生物活性

Citric acid monohydrate is a natural preservative and food tartness enhancer. Citric acid monohydrate induces apoptosis and cell cycle arrest at G2/M phase and S phase. Citric acid monohydrate cause oxidative damage of the liver by means of the decrease of antioxidative enzyme activities. Citric acid monohydrate causes renal toxicity in mice[1][2][3].

体外研究
(In Vitro)

Citric acid monohydrate (0-12.5 mM; 24 h) shows antiproliferative activity in a dose dependent manner[3].
Citric acid monohydrate (12.5 mM; 72 h) induces apoptosis and cell cycle arrest at G2/M phase and S phase in a dosedependent manner[3].
Citric acid monohydrate (12.5 mM; 48 h) increases the expression of FAS, BAX, BID, AIF, EndoG, cytochrome c, PARP, GADD153, GRP78 and caspase-3, -8, -9, and decreases of BCL-2 and BCL-Xl[3].

Shanghai Jinpan Biotech Co Ltd has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究
(In Vivo)

Citric acid monohydrate (120, 240, and 480 mg/kg; i.p.) significantly decreases GSH-Px activity and induces an increase in the MDA (malonyldialdehyde) levels in mouse liver[1].
Citric acid monohydrate (120, 240, and 480 mg/kg; i.p.) induces apoptosis by increases caspase-3 activity in a dose-dependent manner in mouse hepatocytes[1].
