4、te cancer and colon cancer cell growth. Urolithin A increases mRNA andprotein expression of Phospho-p38 MAPK, and decreases mRNA and protein expression of MEKK1 andPhospho-c-Jun in T24 cells. Caspase-3 is also activated and PPAR- protein expression increased in drug-induced apoptosis 1. Urolithin A

5、exerts a dose- and time-dependent significant arrest at G2/M and S phasesafter treatments with 50 and 100 M at 24 and 48 h compared to control cells. It induces cell apoptosis with50 and 100 M 2. Urolithin A shows potent antiproliferative activity on HepG2 cells. When cell death isinduced by Urolith

6、in A, the expression of -catenin, c-Myc and Cyclin D1 are decreased and TCF/LEFtranscriptional activation is notably down-regulated. Urolithin A also increases protein expression of p53, p38-MAPK and caspase-3, but suppresses expression of NF-B p65 and other inflammatory mediators 3.體內(nèi)研究 The volume

7、of paw edema is reduced at 1 h after oral administration of urolithin A. In addition, plasma intreated mice exhibited significant oxygen radical antioxidant capacity (ORAC) scores with high plasma levelsof the unconjugated form at 1 h after oral administration of urolithin A 4.PROTOCOLCell Assay 2 H

8、uman colon cancer cells HT-29 are treated for 24 and 48 h at 100 and 50 M of Urolithin A and Iso UrolithinA aglycones and their glucuronide conjugates. Cell viability and proliferation are measured using a TC10automated cell counter with the addition of Trypan blue for viability determination. IC50

They are for reference only.Animal Mice: Paw edema is induced in the right hind paw of ICR mice by the subcutaneous injection of 1% -Administration 4 carrageenan in pysiological saline (50 L). The

10、inflammation level is quantified by the volume of paw edema.Urolithin A dissolved in 0.5% carboxymethylcellulose suspension is orally administered to the mice at 1 or 6 hbefore carrageenan injection. The anti-inflammatory effects of urolithin A on carrageenan-induced edema inmice are analyzed 4.MCE
