Fig. 5. HOTAIR binds to DNMT1 to regulate PTEN methylation.
A HOTAIR subcellular localization predicted by online analysis site. B HOTAIR distribution in K562 cells and KCL-22 c ells. C HOTAIR distribution in K562 cells and KCL-22 cells verified by FISH assay. D HOTAIR binds to methyltransferase in K562 cells tested by RIP assay. E HOTAIR binds to methyltransferase in KCL-22 cells tested by RIP assay. F The binding of DNMT1 and PTEN in K562 cells tested by ChIP assay. G The binding of DNMT1 and PTEN in KCL-22 cells tested by ChIP assay. H PTEN methylation level in K562 ce lls tested by MSP. I PTEN methylation level in KCL-22 cells tested by MSP. In RIP assay, *P < 0.05 vs. the IgG group. In ChIP assay, *P < 0.05 vs. the sh-NC group. N = 3. Measurement data were depicted as mean ± standard deviation. Comparisons between two groups were conducted by independent sample t-test, and comparison among multiple groups were assessed by one-way ANOVA followed by Tukey’s multiple comparisons test.
