Adenomatous polyposis coli (APC) mRNA (APC mRNA)

Adenomatous polyposis coli (APC) mRNA is the transcript of the APC tumor suppressor gene, which is essential for maintaining cellular homeostasis and preventing the initiation of various cancers, most notably colorectal cancer [MedlinePlus, 2025; NIH, 2014]. The primary biological function of the encoded APC protein is to act as a negative regulator of the canonical Wnt signaling pathway by facilitating the degradation of beta-catenin within a multi-protein destruction complex [MedlinePlus, 2025; Wikipedia, 2024]. Mutations in the APC mRNA, particularly those resulting in premature stop codons, lead to the production of truncated, non-functional proteins that fail to regulate beta-catenin, thereby driving uncontrolled cell proliferation and tumorigenesis [MedlinePlus, 2025; ResearchGate, 2010]. Beyond its role in Wnt signaling, APC is involved in cell adhesion, microtubule stabilization, and the maintenance of chromosomal stability [NIH, 2014; Wikipedia, 2024]. As a therapeutic target, APC mRNA is the focus of strategies aimed at restoring functional APC protein levels, such as mRNA replacement therapy using synthetic transcripts or the use of small-molecule read-through agents like aminoglycosides to bypass nonsense mutations [Biorxiv, 2025; NIH, 2011]. Additionally, certain non-steroidal anti-inflammatory drugs (NSAIDs) have been shown to increase APC mRNA expression, suggesting a potential role in chemoprevention [NIH, 2001]. However, the clinical application of these therapies faces significant challenges, including the need for precise delivery to the colonic epithelium and the risk of systemic toxicity or the unintended read-through of natural termination codons [Biorxiv, 2025; ResearchGate, 2010].
