[Retracted] Downregulation of microRNA‑198 suppresses cell proliferation and invasion in retinoblastoma by directly targeting PTEN.

Following the publication of this paper, it was drawn to the Editors' attention by a concerned reader that certain of the data shown for the cell invasion assays in Figs. 2C and 4C were strikingly similar to data appearing in different form in other articles by different authors. Owing to the fact that the contentious data in the above article had already been published elsewhere, or were already under consideration for publication, prior to its submission to , the Editor has decided that this paper should be retracted from the Journal.

miR-340 Exerts Suppressive Effect on Retinoblastoma Progression by Targeting KIF14.

Unlabelled: : This work aimed to investigate the influences of microRNA-340 (miR-340) on proliferation and apoptosis of retinoblastoma (RB) cells and explore its regulatory mechanism.

Materials And Methods: miR-340 mimic and inhibitor were applied for up-regulating or inhibiting the expression of miR-340 in RB cell lines. Then, CCK-8 and AnnexinV-FITC/PI staining were used to measure cell proliferation and apoptosis, respectively.

Downregulation of microRNA‑198 suppresses cell proliferation and invasion in retinoblastoma by directly targeting PTEN.

A number of studies have highlighted that aberrantly expressed microRNAs (miRNAs/miRs) serve crucial roles in the tumorigenesis and tumor development of retinoblastoma (RB). Hence, a full investigation of the biological roles and regulatory mechanisms of miRNAs in RB may provide novel therapeutic targets for patients with this malignancy. miR‑198 is frequently abnormally expressed in various types of human cancers.

Complex three-dimensional polymer-metal core-shell structures towards emission control.

We report the fabrication of three-dimensional periodic metal nickel nanostructures achieved by the combination of femtosecond laser-induced two-photon polymerization and electroless plating technology. We can control the deposition speed of 10 nm per second by adjusting the reaction time. The thermal stability is good under 500 °C for the three-dimensional graphite-lattice polymer structure with 200 nm nickel film.
