LncRNA TTN-AS1 confers tamoxifen resistance in breast cancer via sponging miR-107 to modulate PI3K/AKT signaling pathway.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTamoxifen resistance of breast cancer (BC) is a significant hindrance in clinical therapy. The long-noncoding RNA (lncRNA) TTN-AS1 has been reported as a crucial tumor promoting factor in various cancers. In this study, we set out to discover the specific pathologic regulatory mechanisms of tamoxifen-resistance in breast cancer.
methodsMTT assay was conducted to evaluate the cell viability of the breast cancer cell lines MCF-7 and MCF-7/TAM. QRT-PCR and western blot assay were performed to estimate the expression of TTN-AS1, miR-107 and related proteins. Flow cytometry was conducted to identify degree of apoptosis and cell cycle. The invasive ability was estimated by transwell chamber assay.
resultsOur findings revealed that TTN-AS1 can enhance tamoxifen-resistance in BC cells and augment the invasive ability of tamoxifen-resistant breast cancer cells by down-regulating miR-107, and thereby encourage the development of drug-resistant BC. Further investigation indicates that lncRNA TTN-AS1 worsens the course of tamoxifen-resistant BC by regulating zinc and ring finger 2 (ZNRF2) via miR-107 and activating the PI3K/AKT pathway.
conclusionOur findings suggest that the lncRNA TTN-AS1 can encourage tamoxifen-resistance in BC by modulating the miR-107/ZNRF2 axis and stimulating the PI3K/AKT pathway.
