    ..These results suggest that this gene family plays a wider role in phosphate uptake and remobilisation throughout the plant than was previously believed. ..

    ..Taken together, the results suggest that HORvu;Pht1;1 functions in uptake of phosphate at the root surface, while HORvu;Pht1;6 probably functions in remobilization of stored phosphate from leaves. ..

    ..These results suggest that the mutated protein has a dominant negative effect on the function of ANK, since reduced levels of pyrophosphate in bone matrix are known to increase mineralization. ..

Arthritis Res Ther. 2007;9:R122 pubmed
    ..These data show that TGF-beta1 increases ePPi levels, mainly by the induction of the Ank gene, which requires activation of Ras, Raf-1, ERK, and Ca2+-dependent PKC pathways in chondrocytes. ..
