Subsequent studies demonstrate that <em>HITT</em> is increased by several autophagic stimuli, including PI-103, a potent inhibitor of PI3K and mTOR. This is caused by a reduction in the binding between <em>HITT</em> and AGO2, resulting in a reduction in the activity of <em>miR-205</em> towards HITT degradation. Increased <em>HITT</em> then binds to a key autophagy protein, Autophagy-related 5 (ATG5), and inhibits autophagosome formation by preventing the formation of the ATG12-ATG5-ATG16L1 complex.

Several mechanisms, such as the high heme iron content, the formation of N-nitroso compounds (NOCs), heterocyclic amines (HCAs), and polycyclic aromatic hydrocarbons (PAHs), have been suggested to explain red meat's cancer-promoting effects. However, these factors are also found in fish and poultry, which are not linked to CRC risk. A new hypothesis attributes red meat's impact on CRC to its high content of a nonhuman glycan. While most mammals express N-acetylneuraminic acid (Neu5Ac) and N-glycolylneuraminic acid (Neu5Gc), humans express only Neu5Ac due to the loss of the CMAH enzyme. A red meat-rich diet leads to the incorporation of Neu5Gc into human cells, triggering an antibody-mediated inflammatory process known as xenosialitis. This study shows that Neu5Gc incorporation into CRC cells activates the Wnt/β-catenin signaling pathway, promoting cell proliferation. In a murine model lacking CMAH, a Neu5Gc-enriched diet induced intestinal polyp growth, with more malignant characteristics. Additionally, Neu5Gc incorporation in intestinal cells increased the expression of genes downstream of Wnt signaling. These findings reveal, for the first time in an <em>in vivo</em> model, a mechanism independent of immune response, where red meat consumption accelerates tumor progression through Neu5Gc incorporation. This activation of the Wnt/β-catenin signaling pathway provides new insight into how red meat consumption may influence CRC progression.</div></div>","PeriodicalId":9506,"journal":{"name":"Cancer letters","volume":"616 ","pages":"Article 217598"},"PeriodicalIF":9.1,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143536519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rooted in the knowledge that the incidence of cancer correlates strongly with the biological and genetic age, we highlight DNA methylation as a cornerstone of the “epigenetic aging” process with close ties to tumorigenesis. The TME, with its diverse cellular and acellular constituents, is an active participant in tumor biology, further complicated by epigenetic alterations. These modifications, from DNA methylation to histone changes, not only shape the TME but are reciprocally influenced by it, reinforcing a cycle that propels malignancy. Through this exploration, we underline the importance of understanding this mutual relationship, as it holds significant implications for tumor growth, heterogeneity, and therapeutic resistance.

Here, we adapt a translationally relevant model of acute myeloid leukemia (AML) to determine if inflammation in the bone marrow (BM) niche durably reprograms resident healthy HSPCs. To simulate the onset of malignancy and the subsequent remission, we generated hematopoietic chimera composed of healthy HSPCs and HSPCs bearing an inducible oncogenic human MLL-AF9 translocation expression cassette, a validated model of AML. Results show that the exposure to AML blasts in the BM leaves healthy HSPCs with transcriptomic changes and a shift to glycolytic metabolism during experimental remission.
