Article Synopsis
- Carbon black nanoparticles (CBNPs) can cause DNA damage in human bronchial epithelial cells, but how this leads to cancer is not fully understood.
- Researchers created an in vitro model to study this and found that long-term exposure to CBNPs resulted in tumor-like transformations and persistent DNA damage.
- They discovered that a specific circular RNA, circ_0025373, helps protect against DNA damage by regulating a key DNA repair gene, MSH2, which could provide new insights into lung cancer treatment and the risks associated with CBNPs.
Microplastics (MPs) have received a lot of attention and have been detected in multiple environmental matrices as a new environmental hazard, but studies on human internal exposure to MPs are limited. Here, we collected lung tissue samples from 12 nonsmoking patients to evaluate the characteristics of MPs in human lung tissues using an Agilent 8700 laser infrared imaging spectrometer and scanning electron microscopy. We detected 108 MPs covering 12 types in the lung tissue samples, with a median concentration of 2.
