Abstract

Prompted by the ever-growing scientific rationale for examining the antidiabetic drug metformin as a potential antitumor agent in breast cancer disease, we recently tested the hypothesis that the assessment of metformin-induced global changes in gene expression-as identified using 44 K (double density) Agilent's whole human genome arrays-could reveal gene-expression signatures that would allow proper selection of breast cancer patients who should be considered for metformin-based clinical trials. Using Database for Annotation, Visualization and Integrated Discovery bioinformatics (DAVID) resources we herein reveal that, at doses that lead to activation of the AMP-activated protein kinase (AMPK), metformin not only downregulates genes coding for ribosomal proteins (i.e., protein and macromolecule biosynthesis) but unexpectedly suppresses numerous mitosis-related gene families including kinesins, tubulins, histones, auroras and polo-like kinases. This is, to our knowledge, the first genome-scale evidence of a mitotic core component in the transcriptional response of human breast cancer cells to metformin. These findings further support a tight relationship between the activation status of AMPK and the chromosomal and cytoskeletal checkpoints of cell mitosis at the transcriptional level.

  • Metformin may selectively kill cancer stem cells and enhance effectiveness of breast cancer treatment regimens.

    “Other in vitro studies suggest that metformin may selectively kill cancer stem cells and enhance effectiveness of breast cancer treatment regimens (85–87).”

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.
