The p38a and p38b MAPK proteins are crucial regulators of bone homeostasis controlling expression and activation of transcription components implicated in osteoblastogenesis like RUNX2. In addition, KSR2 is predicted to mediate PI3K activation. Through PI3K, a RANKL mediated signalling pathway is activated which negatively regulates osteoclast survival. On CFA34, the SNP BICF2P1086886 is located roughly 0.7 Mb downstream from the triple functional domain gene. The protein encoded by TRIO consists of three functional domains, a serine/threonine kinase domain and two guanine nucleotide exchange element domains for the family members of Rho-like GTPases, distinct for Rac1 and RhoA. Rac1 and RhoA act as antagonists, each playing a crucial part in chondrogenic proliferation and differentiation. Chondrocyte-specific deletion of Rac1 in mice leads to dwarfism as a result of decreased chondrocyte proliferation. Inhibition of Rac1 expression in micromass culture resulted in lowered mRNA levels of your chondrogenic markers collagen II and aggrecan, and decreased accumulation of glycosaminoglycans indicating that Rac1 promotes chondrogenesis. Rac1-deficient chondrocytes had severely reduced levels of inducible nitric oxide synthase protein and nitric oxide production. Mice deficient for iNOS had reduced chondrocyte proliferation and resembled the phenotype of Rac1-deficient development plates. RhoA overexpression in chondrogenic ATDC5 cells resulted in enhanced proliferation as well as a marked delay of hypertrophic differentiation, whereas inhibition of Rho/ROCK signaling inhibited chondrocyte proliferation and accelerates hypertrophic differentiation. For that reason, altering the balance between the GTPases RhoA and Rac1 as a consequence of mutations in trio will result in disturbances in cartilage development. In agreement with prior reports, the CHD-associated regions and also the candidate genes identified here, support the important function of enchondral bone formation inside the pathogenesis of CHD. A candidate region identified in German buy PF 4136309 Shepherd Dogs and Labrador Retrievers on CFA8 at 29 Mb harbours the potential candidate gene LRR1. The encoded protein is involved in proteoglycan synthesis by means of NF-kB signalling
