Bottom-up or Top-down: Inflammation Reprograms Paneth Cells to Develop Bowel Cancers.
The origins of colorectal cancer have long been a subject of intense debate. Early observations noted cancer formation in the human gut slightly above the base of crypts, the structural and functional units of the regenerative compartment of the intestinal epithelium. This suggested that the cells of origin for colorectal cancer reside close to the crypt-villus junction, where more differentiated cells are located. However, the specific induction of early cancer-initiating mutations within differentiated cells failed to initiate cancer. The subsequent identification of long-lived Lgr5+ intestinal stem cells and investigations into their role in cancer development further shifted the earlier views, leading to the widely accepted theory that colorectal cancer arises from stem cells and progenitors located at the base of crypts. A recent study published in Nature Genetics by Mathijs P. Verhagen and colleagues challenges this paradigm, providing compelling evidence that differentiated nonstem cell lineages, particularly Paneth cells, can serve as a source of intestinal tumorigenesis, especially in the context of inflammation and the consumption of a Western-style diet. This work significantly advances our understanding of the colorectal cancer initiation process and provides a new paradigm that may explain the increasingly higher incidence of colorectal cancer in younger people.
期刊介绍:
Cancer Research, published by the American Association for Cancer Research (AACR), is a journal that focuses on impactful original studies, reviews, and opinion pieces relevant to the broad cancer research community. Manuscripts that present conceptual or technological advances leading to insights into cancer biology are particularly sought after. The journal also places emphasis on convergence science, which involves bridging multiple distinct areas of cancer research.
With primary subsections including Cancer Biology, Cancer Immunology, Cancer Metabolism and Molecular Mechanisms, Translational Cancer Biology, Cancer Landscapes, and Convergence Science, Cancer Research has a comprehensive scope. It is published twice a month and has one volume per year, with a print ISSN of 0008-5472 and an online ISSN of 1538-7445.
Cancer Research is abstracted and/or indexed in various databases and platforms, including BIOSIS Previews (R) Database, MEDLINE, Current Contents/Life Sciences, Current Contents/Clinical Medicine, Science Citation Index, Scopus, and Web of Science.
