Figures & data

Figure 1. Vitamin D3 structure and the pathway of its activation and inactivation in body. Vitamin D3 is synthesized from 7-dehydrocholesterol through UVB irradiation in skin. 25-hydroxylase enzyme converts vitamin D3 to 25-hydroxyvitamin D3 in liver. Then, 1α-hydroxylation produces the active vitamin D3(1,25-hydroxyvitamin D3). 25-hydroxyvitamin D3 and 1,25-hydroxyvitamin D3 can be further inactivated into 24,25-hydroxyvitamin D3 and 1,24,25-hydroxyvitamin D3.

Vitamin Dattenuating I/R injuries by suppressing oxidative stress, inflammation, and apoptosis as well as improving proliferation and autophagy. Exogenous vitamin D alsorectified its deficiency and VDRs by improving LncRNA and Klotho levels, which also reduced vicious cycle between I/R injuries and the dysfunctions of vitamin D and VDRs.
