Biological irradiators are specialized devices that deliver controlled doses of ionizing radiation to biological samples, such as cells, tissues, and small organisms. These tools are invaluable in cell and molecular biology research for a variety of applications.
Cell Cycle Arrest: Ionizing radiation can induce cell cycle arrest at specific checkpoints, allowing researchers to study the regulation of the cell cycle and the role of various proteins in cell cycle control.
Apoptosis Induction: Radiation can trigger programmed cell death (apoptosis), providing a model to study the molecular pathways involved in apoptosis and the role of different genes and proteins in this process.
Stress Response Pathways: Radiation can activate various stress response pathways, including those mediated by p53, NF-κB, and MAPK. Studying these responses helps researchers understand how cells respond to stress and damage.
Gene Expression Profiling: By irradiating cells and analyzing changes in gene expression, researchers can identify genes that are upregulated or downregulated in response to radiation, providing insights into cellular stress responses and adaptation mechanisms.
Stem Cell Differentiation: Radiation can influence the differentiation of stem cells, providing a tool to study the factors that regulate stem cell fate and the mechanisms of differentiation.
Stem Cell Niche: Researchers use irradiators to study the effects of radiation on the stem cell niche, including how radiation impacts the microenvironment and the interactions between stem cells and their niche.
