The Gut Microbiota Metabolite Urolithin B Prevents Colorectal Carcinogenesis by Remodeling Microbiota and PD-L1/HLA-B. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2023; 2023:6480848. [PMID: 36778211 PMCID: PMC9908333 DOI: 10.1155/2023/6480848] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/05/2022] [Revised: 12/19/2022] [Accepted: 12/20/2022] [Indexed: 02/05/2023]
Abstract
Colorectal cancer has risen to the third occurring cancer in the world. Fluorouracil (5-Fu), oxaliplatin, and cisplatin are the most effective chemotherapeutic agents for clinical chemotherapy. Nevertheless, due to chemotherapeutic drug resistance, the survival rate of patients with CRC remains very low. In this study, we used the inflammation-induced or mutation-family-inherited murine CRC models to study the anticancer and immunotherapy effects of urolithin B (UB), the final metabolite of polyphenols in the gastrointestinal tract. The label-free proteomics analysis and the gene ontology (GO) classifications were used to test and analyze the proteins affected by UB. And 16S rDNA sequencing and flow cytometry were utilized to uncover gut microbiome composition and immune defense improved by UB administration. The results indicated that urolithin B prevents colorectal carcinogenesis by remodeling gut microbial and tumor immune microenvironments, such as HLA-B, NK cells, regulatory T cells, and γδ TCR cells, and decreasing the PD-L1. The combination of urolithin B with first-line therapeutic drugs improved the colorectal intestinal hematochezia by shaping gut microbiota, providing a strategy for the treatment of immunotherapy treatment for CRC treatments. UB combined with anti-PD-1 antibody could inhibit the growth of colon cancer. Urolithin B may thus contribute to anticancer treatments and provide a high immune response microenvironment for CRC patients' further immunotherapy.

Abstract
Background The aim of this study was to investigate whether carbon-ion beam irradiation in combination with 5-fluorouracil (5-FU) is superior to carbon-ion beam irradiation alone in targeting colorectal cancer stem-like cells (CSCs). Materials and Methods Human colorectal cancer (CRC) cells, HCT116 and HT29, were treated with carbon-ion beam irradiation alone or in combination with 5-FU. Cell viability assay, colony and spheroid formation assay, apoptotic assay, and quantitative real-time PCR analysis of apoptosis- and autophagy-related gene expression were performed. Results Carbon-ion beam irradiation dose-dependently decreased CRC cell viability and showed significantly enhanced cell killing effect when combined with 5-FU. Carbon-ion beam irradiation in combination with 5-FU significantly increased the percentage of apoptotic cells. The expression of some apoptotic and autophagy-related genes such as Bax, Bcl2, Beclin1 and ATG7 was significantly induced by carbon-ion beam irradiation alone and was further enhanced when the beam was combined with 5-FU. The spheroid forming capacity of CD133+ cell subpopulations was significantly inhibited by carbon-ion beam in combination with 5-FU. Histopathologically, the combination of carbon-ion beam irradiation and 5-FU destroyed more xenograft tumor cells, and resulted in increased necrosis, cavitation, and fibrosis, compared to carbon-ion beam irradiation alone. Conclusion In conclusion, carbon-ion beam treatment combined with 5-FU has the potential to kill CRC cells including CSCs by inducing increased apoptosis and autophagy.

Abstract
BACKGROUND There is a strong association between hospital volume and surgical outcomes in resectable colorectal cancer. The purpose of our study was to investigate the association between hospital facility type and survival of patients with metastatic colorectal cancer. METHODS Adults from the National Cancer Database (2010-2015) with a primary diagnosis of colorectal metastases were included and stratified by facility type: community cancer program, comprehensive community cancer program, and academic/research program. The primary outcome was 5-year overall survival, analyzed using Kaplan-Meier survival curves, log-rank test, and the Cox proportional hazards regression model. RESULTS Among the 52,958 included patients, 13.72% were treated at a community cancer program, 49.89% at a comprehensive community cancer program, and 36.29% at an academic/research program. A significant increase in the proportion of patients being treated in an academic/research program has been observed from 2010 to 2015. An academic/research program tended to use more chemotherapy with colorectal radical resection and liver or lung resection and immunotherapy with chemotherapy. In adjusted analysis, the academic/research program had decreased risk of mortality in comparison to the community cancer program and the comprehensive community cancer program (hazard ratio 0.90, 95% confidence interval 0.86-0.94; 0.87, 0.85-0.90; each P < .001; respectively). Similar results were seen after stratifying by metastatic site and treatment type. CONCLUSION The prognosis and overall survival of patients with metastatic disease is better in an academic/research program compared with a community cancer program or a comprehensive community cancer program, with this difference persisting across sites of metastatic disease and treatment types. Further studies are required to validate these results and investigate disparities in the management of metastatic colorectal cancer.

Abstract
There are clinical challenges related to adjuvant treatment in colorectal cancer (CRC) and novel molecular markers are needed for better risk stratification of patients. Our aim was to integrate our previously reported clinical-genetic prognostic score with new immunogenetic markers of 5-year disease-free survival (DFS) to evaluate the recurrence risk stratification before fluoropyrimidine (FL)-based adjuvant therapy. The study population included a total of 270 stage II-III CRC patients treated with adjuvant FL with (FL + OXA, n = 119) or without oxaliplatin (FL, n = 151). Patients were genotyped for a panel of 192 tagging polymorphisms in 34 immune-related genes. The IFNG-rs1861494 polymorphism was associated with worse DFS in the FL + OXA (HR = 2.14, 95%CI 1.13–4.08; P = 0.020, q-value = 0.249) and FL (HR = 1.97, 95%CI 1.00–3.86; P = 0.049) cohorts, according to a dominant model. The integration of IFNG-rs1861494 in our previous clinical genetic multiparametric score of DFS improved the patients’ risk stratification (Log-rank P = 0.0026 in the pooled population). These findings could improve the discrimination of patients who would benefit from adjuvant treatment. In addition, the results may help better elucidate the interplay between the immune system and chemotherapeutics and help determine the efficacy of anti-tumor strategies.

Thymidylate synthase gene variants as predictors of clinical response and toxicity to fluoropyrimidine-based chemotherapy for colorectal cancer. Drug Metab Pers Ther 2018; 32:209-218.

Abstract
BACKGROUND Fluoropyrimidines form the chemotherapy backbone of advanced and metastatic colorectal cancer (CRC). These drugs are frequently associated with toxicity events that result in dose adjustments and even suspension of the treatment. The thymidylate synthase (TYMS) gene is a potential marker of response and toxicity to fluoropyirimidines as this enzyme is the molecular target of these drugs. Our aim was to assess the association between variants of TYMS with response and toxicity to fluoropyrimidines in patients with CRC in independent retrospective and prospective studies. METHODS Variants namely rs45445694, rs183205964, rs2853542 and rs151264360 of TYMS were genotyped in 105 CRC patients and were evaluated to define their association with clinical response and toxicity to fluoropyrimidines. Additionally, the relationship between genotypes and tumor gene expression was analyzed by quantitative polymerase chain reaction. RESULTS The 2R/2R (rs45445694) was associated with clinical response (p=0.05, odds ratio (OR)=3.45) and severe toxicity (p=0.0014, OR=5.21, from pooled data). Expression analysis in tumor tissues suggested a correlation between the 2R/2R genotype and low TYMS expression. CONCLUSIONS The allele 2R (rs45445694) predicts severe toxicity and objective response in advanced CRC patients. In addition, the alleles G(rs2853542) and 6bp-(rs151264360) are independent predictors of response failure to chemotherapy. This is the first study made on a Latin American population that points out TYMS gene variants have predictive values for response and toxicity in patients with CRC treated with fluoropyrimidine-based chemotherapy.

Abstract
OBJECTIVES Life expectancy plays a key role in the selection of patients with stage III colon cancer for adjuvant chemotherapy, but little is known about causes of mortality in older patients with colon cancer. We aimed to examine causes of death in this population and compare these causes between patients who received chemotherapy and those who did not. Specifically, we chose to examine the rates of death related to recurrent colon cancer versus non colon cancer. MATERIALS AND METHODS Patients aged 50 and older diagnosed with stage III colon cancer between 2005 and 2009 were included. Patients were divided into "younger" (aged 50-69) and "older" (aged 70+). Causes of death, which were categorized into colon cancer versus non-colon cancer related. RESULTS 1361 patients were included, 50% of whom were 70 or older. Younger patients were more likely to receive adjuvant chemotherapy (90% vs. 60%). 601 patients died in the follow up period. Deceased patients in the younger group were more likely to die from colon cancer (81% vs. 62%). The most common cause of non-colon cancer death was other primary malignancies in younger patients and cardiovascular diseases in older patients. In older patients who received chemotherapy, 41% died; 89% of these deaths were related to colon cancer. In older patients who did not receive chemotherapy 72% died, with 38% of patients ultimately dying from colon cancer. CONCLUSIONS Older patients remain under-treated with chemotherapy. Although non-colon cancer deaths were more frequent in older patients with cancer, colon cancer was a still a significant cause of mortality. These deaths may be preventable with adjuvant chemotherapy.

Abstract
BACKGROUND Capecitabine and oxaliplatin (CAPOX) and folinic acid, fluorouracil, and oxaliplatin (FOLFOX) are both used in the adjuvant treatment of colon cancer, and while their efficacy is assumed to be similar, they have not been directly compared. We reviewed the toxicity profiles, relative dose intensity (RDI), and survival associated with these regimens across a multi-institutional cohort. PATIENTS AND METHODS We identified 394 consecutively treated patients with stage III colon cancer who received an oxaliplatin-containing regimen. RDI was defined as the total dose received divided by the intended total dose if all cycles were received. RESULTS FOLFOX was associated with increased mucositis (6.2% vs. 0.7%, P = .0069) and neutropenia (25.9% vs. 8.6%, P < .0001), while CAPOX was associated with increased dose-limiting toxicities (DLTs) (90.7% vs. 80.2%, P = .0055), diarrhea (31.8% vs. 9.0%, P < .0001), and hand-foot syndrome (19.9% vs. 2.1%, P < .0001). Higher median RDI of fluoropyrimidine (93.7% vs. 80.0%, P < .0001) and oxaliplatin (87.2% vs. 76.3%, P < .0001) was noted for patients receiving FOLFOX. Reducing the duration from 6 to 3 months would have prevented 28.7% of FOLFOX and 20.5% of CAPOX patients from ever experiencing a DLT (P = .0008). Overall survival did not differ by regimen (hazard ratio = 0.73; 95% confidence interval 0.45-1.22; P = .24). However, CAPOX was associated with improved disease-free survival (3-year disease-free survival 83.8% vs. 73.4%, P = .022), which remained significant in high-risk (T4 or N2) (P = .039) but not low-risk patients (P = .19). CONCLUSION CAPOX may be associated with improved disease-free survival despite greater toxicities and lower RDI. Reducing adjuvant chemotherapy duration to 3 months would prevent 26% of patients from ever experiencing a DLT.

Abstract
The novel proto‑oncogene Golgi phosphoprotein (GOLPH)3 is overexpressed in a variety of tumor tissues and is associated with poor prognosis. The authors previously demonstrated that GOLPH3 gene is overexpressed in colorectal cancer tissues and promotes the proliferation of colonic cancer cells by activating the phosphatidylinositol‑3‑kinase/protein kinase B/the mammalian target of rapamycin and Wnt/β‑catenin signaling pathways. However, to the best of the authors' knowledge, if and how the GOLPH3 gene is involved in inducing resistance to colonic cancer chemotherapy has not been reported. In the present study, the association between the overexpression of the GOLPH3 gene and resistance of HT29 colonic cancer cells to 5‑fluorouracil (5‑FU) was investigated. Following confirmation of the effective silencing of the GOLPH3 gene, proliferation and apoptosis of colonic cancer cells were detected by MTT assay, colony formation assay and flow cytometry, and then the mechanism of GOLPH3‑induced resistance to 5‑FU chemotherapy in colonic cancer cells was investigated by western blotting. The results demonstrated that the expression of phosphorylated (p)‑glycoprotein and GOLPH3 was increased in HT29 cells following treatment with 5‑FU, which resulted in the development of drug resistance. Silencing GOLPH3 increased the sensitivity of HT29 cells to 5‑FU, reduced their tumorigenicity and partly reversed their resistance to 5‑FU. The expression of p‑extracellular signal‑regulated kinase (pERK)1/2 and β‑catenin was decreased, which indicated that its mechanism was associated with the activation of the mitogen‑activated protein kinase/ERK and Wnt/β‑catenin signaling pathways. Therefore, GOLPH3 may be a potential, novel target for reversing chemotherapy resistance in colon cancer.
