Background: A disintegrin and metalloproteinases (ADAMs) are a novel gene family of proteins that share the metalloproteinase domain with matrix metalloproteinases and have sequence similarities to the reprolysin family of snake venomases (MMPs). They are divided into two classes based on their structural similarities: membrane-anchored ADAM and ADAM with thrombospondin motifs (ADAMTS). These molecules have a role in a number of biological processes, including membrane protein shedding, proteolysis, cell adhesion, cell fusion, and cell migration. Method: In this study, the RNA interaction analysis (miRWalk, lncRRisearch, ENCORI, and lncBase3) and protein interaction analysis (STRING) was performed. Survival, expression, and correlation analyses was performed by ENCORI and GEPIA2. Expression analysis also performed by microarray analysis. GSEA analysis was performed to find top up and down-regulated genes and relevant signaling pathway. Gene ontology analysis was performed by g: Profiler and clusterprofiler. Pathway enrichment was performed by GSEA analysis.ResultsADAMTS5 has a significant low-expression, based on ENCORI (Fold Change: 0.12, FDR < 0.0001), microarray analysis (logFC: -3.791881, adj. P. Val < 0.0001), and qRT-PCR experiment (logFC: -1.975, FC: 0.025, p. value < 0.0001, patients under 40). ADAMTS5 is a potential diagnostic biomarker of BC, based on ROC curve (AUC: 0.75, p. value: 0.0007). mRNA VTI1B, lncRNAs CRNDE and BAIAP2-AS1, and hsa-miR-135a-3b have interaction with ADAMTS5. VTI1B has a significant low-expression (FC: 0.65, FDR: 0.0001). BAIAP2-AS1 is significantly up-regulated (FC: 1.37, FDR: 0.0001). CRNDE is significantly up-regulated (FC: 1.30, FDR: 0.0001). BAIAP2 (log-Rank p: 0.0017, Hazard Ratio: 0.59) and CRNDE (log-Rank p: 0.34, Hazard Ratio: 1.17) are the two potential BC survival predictor.ConclusionIn this study, we performed a differential expression analysis on the expression level of ADAMTS5, VTI1B, and BAIAP2-AS1 in the BC patients for the first time. ADAMTS5 and its correlated oncogene and tumor suppressor RNAs and proteins are the hub therapeutic target of BC. DEGs of the GSE42568 dataset are involve in PPAR and cell cycle checkpoint signaling pathways and during the regulation of mentioned pathway, regulate the BC development. Targeting the expression and interaction of mentioned RNAs can be helpful for the diagnosis, prognosis, and treatment of BC.
