Recent studies have shown that compared to normal tissues, BCAT2 expression is elevated in cancers such as bladder cancer (Cai et al., 2023), pancreatic cancer (Li et al., 2020; Lee et al., 2019), breast cancer (Zhang and Han, 2017), and non-small cell lung cancer (NSCLC) (Lee et al., 2019). This evidence concerns the gene BCAT2 and non-small cell lung carcinoma.
