Runt-related transcription factor-3 (RUNX3) is primarily involved in cartilage mineralization and chondrocyte maturation, though evidence suggests that miRNA-regulated RUNX3 is capable of influencing phosphatidylinositol-3-kinase protein kinase B (PI3K/AKT) signaling pathway, which is crucial for cancer cell proliferation [123,124,125]. The gene discussed is RUNX3; the disease is cancer.
