Figure 3. — Telomerase activity expressed in % relative to telomerase activity of the positive control (HeLa cell extract) for the untreated cells or after treatment with 08AGTLF, Nutrient 4 and TA-65. Error bars represents the standard deviation of the mean. Each mean was estimated from triplicate experiments. Asterisks indicate significant differences in the mean absorbance values measured after treatment with each activator compared with untreated cells (**P<0.01, ***P<0.001 and ****P<0.0001) at the indicated concentrations.
