Aberrant activation of Wnt/β-Catenin signaling pathway drives the expression of poor prognosis-associated microRNAs in adrenocortical cancer with a major impact on miR-139-5p and its host gene PDE2A
Abstract:Adrenocortical carcinoma (ACC) is a rare malignancy with dismal prognosis. Deregulated microRNA (miRNA) expression has been implicated in ACC aggressiveness. Nevertheless, the mechanisms underlying such deregulations remain unknown. Aberrant Wnt/β-Catenin signaling has been reported in about 40% of ACC and is associated with poor outcome. Here, we investigated the link between constitutive activation of Wnt/β-Catenin pathway and miRNA expression alterations in ACC. Inducible shRNA-mediated gene silencing of β-… Show more
