LINC00324 targeted miR‐615‐5p/AKT1 axis to promote the tumor process of LUAD.12 LncRNA LINC00460 promoted tumor growth and resulted to a terrible prognosis in LUAD by completely sponging miR‐302c‐5p and upregulating FOXA1 expression.13 Overexpressed SNHG6 in LUAD promoted cell proliferation and metastasis through regulating E2F7 expression and sponging miR‐26a‐5p.14 LOXL1 antisense RNA 1 (LOXL1‐AS1) has been confirmed as an oncogene and its regulatory mechanism in other cancers has been explored. The gene discussed is PTGDR; the disease is neoplasm.
