... [23] and the Bcl2 families [24]. On the molecular level, we show that the unique PRD on Mxi1-SRa contributes to the differential func- tions of Mxi1-SRa and Mxi1-SRb in Myc antagonism. Deletion of ... Mxi1-SRb, and to assess the transcriptional effects of these isoforms on these targets. A better molecular grasp on these Mxi1 iso- forms is necessary for underst...

Inhibitory effects of VVA1 on the hemolytic and cytotoxic activity of VVA2 The effects of VVA1 on the hemolytic activity of VVA2 were studied by incubation of human ... phenomenon requires further investigation [1]. On the basis of the present findings, we propose that one molecule of VVA1 interacts with two molecules of...
