Objective: The objective of this study was to analyze the expression of TARBP1 and its clinical significance in hepatocellular carcinoma (HCC).
Materials And Methods: 90 patients with primary hepatocellular carcinoma were included in this study. The tumor and paired adjacent non-tumor tissues were collected. TARBP1 expression was assessed by quantitative real-time polymerase chain reaction and immunohistochemistry. Associations of TARBP1 expression with the clinicopathological features were analyzed, and prognosis of HCC patients was evaluated.
Results: The result show the expression of TARBP1 mRNA in liver cancer tissues were higher than in the adjacent normal liver tissues in 10 paired samples (P=0.0015). Compared with adjacent normal liver tissues, overexpression of TARBP1 was detected in 61.1% (55/90) HCC patients. TARBP1 expression was associated with the AJCC tumor stage (P=0.004) and clinical stage (P=0.005), and decreased overall survival (P=0.002). In multivariate analysis, TARBP1 expression was an independent prognostic factor for overall survival (Hazard ratio [HR]=2.773, 95% confidence interval [CI] 1.542-4.985; P=0.019).
Conclusions: TARBP1 is up-regulated in HCC, and the expression of TARBP1 was associated with the pathological grading and clinical stage. TARBP1 maybe is an independent prognostic marker of HCC patients.

Neurodegenerative diseases, such as Alzheimer's disease, pose a significant global health challenge with their complex etiology and elusive biomarkers. In this study, we developed the Alzheimer's Identification Tool (AITeQ) using ribonucleic acid-sequencing (RNA-seq), a machine learning (ML) model based on an optimized ensemble algorithm for the identification of Alzheimer's from RNA-seq data. Analysis of RNA-seq data from several studies identified 87 differentially expressed genes.

Cancer cells rely on metabolic reprogramming to sustain the prodigious energetic requirements for rapid growth and proliferation. Glutamine metabolism is frequently dysregulated in cancers and is being exploited as a potential therapeutic target. Using CRISPR/Cas9 interference (CRISPRi) screening, we identified TARBP1 (TAR (HIV-1) RNA Binding Protein 1) as a critical regulator involved in glutamine reliance of cancer cell.

The dynamic balance and distribution of sphingolipid metabolites modulate the level of programmed cell death and plant defence. However, current knowledge is still limited regarding the molecular mechanism underlying the relationship between sphingolipid metabolism and plant defence. In this study, we identified a wheat RNA-binding protein 1 (TaRBP1) and TaRBP1 mRNA accumulation significantly decreased in wheat after infection by Puccinia striiformis f.

The molecular mechanisms underlying hepatocellular carcinoma (HCC) progression remain largely undefined. Here, we identified 176 commonly upregulated genes in HCC tissues based on three Gene Expression Omnibus datasets and The Cancer Genome Atlas (TCGA) cohort. We integrated survival and methylation analyses to further obtain 12 upregulated genes for validation.
