Calcium Carbonate Suppresses Haem Toxicity Markers without Calcium Phosphate Side Effect on Colon Carcinogenesis [PDF]

, 2010
Red meat intake is associated with increased risk of colorectal cancer. We have previously shown that haemin, haemoglobin and red meat promote carcinogen-induced preneoplastic lesions, aberrant crypt foci, in the colon of rats.

Orthotopic Esophageal Cancer Xenograft Model in Immunosuppressed Microminipigs for Near‐Infrared Fluorescence Endoscopy

Cancer Science, EarlyView.
We report the first successful orthotopic engraftment of human esophageal squamous cell carcinoma in immunosuppressed microminipigs and demonstrate high‐contrast near‐infrared fluorescence endoscopic detection using EGFR‐targeted cetuximab. This large‐animal model bridges preclinical imaging research and future clinical translation in esophageal cancer.

Study of the antineoplastic action of Tabebuia avellanedae in carcinogenesis induced by azoxymethane in mice Estudo da ação antineoplásica da Tabebuia avellanedae (Ipê-Roxo) na carcinogênese induzida pelo azoximetano em camundongos

Acta Cirúrgica Brasileira, 2011
PURPOSE: To study the antitumor action of Tabebuia avellanedae in experimentally induced colon carcinogenesis by azoxymethane in mice. METHODS: Fifty (n=50) mice were divided into five groups: in group I azoxymethane (AOM) was administered, in Group II -

Gut microbiota mediated the toxicity of high concentration of dietary nitrite in C57BL/6 mice

Ecotoxicology and Environmental Safety, 2022
Growing evidence indicates that exposure to high levels of nitrite for a prolonged time has adverse health effects. Although gut microbiota is responsible for the transformation of nitrite in the gut, the evidence concerning whether gut microbiota ...

Energy balance and cancers [PDF]

, 1999
Energy balance results from the exact equilibrium between caloric intake and caloric expenditure. A caloric intake larger than caloric expenditure results in overweight, even obesity, but other determinants, like hormonal dysfunction and/or genetic ...

The Guanylate Cyclase C-cGMP Signaling Axis Opposes Intestinal Epithelial Injury and Neoplasia. [PDF]

, 2018
Guanylate cyclase C (GUCY2C) is a transmembrane receptor expressed on the luminal aspect of the intestinal epithelium. Its ligands include bacterial heat-stable enterotoxins responsible for traveler\u27s diarrhea, the endogenous peptide hormones ...

Colorectal Precancerous Lesions: Molecular Mechanisms, Research Tools, and Natural Product‐Based Clinical Translation

MedComm – Oncology, Volume 5, Issue 2, June 2026.
This article systematically elucidates the molecular mechanisms of colorectal precancerous lesions, introduces cutting‐edge research tools like multi‐omics and organoids, and highlights the potential and prospects of natural products such as berberine, resveratrol, and curcumin in preventing and intervening in colorectal carcinogenesis by modulating ...

Genetic and microbial determinants of azoxymethane-induced colorectal tumor susceptibility in Collaborative Cross mice and their implication in human cancer

Gut Microbes
The insights into interactions between host genetics and gut microbiome (GM) in colorectal tumor susceptibility (CTS) remains lacking. We used Collaborative Cross mouse population model to identify genetic and microbial determinants of Azoxymethane ...

Combination of selenium and green tea improves the efficacy of chemoprevention in a rat colorectal cancer model by modulating genetic and epigenetic biomarkers [PDF]

, 2013
Dietary supplementation of selenium and green tea holds promise in cancer prevention. In this study, we evaluated the efficacies of selenium and green tea administered individually and in combination against colorectal cancer in an azoxymethane (AOM ...

Parvimonas micra promotes carcinogenesis of colorectal cancer through phenyllactic acid‐induced DNA damage

Clinical and Translational Medicine, Volume 16, Issue 5, May 2026.
Multiomics analysis of the faecal samples from CRC patients found that upregulation of P. micra and PLA was associated with the CRC development. PLA from P. micra via pdhD genes could induce DNA damage via AHR signalling pathway to mediate carcinogenesis.
