Abstract

Backgrounds: Approximately 1,000 microRNAs (miRs) are present in the human genome; however, little is known about the regulation of miR transcription. Because miR levels are deregulated in chronic lymphocytic leukemia (CLL) and signal transducer and activator of transcription (STAT)-3 is constitutively activated in CLL, we sought to determine whether STAT3 affects the transcription of miR genes in CLL cells. Methods: We used publically available data from the ENCODE project to identify putative STAT3 binding sites in the promoters of miR genes. Then we transfected CLL cells with STAT3-shRNA or with an empty vector, and to determine which miRs are differentially expressed, we used a miR microarray approach followed by validation of the microarray results for 6 miRs using quantitative real-time polymerase chain reaction (qRT-PCR). Results: We identified putative STAT3 binding sites in 160 promoter regions of 200 miRs, including miR-21, miR-29, and miR-155, whose levels have been reported to be upregulated in CLL. Levels of 72 miRs were downregulated (n = 63) or upregulated (n = 9). qRT-PCR confirmed the array data in 5 of 6 miRs. Conclusions: The presence of activated STAT3 has a profound effect on miR expression in CLL cells.

  • Rozovski et al. identified putative STAT3 binding sites in the promoter region of 160 miRNA genes including MIR21.

    “Rozouski et al. identified putative STAT3 binding sites in the promotor region of 160 miRNA genes including MIR21 [82].”

    From Control Mechanisms of the Tumor Suppressor PDCD4: Expression and Functions (2019) · cites this paper as [82]

    The Results and discussion section reports putative STAT3-binding sites in 160 promoter regions and identifies miR-21 among them. It specifies that those promoters correspond to 200 miR genes, not 160 miRNA genes. (LLM, conf=0.88)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
