WebSep 20, 2024 · In addition, S100A12 administration markedly enhanced the osteoclasts’ bone resorption ability, consistent with their increased expression levels of CTSK and CA2. Blocking RAGE and TLR4 cancelled the effects of S100A12. Our results indicate that S100A12 is a potential therapeutic target for inflammatory osteolysis. WebJun 5, 2024 · In contrast to osteoclasts, MGC-specific markers are less well defined. Under pathological conditions, MGCs express effector molecules that are also present in osteoclasts, such as CTSK and MMP9 (da Costa et al., 2005). CTSK and MMP9 transcripts have also been found to be part of a macrophage multinucleation network in …

WebJul 1, 2004 · The Ctsk-Cre transgene is active in osteoclasts and we have observed recombination of the Phlpp1 allele in osteoclasts using this Cre driver (12). Prior reports demonstrate that Ctsk-Cre drivers ... WebANXA3 downregulation abrogated the expression of osteoclast-specific genes, including Acp5, Mmp9 and Ctsk in osteoclast precursors. Moreover, lentiviral of shRNA against ANXA3 reversed the bone loss in osteoporosis using ovariectomized mice model. Mechanistically, we found that ANXA3 directly bound to RANK and TRAF6 to accelerate …
