For example, in osteosarcoma tumour tissues, RGS4 interacts with a noncoding RNA (miR-874-3p) and affects the value-added and migration of cancer cells, and RGS4 overexpression promotes the value-added and migration of human osteosarcoma cells [124] (Figs. 4 and 5, Table 1). Here, RGS4 is linked to cancer.
