Significantly, we observed differential expression of several well-established cancer promoter and suppressor genes, including TP53 (both P < 0.001), PTEN (both P < 0.001), EGFR (both P < 0.001), PIK3CA (both P < 0.001), and KRAS (both P < 0.01), in these cells. This evidence concerns the gene PTEN and cancer.
