Ref.

In vivo:

↑ trabecular bone mass

↓ decreased osteoclast number and serum NTx In vitro:

↓ osteoclast differentiation

↑ expression of alkaline phosphatase and mineralization in MC3T3-E1 cells

C57BL/6J mice treated with adenovirus expressing lacZ or adiponectin

Treat MC3T3-E1, CD14+ cells, bone marrow macrophage with adiponectin

Micro-CT, EIA (NTx), Histological examination (TRAP+), real-time (ALP), Alizarin Red S staining

[47]

In vivo: No difference between overexpressing adiponectin and WT In vitro:

1.   ↓ osteogenesis in Ad−/− mice bone marrow cell 2. Treat adiponectin recombinant protein inhibit osteogenesis

Ad−/− mice, Ad-Tg mice

Bone marrow cell (from adult mouse long bones, neonatal calvarial osteoblasts, osteoclast precursor M-CSF- dependent bone marrow macrophage, ST2 cells

Histtological analysis, osteoclast formation assay, immunoprecipitation and immunoblotting

[9]

In vivo: ↑ Trabecular bone volume and trabecular number in 14 week Ad KO mice.

In vitro: ↓ osteoclastogenesis in rat and human osteoclast

AdKO mice (C57BL/6J)

Rat and human primary osteoblast, osteoclast

Micro-CT, primary osteoblast culture

[51]

In vivo: ↓ osteoclastogenesis and bone resorption via APPL1-mediated suppression of AKT1 In vitro: ↓ osteoclast differentiation by RANKL in RAW264.7 and decreased expression of osteoclastogenic regulator (NFAT2, TRAF6)

ADN-KO mice

RAW264.7

Histological examination, micro CT
