(A-D) Cells were obtained from the mice described in figure 2.
(A) mRNA levels of FoxOs by qRT-PCR and protein levels of FoxOs by Western Blot in mature osteoclasts generated from non-adherent bone marrow cells cultured with M-CSF and RANKL for 5 d; ND=not detected.
(B) Caspase 3 activity and (C) mRNA levels of the indicated genes in cells described in A. CtR=calcitonin receptor; CtsK=cathepsin K.
(D) Number of TRAP positive cells generated from bone marrow cells cultured with M-CSF and RANKL for 6 d. TRAP=tartrate-resistant acid phosphatase.
