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

backgroundLong non-coding RNAs (LncRNAs) emerging as pivotal marker in the procession of cancer, including colorectal cancer (CRC). Abnormal O-glycosylation is a crucial modification during cancer malignancy. The aim of this work is to analyze the alteration of O-glycosylation involved in CRC progression.

methodsqRT-PCR is utilized to screen the differential linc01296 expression in CRC tissues and cell lines. Functionally, CRC cell proliferation, aggressiveness and apoptosis are measured through relevant experiments, including CCK8 assay, colony formation assay, transwell assay, western blot and flow cytometry. Dual-luciferase reporter gene assay and RIP assay confirm the direct interaction between linc01296 and miR-26a. The xenografts and liver metatstatic nude mice models are established to show the inner effect of linc01296.

resultsDifferential expression of linc01296 is confirmed and closely correlated with the malignancy of CRC cell lines and poor clinical prognosis. Moreover, alteration of linc01296 affects CRC cell proliferation, metastasis and chemoresistance to 5-fluorouracil (5-FU) in vitro. Mechanically, linc01296 acts as a direct target of miR-26a, and thereby influenced CRC malignancy. Our investigation corroborates that linc01296 functions as an endogenous sponge of miR-26a to regulate mucin1 (MUC1) expression, catalyzed by GALNT3, which modulates the activity of PI3K/AKT pathway. Interestingly, upregulated linc01296 promotes the tumorigensis, liver metastasis and chemoresistance of CRC cell lines in vivo.

conclusionThese new findings indicate that linc01296/miR-26a/GALNT3 axis involves in the progression of CRC cells, illuminating the possible mechanism mediated by O-glycosylated MUC1 via PI3K/AKT pathway. This work renders potential diagnostic biomarkers and prospective therapeutic targets for CRC.
