(University of Texas M. D. Anderson Cancer Center) A study of racial disparities in health-related quality of life of colorectal cancer patients revealed among several findings, that Hispanics and blacks had a higher burden of poor health-related quality-of-life (HR-QoL) than white patients and that poor HR-QoL resulted in shorter median survival. Yet Hispanics had an average survival time of 85.4 months as compared to blacks at 47.8 months and whites at 43.2 months.

Tracking real-time proton induced radiation chemistry in water

Mon, 27 Mar 2017 00:00:00 EDT

(American Institute of Physics) Proton therapy is a promising form of radiation treatment used to kill cancerous cells and effectively halt their rapid reproduction, and the fundamental understanding for it is contained in the radiation induced water chemistry that occurs immediately after the interaction. The ensuing processes are therefore a subject of considerable scientific interest. Researchers describe their work exploring this ionization with an experimental setup, with enhanced temporal resolution, in this week's Applied Physics Letters.

Mon, 27 Mar 2017 00:00:00 EDT

(Johns Hopkins Medicine) In a research effort that merged genetics, physics and information theory, a team at the Schools of Medicine and Engineering at Johns Hopkins University has added significantly to evidence that large regions of the human genome have built-in variability in reversible epigenetic modifications made to their DNA.

Study provides path for new immunotherapy approaches to prostate cancer

Mon, 27 Mar 2017 00:00:00 EDT

(University of Texas M. D. Anderson Cancer Center) Prostate cancer, notoriously resistant to immunotherapy due to its immunologically cool nature, triggers two pathways to chill an immune attack after one immunotherapy drug fires up the immune system, researchers at The University of Texas MD Anderson Cancer Center report in Nature Medicine.

New tool allows analysis of single-cell RNA data in pre-malignant tumours

Mon, 27 Mar 2017 00:00:00 EDT

(Wellcome Trust Sanger Institute) Wellcome Trust Sanger Institute scientists and their collaborators have developed a new analysis tool that showed, for the first time, which genes were expressed by individual cells in different genetic versions of a benign blood cancer. Reported in Nature Methods today, the new computer tool -- Single Cell Consensus Clustering -- was shown to be more accurate and robust than existing methods of analyzing single-cell RNA sequence data, and is freely available for researchers to use.

New research shows how metabolism and epigenetics play a role in cancer development

Fri, 24 Mar 2017 00:00:00 EDT

(Oxford University Press USA) A study published in Briefings in Functional Genomics investigated how epigenetics can modulate human's genetic program -- it can emphasize or silence genes. The new research shows that if epigenetics is disrupted, it might switch on oncogenes (genes that in certain circumstances transform cells into tumor cells) or shut down tumor suppressors. Both events will transform cells into tumor cells and cause cancer.
