CTSB and follicular variant thyroid gland papillary carcinoma: They identified that epigenetic changes involving five miRNAs (hsa-mir-222, hsa-mir-221, hsa-mir-34a, hsa-mir-214, and hsa-mir-138-2) could be influencing the expression of genes such as BCL2, BCL2L11, PEG3, ALDH1A1, PLA2R1, TFCP2L1, RAB23, TK1, and CTSB, which may play roles in the development of FVPTC.
