Lysophosphatidic acid receptor 4 regulates osteogenic and adipogenic differentiation of progenitor cells via inactivation of RhoA/ROCK1/ β‐catenin signaling

This study has demonstrated that ras homolog family member A (RhoA), along with its major effector, Rho ‐associated kinases 1 (ROCK1) activates β‐catenin signaling to promote osteogenic differentiation and restrain adipogenic differentiation. Lysophosphatidic acid (LPA) receptor 4 (LPAR4), one of the receptors of LPA, blocks the activation of RhoA/ROCK1/β‐catenin signaling pathway, and thereby reciprocally regulates osteogenic and adipogenic differentiation of mesenchymal progenitor cellsin vitro andin vivo. The study suggests the potential of LPAR4 as a pharmaceutical target to treat metabolic disorders such as osteoporosis.
