Reactivating a Naturally Occurring Gene Promotes Heart Repair and Regeneration

A naturally occurring gene called Cyclin A2 (CCNA2), which turns off after birth in humans, can actually make new, functioning heart cells and help the heart repair itself from injury including a heart attack or heart failure when the gene is turned back on.

New Method Doubles Therapeutic Cell Production for Duchenne Muscular Dystrophy

If cancer is a disease of overabundance, where cells divide without restraint and tumors grow despite the body's best interests, then degenerative diseases are disorders of deprivation.

Croatian Scientists Rewrite the Story of Cell Division

Scientists at the Ruđer Bošković Institute (RBI) in Zagreb, Croatia, have discovered that the protein CENP-E, long believed to act as a motor dragging chromosomes into place during cell division, in fact plays a completely different role in chromosome movement.

RyR1-Mediated CICR Plays Minimal Role in Normal Skeletal Muscle Contraction

Researchers engineered mice with a mutation (E3896A) in the RyR1 calcium-binding site, eliminating calcium-induced calcium release (CICR) without affecting depolarization-induced calcium release.

Discovery Reveals Spinal Neurons as Active Players in Sexual Behavior

For decades, it was thought that while the brain orchestrated male sexual behavior – arousal, courtship, and copulation – the spinal cord merely executed the final act: ejaculation. But a study from the Champalimaud Foundation (CF) challenges that tidy division.
