“…Genome-wide gene expression profiling provides valuable insight into the transcriptional changes that appear during the carcinogenic process beyond what may be obvious from studies evaluating only clinicopathologic characteristics. The investigation of human diseases using a combination of the human genome-wide molecular data and interactome may further provide an important viewpoint for understanding the molecular features of diseases ( Al-Harazi et al, 2016 ; Al-Harazi et al, 2019 ). Here, we used several genome-wide gene expression profiling datasets from human eHCCs and a rat model of early HCC to conduct an integrative analysis.…”

“…A disease subnetwork or module consists of linked genes or proteins that share mutations, biological processes or expression variations which can be related to a specific disease ( Al-Harazi et al, 2016 ). Previous reports indicated that the development of disease-related subnetwork markers is a robust approach that can provide markers with higher accuracy in disease classification in comparison to using individual genes ( Al-Harazi et al, 2016 ; Khunlertgit and Yoon, 2016 ; Al-Harazi et al, 2019 ). Indeed, network-based analysis of gene expression profiling was performed to identify subnetworks and hub genes that are associated with different cancer, including breast cancer ( Khan et al, 2020 ), lung cancer ( Huang et al, 2015 ), ovarian cancer ( Zhang et al, 2013 ), and others and have demonstrated the significance of the method in discovering genes related to development and progression of cancer (28).…”

“…The network-based markers have been shown to be effective in disease classification, (Zhang et al, 2013;Al-Harazi et al, 2016;Al-Harazi et al, 2019;Khan et al, 2020). Several molecular interaction databases, including DIP (Salwinski et al, 2004), BioGRID (Chatr-Aryamontri et al, 2017, HPRD (Mishra et al, 2006), IntAct (Kerrien et al, 2007), BIND (Alfarano et al, 2005), and MINT (Alfarano et al, 2005) databases have been used to construct the PPI network.…”

“…Network-based methodologies are widely used for the prediction of potential candidate genes and in the construction of gene regulatory networks for different diseases (Nair et al, 2014;Dai et al, 2020;Wang et al, 2021). It has been reported that network-based methods are more effective in discovering cancer biomarkers if integrated with omics datasets (Al-Harazi et al, 2016;Cao et al, 2017;Al-Harazi et al, 2019;List et al, 2020). Indeed, our CRC associated 15-subnetwork markers that we identified in this study achieved excellent accuracy in disease classification that was better than that of several well-known colorectal cancer prognostic gene signatures, such as ColoGuideEx (Ågesen et al, 2012), ColoPrint (Tan and Tan, 2011) and Oncotype DX (Clark-Langone et al, 2010) as well as the 24-gene DEGs.…”
