We additionally evaluated the tumor area of gal 4–KD and scramble-control tumors up to 14 days after transplantation and found that gal 4–KD tumors had significantly smaller tumor areas compared with scramble controls (Fig. 4F), and the gal 4 recurrence observed in the survival experiment (Fig. 4D) was also observed in short-term transplants (Supplementary Fig. S3H). Here, LGALS4 is linked to neoplasm.
