Additionally, a marked decrease in the percentage of GFP+ leukemic cells was noted in the BM, spleen, and PB of the 2nd recipient mice transplanted with AraC- and ADM-treated Psmb10−/− MA9 mouse BM leukemia cells, compared to those receiving Psmb10+/+ MA9 cells (Fig. 4J and K, Supplementary Fig. S3F). Here, PSMB10 is linked to leukemia.
