Fiber and whole grain intakes in relation to liver cancer risk: An analysis in 2 prospective cohorts and systematic review and meta-analysis of prospective studies. Hepatology 2024:01515467-990000000-00778. [PMID: 38441973 DOI: 10.1097/hep.0000000000000819] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/02/2024] [Accepted: 02/07/2024] [Indexed: 03/07/2024]
Abstract
BACKGROUND AND AIMS The association between fiber or whole grain intakes and the risk of liver cancer remains unclear. We assessed the associations between fiber or whole grain intakes and liver cancer risk among 2 prospective studies, and systematically reviewed and meta-analyzed these results with published prospective studies. APPROACH AND RESULTS A total of 111,396 participants from the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial (PLCO) and 26,085 men from the Alpha-Tocopherol, Beta-Carotene Cancer Prevention Study were included. Intakes of total fiber and whole grains were estimated from validated food frequency questionnaires. Study-specific HRs and 95% CI with liver cancer risk were estimated using multivariable-adjusted Cox regression. We systematically reviewed existing literature, and studies were combined in a dose-response meta-analysis. A total of 277 (median follow-up = 15.6 y) and 165 (median follow-up = 16.0 y) cases of liver cancer were observed in Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial and Alpha-Tocopherol, Beta-Carotene Cancer Prevention Study, respectively. Dietary fiber was inversely associated with liver cancer risk in Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial (HR 10g/day : 0.69; 95% CI: 0.55-0.86). No significant associations were observed between whole grain intakes and liver cancer risk in either study. Our meta-analysis included 2383 incident liver cancer cases (7 prospective cohorts) for fiber intake and 1523 cases (5 prospective cohorts) for whole grain intake; combined HRs for liver cancer risk were 0.83 (0.76-0.91) per 10 g/day of fiber and 0.92 (0.85-0.99) per 16 g/day (1 serving) of whole grains. CONCLUSIONS Dietary fiber and whole grains were inversely associated with liver cancer risk. Further research exploring potential mechanisms and different fiber types is needed.

Qi X, Liu L. The regulatory effect of lncRNA LINC00943 on the progression of hepatocellular carcinoma and its relationship with clinicopathological features. Clin Res Hepatol Gastroenterol 2024; 48:102273. [PMID: 38145786 DOI: 10.1016/j.clinre.2023.102273] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Revised: 12/18/2023] [Accepted: 12/22/2023] [Indexed: 12/27/2023]
Abstract
BACKGROUND The risk factors for the pathogenesis of HCC are highly variable, and the prognosis of patients is very unsatisfactory. In this study, we investigated the regulatory effect of LINC00943 on HCC progression and its relationship with clinicopathological features. METHODS LINC00943 level in HCC tissues and cell specimens was verified by RT-qPCR. The pathologic significance of LINC00943 in the prognosis of HCC was analyzed by Kaplan-Meier and Cox regression analyses. The behavioral function of LINC00943 in HCC cells was evaluated via CCK-8 and Transwell assays. The specific targeting relationship between LINC00943 and miR-195-5p was investigated by luciferase activity assay. RESULTS LINC00943 was highly expressed in HCC tissues and cell specimens. Clinical data analysis showed that elevated LINC00943 indicated poor prognosis in patients with HCC and was related to TNM stage and lymph node metastasis. Cell experiments demonstrated that silencing LINC00943 sponge miR-195-5p suppressed the proliferation, migration and invasion of HCC cells. Mechanistically, miR-195-5p inhibitor remedied the suppressive effect of silencing LINC00943 on the biological functions of HCC cells. CONCLUSION LINC00943 may be an independent prognostic factor of HCC, which provides new thinking for the prognosis and treatment of HCC patients.
