3、ciferase assay). ML264 lacks cytotoxicity in the IEC-6 control cell line (IC5050 M, 50=560 nM;HT29, IC50=130 nM; SW620, IC50=430 nM). Western blot analysis shows that ML264 significantly reducesKLF5 expression 1. The effects of ML264 are tested on the rate of cell proliferation of colon cancer cells

4、lines DLD-1 and HCT116 over 72 hours. ML264 efficiently inhibits the rate of proliferation of both cell lines. Asignificant decrease in proliferation is evident within 24 hours of treatment and by 72 hours the live cellnumbers of ML264-treated and vehicle-treated cells differed by 15- to 30- fold. A

5、n MTS assay that allows thequantification of metabolically active cells is performed. ML264 treatment significantly reduces the number ofcells undergoing mitosis in DLD-1 cells at 24, 48 and 72 hours 2.體內(nèi)研究 Single daily injections of ML264 at 10 mg/kg do not significantly affect tumor growth.

6、r, twice dailyinjections of ML264 at 10 mg/kg or 25 mg/kg result in significant reductions in tumor growth, and this effectcan be detected as early as two days after the first injection. The data also show that there is aconcentration-dependent effect of ML264 on the tumor volume. Statistical analys

In MTS assay, DLD-1 and HCT116cells are treated with 10 M ML264 or with vehicle (DMSO). After 24, 48, and 72 hours of incubations, 20 Lof MTS

11、e 2Administration 2 Nude mice are housed under specific pathogen-free conditions in ventilated and filtered cages under positivepressure. Xenograft tumors are generated by injecting subcutaneously 5106 DLD-1 human colorectal cellsinto the right flank of 6-7 week old male nude mice. Tumor volume is d

When tumors reach a volume of about 100 mm6, mice are treatedintraperitoneally (i.p.) with varying doses of ML264: 10 mg/kg daily, 10 mg/kg twice per day and 25 mg/kgtwice per day, with each treatment regimen lasting for a durati
