ALKBH5 and plasma cell leukemia: Furthermore, the dataset GSE39925 [30] showed that ALKBH5 expression was higher in the PCL group than the MM group, but we found that ALKBH5 deletion had a relatively moderate inhibitory effect on the cellular growth of JJN-3, a PCL cell line, compared with the MM cell lines, suggesting that ALKBH5 overexpression might not be the key driver for MM progression to PCL.
