What keeps our cells the right size? Scientists have long puzzled over this fundamental question, since cells that are too large or too small are linked to many diseases.

The study shows that a long non-coding RNA called CISTR-ACT acts as a master regulator of cell size, influencing how large or small cells grow across multiple tissues.

Originally classified as ‘junk DNA’, genomic regions which are transcribed into RNAs that do not serve as template for protein production have attracted increasing attention in the last two decades.

These genes are part of the non-coding genome, which makes up about 98% of our DNA and was long dismissed as “junk.” This new ...

The non-coding genome, once dismissed as "junk DNA", is now recognized as a fundamental regulator of gene expression and a key player in understanding complex diseases. Following the landmark ...

Ischemic diseases, such as heart attacks and strokes, occur when blood flow to tissues is disrupted, leading to oxygen deprivation and cell damage. Traditional treatments like medication or surgery ...

Scientists are consistently one-upping each other when it comes to finding the oldest molecules from fossils. The race even includes the notoriously fragile RNA. “It’s groundbreaking,” said Oliver ...

How does a cell know when it’s been damaged? A molecular alarm, set off by mutated RNA and colliding ribosomes, signals danger. When the sun shines on your skin, what does it hit? When it causes a ...

A study by the Federal University of São Paulo describes how SARS-CoV-2 interacts with the RNA of infected lung cells in an unprecedented way. The results may guide the search for new treatments and ...
