ARF1 regulates adhesion of MDA-MB-231 invasive breast cancer cells through formation of focal adhesions

Abstract

Adhesion complex formation and disassembly is crucial for maintaining efficient cell movement. During migration, several proteins act in concert to promote remodeling of the actin cytoskeleton and we have previously shown that in highly invasive breast cancer cells, this process is regulated by small GTP-binding proteins of the ADP-ribosylation factor (ARF) family. These are overexpressed and highly activated in these cells. Here, we report that one mechanism by which ARF1 regulates migration is by controlling assembly of focal adhesions. In cells depleted of ARF1, paxillin is no longer colocalized with actin at focal adhesion sites. In addition, we demonstrate that this occurs through the ability of ARF1 to regulate the recruitment of key proteins such as paxillin, talin and FAK to ß1-integrin. Furthermore, we show that the interactions between paxillin and talin together and with FAK are significantly impaired in ARF1 knocked down cells. Our findings also indicate that ARF1 is essential for EGF-mediated phosphorylation of FAK and Src. Finally, we report that ARF1 can be found in complex with key focal adhesion proteins such as ß1-integrin, paxillin, talin and FAK. Together our findings uncover a new mechanism by which ARF1 regulates cell migration and provide this GTPase as a target for the development of new therapeutics in triple negative breast cancer.

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.
