To further assess the role of TRIM32 in tumorigenicity in vivo, a number of 5 × 106 of NCI-N87 cells that are transfected with siNC or siTRIM32 was hypodermically injected into nude mice (n = 6 for each group) and tumor formation was determined every 3 days for 33 days (starting at day 12). The gene discussed is TRIM32; the disease is neoplasm.
