ARHGDIB and urinary bladder carcinoma: For example, the ATG7 gene, which is overexpressed in invasive bladder cancer tissue, can promote autophagic degradation of the HNRNPD (ARE/poly(U)-binding/degradation factor 1) protein, which, in turn, increases ARHGDIB mRNA stability and bladder cancer cell invasion (Zhu et al., 2019).
