV600E in the thyroid under control of the thyroglobulin (Tg) promoter, as previously reported (Charles et al., 2011).
