Skeletal muscle appears to play a central role in the development of insulin resistance (IR) and consequently the metabolic syndrome due to high-fat diets, obesity, and aging. Recent evidence suggests that some bioactive compounds present in natural products can affect blood glucose, possibly due to interactions between the compounds and glucose transporters. As an objective, to evaluate the effect of the extract of the green bean (PV, Phaseolus vulgaris) and apple of small fruit of thinning (Malus domestica, MAF and MIT extracts) on the incorporation of glucose in C2C12 muscle cells. For this, the cytotoxic effect of the extracts on the cells was determined by detecting formazan. Subsequently, glucose incorporation was determined using a fluorescent glucose analog in cells treated with the extracts. Finally, the effect of the extracts on IL-6 and TNFα production was evaluated by ELISA.

Results:

PV and MAF decreased 50% of viability at 1000µg / mL while MIT only decreased 10% at that concentration. PV had no significant effect on glucose incorporation and the MAF and MIT extract extracts significantly increased glucose incorporation at 100 µg / mL (13500 and 18000 URF respectively). PV increases the secretion of IL-6 and TNF-α, MAF and MIT only increase the expression of IL-6.

Conclusion:

These results make it possible to establish natural extracts derived from thinning small fruit apple can be used as a possible treatment for pathologies with high blood glucose levels.
