Four putative miRNA regulatory pairs were discovered: hsa-miR-146b-5p with PHKB and IRAK1, hsa-miR-874-3p with ITGB4 characteristic for cPTC samples, and hsa-miR-152-3p with TGFA characteristic for fvPTC samples. The gene discussed is IRAK1; the disease is follicular variant thyroid gland papillary carcinoma.
