Abstract

Transforming growth factor beta (TGF‐β), a multifunctional cytokine, plays critical roles in immune responses. However, the precise role of TGF‐β in colitis and colitis‐associated cancer remains poorly defined. Here, it is demonstrated that TGF‐β promotes the colonic inflammation and related tumorigenesis in the absence of Smad family member 4 (Smad4). Smad4 loss in intestinal epithelium aggravates colitis and colitis‐associated neoplasia induced by dextran sulfate sodium (DSS) and azoxymethane/dextran sulfate sodium (AOM/DSS), leading to over‐activated immune responses and increased TGF‐β 1 levels. In Smad4‐deficient organoids, TGF‐β 1 stimulates spheroid formation and impairs intestinal stem cell proliferation and lineage specification. YAP, whose expression is directly upregulated by TGF‐β 1 after Smad4 deletion, mediates the effect of TGF‐β 1 by interacting with Smad2/3. Attenuation of YAP/TAZ prevents TGF‐β 1‐induced spheroid formation in Smad4−/– organoids and alleviates colitis and colitis‐associated cancer in Smad4‐deficient mice. Collectively, these results highlight an integral role of the TGF‐β/Smad4 axis in restraining intestinal inflammation and tumorigenesis and suggest TGF‐β or YAP signaling as therapeutic targets for these gastrointestinal diseases intervention.

  • SMAD4 deletion does not alter Paneth cell numbers during intestinal development in mice.

    “This aligns with prior findings that SMAD4 deletion does not alter Paneth cell numbers during intestinal development in mice, suggesting that SMAD4 is not required for Paneth cell specification.55”

    From Paneth-like transition drives resistance to dual targeting of KRAS and EGFR in colorectal cancer (2026) · cites this paper as [55]

    The Results section reports no significant change in Paneth cell numbers after intestinal epithelial Smad4 deletion. However, the Experimental Section describes inducible deletion in mice generally aged 2–3 months; the paper does not establish the claimed finding during intestinal development. (LLM, conf=0.90)

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.
