Identification of a 5‑microRNA signature and hub miRNA‑mRNA interactions associated with pancreatic cancer

Abstract: miRNA-gene axes have been reported to serve an important role in the carcinogenesis of pancreatic cancer (PC). The aim of the present study was to systematically identity the microRNA signature and hub molecules, as well as hub miRNA-gene axes, and to explore the potential biomarkers and mechanisms associated with the carcinogenesis of PC. Eleven microRNA profile datasets were obtained from the National Center for Biotechnology Information (NCBI) Gene Expression Omnibus (GEO) and ArrayExpress databases, and a … Show more

“…DNA, RNA, etc.) play an important role in regulating biological functions, 9 network-based approaches, including WGCNA, have been widely used in kidney research and other biomedical studies [12][13][14]28 to capture altered molecular networks and pathways. Once driver modules or pathways are identified, it is crucial to pinpoint key genes for in-depth pathophysiological study and intervention target identification.…”

“…Variable selection has become a routinely used method for identifying relevant biomarkers, 11 and Lasso regression is widely used for binary classifications. 14 The combined use of co-expression network-based analysis and variable selection techniques can be powerful for identifying novel biomarkers and developing predictive models for ESKD risks. Indeed, the predictive model based on the five selected differentially expressed genes showed a strong discrimination power to classify ESKD and controls in the validation dataset.…”

“…High-throughput microarray and RNA sequencing technology, which are able to identify changes in gene expression, have been widely used in studying the etiology of numerous cancer types, including hepatocellular carcinoma (3), breast cancer (4) and pancreatic cancer (5). Screening novel biomarkers for tumor diagnosis and the pathways associated with tumor development, recurrence and drug resistance, are also critical.…”

“…Zhang & Horvath, 2005). Furthermore, WGCNA can be used not only to construct co-expression networks based on coding RNA expression data but also to construct noncoding RNA coexpression networks, such as miRNA co-expression networks and lncRNA co-expression networks (Hu et al, 2019;Ma et al, 2019).…”
