To confirm whether the BCL6-PLAAT4 axis plays the same role in vivo as that in vitro, we established a subcutaneous transplantation tumor and abdominal metastasis model of the SKOV3 cells in nude mice following replenishment of either BCL6 gene or co-replenishment of both BCL6 and PLAAT4. Here, PLAAT4 is linked to neoplasm.
