Levels of STAMP mRNA in different human tumor samples. (A) Survey of eight human tumor types. Levels of STAMP mRNA in individual samples of OriGene Tissue Scan panel (each bar corresponds to a single tissue sample) were determined as described in Materials and Methods and plotted (relative to the STAMP mRNA level of the first sample in the Breast panel) vs. tumor stage. (B) STAMP mRNA in human ovarian cancers. Levels of STAMP mRNA in two different large scale OriGene Tissue Scan panels of only ovarian cancers was determined as in A. The data from both panels were combined and plotted (box plot) as percent of the average STAMP level in normal (Stage 0) samples (n = 13) for the different stages (n for Stage IGB [low malignant potential] = 3, Stage I = 12, Stage II = 12, Stage III = 34, Stage IV = 9). P values were determined for ΔCt values from the qRT-PCR assay before conversion to percent of STAMP in normal samples, which was plotted.
