We expressed EGFP-GRAM-W in U2OS cells (Fig. 4b), macrophages differentiated from THP-1 cells (human monocytes derived from an acute monocytic leukemia patient) (Fig. 4c), N/TERT cells (immortalized keratinocytes derived from fetal foreskin) (Fig. 4d), HEK293T (Fig. 4e), and COS-7 cells (Fig. 4f). Here, TERT is linked to acute monocytic leukemia.
