Erratum to: J Gastrointest Oncol 2021;12:2728-42.
In the article that appeared on page: 2728-2742, Vol 12, No 6 (December 2021) issue of Journal of Gastrointestinal Oncology (JGO) (1), some errors were found in figures, tables, methods and author information.
Firstly, the authors accidentally used the incorrect version of the Figure 2C,2D; Figure 3B; Figure 5B,5C, and Figure 6C,6D. The corrected Figure 2C,2D; Figure 3B; Figure 5B,5C and Figure 6C,6D can be found below.
Corrected Figure 2C,2D:
Corrected Figure 3B:
Corrected Figure 5B,5C:
Corrected Figure 6C,6D:
Besides, the authors identified 2 errors in Table 1. The details are as followings:
1st column, 9th row: “Rectum”, needs to be corrected as “Cardia”;
1st column, 10th row: “Colon”, needs to be corrected as “Pylorus”.
The corrected Table 1 is given below (Table 1).

Meanwhile, the authors identified some errors on the Primer sequence for POT1-AS1 and U1, si-POT1-AS sequence, and PDK3 antibody description. The details are as followings:
In the “Cell transfection” section, “Si-POT1-AS1: 5'-UCCCCCCCTGCTGGUCAGAGAC-3'” should be corrected to “Si-POT1-AS1: 5'- GCCUCUUCCAUGGUUUAUATT -3'”.
In the “RT-qPCR” section, “POT1-AS1: F: 5'-AGATCTAGGCTTCGGAAGGAAAAGC-3', R: 5'-CCCAAGATCTAGCGCACCGCCTA-3'” should be corrected to
“POT1-AS1: F: 5'- ATCTTGGCTGGCCATTACCC-3', R: 5'- TGGCATCAAATTGTCCTTGGC-3'”. And “U1 F: 5'-GGCCACACTGACTTCTCAAAAT-3', R: 5'-GGCTGGCACATACTGCGGG-3'” should be corrected to “U1 F: 5'-TGATCACGAAGGTGGTTTTCC-3', R: 5'-GCACATCCGGAGTGCAATG-3'”.
In the “Western blotting (WB)” section, “with mouse anti-human PDK4 (1:1,000; ab182408, Abcam)” should be corrected to “with rabbit anti-human PDK3 (1:1,000; ab182574, Abcam)”.
Finally, there are some mistakes in the authors’ information and their contributions. The mistakes are described as below:
- The order of fourth author and fifth author was incorrect. Yong-Gang Hong should be moved to be the fourth author. Yuan-Ping Tao should be moved to be the fifth author and the superscript "#" of Yuan-Ping Tao should be removed.
- In the third affiliation, “(EHBH)” should be deleted.
- The fourth affiliation and the superscript "4" of Hao Zheng should be deleted.
- There should be only one corresponding author and the correspondence information should be “Correspondence to: Jian-Qing Chen. Department of Gastroenterology, Shidong Hospital, Yangpu District, Shanghai, University of Shanghai for Science and Technology, 999 Shiguang Road, Shanghai 200438, China. Email: cjqing1202@163.com.”
- The author contribution is also corrected as follows:
Contributions: (I) Conception and design: JQ Chen; (II) Administrative support: WM Chen, YM Chen; (III) Provision of study materials or patients: YP Tao, SY Jiang; (IV) Collection and assembly of data: L Yang; (V) Data analysis and interpretation: WM Chen; (VI) Manuscript writing: All authors; (VII) Final approval of manuscript: All authors.
