Deguelin at all concentrations fai

4、ls to reduce cell numbers in the presence of 1ng EGF but in the presence of EGF 20 ng reinstated deguelin mediated growth inhibition. Deguelin treatedcells show reduced expression of Survivin as determined by western blot and immunofluorescenceexaminations. Deguelin inhibits p-ERK and its downstream

5、 target p-STAT-3 and c-Myc expression in a dosedependent manner 1. Deguelin down-regulates Akt signaling probably by disrupting its association with Hsp90 in cultured HNSCC cells. Deguelin deguelin disrupts the association between Hsp 90 with survivin andCdk4. Deguelin deguelin treatment increases c

Deguelin inhibits the proliferation of MPC-11 cells in aconcentration- and time-dependent manner and causes the apoptotic death of MPC-11 cells. Followingexposure to deguelin, the phosphorylation of A

7、kt is decreased. Deguelin-induced apoptosis is characterizedby the upregulation of Bax, downregulation of Bcl-2 and activation of caspase-3 3.體內(nèi)研究 Deguelin (2 or 4 mg/kg, i.p.) reduces the in vivo tumor growth of MDA-MB-231 cells transplantedsubcutaneously in athymic mice 1. Deguelin (4 mg/kg, p.o.)

8、 treatment shows a great inhibition in tumorgrowth, which is demonstrated by reduced tumor size and improved mice survival and, indicating a significantanti-tumor ability by deguelin in vivo 2. In the colon cancer xenograft model, the volume of the tumor treatedwith deguelin is significantly lower t

This assay provides luminogenic substrate ina buffer system optimized for each specific caspase activity. The caspase cleavag

10、e of the substrate isfollowed by generation of a luminescent signal. The signal generated is proportional to the amount ofcaspase activity present in the sample. Protein (10 g) from the cell samples is diluted in water to a finalvolume of 50 L and added to a white 96-well microtitre plate, followed

11、by 50 L of Caspase-Glo-3 reagent.The plate is sealed and gently mixed at 300-500 rpm for 30 s and incubated at room temperature for 30 min.Luminescence is measured in a microplate reader (TECAN Infinite 200).MCE has not independently confirmed the accuracy of these methods. They are for reference on

12、ly.Cell Assay 1 Breast cancer cells are incubated with increasing concentration of Deguelin ranging from 31 nM to 500 nMfor 24, 48 and 72 h.

MDA-MB-231 cells (3.0 million cells/animal) are suspended in sterile PBSand then injected subcutaneously into the dorsal flank region using 23 g hypodermic needle. Animals

15、areobserved daily for the growth of palpable tumor at the site of injection. Once the tumor (approximately 50mm3) appears, the mice are randomized in to three groups, animals receiving either 1) vehicle as a control 2)Deguelin treatment at 2 mg/kg bodyweight dose or 3) Deguelin at 4 mg/kg body weigh

Animals aremonitored daily for the signs of drug/vehicle associated toxicity and weighed once weekly. Growth of tumor atthe site of cell injection is monitored every alternate day and o
