PTCSC3 and neoplasm: LncRNAs exerting a tumor suppressor functions in PTC are, among the others, NAMA (noncoding RNA associated with MAP kinase pathway and growth arrest) that targets the MAPK signaling pathway [4], PTCSC3 (papillary thyroid carcinoma susceptibility candidate 3) which predisposes to PTC and modulates the expression of several cancer-associated genes [5, 6], and MPPED2-AS1, whose loss of expression is associated with the onset of PTC [7].
