Abstract
Background: Acute Liver Failure (ALF) is a difficult problem to solve in clinical practice. The presence of non-SMC condensin I complex subunit G (NCAPG) has previously been linked to vascular invasion of digestive system tumors, foreshadowing poor prognosis. Its role in ALF biology, however, remains unknown. This article explores the role of NCAPG as a potential biomarker candidate for the accurate diagnosis and targeted treatment of ALF.
Methods: The study included transcription data (GSE14668, GSE38941, GSE62029, GSE96851, and GSE120652) of ALF, normal tissues, and clinical samples, where NCAPG was selected as the differential gene by the “DESeq2” R package to analyze the immune cell functions and signal pathways. Furthermore, RT-qPCR and Western blot analyses were used to confirm the RNA and protein levels of NCAPG in ALF cell models, respectively.
Results: Bioinformatics analysis revealed that NACPG was up-regulated in ALF tissues, and the functional signaling pathway was primarily associated with immune infiltration. Based on the results of clinical samples, we suggest that NCAPG was overexpressed in ALF tissues. We also found that the expression of NCAPG increased with the degree of liver injury in vitro. Enrichment analysis suggested that NCAPG influenced ALF as a PI3K/AKT pathway activator.
Conclusion: Our study suggests that NCAPG is a preliminary tool for the diagnosis of ALF. It can affect ALF via the PI3K/AKT pathway and is a potential therapeutic target to improve prognosis.
