Beyond birthmarks and beta blockers, to cancer prevention

Ahead of this week’s Morningside Center conference on repurposing drugs, we wanted to highlight a recent paper in NPJ Precision Oncology by dermatologist Jack Arbiser. It may represent a new chapter in the story of the beta-blocker propranolol. Several years ago, doctors in France accidentally discovered that propranolol is effective against hemangiomas: bright red birthmarks made of extra blood vessels, which appear in infancy. Hemangiomas often don’t need treatment and regress naturally, but some can lead Read more

Why HIV’s cloak has a long tail

Virologists at Emory, Yerkes and Children’s Healthcare of Atlanta have uncovered a critical detail explaining how HIV assembles its infectious yet stealthy clothing.

Paul Spearman, MD

For HIV to spread from cell to cell, the viral envelope protein needs to become incorporated into viral particles as they emerge from an infected cell. Researchers led by Paul Spearman have found that a small section of the envelope protein, located on its “tail”, is necessary for the protein to be sorted into viral particles.

The results were published June 1 in Proceedings of the National Academy of Sciences. Read more
