Gemcitabine Gemzar of A66 and BEZ S 235 in SK OV 3 tumor xenograft model A66

Two non-lipid kinases that A66 P110 targets, IU III PI4K and PI3K-C2 . Our studies also add further weight to apply to the case for TGX 221 and IC87114 be very selective inhibitors Gemcitabine Gemzar of p110 and p110 . if at appropriate concentrations used in Figure 7 In vivo anti-tumor activity and Ver Change of the K Rpergewichts after treatment with the shape of A66 and BEZ S 235 in SK OV 3 tumor xenograft model A66 was administered QD 21 to 100 mg kg body weight up or BID to this day, 16-75 mg kg body weight, and REF QD 235 was 21-15 mg kg given body weight. Relative mean tumor volume after treatment with A66 235 and REF.

Using an ANOVA analysis was the importance of tumor shrinkage compared with the control group at 8.
12 days, 16 and 20 is calculated and differed significantly under the following conditions; IDB A66 8 days, A66 BID for 12 days, 12 days of IDB A66, A66 BID 16 days, day 20 IDB A66, A66, A66 and day 16 QD QD for 20 days. Bod yweight Change since the start of treatment in mice M, The BEZ treated with 235 and A66. Values are means S. Mr. E. seven or eight mice M Per group. The finding that A66 S potent flowering bridges phosphorylation of Akt PKB in a subset of cell lines showed that certain types of cells in high-Ma E on the activity Of p110 t. This is consistent with genetic studies showing that depletion of p110 blocked Signaling Akt PKB in cell lines with mutations in PI3K. It also supports earlier studies with PIK 75 and A66 and schl gt At least some types of cells sensitive to inhibitors of P110 are.
The finding that TGX insufficient 221 and IC87114 to inhibit the phosphorylation of Akt PKB on Ser473 or Thr308 to one of the cell lines tested, except for a partial effect of TGX 221 in MCF7 cells, indicating that this way is not on the catalytic activity of p110 and p110 from t in most cells. The results on p110 are not unexpected, but the results with TGX 221 are somewhat at odds with some previous studies. Although not found in oncogenicmutations p110, p110 overexpression can induce the transformation of . PIK3CB knockdown was shown that the F block Form of conductivity cell lines lack PTEN foci in transformation in vitro and in vivo tumor models. Knockdown of PIK3CB has been reported following is a slight reduction of Akt PKB phosphorylation in PTEN-deficient cells.
Although some functions of the p110 seems independent Ngig of the lipid kinase activity of t, the finding that TGX 221 to BL skirts to Akt PKB in PTEN-deficient cells as evidence of record that the catalytic activity t is required of p110 In this connection. However, it should be noted that these studies, a concentration of 20 to 100 times h Higher than the 221 from TGX used in this study may play an important M Opportunity for cross-reactivity are t with other isoforms of PI3K. To support this, Wee et al. found that 2 M TGX was necessary 221 for sen reduction of Akt PKB activation of PTEN deficient cells auszul, but at these concentrations, in part, the activation of Akt PKB in the DLD1 cell line decreased contains lt PIK3CA mutation. This would be consistent with our findings from this study show that the am Ren combinations of A66 S, TGX 221
