(a) Serum calcium, (b) phosphorus and (c) ALP ratio were determined after 4-week administration in vehicle-treated sham-operated mice (Sham), vehicle-treated OVX mice (Control), hPTHrP1-34-treated OVX mice (hPTHrP1-34) and hPTHrP1-84-treated OVX mice (hPTHrP1-84). (d) Western blots of renal extracts for expression of CB28K, CB9K, NCX1 and TRPV5. β-tubulin was used as loading control for Western blots. (e) CB28K, CB9K, NCX1 and TRPV5 protein levels relative to β-tubulin protein level and expressed relative to levels of Sham group. Each value is the mean ± SEM of determinations in six mice of each group.*, P<0.05; ***, P<0.001 compared with Sham group; #, P<0.05 compared with Control group; △, p<0.05 compared with hPTHrP1-34 group.
