[Retracted] lncRNA ROR promotes the progression of renal cell carcinoma through the miR‑206/VEGF axis.

Following the publication of this paper, it was drawn to the Editor's attention by a concerned reader that certain of the Transwell cell invasion and migration assay data shown in Fig. 2D and F on p. 3786 were strikingly similar to data appearing in different form in other articles written by different authors at different research institutes, which had already been published.

lncRNA ROR promotes the progression of renal cell carcinoma through the miR‑206/VEGF axis.

Renal cell carcinoma (RCC) is the most common kidney malignancy, responsible for ~80% of all cases in adults. The pathogenesis of RCC is complex, involving alterations at both the genetic and epigenetic levels. Numerous signaling pathways, such as PI3K/Akt/mTOR and Wnt‑β‑catenin have been demonstrated to be associated with the tumorigenesis and development of RCC.

The prognostic value of Smad4 mRNA in patients with prostate cancer.

The tumor suppressor gene Smad4 has been localized to chromosome 18q21.1 and is a member of the Smad family that mediates the transforming growth factor β signaling pathway suppressing epithelial cell growth. However, variable expression of Smad4 messenger RNA (mRNA) has been reported, with a loss in some cancers and increased expression in others.
