Figure 3. HSNFs cannot convert 25VD3 to its biologically active form 1,25VD3. Cells were treated for 24 hours with 25VD3 (20 ng/ml) and 1,25VD3 was subsequently measured in conditioned media. Note that HSNF levels are the same as media alone.

Figure 3

Human sinonasal epithelial cells (HSNEC) can activate 25VD3 to 1,25VD3 and have been included as a positive control. All cells were cultured in serum free media. Mean±SD. *p=0.01 control HSNEC conversion. n=3 patients/group. Statistics shown are result of post hoc analysis following one way ANOVA between indicated groups. NS = not significant.
