Fibronectin 1 Aggravates Colon Cancer Metastasis by Regulating RAP1B Protein Stability Through Akt/CREB Signalling 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
Metastasis is one of the important factors leading to poor prognosis in patients with colon cancer. However, the molecular mechanism contributing to this cellular behaviour remains largely unknown. Here, RNA-seq analysis suggested that Fibronectin 1 (FN1) was significantly increased in metastatic colon cancer, which was associated with poor prognosis. FN1 enhanced colon cancer cell migration, invasion, and epithelial to mesenchymal transition (EMT) in vitro and promoted liver and lung metastasis of colon cancer in nude mice through RAP1B. Mechanistically, FN1 could interact with RAP1B by suppressing the interaction between RAP1B and the E3 ligase PARK2, relieving RAP1B ubiquitination modification and improving RAP1B protein stability. Furthermore, FN1-RAP1B activated Akt signalling pathway, leading to the phosphorylation and activation of CREB. Interestingly, CREB was found directly bound to the FN1 and TIMP1 promoter, respectively and increased FN1 and TIMP1 transcription, thereby establishing a positive regulatory feedback loop. Overall, our results elucidated that FN1 promotes colon cancer migration, invasion, and metastasis. FN1 may be used as the potential therapeutic target for colon cancer metastasis.
