VDR forms heterodimers with one of three RXRs, RXR{alpha}, RXRß, and RXR{gamma}, and it is thought that RXR ligands can also modulate the trans-activation function of VDR/RXR heterodimers. In the present study we generated VDR/RXR{gamma} double null mutant mice to examine the convergent actions of vitamin D and vitamin A signaling and to explore the possibility of a functionally redundant VDR. Although RXR{gamma}-/- mice exhibited no overt abnormalities, VDR-/-/RXR{gamma}-/- mice appeared similar to VDR-/- mice, showing features typical of vitamin D-dependent rickets type II, including growth retardation, impaired bone formation, hypocalcemia, and alopecia. However, compared to VDR-/- mice, growth plate development in VDR-/-/RXR{gamma}-/- mutant mice was more severely impaired. Normalizing mineral ion homeostasis through dietary supplementation with high calcium and phosphorous effectively prevented rachitic abnormalities, except for disarranged growth plates in VDR-/-/RXR{gamma}-/- mutant mice, and alopecia in both VDR-/- and VDR-/-/RXR{gamma}-/- mutant mice. Histological analysis of VDR-/-/RXR{gamma}-/- growth plates revealed that development of the hypertrophic chondrocytes was selectively impaired. Thus, our findings indicated that the combined actions of VDR- and RXR{gamma}-mediated signals are essential for the normal development of growth plate chondrocytes, and raised the possibility that a functionally redundant VDR is present on chondrocytes as a heterodimer with RXR{gamma}.
