In GSE1133 [17] dataset that contains two independently obtained expression values for each of 79 different human tissues (Figure 1), the expression profile that corresponds to 209545_s_at probeset demonstrates clear upregulation in CD133-positive myeloid cells, in Burkitt's lymphoma cell line Raji and in smooth muscle, while 209544_at probeset demonstrates more or less uniform expression throughout the spectrum of tissue represented in GSE1133 panel (Figure 1). This evidence concerns the gene PROM1 and Burkitt lymphoma.
