In addition, HMGA1P6 and HMGA1P7 show a similar expression pattern with HMGA1 due to their competition as ceRNAs for the endogenous binding sites of HMGA1-targeting miRNAs; they therefore function as oncogenic regulators of their parental gene HMGA1 in human anaplastic thyroid carcinomas 72. This evidence concerns the gene HMGA1 and thyroid gland undifferentiated (anaplastic) carcinoma.
