Tat stimulates apoptosis. A) Cell cycle distribution of TE671 cells at different times after transfection with HA-cyclin B1 or pCI-Tat, measured by flow cytometric analysis (FACS). Sub-G1 peak represents apoptosis. B) Apoptosis induced by overexpression of Tat or cyclin B1; plot based on data shown in A.
