Bcl-2 Promotes Onset but Inhibits the Progression of Myc-Induced T-LBL in Zebrafish (A) Rate of tumor onset in three transgenic zebrafish lines: hsp70-Cre;rag2-EGFP-bcl-2 (Cre;bcl-2) double-transgenic fish (n = 31; green line), rag2-LDL-EGFP-Myc;hsp70-Cre (Myc;Cre) double-transgenic fish (n = 26; blue line), and rag2-LDL-EGFP-Myc;hsp70-Cre;rag2-EGFP-bcl-2 (Myc;Cre;bcl-2) triple-transgenic fish (n = 32; red line). (B) Rate of T-LBL progression to T-ALL in Myc;Cre (n = 13; blue line) versus Myc;Cre;bcl-2 (n = 21; red line) transgenic fish. (C–H) Localized GFP-labeled tumors first arose as T-LBL in Myc;Cre (C; 112-day) and Myc;Cre;bcl-2 (F; 119-day) transgenic fish; widespread dissemination leading to leukemia was seen within 11 weeks after T-LBL onset in Myc;Cre fish (D and ,E), but not in Myc;Cre;bcl-2 triple transgenics (G and H). (I–L) GFP-positive T-LBL tumor cells (n = 5 per group) transplanted into the peritoneum of irradiated wild-type hosts. Tumor cells from the Myc;Cre double-transgenic fish disseminated rapidly (I–J), while those from the Myc;Cre;bcl-2 triple-transgenics remained localized (K and L). Scale bar for (C)–(H) and (I)–(L), 1 mm. See also Figure S1. |
