GNA13 and renal cell carcinoma: Liu et al. (2017) identified miR-30b-5p as a novel tumour suppressor that regulates renal cell carcinoma cell proliferation, metastasis, and epithelial mesenchymal transition (EMT) by downregulating GNA13 expression. In addition, therapeutic effects have also been reported in gliomas (Qin et al., 2017), inflammatory diseases (Yang et al., 2020), liver cancer (Qin et al., 2017; Zhang et al., 2020), and other diseases.
