Dr. Ananda Prasad: Comment #13

Comment #13

We studied the mechanism of zinc action on deoxythymidine kinase (TK) enzyme in a cell culture model HUT-78 cells.  These HUT-78 cells are human lymphoblast cell culture line and are very suitable for studies of Th cell functions.  We developed techniques to culture HUT-78 cells in both zinc deficient and zinc sufficient conditions. We showed that for the first time that zinc was required for the gene expression of deoxythymidine kinase.
