21. Modelling and calculation of DNA damage and repair in mammalian cells induced by ionizing radiation of different quality
Abstract : Recent experimental data have revealed a wealth of information that provides an exceptional opportunity to construct a mechanistic model of DNA repair. The cellular response to radiation exposure starts with repair of DNA damage and cell signalling that may lead to mutation, or cell death. READ MORE

22. Homologous recombination at replication forks in mammalian cells
Abstract : Accumulating evidence indicates that homologous recombination plays an important role in mammalian cells, primarily in the reactivation of stalled replication forks. During a normal round of replication, stalling of the replication fork occurs frequently when a nick or a lesion, which cannot be by-passed, is encountered. READ MORE

23. Targeting MTHFD1 and MTHFD2 as cancer treatment
Abstract : One-carbon (1C) metabolism provides building blocks for nucleotide synthesis and therefore plays a central role in DNA replication and repair. To sustain rapid proliferation, cancer cells often upregulate their 1C metabolism, including the enzymes MTHFD1 and MTHFD2, as a part of their metabolic rewiring. READ MORE

24. Transcription Associated Recombination in Mammalian Cells
Abstract : There is increasing evidence that the movement of the transcription machinery through DNA has profound effects on the genomic stability. One such example is a phenomenon known as Transcription Associated Recombination (TAR). Transcription enhances recombination levels to a high degree in all organisms studied, from bacteria to mammals. READ MORE

25. Colorectal cancer and radiation response : The role of EGFR, AKT and cancer stem cell markers
Abstract : The primary treatment for colorectal cancer is surgery. Radiotherapy and chemotherapy, sometimes combined, are also frequently used to diminish recurrence risk. In response to radiation exposure, several cellular signaling cascades are activated to repair DNA breaks, prevent apoptosis and to keep the cells proliferating. READ MORE
