BioMed Research International has retracted this article. This article is one of a series of very similar articles on shRNA and cancer cell lines identified by Byrne and Labbé [2]; the intertextual distance between this article and another of the series [3] is lower than expected by chance. The following concerns were found:(i)The supposed nontargeting control shRNA sequence, 5 GCGGAGGGTTTGAAAGAATATCTCGAGATATTCTTTCAAACCCTCCGCTTTTTT-3, targets TPD52L2 (NM_199360). The same sequence was used as a nontargeting control in other articles identified by Byrne and Labbé. The authors say resequencing showed that the nontargeting sequence plasmid they bought is actually an empty vector.(ii)There is duplication between panels in Figure (a) (between the top left and top right panels and between the bottom left and center left panels), which the authors say was due to carelessness.(iii)The control panels of Figures (a) and (a) in this article are the same as in Figures (a) and (a), respectively, in the authors’ article on Linc-ITGB1 [4], which was not cited. The authors said knockdown of KIAA0125 and Linc-ITGB1 expression by RNAi was performed simultaneously, so they shared the same controls.

Gallbladder cancer (GBC) is one of the mostly aggressive diseases with poor prognosis due to the lack of severe symptoms. To date, little is known about the potential roles and underlying mechanisms of long noncoding RNAs (lncRNAs) in GBC initiation and progression. Thus, it provides us with a novel insight into the contribution of lncRNAs to GBC development. Remarkably, we found the differential expression of a lncRNA, namely, KIAA0125, in a pair of GBC cell sublines which possess different metastatic potentials. Then the effects of KIAA0125 on GBC cell migration, invasion, and epithelial-mesenchymal transitions (EMT) were investigated by using a lentivirus-mediated RNA interference (RNAi) system. Notably, cell migration and invasion were strongly inhibited by KIAA0125 suppression. Moreover, the expression of β-Catenin was increased and the expression of Vimentin was decreased in GBC-SD/M cells after KIAA0125 knockdown. Thus, our findings suggested that KIAA0125 promoted the migration and invasion of GBC cells and could serve as a potential therapeutic target in advanced GBC.
