In vitro
In vitro

(-)-Epicatechin stimulates mitochondrial respiration and oxygen consumption in Panc-1 cells. Human normal fibroblasts are not affected. (-)-Epicatechin sensitizes Panc-1, U87, and MIA PaCa-2 cells with an average radiation enhancement factor (REF) of 1.7, 1.5, and 1.2, respectively. (-)-Epicatechin does not sensitize normal fibroblast cells to ionizing radiation with a REF of 0.9, suggesting cancer cell selectivity. (-)-Epicatechin enhances Chk2 phosphorylation and p21 induction when combined with radiation in cancer, but not normal cells[2].
Cell Research Cell lines Panc-1 cells
Concentrations 0-200 μM
Incubation Time 1 h
Method

Panc-1 cells are seeded into T-150 flasks and on the next day, cells are treated with different concentrations of (-)-epicatechin for 1 h, then harvested and solubilized in 10 mM HEPES (pH 7.4), 40 mM KCl, 1%Tween-20, 1 µM oligomycin, 1 mM PMSF,10 mM KF, 2 mM EGTA, and 1 mM Na3VO4. COX activity is measured in the presence of 20 mM ascorbate and 200 µM substrate cytochrome c from cow heart.

In vivo

Aging has deleterious effects on modulators of muscle growth/differentiation, the consumption of modest amounts of the flavanol (−)-epicatechin can partially reverse these changes. In mice, myostatin and senescence-associated β-galactosidase levels increase with aging, while those of follistatin and Myf5 decrease. (−)-Epicatechin decreases myostatin and β-galactosidase and increases levels of markers of muscle growth. In humans, myostatin and β-galactosidase increase with aging while follistatin, MyoD and myogenin decrease. Treatment for 7 days with (−)-epicatechin increases hand grip strength and the ratio of plasma follistatin/myostatin[1]. Low-dose (−)-epicatechin treatment resulted in significant increases in skeletal muscle capillarity, mitochondrial biogenesis, and oxidative enzyme activity, which corresponded to lower muscle fatigue and higher endurance capacity when compared to the placebo group. (−)-epicatechin may potentially regulate the protein expression between angiogenic and antiangiogenic factors, such as VEGF-A and TSP-1, respectively[3].

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
