However, data from a total of 83 additional samples in two other ovarian cancer panels revealed a statistically significant, two-fold elevation of STAMP mRNA in tumors of stages I-III relative to "normal" ovarian tissue (n = 13) (Fig. 2B; see Additional file 2: Table S2 for description and grading of samples plus the raw qPCR data). This evidence concerns the gene TTLL5 and ovarian cancer.
