How cell identity is preserved when cells divide

Posted by in categories: biotech/medical, chemistry, genetics

An MIT study suggests 3D folding of the genome is key to cells’ ability to store and pass on “memories” of which genes they should express.

Every cell in the human body contains the same genetic instructions, encoded in its DNA. However, out of about 30,000 genes, each cell expresses only those genes that it needs to become a nerve cell, immune cell, or any of the other hundreds of cell types in the body.

Each cell’s fate is largely determined by chemical modifications to the proteins that decorate its DNA; these modification in turn control which genes get turned on or off. When cells copy their DNA to divide, however, they lose half of these modifications, leaving the question: How do cells maintain the memory of what kind of cell they are supposed to be?

Research lays groundwork for promising new gene therapy approach for genetic heart disease: Clinical trials imminent

Posted by in categories: biotech/medical, genetics

Researchers at the Hubrecht Institute have laid the foundation for the development of a gene therapy for the genetic heart disease arrhythmogenic cardiomyopathy (ACM). Their approach, based on replacement of the PKP2 gene, led to significant structural and functional improvements in laboratory models of the disease.

The study by the group of Eva van Rooij was published on 7 December 2023 in Nature Cardiovascular Research. Multiple will start in 2024 in the United States to explore the clinical potential of this approach in ACM patients with PKP2 mutations.

ACM is a genetic disease that affects 1 in 2,000 to 1 in 5,000 people worldwide. It is characterized by arrhythmias and can lead to sudden cardiac arrest. Current treatment of the disease usually consists of antiarrhythmic drugs and implantable cardioverter-defibrillators (ICDs), which are focused solely on treating the symptoms rather than targeting the root of the problem.

SpaceX extends space-payload lead with early Thursday Starlink launch from Cape Canaveral

Posted by in categories: internet, satellites

Wednesday night, SpaceX announced Starlink high-speed internet is now available in Honduras, expanding its sizable service footprint across the Western Hemisphere.

Hours later, SpaceX launched a Falcon 9 rocket carrying 23 more Starlink satellites into low-Earth orbit from Cape Canaveral Space Force Station.

The late-night Falcon 9 soared off Launch Complex 40 at 12:07 a.m. EST Thursday, extending the ongoing record of annual orbital launches from the Space Coast to 68 — with another 24 days remaining in December.
