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

backgroundBreast cancer (BC), the most common cause of cancer death in women, overtook lung cancer as the leading cause of cancer worldwide in 2020. Although many studies have proposed KIN17 as a biomarker of tumorigenesis in different cancer types, its role in tumor metastasis, particularly in BC metastasis, has been underexplored. This study aimed to explore the role of KIN17 in BC metastasis.

methodsSurvival analyses was performed to identify the association between KIN17 expression and BC patient survival in silico. Using lentivirus constructs, we developed bidirectional KIN17 expression (KD, knockdown; OE, overexpression) cellular models of luminal-A (Lum-A) breast cancer MCF-7 cells. We performed in vitro wound healing, transwell with and without Matrigel assays, and in vivo tail-vein metastasis assay to evaluate the migration and invasion abilities of MCF-7 with stable KIN17 knockdown or overexpression. Western blotting was performed to compare the changes in protein expression.

resultsWe found that KIN17 expression was associated with poor overall survival (OS), relapse-free survival (RFS), distant metastasis-free survival (DMFS) and post-progression survival (PPS), particularly in Lum-A breast cancer patients. Later, we found that KIN17 knockdown inhibited migration and invasion of MCF-7 cells via regulating EMT-associated signaling pathways in vitro and decreases metastatic spread of the disease in vivo. In contrast, KIN17 overexpression promoted migration and invasion of MCF-7 cells in vitro and increased the metastatic spread of the disease in vivo.

conclusionsOverall, our findings provide preliminary data which suggests KIN17 of importance to target in metastatic Lum-A patients.
