Air Pollution Leaves a Metabolic Mark
Prospective plasma metabolomics identifies pollution-associated metabolic changes linked to subsequent lung cancer risk
-
1
A metabolomics study linked long-term air pollution exposure to metabolic changes associated with lung cancer risk.
-
2
The study analyzed plasma samples from 1,357 cancer-free participants, with 671 later diagnosed with lung cancer.
-
3
Of 1,138 metabolites analyzed, 522 were associated with air pollution, and eight were linked to lung cancer risk.
-
4
Four metabolites were identified as potential intermediates between air pollution exposure and lung cancer risk.
-
5
The study's findings are observational and hypothesis-generating, with limitations in exposure measurement and population diversity.
