Table III.

Comparative efficacy for aromatase inhibition by TNM and LET in MCF-7AROM cells.

Treatment Concentration Aromatase activity (E1 fmole/mg protein/h) Inhibition (% control)
Control - 6.9±0.4a -
TNM (40 µg) 8 ng NFD 2.5±0.1b 63.8
LET (1 µM) 285 ng 2.6±0.1b 62.3

Results were expressed as mean ± SD, n=3 per treatment group.

a,bP=0.04. Data were analyzed by the two-sample Student's t-test. E1, estrone; TNM, Taheebo NFD Marugoto; LET, Letrozole; NFD, naphthofurandione; SD, standard deviation.
