Fig. 3. Effects of tubercidin and SAM:SAH ratios on proteasome activity in cytosol and nuclear fractions.

Fig. 3

A. Huh7CYP cells were exposed for 24h to 10 μM tubercidin and then proteasome activity was measured in the prepared cytosolic and nuclear fractions. * is p<0.05 in proteasome activity in nuclear extracts, controls vs tubercidin; # is p<0.05 in proteasome activity in cytosols, control vs tubercidin. B. proteasome activity in liver cytosols exposed to low SAM:SAH ratio (2) for 4 hr. * is p<0.05 in proteasome activity between control and treatments.
