CRISPR Meets iPS: Technologies Converge to Tackle Sickle Cell Disease

Researchers from Johns Hopkins University have teamed two powerful technologies to correct sickle cell disease in a lab dish. Linzhao Cheng and colleagues have deployed CRISPR/Cas-9 on iPS cells to replace the mutant beta globin gene, published in Stem Cells.

ACRONYMS AND ABBREVIATIONS

CRISPR conjures up images of fried chicken, but it stands for “clustered regularly interspaced short palindromic repeats” – short repeated DNA sequences interspersed with areas called spacers, like stutters. The pattern of repeats and spaces attracts an enzyme, Cas9, which is like a molecular scissors that cuts wherever short RNA molecules called “guide RNAs” take it. Here’s a fuller descriptionRead More

"Animals Containing Human Material" -- Welcome!

A new biomedical abbreviation debuted July 22, ACHM (for Animals Containing Human Material) in a report of the same name from the UK Academy of Medical Sciences. ACHM will soon replace, I hope, the phrase “humans and animals,” which implies to the taxonomically inclined that we are instead fungus, plant, or microbe. Read More
