Summary
Caution, this is an AI generated summary based on literature. This may have errors. ?
MIR18A is an oncogenic microRNA whose expression is influenced by the biomechanical properties of the cellular environment in glioma cells [PMC5876527]. Specifically, studies have demonstrated that an increase in matrix stiffness, as well as a higher concentration of fibronectin, correlates with elevated levels of MIR18A expression [PMC5876527]. However, the provided context does not offer information regarding the expression levels of MIR18A within the miR-17-92 cluster or its comparison to miR17, miR19a, and miR20a, and thus no conclusions can be drawn about its relative expression within this cluster [PMC9322280].
