Zebrafish Lymphoblasts Overexpressing Myc and Bcl-2 Undergo Autophagy (A) Electron microscopic analysis rarely identified autophagosomes in tumor cells from Myc;Cre transgenic fish. Mitochondria are indicated by arrows. (B–D) Thymic lymphoblasts from Myc;Cre;bcl-2 triple-transgenics show prominent autophagosomes/autolysophagosomes. (C) is a magnified view of (B) (box). Arrows indicate double-membrane autophagosomes containing cytoplasm and cytoplasmic organelles. An autolysophagosome is shown in (D) (arrow). (E) Quantification of autophagosomes and autolysophagosomes in Myc;Cre (solid bars) and Myc;Cre;bcl-2 (hatched bars) tumor cells were harvested from three individual fish. From 9 to 15 different cells from each fish were sectioned and analyzed. Mean ± SD results from three individual fish are shown. (F) Western blot analyses of the protein levels of EGFP-zbcl-2, Lc3-I, and Lc3-II in three individual Myc;Cre and Myc;Cre;bcl-2 transgenic fish. Actin was used as a loading control in each lane. Scale bars for (A)–(D), 500 nm. See also Figure S3. |
