For example, lncRNA ABHD11‐AS1 was elevated in PTC, and it augmented the proliferation, migration, and invasion, and suppressed apoptosis of PTC cells by miR‐199a‐5p/SLC1A5 axis.15 The expression of lncRNA AB074169 was decreased in PTC, and overexpression of AB074169 caused cell cycle arrest and inhibited tumor growth.16 LncRNA AB074169 acted as a tumor suppressor in PTC via modulating KHSRP‐mediated CDKN1a expression.16 The gene discussed is CDKN1A; the disease is neoplasm.
