Clastogenic and cytotoxic effects of spermine oxidation products in mouse lymphoma L5178Y cells.

abstract：:Cap-mediated translation is the default mechanism for the synthesis of proteins in eukaryotic cells. Increasingly, malignant cells have been found to have deregulation of this process. Return of normal translational control is associated with loss of tumorigenic potential in pre-clinical models. Currently, a variety o...

abstract：:For biochemical modulation, components of green tea have been shown to be useful modulators in combination with doxorubicin (DOX). We have confirmed that theanine enhances the antitumor activity of DOX due to inhibition of DOX efflux from tumor cells. Because theanine is a glutamate analogue, we found that it is assoc...
