Specific metabolic response of patient-derived organoids to curcumin of colorectal cancer

Organoid is a burgeoning model that have emerged in the past decade. Tumor organoids can simulate specific aspects of the 3D structure, cell type composition and function of real tumors to make up for the deficiencies of cell models and animal models. Curcumin has been found to be effective in suppressing various phases of colorectal cancer development. Nevertheless, there is no clear evidence that the results obtained on cultured cells or animal models can be translated in humans. Therefore, we constructed patient-derived organoids of colorectal cancer to show the curcumin responses of these organoids. Then, a MS-based non-targeted metabolomic strategy was to gain a system-level understanding of the mechanism of curcumin on colorectal cancer patient-derived organoids. Then non-targeted metabonomic analysis found that curcumin mainly regulated the phenylalanine, tyrosine and tryptophan biosynthesis, nicotinate and nicotinamide metabolism, purine metabolism in the organoids of colorectal cancer. Our research provided a reference for further revealing the role of curcumin in human-derived colorectal cancer-like solid tumors.
