After publication of the original article [1], the authors noticed an error within Figs. 3 and 5: Figures 3a and 5a were inadvertently missed. The full versions of Figs. 3 and 5 have been updated in the original article and can be found below. We would like to apologise for the error and for any inconvenience this may have caused.

Aberrant expression of DNMT 3B in HNSCC cell lines and knockdown of DNMT 3B in A253-5 reversed EMT marker genes. a DNMT 3B protein expression in HNSCC cell lines and its invasive subpopulations. b DNMTs and EMT marker genes protein expression in A253 and its invasive subpopulations (A253-3, A253-5) and A253-5 transfected with siRNA against DNMT 3B (A253-5 si). ** indicated p < 0.01 and *** indicated p < 0.001 as compared with A253-0. ### indicated p < 0.001 as compared with A253-5si

MiRNA 29b mimic targeted DNMT 3B and reversed EMT. a Q-PCR examination of miRNA 29b expression in A253 cells. * indicated p < 0.05 and ** indicated p < 0.01 as compared with A253-0. # indicated that there were no statistically significant between A253-5 and A253-5si (Knockdown of DNMT 3B). b Transfection of miRNA 29b mimic could downregulate DNMT 3B and reverse EMT marker genes in A253-5. c, d Migration and invasion assay. Knockdown DNMT 3B by small interfering RNA or mir-29b mimic could inhibit cell mobility. * indicated p < 0.05, ** indicated p < 0.01 and *** indicated p < 0.001 as compared with A253-5
