In this study, we report on the apparent effect of increased tyrosine phosphorylation events on the assembly and integrity of adherens junctions (AJs) and on paracellular permeability in Caco-2 cells. Cell monolayers were incubated with the phosphotyrosine phosphatase inhibitor vanadate/H 2 O 2 ....
Exceptionally high DNA contents were found in supramedullary neuron (SN) nuclei of the pufferfish Diodon holacanthus by quantitative microfluorimetric assay. This phenomenon has been explained by endoreplication, the functional significance of which is still unclear. In this view, the peptidergic...
