SIRT1 promotes formation of breast cancer through modulating Akt activity:

This is a bit disturbing - and the opposite of what I expected.

CM et al [26] showed that Resveratrol (RES), as a
Sirtuins activator, promotes cytotoxicity and pr
o- differentiation activity on breast cancer cells, which
was in some conflict with our research. Indeed, RES
activates SIRT3 in addition to SIRT1, and SIRT3 acts as
a tumor suppressor inducing cancer cell death
through the regulation of key proteins for malignant
transformation [27].
Also, they showed the effects of
RES on breast cancer cells were modulated not only
by SIRT1/SIRT3, but also by mitochondrial complex
inhibition. Most importantly, they found cytotoxic
effects of RES, which is dependent on the increase of
SIRT1 level, was only in high glucose containing
medium, but not normal medium. We also detected
the expression of SIRT1 in RES-treated breast cancer cells in our cultured conditions, however,
there was no significant change in SIRT1 level (Figure S3). Thus
SIRT1 can function either as a tumor suppressor or as
an oncogene, depending on the cellular background
or environment cells are growing in.
A little reassuring?

I think this was covered in the early days of the resveratrol forum. Maybe not the same studies, but the outcome vis-a-vis breast cancer cells.
