Understanding its molecular pathogenesis is crucial for improving diagnosis and treatment. Integrated analysis of genomic, proteomic, post-translational modification and metabolomics data on 99-treatment naive GBMs provided insights to GBM biology. Multiple key findings emerged that were not known from traditional genomic analyses: (1) Analysis of protein phosphorylation identified key signaling intermediates in the RTK/RAS path-way common to multiple RTK genomic alterations (PTPN11 and PLCG1), potentially offering common therapeutic targets for different oncogenic drivers in GBM. (2) Phosphoproteomics also identified potential druggable targets based on kinase-substrate pathway analysis, as well as novel phosphoprotein targets associated with the regulation of telomere length by ATRX in IDH mutants. (3) TP53 protein abundance in GBM is regulated by protein/phosphoprotein effectors (4) Four immune GBM subtypes exist, characterized by distinct immune cell population differences – Immune High and Immune Low phenotypes in GBM were driven by tumor-associated macrophage markers, and associated with distinct epigenetic modifications and histone acetylation patterns. (5) The mesenchymal subtype displays EMT signatures specific in tumor cells, distinct from infiltrating immune cells. (6) Histone H2B acetylation and immune-low GBM was driven largely by BRDs, CREBBP, and EP300. (7) Identification of key metabolic changes in IDH mutants facilitating the accumulation of onco-metabolite 2-HG were also associated with lipidomic changes. This work identifies additional therapeutic channels for GBM and novel information useful for more accurate stratification patients for effective treatment. Citation Format: Jill S. Barnholtz-Sloan.

Shogaol, paradol, and gingerol are obtained from many plants belonging to the family Zingiberaceae such as dried ginger and grain of paradise and shows different pharmacological activities. The current study evaluated the anticancer potential of these compounds in combination with chemotherapeutic platinum drugs against breast cancer cells. Cytotoxicity assay, apoptosis assay, immunofluorescent staining cell surface marker analysis, and wound healing assay were used for evaluating the cytotoxic potential of these compounds alone and in combination with platinum chemotherapeutics agents against naive and resistant breast cancer cell lines (MDA-MB-231 and MCF-7adr, respectively). Platinum drugs showed synergism in combination with shogaol and gingerol against the resistant breast cancer cells (MCF-7adr) with a Combination Index (CI) values of 0.39 and 0.54, respectively. A significant increase was observed in the percentages of early and late apoptotic cells for MDA-MB-231 cells treated with 6-shogaol for 24h. Significant decrease in CD44+/CD24- subpopulation was recorded in both cell lines using flowcytometric analysis. In the Wound healing assay, cells treated with the test compounds migrated significantly slower than control and needed a longer time to heal the scratch. In conclusion, gingerol, shogaol, and paradol compounds showed synergistic cytotoxicity with platinum-based drug and augmented their migration inhibitory activity, apoptotic effects, and tumor-associated stem cell suppressive the potential within naive and resistant breast cancer cells.
