In Vitro Carmoisine augments the in vitro synthesis of leukotriene B4 (LTB4) and F2-isoprostanes from blood neutrophils. Carmoisine increases the formation of F2-isoprostanes from blood neutrophils at all tested concentrations[2].
In Vivo Carmoisine (49.3-493 mg/kg; oral administration; for 42 days; male Wistar rats) treatment increases MAPK8 expression at remarkably low and high concentrations, the expression of NFκB and GADD45α does not change[1]. Animal Model: Male Wistar rats (120-300 g)[1] Dosage: 49.3 mg/kg, 493 mg/kg Administration: Oral administration; for 42 days Result: Resulted in apoptosis according to MAPK8 expression.
