Downregulation of Chromosome 19 miRNA Cluster and the Tumor‐Suppressive Role of miR‐517a‐3p in Choriocarcinoma

Cancer Science, Volume 116, Issue 12, Page 3473-3486, December 2025.
Chromosome 19 microRNA cluster was downregulated in choriocarcinoma compared with complete hydatidiform mole. miR‐517a‐3p reduced the proliferation, migration, and invasion abilities of choriocarcinoma cell lines. Downregulation of SRSF1, targeted by miR‐517a‐3p, suppressed the malignant potential of choriocarcinoma cell lines. ABSTRACT Choriocarcinoma
