Background: RUNX2/CBFA1
Functionally, RUNX2 promotes the expression of osteoblast-specific genes vital for the osteoblast differentiation and proliferation process including type I collagen, osteocalcin (OCN), and alkaline phosphatase (APC) (1, 3). Further evidence for the role of RUNX2 is highlighted by a study of Runx2-/-mice which completely lack osteoblasts (4). Additionally, RUNX2 is also required for chondrocyte maturation, which are the cells responsible for cartilage formation (1, 3, 5). Given the role of RUNX2 in bone and cartilage maturation and formation, it is clear that defects or mutations in RUNX2 cause various bone and bone-related diseases (3, 6, 7). For instance, cleidocranial dysplasia (CCD), which presents with delayed cranial suture closure phenotypes, hypoplastic clavicles, extra teeth, and short stature, is caused by haploinsufficiency in RUNX2 (2, 3, 6). Furthermore, metaphyseal dysplasia with maxillary hypoplasia and brachydactyly (MDMHB) is a bone dysplasia disorder with a phenotype of abnormalities in the long bones, an underdeveloped jawbone, and short fingers that is caused by a duplication in RUNX2 (6). Finally, RUNX2 has been shown to be upregulated in mouse models of the joint disorder osteoarthritis (OA) and may be a potential molecular target for disease treatment (7).
Alternative names for RUNX2 include Acute myeloid leukemia 3 protein CBFA1, CBF-alpha-1, CCD1, CCDAML3, CLCD, Core-binding factor subunit alpha-1, MGC120023, ML3, oncogene AML-3, OSF2, osteoblast-specific transcription factor 2, PEA2aA, PEA2-alpha A, PEBP2A, polyomavirus enhancer-binding protein 2 alpha A subunit, runt related transcription factor 2, SL3/AKV core-binding factor alpha A subunit, and SL3-3 enhancer factor 1 alpha A subunit.
