Shi et al. examined the translational regulation of high-mobility-group AT-hook 2 (HMGA2) by lethal-7 (let-7) and outlined that the let-7-mediated HMGA2 repression in uterine leiomyosarcoma cell lines led to in vitro uterine leiomyosarcoma cell growth inhibition [40]. Here, HMGA2 is linked to leiomyosarcoma.
