Figure 4. Effect of nicotine on protein expression of CA II, cathepsin K, MMP-9, and V-ATPase d2.

Figure 4

RAW264.7 cells were cultured in differentiation medium with 0 (control), 10−5, 10−4, or 10−3 M nicotine for 5 days. The protein expression of CA II, cathepsin K, MMP-9, and V-ATPase was determined by Western blotting.
