Study Reveals ATM-Driven Mechanism Behind Telomere-Induced Senescence

After a finite number of divisions, cells simply give up. As each round of replication trims their telomeres-the protective caps at the chromosome ends-those caps eventually become too short to prevent chromosome ends from being recognized as DNA breaks.

DNA Rigidity Inside the Nucleosome Regulates INO80 Positioning

Researchers at The University of Texas MD Anderson Cancer Center have shown that DNA inflexibility, or rigidity, inside the nucleosome regulates the positioning of INO80. This highlights that the physical structure and shape of DNA, not just genetic information, are key components of DNA transcription.
