Regular physical exercise provides many health benefits, protecting against the development of chronic diseases, and improving quality of life. Some of the mechanisms by which exercise provides these effects are the promotion of an anti-inflammatory state, reinforcement of the neuromuscular function, and activation of the hypothalamic-pituitary-adrenal (HPA) axis. Recently, it has been proposed that physical exercise is able to modify gut microbiota, and thus this could be another factor by which exercise promotes well-being, since gut microbiota appears to be closely related to health and disease. The purpose of this paper is to review the recent findings on gut microbiota modification by exercise, proposing several mechanisms by which physical exercise might cause changes in gut microbiota.

The effect of the naturally occurring polyphenol resveratrol (3,5,4'-trihydroxy-trans-stilbene; RES) on growth, cell cycle, and cyclins A, E, and B1 expression was investigated in the human SK-Mel-28 melanoma cell line. In addition, the structurally related compounds 4-hydroxy-trans-stilbene (4HST), piceatannol (3,5,3',4'-tetrahydroxy-trans-stilbene (PICE), and 4-trans-stilbenemethanol (4STMe) were also assayed in order to investigate the requirements of stilbenes to exert activity against melanoma cells. Both RES and 4HST inhibited cell growth in a dose- and time-dependent manner and upregulated the expression of cyclins A, E, and B1 with subsequent irreversible arrest of melanoma cells in the S-phase, concomitant with a decrease in G0/G1 and G2/M phases. In addition, potent apoptosis-mediated cell death was detected with the annexin V assay whereas no apoptosis was observed by flow cytometry, which encourages the assay of different methodologies to evaluate the effect of polyphenols on cell lines. The effect of PICE was not evaluated because of its instability in the reaction medium. No effect on cell cycle and cyclins expression was observed when 4STMe was assayed, which supported the critical requirement of the 4'-hydroxystyryl moiety to exert the above effects. In addition, this structural requirement also influenced the cellular uptake of stilbenes. The presence of two extra hydroxyl groups in RES increased its cytotoxicity whereas it diminished its efficiency to inhibit cell growth, upregulate cyclins expression, and arrest cell cycle in the S-phase with respect to 4HST. The present study suggests that the antimelanoma properties of dietary stilbenes, such as grape RES, cannot be ruled out, taking into account previous studies concerning the relationship between plasma and tissue concentrations and pharmacological activity of RES in animal models.

A number of pharmacokinetic studies have shown marked differences in the plasma metabolic profile of resveratrol (RES) between humans and animals and between individuals of the same species, which complicates the identification of the putative bioactive metabolites responsible for the beneficial effects of RES. On the basis of the physiological similarity between pigs and humans, the aim of this work was to characterize the metabolic profile and pharmacokinetics of RES in the plasma of pigs and to compare this to values reported in humans. RES (5.9 mg/kg of body weight) was orally administered to pigs. The following metabolites were identified in plasma using HPLC-MS/MS: RES-diglucuronide (1), two isomers of RES-sulfoglucuronide (2, 3), two isomers of RES-glucuronide (4, 5), RES-sulfate (6), and RES. The most abundant metabolites were 2, 5 (identified as resveratrol 3-O-glucuronide), and 6. The t(max) ranged from 0.9 h for compounds 2 and 5 to 2 h for compound 3. The highest C(max) value was 2223 ng/mL (5.5 μM) for metabolite 5, which was 2.6-, 3.3-, and 12-fold higher than that for metabolites 6, 2, and 3, respectively. Peak plasma levels of RES (53 ng/mL; 0.23 μM) were detected 0.5 h after RES ingestion. Apart from the low levels of RES aglycone, the RES metabolic profile in pigs differs from that found in humans. The identification of the actual active RES metabolites is a challenge that requires more complex studies which should take into account many possible influencing factors such as age, gender, and methodological approaches.
