Pamidronic acid，第二代含氮双膦酸盐，是骨丢失抑制剂。Pamidronic acid 通过上调软骨和软骨下骨中 OPG 的表达、并抑制 RANKL 和 MMP-9 在软骨和软骨下骨以及 TLR-4 在软骨中的表达来显著抑制早期骨关节炎的软骨下骨丢失，从而缓解软骨退变。此外 Pamidronic acid 还可以抑制 Wnt 和 β-catenin 的信号传导，能用于骨质酥松症和骨肉瘤的研究。

生物活性

Pamidronic acid, the second-generation nitrogen-containing bisphosphonate, is an inhibitor of bone loss. Pamidronic acid significantly inhibits subchondral bone loss in early osteoarthritis by upregulating the expression of OPG in cartilage and subchondral bone, and inhibiting the expression of RANKL and MMP-9 in both tissues, as well as TLR-4 in cartilage, thereby alleviating cartilage degeneration. Additionally, Pamidronic acid can inhibit the signaling of Wnt and β-catenin, and is applicable for research on osteoporosis and osteosarcoma[1][2][3][4].

Cell Assay
[1]

Cell counts and cell viability assays are performed in cultures of osteosarcoma cells (POS, HMPOS, and COS31 cell lines) and fibroblasts after 24, 48, and 72 hours of incubation with pamidronate at concentrations of 0.001 to 1000 microM or with no drug (control treatment). Percentage viability is determined in cell samples for each concentration of pamidronate and each incubation time. A DNA fragmentation analysis is performed to assess bisphosphonate-induced apoptosis[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
Animal Administration
[3]

Rabbits: The rabbits are randomly divided into four groups. Sham-operated with vehicle treatment, OA induced by ACLT with vehicle treatment, OA-induced ACLT treated with short-term pamidronic acid treatment after ACLT, and ACLT treated with long-term PAM treatment. PAM is injected at the 4th week after ACLT in PAM-S and PAM-L groups, and followed by once monthly ear vein injections at a dosage of 3 mg/kg body weight. In the other groups, only saline infusions of equal volumes are administered. 10 animals are humanely sacrificed at both 2 and 10 weeks after pamidronic acid treatment. In the ACLT and Sham groups, five animals are sacrificed at 2, 4, 6, and 14 weeks after model establishment[3].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
