This article is a corrigendum published in the journal Oncology Letters. The authors of the original article contacted the Editorial Office to report errors in the data panels for the cell migration and invasion assay experiments. The Editorial Office conducted an investigation and granted the authors permission to publish a corrigendum. The revised and corrected versions of the figures are included in the corrigendum. The authors apologize for any inconvenience caused. The article focuses on the role of miR-137 in suppressing proliferation, migration, and invasion of colon cancer cell lines by targeting TCF4.

Colorectal cancer is cancer of the colon or rectum and is the third most prevalent form of cancer. Currently, there are several shortcomings in the prognosis and early detection of colon cancer. The present study aims to address questions pertaining to the role of microRNA (miR)‑137 in colon cancer progression and the mode of regulation. The endogenous and over‑expressed levels of miR‑137 in three colon cancer cell lines were assessed by reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR). The MTT assay was used to assess cell proliferation. Cell migration and invasion assays were assessed using Transwell apparatus and Matrigel invasion chambers. The potential targets of miR‑150 were predicted using TargetScan software, and one of the best scoring targets, transcription factor 4 (TCF4), was experimentally validated using western blot analysis and RT‑qPCR. It was found that that miR‑137 is expressed at extremely low levels in COLO205, HCT116 and SW480 cell lines. Cell proliferation, migration and invasion were inhibited subsequent to transfection of the colon cancer cell lines with miR‑137. Using bioinformatics analysis, the best scoring putative targets were identified. One such target, TCF4, was experimentally validated, and it was shown that overexpression of miR‑137 suppresses TCF4 in all three colon cancer cell lines. In conclusion, it was shown that miR‑137 inhibits cell proliferation, migration and invasion in colon cancer cell lines by negatively regulating the expression of TCF4. [ABSTRACT FROM AUTHOR]

The problem of almost disturbance decoupling (ADD) with internal stability is discussed, for a class of high-order cascade nonlinear systems having zero dynamics. Using adding power integrator techniques, the ADD problems via a smooth static state feedback is solved. [ABSTRACT FROM AUTHOR]
