Quantitation of apoptosis and viability in Jurkat and JPX-9 cells treated with ZnCl
. A) JPX-9 cell treated with Zn show higher levels of apoptosis, while JPX-9 cell treated with Cd and Jurkat cell treated with either Zn or Cd showed lower levels. Y-axis is % apoptosis, and X-axis is hours after treatment. B) and C) Cell viability was quantified using a modified MTT colorimetric assay. Quantification of viability in HTLV-I transformed cell lines, as indicated, was after treatment with ZnCl2 or CdCl2 for 24 hours (B) or 48 hours (C). HTLV-I transformed cell lines treated with Zn showed lower cell viability compared to cells treated with Cd. Y-axes are % viability with 100% set as 1; X-axes indicate the name of the cell line.
