Insights

DNA damage response (DDR) defects are common in cancer. DDR-targeted therapies, initially for tumors, also impact immune cell interactions, offering new cancer treatment strategies.

Area of Science:

  • Oncology
  • Immunology
  • Genetics

Background:

  • The DNA damage response (DDR) is crucial for maintaining genome stability against genotoxic stress.
  • Aberrations in DDR pathways are a hallmark of cancer, presenting therapeutic targets.
  • DDR inhibitors are increasingly used in cancer treatment, with many in clinical trials.

Purpose of the Study:

  • To review the impact of DDR-targeted agents on the tumor-immune system crosstalk.
  • To explore how DDR inhibitors modulate interactions between tumor cells and immune components.
  • To understand the implications for developing novel cancer immunotherapies.

Main Methods:

  • Literature review of recent studies on DDR-targeted agents and cancer immunology.
  • Analysis of mechanisms by which DDR inhibitors affect immune cells directly.
  • Examination of how DDR inhibitors alter tumor cell molecules critical for immune interactions.

Main Results:

  • DDR-targeted agents can directly influence immune cell function.
  • These agents modify tumor cell expression of molecules involved in immune recognition and response.
  • The interplay between DDR defects, targeted therapies, and the immune system is complex and multifaceted.

Conclusions:

  • Understanding DDR-targeted therapy's immunomodulatory effects is vital for cancer treatment.
  • This knowledge can guide the rational design of combination therapies involving DDR inhibitors and immunomodulators.
  • Further research into the DDR-immune crosstalk may unlock new avenues for cancer therapy.

Targeted Cancer Therapies02:57

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...

Tumor Immunotherapy01:27

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Cytotoxic T Cells-mediated Immune Response01:27

Cytotoxic T Cells-mediated Immune Response

Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...

Overview of DNA Repair02:25

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 Cycle02:37

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...

Treatment Resistant Cancers02:56

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...
