Let-7 Family microRNAs Regulate the Expression of the Urokinase-Receptor in Acute Myeloid Leukemia Cells.
Article in Cells, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The urokinase-receptor (uPAR) exerts multiple functions supporting most cancer hallmarks. Increased uPAR expression is associated with an unfavorable prognosis in several cancer types, including hematologic malignancies. We previously reported that three oncosuppressor microRNAs (miRNAs) can target the 3'untranslated region (3'UTR) of the uPAR mRNA and that uPAR mRNA is a competitive endogenous RNA (ceRNA) able to recruit oncosuppressor miRs, thus impairing their activity. We now show that uPAR mRNA can also be targeted by oncosuppressor members of the let-7 miRNA family in acute myeloid leukemia (AML) cell lines. Indeed, let-7a, let7d and let-7g directly target the 3'UTR of uPAR mRNA, thus down-regulating uPAR expression. These let-7 miRNAs are expressed in KG1 and U937 AML cells; their levels are high in KG1 cells, which express low uPAR levels, and low in the U937 cell line, expressing high levels of uPAR. Overexpression of these miRNAs down-regulates uPAR expression and impairs the adhesion to fibronectin and migration of U937 cells, without affecting their proliferation. Accordingly, the overexpression of specific inhibitors targeting these let-7 miRNAs efficiently increases uPAR expression in KG1 cells. These results indicate that selected let-7 miRNAs regulate uPAR expression and impair the adhesion and migration of AML cells.
