“…MAGI2‐AS3 promotes cancer progression through colorectal cancer through regulating miR‐3163/TMEM106B axis (Ren, Li, Tang, Li, & Lang, 2020), whereas in non‐small–cell lung cancer and acute myeloid leukemia, MAGI2‐AS3 inhibits tumor progression by upregulating the expression of the tumor suppressor genes PTEN or LRIG1 (Chen et al, 2020; Hao & Yang, 2019) Therefore, its role in pancreatic cancer is unclear. However, in breast cancer, transcriptome sequencing studies have shown that MAGI2‐AS3 is one of the core tumor suppressor lncRNAs in breast cancer (Zhang et al, 2019), and related mechanism studies have shown that it can promote apoptosis by activating the Fas/FasL signaling pathway and inhibit breast cancer cell proliferation (Y. Yang et al, 2018), MAGI2‐AS3 has the potential to be a diagnostic or prognostic marker for patients with breast cancer. However, the molecular mechanism by which MAGI2‐AS3 inhibits breast cancer remains to be studied, which may provide a new strategy for the diagnosis and treatment of breast cancer.…”
