C1GALT1 and neoplasm: We established G292 sublines stably expressing a doxycycline-inducible short hairpin RNA (shRNA) targeting C1GALT1 or a control construct by lentivirus transfection (Supplementary Fig. S2B–D) [18] and compared tumor growth rates following inoculation of NOD/Shi-scid, IL-2Rγ KO Jic (NOG) mice.
