For example, in 2020, Deyu Liu et al. found that Linc01234 acting as an upstream inhibitor can attenuate the expression of miRNA‐433, thereby resulting in an increase in the expression of PAK4, which plays a pivotal role in promoting the progression of oral cancer,31 which suggested that miRNA‐433 can serve as a potential therapeutic target for oral cancer. Here, PAK4 is linked to lip and oral cavity carcinoma.
