Loss of tissue specificity and recurrent pan-cancer activation define a conserved oncogenic microRNA class (opens in new tab)

MicroRNAs (miRNAs) act as crucial post-transcriptional regulators of large gene networks, and their aberrant expression drives key oncogenic processes such as epithelial-mesenchymal transition (EMT), angiogenesis, immune evasion, and metastasis. Oncogenic miRNAs that lose tissue specificity during malignant transformation represent promising therapeutic targets, as their restricted expression in healthy organs could minimize off-target effects. To identify these candidates, this study perform...
