Abstract

Insights

Alterations in DNA damage response (DDR) pathways are key in prostate cancer (PCa) development and treatment response. Understanding these DDR gene changes can improve PCa patient stratification and management.

Area of Science:

  • Oncology
  • Genetics
  • Molecular Biology

Background:

  • DNA damage response (DDR) pathway alterations are implicated in prostate cancer (PCa) initiation and progression.
  • These DDR alterations can affect patient responses to radiotherapy and anti-androgen therapies.
  • Aberrations in DNA repair genes in PCa suggest potential as biomarkers for patient stratification.

Purpose of the Study:

  • To review current knowledge on DDR alterations in PCa.
  • To explore the impact of DDR gene mutations on PCa etiology and progression.
  • To discuss the implications for clinical interventions and PCa management.

Main Methods:

  • Comprehensive literature review of clinical and preclinical studies.
  • Focus on the mechanisms underlying DDR gene mutations in PCa.
  • Analysis of the interplay between DDR and androgen receptor signaling.

Main Results:

  • DDR alterations significantly influence PCa development and treatment outcomes.
  • Understanding DDR mechanisms aids in selecting tailored treatment strategies, including Poly(ADP-ribose) polymerase inhibitors.
  • Crosstalk between DDR and androgen receptor signaling offers new therapeutic combination possibilities.

Conclusions:

  • Improved understanding of DDR mechanisms enhances PCa disease management.
  • Targeting DDR pathways provides novel therapeutic avenues for prostate cancer.
  • Ongoing research promises advancements in diagnostic, prognostic, and therapeutic approaches for PCa.

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

DNA Damage Can Stall the Cell Cycle02:36

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...

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.

Tumor Progression02:07

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
