Differentially expressed RP expression in MDS subsets. (A) MDS versus normal. (B) tMDS versus sMDS. (C) del(5q) versus non del(5q) MDS. (D) Comparative expression of 14 RPs in these MDS subsets. These data demonstrated increased RP expression in MDS versus normal and in tMDS versus sMDS in contrast to their underexpression in del(5q) MDS versus other MDS patients.
