The miRNA profiling of medullary thyroid carcinomas (MTCs) developing in MENX rats identified deregulated miRNAs also found differentially expressed in human hereditary and sporadic MTCs. Functional studies revealed that miR-29 family members and miR-124-3p regulate MTC migration and invasion in MTC cells. Furthermore, the genes
RAB27A and
SPHK1, associated with increased migration and invasion in other cancers, were validated as target genes of miR-124-3p in MTC cells.
SPHK1 showed a differential expression in human MTCs and may thus represent a novel marker of these hereditary tumours.
