DAPT (GSI-IX)是一种新型γ-分泌酶抑制剂,抑制HEK 293细胞中全部Aβ产量, IC50为20 nM。DAPT功能性抑制γ-分泌酶而降低HEK 293细胞中全部Aβ产量,IC50为20 nM。DAPT作用于原代培养的人神经细胞,也抑制Aβ产量,作用于全部Aβ和Aβ42时, IC50分别为115 nM和200 nM,比作用于HEK 293细胞时低5-10倍。最新研究显示DAPT 抑制SK-MES-1 细胞增殖,这种作用存在浓度依赖性,IC50为11.265 μM。

细胞系 SK-MES-1
方法 Cells are seeded into 96-well plates and exposed to 0.1% DMSO or DAPT at concentrations in the range of 2.5 μM–160 μM for 72 hours. Cytotoxicity is determined with 3-(4, 5)-dimethylthiahiazo-(-z-y1)-3, 5-di-phenytetrazoliumromide (MTT) dye reduction assay with minor modifications. Briefly, after incubation with DAPT, 20 μL MTT solution (5 mg/mL in PBS) is added to 180 μL medium in each well and plates are incubated for 4 hours at 37 °C, and subsequently 150 μL DMSO is added to each well, and mixed by shaking at room temperature for 15 minutes. Absorption is measured by an enzyme-linked immunosorbent assay at 490 nm to determine absorbance values.

实验结果 The levels of Jagged1 and Notch1 were decreased after adding the Notch inhibitor, DAPT, indicating that DAPT successfully inhibited the Jagged1/Notch signaling pathway. In addition, the expression of VEGF protein was reduced after adding DAPT (Fig. 5).

实验结果 DAPT treatment resulted in a large increase in vessel density and expansion of the vascular plexus in the postnatal retina of control mice (Fig. 2A, C, E, G). DAPT completely rescued the defect in SENP1-ecKO pups (Fig. 2B, D, F, H), which resulted in vascular length, vascular coverage, and tip sprouts growth comparable to the control group (Fig. 2I-K).

实验结果 "Both terminal deoxynucleotidyl transferase–mediated deoxyuridine triphosphate nick end labeling (TUNEL) staining and measurements of the activated or cleaved caspase 3 showed reductions of apoptotic cells in Dll4-Notch inhibitor–treated JE-3 and BeWo tumors. In contrast, treatment of PlGF-negative MDAMB-231 tumors with DAPT and Dll4 blockade showed completely opposite effects on cell proliferation and apoptosis, tipping the balance toward an apoptotic phenotype."
