Also, a recent study revealed that VPS9D1-AS1 promoted the oncogenicity of colorectal cancer cells by acting as a molecular sponge of miR-525-5p and increasing the expression of HMGA1.[26] In lung adenocarcinoma, VPS9D1-AS1 was reported to promote malignant progression by targeting miR-30a-5p/KIF11 axis.[27] AC124854.1 was identified to serve as a prognostic and diagnostic biomarkers for ccRCC.[28] For AL121944.2, AL157935.3, AC007743.1, and AL357992.1, the role of lncRNAs in cancer has not been reported so far. This evidence concerns the gene HMGA1 and lung adenocarcinoma.
