Consistently, the clinical correlation between the expression of EZH2, KLF-6, Sp-1, and SNHG6 in patient tumor samples also showed that both EZH2 and Sp-1 displayed the positive correlation with SNHG6, whereas KLF6 and p21 exhibited the negative correlation with SNHG6 (Fig. S2). Here, SNHG6 is linked to neoplasm.
