(F) Tumour tissues were further analysed to detect the efficacy of the inhibitors by IHC staining using p-EGFR and Notch1. (4Fa) Notch1 staining was mostly confined on the cell membrane. (4Fc) After Erlotinib treatment, the Notch1 protein was cleaved and translocated to the nucleus. (4Fb) p-EGFR was overexpressed in the control group. (4Fd) Erlotinib treatment inhibited p-EGFR expression. (4Fe-f) PF-03084014 treatment reduced both Notch1 and p-EGFR expression. (4Fg-h) Synthetic therapy reduced the activation of Notch1 and EGFR pathway. Scale bar = 50 μm. *P < .05, **P < .01, ***P < .001

PF-03084014 inhibits Notch receptor cleavage in cellular assays using HPB-ALL cells that harbor mutations in both the heterodimerization and PEST domains in Notch1with IC50 of 13.3 nM. PF-03084014 downregulates Notch target genes Hes-1, and cMyc expression in HPB-ALL cells with IC50 of <1 nM and 10 nM, respectively. PF-03084014 inhibits cell growth of a subset of human T-ALL cell lines (HPB-ALL, DND-41, TALL-1,and Sup-T1) through induction of cell cycle arrest and apoptosis with IC50s of 30-100 nM. [1] PF-03084014 reduces proliferation of HUVECs with IC50 of 0.5 μM, and decreases the lumen formation with an IC50 value of 50 nM. PF-03084014 (1 μM) has no antiproliferative effect in MX1 cells; however, it inhibits migration by 95%. [2] |

| 体内研究 | PF-03084014 orally administrated in a single dose of 200 mg/kg, causes maximal NICD inhibition for ∼80% in xenograft HPB-ALL tumors. PF-03084014 shows robust antitumor activity in this mode with a maximal tumor growth inhibition of ∼ 92% at dose of 150 mg/kg, accompanied by a significant reduction of NICD/Notch1, tumor mitotic index (Ki67), and apoptosis (activated caspase-3) staining. [1] PF-03084014 (120 mg/kg) induces apoptosis, antiproliferation, reduces tumor cell self-renewal ability, impaires tumor vasculature, and decreases metastasis activity in breast cancer HCC1599 tumor-bearing mice. PF-03084014 treatment displays significant antitumor activity in various types of the breast xenograft models with TGI value of at least 50%. [2] |

γ-secretase assay: A DNA fragment encoding amino acids 596 - 695 of the 695-aa isoform of APP (APP695) and the Flag sequence (DYKDDDDK) at the C terminus is generated by PCR amplification with suitably designed oligonucleotides and the APP695 cDNA. The Met that serves as the translation start site is residue 596 of APP695 (the P1 residue with respect to theβ-secretase cleavage site). This DNA fragment is inserted into the prokaryotic expression vector pET2-21b. The recombinant protein, C100Flag, is overproduced in Escherichia coli [strain BL21(DE3)] and purified by Mono-Q column chromatography. C100Flag (1.7 μM) is incubated with cell membranes (0.5 mg/mL) in the presence of CHAPSO, CHAPS (3-[(3-cholamidopropyl)dim-ethylammonio]-1-propanesulfonate), or Triton X-100 (0, 0.125, 0.25, 0.5, or 1%) in buffer B (50 mM Pipes, pH 7.0y 5mM MgCl2/5 mM CaCl2/150 mM KCl) at 37°C. The reactions are stopped by adding RIPA (150 mM NaCl/1.0% NP-40/0.5% sodium deoxycholatey 0.1% SDS/50 mM Tris HCl, pH 8.0) and boiling for 5 min. The samples ae centrifuged and the supernatant solutions are assayed for the Aβ peptides by ECL. The Aβ40- and Aβ42-related products from γ-secretase-mediated processing of C100Flag possess a Met at the N terminus and are thus defined as M-Aβ40 and M-Aβ42, respectively. Likewise, supernatant solution (0.125 mg/mL) from CHAPSO-extracted HeLa cell membranes (solubilized γ-secretase) is incubated with C100Flag (1.7 μM) in buffer B containing 0.25% CHAPSO and subsequently assayed for M-Aβ40 and M-Aβ42 by using ECL. |
