1 · What the graph read from it

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.

2 · The registry

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

Multidrug resistance (MDR) is one of the primary causes of chemotherapy failure in colorectal cancer (CRC), and extensive biological studies into MDR are required. The non‑coding RNA plasmacytoma variant translocation 1 (PVT1) has been demonstrated to be associated with low survival rates in patients with CRC. However, whether PVT1 serves a critical function in the MDR of CRC remains to be determined. To determine the association between PVT1 expression and 5‑fluorouracil (5‑FU) resistance in CRC, the expression levels of PVT1 mRNA in 5‑FU‑resistant CRC tissues and cell lines (HCT‑8/5‑FU and HCT‑116/5‑FU) were assessed by a reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR). Cytotoxicity was evaluated using a Cell Counting Kit‑8 assay and apoptosis rates were assessed via flow cytometry. In the present study, PVT1 mRNA was highly expressed in 5‑FU‑resistant CRC tissues and cell lines. HCT‑8/5‑FU and HCT‑116/5‑FU cells transfected with small interfering RNA PVT1 and treated with 5‑FU exhibited higher apoptotic rates and lower survival rates. By contrast, overexpression of PVT1 in HCT‑8 and HCT‑116 cells transfected with lentiviral vector‑PVT1‑green fluorescent protein and treated with 5‑FU exhibited lower apoptosis rates and higher survival rates. RT‑qPCR and western blotting demonstrated that the overexpression of PVT1 increased the mRNA and protein expression levels of multidrug resistance‑associated protein 1, P‑glycoprotein, serine/threonine‑protein kinase mTOR and apoptosis regulator Bcl2. The present study indicates that PVT1 overexpression may promote MDR in CRC cells, and suggested that inhibition of PVT1 expression may be an effective therapeutic strategy for reversing MDR in CRC.
