Abstract

Colorectal cancer (CRC) is a leading nonfamilial cause of cancer mortality among men and women. Although various genetic and epigenetic mechanisms have been identified, the full molecular mechanisms deriving CRC tumorigenesis are not fully understood. This study demonstrates that cell adhesion molecule transmembrane and immunoglobulin domain containing 1 (TMIGD1) are highly expressed in mouse and human normal intestinal epithelial cells. TMIGD1 knockout mice were developed, and the loss of TMIGD1 in mice was shown to result in the development of adenomas in small intestine and colon. In addition, the loss of TMIGD1 significantly impaired intestinal epithelium brush border membrane, junctional polarity, and maturation. Mechanistically, TMIGD1 inhibits tumor cell proliferation and cell migration, arrests cell cycle at the G2/M phase, and induces expression of p 21CIP1 (cyclin-dependent kinase inhibitor 1), and p 27KIP1 (cyclin-dependent kinase inhibitor 1B) expression, key cell cycle inhibitor proteins involved in the regulation of the cell cycle. Moreover, TMIGD1 is shown to be progressively down-regulated in sporadic human CRC, and its downregulation correlates with poor overall survival. The findings herein identify TMIGD1 as a novel tumor suppressor gene and provide new insights into the pathogenesis of colorectal cancer and a novel potential therapeutic target.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • TMIGD1 is predominantly expressed by proximal tubule kidney epithelial cells and by intestinal epithelial cells.

    “TMIGD1 is predominantly expressed by proximal tubule kidney epithelial cells23–25 and by intestinal epithelial cells26–28.”
  • Inactivation of the Tmigd1 gene in mice results in a grossly altered morphology of intestinal tissues associated with intestinal adenoma formation and enhanced proliferative activity in intestinal crypts.

    “In further support of a role of TMIGD1 as tumor suppressor, inactivation of the Tmigd1 gene in mice results in a grossly altered morphology of intestinal tissues associated with intestinal adenoma formation and enhanced proliferative activity in intestinal crypts27.”

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.
