Abstract Background: The E2F family of transcription factor 2 (E2F2) plays an important role in the development and progression of various tumors, but its association with hepatocellular carcinoma remains unknown. The aim of our study was to investigate the role and clinical significance of E2F2 in hepatocellular carcinoma (HCC).Methods: HCC raw data were extracted from The Cancer Genome Atlas (TCGA). Wilcoxon signed-rank test, Kruskal-Wallis test and logistic regression was applied to analyze the relationship between the expression of E2F2 and clinicopathologic characteristics. Cox regression and Kaplan-Meier was employed to evaluate the correlation between clinicopathologic features and survival. The biological function of E2F2 was annotated by Gene set enrichment analysis (GSEA).Results: The expression of E2F2 was increased in HCC samples. The expression of elevated E2F2 in HCC samples was prominently correlated with histologic grade (OR =2.62 for G3-4 vs. G1-2, p=1.80E-05), clinical stage (OR =1.74 for III-IV vs. I-II, p=0.03), T (OR =1.64 for T3-4 vs.T1-2, p=0.04), tumor status (OR =1.88 for with tumor vs. tumor free, p= 3.79E-03), plasma alpha fetoprotein (AFP) value (OR =3.18 for AFP≥400 vs AFP＜20, p= 2.16E-04; OR=2.50 for 20≤AFP＜400 vs AFP＜20, p=2.56E-03). Increased E2F2 had an unfavorable OS (p=7.468e−05), PFI (p=3.183e−05), DFI (p=0.001), DSS (p=4.172e−05). Elevated E2F2 was independently bound up with OS (p =0.004 , hazard ratio [HR]= 2.4 (95% CI [1.3-4.2])), DFI (P =0.029, hazard ratio [HR] = 2.0 (95% CI [1.1-3.7])) and PFI (P =0.005, hazard ratio [HR] = 2.2 (95% CI [1.3-3.9])) . GSEA disclosed that cell circle, RNA degradation, pyrimidine metabolism, base excision repair, aminoacyl tRNA biosynthesis, DNA replication, p53 signaling pathway, nucleotide excision repair, ubiquitin mediated proteolysis, citrate cycle TCA cycle were notably enriched in E2F2 high expression phenotype.Conclusions: Elevated E2F2 can be a promising independent prognostic biomarker and therapeutic target for HCC. Additionally, cell cycle, pyrimidine metabolism, DNA replication, p53 signaling pathway, ubiquitin mediated proteolysis, the citrate cycle TCA cycle may be the key pathway by which E2F2 participate in the initial and progression of HCC.

Abstract Background Mitochondrial fission regulator 2 (MTFR2) was involved in the progression and development of various cancers. However, the relationship between MTFR2 with lung adenocarcinoma (LUAD) had not been reported. Herein, this study analyzed the clinical significance and potential mechanisms of MTFR2 in LUAD via bioinformatics tools. Results We found that the level of MTFR2 was increased, and correlated with sex, age, smoking history, neoplasm staging, histological subtype and TP53 mutation status in LUAD patients. Kaplan-Meier survival analysis showed LUAD patients with increased MTFR2 had a poor prognosis. In addition, univariate COX regression analysis showed neoplasm staging, T stage, distant metastasis and MTFR2 level were risk factors for the prognosis of LUAD. A total of 1127 genes were coexpressed with MTFR2, including 840 positive and 208 negative related genes. KEGG and GSEA found that MTFR2 participated in the progression of LUAD by affecting cell cycle, DNA replication, homologous recombination, p53 signaling pathway and other mechanisms. The top 10 coexpressed genes, namely CDK1, CDC20, CCNB1, PLK1, CCNA2, AURKB, CCNB2, BUB1B, MAD2L1 and BUB1 were highly expressed, and were associated with poor prognosis in LUAD. Conclusions Consequently, we elucidated MTFR2 was a biomarker for diagnosis and poor prognosis in LUAD, and might participate in the progression of LUAD via affecting cell cycle, DNA replication, homologous recombination and p53 signaling pathway.

However, the relationship between MTFR2 with lung adenocarcinoma (LUAD) had not been reported. Herein, this study analyzed the clinical significance and potential mechanisms of MTFR2 in LUAD via bioinformatic tools.
