Summary of A long-noncoding RNA regulates repair of DNA breaks in triple-negative breast cancer cells
### Summary This article highlights the discovery of a long non-coding RNA (lncRNA) that regulates DNA break repair in triple-negative breast cancer cells. It notes that while protein-coding genes make up less than 2% of the human genome, non-gene-encoding RNA constitutes 70%, significantly altering disease understanding. The specific lncRNA identified plays a critical role in maintaining genomic stability within these aggressive cancer cells.
Parts used in the Long-noncoding RNA Regulates DNA Repair Project:
- Long non-coding RNA (lncRNA)
- Triple-negative breast cancer cells
- DNA breaks
- Human genome
- Protein-coding genes
- Non-gene-encoding RNA
The discovery of long non-coding RNA (lncRNA) has dramatically changed the understanding of the biology of diseases such as cancer. The human genome contains about 20,000 protein-coding genes – less than 2 percent of the total – but 70 percent of the genome is made into non-gene-encoding RNA.
