Profilin 1 negatively regulates osteoclast migration in postnatal skeletal growth, remodeling, and homeostasis in mice
2019
ABSTRACT Profilin 1 (Pfn1), a regulator of actin polymerization, controls cell movement in a context‐dependent manner. Pfn1 supports the locomotion of most adherent cells by assisting actin‐filament elongation, as has been shown in skeletal progenitor cells in our previous study. However, because Pfn1 has also been known to inhibit migration of certain cells, including T cells, by suppressing branched‐end elongation of actin filaments, we hypothesized that its roles in osteoclasts may be different from that of osteoblasts. By investigating the osteoclasts in culture, we first verified that Pfn1‐knockdown (KD) enhances bone resorption in preosteoclastic RAW264.7 cells, despite having a compa…
