Negative Regulation of Human Pregnane X Receptor by MicroRNA-18a: Evidence for Suppression of MicroRNA-18a Expression by Rifam

Suppression of microRNA-18a expression inhibits invasion and promotes apoptosis of human trophoblast cells by targeting the estrogen receptor α gene.

The purpose of the present study was to gain further understanding of the function of microRNA-18a (miR-18a) expression in the JEG-3 human trophoblast cell line. JEG-3 cells were transfected with pre-miR-18a mimics or miR-18a inhibitors. The effects of miR-18a on trophoblast cell invasion and apoptosis, and on the expression of estrogen receptor α (ESRα) were analyzed using a Transwell invasion...

MicroRNA-18a Attenuates DNA Damage Repair through Suppressing the Expression of Ataxia Telangiectasia Mutated in Colorectal Cancer

BACKGROUND miR-18a is one of the most up-regulated miRNAs in colorectal cancers (CRC) based on miRNA profiling. In this study, we examined the functional significance of miR-18a in CRC. METHODS Expression of miR-18a was investigated in 45 CRC patients. Potential target genes of miR-18a were predicted by in silico search and confirmed by luciferase activity assay and Western blot. DNA damage w...

miR-18a Inhibits CDC42 and Plays a Tumour Suppressor Role in Colorectal Cancer Cells

The miR-17-92 cluster of microRNAs is elevated in colorectal cancer, and has a causative role in cancer development. Of the six miR-17-92 cluster members, miR-19a and b in particular are key promoters of cancer development and cell proliferation, while preliminary evidence suggests that miR-18a may act in opposition to other cluster members to decrease cell proliferation. It was hypothesised th...

MicroRNA-18a inhibits ovarian cancer growth via directly targeting TRIAP1 and IPMK

The role of microRNA-18a (miRNA/miR-18a) as a tumor suppressor or promoter in a number of different types of cancer has been reported. However, to date, the expression and the effects of miR-18a in epithelial ovarian cancer (EOC) remain elusive. In the present study, the expression of miR-18a in patient EOC tissues and ovarian cancer cell lines was investigated using the reverse transcription-q...
