What is Blue light exposure linked with?
2Studies link Blue light exposure with 2 measures, most often 5' UTR m6A methylation (1 study) and transcriptomic, epitranscriptomic, and metabolomic profiles (1).

Blue light exposure is associated with 5' UTR m6A methylation in flies.
“m6A methylation sites enriched in the 5' untranslated regions (UTRs) of Drosophila transcripts showed strong age specificity and could be altered by BLE.”

Blue light exposure is associated with transcriptomic, epitranscriptomic, and metabolomic profiles in flies.
“BLE could induce transcriptomic, m6A epitranscriptomic, and metabolomic reprogramming in Drosophila along with aging process.”
