abstract：:We have investigated the activity of STAT family members throughout a mammary developmental cycle. Transcripts for Stat 5 were upregulated during pregnancy whilst STAT1 and STAT3 mRNAs were expressed at constant levels. DNA binding complexes containing both STAT5a and 5b showed differing affinities for two naturally o...

The transporter is stereospecific and can be inhibited by both cytochalasin B and phloretin, with ki values of 4 microM and 30 microM for cytochalasin B and phloretin, respectively. Moreover, phlordzin does not affect uptake...

abstract：:Activation of p53 plays a central role in the cell's response to various stress signals. We investigated whether p53 is activated upon disruption of actin microfilaments, caused by cytochalasin D (CD). We show that treatment with CD leads to accumulation of p53 in the cells and activation of p53-dependent transcriptio...
