CRISPR/Cas9 Screening Highlights PFKFB3 Gene as a Major Contributor to 5-Fluorouracil Resistance in Esophageal Cancer.
Article in Cancers, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundEsophageal cancer (EC) is the eighth most common cancer and the sixth most common cause of death worldwide. Esophageal squamous cell carcinoma (ESCC) comprises the majority of esophageal cancers globally, and 5-Fluorouraci (5-FU) is one of the commonly used chemotherapeutics for this type of cancer. Chemoresistance to drugs is a main obstacle in the successful treatment of this malignancy.
methodsIn this study, we used the CRISPR/Cas9 screening method to determine the target gene related to 5-FU drug resistance in esophageal cancer.
resultsOur research findings indicate that the loss of PFKFB3 can increase the resistance of different human esophageal squamous cell carcinoma cell lines to 5-FU through various pathways. Specifically, in KYSE-70 cells, loss of PFKFB3 can induce epithelial-mesenchymal transition (EMT) and prolong the S phase of the cell cycle, allowing cancer cells to evade the effects of 5-FU and develop resistance. In the KYSE-270 and KYSE-150 cell lines, loss of PFKFB3 can upregulate the expression of Slug and Mcl-1, indirectly regulate Chk1 and promote its autophosphorylation, which in turn inhibits apoptosis, thus counteracting the effects of 5-FU.
conclusionsOur research not only enriches our understanding of the biological characteristics of different ESCC cell lines but also provides new clinical insights for future personalized treatments. Assessing the status of PFKFB3 can help predict resistance to 5-FU in ESCC patients with different genetic backgrounds, allowing for more precise treatment planning. This personalized approach has the potential to improve treatment efficacy, reduce unnecessary drug use and side effects, and ultimately improve patient survival rates and quality of life.
