Researchers developed RF-SIRF, a quantitative method to detect and map reversed DNA replication forks with single-cell resolution. The study identified unique epigenetic codes for DNA replication stress that can be further examined to understand genomic stability, aging, and treatment response.
Researchers at UT MD Anderson have made significant advancements in cancer care, including a blood-based biomarker for cancer risk in people with Lynch Syndrome and a new target to sensitize pancreatic tumors to immunotherapy. The studies also identified a strategy to overcome radiation therapy resistance in lung cancer.
A study published in Cancer Research has identified DPY30 as an epigenetic target that can sensitize pancreatic tumors to immunotherapy. By modulating DNA replication stress, DPY30 promotes the addition of activation signals at stressed replication forks, supporting cancer cell survival and proliferation.
Researchers at the University of Texas M. D. Anderson Cancer Center discovered that inflexible DNA within nucleosomes regulates the positioning of INO80, a chromatin remodeling complex. This unique mechanism allows INO80 to position itself on the surface of nucleosomes at the right location.
A research team led by Ivano Amelio found that the protein p53 acts as a key to maintaining genomic stability, preventing cancer-promoting mutations. Without p53, cells become more aggressive and prone to acquire genomic instability.
