Molecular mechanisms involved in initiation of the DNA damage response
نویسندگان
چکیده
DNA is subject to a wide variety of damage. In order to maintain genomic integrity, cells must respond to this damage by activating repair and cell cycle checkpoint pathways. The initiating events in the DNA damage response entail recognition of the lesion and the assembly of DNA damage response complexes at the DNA. Here, we review what is known about these processes for various DNA damage pathways.

Nickel Increases Chromosomal Abnormalities by Interfering with the Initiation of DNA Repair Pathways
Background: Nickel is a carcinogenic, heavy metal released through industrial activities and via natural resources. It is able to cause DNA damages by reducing the efficiency of DNA repair mechanisms. However, the exact time point at which it is able to interfere with these mechanisms is not yet clearly understood. Methods: To find the most nickel-vulnerable time of repair mechanisms, human de...
متن کاملCellular and Molecular Mechanisms Involved in Neuroinflammation after Acute Traumatic Spinal Cord Injury
Introduction: Spinal cord injury (SCI) following traumatic events is associated with the limited therapeutic options and sever complications, which can be partly due to inflammatory response. Therefore, this study aims to explore the role of inflammation in spinal cord injury. The findings showed that the pathological conditions of nervous system lead to activation of microglia, astrocyte, neut...

Breast cancer is the most prevalent cancer in women. Chemotherapy is the main strategy in the treatment of this disease especially in the advanced form of the disease. Despite the recent progress in the development of new chemotherapy, the effectiveness of these drugs has dramatically reduced due to multidrug resistance. The phenotype of multidrug resistance (MDR) can occur through different me...

متن کاملنقش سلولهای گلیا در ایجاد دردهای نوروپاتی و بروز پدیده تحمل / پردردی اپیوئیدها
Common cellular and molecular mechanisms are not only involved in the development of neuropathic pain caused by neurological damage but also in the occurrence of the tolerance/hyperalgesia phenomenon caused by chronic use of opioids. It seems that the activation of the neuroimmune system in the brain and spinal cord is one of the most important mechanisms involved in the initiation and mainte...
