Graphical abstract

This is a correction to: Shijia Bi and others, SIRT7 antagonizes human stem cell aging as a heterochromatin stabilizer, Protein & Cell, Volume 11, Issue 7, July 2020, Pages 483–504, https://doi.org/10.1007/s13238-020-00728-4

The authors wish to introduce the following corrections to their article.

Supplementary Fig. S1F showed the proportion of Ki67 on SIRT7^+/+ and SIRT7^−/− hESCs, where the top representative image was accidentally copied and pasted as the bottom representative image. A new supplementary Fig. S1 is provided below.

Figure S1. Characterization of SIRT7-deficient hESCs. (A) Western blot analysis of SIRT7 protein in young and old primary hMSCs with β-Tubulin used as loading control. (B) Western blot analysis of SIRT7 protein in SIRT7^+/+ and SIRT7^−/− hESCs with β-Tubulin used as loading control. The band corresponding to SIRT7 was indicated with an asterisk. (C) Karyotyping analysis of SIRT7^+/+ and SIRT7^−/− hESCs. (D) Genome-wide analysis of copy number variations (CNVs) in SIRT7^+/+ and SIRT7^−/− hESCs. (E) Immunostaining of OCT4, SOX2, and NANOG and bright-field in SIRT7^+/+ and SIRT7^−/− hESCs. Scale bar, 25 μm. (F) Immunostaining of Ki67 in SIRT7^+/+ and SIRT7^−/− hESCs. Scale bar, 25 μm. Data are presented as the means ± SEM. n = 3. ns, not significant (t test).

In supplementary table (Table S1) for primers, the primers for LINE1 were in wrong order. A new supplementary Table S1 is provided and the primer information is shown below.

These emendations are outlined and provided only in this correction notice to preserve the version of record.
