MAFG-AS1, known as MAFG-DT, is found to get involved in several tumors such as bladder cancer (Xiao et al., 2020), colorectal cancer (Ruan et al., 2020), lung cancer (Sui et al., 2019), liver cancer (Chen et al., 2021), ovarian cancer (Bai et al., 2021), breast cancer (Jia et al., 2021), and pancreatic cancer (Ye et al., 2020). This evidence concerns the gene MAFG and urinary bladder carcinoma.
