Relationship between retinol metabolism and hepatocellular carcinoma: a comprehensive analysis of Mendelian randomization, prognostic characteristic and experiment.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeRetinol metabolism is intricately linked to the occurrence and progression of hepatocellular carcinoma (HCC); however, the precise pathogenic relationship between them remains elusive. The aim of this study was to elucidate the characteristics of retinol metabolism in HCC through Mendelian randomization, prognostic model and experimental validation.
methodsWe used transcriptomic data related to HCC in TCGA and GEO databases for a variety of machine learning, including differential gene expression analysis, functional enrichment analysis, protein-protein network interaction, ceRNA regulatory network, and single-cell sequencing analysis. Mendelian randomization analysis was used to elucidate the causal analysis of retinol metabolism and the occurrence of HCC. Consensus cluster analysis was performed based on 11 retinol metabolism-related genes, and the prognostic model was constructed by Lasso regression and Cox regression analysis. The expression level of RDH16 gene was detected in cell lines and clinical samples, and finally the function of RDH16 gene and its regulatory relationship with miR- 665 were verified by in vitro cell experiments.
resultsDifferentially expressed genes were mainly concentrated in the retinol metabolic pathway. Mendelian randomization analysis showed that decreased retinol metabolic activity was causally associated with the occurrence of HCC. RDH16 gene was significantly lower expressed in HCC, and inhibition of RDH16 gene expression could promote the proliferation, migration and invasion of HCC cells and inhibit cell apoptosis. miR- 665 is an upstream regulator of RDH16 gene, which can inhibit the expression and function of RDH16.
conclusionThe decrease of retinol metabolic activity can promote the occurrence and development of HCC. Targeting retinol metabolic pathway may be a new direction for the treatment of HCC.
