In contrast, SOX11 was absent in the MCL cell line JVM2, the indolent variants of MCL (nine cases), BCR-ABL-positive B-ALLs (the cell line KOPN8 and two primary cases), CLL (three primary cases), FL (two primary cases) and BL (cell line RAJI) (Figure 1D). Here, SOX11 is linked to B-cell chronic lymphocytic leukemia.
