What to know about Humans have a 'highly abundant' number of stable proteins that are not all predicted by genetic code

Researchers led by Nikolai Slavov have discovered that humans possess a significant number of stable proteins not predicted by the standard genetic code through a process called 'alternative RNA decoding.' The study, published in Nature, suggests these findings could eventually lead to new treatments for cancer and neurodegenerative diseases.

What happened

Humans have a 'highly abundant' number of stable proteins that are not all predicted by genetic code Lisa Lock Scientific Editor Robert Egan Senior Editor In 1968, the American biochemist and geneticist Marshall Nirenberg and his colleagues won the Nobel…

Why it matters

That discovery is considered a "fundamental pillar of molecular biology," explained Nikolai Slavov, a distinguished professor of bioengineering.

Common ground

"It's in every textbook from high school to college." For years, researchers have worked to build on Nirenberg's work and develop a deeper understanding of how proteins—which are responsible for muscle, skin and tissue maintenance—are formed.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
