BB polyphenols reduced aging-related increase of inducible hsp transcripts. Expression levels of small heat-shock proteins, relative to actin, were determined by RT-PCR in populations treated with 200 g/ml of blueberry polyphenol (BB PP) at 25 °C. Graph shows mean of two independent experiments with SEM; **P < 0.01 vs. day 0 within treatment; *P < 0.05 vs. day 0 within treatment.
