Older Age Is Associated with Decreased Levels of VDR, CYP27B1, and CYP24A1 and Increased Levels of PTH in Human Parathyroid Glands

Figure 1

The association of (a) VDR, (b) CYP27B1, (c) CYP24A1, and (d) PTH expression levels in human parathydoid glands with age. Quantification of VDR, CYP27B1, CYP24A1, or PTH-positive cell rates in parathyroid glands of patients in different ages was performed by ImageJ software. Scatter plots of expression levels of VDR, CYP27B1, CYP24A1, or PTH versus age were shown.
