COX-2
|
Hexahydrocurcumin (0-25 μM; 24-48 hours; HT-29 cells) treatment significantly decreased the viability of HT-29 colon cancer cells in a time- and concentration-dependent. The respective IC
50
values for 24 and 48 h of Hexahydrocurcumin exposureare 77.05 and 56.95, respectively.
Hexahydrocurcumin (0-25 μM; 24-48 hours; HT-29 cells) combined with 5-fluorouracil (5-FU; 5 µM) markedly reduces the COX-2 expression. The level of COX-1 is not altered.
Hexahydrocurcumin (0-25 μM; 24-48 hours; HT-29 cells) combined with 5-fluorouracil (5-FU; 5 µM) markedly reduces the COX-2 protein. The level of COX-1 protein is not altered.
Hexahydrocurcumin (7-14 μM; 24 hours) attenuates lipopolysaccharide (LPS)-elicited increase of prostaglandin E
2
(PGE

) in murine macrophages (RAW 264.7) in a concentration-dependent manner.
Cell Viability Assay
| Cell Line: | HT-29 cells |
| Concentration: | 0 µM, 5 µM, 10 µM, 25 µM |
| Incubation Time: | 24 hours or 48 hours |
| Result: | Significantly decreased the viability of HT-29 colon cancer cells. |
RT-PCR
| Cell Line: | HT-29 cells |
| Concentration: | 25 µM |
| Incubation Time: | 24 hours |
| Result: | Combined with 5-fluorouracil (5-FU; 5 µM) markedly reduced the COX-2 expression. |
Western Blot Analysis
| Cell Line: | HT-29 cells |
| Concentration: | 25 µM |
| Incubation Time: | 24 hours |
| Result: | Combined with 5-fluorouracil (5-FU; 5 µM) markedly reduced the COX-2 protein. |
Hexahydrocurcumin (50 mg/kg; oral administration; daily; for 16 weeks; male Wistar rats) treatment significantly reduces the numbers of aberrant crypt foci (ACF) in colon cancer rats. Hexahydrocurcumin also markedly decreases COX-2 protein expression. The levels of COX-1 protein is not different from normal rats.
| Animal Model: | Male Wistar rats (100-120 g) injected with dimethylhydrazine (DMH) |
| Dosage: | 50 mg/kg |
| Administration: | Oral administration; daily; for 16 weeks |
| Result: | Significantly reduced the numbers of ACF in colon cancer rats. Also markedly decreased COX-2 protein expression. |
