... [3,5-7]. In spite of all, clinical trials using gene or protein therapy with VEGF isoforms for treatment of myocardial or peripheral ischemia have been somewhat disappointing indicating the needs ... analysis in the ischemic hindlimb as well as by histology in wounds and Matrigel plugs. Our findings show the proangiogenic properties of QK, suggesting that also in vivo this p...

Thus, in the context of the func- tional link between the htid encoded proteins and ErbB-2 in the present study we addressed the question whether in human sporadic breast tumors the in vivo expression profiles ... thus, demonstrating the inverse correlation of the expression of the two tumor relevant molecules and implying their functional link. Discussion The...

... from these compounds being taken up into the cell and incorporated into vital haem proteins instead of haem [5]. We show here that haem analogues are indeed taken up and can be incorporated into ... that the metal ion of the porphyrin is removed during transport of the porphy- rin from the medium to the catalase protein in the cytoplasm. Alternatively, but less likely,...

The DIG-labelled oyvl-dsRNA has been observed in a large part of the gonad around the injection point, showing the efficiency of the administration of the dsRNA into the ... oyster tissues. The DIG-labelled dsRNA developed in the present study represents an important technical advance for examining the first crucial step in succe...

These changes in the RAR–DNA binding ... found. In lung, an increase in the expression of c-Jun produced a significant increase in cyclin D1 expression. These results may explain, at least in part, the conflic...

Moreover, in brain, the natural inhibitor of calpain, calpastatin, was preferentially converted into still active 15 kDa fragments (Table 1), whereas, in aorta, the inhibitor was predominantly inactivated. ... promoting NO production also induce calpain activation. Thus, the formation of NOS–HSP90 complexes may provide a new insight into the understanding of...
