ZFPM2-AS1: An Oncogenic Long Non-coding RNA in Multiple Cancer Types

Abstract:
Long non-coding RNA (lncRNA) is a novel kind of RNA transcript with lengths greater than 200 nucleotides. Functionally, lncRNAs lack the potential to encode peptides or proteins. Previous studies unveiled that lncRNA participated in numerous physiological and pathological processes, including cancer, aging, and immune responses. Newly discovered long noncoding RNA zinc finger protein, Friend of GATA (FOG) family member 2-antisense 1 (ZFPM2-AS1), located on the 8q23 chromosome, acts as a tumor stimulator in various cancer types, including Breast Cancer (BC), Colorectal Cancer (CRC), Esophageal Squamous Cell Carcinoma (ESCC), Gastric Cancer (GC), glioma, hepatocellular carcinoma (HCC), Lung Adenocarcinoma (LUAD), melanoma, non-small cell lung cancer (NSCLC), Retinoblastoma (RB), Small Cell Lung Cancer (SCLC) and thyroid cancer. Accumulative evidence also elucidated that ZFPM2-AS1 dysregulation was related to tumor proliferative, migratory, invasive, anti-apoptotic, and pro-epithelial-tomesenchymal Transition (EMT) effects, larger tumor volume, higher tumor weight, advanced tumor stage, high rates of lymphatic metastasis, distant metastasis, poor prognosis, histological differentiation, higher TNM (tumor, node, metastases) stage, depth of tumor invasion, reduced overall and disease- free survival, vein invasion, and shorter 5-year overall survival. Mechanistically, ZFPM2-AS1 acted as a ceRNA to play its oncogenic role. Thus, this study summarized the specific mechanisms of the lncRNA ZFPM2-AS1 in the aforementioned cancer types to reveal its novel application in cancer diagnosis, treatment, and prognosis.
