Exploring lincRNA's role in breast cancer

Once considered part of the "junk" of our genome, much of the DNA between protein-coding genes is now known to be transcribed. New findings by scientists at Fox Chase Cancer Center have identified several dozen transcripts ...

By determining structural effects of tumor-causing mutations, scientists obtain valuable information for drug discovery

(Medical Xpress)—For many patients with non-small-cell lung carcinoma (NSCLC), tumorigenesis is fueled by mutations that hyperactivate the epidermal growth factor receptor (EGFR) signaling protein. These ...

Cancer may require simpler genetic mutations than previously thought

Chromosomal deletions in DNA often involve just one of two gene copies inherited from either parent. But scientists haven't known how a deletion in one gene from one parent, called a "hemizygous" deletion, can contribute ...
