After the publication of the above article, the authors have realized that they failed to properly acknowledge the work performed by their Center for Innovative Drug Discovery High Throughput Screening Core Facility in the paper. The Declarations section of their paper should therefore have also included the following statement: "The UT Health San Antonio Center for Innovative Drug Discovery HTS Facility was funded in part by the Cancer Prevention Research Institute of Texas (CPRIT; grant no. RP160844)". The authors regret their oversight in failing to include this information in the Declarations section of their paper. [the original article was published in International Journal of Oncology 53: 2627-2636, 2018; DOI: 10.3892/ijo.2018.4585].
