Abstract

Radiation-induced bystander effects (RIBE) can cause genomic damage in bone marrow mesenchymal stem cells (BMSCs) residing in the lung Cancer microenvironment. This effect appears in the short-term as well as in the long-term and can be characterized by different levels and types of cytokines. Depending on the degree of damage, stem cells have different survival fates. Here, we describe the molecular mechanism of tumor-associated BMSC genomic instability caused by differential changes of TGF-β1 and TNF-α in RIBE after different windows of analysis in the different time point clinical setting. We found that both short- and long-term RIBE induced genomic instability. We could show a high expression of TGF-β1, TNF-α, and HIF-1α in tumor-associated BMSCs after short-term RIBE whereas only TNF-α and HIF-1α expression was increased in long-term RIBE. We further confirmed that genomic instability is associated with the activation of the HIF-1α pathway and that this is mediated by TNF-α and TGF-β1. In addition, we found differences in the mechanisms of genomic instability in the considered RIBE windows of analysis. In short-term RIBE, both TNF-α and TGF-β1 play a role, whereas only TNF-α plays a decisive role in long-term RIBE. In addition, there were differences in BMSC recruitment and genomic instability of different tissues with a more pronounced expression in tumor and bone marrow than compared to lung. Therefore, our results may serve as a guideline for the administration of radiation protection Adjuvant drugs at different clinical stages.
