Abstract
Hepatocyte Nuclear Factor 4-alpha (HNF4α) comprises a nuclear receptor superfamily of ligand-dependent transcription factors that yields twelve isoforms in humans, classified into promoters P1 or P2-associated groups with specific functions. Alterations in HNF4α isoforms have been associated with tumorigenesis. However, the distribution of its isoforms during progression from dysplasia to malignancy has not been studied, nor has it yet been studied in intraductal papillary mucinous neoplasms, where both malignant and pre-malignant forms are routinely clinically identified. We examined the expression patterns of pan-promoter, P1-specific, and P2-specific isoform groups in normal pancreatic components and IPMNs. Pan-promoter, P1 and P2 nuclear expression were weakly positive in normal pancreatic components. Nuclear expression for all isoform groups was increased in low-grade IPMN, high-grade IPMN, and well-differentiated invasive adenocarcinoma. Poorly differentiated invasive components in IPMNs showed loss of all forms of HNF4α. Pan-promoter, and P1-specific HNF4α expression showed shifts in subnuclear and sub-anatomical distribution in IPMN, whereas P2 expression was consistently nuclear. Tumor cells with high-grade dysplasia at the basal interface with the stroma showed reduced expression of P1, while P2 was equally expressed in both components. Additional functional studies are warranted to further explore the mechanisms underlying the spatial and differential distribution of HNF4α isoforms in IPMNs.

Shah SC, Zhu X, Dai Q, Peek RM, Shrubsole MJ. Magnesium intake is associated with a reduced risk of incident liver cancer, based on an analysis of the NIH-American Association of Retired Persons (NIH-AARP) Diet and Health Study prospective cohort. Am J Clin Nutr 2021; 113:630-638.

Abstract
BACKGROUND Liver cancer incidence and mortality are escalating globally. Magnesium intake has been studied extensively in nonmalignant liver pathology, but the association between dietary intake of magnesium and primary liver malignancy has not been previously evaluated. OBJECTIVES We aimed to determine the association between total magnesium intake and primary liver cancer risk. METHODS Using the NIH-American Association of Retired Persons (NIH-AARP) Diet and Health Study prospective cohort, we estimated the association between magnesium intake and the risk of incident primary liver cancer using Cox proportional hazard modeling adjusted for relevant confounders. Comprehensive stratified and sensitivity analyses were performed. RESULTS During 6.4 million person-years of follow-up time, 1067 primary liver cancers occurred in 536,359 participants. Higher magnesium intake was independently associated with a lower risk of liver cancer (P-trend = 0.005), with intakes in the highest compared with lowest quartile associated with 35% lower risk (HR: 0.65; 95% CI: 0.48, 0.87). The dose-related inverse association was more pronounced in moderate and heavy alcohol users (HR: 0.54; 95% CI: 0.35, 0.82; P-trend = 0.006), and this interaction was statistically significant (P-interaction = 0.04). CONCLUSIONS Based on a prospective cohort analysis, we demonstrated that magnesium intake is associated with a lower risk of primary liver cancer, which was more pronounced among moderate and heavy alcohol users. Robust experimental and mechanistic data provide a biological basis to support these findings.
