چکیده
Abstract High-risk medulloblastomas are tumours with a poor survival prognosis (≤ 50%), which currently treated radiation therapy and DNA-damaging chemotherapy. The severe side effects of these treatments, including developmental problems secondary tumours, underscore the need for new treatments reduced toxicity. An attractive target such is Myc-family proteins since high-risk amplify either N-Myc (SHH-MB, G4-MB) or c-Myc (G3-MB). While from Myc family themselves often referred to as pharmacologically intractable, their levels activity can be modulated by indirect targeting, e.g. inhibition located upstream downstream c-Myc/N-Myc. diverse cellular processes pathways that involved in, however, suggest several must interrupted simultaneously achieve lasting effect. To identify multimodal interventions against Myc, we performed principal component analysis RNA sequencing data patient-derived medulloblastoma cells (MB002, G3, MYC-amplified) DAOY (SHH-group, no MYC amplification) were 120 small molecules. In subsequent analysis, focused on selection ~ 40 genes represent common regulators targets N-Myc. Applying particular markers, expect drugs affect different associated at opposite ends PC1 PC2 axis should have synergistic Additionally, expected closer each other, closely related pathways, would effect antagonistic. Our PCA distribution method used select combinations in manner easily extended compounds. This approach may allow fast screening compounds estimation treatment

15 صفحه اولA streamlined search technology for identification of synergistic drug combinations
A major key to improvement of cancer therapy is the combination of drugs. Mixing drugs that already exist on the market may offer an attractive alternative. Here we report on a new model-based streamlined feedback system control (s-FSC) method, based on a design of experiment approach, for rapidly finding optimal drug mixtures with minimal experimental effort. We tested combinations in an in vi...
متن کاملA Computational Approach for Identifying Synergistic Drug Combinations
A promising alternative to address the problem of acquired drug resistance is to rely on combination therapies. Identification of the right combinations is often accomplished through trial and error, a labor and resource intensive process whose scale quickly escalates as more drugs can be combined. To address this problem, we present a broad computational approach for predicting synergistic com...

Data visualization is the process of transforming data, information, and knowledge into visual form, making use of humans’ natural visual capabilities which reveals relationships in data sets that are not evident from the raw data, by using mathematical techniques to reduce the number of dimensions in the data set while preserving the relevant inherent properties. In this paper, we formulated d...
