The tumor volumes of the xenografts constructed with the NKAPL-overexpressing NSCLC cells were significantly smaller than the volume of those constructed with the control cells (vector) (Fig. 4A, B; Figs. S4A and B), and the NKAPL-overexpressing xenograft tumors weighed less than did those in the vector group (Fig. 4C; Fig. S4C). This evidence concerns the gene NKAPL and neoplasm.
