Imagine you’re visiting your doctor for a checkup. Your doctor takes all the usual measurements like your height, weight, heart rate, and blood pressure, and then tells you she’s going to sequence your DNA.

CRISPR Isn’t Just for Gene Editing Anymore
Posted by Genevieve Klien in categories: bioengineering, biotech/medical, genetics
A scientist cuts a DNA fragment under UV light for DNA sequencing. Image: AP Five years ago, when researchers first discovered that bacterial immune systems could be hijacked to edit DNA in living creatures, it was big news. The technology, called CRISPR, allowed scientists to more easily than ever cut and paste all those As, Cs, Ts, and Gs that make up the base pairs of DNA and encode the world’s living things. With CRISPR, scientists could use genetic engineering to tackle problems from disease to famine. But gene editing with CRISPR is so 2017. Recently, scientists have begun exploring n…

New Whitehead Institute research may prove to be a useful paradigm for targeting diseases caused by abnormal methylation. Credit: Steven Lee/Whitehead Institute Fragile X syndrome is the most frequent cause of intellectual disability in males, affecting one out of every 3,600 boys born. The syndrome can also cause autistic traits, such as social and communication deficits, as well as attention problems and hyperactivity. Currently, there is no cure for this disorder. Fragile X syndrome is caused by mutations in the FMR1 gene on the X chromosome, which prevent the gene’s expression. This abs…

In their paper published on the open access site Science Advances, the group describes testing the impact of CRISPR-Cas9 on phages that infect Escherichia coli and what they found. In nature, CRISPR-Cas9 is a defense mechanism used by bacteria t…

Lab-grown human cerebellar cells yield clues to autism
Posted by Genevieve Klien in categories: biotech/medical, neuroscience
This Purkinje neuron was derived from patients with tuberous sclerosis and model properties of the disease at the cellular and molecular level. Sundberg and colleagues first created induced pluripotent stem cells (iPSCs) from patients’ blood cells or skin cells, then differentiated them into neural progenitor cells and finally Purkinje cells. Credit: Courtesy Maria Sundberg, PhD, Sahin Laboratory, Boston Children’s Hospital Increasing evidence has linked autism spectrum disorder (ASD) with dysfunction of the brain’s cerebellum, but the details have been unclear. In a new study, researchers…
