Triple negative breast cancer develop resistance to chemotherapy by turning on molecular pathway

Researchers at The University of Texas MD Anderson Cancer Center have discovered that triple negative breast cancer cells can develop resistance to frontline, or neoadjuvant, chemotherapy not by acquiring permanent adaptations, but rather transiently turning on molecular pathways that protect the cells.

New study delves deeper into individual genomic differences than ever before

Human genomes vary quite a bit from individual to individual. These differences include single nucleotide changes, or "spelling mistakes" in the DNA sequence, but even more variation comes from structural variants, which include additions, deletions and rearrangements of large segments of DNA.
