Identification and analysis of common DEGs and hub genes. (a) Venn diagram depicting the common DEGs across the four datasets filtered based on adjusted p-value of less than 0.05, and log fold change of less than 1. (b) The top five hub genes recognized with highest connectivity identified using the Cytoscape software. (c) Visualization of increased expression of the recognised hub genes in breast and lung cancers, versus normal tissues. ∗ p < 0.05. In the image, BRCA: breast cancer, LUAD: Lung adenocarcinoma; genes expressed in tumours are highlighted in orange, while their expression in normal tissues is depicted in grey. Y-axis represents the expression levels of genes.
