TL;DR: A large-scale RNAi screen is conducted in which viability effects of mRNA knockdown were assessed for 7,837 genes using an average of 20 shRNAs per gene in 398 cancer cell lines, outlining the classes of cancer dependency genes and their relationships to genetic, expression, and lineage features.
Journal ArticleDOI
Quassinoids: From traditional drugs to new cancer therapeutics
TL;DR: Quassinoids are a group of compounds extracted from plants of the Simaroubaceae family, which have been used for many years in folk medicine as mentioned in this paper and have a wide range of inhibitory effects.
Journal ArticleDOI
Disabling c-Myc in Childhood Medulloblastoma and Atypical Teratoid/Rhabdoid Tumor Cells by the Potent G-Quadruplex Interactive Agent S2T1-6OTD
Tarek Shalaby,André O. von Bueren,Marie-Louise Hürlimann,Giulio Fiaschetti,Deborah Castelletti,Tera Masayuki,Kazuo Nagasawa,Alexandre Arcaro,Ilian Jelesarov,Kazuo Shin-ya,Michael A. Grotzer +10 more
TL;DR: S2T1-6OTD proved to be a potent c-Myc inhibitor through its high-affinity physical interaction with the G-quadruplex structure in the c- myc promoter.
Journal ArticleDOI
NOTCH ligands JAG1 and JAG2 as critical pro-survival factors in childhood medulloblastoma
Giulio Fiaschetti,Christina Schroeder,Deborah Castelletti,Alexandre Arcaro,Frank Westermann,Martin Baumgartner,Tarek Shalaby,Michael A. Grotzer +7 more
TL;DR: It is demonstrated that MB cells bear abnormal levels of distinct NOTCH ligands, and a mechanistic link between the oncogene MYC and NOTCH pathway in MB is described for the first time, by identifying JAG2 as MYC target, and by showing thatMB cells acquire induced expression of J AG2 through MYC-induced transcriptional activation.
Journal ArticleDOI
Bone morphogenetic protein-7 is a MYC target with prosurvival functions in childhood medulloblastoma.
Giulio Fiaschetti,Deborah Castelletti,Stefan Zoller,Alexander Schramm,Christina Schroeder,Masaya Nagaishi,Duncan Stearns,Michel Mittelbronn,Angelika Eggert,Frank Westermann,Hiroko Ohgaki,Tarek Shalaby,Martin Pruschy,Alexandre Arcaro,Michael A. Grotzer +14 more
TL;DR: Findings indicate that high MYC levels drive BMP7 overexpression, promoting cell survival in MB cells, and suggests the potential relevance of targeting the BMP/SMAD pathway as a novel therapeutic approach for the treatment of childhood MB.
