Ctsk osteoclast
WebDec 21, 2024 · For example, cathepsin K (Ctsk) has been used as a specific osteoclast marker, and Cre driven by its promoter is widely utilized for osteoclast investigations. However, Ctsk-Cre expression has recently been identified in other cell types, such as osteocytes, periosteal stem cells, and tenocytes. To better understand Ctsk-Cre … WebJan 19, 2024 · LC3 is the key factor for osteoclasts’ actin ring formation, CTSK release and resorption activity [10, 11], which suggests that osteoclast abnormality following S1P knockout is LC3 dependent.

WebJul 26, 2024 · CTSK is an osteoclast-specific cysteine protease involved in bone catabolism . We therefore tested to determine whether CST6 inhibited CTSK activity. An in vitro fluorometric assay showed that CST6 inhibited CTSK in a dose-dependent manner, with a 90% inhibition rate at a dose of 2.5 nM . These data demonstrate that CST6 … WebApr 14, 2024 · Osteoporosis is a disease that is characterised by reduced bone mineral density (BMD) and can be exacerbated by the excessive bone resorption of osteoclasts (OCs). Bioinformatic methods, including functional enrichment and network analysis, can provide information about the underlying molecular mechanisms that participate in the …
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 … WebIntriguingly, Chmp5 Ctsk osteoclasts show elevated levels and activation of Src and increases in the activation of the downstream effectors Syk and active GTP-bound Rac1 (Fig. 2, G–I). In keeping with these observations, actin ring formation was enhanced in Chmp5 Ctsk osteoclasts . Thus, CHMP5 coordinately regulates several aspects of ...

Moreover, lentiviral of shRNA against … WebOsteoclast-specific Syk deficiency reduced, whereas hematopoietic Syk deficiency completely blocked in vitro development of osteoclasts. ... As a first approach, we crossed mice in which the cDNA of the Cre recombinase has been inserted into the osteoclast-specific Ctsk gene (referred to as Ctsk Cre/+ or Ctsk-Cre mice) with mice carrying a ...
WebFeb 27, 2024 · The upregulation of Zeb1 expression was confirmed by real‐time PCR and coincides with that of other well‐known osteoclast maturation makers, including Acp5 and Ctsk (Fig 1C). Similarly, at the protein level, Zeb1 content increases as BMDMs are induced to form osteoclasts (Fig 1D; Appendix Fig S1A).

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 … picture of green mangoWebFeb 12, 2016 · The LysM promoter is active in monocytes, macrophages, and osteoclast precursors, whereas the Ctsk promoter was thought to be active only in mature osteoclasts.
