E. NFYB binding at hTR promoter in SI14/TEL+, SI24/ALT+, SW39/TEL+ and IMRB/ALT+ cells normalized to H3. Control loci with, respectively, high and low NFYB binding: hnRNPA1 promoter and subtelomeric 4qHox (n=3). Data information: Data are presented as mean ± SD. Statistical analyses were performed with Student's two-tailed unpaired t-test with Welch's correction for normality of distribution unless specified otherwise. PTM, post-translational modification.
