Nephronectin promotes breast cancer brain metastatic colonization via its integrin-binding domains.
Article in Scientific reports, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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 demonstrates a role for the extracellular matrix protein nephronectin (NPNT) in promoting experimental breast cancer brain metastasis, possibly through enhanced binding to- and migration through brain endothelial cells. With the introduction of more targeted breast cancer treatments, a prolonged survival has resulted during the last decade. Consequently, an increased number of patients develop metastasis in the brain, a challenging organ to treat. We recently reported that NPNT was highly expressed in primary breast cancer and associated with unfavourable prognosis. The current study addresses our hypothesis that NPNT promotes brain metastases through its integrin-binding motifs. SAGE-sequencing revealed that NPNT was significantly up-regulated in human breast cancer tissue compared to pair-matched normal breast tissue. Human brain metastatic breast cancers expressed both NPNT and its receptor, integrin α8β1. Using an open access repository; BreastMark, we found a correlation between high NPNT mRNA levels and poor prognosis for patients with the luminal B subtype. The 66cl4 mouse cell line was used for expression of wild-type and mutant NPNT, which is unable to bind α8β1. Using an in vivo model of brain metastatic colonization, 66cl4-NPNT cells showed an increased ability to form metastatic lesions compared to cells with mutant NPNT, possibly through reduced endothelial adhesion and transmigration.
