Erratum to: Long non-coding RNA ANRIL is upregulated in hepatocellular carcinoma and regulates cell proliferation by epigenetic silencing of KLF2

This article [1] was unintentionally published twice in this journal, by the same authors. The following [1] should be considered the version of record and used for citation purposes: “Huang M-d, Chen W-m, Qi F-z, Xia R, Sun M, Xu T-p, Yin L, Zhang E-b, De W, Shu Y-q, Long non-coding RNA ANRIL is upregulated in hepatocellular carcinoma and regulates cell proliferation by epigenetic silencing of KLF2. Journal of Hematology & Oncology 2015, 8:57 DOI: 10.1186/s13045-015-0153-1”. The duplicate [2]: “Huang M-d, Chen W-m, Qi F-z, Xia R, Sun M, Xu T-p, Yin L, Zhang E-b, De W, Shu Y-q Long non-coding RNA ANRIL is upregulated in hepatocellular carcinoma and regulates cell apoptosis by epigenetic silencing of KLF2. Journal of Hematology & Oncology 2015, 8:50 DOI: 10.1186/s13045-015-0146-0” is to be ignored.
