Previously considered junk or non-functional, long non-coding RNAs (lncRNAs) have emerged over the past few decades as pivotal components in both physiological and pathological processes, including cancer. Neuroblastoma-associated transcript-1 (NBAT-1) was initially discovered a decade ago as a risk-associated tumor suppressor lncRNA in neuroblastoma (NB). Subsequent studies have consistently demonstrated that NBAT-1 serves as a dedicated tumor suppressor in many cancers. NBAT-1 is significantly downregulated in cancer, which is closely linked to higher histological grades, increased metastasis, and poor survival in cancer patients suggesting NBAT-1's potential as a prognostic biomarker. In this review, we delve into the current body of literature, elucidating the tumor-suppressive roles of NBAT-1 and the underlying regulatory mechanisms in the context of human malignancies. Additionally, we shed light on the mechanisms contributing to the diminished expression of NBAT-1 and its potential as both a prognostic biomarker and a promising therapeutic target in cancer.
