    Insights

    Targeting the DNA damage response (DDR) can enhance cancer therapies like radiation and chemotherapy. Exploiting DDR and DNA repair defects offers new strategies for synthetic lethality in cancer treatment.

    Area of Science:

    • Molecular Biology
    • Genetics
    • Cancer Research

    Background:

    • The DNA damage response (DDR) is essential for maintaining genomic stability and cell survival.
    • Dysregulation of DDR pathways is a hallmark of many cancers, presenting therapeutic opportunities.

    Discussion:

    • This review explores targeting key DDR elements to improve radiosensitization and chemosensitization.
    • Strategies for exploiting DDR and DNA repair defects in cancer cells for synthetic lethality are discussed.

    Key Insights:

    • Targeting DDR pathways can sensitize cancer cells to conventional treatments.
    • Synthetic lethality approaches leverage cancer-specific DNA repair deficiencies.

    Outlook:

    • Developing novel DDR inhibitors holds promise for overcoming treatment resistance.
    • Combination therapies targeting DDR are expected to advance cancer treatment paradigms.

    Treatment Resistant Cancers

    Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

    Targeted Cancer Therapies

    The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
    There are several types of targeted therapies against specific...

    Overview of DNA Repair

    In order to be passed through generations, genomic DNA must be undamaged and error-free. However, every day, DNA in a cell undergoes several thousand to a million damaging events by natural causes and external factors. Ionizing radiation such as UV rays, free radicals produced during cellular respiration, and hydrolytic damage from metabolic reactions can alter the structure of DNA. Damages caused include single-base alteration, base dimerization, chain breaks, and cross-linkage.

    DNA Damage Can Stall the Cell Cycle

    In response to DNA damage, cells can pause the cell cycle to assess and repair the breaks. However, the cell must check the DNA at certain critical stages during the cell cycle. If the cell cycle pauses before DNA replication, the cells will contain twice the amount of DNA. On the other hand, if cells arrest after DNA replication but before mitosis, they will contain four times the normal amount of DNA. With a host of specialized proteins at their disposal,cells must use the right protein at...
