DNA Repair Biomarker Testing (ATM, ATR) in Cancer Studies
Understanding and identifying DNA repair biomarkers such as ATM (Ataxia Telangiectasia Mutated) and ATR (ATR Homologue) is crucial for the diagnosis, prognosis, and treatment of cancer. These biomarkers are involved in cellular responses to DNA damage and play a significant role in the development of targeted therapies.
The ATM protein kinase is essential for the repair of double-strand breaks in DNA through pathways like homologous recombination and non-homologous end-joining. Mutations or defects in ATM lead to increased sensitivity to ionizing radiation, which can be harnessed for diagnostic purposes. Similarly, ATR is involved in the checkpoint regulation during S-phase of cell cycle in response to genotoxic stress.
In cancer studies, DNA repair biomarker testing using techniques like immunohistochemistry (IHC), flow cytometry, and next-generation sequencing can provide critical insights into tumor behavior and predict patient responses to treatment. This information is valuable for clinicians and researchers aiming to develop more effective therapeutic strategies tailored to individual patients.
At our laboratory, we utilize advanced technologies and methodologies to ensure precise and reliable results. Our team of experts employs stringent quality control measures and adheres to international standards such as ISO 15189 and CAP accreditation criteria to maintain the highest level of accuracy in DNA repair biomarker testing.
The importance of these tests extends beyond mere identification; they offer a window into the molecular mechanisms underlying cancer progression. By understanding how efficiently cells can repair damaged DNA, we can better predict which patients might benefit most from certain treatments or require alternative therapeutic approaches.
