Expression of the transgenes
Expression of the transgenes.A, B, Whole cell lysates of bone marrow were subjected to denaturing PAGE and Western blotting using a rabbit polyclonal antihumanRARαF domain antibody. Expression of the transgenes.A, B, Whole cell lysates of bone marrow were subjected to denaturing PAGE and Western blotting using a rabbit polyclonal antihumanRARαF domain antibody. Signals corresponding to transgenically expressed PMLRARα and RARα proteins are indicated by arrows. Locations of size markers are indicated by lines. (A) Protein expression in nonleukemic bone marrow of the highest expressing MRP8-PMLRARα transgenic line (Tg556-PR) and in 2 of the MRP8-PMLRARαm4 mice, Tg4048-PRm4 (nonleukemic bone marrow) and Tg4099-PRm4 (leukemic bone marrow). 8% SDS-polyacrylamide. (B) Protein expression in nonleukemic bone marrow Tg556-PR and in the marrows of healthy MRP8-RARαm4 transgenic mice from 3 lines, Tg4142-Rm4, Tg4151-Rm4, and Tg4192-Rm4. 12% SDS-polyacrylamide. C, Immunofluorescence analysis of bone marrow neutrophilic cells, anti-RARαF antiserum and Hoechst 33258, 1300 × . Scott C. Kogan et al. Blood 2000;95: ©2000 by American Society of Hematology

Variable surface marker expression in PMLRARm4leukemias
Variable surface marker expression in PMLRARm4leukemias.Bone marrow cells were stained with Gr-1 and Mac-1 antibodies that recognize myeloid surface antigens. Variable surface marker expression in PMLRARm4leukemias.Bone marrow cells were stained with Gr-1 and Mac-1 antibodies that recognize myeloid surface antigens. Dead cells were eliminated from the analysis on the basis of staining with propidium iodide. (A) Control. (B) Leukemic mouse 4042 (C) Leukemic mouse 4099 (D) Transplanted leukemia Scott C.

Retinoic acid response of PMLRARm4 leukemias.Leukemic mice were treated with placebo (A, C, E, G, I, K) or tRA (B, D, F, H, J, L). Retinoic acid response of PMLRARm4 leukemias.Leukemic mice were treated with placebo (A, C, E, G, I, K) or tRA (B, D, F, H, J, L). (A-D) PMLRARα expressing leukemia. (E-H)PMLRARαm4 leukemia (I-J) PMLRARαm4 leukemia (K-L) PMLRARαm4 leukemia (A, B, E, F, I-L) Bone marrow, Wright's Giemsa stain, 350 × . (C, D, G, H) Liver, Hematoxylin and eosin stain, 140 × .
