Differential genome-wide profile of RBPJ, H3K4me1 and H3K4me3 as well as differential chromatin accessibility upon treatment with gamma-secretase inibithor (GSI) DAPT (ChIP-Seq).

Project description:The Notch signaling pathway regulates several processes including development and differentiation and its aberrant regulation leads to several diseases. Here, we investigated the differential chromatin accessibility, genome-wide distribution of the transcription factor RBPJ and the differential regulation of H3K4me1 and H3K4me3 upon pharmacological inhibition of the Notch pathway with gamma-secretase inibibitor (GSI) DAPT in mouse pre-T (Beko) cells.

Therapeutic effect of γ-secretase inhibition in KrasG12V-driven non-small cell lung carcinoma through derepression of DUSP1 phosphatase and inhibition of ERK

Project description:We have investigated the role of the Notch pathway in the generation and maintenance of KrasG12V-driven non-small cell lung carcinomas (NSCLCs). We demonstrate by genetic means that γ-secretase and Rbpj activities are both essential in the formation of NSCLCs. Interestingly, pharmacologic treatment of mice carrying endogenous NSCLCs with a γ-secretase inhibitor (GSI) blocks cancer growth and induces partial regression. Treated cancers show a reduction in Hes1 levels, reduced phosphorylated Erk, decreased proliferation and higher apoptosis. We demonstrate that HES1 directly binds and represses the promoter of DUSP1, a dual phosphatase with activity against phospho-ERK, and this repression is relieved by GSI treatment both in mouse and human NSCLCs. Our data provide proof for the in vivo therapeutic potential of γ-secretase inhibitors in primary NSCLCs and provide a mechanistic explanation for its therapeutical effect. We have included 6 samples. 3 with vehicle and 3 with the gamma-secretase inhibitor DAPT and we compare both groups.

Differential gene expression of a gamma secretase inhibitor treated human oral squamous cell carcinoma cell line

Project description:Notch signalling regulates various cancer cell beahviors. Influence of notch signaling inhibitor, a gamma secretase inhibitor (DAPT) on human oral squamous cell carcinoma is not yet widely investigated. Here, the differential mRNA expression of DAPT treated HSC4 cell line was examined using RNA sequencing technique. Results demonstraetd that DAPT regulated various pathways in HSC4, including cell cycle and DNA replication pathways.

Identification of naturally short gamma-secretase substrates

Project description:The intramembrane protease gamma-secretase has broad physiological functions, but also contributes to Notch-dependent tumors and Alzheimer’s disease. To identify naturally short substrates and non-substrates of gamma-secretase, we used four human cell lines of different tissue origins, breast cancer MCF7 cells, cervix carcinoma HeLa cells, T cell leukemia Jurkat cells and lymphoma U937 macrophage-like cells. The cell lines were treated overnight with the established gamma-secretase inhibitor DAPT or DMSO as a control. The proteomes of membrane fractions were determined by nano-liquid chromatography-tandem mass spectrometry and label-free quantitative proteomics. TNFRSF12A, PTPRCAP and C16orf54 were identified as potential naturally short gamma-secretase substrates, whereas other proteins with a short ectodomain including ‘pituitary tumor-transforming gene 1-interacting protein’ (PTTG1IP) did not show an increased abundance upon DAPT treatment.

Gene expression analysis of T-ALL cell lines treated with gamma-secretase inhibitor

Project description:Gain-of-function mutations in NOTCH1 are common in T-cell lymphoblastic leukemias making this receptor a promising target for drugs such as gamma-secretase inhibitors (GSI), which block a proteolytic cleavage required for NOTCH1 activation. However, the enthusiasm for these therapies has been tempered by tumor resistance and the paucity of information on the oncogenic programs regulated by oncogenic NOTCH1. Analysis of gene expression in GSI-responsive and GSI-resistant cell lines treated with Compound E identifies differential resopnses to GSI. Keywords: Drug response
