miRNA-144 targeting DNAJC3-AS1 reverses the resistance of the breast cancer cell line Michigan Cancer Foundation-7 to doxorubicin.
Article in Bioengineered, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
This study investigated the role of miRNA-144 (miR-144) targeting of the long noncoding DNAJC3-AS1 in regulating breast cancer chemosensitivity. Real-time quantitative polymerase chain reaction was employed to detect the levels of miR-144 in different drug-resistant cells. MTT assays were used to measure the proliferation of cells in different treatment groups. The apoptosis rate of transfected cells was detected by flow cytometry. Western blotting was used to detect levels of DNAJC3-AS1 protein and of autophagy-related proteins. A double luciferase report experiment was performed to evaluate the targeting effect of miR-144 on DNAJC3-AS1. The level of miR-144 was significantly downregulated in MCF-7 doxorubicin-resistant cells. Upregulated expression of miR-144 increased the doxorubicin sensitivity of drug-resistant cells and the rate of apoptosis. DNAJC3-AS1 was the direct target of miR-144; overexpression of DNAJC3-AS1 significantly rescued the apoptosis induced by miR-144 and reversed the inhibition of autophagy by miR-144. Overexpression of miR-144 can reduce drug resistance in breast cancer cells by inhibiting autophagy or targeting DNAJC3-AS1 for downregulation. miR-144/DNAJC3-AS1 provide a new target for reducing drug resistance in breast cancer.
