Article Abstract
Introduction: This study combined the bioinformatics and experiment-related technologies to analyze the impact of steroid 5 alpha-reductase 3 (SRD5A3) on the prognosis and immune microenvironment of Liver Hepatocellular Carcinoma (LIHC).
Method: Gene expression and clinical data were obtained from public databases. The prognosis was evaluated using survival, multifactor Cox, enrichment, and mutation analyses. This was then verified through experiments.
Results: The expression level of in LIHC tissues was significantly higher than that in the adjacent tissues. Kaplan-Meier survival analysis showed that high expression was associated with poor overall survival (OS) and short progression-free survival in patients with LIHC. Multivariate Cox regression analysis revealed that positive expression was an independent risk factor for OS in patients with LIHC. Expression of was negatively correlated with immune cell infiltration of CD4+ T, CD8+ T, and B cells. GO and KEGG enrichment analyses showed that was significantly enriched in signaling- and tumor metastasis-related pathways. Nomogram and calibration curve showed that the predicted performance of the model was consistent with the actual results. results confirmed that knockdown inhibited the migration, invasion, and proliferation of LIHC cells.
Conclusions: is actively expressed in LIHC, and positive expression of is an independent risk factor for different prognoses in patients with LIHC. can promote the proliferation, migration, and invasion of liver cancer cells and is related to short immune infiltration in patients with LIHC.

Background: Hepatocellular carcinoma (HCC) prognosis continues to be challenging due to tumor heterogeneity and dynamic immunosuppressive microenvironments. Although pyroptosis plays a critical role in tumor-immune interactions, its prognostic significance in HCC at single-cell resolution has not been systematically investigated.
Methods: We analyzed a publicly available single-cell RNA sequencing (scRNA-seq) data from 10 HCC tumors and paired adjacent tissue samples (60,496 cells) to elucidate pyroptosis-related gene (PRG) profiles.

Liver hepatocellular carcinoma (LIHC) is a prevalent and highly aggressive form of liver cancer, characterized by increasing rates of incidence and mortality globally. Although numerous treatment options currently exist, they frequently result in insufficient clinical outcomes for those diagnosed with LIHC. This highlights the urgent need to identify new biomarkers that can enhance prognostic evaluations and support the development of more effective therapeutic strategies for LIHC.

The overall survival of hepatocellular carcinoma (HCC) remains poor, highlighting the need for better prognostic tools. Nucleotide metabolism fuels tumor progression, while the immune microenvironment dictates therapy response, but integrated models combining both features are lacking. Using TCGA-LIHC transcriptomic/clinical data, we identified nucleotide metabolism and immune-related differentially expressed genes (NMIRGs), which stratified HCC patients into two subtypes via non-negative matrix factorization.

Introduction: The Bystin gene (BYSL) contributes to cancer development and is a probable therapeutic target in cancer therapy. However, no systematic studies have been conducted on BYSL value in pan-cancer diagnosis, prognosis, and immunology.
Methods: We performed a pan-cancer analysis of BYSL using TCGA, GEO, and other databases to assess its expression, clinical significance, genetic variants, methylation, and immune correlation.

Background: Hepatocellular carcinoma (HCC) represents a significant global health concern with persistently high incidence and mortality rates. Immune-related long non-coding RNAs (lncRNAs) may play crucial roles in the pathogenesis and progression of HCC, yet their precise mechanisms remain incompletely elucidated.
Objective: This study aims to explore the potential roles of immune-related lncRNAs in HCC patients through systematic biological approaches, integrating clinical data with bioinformatics analysis, and to construct a COX regression model for predicting patient survival.
