GANT61 (0, 5, 10, 20 M)inhibits clonogenic survival of human colon carcinom

4、a cell lines. GANT61 (20 M, 0-72 hr) down-regulatesGli1 and Gli2 expression in HT29 cells. GANT61 (0, 10 M or 20 M) differentially regulates genes involvedin the balance between cell death and cell survival 1. GANT-61 inhibits cell viability and induces apoptosisin pancreatic CSCs. GANT-61 inhibits

5、expression of downstream targets of Shh pathway, decreases Gli-DNAinteraction, Gli transcriptional activity and Gli nuclear translocation in pancreatic CSCs. GANT-61differentially regulates genes involved in cell survival, cell death and pluripotency. GANT-61 inhibits motility,invasion and migration

6、 of CSCs 2. GANT61 sensitivity positively correlates to GLI1 and negatively to MYCNexpression in the neuroblastoma cell lines tested. GANT61 downregulates GLI1, c-MYC, MYCN and CyclinD1 expression and induces apoptosis of neuroblastoma cells 3.體內(nèi)研究 GANT-61 (40 mg/kg, i.p., three days per week) inhib

7、its CSC tumor growth in NOD/SCID IL2R null mice 2.GANT61 (50 mg/kg, p.o.) enhances the effects of chemotherapeutic drugs used in the treatment ofneuroblastoma in an additive or synergistic manner and reduces the growth of established neuroblastomaxenografts in nude mice 3.PROTOCOLCell Assay 2 Cells

8、(1.5104) are incubated with 0, 1, 5 and 10 M of GANT-61 in 250 L of culture medium in 96-wellplate for 48 and 72 h. Cell viability is determined by the XTT assay. In brief, a freshly prepared XTT-PMSlabeling mixture (50 L) is added to the cell culture. The absorbance is measured at 450 nm with corre

9、ctionat 650 nm. The cell viability is expressed as OD (OD450 OD650). The apoptosis is determined by FACSanalysis of propidium iodide (PI)-stained cells. In brief, cells are trypsinized, washed with PBS andresuspended in 200 L PBS with 10 L RNAase (10 mg/mL) and incubated at 37C for 30 min. Afterincu
