Also PTEN expression was found to present a negative correlation with miR‐17‐5p expression (rs = −0.39, P < 0.05), and it was more lowly‐expressed within CRC cell lines (ie MKN28, MGC‐803, BGC‐823, and SGC‐7901) than within GES‐1 cell line (P < 0.05) (Figure 6B,C). The gene discussed is PTEN; the disease is colorectal carcinoma.
