It’s not always the DNA
Scientists have mostly ignored mRNA, the molecule that ferries information from DNA to the cellular machines that make proteins, because these DNA transcripts are ephemeral and soon destroyed. But mRNA can be just as
important as DNA scientists at Washington University in St. Louis say. They found that oxidized messenger RNA jams the cellular machines that
make protein. The failure to clear the jams and chew up bad messengers
is associated with neurodegenerative diseases such as Alzheimer’s.
Oxygen near lens linked to cataracts in eye surgery patients
Yellowing of the eye due to age-related cataractResearchers at the School of Medicine may be a step closer to understanding what causes cataracts and what may help to prevent them. In a new study published in the American Journal of Ophthalmology, the researchers report oxygen may be the culprit.
Oxygen near lens linked to cataracts in eye surgery patients
Yellowing of the eye’s lens due to age-related nuclear sclerotic cataractResearchers at Washington University School of Medicine in St. Louis may be a step closer to understanding what causes cataracts, with the hope of one day being able to prevent them. In a new study published in the American Journal of Ophthalmology, the researchers report oxygen may be the culprit.
