Clinical impact of serum transforming growth factor-alpha mRNA as a predictive biomarker for the prognosis of fulminant hepatitis.

ABSTRACT: PURPOSE: We previously reported that measuring serum telomerase reverse transcriptase (hTERT) mRNA with a quantitative, one-step, real-time RT-PCR was superior to conventional tumor markers for hepatocellular carcinoma and lung cancer. Here, we examined serum regeneration-related mRNA detection as a biomarker for fulminant hepatitis (FH). METHODS: In 53 patients, including 17 patients with acute hepatitis (AH), seven with severe hepatitis (SH), four with late-onset hepatic failure (LOHF), and 25 with FH, we measured serum mRNA levels of hTERT, hepatocyte growth factor (HGF), hepatocyte growth factor receptor (c-met), epidermal growth factor receptor (EGFR), and transforming growth factor-alpha (TGF-alpha). We examined the sensitivity and specificity of the technique in FH diagnosis as well as its clinical and prognostic significance compared with other clinical and prognostic tests. RESULTS: Serum copy number of TGF-alpha mRNA in FH on admission was significantly smaller than in AH and SH. In FH, TGF-alpha mRNA level was 10(6)-fold higher in survivors than in patients who died or received liver transplants (P = 0.034), although these patients were not discriminated by other clinical parameters. The sensitivity/specificity for prognosis in FH was 74.3/65.5% for TGF-alpha mRNA. Of four prognostic scoring systems, only logit-lambda was useful for prognosis assessment. CONCLUSIONS: TGF-alpha mRNA is an early predictor of FH outcome and a sensitive biomarker of lower regenerative liver capacity. This assay could help facilitate early therapy choice, such as liver transplantation.

Project description:BackgroundGliomas account for nearly 80% of brain cancers, tending to occur more frequently in men with adverse outcomes. Emerging microRNAs have been positioned as promising predictors for glioma's histological grade and prognosis. However, there have been few studies concerning the sex-biased impacts on the clinical approach for the potential microRNA-4297 (miR-4297).MethodsWe utilized GSE139031micro-RNAs profiling to analyze serum miR-4297 expression in glioma. A total of 114 newly diagnosed glioma patients at the First Affiliated Hospital of Fujian Medical University from January 2017 to February 2021 were recruited and prospectively followed up. The association of miR-4297 levels with glioma grade and prognosis was investigated. Luciferase reporter gene assays and genotype analyses were carried out to explore the potential mechanism of sexually dimorphic miR-4297 in glioma.ResultsSerum miR-4297 levels were notably down-regulated in glioma. Besides, serum miR-4297 levels were positively associated with the high grades, which were exclusively present for females. The positive correlations of miR-4297 with O6-methylguanine-DNA methyltransferase (MGMT) protein and mean platelet volume were also observed in females. IDH-mutant females had decreased miR-4297. Median PFS time for females with miR-4297 ≥ 1.392 was distinctly shorter than those with miR-4297 <1.392 (12.3 months vs. 42.89 months, p = 0.0289). Based on multivariate logistic regression, miR-4297-based equation model was established as FHGRS. AU-ROC analysis revealed FHGRS exhibited a robust performance in predicting high-grade glioma in females (p < 0.001), whereas there was no such relationship in males. Furthermore, the MGMT-3'UTR variant rs7896488 in the specific binding region of miR-4297 was correlated with prognosis.ConclusionOur study uncovers sex-dependent characterization of serum miR-4297 in predicting glioma grade and the relapse risk for female patients, which underscores the clinical benefits of sex-specific analysis in non-coding RNA research.
