PTP4A3 and neoplasm: PRL-3 expression did not significantly impact tumor initiation, as 7.73–16.68% of animals per clutch developed mCherry-positive nodules by 15 dpf (p≥0.656), and zebrafish developed an average of 1.2 – 1.7 tumors per animal across all groups (p=0.809) (Figure 4A–C, Supplemental Figure 8A–C).
