LINC01503 and neoplasm: On the 21st day following inoculation, the tumors were excised, photographed, and weighed after the mice were sacrificed, as shown in Figure 5C. LINC01503 knockdown in MHCC-97H cell line apparently decreased the tumor weight compared with the control group while LINC01503 overexpression in Huh7 cell line showed converse effects (P<0.05) (Figure 5D).
