Nonsense mediated mRNA decay genomics:

Human genetic diseases differ in whether NMD typically aggravates or alleviates the phenotypic effects of nonsense variants // Failure to trigger NMD is a cause of ineffective gene inactivation by CRISPR–Cas9 gene editing // NMD strongly determines the efficacy of cancer immunotherapy, with only transcripts that escape NMD predicting a response

Matched exome and transcriptome data can systematically elucidate the rules of NMD targeting in human tumors, explaining ¾ of the variance in NMD efficiency. Applying our NMD model identifies signatures of positive and negative selection on nonsense mutations in human tumors, and provides a classification for tumor-suppressor genes.

Matching transcriptomes between cancer cell lines and tumors:

A joint analysis of genomes, transcriptomes and epigenomes matches human cancer cell lines to tumor (sub)types in TCGA // ~20% of the 614 examined cell lines were not a good match to the cancer type they were meant to represent // ~7% of cell lines are a close match a different cancer type, sometimes representing instances of metastatic skin cancer
