Pharmacogenomics for the efficacy of platinum-based chemotherapy: Old drugs, new integrated perspective.

Platinum-based chemotherapy remains the cornerstone of treatment for many malignancies. However, although therapeutic efficiency varies greatly among individuals, there is a lack of pharmacogenomic biomarkers that can be used in clinical settings to identify chemosensitive patients and allow stratification. With the development of high-throughput screening techniques and systems biology approaches, a growing body of evidence has shown that platinum resistance is a multifactorial, multi-dimensional, dynamic process incorporating genetic background, tumor evolution and gut microbes.

The molecular classification of astrocytic tumors.

Aim: This study will explore the genetic and epigenetic alterations in astrocytomas, and identify the critical molecular signatures and signaling pathways for prognosis assessment by multiplatform comprehensive analysis.

Method: We performed integration analyses of incorporating DNA methylation, mRNA expression, microRNA expression, and long non-coding RNA (lncRNA) expression in 33 astrocytic tumor tissues and 9 non-tumor brain tissues.

Result: We observed that 11,795 DNA methylation sites, 3,627 genes, 136 microRNAs, and 3,334 lncRNAs were significantly differential between tumors and non-tumor brain tissues, and the filtered signatures through comprehensive analysis were significantly enriched in calcium signaling pathway.

Silencing of Forkhead box D1 inhibits proliferation and migration in glioma cells.

Despite the extensive role of Forkhead box transcription factors in the development and progression of various cancers, little is known about their role in glioma. We examined the expression and function of Forkhead box D1 (FOXD1) in glioma cell behavior and found that FOXD1 was upregulated and directly correlated with the glioma grade. Data analysis also revealed significant differences in FOXD1 expression for both gene expression profiles (GSE4290 and GSE7696) and the TCGA datasets.

PPIC, EMP3 and CHI3L1 Are Novel Prognostic Markers for High Grade Glioma.
