CXCR4 Knockdown Via CRISPR/CAS9 in a Tumor-Associated Macrophage Model Decreases Human Breast Cancer Cell Migration.
Article in Cureus, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Introduction Breast cancer is the leading cause of cancer-related deaths in women worldwide with the majority of deaths due to metastasis. The development of metastasis is closely related to the tumor microenvironment where tumor-associated macrophages (TAMs) are the main immune cell component playing a crucial role in tumor migration. Key players in tumor progression, metastasis and survival are the receptor CXCR4 and its ligand CXCL12. CXCR4 is expressed in multiple cell types including macrophages and breast cancer cells. Many studies have focus on the role of CXCR4 expressed in breast cancer cells. Methods In this study, we investigated the role of CXCR4 expressed in TAMs on breast cancer cell migration by reducing CXCR4 expression via CRISPR-CAS9 system in differentiated THP-1 cells (a TAMs model). Results According to wound healing migration assay, MCF7 cancer cells co-cultured with genetically edited dTHP-1 cells have a lower migration rate as compared to MCF7 cancer cells co-cultured with unedited and dTHP-1 cells. Conclusion The study demonstrates the role of CXCR4 on breast cancer cell migration through TAM-cancer cell crosstalk.
