Abstract

The trans-sulfuration enzyme cystathionine-β-synthase (CBS) and its product hydrogen sulfide (H2S) are aberrantly upregulated in colorectal cancers, where they contribute to tumor growth and progression by both autocrine and paracrine mechanisms. However, it is unknown whether the CBS/H2S axis plays a role in colorectal carcinogenesis. Here, we report upregulation of CBS in human biopsies of precancerous adenomatous polyps and show that forced upregulation of CBS in an adenoma-like colonic epithelial cell line is sufficient to induce metabolic and gene expression profiles characteristic of colorectal cancer cells. Differentially expressed metabolites (65 increased and 20 decreased) clustered into the glycolytic pathway, nucleotide sugars, intermediates of the pentose phosphate pathway, and lipogenesis, including primarily phospholipids, sphingolipids, and bile acids. CBS upregulation induced broad changes in the NCM356 cell transcriptome with over 350 differentially expressed genes. These genes overlapped significantly with gene sets related to glycolysis, hypoxia, and a colon cancer cell phenotype, including genes regulated by NF-κB, KRAS, p53, and Wnt signaling, genes downregulated after E-cadherin knockdown, and genes related to increased extracellular matrix, cell adhesion, and epithelial-to-mesenchymal transition. The CBS-induced switch to an anabolic metabolism was associated with increased NCM356 cell bioenergetics, proliferation, invasion through Matrigel, resistance to anoikis, and CBS-dependent tumorigenesis in immunocompromised mice. Genetic ablation of CBS in CBS heterozygous mice (CBS+/−) reduced the number of mutagen-induced aberrant colonic crypt foci. Taken together, these results establish that activation of the CBS/H2S axis promotes colon carcinogenesis. Cancer Res; 77(21); 5741–54. ©2017 AACR.

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.
