We reviewed the literature of these lncRNAs researched in tumors, and found that SAMD12-AS1 could promote gastric cancer progression via DNMT1/P53 axis [24], down-regulate P53 to promote malignant progression of glioma [25], and regulate hepatocellular carcinoma proliferation and apoptosis via the NPM1-HDM2-p53 axis [26], which indicated SAMD12-AS1 could be envisioned as a novel biomarker and therapeutic target for those cancers. The gene discussed is SAMD12; the disease is central nervous system cancer.
