Nevertheless, vitamin D deficiency could also act during childhood and, indeed, some of the direct data supporting a role of vitamin D in MS pathogenesis actually suggests an effect in childhood or early adulthood [68] [71].
miR856, which may target transcripts from both gene-of-origin (ZAT1) and a novel gene (CHX18), could conceivably fall into this category, although it should be noted that there are no direct data supporting a functional role for miR856.
However, there are no direct data to support this hypothesis in vitro [106], [107].
There are no direct data to support the assertion that certain environmental chemicals bind and activate the thyroid hormone receptors; further research is indicated.
However, since there is no direct data which support this possibility in the present study, further investigation is needed to elucidate this issue.
In summary, the present study provided direct data to support involvement of CA1 in calcification, a key step for bone formation and bone remodeling.
Accordingly, although there are no direct data to support the recommendation that relapsers could be treated with TVR using an RGT approach, the FDA does endorse such a recommendation, as is the case for BOC.
However, as already outlined by Nathan (3), "There are no direct data to support this contention, and no data on glycated hemoglobin are presented, other than in the subgroup that progressed to diabetes, to support a substantial lowering of overall glycemic levels with nateglinide".
Here we provide direct data strongly supporting the hypothesis that cytoplasmic copper levels are increasing in the senescent state.
However, no studies published to date have demonstrated direct experimental data supporting a mechanistic association between hyperinsulinemia and neurodegenerative disorders.
