Mislocalization of the Cell Polarity Protein Scribble Promotes Mammary Tumorigenesis and Is Associated with Basal Breast Cancer
Open accessPublished version of a preprint
Abstract
Scribble (SCRIB) localizes to cell–cell junctions and regulates establishment of epithelial cell polarity. Loss of expression of SCRIB functions as a tumor suppressor in Drosophila and mammals; conversely, overexpression of SCRIB promotes epithelial differentiation in mammals. Here, we report that SCRIB is frequently amplified, mRNA overexpressed, and protein is mislocalized from cell–cell junctions in human breast cancers. High levels of SCRIB mRNA are associated with poor clinical prognosis, identifying an unexpected role for SCRIB in breast cancer. We find that transgenic mice expressing a SCRIB mutant [Pro 305 to Leu (P305L)] that fails to localize to cell–cell junctions, under the control of the mouse mammary tumor virus long terminal repeat promoter, develop multifocal hyperplasia that progresses to highly pleomorphic and poorly differentiated tumors with basal characteristics. SCRIB interacts with phosphatase and tensin homolog (PTEN) and the expression of P305L, but not wild-type SCRIB, promotes an increase in PTEN levels in the cytosol. Overexpression of P305L, but not wild-type SCRIB, activates the Akt/mTOR/S6K signaling pathway. Human breast tumors overexpressing SCRIB have high levels of S6K but do not harbor mutations in PTEN or PIK3CA, identifying SCRIB amplification as a mechanism of activating PI3K signaling in tumors without mutations in PIK3CA or PTEN. Thus, we demonstrate that high levels of mislocalized SCRIB functions as a neomorph to promote mammary tumorigenesis by affecting subcellular localization of PTEN and activating an Akt/mTOR/S6kinase signaling pathway.

“hSCRIB protein is mislocalized from cell-cell junctions in multiple human cancers, including breast, prostate and colon (2, 3).”
§ Mislocalization of the cell polarity protein Scribble promotes mammary tumorigenesis and is associated with basal breast cancer > Introduction
What the sources say
- Partly supportedcites [2] Zhan, 2008, Deregulation of Scribble promotes mammary tumorigenesis and reveals a role for cell polarity in carcinoma, Cell sourceExperimental — accuracy not yet measured
The Results sections on human breast cancer cell lines and primary breast cancers report Scribble mislocalization away from cell-cell junctions, including in 10 of 20 DCIS samples. The passages do not establish the same finding for prostate cancer; the cited colon work appears in the References, but these passages do not establish junctional mislocalization in colon cancer. (LLM, conf=0.87)
- Partly supportedcites [3] Pearson, 2011, SCRIB expression is deregulated in human prostate cancer, and its deficiency in mice promotes prostate neoplasia, J Clin Invest sourceExperimental — accuracy not yet measured
The Introduction and Discussion state that SCRIB is mislocalized in human colorectal and breast cancers, and the Results report mislocalization in human prostate cancer. But the Results and Figure 6 description classify one prostate pattern as clustering at cell-cell junctions, so the source does not support the more specific claim that mislocalization is always away from those junctions. Page numbers are not available in our copy. (LLM, conf=0.86)

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.
A language model drew the claims from the paper on 2026-09-30, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-09-30 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
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.
