Effect of p53 on ubiquitin-activating enzymes (E1), ubiquitin-conjugating enzymes (E2) and ubiquitin-protein ligases (E3) obtained from comparison between empty vector and p53 vector transfected ovarian cancer cells.

<p>Fold changes were compared with Control after normalization of housekeeping genes such as actin and glyceraldehyde-3-phosphate dehydrogenase. H: high level (<30 cycles), L: low levels (30–35 cycles) and N/D (>35 cycles): not determined.
