Expression of several osteoclast-specific genes is increased in osteocytes during lactation. (A) Table of microarray data showing significantly changed genes between virgin and lactating animals and between lactating and postlactation animals (*p < 0.05; **p < 0.01; n = 3 per group). (B) Using qPCR, ACP5 (TRAP) mRNA level from isolated osteocytes relative to GAPDH was significantly increased during lactation compared to virgin control or postlactation (*p < 0.05; n = 4 per group). (C) Ctsk (cathepsin K) mRNA level from isolated osteocytes relative to GAPDH was significantly higher during lactation than virgin control or postlactation (*p < 0.05; n = 4 per group).
