An international team documented TP53 mutation-related genomic changes across dozens of cancer types using data generated with five platforms for the Cancer Genome Atlas project.
The subtypes — which were distinguished from one another using proteomic data — were associated with proliferation, immune response, metabolism, and invasion.
Researchers found that hypoxia was associated with elevated genomic instability in 10 tumor types and saw widespread hypoxia-associated dysregulation of miRNAs.
Gene expression data revealed two groups of human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinomas corresponding to distinct survival outcomes.
The study looked at chromatin accessibility in 410 TCGA tumors in the context of broader genomic features to explore functional effects of regulatory features.
Using TCGA and ICGC data, researchers have identified 180 amino acid residues within 160 human proteins that appear to be hotspots for cancer-linked mutations.
The third set of papers out this week from The Cancer Genome Atlas touches on ways to cluster tumors, oncogenic processes that contribute to oncogenesis, and more.
A genetic analysis of salmon scales collected over the course of a century points to a sharp decline in the number of fish returning each year to river in British Columbia, CBC reports.
