... polyamine a nalogues are presently undergoing Phase I and Phase II clinical evaluations in the US. In L56Br-C1 cells, DENSPM treatment induced an increase in SSAT activity, which resulted in a ... DENSPM-induced increase in SSAT activity was not as extensive as in any of those t wo cell lines. The depletion of the polyamine pools was however, similar in all three cell lines. T...

Type I and type II cadherins are characterized ... extracellular cadherin repeats, EC1–EC5; intracellularly, they are linked to the actin cytoskeleton [4]. During embryonic development, cadherins control diverse morphogenetic proc...
