Protocol

Cell experiment:

For cell proliferation experiments, DLD-1 and HCT116 cells are treated with 10 μM ML264 or with vehicle (DMSO). Live cells are collected at 24, 48 and 72 hours post treatment and their numbers are determined by counting using a Coulter counter. Each experiment is done in triplicate. In MTS assay, DLD-1 and HCT116 cells are treated with 10 μM ML264 or with vehicle (DMSO). After 24, 48, and 72 hours of incubations, 20 μL of MTS solution is added to each well and an analysis is performed. The measurement of the control (cells with medium and DMSO) is defined as 100% and the results from other measurements are calculated accordingly. Each experiment is done in sextuplicate. A cell cycle progression assay is performed. Each experiment is done in triplicate. The apoptosis rate is determined using the Alexa Fluor 488 Annexin V/Dead Cell Apoptosis Kit with analysis by flow cytometry. Each experiment is done in triplicate[2].

Animal experiment:

Mice[2]Nude mice are housed under specific pathogen-free conditions in ventilated and filtered cages under positive pressure. Xenograft tumors are generated by injecting subcutaneously 5×106 DLD-1 human colorectal cells into the right flank of 6-7 week old male nude mice. Tumor volume is determined by caliper measurement and calculated by established methods. When tumors reach a volume of about 100 mm6, mice are treated intraperitoneally (i.p.) with varying doses of ML264: 10 mg/kg daily, 10 mg/kg twice per day and 25 mg/kg twice per day, with each treatment regimen lasting for a duration of 10 days. The vehicle solution is used as the control treatment. Mice are monitored and weighed every two days. Experiments are terminated when the tumor’s greatest measurement reaches 2 cm. Tumors are excised and retained for further analyses[2].

ML264, a potent and selective inhibitor of kruppel-like factor 5 (KLF5), inhibits the growth of colorectal cancer. ML264 is chemically stable, unreactive with glutathione, has suitable aqueous solubility, is highly stable to mouse, rat, and human hepatic microsomes, making it a good candidate for in vivo anticancer studies [1].

ML264 inhibits the MAPK pathway by reducing EGR1 and KLF5 levels. KLF5 is a zinc finger-containing transcription factor which is highly expressed in rapidly dividing intestinal epithelial cells. KLF5 binds to GC-rich sequences in promoters of numerous genes, such as cyclin D1, cyclin B1/Cdc2, and integrin-linked kinase. KLF5 mediates the transforming effects of oncogenic H-Ras and plays an important role in regulating colon cancer pathogenesis [1].

In vitro: In a cell-based assay for proliferation of DLD-1 cells, the IC50 of ML264 was 29 nM. In a cell-based luciferase assay, the IC50 of ML264 was 81 nM. ML264 showed no cytotoxicity in the IEC-6 control cell line with an IC50 of >50 μM. The IC50 of ML264 was 560 nM, 130 nM and 130 nM in HCT116, HT29 and SW620, respectively. ML264 significantly reduced KLF5 expression. ML264 didn’t inhibit kinases associated with the KLF5 pathway. ML264 induced death of most colon cancer cell lines, with cytotoxicity toward several other tumor cell lines as well [1].

In vivo: In an established xenograft mouse model of colon cancer, ML264 efficiently inhibited growth of the tumor within five days treatment. This effect was caused by a significant reduction in proliferation and that ML264 potently inhibited the expression of KLF5 and EGR1, a transcriptional activator of KLF5 and EGR1, a transcriptional activator of KLF5 [2].
