Recent studies show that DGCR5 plays important roles in various types of cancers in the lung (Chen et al., 2017; Dong et al., 2018; Luo et al., 2018; Wang R. et al., 2018), liver (Wang Y.G. et al., 2018; Wang et al., 2019), stomach (Xu et al., 2019), and bladder (Fang et al., 2019), among others. This evidence concerns the gene DGCR5 and cancer.
