Upon stratification of the samples based on tumor grade, YY1 was found significantly upregulated in higher grade samples (Grades 3 and 4, G3–4) compared to lower grade ones (Grades 1 and 2, G1–2), whereas RKIP was significantly downregulated (p = 0.0013 and p = 0.0207, respectively; Figure 4B). The gene discussed is YY1; the disease is neoplasm.
