Prognostic evaluation using clinical information obtained from TCGA database and hub genes was conducted to screen for crucial indicators for BC progression.

Functional enrichment analysis showed that DEGs, including ADH1B in cluster 1, were dramatically enriched in the tyrosine and drug metabolism pathways, while genes in cluster 2, including SPP1 and RRM2, played crucial roles in PI3K-Akt and p53 signalling pathway. SPP1 and RRM2 served as hub genes in the PPI network, resulting in an support vector machine classifier with good accuracy and specificity.Ad ditionally, the results of prognostic analysis suggest that age, metastasis stage, SPP1 and ADH1B were correlated with risk of BC, which was validated by using the established risk model analysis.\u0000\u0000Conclusion: SPP1, RRM2 and ADH1B appear to play vital roles in the development of BC.

This article offers a narrative review on physician scientists and endeavours to answer whether there is an ongoing need for physician scientists today. The historical role of physician scientists is discussed and compared with physician scientists of the 21st century. Fundamental differences and similarities between the separate roles of physicians and scientists are examined as well as the current state of bench to bedside research. Finally, the ability of 21st century physician scientists to impact their respective medical and scientific fields in comparison to non-physician scientists will be discussed.

Differential RNAs between HBV-associated HCC and normal controls were identified by a meta-analysis of TCGA, GSE55092 and GSE121248. Weighted gene co-expression network analysis was performed to identify key RNAs and modules. A prognostic score model was established using TCGA as a training set by Cox regression analysis and was validated in E-TABM-36 dataset.
